Background: Major airway injuries, regardless of whether their aetiology is traumatic or iatrogenic, are rare but potentially fatal. In selected cases, surgery plays a key role; however, it has to be performed by highly experienced professionals in emergency settings. Methods: We reviewed all surgical procedures involving the trachea which were performed at our institution in the last 5 years (365 procedures). We report here our experiences with major airway injuries, both traumatic and iatrogenic (19 procedures). All patients, including individuals from within our hospital and from other peripheral centres, were treated in an emergency setting within 12 h of correct diagnosis. Results: The location and extent of tracheal lesions can be different in every patient. After a proper evaluation with CT scan and bronchoscopy, we approached all our cases of tracheal injuries with a cervicotomy, using, in some selected cases, an endoscopic camera to better visualise lesions that involved the carina. However, in extremely severe cases, such as one we report here, where multiple repair attempts fail and tissue viability is compromised, demolitive surgery by means of posterolateral thoracotomy may represent the only remaining therapeutic option. Conclusions: Surgery on tracheal injuries is complex, highly specialised, and time-dependent. In selected cases, it has to be performed quickly by highly qualified professionals after proper evaluation in an emergency setting. Every airway injury differs in its location, extent, aetiology, and clinical presentation, and there is no unanimous consensus on standardising treatment. Only high-volume centres with highly experienced professionals can guarantee correct management of this rare but life-threatening event. Full article

Obesity is a multifactorial disease linked to chronic inflammation, metabolic disorders, and gut microbiota dysbiosis. Bariatric surgery (BS) and endoscopic sleeve gastroplasty (ESG) are effective for sustained weight loss and comorbidity improvement but may cause gastrointestinal and nutritional complications. This narrative review, informed by a structured literature search, synthesizes evidence on gastrointestinal side effects, gut microbiota alterations, and nutritional management after BS and ESG. Literature searches in PubMed and Scopus, without time limits, included English full-text articles on postoperative symptoms, microbiota changes, and nutritional outcomes. Bariatric procedures (e.g., Roux-en-Y gastric bypass, sleeve gastrectomy) and ESG are associated with adverse events such as dumping syndrome, GERD, nausea, and micronutrient deficiencies. Surgery induces profound shifts in gut microbiota composition and diversity, contributing to improved metabolic regulation. ESG, though less invasive, produces comparable microbial changes with a favorable safety profile. Nutritional management—progressive diet protocols and supplementation—is critical for preventing deficiencies and sustaining outcomes. Mediterranean-style diets appear more sustainable than high-protein regimens. Study heterogeneity, small cohorts, and limited long-term ESG follow-up reduce generalizability. Multidisciplinary care integrating surgical or endoscopic approaches with personalized nutrition and microbiota modulation is essential to optimize outcomes in obesity management. Full article

Background: Anterior cruciate ligament reconstruction (ACLR), one of the most frequently performed orthopedic procedures, has experienced rising demand and escalating costs, driving efforts to reduce expenses through shorter hospital stays and an increased shift toward outpatient settings. This study aims to evaluate how differing definitions of “outpatient” surgery influence the interpretation of outcomes following ACLR. Methods: ACS-NSQIP was queried for patients undergoing primary ACL reconstruction between 2014 and 2023. Patients ≥ 18 years with CPT code 29888 were included. Patients with missing hospital length of stay (LOS) data or a LOS > 2 days (≥99th percentile) were excluded. Two definitions of “outpatient” surgery were evaluated: hospital-defined outpatient (HDO) and same-day discharge (SDD, LOS = 0). Propensity score matching of baseline demographics and comorbidities was used to compare HDO and SDD cohorts to their respective inpatient counterparts. Primary outcomes analyzed included 30-day readmission, reoperation, and postoperative complications. Univariate and multivariate analyses were performed to compare risks of complications for HDO and SDD cohorts compared to their inpatient counterparts. Results: A total of 37,546 patients were included in this study, with 35,334 HDO (94.1%) and 34,801 (92.7%) SDD cases. 1021 (2.9%) of the 35,334 HDO patients had an inpatient hospital stay of at least 1 night. In propensity-matched cohorts, hospital-defined inpatient ACLR was associated with significantly greater risk of 30-day reoperation (odds ratio [OR] 3.167, 95% CI 1.267–7.915, p = 0.009) and superficial surgical site infection (SSI) (OR 5.0, 95% CI 1.712–14.604 p = 0.001), while HDO ACLR was associated with increased risk of deep vein thrombosis (DVT) (OR 0.333, 95% CI 0.121–0.916, p = 0.025). Compared to the propensity-matched SDD cohort, inpatient ACLR was significantly associated with greater rates of 30-day readmission (OR 1.988, 95% CI 1.088–3.630, p < 0.001), reoperation (OR 3.222, 95% CI 1.528–6.794, p = 0.001), and superficial SSI (OR 3.286, 95% CI 1.412–7.644, p = 0.003). Conclusions: This study found differences in readmission and deep vein thrombosis between HDO and SDD cohorts when compared to inpatient ACLR. A standardized definition of outpatient surgery should be created to clearly distinguish same-day discharge from other outpatient categories, considering discharge timing and patient monitoring practices.

Background/Objectives: Cystocele remains a prevalent condition with high recurrence rates following conventional native tissue repair. While mesh-based techniques may reduce anatomical recurrence, they are associated with increased complications and regulatory limitations. Our study proposes a defect-oriented approach to cystocele repair to assess whether individualized surgical management based on defect type can improve outcomes, particularly recurrence rates. Methods: A single-center retrospective analysis of 317 women undergoing cystocele repair (2019–2020) was performed. Patients were classified into five groups according to defect type: lateral defect at level II, central defect at level II, apical defect, mixed apical and lateral defects at level II, and mixed apical and central defects at level II. Surgical techniques, including vaginal mesh repair, laparoscopic or pre-peritoneal Richardson repair, sacropexy, lateral suspension, and combined procedures, were tailored to the identified defect. Postoperative outcomes and recurrence rates were assessed during follow-up visits. Results: The most common defect was apical defect at level II (35.6%) followed by lateral defect (32.8%), mixed apical and lateral (17.7%), central (8.5%), and mixed apical and central (5.4%). The most frequent procedures were vaginal mesh repair (33.8%) and laparoscopic sacropexy (28.7%). In our cohort, the overall recurrence rate was 6.3%, with the highest recurrence observed in the central defect group (11.1%) and lowest in the mixed apical and lateral defect group (0%). Conclusions: A defect-oriented classification and individualized surgical approach for cystocele enables effective, durable repair with low recurrence rates. Precise identification of the anatomical defect, rather than the routine use of hysterectomy or mesh, should guide surgical planning to optimize functional and anatomical outcomes. Full article

Background/Objectives: Heel reconstruction is a complex procedure that requires soft tissue reconstruction resistant to weight, pressure, and shear stress. Various flap reconstruction methods have been reported; among them, free fasciocutaneous flaps have advantages in terms of function and aesthetics, but also have challenges due to the longer operation time required and the possibility of failure. The primary aim of this study was to examine the functional outcomes of heel reconstruction using free lateral arm fasciocutaneous flaps after wide excision of heel skin cancer. Methods: Between January 2014 and December 2020, eight patients underwent wide excision of skin cancer and reconstruction of the heel with a lateral arm free flap. Perioperative clinical data and postoperative outcomes, including flap survival, complications, Lower Extremity Functional Scale (LEFS) score, and American Orthopaedic Foot and Ankle Society scale (AOFAS) score, were analyzed from clinical records. Functional assessments were performed at a minimum of 12 months postoperatively (mean 18.3 months, range 12–24 months) by a single blinded examiner who was not involved in the surgical procedures. Both preoperative and postoperative LEFS and AOFAS scores were recorded for comparison. Results: The mean size of the skin and soft tissue defect was 32 cm², the mean duration of surgery was 179 (range: 160–215) minutes, and the mean duration of hospital stay after surgery was 17 (range: 14–19) days, with a mean follow-up period of 48 (range: 33–59) months. Among the eight patients, two had diabetes mellitus (25%), one had peripheral neuropathy (12.5%), and none had clinically significant peripheral vasculopathy. All flaps survived, with one congestive episode. Satisfactory aesthetic and functional results were observed in all patients. The mean preoperative LEFS score was 28 (SD ± 6.1), which improved significantly to a postoperative mean of 57 (SD ± 8.3). Similarly, the mean preoperative AOFAS score was 45 (SD ± 5.8), improving to a postoperative mean of 61 (SD ± 6.2). Minor donor site complications included hypertrophic scarring in two patients (25%) and transient sensory changes in the lateral arm region in three patients (38%), all of which resolved with conservative management. Conclusions: This research suggests that the lateral arm free flap can be considered a reliable option in heel reconstruction, resulting in acceptable functional and aesthetic outcomes. It provides excellent durability, with solid bony union and good contour in small to moderate-sized heel defect cases. Full article

Background/Objectives: Patient preoperative cardiorespiratory physical fitness measured by maximal oxygen consumption (VO2max) is highly relevant to postoperative outcomes, with low VO2max associated with a greater symptom burden and a greater prevalence of long-term treatment-related cardiovascular disease risk factors in patients undergoing surgery. A network meta-analysis (NMA) was conducted to determine the effects of different components of prehabilitation, including exercise, nutrition, psychological intervention, and different combinations of the aforementioned interventions, on oxygen consumption in people undergoing major abdominal or cardiothoracic surgery. Methods: A literature search was conducted from inception to December 2025. Randomized controlled trials on the effectiveness of prehabilitation programmes on pre-surgery VO2max were included. The risk of bias was assessed via the Cochrane risk of bias (RoB 2.0) tool, and the quality of evidence was assessed via the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) tool. Pairwise meta-analyses and NMAs were conducted for direct and indirect evidence. Results: Fourteen studies were included in this NMA. The highest effect (ES) for VO2max scores was for the exercise group versus the control group (ES: 0.44; 95% CI: 0.11, 0.78). When exercise was categorized according to intensity, the highest effect was for high-intensity interval training (HIIT) versus the control (ES: 0.51; 95% CI: 0.04, 0.97). Conclusions: Exercise HIIT should be considered the most effective strategy for improving exercise capacity in patients undergoing major abdominal or cardiothoracic surgery. Given the importance of VO2 as a predictor of morbidity, mortality, and the potential occurrence of adverse events after the procedure in surgical patients, it is essential to include its measurement in future studies to estimate both the risk of procedures and the effect of prehabilitation programmes.

Fractures of the posterior malleolus are key determinants of ankle stability and long-term functional outcome in complex ankle injuries. The posterolateral rim fragment represents a bony avulsion of the posterior syndesmotic complex. Anatomical reduction of this fragment restores the fibular incisura, posterior tibiotalar stability, and syndesmotic integrity. Based on a geriatric case of a trimalleolar ankle fracture with a Bartoníček type 2 posterior malleolar component, this review describes a modified minimally invasive inside-out fixation technique performed under intraoperative three-dimensional imaging. The posterior malleolar fragment was stabilized using a posterior-to-anterior headless double-threaded compression screw. The medial malleolus was fixed with two parallel partially threaded cannulated cancellous screws, and the distal fibular fracture was stabilized using a reamed intramedullary locking nail. The surgical technique, potential complications, and postoperative management are described in detail. This approach combines the biomechanical advantages of direct posterior malleolar fixation with minimal soft-tissue disruption, providing a stable and reliable construct for the treatment of complex ankle fractures, particularly in geriatric patients and in those with compromised soft-tissue conditions.

Intraoperative optical coherence tomography (iOCT) has emerged as a pivotal technology in anterior segment surgery, particularly in cases limited by corneal opacity, edema, or altered anatomy. By providing real-time, cross-sectional imaging, iOCT enables surgeons to visualize otherwise hidden structures and to perform critical intraocular maneuvers with greater precision and safety. Its integration into the surgical microscope allows continuous monitoring of tissue–instrument interaction, transforming traditionally “blind” procedures into image-guided interventions. This review highlights the role of iOCT in endothelial keratoplasty, deep anterior lamellar keratoplasty (DALK), management of acute corneal hydrops, synechiolysis, glaucoma drainage device implantation, and ocular trauma. In endothelial procedures, iOCT helps confirm Descemet membrane removal, graft orientation, and resolution of interface fluid. In DALK, it facilitates accurate cannula placement, stromal depth assessment, and evaluation of leucoma extension to guide surgical strategy. During hydrops management, iOCT supports precise air/gas injection and compression suture placement. Additionally, it enhances safety in synechiolysis, shunt implantation, and repair of traumatic corneal injuries. Full article

Background/Objectives: Unstable intertrochanteric femur fractures (IFFs) in geriatric patients are associated with high rates of morbidity and mortality due to poor bone quality, multiple comorbidities, and limited functional capacity. This study aimed to compare the clinical outcomes of cementless bipolar hemiarthroplasty (BHA) performed via a transtrochanteric approach and proximal femoral nailing (PFN) in elderly patients with unstable IFFs. Methods: This retrospective comparative study included 131 patients aged ≥70 years who underwent surgery for AO/OTA 31-A2 and 31-A3 unstable fractures between January 2021 and July 2025 were retrospectively reviewed. 64 patients received cementless BHA and 67 underwent PFN. Eligible patients were ambulatory prior to fracture (independently or with a cane/walker); patients with pathological fractures/malignancy, alternative procedures (cemented or posterolateral BHA, total hip arthroplasty, tumor prosthesis, or other osteosynthesis methods), incomplete records, or <6 months of follow-up were excluded. Demographics, perioperative variables, mechanical complications, revision requirement, time to mobilization, and 1- and 6-month mortality rates were analyzed. Primary outcomes were mortality and perioperative clinical parameters. Results: The two groups were comparable in age, sex, ASA scores, and fracture patterns. Intraoperative blood loss and transfusion requirements were significantly higher in the BHA group (both p < 0.001). Mobilization was observed earlier in patients treated with BHA (1 [1,2] vs. 3 [2,3] days; p < 0.001). Mechanical complications were more frequently observed after PFN, which was associated with a higher revision requirement (17.9% vs. 4.7%; p = 0.018). Operative time, hospital stay, and 1- and 6-month mortality rates showed no significant differences between the groups. Conclusions: In geriatric patients with unstable IFFs, cementless BHA performed via a transtrochanteric approach may be considered a viable surgical option with appropriate patient selection, taking into account its association with earlier mobilization and the observed mechanical complication profile. PFN offers advantages of reduced blood loss and lower transfusion needs. Surgical decision-making should be individualized based on fracture morphology, bone quality, and the patient’s overall medical condition. Given the heterogeneity of unstable fractures within the AO/OTA classification and the retrospective nature of the present study, larger, multicenter prospective investigations incorporating functional outcomes are warranted to further clarify optimal treatment strategies.

This study examined the consistency between clinical criteria, assigned priority level, and waiting time for elective hysterectomy, assessing whether higher priority translates into faster surgical access. We conducted a retrospective cohort study including 846 women who underwent the procedure between January 2018 and January 2024 at a public hospital in São Paulo, Brazil. The median waiting time was 6 months (IQR: 3–10), with wide variability ranging from 0.5 to 53 months. All components of the clinical score were associated with higher priority levels, demonstrating adequate discriminative ability to identify patients at greater clinical risk. However, assigned priority was not associated with shorter waiting times. Criteria reflecting greater clinical vulnerability, including duration of symptoms (β = +2.50 months), age (β = +1.00), and cardiovascular disease (β = +1.00), were paradoxically associated with longer waiting times, whereas anemia was the only factor associated with reduced waiting time (β = −1.00). These findings reveal a marked discrepancy between formal prioritization and actual surgical scheduling, underscoring the need for more objective and equity-oriented criteria in the management of surgical waiting lists.

Background: Advances in breast reconstruction have transformed the recovery pathway for women undergoing mastectomy. What was once viewed mainly as a cosmetic option is now recognized as part of modern oncologic care, restoring not only body image but also confidence and quality of life. Yet, surgeons still face the same central dilemma: choosing between implant-based (IBR) and autologous reconstruction (ABR), particularly when postmastectomy radiotherapy (PMRT) is planned. Methods: We reviewed major studies published between 2014 and 2024, combining evidence from observational cohorts and recent meta-analyses that together report on more than 60,000 reconstructed breasts. Outcomes of interest included surgical complications, reconstructive failure, BREAST-Q patient-reported domains, and the impact of PMRT on both techniques. Data were interpreted in light of contemporary reconstructive innovations such as prepectoral implants, acellular dermal matrices, and robotic or sensory-nerve–enhanced autologous procedures. Results: Autologous reconstruction generally provided higher satisfaction and better psychosocial and sexual well-being, particularly in patients who received PMRT. Implant-based reconstruction offered faster recovery and shorter hospitalization but was more vulnerable to capsular contracture and reconstructive loss after irradiation. Across all eligible cohorts, reconstruction—immediate or delayed—did not increase local recurrence or compromise overall survival when adjuvant therapy was delivered without delay. Conclusions: Both IBR and ABR are oncologically safe and contribute meaningfully to recovery after mastectomy. Future progress will depend on combining precise surgical execution with new technologies—prepectoral implant positioning, robotic flap harvest, and sensory nerve coaptation—to achieve durable, natural, and patient-centered reconstruction.

Background and Objectives: Infective endocarditis (IE) continues to represent a life-threatening clinical entity, particularly in patients with advanced involvement of the cardiac fibrous skeleton. This study was designed to determine the incidence and to evaluate both short- and long-term outcomes in patients undergoing complex surgical intervention necessitating patch reconstruction for extensive and destructive IE. Materials and Methods: Between January 2008 and December 2024, 678 patients underwent cardiac surgery for IE at University Hospital Frankfurt/Main. The primary endpoint was long-term survival; the secondary endpoint was freedom from reoperation. Results: Ninety-six patients (14%) required complex patch reconstruction, owing to the severe involvement of the cardiac fibrous skeleton. The median age was 68 years (interquartile range [IQR], 16.5 years). Forty-three patients underwent redo surgery following previous cardiac procedures. Abscess formation was identified in 88% of cases (n = 85). Infective endocarditis was predominantly left-sided in 97% of patients (n = 94). In 40 patients (41%), the aortomitral continuity or the left ventricular outflow tract (LVOT) was involved. Combined surgical procedures were performed in 85 patients (87.6%), including 19 commando or hemi-commando operations. Thirty-day mortality was 20% (n = 19). The estimated 5- and 10-year survival rates were 46.5 ± 5.5% and 26.1 ± 6.8%, respectively. Survival did not differ significantly between native and prosthetic valve endocarditis, nor between commando/hemi-commando procedures and cases with abscess formation but preserved aorto-mitral continuity. Conclusions: In industrialized countries, extensive IE with abscess formation or destruction of the cardiac skeleton is predominantly associated with Staphylococcus aureus. Patients undergoing commando or hemi-commando procedures do not experience inferior survival compared with other patients with extensive IE. No survival advantage was observed for native versus prosthetic valve IE in the presence of extensive abscess formation. Full article

Background/Objectives: Obesity imposes a significant and growing burden on healthcare systems worldwide. Bariatric surgery remains the most effective long-term treatment for morbid obesity, but its success depends heavily on the quality of perioperative management and institutional expertise. This study presents a comprehensive analysis of 14 years of bariatric surgical activity in a university-based Center of Excellence, emphasizing complication rates and safety outcomes. Methods: A cohort analysis was performed on a prospectively collected database including all bariatric procedures conducted between June 2012 and June 2025 in an Obesity Center, located in ‘Saint Spiridon’ Hospital’ in Iasi, Romania. Eligibility was determined according to the American Society for Metabolic and Bariatric Surgery (ASMBS) and International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) guidelines. All patients underwent standardized preoperative evaluation by a multidisciplinary team. Results: Over a 14-year period, 1010 patients underwent surgery and had a mean age of 39 years and 72% of them were females. A total of 68 patients (6.73%) experienced complications, including 28 (2.77%) within 30 days and 40 (3.96%) after first month. No postoperative fistulas or deaths were recorded during the entire study period. Conclusions: The long-term data from over one thousand consecutive bariatric cases confirm the high safety and effectiveness of a multidisciplinary, protocol-driven approach. The absence of postoperative fistulas and mortality underscores the value of institutional experience and standardized perioperative care. Full article

Head and neck cancer surgery has evolved from radical organ-sacrificing procedures to function-preserving approaches integrated within multidisciplinary frameworks. This comprehensive literature review, concentrating on studies from the past five years while incorporating relevant publications from the last three decades and landmark historical papers, examines the evolving role of surgery emphasizing diagnostic methodologies including comprehensive genomic profiling, validated imaging biomarkers, and their clinical integration for treatment selection and response prediction. Modern surgical practice demonstrates a paradigm shift toward precision medicine through validated diagnostic technologies. Comprehensive genomic profiling identifies clinically actionable alterations in over 90% of head and neck squamous cell carcinomas, with tumor mutational burden serving as a validated predictive biomarker for immunotherapy response. Programmed death-ligand 1 (PD-L1) combined positive score functions as a validated diagnostic biomarker for immunotherapy efficacy, demonstrating significant clinical benefit in biomarker-selected populations. Radiomics-based predictive models utilizing machine learning algorithms achieve diagnostic accuracies exceeding 85% for treatment response prediction when validated across independent cohorts. Quantitative ultrasound spectroscopy combined with magnetic resonance imaging radiomics demonstrates high sensitivity and specificity for radiation response prediction. Habitat imaging techniques characterizing tumor microenvironmental heterogeneity predict pathologic complete response to neoadjuvant chemoimmunotherapy with area under the curve values approaching 0.90 in validation studies. Integration of these diagnostic methodologies enables response-adaptive treatment strategies, with neoadjuvant chemotherapy facilitating mandibular preservation and adjuvant therapy omission in over half of human papillomavirus (HPV)-associated cases following surgical downstaging. Clinical validation of these diagnostic platforms enables accurate treatment response prediction and informed surgical decision-making, though standardization across institutions and demonstration of survival benefits through prospective trials remain essential for broader implementation.

Introduction: Malignant pericardial effusion (MPE) represents a relatively rare complication in various types of solid tumors. Its management is often challenging. One solution can be represented by surgical approaches, including a pericardio-peritoneal window (PPW), which allows draining the fluid into the abdominal cavity. The aim of this study is to investigate the efficacy and long-term outcomes of the PPW procedure as a definitive therapeutic strategy for MPE. Materials and methods: We retrospectively and prospectively observed pre-, peri-, and postoperative data of patients undergoing pericardio-peritoneal window creation from 2010 to December 2023 at the European Institute of Oncology (IEO), including the surgical procedures needed, total and specific postoperative complications, 30-day mortality rate, relapse rate, and the treatment of possible relapses. Results: A total of 44 consecutive patients underwent a pericardio-peritoneal window. In 28 patients (63.8%) PPW was associated with mono or bilateral videothoracoscopy for pleural biopsies/talc poudrage. In 23 cases, pre-operative percutaneous pericardial drainage (usually 1–2 days before surgery) was performed. No intraoperative deaths were observed. The 30-day mortality was 9% (four patients). We observed pericardial effusion recurrence in three patients at two months and in five patients at six months. In only two cases we treated this condition because of a pre-tamponade condition, treated by percutaneous pericardial drainage. The success rate of the PPW regarding pericardial relapse requiring further procedures was 95.5%. Conclusions: Patients presenting with a favorable short-term prognosis benefit from the pericardio-peritoneal window as a safe and effective method for resolving malignant pericardial effusion. Conversely, pericardial drainage is recommended as the most appropriate therapy for those with a less favorable prognosis. Full article
