Background: Implant-based reconstruction (IBR) is the most common method of breast reconstruction after mastectomy. Prior studies have demonstrated that complications rates vary with incision type. We evaluated whether incision type affected culture positivity in IBR complications. Methods: A retrospective cohort study was performed of all patients undergoing mastectomy for cancer or cancer prophylaxis with IBR from 2012 to 2023. Abstracted data included patient characteristics, oncologic treatment history, mastectomy and reconstruction characteristics, culture positivity, infectious organism, and antibiotic treatment history. Results: A total of 6901 patients underwent post-mastectomy implant-based reconstruction, 183 (2.7%) patients had unplanned operative intervention for IBR complications, and 80/183 (43.7%) had culture-positive IBR infections. Culture-negative and culture-positive groups were similar in patient characteristics and oncologic treatment history. There was no difference in mastectomy incision types. The most common organisms were methicillin-sensitive Staphylococcus aureus, Pseudomonas aeruginosa, and coagulase-negative Staphylococcus. More patients in the culture-positive group were treated with antibiotics (81.2% vs. 51.5%, p = 0.0005). Antibiotic therapy duration was longer in the culture-negative group (8.52 vs. 5.78 days, p = 0.039). Among different incision types, there was no significant difference in duration of antibiotic therapy. Conclusions: No association between mastectomy incision type and culture-positive infections was observed among IBR complications in this study. Antibiotics may sterilize cultures, but operative intervention is still often required for IBR infections.

Background: Posterior cruciate ligament reconstruction (PCLR) remains one of the most technically demanding procedures in knee ligament surgery, with complication rates considerably higher than those observed for other arthroscopic procedures. Residual laxity, arthrofibrosis, neurovascular injury, tunnel-related complications, and heterotopic ossification (HO) represent the most frequent adverse events. With increasing surgical volumes and complexity—particularly in multiligament knee injuries (MLKIs)—structured, evidence-based strategies for complication avoidance are essential. The objective of this review is to provide a comprehensive, evidence-based overview of the main complications associated with PCLR and to propose a structured, reproducible protocol for complication prevention integrating current literature and high-volume institutional experience. Methods: A narrative review of the literature was conducted using PubMed and Google Scholar to identify clinical, biomechanical, and systematic studies on PCLR complications published between 2010 and 2025. Overall, 58 studies were screened and 33 were included for qualitative synthesis. Among the included studies, the level of evidence was Level I in five systematic reviews/meta-analyses, Level III–IV in seven observational clinical studies and registries, and Level V in biomechanical studies, narrative reviews, and expert consensus reports. In parallel, the recommendations were informed by the cumulative experience of a high-volume tertiary referral center with 187 PCLR procedures performed between 2010 and 2025 (136 MLKI, 51 isolated). Results: Evidence identifies several key predictors of postoperative complications: low posterior tibial slope (<6.54°), small graft diameter (<7.0 mm), untreated posterolateral corner insufficiency, excessive tibial tunnel angle, and surgical trauma at the “killer turn.” Neurovascular complications primarily arise during tibial tunnel instrumentation, with knee hyperflexion (>90°) significantly improving safety. Suture tape augmentation (STA) reduces graft elongation by 45–58% and is associated with improved biomechanical stability without increasing complication rates. Early controlled motion is critical to prevent arthrofibrosis, whereas HO—affecting up to 45% of MLKI patients—requires delayed surgical excision after maturation. Conclusions: Optimal outcomes after PCLR derive from a structured, complication-focused approach encompassing anatomical risk assessment, meticulous tunnel planning, neurovascular protection, biological augmentation, and disciplined postoperative rehabilitation. Adoption of standardized protocols—particularly in MLKIs—can substantially reduce the incidence of adverse events and improve long-term knee stability.

Introduction: Chordomas are rare, locally aggressive tumors of the spine and skull base typically managed with maximal surgical resection followed by adjuvant radiotherapy. Although postoperative radiotherapy improves local control, the optimal interval for initiation remains uncertain, as early delivery may exacerbate wound-related complications while delayed initiation may allow tumor progression. Methods: We performed a retrospective cohort analysis using the multi-center, national TriNetX Research Network. Adults with histologically confirmed skull base and/or spinal chordoma who underwent surgical resection followed by radiotherapy were stratified into ultraearly (≤2 weeks), standard (4–6 weeks), or delayed (≥10 weeks) radiotherapy initiation groups. Propensity score matching was used to adjust for demographic and clinical covariates. The primary outcome was all-cause mortality at 1, 3, and 5-years. Secondary outcomes included wound dehiscence, surgical site infection, and neurologic complications. Results: A total of 378 patients met the inclusion criteria. Ultraearly radiotherapy was not associated with significant differences in mortality at 1 year (RR 1.338; 95% CI 0.833–2.15; p = 0.22), 3 years (RR 1.233; 95% CI 0.858–1.772; p = 0.25), or 5 years (RR 1.196; 95% CI 0.876–1.633; p = 0.25) compared with standard timing. Delayed radiotherapy, however, demonstrated significantly reduced mortality at 1 year (RR: 0.53; 95% CI: 0.331–0.851; p = 0.01), 3 years (RR 0.641; 95% CI 0.449–0.914; p = 0.01), and 5 years (RR 0.654; 95% CI 0.473–0.905; p = 0.01) compared with standard timing. Event counts for secondary outcomes were insufficient for robust statistical comparison. Conclusions: Radiotherapy timing following surgical resection of chordoma did not impact short-term survival, but delayed radiotherapy significantly decreased 1, 3 and 5-year mortality. Rare secondary complications were seen. These findings suggest that the delayed initiation of radiotherapy may be helpful for patients with chordoma, supporting the need for prospective, long-term studies to clarify the balance between oncologic efficacy and perioperative morbidity.

Chronic subdural hematoma (CSDH) in frail older adults is increasingly recognized as a sentinel event, with mortality often driven by medical complications rather than neurosurgical factors. We report a failure-to-rescue case in which rapid postoperative deterioration occurred after burr-hole drainage for bilateral CSDH in a frail older adult with diabetes. A clinical picture consistent with sepsis was suspected, and a gastrointestinal source was considered, but the infectious focus could not be confirmed due to limited diagnostic work-up. On admission, chest-computed tomography showed mild right lower-lobe pneumonia, and incidental transverse colonic dilatation was also visible. Burr-hole drainage was uneventful and oxygenation rapidly normalized on room air. On postoperative day (POD) 3, the patient developed a high fever (39 °C), rising C-reactive protein (CRP; 14 mg/dL), abrupt leukopenia (15,300 → 3300/µL), and, several hours later, profuse watery diarrhea. At that time, an evaluation for an infectious source and escalation of therapy (e.g., blood cultures, serum lactate, and abdominal imaging) were not performed. In the early hours of POD 4, he suffered sudden desaturation, shock, and cardiac arrest, and died despite resuscitation. A portable radiograph after intubation showed no new diffuse pulmonary infiltrates but marked colonic gas distension. This case highlights the need to reassess diagnostic framing when discordant postoperative “red flags” emerge and proposes practical triggers for early sepsis evaluation and escalation—prioritizing early recognition and timely rescue rather than a definitive determination of the cause of death—in high-risk CSDH patients.

Carotid paragangliomas are rare neuroendocrine tumors that, despite being typically benign, present significant surgical and anesthetic challenges. This manuscript outlines the anesthetic management for surgical resection, highlighting preoperative assessment, intraoperative monitoring, and postoperative care. A multidisciplinary approach is essential, particularly for functional tumors, requiring preoperative screening and pharmacologic preparation. Intraoperatively, cerebral perfusion monitoring is critical to prevent ischemic events. Postoperative vigilance is necessary to detect complications such as bleeding, cranial nerve deficits, and hemodynamic instability. A multidisciplinary team skilled in these surgical procedures is essential to improve safety in carotid paraganglioma surgery.

Gallstone ileus is a rare but serious complication of gallstone disease, often requiring surgical intervention. While enterolithotomy remains the standard treatment, the role of additional biliary surgery, particularly subtotal cholecystectomy, remains controversial. This study examines the management of gallstone ileus in a rural setting, where limited surgical resources and access to specialized biliary interventions pose unique challenges. We present a case series of four patients diagnosed with gallstone ileus in a rural healthcare facility. All patients underwent initial enterolithotomy for bowel obstruction relief. Surgical outcomes, complications, and the necessity for a second intervention, including subtotal cholecystectomy, were evaluated. Ever patient had a successful recovery. Of the four cases, two patients underwent a subtotal cholecystectomy. No perioperative mortality was observed, but limited access to advanced imaging and specialized biliary surgery influenced clinical decision-making. The rural setting in which these series occurred comes with its unique challenges regarding resource management and technological demands.

Robotic retroperitoneal lymph node dissection (R-RPLND) represents an evolution in the surgical management of testicular germ cell tumors, offering reduced morbidity compared with open approaches. However, this procedure remains technically challenging, particularly after chemotherapy, due to dense fibrosis and distortion of the retroperitoneal anatomy. We report a case of an unrecognized intraoperative thermal injury causing a partial transection of the proximal ureter presenting postoperatively as a urinary fistula following R-RPLND for residual mass resection, along with a focused review of the contemporary literature on procedure-related complications. A review of large series highlights severe complications (Clavien–Dindo ≥ III) occurring in 6–12% of cases, with ureteral injuries occurring in up to 6%, often identified after surgery. This case underscores the importance of meticulous dissection, awareness of altered anatomy, and prompt intervention when unexpected events arise during R-RPLND.

Spinal sarcomas are rare, aggressive tumors requiring wide resection that creates large, challenging defects. Conventional reconstruction using allografts or metallic implants is prone to failure in compromised settings like irradiated or infected tissue. This narrative review synthesizes the literature on biologic reconstruction strategies, focusing on vascularized bone grafts (VBGs) and the ‘spinoplastic’ reconstruction approach, to provide a clinical framework for their application. We performed a narrative literature review using PubMed and Scopus to synthesize clinical studies describing biologic spinal reconstruction in compromised host beds. The main findings show that pedicled VBGs (e.g., rib, iliac crest) and free VBGs (e.g., fibula) function as living structural components. ‘Spinoplastic’ reconstruction leverages these grafts to promote biologic fusion, with clinical series reporting high union rates, even in irradiated or revision settings, offering a durable alternative to avascular constructs. Biologic reconstruction using VBGs is a critical strategy for achieving durable spinal stability in these challenging scenarios, and future directions point toward hybrid strategies combining 3D-printed implants with the biologic power of VBGs.

Introduction: Rerouting urine flow is often required following radical cystectomy (RC). In this context, the ileal conduit (IC) has become the most common technique for urinary diversion, primarily due to its technical simplicity and suitability for patients with compromised renal function, elderly individuals, and those unable to perform self-catheterization. Objective: This review aims to highlight the complications of IC and categorize them into metabolic and surgical complications, further subdivided by timing (intraoperative, short-term, intermediate-term, and long-term) and anatomical location (uretero-ileal anastomosis, stoma, and ileal segment). Methods: A comprehensive narrative review was conducted to summarize the most common complications of IC, their clinical presentation, and management using Google Scholar, PubMed, and Embase databases to identify studies published from 1950 to 2024. Results: The morbidity associated with IC, especially when compared to continent diversions, remains a subject of debate. Notably, IC-related complications have been described with an incidence rate ranging from 39% to 67%. Conclusions: Providing a comprehensive overview of IC complications and management strategies can enhance clinical practice and improve patient outcomes.

Ankle fractures are extremely common and often require surgical management, historically with open reduction and internal fixation (ORIF), although fibular intramedullary nailing (IMN) has demonstrated promising results in recent years. The purpose of this study is to report on risk factors, quality of reduction, and complications in a series of patients undergoing fibular IMN for management of ankle fractures using a novel device via a retrospective case series. Patients undergoing locked fibular IMN with the Flex-Thread nail (Conventus Flower Orthopedics, Horsham, PA, USA) by a single surgeon from January 2023 to March 2025 were included, with at least 6 months of follow-up. Demographics, comorbidities, injury characteristics, reduction quality, and post-operative complications were recorded. Descriptive analyses were reported for categorical variables. A total of 15 patients were included, with a mean age of 58.9 ± 22.0 (range 18–91) and mean BMI of 31.5 ± 5.7 kg/m2. All patients experienced a fall as their mechanism of injury, with 12 Weber B and 3 Weber C fractures. The mean time to surgery from the date of injury was 9.5 ± 5.5 days. Of 15 patients, 66.7% had good reduction quality, 26.7% had fair, and 1 patient experienced poor reduction quality requiring subsequent hardware removal. There was one patient who experienced delayed wound healing. Patients undergoing fibular fixation using the novel Flex-Thread nail experience a fair to good quality of reduction, with limited complications. Both young and elderly patients have relatively positive early post-operative outcomes. Additional research with longer-term follow-up will be required to confirm its efficacy.

This study analyzed complication rates, perioperative metrics, and hospital readmissions across BMI cohorts in patients undergoing direct anterior approach (DAA) total hip arthroplasty (THA) in a mature hip practice. Currently, the precise BMI cutoff points for risk in THA are not fully understood. A retrospective review was conducted of patients who underwent DAA THA by a single, highly experienced, fellowship-trained surgeon between January 2021 and January 2023. The use of single-surgeon cases allows for control of many potentially confounding variables but may limit the generalizability of the findings. Data collected included patient demographics, hospital readmissions, 12-month complication rates, and intraoperative metrics. Patients with Class II obesity (BMI 35–39.9) kg/m2 and Class I obesity (BMI 30–34.9) kg/m2 had significantly higher intraoperative blood loss and longer operative times compared to the control group (BMI 20–24.9 kg/m2). No statistically significant differences in hospital readmission rates or complication rates were observed between BMI cohorts. Higher BMI was associated with increased intraoperative blood loss and longer operation time; however, no differences were found in hospital readmissions or complication rates between BMI cohorts.

Diabetic foot ulcers drive non-traumatic lower-limb amputation; limb salvage surgery is often pursued to preserve function and survival. Predictors of adverse outcomes remain incompletely defined, and evidence for multidisciplinary team (MDT) care is heterogeneous. We aimed to clarify risk factors for major amputation and death after diabetic limb salvage and evaluate MDT impact. We systematically reviewed 49 studies (2020–2025) reporting major amputation or mortality after limb salvage in diabetes (PROSPERO CRD420251044859). Risk factors spanned demographic, clinical, and surgical domains (e.g., older age, male sex, renal/cardiovascular disease, ischemia, osteomyelitis, advanced ulcer classification). MDT models generally showed lower amputation rates and improved wound healing, with occasional survival benefits; heterogeneity precluded meta-analysis. As a real-world comparator, the Mid Essex Diabetes Amputation Reduction Plan (MEDARP) treated 72 high-risk patients using a “toe and flow” MDT. Major amputation occurred in 6.9% and mortality in 12.5%, both at or below published ranges, with gains in patient-reported outcomes. Findings support MDT-based strategies, but conclusions should be interpreted cautiously given the predominantly observational evidence, and highlight the need for standardized outcome definitions and reporting.

Introduction: Tobacco smoking is a known risk factor for adverse surgical outcomes, including delayed wound healing and an increased risk of infection and nonunion. The rising use of cannabis products and alternative nicotine products, such as smokeless tobacco and electronic cigarette devices present new challenges for perioperative management, yet their influence in foot and ankle surgery is not well studied. Objectives: This scoping review aims to synthesize the existing literature on tobacco use, cannabis, and electronic cigarettes and their influence on postoperative outcomes in foot and ankle surgery. Methods: A comprehensive search of PubMed was performed using PRISMA-ScR guidelines. Eligible studies included observational studies and reviews that focus on the relationship between perioperative substance use and foot and ankle surgery complications. Results: There is a wide range of evidence that supports increased wound and bone healing complications with use of combustible tobacco. Data on the effects of smokeless tobacco, electronic cigarettes, and cannabis on this patient population is limited, with most evidence drawn from animal studies or broader orthopaedic literature. Conclusions: The existing data raises potential concern for adverse effects with use of these products. By identifying existing findings and gaps in the literature, this review highlights the need for further research on the perioperative effects of these substances in foot and ankle surgery.

Background: Despite advances in surgical techniques and perioperative care, pancreatic resections such as pancreaticoduodenectomy (PD) and distal pancreatectomy (DP) remain high-risk procedures. Postoperative complications significantly impact morbidity, mortality, and patient quality of life. Methods: This narrative review summarizes recent literature on major complications following pancreatic surgery, including postoperative pancreatic fistula (POPF), delayed gastric emptying (DGE), and post-pancreatectomy hemorrhage (PPH), with an emphasis on incidence, risk factors, outcomes, and current preventive strategies. Results: POPF is a leading complication, occurring in 5–22% of cases and often linked with sepsis and hemorrhage. Key risk factors include high BMI, soft pancreatic texture, and small duct size. Preventive measures like Pasireotide, modified anastomosis techniques, and neoadjuvant therapy show variable success. DGE affects up to 57% of PD patients and is associated with prolonged recovery; antecolic reconstruction and erythromycin may reduce incidence. PPH, though less frequent (3–13%), can be life-threatening, particularly when secondary to POPF. Endovascular approaches are now favored for late arterial bleeding. Other complications include wound infections, abscesses, bile leaks, and pulmonary issues, all contributing to extended hospital stays and diminished quality of life. Conclusions: Pancreatic surgery continues to carry significant risks, with POPF, DGE, and PPH being the most impactful complications. While multiple interventions have shown promise, standardized protocols and predictive tools are still needed. Surgery should be performed in high-volume centers with experienced multidisciplinary teams to optimize outcomes.

Necrotizing soft tissue infection (NSTI) is a rapidly progressive, life-threatening soft tissue infection that involves the skin, subcutaneous tissue, and fascia, with a natural evolution to septic shock and death if not treated. NSTI is typically associated with trauma, and rarely reported as a complication of aesthetic procedures such as liposuction. We report the case of a previously healthy 34-year-old woman who developed fulminant necrotizing soft tissue infection shortly after undergoing abdominal liposuction in a suspected non-accredited facility. She arrived at our institution with severe thoracoabdominal pain, ecchymosis, and refractory shock within hours postoperatively. Imaging studies performed in the emergency department revealed gas in the soft tissues, confirming the diagnosis. Emergent surgical debridement exposed extensive necrosis affecting a large body surface area. The patient required multiple surgeries, intensive care support, and broad-spectrum antibiotics to achieve infection control. Reconstructive treatment was initiated once stabilization was achieved, leading to full wound closure and a favorable clinical outcome. In addition, we provide a comprehensive review of the current literature regarding necrotizing soft tissue infection, emphasizing this condition as a postoperative complication, including its epidemiology, microbial etiology, pathophysiology, diagnostic challenges, treatment strategies, and reported cases. This review aims to contextualize this rare but severe postoperative complication and to guide clinicians in its early recognition and management, while also raising awareness about the potential consequences of aesthetic procedures performed in unregulated settings.

Percutaneous vertebroplasty (PVP) has emerged as a key intervention for painful vertebral compression fractures in osteoporotic and metastatic disease, but its safety profile warrants comprehensive evaluation. We conducted a PRISMA-compliant systematic review of studies published between 2009 and 2024, identifying 15 clinical studies (n ≈ 8500 patients) that reported PVP-related complications in adults with osteoporotic or neoplastic fractures. Data extraction focused on complication incidence, presentation, imaging findings, risk factors, and management strategies. Cement leakage was the most frequently detected event (20–70% of levels, higher in neo-plastic lesions), yet symptomatic neural or vascular sequelae occurred in <1%. Pulmonary cement embolism appeared on imaging in 2–26% of cases but was clinically evident in ≤0.5%, with conservative management or brief anticoagulation sufficing for most patients. New vertebral fractures developed in 8–20% of osteoporotic and up to 30% of metastatic cohorts, paralleling underlying bone fragility rather than PVP itself. Postprocedural infection (0.2–0.5%) and neurologic injury (<0.5%) were uncommon but required prompt surgical and antibiotic interventions. Overall, PVP’s benefits—rapid pain relief and mechanical stabilization—outweigh its risks when performed with meticulous technique, vigilant imaging, and multidisciplinary follow-up, confirming its favorable safety profile in both osteoporosis and spinal malignancy.

Background/objectives: Robotic-assisted partial nephrectomy (RAPN) is increasingly utilised for the management of renal masses, with the growing use of different robotic platforms and increasing complexity of renal masses managed robotically. Appropriate patient selection, the development of operative skills and experience and sensible surgical decision making are required to optimise the outcomes of RAPN and minimise the risk of complications. We provide a comprehensive review of strategies to predict, avoid and manage the complications of RAPN. Methods: We conducted a comprehensive literature review to outline many of the reported complications arising from RAPN, with a focus on preoperative considerations (patient selection, imaging, 3D modelling and predictive models), intraoperative considerations (positioning and kidney exposure complications) and practical management strategies to identify and manage the complications of this procedure. Results: Many complications of RAPN can be predicted, and we outline strategies to mitigate these risks through careful preparation prior to surgery, including descriptions of preventative strategies and important preoperative considerations. We also present a detailed outline of management for the most common complications of RAPN, including bleeding/haemorrhage, urine leak and intraoperative complications such as adjacent organ injuries. Conclusions: RAPN can be a challenging procedure with a significant risk of complications. Assiduous preoperative planning, thoughtful intraoperative decision making and the early recognition and management of complications are essential to optimise patient outcomes following RAPN.

Penile cancer is a rare malignancy, with approximately 2100 cases diagnosed annually in the United States. The 5-year overall survival rate varies significantly depending on the node involvement status, at 79% in node-negative disease versus 51% for patients with inguinal metastasis. Inguinal lymph nodes are involved in micrometastatic disease in up to one out of four patients. Early inguinal lymph node dissection (ILND) has been shown to provide a survival advantage, which is why many patients undergo inguinal lymph node dissection for diagnostic and therapeutic purposes. Unfortunately, ILND is associated with high morbidity rates, which have led to potential overtreatment and decreased quality of life in the penile cancer population. Several advancements have been made to mitigate these challenges, such as dynamic sentinel node dissection, modifications to the technique or surgical templates, the introduction of minimally invasive procedures, and changes to the postoperative pathway. This manuscript examines the evolution in managing the inguinal lymph nodes in penile cancer, its associated complications, and effective strategies for their prevention and management.

Introduction: Haglund’s deformity, characterized by bony enlargement at the back of the heel, often coincides with Achilles tendon pathology due to impingement on the retrocalcaneal bursa and tendon insertion. Surgical management of Haglund’s deformity with a preexisting Achilles tendon rupture is complex, and understanding the outcomes of this subset of patients is essential for optimizing treatment strategies. Methods: This retrospective study reviewed patients undergoing open surgical management for Haglund’s syndrome between January 2015 and December 2023. Patients with chronic degenerative changes secondary to Haglund’s deformity and a preoperative Achilles tendon rupture were compared to those without. Data on demographics, surgical techniques, weightbearing protocols, and complications were collected. Univariate analysis was performed using χ2 or Fisher’s exact test for categorical variables, and the T-test or Wilcoxon rank-sum test for continuous and ordinal variables, with normality assessed via the Shapiro–Wilk test. Results: Four hundred and three patients were included, with 13 having a preoperative Achilles tendon rupture. There was a higher incidence of preoperative ruptures among males. Surgical repair techniques and postoperative weightbearing protocols varied, though were not randomized. Complications included persistent pain, wound breakdown, infection, plantar flexion weakness, and revision surgery. While patients with Haglund’s deformity and a preoperative Achilles tendon rupture demonstrated a trend toward higher complication rates, including postoperative rupture and wound breakdown, these differences were not statistically significant in our analysis. Conclusions: A cautious approach is warranted in managing these patients, with careful consideration of surgical planning and postoperative rehabilitation. While our findings provide valuable insights into managing patients with Haglund’s deformity and preoperative Achilles tendon rupture, the retrospective design, limited sample size of the rupture group, and short duration of follow-up restrict generalizability and the strength of the conclusions by limiting the power of the analysis and underestimating the incidence of long-term complications. Therefore, the results of this study should be interpreted with caution. Further studies with larger patient cohorts, validated functional outcome measures, and comparable follow-up durations between groups are needed to confirm these results and optimize treatment approaches.

Laparoscopic urological surgery has become a cornerstone in the management of diverse urological pathologies, offering substantial advantages over traditional open approaches. These benefits include minimized incisions, reduced tissue trauma, decreased intraoperative blood loss, lower postoperative pain, shorter hospital stays, superior cosmesis, and accelerated recovery. Despite these advantages, laparoscopic surgery carries inherent risks, with major vascular injury (MVI) representing one of the most severe and potentially life-threatening complications. This review examines the incidence, etiologies, and management strategies for MVI in laparoscopic urological surgery, emphasizing the critical role of early recognition, standardized protocols, and surgical expertise in optimizing patient outcomes.

Endodontic perforations are serious complications encountered in the dental setting. Early detection, diagnosis, and proper management of perforations are crucial for a favorable prognosis. However, there are a limited number of studies that provide an overview of perforations, emphasizing these three strategies: prevention, diagnostic challenges, and management. The objective of this narrative review is to highlight the multifaceted components of endodontic perforations while also identifying the most effective methods used in their detection, diagnosis, and management. An electronic literature search was conducted using various databases and applying keywords for articles published in English. Eligible papers were reviewed further to gather relevant information. The results of the literature search found that, although perforations are relatively uncommon occurrences in the clinical setting, they still need to be understood for the prevention and treatment of these iatrogenic complications. The combination of case complexity and limited operator experience often determines the likelihood of endodontic perforation occurrence. Accurate diagnosis and identification of perforations rely heavily on the combination of clinical examination and advanced imaging technologies. In recent times, new technologies have emerged and hope to contribute to a decreased occurrence of endodontic perforations and increased prognosis in cases that do arise.

Background/Objectives: This study aimed to evaluate the prognostic significance of preoperative inflammatory biomarkers—C-reactive protein-to-albumin ratio (CAR), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR)—in predicting early postoperative complications (within 30 days) in patients undergoing percutaneous endoscopic gastrostomy (PEG). Methods: Data from 184 patients who underwent PEG placement at our institution between January 2021 and May 2022 were retrospectively analyzed. Demographic characteristics, PEG indications, and preoperative laboratory parameters (CRP, albumin, neutrophils, lymphocytes, and platelets) were recorded. CAR was calculated as the ratio of CRP (mg/L) to albumin (g/dL). Complications occurring within 30 days post-procedure were defined as early postoperative complications. Patients with and without complications were compared, and logistic regression analysis was used to identify potential risk factors. Results: The mean age of the patients was 71.5 ± 5.9 years, and 58.7% were male. PEG indications included neurological dysphagia (54.3%), head and neck malignancies (21.7%), and other causes (23.9%). At least one early complication occurred in 26 patients (14.1%). There were no significant differences in age, sex, body mass index, or Charlson Comorbidity Index between patients with and without complications (p > 0.05). Logistic regression revealed that elevated CAR was an independent predictor of postoperative complications (OR = 2.88; 95% CI: 1.62–5.13; p < 0.001). Although NLR (OR = 1.34) and PLR (OR = 1.02) were also associated with increased risk, they were less predictive than CAR in multivariate analysis. Conclusions: Preoperative CAR, NLR, and PLR levels are valuable biomarkers for predicting early complications following PEG. Notably, higher CAR levels are significantly associated with increased complication risk. Incorporating these indicators into clinical decision-making could facilitate early identification of high-risk patients and implementation of preventive strategies.

Background: People with spinal cord injury/disorder are at a high risk of pressure injury formation, and, in advanced cases, surgery is mandatory. These patients present specific clinical aspects to consider in order to reduce the risk of complications. This paper is a narrative review and expert opinion based on the authors’ institutional experience of over 10 years in a spinal unit. The specific protocols of treatment based on a multidisciplinary approach, protocols of flap selection, and strategies to prevent and manage complications are reviewed. The specific clinical aspects of each patient that should be considered during treatment to optimize the results and to reduce complication rates are reviewed. Conclusions: A multidisciplinary team approach and specific protocols for patient management allow for a reduction in complication rates in the surgical treatment of pressure injuries in spinal cord injury patients and implement an overall success rate. Complications management protocols should be developed and investigated to further improve the overall success rate.

Transseptal puncture (TSP) is an essential step for left heart procedures that allows access to the left atrium (LA) through the fossa ovalis (FO) of the interatrial septum (IS). Initially developed for diagnostic purposes, today, it is performed for procedures that require large-bore device delivery systems and complex three-dimensional navigation in the left atrium. TSP supports various interventions, including atrial fibrillation ablation, left atrial appendage closure, and transcatheter mitral valve repair and replacement. While traditionally performed with Brockenbrough needles under fluoroscopic guidance, the integration of transesophageal and intracardiac echocardiography (TEE/ICE) has significantly improved its safety and precision. Despite its generally high success rate, TSP poses challenges in complex anatomies or for less experienced operators, with complications such as cardiac tamponade, aortic root puncture, and embolic events. Anatomical variations, such as thickened or floppy septa, further complicate the procedure. Technological advancements, including radiofrequency-based systems and specialized guidewires, have enhanced safety in difficult cases. Effective training, including echocardiography and complication management, is vital for operator proficiency. This review outlines the procedural steps for safe TSP, emphasizing proper equipment selection, anatomical considerations, and vascular access techniques. Common complications are discussed alongside management strategies. Advanced tools and techniques for addressing challenging scenarios are highlighted.

Background: Surgical complications are devastating both for patients and treating surgeons. When complications occur after bariatric procedures, due to specific characteristics of this population, management, although multidisciplinary, should always be led by a surgical team. Methods: We present major complications treated at our general surgery service over a seven-year period. Case series: We present five cases that were treated at our service after a bariatric procedure was performed. Two patients were operated on in another country and two more at another service. Three patients showed perforation and leak-related complications. One patient died due to refeeding syndrome complications after revisional surgery. Conclusions: Optimal preoperative evaluations and surgical planning are mandatory for any type of surgery including bariatric procedures, and attempting adequate and well-established surgical techniques extensively described in the medical literature is associated with better outcomes. It is also our understanding that easy channels of communication between patients and treating surgeons could avoid delays in detecting and treating life-threatening conditions.

Background/Objectives: Deep inferior epigastric perforator (DIEP) flap reconstruction is considered the gold standard for autologous breast reconstruction due to its favorable aesthetic results and low donor site morbidity. Nevertheless, it remains associated with potentially life-threatening complications such as deep vein thrombosis (DVT) and pulmonary embolism (PE). This report aims to describe a complex clinical case in which severe thromboembolic and ischemic complications occurred despite adherence to standard prophylactic protocols. Methods: We present the case of a 65-year-old female with multiple thromboembolic risk factors—including obesity, a history of heavy smoking, hormone therapy, and prior COVID-19 infection—who underwent immediate bilateral breast reconstruction with DIEP flaps following mastectomy. Results: Within the first 24 h postoperatively, the patient developed a massive pulmonary embolism requiring intensive care management. Despite appropriate anticoagulation and supportive measures, she subsequently experienced full-thickness necrosis of the central portion of the abdominal flap. Thrombophilia screening and diagnostic imaging did not reveal peripheral venous thrombosis, raising the hypothesis of a hypercoagulable state potentially related to prior SARS-CoV-2 infection. Conclusions: This case underscores the importance of individualized risk stratification and suggests that current prophylaxis protocols may be insufficient for patients with overlapping thrombotic risk factors. The findings advocate for further investigation into the long-term vascular effects of COVID-19 and support reconsidering extended or intensified prophylaxis in high-risk populations undergoing complex microsurgical procedures.

Pelvic organ prolapse (POP) is a prevalent condition worldwide with detrimental effects on patients’ quality of life. Laparoscopic sacrocolpopexy (LSC) has emerged as the gold standard for managing complex and high-grade POP. While anatomical and subjective outcomes have been extensively documented, the management of its associated complications, particularly urinary incontinence, remains challenging. This study evaluates the strategies implemented to address complications arising from LSC, focusing on urinary incontinence. A retrospective multicenter study analyzed 325 patients who underwent LSC using lightweight macroporous Surelift Uplift mesh between 2011 and 2019. Data on perioperative and long-term complications, with emphasis on urinary incontinence management, were extracted from participating centers. Among them, the incidence of new-onset stress urinary incontinence (SUI) postoperatively was 12.9%. A total of 21 patients required further treatment for urinary symptoms, including mid-urethral sling (MUS) procedures in 5.5% and botulinum toxin injections for overactive bladder (OAB) in 0.9%. The findings underscore the importance of proactive and tailored management strategies for urinary incontinence following LSC. While the procedure demonstrates low complication rates and high anatomical success, urinary symptoms require vigilant monitoring and intervention in a two-step procedure for stress incontinence, if needed.

A periprocedural prosthetic valve leak (PVL) after transcatheter aortic valve implantation (TAVI), a minimally invasive treatment modality for patients with severe, symptomatic aortic stenosis, may entail serious morbidity. Cohorts hospitalized for TAVI from a national database (2016–2020) were stratified on the presence of PVL post-TAVI. TAVI patients with and without PVL were selected for propensity score matching. Pearson’s x2 test was used to compare outcomes. Among 319,448 TAVI patients over five years, 2043 had periprocedural PVL identified at index hospitalization, acute heart failure (49.61% vs. 41.15%, p < 0.001), acute kidney injury (20.40% vs. 11.77%, p < 0.001), cardiac tamponade (1.31% vs. 0.52%, p < 0.05), higher inpatient mortality (3.05% vs. 1.05%, p < 0.001), postprocedural bleeding (3.5% vs. 1.48%, p < 0.001), sudden cardiac arrest (15.34% vs. 8.54%, p < 0.001), and vascular complications (4.10% vs. 1.57%, p < 0.001). TAVI with PVL was associated with a significantly longer length of stay (p < 0.05) and total cost of hospitalization (p < 0.05). The 30-day (15.2% vs. 12%, p = 0.02), 90-day (24.4% vs. 19.9%, p < 0.01), and 180-day (34.7% vs. 24.8%, p < 0.01) readmission rates were significantly higher in the TAVI cohort with PVL. PVL in patients post-TAVI is associated with greater mortality and morbidity during index hospitalization, higher readmission rates, and increased burden on healthcare costs and infrastructure.

This review explores current strategies aimed at reducing complications in gynecologic surgery, focusing on innovations in laparoscopic entry techniques, extraperitoneal lymphadenectomy, and alternative approaches such as gasless laparoscopy. We conducted a comprehensive literature review, including studies and technical descriptions relevant to improved surgical access, lymph node dissection, and overall risk mitigation. Key findings indicate that the individualized selection of entry points—ranging from Palmer’s point in the left upper quadrant to the recently described Jain point—can minimize vascular and bowel injuries, especially in patients with prior abdominal surgeries. Furthermore, extraperitoneal lymphadenectomy appears to lower adhesion formation and bowel handling, potentially decreasing postoperative morbidity in oncologic cases. Gasless laparoscopy may offer comparable surgical outcomes with improved cardiorespiratory stability in high-risk patients, although visualization challenges remain. Overall, the evidence suggests that advanced minimally invasive methods and tailored procedural planning can effectively enhance patient safety and reduce postoperative complications. These approaches, however, demand a high level of surgical expertise, thorough preoperative imaging, and an institutional framework that supports training and ongoing quality monitoring. Continued investigations, including prospective trials and larger sample sizes, are required to validate these findings and further refine protocols aimed at optimizing outcomes in gynecologic surgery.

Introduction: Uterine transplantation is currently the only treatment that allows women with absolute uterine factor infertility (AUFI) to gestate and give birth. Objective: This systematic review aims to analyze the available evidence on uterine transplantation, focusing on the medical process, associated complications, ethical dilemmas, and the psychological and social impact on recipients. Methods: A systematic review of PubMed, Medline, MedNar, and Cinahl databases was conducted. The inclusion criteria included articles related to uterine transplantation published in English or Spanish between 2019 and 2024, excluding animal studies or other uterine procedures. Results: A total of 46 articles were analyzed. The review describes ethical considerations and recipients’ perceptions, two variables that have received limited attention in recent studies. Additionally, the transplant and gestation processes, along with associated complications, were detailed. Discussion: The limited availability of studies on ethical aspects and recipient perceptions presented challenges in the research. Moreover, the role of nurses and midwives, despite their importance in the process, is scarcely discussed in the literature. Conclusions: Although uterine transplantation remains an emerging treatment, its development suggests that the benefits may outweigh the risks, offering new hope for women with AUFI.

Fat embolism syndrome (FES) is a rare multisystem disorder caused by the dispersion of fat emboli in the systemic circulation. FES typically occurs after orthopedic trauma and classically manifests as a triad of respiratory failure, neurologic impairment, and petechial rash. Ophthalmic involvement is uncommon in the absence of cardiac or pulmonary arteriovenous shunts and presents with diffuse retinal hemorrhages and accompanying visual disturbances. We report a case of FES and Purtscher-like retinopathy following the surgical repair of a comminuted femur fracture in a previously healthy 19-year-old male without a known predisposing cause and document the course of successful recovery.

Purpose: Percutaneous nephrolithotomy (PCNL) is the gold-standard treatment for large renal calculi. Despite its efficacy, complications can occur. This narrative review aims to classify, manage, and prevent PCNL complications, emphasizing risk factors and strategies to optimize outcomes. Findings: PCNL is a safe and highly effective procedure for the management of renal stones. Risk factors include patient comorbidities, stone complexity, prolonged surgical time, and improper access. Proactive measures, such as accurate imaging, antibiotic prophylaxis, and careful surgical techniques, reduce complication rates. Although certain complications may affect surgical outcomes, most are effectively managed through conservative or minimally invasive approaches. Proficiency in the technique is essential for reducing the risk of complications. Conclusions: Understanding the classification, risk factors, and management of PCNL complications is essential for optimizing patient outcomes. Comprehensive preoperative planning, meticulous surgical technique, and tailored postoperative care are critical for minimizing risks and improving procedural safety.

This case report outlines the intricate clinical management of a 5-month-old infant with recurrent bacterial infections and a non-healing umbilical ulcer following the surgical excision of a urachal remnant. The infant’s medical history was significant for delayed umbilical cord detachment and multiple surgical site infections. The initial surgical approach included the excision of the residual urachus, wound debridement, and abdominal wall reinforcement using a collagen matrix combined with local flap closure. Despite an apparently uneventful postoperative course, the wound experienced dehiscence and failed to heal. As part of the diagnostic workup, genetic testing was conducted, revealing an autosomal dominant mutation in the RAC2 gene, which impairs neutrophil function. Given the urgent need for wound closure prior to hematopoietic stem cell transplantation (HSCT), further debridement and sessions of negative pressure therapy were performed, alongside attempted repair with acellular dermal regeneration matrices, which ultimately proved to be ineffective. Ultimately, HSCT was undertaken despite the infectious associated risks, resulting in spontaneous wound healing without requiring further surgical interventions. This case highlights the challenges of coordinating medical, surgical, and hematological treatments in such complex cases, necessitating effective communication and collaboration among multidisciplinary teams to optimize patient outcomes.

Bilateral sagittal split osteotomy is a commonly used, standard procedure in orthognathic surgery to correct malocclusion and jaw misalignment. Postoperative vascular complications are extremely rare and under-reported in the literature. This contribution presents the case of a 48-year-old male patient who underwent bilateral sagittal split osteotomy due to class II skeletal malocclusion. There were no abnormalities during the surgery. However, the patient developed facial palsy and experienced a pulse-synchronised murmur. Computed tomographic angiography (CTA) revealed an arteriovenous fistula between the right external carotid artery and the pterygoid plexus with pseudoaneurysm. Following the diagnosis, the patient was successfully treated with an intervention involving coiling and sealing with histoacrylic glue. It is crucial to be aware of serious vascular complications following orthognathic surgery, as a delay in diagnosis and treatment can lead to life-threatening bleeding or long-term damage. CTA is the most rapid and accurate method of confirming the diagnosis. If there is clinical suspicion, this examination should not be delayed, and the therapeutic approach should be determined on an interdisciplinary basis.

The anterior lumbar interbody fusion (ALIF) and lumbar disc arthroplasty (LDA) procedures are both commonly performed to improve the quality of life and pain in people with lower back pain. However, few recent studies have compared 30-day complications on a large scale. The objectives of this study were to compare the 30-day complications seen after ALIF and LDA and identify risk factors for these complications. The National Surgical Quality Improvement Program (NSQIP) database was queried between the years 2012–2021 (10 years in total) for records of patients who underwent either ALIF or LDA as a primary procedure. Patients in each group underwent a 1:1 propensity match for age, gender, BMI, ASA status, diabetes mellitus (DM), hypertension requiring medication, congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), inpatient/outpatient status, smoking status, and bleeding disorders. Bivariate and multivariate analyses were performed to determine significant differences in complications and risk factors between these cohorts. A total of 1218 propensity-matched subjects, with 609 receiving ALIF and 609 receiving LDA, were included in the analyses of this study. The incidence of extended length of stay (LOS) (>4 days) was higher in the ALIF cohort compared to the LDA cohort (14.6% vs. 4.76%, p < 0.001). Multivariate analysis demonstrated that subjects who underwent LDA had lower odds (Odds Ratio [OR]: 0.457; 95% Confidence Interval [CI]: 0.283–0.738, p = 0.001) of experiencing extended LOS compared to the ALIF cohort. Longer operative times increased the odds of prolonged LOS in both cohorts. The results of this study suggest that ALIF is associated with longer LOS than LDA when baseline demographic data are controlled. Further, longer operative times increase the odds that subjects receiving either ALIF or LDA will experience a prolonged LOS. Besides extended LOS, ALIF and LDA produce a relatively similar 30-day complication profile.

In this study, we describe a case of graft dislocation into the vitreous cavity after Descemet stripping automated endothelial keratoplasty (DSAEK), and review the risk factors and complications of posterior dislocation. A 70-year-old female with disruption of the iris–lens diaphragm experienced DSAEK graft dislocation into the vitreous cavity during air re-bubbling at 1 week postoperatively. The corneal opacity hindered adequate visualization of the vitreous cavity for the immediate retrieval of the graft. Five days after re-bubbling, vitrectomy and corneal tissue removal was performed using a temporary Eckardt keratoprosthesis, and penetrating keratoplasty was subsequently performed. Two weeks after graft removal, a retinal detachment occurred. Silicon oil was used as a tamponade to reattach the retina. Three months after the last procedure, the retina was attached, and the cornea was clear. Posterior dislocation of DSAEK graft is a rare complication. A disrupted iris–lens diaphragm and previous vitrectomy are the main risk factors. Severe vision loss is more likely to occur when corneal tissue removal is delayed. In cases of delayed removal, it is advisable to take precautions to prevent possible retinal detachment.

This retrospective study compares the clinical outcomes of the Minimally Invasive Reduction and Osteosynthesis System (MIROS) and intramedullary nailing (IMN) in treating isolated surgical neck fractures of the humerus. A total of 42 patients were included, with 18 treated using MIROS and 24 with IMN. The primary outcomes assessed were the complication rates, functional recovery (DASH score), pain levels (VAS), and radiological healing. The MIROS group exhibited a higher complication rate (22.2% vs. 8.8%), with K-wire migration and superficial infections being the most frequent. Patients treated with MIROS reported lower postoperative pain (VAS 45 ± 25.7) compared to the IMN group (VAS 58.1 ± 12.5). Both groups demonstrated radiological healing within three months, but one MIROS patient required reoperation due to hardware failure. No significant differences were observed in the DASH scores between the groups. Our findings suggest that IMN is a preferable treatment option for younger patients with good bone quality, while MIROS may still be beneficial for elderly patients with significant comorbidities, albeit with a higher risk of complications. Future prospective studies are recommended to confirm these findings.

Chylothorax is a rare complication occurring after cardio-thoracic surgical procedures. This condition presents challenges for diagnosis and treatment. Operative ductal ligation is the method of choice for relapsing or refractory cases, and it can be performed through the aid of IGC injection for the identification of chylous leakage. Our report presents the use of ICG fluorescence during VATS to successfully identify and treat a left-sided post-surgical chylothorax. The patient underwent a pulmonary wedge resection for a suspect malignant lesion and developed chylous leakage in the early postoperative period. On postoperative day 7, the patient underwent a revision thoracoscopy for hemostasis and thoracic duct ligation. ICG injections were performed through bilateral inguinal lymph nodes and approximately 15 min after we performed the re-thoracoscopy with effective identification and ligation of the chyle leakage. ICG fluorescence-guided VATS is a valuable and effective method for managing postoperative chylothorax, especially for left-sided leaks.

(1) Background: The optimal management approach for adults with traumatic pneumothorax without haemothorax remains an area of debate. Specifically, there is lack of consensus as to whether insertion of a pigtail catheter is superior to a formal intercostal catheter in improving complication rates. (2) Methods: Medline, EMBASE, Cochrane Central, and the World Health Organisation International Clinical Trials Registry Platform databases were systematically searched for studies evaluating pigtail catheters compared to formal intercostal catheters for the management of traumatic pneumothorax. Investigative outcomes of interest included pain, duration management, failure, need for formal thoracoscopic surgery, need for supplemental oxygen, length of stay, infection and overall total complications. (3) Results: Three studies evaluating 280 patients were included in this analysis. There was no significant difference in total complications, rates of failure, length of stay or duration of management between pigtail catheters and formal intercostal catheters. This evidence was based on studies of low to moderate risk of bias with poor control for confounding factors. (4) Conclusions: This systematic review and meta-analysis demonstrates lack of evidence to suggest pigtail catheters are superior to formal intercostal catheter for traumatic pneumothorax. These findings may reflect a true absence of effect between either approach for this patient cohort or non-committal findings in light of limitations of the underlying evidence. Further prospective trials with larger sample sizes and control for confounders are required to validate the outcomes between these two modalities of treatment.

Title: The Impact of Social Media on Public Perception and Litigation in Hernia Surgery Complications. Introduction: Social media significantly impacts public perception of healthcare, leading to increased litigation for complications after hernia surgery. Our research focused on terms like ‘inguinal hernia repair,’ ‘medico-legal,’ ‘informed consent,’ ‘litigation,’ ‘malpractice,’ ‘social media’, ‘mesh’, ‘Leistenbruch’, and OLG in Pubmed, Google Scholar, and Google. Results showed chronic postoperative pain as a common cause of malpractice claims, with ultrasound being a valuable diagnostic tool. Urological injuries account for a significant portion of complications after surgery. Mesh infection leads to hospital readmission, increased healthcare costs, and lawsuits. The quality of the consent process is crucial, and patient perceptions of mesh use influence their decision-making. Healthcare professionals must understand the impact of social media on public perception and provide comprehensive patient information for informed consent and satisfaction.

Foreign body intestinal perforation is a critical and potentially life-threatening condition that presents significant diagnostic challenges, especially in rural populations who are often distant from healthcare facilities and lack access to necessary resources. In these settings, the surgical approach is further complicated by prolonged diagnostic times and delayed access to appropriate care. This article presents a series of cases involving patients with foreign body intestinal perforation of both vegetable and animal origin. Among these cases, one patient died due to delayed voluntary treatment, and another presented without leukocytosis, further complicating the diagnosis. Socioeconomic barriers made follow-up challenging in most cases, negatively impacting patient outcomes. This study details patient characteristics, surgical approaches, and outcomes. Community education, improved infrastructure, and greater awareness among healthcare providers are essential to improving outcomes, particularly in rural areas where healthcare delivery is more challenging and intensified efforts are required to enhance patient care and quality of life.

Percutaneous aortic valve replacement (TAVI) has become the treatment of choice for elderly patients with severe aortic valve stenosis because of its less invasive nature compared to surgery. As TAVI is increasingly offered, issues such as vascular lesions, access site problems, paravalvular leaks, and aortic dissection (AD) are a few associated complications, needing consideration. AD after TAVI is rare but serious, occurring in 0.2% to 0.3% of cases, with both intraprocedural and late cases reported. This case study concerns a 68-year-old woman who developed Stanford B AD, external iliac artery dissection, and right common femoral artery occlusion after TAVI. Treatment included the stenting of the iliac and common femoral arteries, followed by a staged procedure: debranching, thoracic endovascular aortic repair (TEVAR), and endovascular aneurysm repair (EVAR), with satisfactory results. This case underscores the importance of vigilance in the management of TAVI-related complications to optimize patient care and outcomes.

Background: Intestinal intussusception is defined as the invagination of one segment of the intestine into the lumen of an adjacent intestinal segment, resulting in the mechanical intestinal obstruction of multifactorial origin with a high risk of morbidity and mortality. It is a rare pathology in adults with a nonspecific clinical presentation. We present the case of a 26-year-old male patient who was admitted postoperatively after multiple extra institutional surgical interventions due to polytrauma secondary to a work-related accident that caused high-impact trauma by a solids mixer. However, he was referred to our institution due to suspected vascular trauma in the right femoral artery. During his hospital stay, he developed intolerance to oral intake associated with pain, abdominal distension, and persistent emetic episodes despite medical management. Consequently, an abdominal CT scan with double contrast was requested, revealing intestinal intussusception secondary to intestinal adhesions, which required new surgical management with a favorable resolution; Discussion: Intussusception in the adult population is rare and is primarily caused by an identifiable structural lesion. It is one of the most challenging pathologies in terms of diagnosis and management due to its nonspecific presentation. However, when postoperative symptoms indicating intestinal obstruction appear, a computed tomography scan is considered the imaging modality of choice for diagnosing intussusception in adults; Conclusions: The development of postoperative peritoneal adhesions is a common cause of intestinal obstruction that can lead to complications such as intestinal intussusception, requiring additional interventions. Therefore, it is vital to identify their presence to reduce morbidity and mortality.

Abdominal aortic aneurysms (AAAs) are a highly asymptomatic vascular pathology with an increasing risk of rupture, leading to high mortality. Upon detection, treatment primarily involves lifestyle changes to slow the growth rate. Aneurysm rupture requires immediate surgical intervention due to its high mortality. Endovascular aneurysm repair (EVAR) is a common treatment option, involving stent placement at the aneurysm site. However, the stent is a foreign body; therefore, it is susceptible to immune response and infection. This case series presents patients with infected endovascular stents following a diagnosis of abdominal infrarenal aortic aneurysm and EVAR. The patients’ follow-ups revealed varying prognoses, complications, and treatments post-infection. These findings are compared with outcomes reported in the medical literature. Preventing aortic stent graft infection through proper aseptic techniques is crucial. This practice reduces patient complications, shortens inpatient hospice stays, and, most importantly, enhances patient quality of life.

Background: Complications are an inevitable part of orthopaedic surgery, and how one defines complications can have an impact on the ability to learn from them. There have been issues with a commonly used classification system first outlined by Clavien and Dindo. Our aim was to evaluate a modification of this classification system developed for use in our department, with our hypothesis being that this could make our audit presentations more efficient. Methods: A modified Clavien–Dindo Classification was prospectively applied to all complications recorded in the orthopaedic departmental audits at our institution for a 12-month period. The audit discussion was recorded and analysed and compared with the complication audits for the preceding 12-month period. Results: We analysed eight audit presentations before and eight audit presentations after the introduction of a modified Clavien–Dindo classification to our orthopaedic complications over a 2-year period. The number of PowerPoint™ slides (103 vs. 84, p = 0.03) and the time spent on each presentation (88 vs. 71 min, p = 0.02) decreased significantly with the introduction of the modified classification. The novel system was found to have high inter-observer reliability. Conclusions: The modified Clavien–Dindo classification system is a reproducible classification system for orthopaedic complications. It made our audit presentations more efficient.

The reporting of surgical, interventional, and anesthesiologic complications is essential for improving the quality of healthcare delivery and for standardizing and reproducing outcomes data. To address underlying issues in the reporting of complications and adverse events, it may be necessary to provide education and training, establish standardized definitions and reporting requirements, and create incentives for healthcare providers to report complications. Complications, a new international peer-reviewed open access journal, aims to provide best practice and expert opinion recommendations on the prevention, diagnosis, pathogenesis, and management of complications in basic, translational, and clinical research, as well as epidemiology. The journal invites authors to address four components of perioperative adverse events: assessment, reporting, analysis of anticipatable factors, and management. The usability and practical implications of this information can have significant implications for academic and clinical practice. The prioritization of the assessment and reporting of adverse events to standardize their management and improve the understanding of the impact of these events on patients’ peri-operative course.
