Cover Story (view full-size image): Popliteal artery injuries following knee dislocations are rare but devastating, often leading to ischemia and potential limb loss if not promptly addressed. This review explores the artery’s unique anatomical vulnerability, the critical window for diagnosis, and the most effective treatment strategies. Advanced imaging techniques like CT angiography and Doppler ultrasound improve early detection, while surgical interventions such as bypass grafting and primary repair remain key to restoring perfusion. Delays in recognition or intervention worsen outcomes, especially in cases with multi-ligamentous damage. By analyzing the existing literature, we highlight the importance of standardized protocols to improve limb salvage rates and long-term recovery, bridging the gap between vascular and orthopedic management.

Background: Despite ongoing efforts to improve the pancreaticoduodenectomy technique and perioperative care, surgical site infection (SSI) remains a contributor to morbidity. Efforts to reduce SSI include the use of negative pressure wound therapy (NPWT), but studies and meta-analyses have been met with conflicting results. We aimed to provide an up-to-date large-scale cohort study to assess the impact of NPWT on SSIs. Methods: Utilizing the National Surgical Quality Improvement Program database, we included patients undergoing a pancreaticoduodenectomy between 2017 and 2021 and divided patients into the NPWT and non-NPWT cohorts. A bivariate analysis was performed to compare baseline characteristics and complication rates between the cohorts. Multivariate logistic regression analysis was performed to assess the independent effect of NPWT on 30-day serious complication, 30-day mortality, and the development of deep or superficial SSI. A priori sensitivity analyses were performed in high-risk and malignancy cohorts. Results: Of the 14,044 included patients, 1689 (12.0%) patients had a prophylactic NPWT device, while 12,355 (88.0%) did not. Patients were more likely to have NPWT if they had higher ASA scores, had diabetes, were dialysis-dependent, or had a hard pancreas, but they were less likely if they were a smoker, had steroid use, or had a bleeding disorder. Most complications occurred similarly between the two cohorts, including superficial and deep SSI, but NPWT patients had a longer length of stay (10.4 d vs. 9.5 d, p < 0.001) and higher organ space SSI (22.6% vs. 17.4%, p < 0.001). Following multivariable modeling to control for demographic differences, NPWT was not independently associated with a difference in likelihood of SSI (aOR 0.94, p = 0.691) or serious complications (aOR 0.958, p = 0.669). Furthermore, the sensitivity analyses of both high-risk and malignant subgroup also did not see an independent association of NPWT on the rate of SSI (aOR 0.98, p = 0.898 and 0.96, p = 0.788, respectively). Conclusion: NPWT is used infrequently and is not significantly associated with improved outcomes including in the high-risk or malignant subgroups based on multivariable analysis for surgical site infections nor did it improve the outcomes of 30-day serious complications in these subgroups. Considering this and other studies showing the limited benefit of NPWT in all-comers and in high-risk cohorts, it remains unclear whether NPWT offers benefits following PD. Full article

Background: Acute colonic pseudo-obstruction (ACP) is a life-threatening, rare condition of non-mechanical colon dilatation that can result in bowel ischaemia and perforation. The aetiology is relatively unknown but includes older age coupled with high comorbidity, decreased parasympathetic activity, certain medications, chemoradiotherapy and recent surgery. There are limited research data on ACP following reversal of ileostomy after ultra-low anterior resections (ULAR), thus this systematic review included cases from various types of bowel surgeries. Methods: A comprehensive literature search of relevant articles was conducted using the EMBASE, Medline, PubMed, Cochrane, and Scopus databases. Two cases of ACP following ileostomy reversal after ULAR for rectal cancer were also reported from the authors’ rural institution. This systematic review was conducted according to PRISMA 2020 guidelines. Results: A total of 522 studies were screened of which five case reports were included. Two case series (six patients) and the two patients from the authors’ rural institution developed ACP following reversal of ileostomy post-ULAR with potential causes being the > 6 months’ time from initial surgery to reversal causing prolonged colonic mucosal inflammation and reduced wall contractile strength. Anastomotic leak and chemoradiotherapy were other considerations. One of the rural patients developed right colon ischaemia and perforation needing urgent laparotomy, right hemicolectomy and formation of end ileostomy and mucous fistula. Conservative treatment included aperients, enemas, flatus tube, bedside or endoscopic decompression, and neostigmine. Conclusions: Early recognition is vital to treat ACP with medical therapy and decompression to prevent bowel ischaemia and perforation. Further research is needed to better characterise the aetiology, incidence and management strategies for this rare condition. Full article

Background: Patients with no-option chronic limb-threatening ischemia (NoCLTI), lacking suitable distal arteries for conventional revascularization, face major limb amputation. The 1-year mortality rate after major amputation is 48.3%, increasing to 70.9% in 3 years. Open deep venous arterialization (DVA) offers a promising alternative for limb salvage, achievable through open, endovascular, or hybrid approaches. We aim to provide a comprehensive, step-by-step guide to performing open DVA in NoCLTI patients, addressing preoperative and postoperative considerations as well as the technical details of the procedure. Methods: Patient selection for open DVA focuses on individuals with NoCLTI at high risk for amputation. Preoperative assessments include evaluating risk factors, determining limb threat severity using the Wound, Ischemia, and foot Infection (WIfI) score, and mapping anatomical patterns via the Global Limb Anatomic Staging System (GLASS). The procedure involves identifying the target artery using Doppler ultrasound, performing microdissection to expose the artery and vein, ligating proximal vein branches, and creating a side-to-side anastomosis. Venous valves are disrupted with a valvulotome to allow antegrade flow. A proximal bypass graft may be applied if necessary. Results: Postoperatively, patients are monitored for 2–4 days with frequent Doppler assessments. Anticoagulation therapy begins with a heparin drip, transitioning to oral agents and/or dual antiplatelet therapy. Wound care includes deferred debridement for 2–4 weeks and may involve negative-pressure therapy. Follow-up involves weekly visits for the first month, and then at 3 months, and every 6 months thereafter, with surveillance using transcutaneous oxygen measurement, the toe–brachial index, and arterial duplex ultrasound. Conclusions: Open DVA represents a viable limb salvage option for patients with NoCLTI, potentially avoiding major amputations and improving quality of life. Success depends on careful patient selection, a meticulous surgical technique, and comprehensive postoperative care. Full article

Cytoreductive surgery in the context of a multidisciplinary approach, including adjuvant and neoadjuvant therapy (when indicated), aims ideally to obtain complete resection and represents the cornerstone for long-term survival in patients with advanced ovarian cancer (AOC). Positive lymph nodes are a relatively frequent appearance during cytoreductive surgery for AOC and a widely accepted negative prognostic factor for long-term survival. However, the impact of systematic pelvic and paraaortic lymph node dissection (SPALND) on early and long-term outcomes in patients with cytoreductive surgery for AOC and no suspected positive lymph nodes remains highly controversial. The paper aims to review the relevant scientific literature exploring the role of SPALND in patients with AOC, focusing on peer-reviewed papers published before and after the LION study’s data release. The LION trial represents the only level 1 evidence study providing no scientific arguments for the routine using SPALND in AOC as part of complete cytoreductive surgery in patients without clinical suspicion of positive lymph nodes. The LION trial changed the practice of surgeons regarding SPALND, and current essential guidelines do not recommend it as a routine. Furthermore, SPALND may increase morbidity rates of cytoreductive surgery for AOC and negatively impact the patient’s quality of life. A comprehensive pelvic and paraaortic lymph node assessment is mandatory before and during cytoreductive surgery for AOC for proper disease staging, adequate management, and long-term prognosis. Further research is needed to identify patients with AOC at high risk for lymph node metastases; this group might benefit from SPALND. Full article

Background: Bronchial sleeve resection with complex reconstruction is a rare and intricate surgical procedure, particularly when addressing metastatic carcinoid tumors. This case report details the surgical management of a young male with a typical carcinoid tumor metastasized to the hilar and subcarinal lymph nodes. Case Presentation: A 28-year-old medically fit male presented with cough and occasional blood-tinged sputum for 2 months that was diagnosed to be due to a typical carcinoid tumor involving the left main bronchus, with metastasis to the hilar and subcarinal lymph nodes. The patient underwent a left bronchial sleeve resection with complex reconstruction of the left lower lobe bronchus. The reconstructed bronchus was then anastomosed to the main bronchus followed by hilar and subcarinal lymph nodes dissection. The surgical approach aimed to preserve lung parenchyma while ensuring complete tumor resection. Postoperative recovery was uneventful, with the patient demonstrating satisfactory respiratory function. Histopathological examination confirmed the complete resection of the carcinoid tumor and metastatic lymph nodes (hilar and inter-lobar LN (positive 2/5) and subcarinal LN (positive 1/6)). The patient had no signs of recurrence at the 3-month follow-up. Conclusions: This case highlights the feasibility and effectiveness of bronchial sleeve resection with bronchial reconstruction in managing metastatic carcinoid tumors. The successful outcome underscores the importance of meticulous surgical planning and execution in achieving favorable results in complex thoracic surgeries. Full article

Background/Objectives: Popliteal artery injury is a rare but devastating complication of knee dislocations, significantly increasing the risk of limb ischemia, amputation, and poor functional outcomes if not promptly managed. This systematic review primarily evaluates the functional outcomes associated with this injury but also reviews current research on diagnostic modalities and treatment strategies to provide a comprehensive understanding of this severe orthopedic and vascular injury. Methods: A systematic search of PubMed, in accordance with PRISMA Guidelines, identified 144 studies, of which 13 full-text articles were assessed for eligibility after excluding 131 during the title and abstract screening. Six studies were excluded due to missing vascular injury or functional outcome data or being written in a foreign language, leaving seven studies for inclusion. These studies were predominantly retrospective, focusing on knee dislocations with popliteal artery injury and reporting validated functional outcomes such as the Lysholm and International Knee Documentation Committee (IKDC) scores. The data were synthesized narratively due to heterogeneity in the study designs, interventions, and outcome reporting. Results: Patients with vascular injuries consistently demonstrated poorer functional outcomes compared to those without, with mean or median Lysholm and IKDC scores consistently being lower than non-vascular injury patients. Increased BMI, delayed intervention, and multi-ligamentous injury were associated with worse outcomes, highlighting the importance of timely surgical management. Early repair and grafting techniques improved functional recovery, while diagnostic modalities such as Doppler ultrasound and CT angiography showed high sensitivity in detecting vascular injury. Complications included limb ischemia, prolonged rehabilitation, and amputation, often linked to delayed diagnosis. Conclusions: Knee dislocations with popliteal artery injury require rapid diagnosis and early surgical intervention to optimize functional outcomes and reduce complications. Standardized outcome measures and high-quality prospective research are needed to refine management strategies and address patient-specific factors like BMI. Full article

Background: Anterior cervical discectomy and fusion (ACDF) is a common procedure for cervical radiculopathy and myelopathy. Severe obesity (BMI ≥ 40 or BMI ≥ 35 with comorbidities) is associated with increased perioperative risks. This study examines the impact of severe obesity on outcomes in patients undergoing single-level ACDF. Methods: Data from the Nationwide Inpatient Sample (2016–2019) were analyzed, including 85,585 patients who underwent single-level ACDF. Patients were classified as severely obese (n = 4935) or non-obese (n = 80,650). Outcomes such as length of stay, complications, and in-hospital mortality were compared using SPSS and MATLAB, with a significance level of p < 0.05. Results: Severely obese patients were younger (54 vs. 55.7 years, p < 0.001) and had more comorbidities like type 2 diabetes (38% vs. 17.8%, p < 0.001) and obstructive sleep apnea (31.1% vs. 9.5%, p < 0.001). They experienced longer hospital stays (1.92 vs. 1.65 days, p < 0.001) but similar in-hospital mortality (0.1%, p = 0.506). Severe obesity was linked to higher odds of complications, including increased risks of dehiscence (OR 8.2), respiratory failure (OR 6.5), myocardial infarction (OR 5.5), Horner syndrome (OR 4.7), pulmonary edema (OR 4.5), and dural tears (OR 4.1). Risks of acute kidney injury, pulmonary embolism, and dysphonia were also elevated in severely obese patients. Conclusion: Severe obesity is associated with higher complication rates and longer hospital stays following ACDF. Tailored perioperative management is essential to mitigate these risks and improve outcomes in this high-risk population. Full article
