This study validates a low-cost, ex vivo porcine model for surgical education with strong realism and reproducibility. Participants rated overall satisfaction at 5.0/5, with tissue quality at 4.9/5. Average harvesting and preparation times were 16.3 and 15.7 minutes, respectively. This model addresses ethical concerns and may enhance surgeon training outcomes while supporting the agri-food supply […]

Tissue Factor Levels Predict Survival in Pancreatic Cancer Surgery
High tissue factor (tf) expression in pancreatic cancer correlates with worse outcomes, offering a vital tool for patient selection. High tf was noted in 17.4% of cases, linked to elevated CA19-9 and shorter survival (median: 20.6 months vs. 38.8 months in low tf). It served as an independent poor prognosis predictor (hazard ratio: 2.21). Surgeons […]
Vasopressin’s Role in Edema Post-Liver Resection
Surgeons need to know that elevated vasopressin significantly contributes to fluid retention after liver resection, impacting postoperative management. Vasopressin (AVP) levels peaked immediately after major liver resections and stayed elevated through postoperative day 3, while aldosterone levels dropped by postoperative day 2. Patients showed greater short-term weight gain and decreased urine output during the AVP […]
Circular Staplers Show No Leak Rate Advantage in Colorectal Surgery
Using powered circular staplers in left-sided colorectal anastomoses does not significantly reduce anastomotic leaks compared to manual staplers. Analysis of 9 studies with over 3,100 patients found no significant difference in leak rates (RR 0.56) or morbidity (RR 0.84). However, powered staplers showed a significantly lower rate of post-operative bleeding (RR 0.20, p < 0.001). […]
Endoscopic Closure vs. Surgery for Colonic Perforations
Endoscopic closure may be a viable first-line approach for select iatrogenic colonic perforations. No difference in treatment success between endoscopic closure and surgery (RR 1.00, 95% CI 0.94-1.06). Endoscopy was generally used for smaller, immediately recognized injuries, while surgery was preferred for larger, delayed presentations. In ideal candidates (perforations <2 cm with no peritonitis), endoscopy […]
Whole-blood transfusion cuts mortality in civilian trauma cases
Whole-blood transfusion significantly reduces mortality in adult trauma patients compared to component therapy, especially in civilian settings. 24-hour mortality odds ratio for whole-blood vs. component therapy: 0.76 (95% CI, 0.60-0.95). Civilian data shows absolute risk reduction of 4.6% with whole-blood (n=39,028), and a 30-day mortality odds ratio of 0.76 (95% CI, 0.60-0.98). Surgeons should consider […]
National Mentorship Network Improves Support for Surgery Residents
A national mentorship network is addressing the significant mentorship gap for general surgery residents from marginalized backgrounds. More than one-third of surgery residents reported unmet mentorship needs; 68.2% enrolled in the program for this reason. 77.3% of residents met with their mentors, and 64.7% found them to be a good fit. This program may enhance […]
CT Imaging Predicts Early Recurrence in Liver Cancer
A new CT-based analysis effectively predicts early recurrence in hepatocellular carcinoma, offering surgeons a powerful tool for patient stratification. The nested habitats score achieved area under the curve values of 0.832, 0.896, and 0.833 across three cohorts, indicating strong predictive power. It remains an independent predictor of recurrence-free survival alongside other known factors like alkaline […]
PTCS Procedures Show High Success for Biliary Strictures
Percutaneous transhepatic cholangioscopy (PTCS) is effective for treating postoperative benign bilioenteric strictures and biliary stones. Initial anastomotic patency rates are 58.1% at 1 year and 41.9% at 2 years. Cumulative patency rates drop to 34.8% after 7 years but treatment success is high at 90.6%. These findings suggest PTCS should be a go-to for managing […]
Perioperative CEA Levels Predict Outcomes in Colorectal Cancer
Perioperative carcinoembryonic antigen (CEA) is a key marker for predicting survival and guiding treatment in stage II and III colorectal cancer. Elevated perioperative CEA is linked to worse overall survival (OS) and disease-free survival (DFS). Patients not receiving adjuvant chemotherapy with high CEA experienced significantly poorer outcomes; adjuvant therapy notably improved OS. Surgeons should consider […]
