Understanding the molecular subtypes of cholangiocarcinoma (CCA) is crucial for optimizing surgical decisions and patient outcomes. CCA shows significant heterogeneity, with distinct genomic profiles linked to tumor location—this may affect surgical approach. Intrahepatic CCAs frequently harbor targetable mutations like FGFR2 fusions and IDH1/2 mutations, offering new avenues for therapy. Surgeons can enhance patient selection based […]

CYP2A6 Genotypes Affect Survival in Pancreatic Cancer Patients
Decreased-function CYP2A6 genotypes correlate with worse outcomes for pancreatic cancer patients on S-1 therapy. 56.6% of patients had decreased-function genotypes, increasing lymph node metastasis (78% vs. 52.4%, p=0.001). Median recurrence-free survival was significantly shorter for poor metabolizers (19.2 months vs. 32.3 months, p=0.040). Understanding genotype impact may guide treatment personalization and improve patient outcomes. Poor […]
Intraoperative Cholangiography Use Doesn’t Lower Bile Duct Injury
Surgeons should know that increased use of intraoperative cholangiography (IOC) during cholecystectomy does not reduce bile duct injury rates, but it does lead to more postoperative ERCP procedures. Among 434,696 patients, BDI rates were low and similar across IOC use groups (0.5% for never, 0.4% for selective, and 0.4% for routine). Postoperative ERCP rates increased […]
Innovative Left-Sided Approach Improves Robotic Pancreatoduodenectomy
A left-sided uncinate-first method enhances surgical precision in complex robotic pancreatoduodenectomies. It provides better access to the superior mesenteric artery, especially beneficial for morbidly obese patients or those with bulky tumors. The technique allows for earlier vascular control and reduces traction on the superior mesenteric vein. This approach could become essential in cases where traditional […]
Fragility of NCCN Guidelines for Gastric Cancer Treatment
Recent analysis reveals significant concerns in the quality of evidence supporting NCCN guidelines for gastric cancer treatment. Only 40% of 30 randomized trials (13,765 patients) reported statistically significant outcomes, with a median fragility index of just 6. Adjuvant chemotherapy trials had the highest fragility index at 20, raising questions on their reliability. Surgeons should be […]
Female Patients Need More Surgical Information
Female patients undergoing ventral hernia repair report feeling less informed than males, which can affect their outcomes. 14.4% of females felt unprepared for surgery compared to 8.9% of males. 39.1% of females expressed anxiety about postoperative emotions versus 21.7% of males. 33.6% of females had concerns about recovery compared to 21.7% of males. Consider adjusting […]
Stent Choice in Biliary Drainage for Pancreatic Cancer: No Survival Advantage
Surgeons need to know that plastic and metal stents show similar long-term outcomes in patients with pancreatic ductal adenocarcinoma undergoing preoperative biliary drainage. Among over 6,500 patients, overall survival and recurrence-free survival were not significantly different between plastic and metal stents. Postoperative complications also showed no significant differences between stent types. Stent selection should be […]
Extrahepatic Bile Duct Resection Falls Short for Cholangiocarcinoma
Extrahepatic bile duct resection shows lower complications but worse survival compared to pancreaticoduodenectomy in early-stage cholangiocarcinoma. Major complications: 5.9% for bile duct resection vs 45.3% for pancreaticoduodenectomy (p < .01) Length of stay: 11 days for bile duct resection vs 25 days for pancreaticoduodenectomy (p < .01) 5-year overall survival: 38.9% with bile duct resection […]
AI System Accurately Triages Ostomy Photos from Patients
An AI pipeline effectively categorizes patient-submitted ostomy photos, improving triage efficiency. 43.9% of 538 images were deemed to have obstructed views, while 5.6% were healthy. The best model, Clip-ViT, achieved an impressive area under the curve of 0.99 and precision of 0.87. This technology has potential to streamline post-operative care by prioritizing cases requiring in-person […]
New models enhance surgical skill training
Biotissue models improve psychomotor skills for abdominal surgery training, crucial for surgical proficiency. Repeated practice with biotissue models cut operative time by 7.5 minutes (p < 0.0001). Objective skill assessment scores (OSATS) increased by 4.41 points (p < 0.0001). Incorporating these models into training curricula could offer an effective and budget-friendly solution for laparoscopic and […]
