A new reporting checklist improves how surgical prehabilitation studies are conducted and evaluated, enhancing outcomes for patients. The checklist has 40 items: 16 essential and 24 important for clear reporting. It covers intervention components, delivery methods, adherence, and outcomes. Adopting these standards will boost transparency in prehabilitation trials, leading to better reproducibility and clinical application. […]

Radiological Organ Invasion Signals Poor Outcomes in Pancreatic Cancer
Radiological adjacent organ invasion in resectable left-sided pancreatic cancer indicates worse prognosis and may alter treatment strategies. Patients with adjacent organ invasion had median survival of 25.9 months versus 67.2 months for those without (p < 0.001). Elevated CA19-9 levels (≥279 U/ml) and positive peritoneal cytology were significantly more common in the invasion group. Consider […]
High Concordance of cfDNA and Tumor Profiling in Appendiceal Cancer
This study shows that circulating tumor DNA (ctDNA) can accurately reflect the genetic profile of appendiceal cancer, which is crucial for surgical decision-making. ctDNA from plasma matched tumor genomic profiling with 98.4% concordance overall and 85.7% for actionable mutations. Key mutations found: KRAS (41%), GNAS (30%), TP53 (30%), and SMAD4 (29%). High-grade tumors are linked […]
Colorectal Cancer Liver Metastases Reveal Care Disparities
Surgical intervention for liver metastases in colorectal cancer is underutilized among disadvantaged groups, impacting outcomes. Only 18% of analyzed patients received hepatectomy or ablation, with non-Hispanic Black and Hispanic/Latino patients 17% less likely to undergo intervention. Patients at academic centers were 2.24 times more likely to receive surgical treatment than those at community programs. Higher […]
Minimally Invasive Surgery Reduces Risks in Hepatectomy
Minimally invasive surgery (MIS) lowers surgical risks in both initial and repeat hepatectomies, crucial for improving patient outcomes. In initial hepatectomy patients, MIS is linked to a lower risk of postoperative morbidity. For repeat hepatectomies, each point increase in adhesion severity (TORAD v2.0) raises morbidity risk by 60%, while MIS reduces this risk significantly (odds […]
Ex-Vivo Porcine Model: A Game-Changer for Surgical Training
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 […]
