Background: Intravenous vancomycin remains a key agent in the treatment of complex orthopedic infections, particularly those involving methicillin-resistant Staphylococcus aureus (MRSA). However, its use is associated with significant risks, most notably nephrotoxicity. Despite guideline recommendations, standardized dosing and monitoring protocols are often absent in orthopedic settings, leading to inconsistent therapeutic drug exposure and preventable adverse events. This study evaluated the clinical impact of implementing a structured standard operating procedure (SOP) for intravenous vancomycin therapy in orthopedic inpatients. Methods: We conducted a single-center, pre-post cohort study at a university orthopedic department. The intervention consisted of a standard operating procedure (SOP) for intravenous vancomycin therapy, which mandated weight-based loading doses, renal function-adjusted maintenance dosing, trough level monitoring, and defined dose adjustments. Patients treated before SOP implementation (n = 58) formed the control group; those treated under the SOP (n = 56) were prospectively included. The primary outcome was the incidence of vancomycin-associated acute kidney injury (VA-AKI) defined by KDIGO Stage 1 criteria. Secondary outcomes included therapeutic trough level attainment and infusion-related or ototoxic adverse events. Results: All patients in the post-SOP group received a loading dose (100% vs. 31% pre-SOP, p < 0.001). The range of measured vancomycin trough levels narrowed substantially after SOP implementation (7.1–36.2 mg/L vs. 4.0–80.0 mg/L). The proportion of patients reaching therapeutic trough levels increased, although this was not statistically significant. Most notably, VA-AKI occurred in 17.2% of patients in the control group, but in none of the patients after SOP implementation (0%, p = 0.0013). No cases of ototoxicity were observed in either group. Infusion-related reactions decreased after the implementation of the SOP, though not significantly. Conclusions: The introduction of a structured vancomycin protocol significantly reduced adverse drug events and improved dosing control in orthopedic inpatients. Incorporating such protocols into routine practice represents a feasible and effective strategy to strengthen antibiotic stewardship and clinical quality in surgical disciplines. Full article

The significant advances in the surgical and medical treatment of gynecological cancer have led to improved survival outcomes of several subgroups of patients that were until recently opted out of treatment plans. Surgical cytoreduction has evolved through advanced surgical complexity procedures and the need for critical care of gynecological cancer patients has increased. Despite that, however, articles focusing on the need of perioperative monitoring of these patients completely lack from the international literature; hence, recommendations are still lacking. Critical care may be offered in different types of facilities with specific indications. These include the post-anesthesia care unit (PACU), the high dependency unit (HDU) and the intensive care unit (ICU) which have discrete roles and should be used judiciously in order to avoid unnecessary increases in the hospitalization costs. In the present review we focus on the pathophysiological alterations that are expected in gynecological cancer patients undergoing surgical treatment, provide current evidence and discuss indications of hospitalization as well as discharge criteria from intensive care facilities.

Gingival recession is a common problem, particularly affecting oral health and esthetics, and its treatment involves surgical root coverage procedures. The aim of this narrative review is to evaluate the role of systemic antibiotic therapy in mucogingival surgery for recession treatment. The available literature does not support routine antibiotic use in systemically healthy patients undergoing recession coverage surgery. Indications for prophylactic antibiotics are restricted to individuals at high risk of infective endocarditis and immunocompromised patients with elevated susceptibility to surgical site infections. Although mucogingival surgeries are performed in a non-sterile environment, the risk of infection remains low when proper aseptic techniques and good preoperative tissue preparation are applied. The review emphasizes the importance of making clinical decisions that consider the patient’s health status and are aligned with current recommendations. It also emphasizes the necessity for prospective studies to evaluate antibiotics’ effect on recession coverage procedures outcome. To bridge the gap between contemporary evidence and clinical practice and to foster responsible use of antibiotics in periodontal plastic surgery, the authors of this review integrate current evidence and clinical guidelines into a practical tool designed to assist clinicians in making reasoned, evidence-based decisions.

Background/Objectives: Upper tract urothelial carcinoma (UTUC) is a rare and biologically distinct subset of urothelial malignancies, comprising approximately 5–10% of urothelial cancers. UTUC presents unique diagnostic and therapeutic challenges, with both a higher likelihood of invasive disease at presentation and a less favorable prognosis compared to urothelial carcinoma of the bladder. Current treatment strategies for UTUC are largely derived from bladder cancer studies, underscoring the need for UTUC-directed research. This review provides a comprehensive overview of UTUC, encompassing diagnostic approaches, systemic and intraluminal therapies, surgical management, and future directions. Methods: A narrative review was conducted synthesizing evidence from guideline-based recommendations, retrospective and prospective clinical studies, and ongoing trials focused on UTUC. Results: Neoadjuvant cisplatin-based chemotherapy is increasingly preferred in UTUC due to the risk of postoperative renal impairment that may preclude adjuvant cisplatin use. Surgical management includes kidney-sparing approaches and radical nephroureterectomy (RNU), with selection guided by tumor risk and patient comorbidities. While endoscopic management (EM) preserves renal function, it carries a higher recurrence and surveillance burden; RNU remains standard for high-risk cases. Systemic therapy for advanced and metastatic UTUC mirrors that of bladder urothelial carcinoma. Enfortumab vedotin (EV) plus pembrolizumab showed superior efficacy over chemotherapy in the EV-302 trial, with improved response rate, progression-free survival, and overall survival across subgroups, including UTUC. For patients ineligible for EV, the CheckMate-901 study supported first-line chemoimmunotherapy with gemcitabine, cisplatin, and nivolumab. Further systemic therapy strategies include maintenance avelumab post-chemotherapy (JAVELIN Bladder 100), targeted therapies such as erdafitinib (THOR trial), and trastuzumab deruxtecan (DESTINY-PanTumor02) in FGFR2/3-altered and HER2-positive disease, respectively. Conclusions: Historically, the therapeutic landscape of UTUC has been extrapolated from bladder cancer; however, ongoing research specific to UTUC is deriving more precise regimens involving the use of immune checkpoint inhibitors, antibody–drug conjugates, and biomarker-driven therapies.

Background/Objectives: Surgical treatment is generally recommended for adolescent idiopathic scoliosis (AIS) when the Cobb angle exceeds 50 degrees even after skeletal maturity or 40 degrees with remaining growth potential. However, limited evidence exists regarding the natural history of curves between 40 and 50 degrees during the late stage of skeletal growth. This study aimed to evaluate the curve progression in AIS patients with a curve between 40 and 50 degrees at Risser stage IV or V. Methods: The inclusion criteria were as follows: (1) AIS patients at the late stage of skeletal growth (Risser IV or V) and a (2) curve between 40 and 50 degrees, with a minimum follow-up of 5 years. Sex, age, the magnitude of the curve, the location of the apex, Risser stage, height, and weight were measured at the baseline and the final follow-up. Curve progression was defined as an increase in the Cobb angle of ≥5 degrees. Patients were also categorized based on whether their final Cobb angle was <50 or ≥50 degrees to evaluate additional risk factors. Results: A total of 97 patients were included, with a mean follow-up of 97 months. Their mean age was 14.6 years at the baseline and 22.6 years at the final follow-up. The mean Cobb angle increased from 42.6 to 45.1 degrees, with a mean change of 2.7 degrees and an annual progression rate of 0.35 degrees. Curve progression was observed in 38 patients (39.2%), and 24 patients (24.7%) reached a final Cobb angle ≥ 50 degrees. Younger age (p = 0.004) and Risser stage IV (p = 0.014) were significantly associated with curve progression. In patients with a final Cobb angle ≥ 50 degrees, Risser stage IV (p = 0.050) and a larger baseline curve magnitude (p = 0.045) were also significant risk factors. Conclusions: In AIS patients at the late stage of skeletal growth, 39.2% experienced significant curve progression. A younger age and Risser stage IV were identified as risk factors for curve progression. A larger baseline curve magnitude and Risser stage IV were also associated with a final Cobb angle ≥ 50 degrees. Full article

Background/Objectives: Prehabilitation is a multimodal intervention introduced in preparation for various surgical procedures. The most effective treatment for obesity is bariatric surgery. Physiotherapy during prehabilitation for bariatric surgery may be an effective method of functional capacity improvement. We aimed to evaluate the impact of an individual outpatient 12-week, exercise-based physiotherapy program featuring prehabilitation on functional status, exercise tolerance, everyday mobility, and fatigue among patients qualified for bariatric surgery. Methods: The completion of an individual outpatient 12-week, exercise-based physiotherapy program during prehabilitation was an inclusion criterion for the study group. Participants included in the study and control groups were assessed twice, after enrollment into the prehabilitation program (the first assessment) and after prehabilitation but before surgery (the second assessment). Both assessments involved functional tests (a six-minute walking test [6MWT], a timed up and go test [TUG], a chest mobility test, anthropometric measures, a mobility index [Barthel], and a modified Borg scale). The collected anthropometric data and values from the 6MWT were used to create original linear models. This study followed STROBE recommendations. Results: The study group and control group did not differ statistically in terms of their anthropometric data. Statistically significant results were obtained between the first and second assessments in both groups in terms of body weight and waist circumference. However, only the study group showed improved results in the TUG test (p = 0.0001) and distance in the 6MWT (p = 0.0005). The study group presented with the normalization of blood pressure (BP) after exertion in the second assessment (systolic BP p = 0.0204; diastolic BP p = 0.0377), and the 6MWT results were close to the norms. According to the original linear model used to predict performance in the 6MWT, the primary modifiable determinant of exercise tolerance was the participant’s weight, while gender served as a non-modifiable determinant. Conclusions: Exercise-based physiotherapy in prehabilitation was associated with improved functional capacity in patients preparing for bariatric surgery, contributing to the improvement in 6MWT results in relation to the norms as well as exercise tolerance. Body weight may be an independent factor determining distance in the 6MWT for patients undergoing prehabilitation for bariatric surgery. Full article

Although platelets have been traditionally thought of to be essential hemostasis mediators, new research shows how important they are for controlling cellular oxidative stress, inflammatory processes, and immunological responses—particularly during major surgery on the abdomen. Perioperative problems are largely caused by the continually changing interaction of inflammatory cytokines, the formation of reactive oxygen species (ROS), and platelet activation. The purpose of this review is to summarize the most recent data regarding the complex function of platelets in abdominal surgery, with an emphasis on how they interact with inflammation and oxidative stress, and to investigate the impact on postoperative therapy and subsequent studies. Recent study data on platelet biology, redox signals, surgical stress, and antiplatelet tactics was reviewed in a systematic manner. Novel tailored therapies, perioperative antiplatelet medication, oxidative biomarkers of interest, and platelet-derived microscopic particles are important themes. In surgical procedures, oxidative stress dramatically increases the reactive capacity of platelets, spurring thromboinflammatory processes that affect cardiac attacks, infection risk, and recovery. A number of biomarkers, including soluble CD40L, thromboxane B2, and sNOX2-derived peptide, showed potential in forecasting results and tailored treatment. Antiplatelet medications are still essential for controlling risk factors for cardiovascular disease, yet using them during surgery necessitates carefully weighing the risks of thrombosis and bleeding. Biomarker-guided therapies, antioxidant adjuncts, and specific platelet inhibitors are examples of evolving tactics. In abdominal procedures, platelets strategically operate at the nexus of oxidative stress, inflammatory processes, and clotting. Improved patient classification, fewer problems, and the creation of individualized surgical care strategies could result from an increased incorporation of platelet-focused tests and therapies into perioperative processes. To improve clinical recommendations, subsequent studies may want to focus on randomized studies, biomarker verification, and using translational approaches. Full article

Despite being a rare malignancy, there have been several changes in the management paradigm for vulvar cancer. This review of the literature was undertaken to highlight key areas of treatment innovation and progress, including efforts to de-escalate morbid surgical resection as well as perform dose escalation of radiotherapy and incorporation of modern systemic agents to achieve better oncologic outcomes. There is still much debate regarding key high-risk pathology features and their corresponding prognostic significance and indications for adjuvant treatments. However, we are also developing a more nuanced understanding of the importance of precursor lesions and resultant subtypes of vulvar cancer, which suggests that there are more subtypes beyond the umbrella distinction of HPV status. Moving forward, we anticipate there will be an increasing number of trials investigating the triaging of management recommendations based on risk. Full article

Introduction: Liver transplantation remains the definitive treatment for end-stage liver disease but faces critical challenges including organ shortages and preservation difficulties, particularly with extended criteria donor (ECD) grafts. Hypothermic machine perfusion (HMP) represents a promising alternative to traditional static cold storage (SCS). Methods: This retrospective study analyzed outcomes from 62 liver transplant recipients between 2016 and 2025, comparing 8 grafts preserved by HMP using the Liver Assist^® system and 54 grafts preserved by SCS. Parameters assessed included postoperative complications, hemodynamic stability, ischemia times, and survival outcomes. Results: HMP significantly reduced surgical (0% vs. 75.9%, p = 0.01) and biliary complications (0% vs. 34.4%, p = 0.004), improved hemodynamic stability post-reperfusion (∆MAP%: 1 vs. 21, p = 0.006), and achieved superior one-year survival rates (100% vs. 84.4%). Despite longer ischemia periods, grafts treated with HMP exhibited fewer adverse effects from ischemia-reperfusion injury. Discussion: These findings highlight the substantial benefits of HMP, particularly in improving graft quality from marginal donors and reducing postoperative morbidity. Further adoption of this technology could significantly impact liver transplantation outcomes by expanding the viable donor pool. Conclusions: The study underscores the effectiveness of hypothermic machine perfusion (HMP) as a superior preservation method compared to traditional static cold storage (SCS), HMP appears to be associated with improved short-term outcomes in liver transplantation. By substantially reducing postoperative complications and enhancing graft viability, HMP emerges as a pivotal strategy for maximizing the use of marginal donor organs. Further research and broader clinical implementation are recommended to validate these promising results and to fully harness the potential of HMP in liver transplantation. Full article

Background: Several studies have suggested that laparoscopic peritoneal lavage for the treatment of diverticulitis might be associated with an increased event rate. The WSES (World Society of Emergency Surgery) guidelines recommend performing laparoscopic peritoneal lavage only in highly selected patients; however, selection criteria remain poorly described. This study, based on a single-center retrospective cohort of patients presenting with acute diverticulitis and undergoing surgery, aimed to assess the complication and long-term outcomes of the lavage group and to report our experience with the treatment of acute diverticulitis. Methods: Operative management of acute sigmoid diverticulitis was involved, in particular, laparoscopic peritoneal lavage, primary resection, and the Hartmann procedure. Results: Six-month follow-ups showed the occurrence of Clavien–Dindo complications in ≥2 in 21.9% of patients in the sigmoidectomy group versus 61.1% of patients in the lavage group (p = 0.0028). Among the 11 patients with complications after laparoscopic lavage, 9 required a second surgery. After a comparison between the patients with complications and those without who were managed with laparoscopic lavage, descriptive differences were found regarding the BMI (95% CI, 21.7–24.3 vs. 95% CI, 24.7–31.3, p = 0.0419). In analysis, a BMI of ≥27 kg/m² (OR, 16 p = 0.049) was associated with short- and long-term complications in the lavage group. There was no evidence for an association between complications and a BMI of ≥27 kg/m² in the primary resection (OR, 1.61 p = 1) or the Hartmann procedure group (OR, 4.25 p = 0.1438). Perforated colonic diverticulitis treated with laparoscopic peritoneal lavage was associated with a high morbidity rate. Conclusions: The choice of surgical strategy for acute diverticular pathology is complex, influenced by various conditions. BMI could be a prognostic factor for long-term outcomes, including recurrent diverticulitis and the occurrence of abscesses. Full article

Background: Mycobacterium ulcerans causes Buruli ulcer (BU), a necrotizing skin disease endemic in over 30 countries. Its toxin, mycolactone, drives tissue destruction, and the infection is transmitted via environmental reservoirs or vectors. Disease patterns vary globally, and an improved understanding of their pathogenesis may enhance current antimicrobial and surgical treatments. Methods: A comprehensive literature search from 1901 to 2025 was conducted across major databases to explore antimicrobial and reconstructive surgical strategies for Mycobacterium ulcerans. Search terms included BU, key antibiotics, and surgical interventions. Relevant English-language studies on treatment outcomes were reviewed to summarize evolving management trends and emerging therapeutic approaches. Results and Discussion: This review highlights the importance of early diagnosis and timely antimicrobial therapy in preventing disease progression and limb loss. It reviews WHO-recommended antibiotic regimens and discusses the theoretical risk of drug resistance, although clinical resistance remains rare and unreported in Australia. Surgical interventions in select cases are crucial, with timing being a significant factor in functional outcomes. The review also covers pediatric-specific challenges, including growth preservation and psychosocial support for young patients. Reconstructive options focus on limb salvage and staged reconstructions, with multidisciplinary care essential for optimal outcomes. The paper advocates for RCTs to refine treatment protocols, surgical guidelines, and explore emerging antibiotic therapies such as telacebec. Conclusions: BU remains a global health challenge, requiring early diagnosis, timely antimicrobial therapy, and surgery in selected cases. Future research will refine treatment and reduce long-term impacts. Full article

Background/Objectives: Acetabular fractures in older adults pose significant challenges due to bone fragility, complex fracture patterns, and increased comorbidities. Surgical management, including isolated open reduction and internal fixation (ORIF) and ORIF combined with acute total hip arthroplasty (THA) (combined hip procedure—CHP), have advanced considerably. Nevertheless, optimal postoperative rehabilitation and particularly weight-bearing (WB) recommendations remain controversial and inconsistent. This review aims to assess rehabilitation protocols, focusing on WB strategies following the surgical treatment of acetabular fractures in older adults. It also examines differences in WB restrictions by surgical technique (ORIF vs. CHP) and their impact on recovery, complications, reoperations, and mortality. Methods: A systematic review of PubMed, Embase, and the Cochrane Library (2006–2024) included studies involving patients aged ≥65 years treated surgically for displaced acetabular fractures. Data included WB protocols (full, partial, toe-touch), length of stay (LOS), healing, functional outcomes (mobility, Harris and Oxford Hip Scores), complications, reoperations, delayed THA, compliance, readmission, and mortality. Due to heterogeneity, findings were narratively synthesized. Risk of bias was assessed using ROBINS-I and RoB2. Results: Twenty studies involving 929 patients (530 isolated ORIF, 399 CHP) were analyzed. The overall mean follow-up was 3.5 years (range: 1–5.25 years). Postoperative WB protocols were reported in 19 studies (95%). Immediate full WB was permitted in 0% of isolated ORIF studies (0/13), with partial WB recommended by 62% (8/13) for durations typically between 6 and 12 weeks. On the other hand, immediate full WB was allowed in 53% (9/17) of CHP studies. Functional outcomes were moderate following isolated ORIF (mean HHS: 63–82 points), with delayed THA conversion rates ranging from 16.5% to 45%. CHP demonstrated superior functional outcomes (mean HHS: 70–92 points), earlier independent ambulation, and higher patient satisfaction (74–90%), yet increased orthopedic complications, including dislocations (8–11%) and implant loosening (up to 18%). LOS varied from 12 to 21 days (mean 16 days) for isolated ORIF and from 8 to 25 days (mean 17 days) for CHP. Readmission within 30 days was not explicitly reported in any study. Mortality at 1 year varied significantly (ORIF: 0–25%; CHP: 0–14%), increasing markedly at long-term follow-up (up to 42% ORIF, up to 70% CHP at five years). Compliance with WB restrictions was monitored in only two studies (11%). Conclusions: Postoperative rehabilitation after acetabular fracture surgery in older adults remains inconsistent and lacks standardization. Combining ORIF with acute THA may enable earlier weight-bearing and improved short-term function but carries risks such as dislocation and implant loosening. In contrast, isolated ORIF avoids these implant-related complications but often requires prolonged weight-bearing restrictions. Robust evidence is still missing. Future trials are essential to establish standardized protocols that balance mechanical protection and functional recovery. Full article

Background: Infective endocarditis after transcatheter aortic valve replacement (TAVR-IE) is a rare but severe complication associated with high morbidity and mortality. The optimal treatment strategy—surgical explantation versus medical therapy—remains uncertain, particularly given the technical demands of TAVR removal and the advanced age of many affected patients. Methods: We conducted a systematic review and meta-analysis of studies comparing the surgical and medical management of TAVR-IE. Primary outcomes included 30-day mortality and 1-year survival. Secondary analyses explored microbiological profiles, patient demographics, prosthesis type, postoperative complications, and surgical indications. A qualitative synthesis of surgical explantation techniques and reconstructive strategies was also performed based on recent consensus recommendations. Results: Three studies comprising 1557 patients with TAVR-IE were included; 155 (10.0%) underwent surgical treatment. Thirty-day mortality was comparable between groups (surgical: 9.7%; medical: 8.4%), while the pooled odds ratio for one-year survival did not reach statistical significance (OR: 1.91, 95% CI: 0.36–10.22; I² = 88%). However, single-center outcomes demonstrated markedly improved survival with surgery (96% vs. 51%). The most common surgical indications included severe valvular dysfunction (50.3%), aortic root abscess (26.5%), and large vegetations (21.3%), in line with current guideline recommendations. Postoperative complications included acute renal failure (10%) and longer hospitalizations (19.8 vs. 18 days), although these were not statistically different. Contemporary explant strategies—such as the Double Kocher, Tourniquet, and Y-incision aortic enlargement techniques—were highlighted as critical tools for surgical success. Conclusions: While underutilized, surgical intervention for TAVR-IE may offer significant survival benefits in select patients, particularly when guided by established indications and performed at high-volume centers. Outcomes depend heavily on timing, surgical expertise, and appropriate patient selection. As TAVR expands to younger populations, TAVR-IE will become increasingly relevant, necessitating early multidisciplinary involvement and broader familiarity with advanced explant techniques among cardiac surgeons.

The recommended treatment for early-stage cervical cancer (FIGO 2018 stages IA–IB2 and selected IIA1) is surgery, followed by either observation or adjuvant therapy, based on individual risk factors. Surgical management has evolved from extensive radical procedures to more conservative strategies, allowing for fertility-preserving options in appropriately selected patients. In 2018, a landmark study (LACC trial) evaluated the surgical approach to radical hysterectomy, comparing open vs. minimally invasive surgery. The results demonstrated that minimally invasive surgery was associated with worse disease-free and overall survival, leading to guidelines changes that recommend the open radical hysterectomy as the new standard of care. More recently, results from the prospective randomized SHAPE trial demonstrated that in well-selected patients with low-risk early-stage cervical cancer, recurrence rates are comparable between simple hysterectomy and radical hysterectomy. An ongoing study, the CONTESSA trial, is evaluating the role of neoadjuvant chemotherapy in the setting of fertility preservation for lesions measuring 2–4 cm. In addition, ongoing studies are evaluating different surgical approaches for both simple hysterectomy (LASH trial) and radical hysterectomy (ROCC/GOG-3043 and RACC trials), with a focus on comparing oncologic outcomes. Attention has also turned to refining lymph node assessment. Sentinel lymph node biopsy has become a standard staging strategy with reduced morbidity. The SENTICOL I-II and SENTIX/ENGOT-Cx2 trials support its safety and diagnostic accuracy in early-stage disease. This article offers a comprehensive overview of recently published prospective trials that have shaped clinical practice in the management of early-stage cervical cancer. It focuses on surgical approaches and radicality, the role of sentinel lymph node mapping, and fertility-sparing treatments. The review further draws attention to ongoing investigations and novel studies that may influence future directions in the field. Full article

Current guidelines recommend either radical prostatectomy (RP) or radiation with androgen deprivation therapy (ADT) for unfavorable intermediate- or high-risk prostate cancer. There has been emerging interest in the potential benefits of neoadjuvant ADT prior to RP for this population. Past trials indicate neoadjuvant ADT may be associated with reduced surgical complexity, pathologic downstaging, decreased positive margins, and decreased rates of nodal positivity, although they have not shown benefits for cancer progression and survival. Accordingly, neoadjuvant ADT is currently not recommended for surgical patients. Conversely, ADT is a mainstay of treatment in metastatic disease, and interest remains in expanding its use towards patients with clinically localized disease. There are several ongoing trials of second-generation androgen blockers such as enzalutamide, darolutamide, radiopharmaceuticals, and poly (ADP-ribose) polymerase (PARP) inhibitors to explore long-term cancer-specific survival benefits with neoadjuvant use. In this narrative review, we provide a comprehensive overview of the recent literature and ongoing efforts to incorporate neoadjuvant therapy for clinically localized prostate cancer patients who are at high-risk of recurrence after prostatectomy.
