Colloid carcinoma (cc) is a rare but distinct subtype of pancreatic cancer, revealing favorable outcomes compared to tubular carcinoma (tc). CC accounts for 25% of invasive intraductal papillary mucinous neoplasms. Patients with cc were more often male (70%), and had a higher prevalence of steatorrhea (26%) and diabetes (44%). Median overall survival for cc is […]

3D Planning Cuts Complications in Laparoscopic Liver Surgery
3D-guided planning significantly enhances laparoscopic hepatectomy for complex liver tumors. Reduced intraoperative blood loss: 80 ml vs. 160 ml (p < 0.001). Lower bile leakage rate: 3.1% vs. 15.4% (p = 0.015) in matched pairs. Consider adopting 3D-assisted techniques for better outcomes in challenging cases. In special-segment cases, operative times were shorter: 180 min vs. […]
Lower diabetes risk with minimally invasive parenchyma-sparing surgery for pancreas tumors
Minimally invasive parenchyma-sparing pancreatectomy (mi-psp) decreases the risk of postoperative diabetes and exocrine insufficiency for benign pancreatic tumors. Only 9.8% of mi-psp patients developed new or worsening diabetes compared to 23% after standard minimally invasive pancreatectomy (mi-p). The 5-year cumulative incidence of new-onset diabetes was 26.7% for mi-psp vs. 38.9% for mi-p (p=0.008). Pancreatic exocrine […]
Liver Transplant Offers Hope for Colorectal Liver Metastases
Deceased donor liver transplantation (DDLT) improves survival for patients with unresectable colorectal liver metastases (CLM). Overall survival is impressive at 96.9% at one year and 84.8% at two years. Disease-free survival at one year is 62.7%; however, recurrence occurs in 42.9% of cases. Accurate patient selection is crucial; KRAS mutation significantly links to recurrence (p=0.01). […]
Timing of Necrosectomy in Infected Pancreatic Necrosis Matters
Immediate necrosectomy for infected walled-off pancreatic necrosis offers no advantages over an on-demand approach. Clinical success rates were similar: 92% (immediate) vs. 88% (on-demand), p = .5. On-demand patients required fewer necrosectomy sessions (1 vs. 2, p ≤ .01) and had fewer adverse events (24% vs. 40%, p = .2). This suggests that a selective […]
New Models for Predicting Hospital Choice in Pancreatic Surgery
Distance-only models fail to accurately predict where patients receive pancreaticoduodenectomy (PD). Accuracy: distance-only model (16.3%), distance + volume model (32.9%), comprehensive model (24.3%). Patients correctly predicted by volume models were more often from urban areas (74.7% vs. 61.0%) and had lower in-hospital mortality (1.3% vs. 3.3%). Surgeons need to consider additional factors beyond distance, like […]
Novel Laparoscopic Method for Bile Duct Resection in PBM
A retroperitoneal-first laparoscopic technique is promising for bile duct resection in pancreaticobiliary maljunction, improving surgical outcomes. Operative time was 480 minutes, with 210 minutes for the retroperitoneal approach and only 40 ml blood loss. Postoperative recovery was smooth; the patient was discharged on day 14 and remains recurrence-free after 3 years post-chemotherapy. This technique offers […]
Gallium-68 PET for Pancreatic Neuroendocrine Tumors: Limited Sensitivity
A study shows Gallium-68 DOTATATE PET has high specificity but low sensitivity in identifying lymph node metastases in pancreatic neuroendocrine tumors, affecting surgical decisions. Detected suspicious lymph nodes in 24% of cases; pathology confirmed involvement in 42%. Sensitivity was 46%, specificity 92%, with a positive predictive value of 81%. Consider it for preoperative evaluations, especially […]
AI-Driven Marker Improves Outcomes for Pancreatic Cancer Nonproducers
A new AI-derived tumor marker can enhance treatment response assessment in pancreatic cancer patients who do not produce elevated CA19-9. In a study of 121 patients, a 50% or more decline in the marker (e19-9) was linked to a 5-fold higher likelihood of completing neoadjuvant therapy and surgery. An e19-9 level below 100 significantly correlated […]
Occult Nodal Disease in Gallbladder Cancer: Critical Insights
Many gallbladder cancer patients thought to be node-negative actually show hidden nodal metastasis, impacting surgical outcomes. Of 187 patients, 33.1% classified as clinically node-negative had occult nodal disease upon final pathology. Key preoperative predictors included elevated CA19-9, systemic immune-inflammation index, and jaundice. Risk of occult nodal disease increases significantly with more elevated markers: from 17.1% […]
