Transduodenal ampullectomy (TDA) effectively diagnoses and treats unexplained dilation of the cholangiopancreatic duct (UDCD), demonstrating superior diagnostic rates compared to preoperative biopsies (78.41% vs. 65.94%). A study evaluated 203 patients and reported a postoperative complication rate of 27.07% with no mortality. Five-year survival rates varied significantly: 68.31% for adenocarcinoma, 85.99% for adenomas with high-grade dysplasia, […]

Video grading predicts bile leak risk in robotic surgeries
Bile leak rates post-robotic pancreatoduodenectomy are substantially reduced when surgical performance is graded. In a multicenter study of 259 patients, an objective structured assessment of technical skills (OSATS) score greater than 21 was linked to a 59.2% relative reduction in bile leaks, with rates decreasing from 12.5% to 5.1%. Additionally, a significant learning curve was […]
Intraoperative blood loss impacts morbidity after liver surgery
Among 2,491 patients undergoing liver cancer surgery, significant associations were found between adjusted blood loss (ABL) and postoperative complications. Patients with ABL below 8.5 ml/kg experienced a lower comprehensive complication index (CCI) of 10.6 compared to 15.2 in those with higher ABL (p < 0.001). A nonlinear correlation indicated CCI increases sharply beyond 10 ml/kg, […]
A predictive nomogram effectively identifies high-risk patients for cr-popf.
A novel nomogram utilizing preoperative factors has been developed to predict clinically relevant postoperative pancreatic fistula (cr-popf) following pancreaticoduodenectomy. The nomogram, based on 262 patient data, identified key risk factors such as triglycerides and pancreatic duct size. With an area under the curve of 0.812 during validation and strong calibration, it achieved sensitivities of 60.9% […]
Venous thromboembolism poses high mortality risk post-cancer surgery
A nationwide study found that 90-day postoperative venous thromboembolism rates were 6.1% for liver and 6.7% for pancreatic surgeries. Key risk factors included major hepatectomy, left pancreatectomy, obesity, and prior thromboembolism history. By one year, pancreatic surgery patients had a significantly higher cumulative incidence (9.8%) compared to liver surgery patients (7.0%). Patients experiencing venous thromboembolism […]
Machine learning predicts early recurrence risk in cholangiocarcinoma
A novel machine learning model effectively predicts very early recurrence (VER) of perihilar cholangiocarcinoma (PCCA) post-surgery. In a study of 434 patients, 15% experienced VER, significantly reducing median overall survival to 8.4 months compared to 38.5 months for those without recurrence (p
New nanosensor assay shows promise for early pancreatic cancer detection
A novel protease-activated nanosensor assay effectively identifies pancreatic ductal adenocarcinoma (pdac) in patients with high specificity and sensitivity. The assay achieved 98% specificity and 73% sensitivity for pdac samples and demonstrated an impressive 85% sensitivity for stage I pdac combined with the CA 19-9 biomarker. By leveraging serum protease activity, this rapid and noninvasive method […]
New Grading System Improves Patient Selection for Minimally Invasive Surgery
An international consensus has established a complexity and experience grading system to guide patient selection for minimally invasive pancreatoduodenectomy (mipd). This system categorizes patient-related risk factors and surgeon experience, enhancing decision-making in surgical procedures. The grading system is designed to mitigate the challenges in adopting mipd globally by emphasizing appropriate patient selection based on defined […]
AI-based scoring system enhances prognosis prediction for HCC
A novel AI-driven system effectively quantifies CD8+ tumor-infiltrating lymphocytes (TILs) in hepatocellular carcinoma (HCC) patients post-liver resection. In a study involving 514 patients, the automated CD8+ TIL scoring system (ATLS-8) revealed five-year overall survival rates of 34.05% for low-score and 65.03% for high-score cohorts. This research highlights the independent prognostic value of CD8+ TIL density, […]
Robot-assisted pancreatoduodenectomy costs become comparable to traditional methods.
A post-hoc analysis of 588 patients revealed that while robot-assisted pancreatoduodenectomy (rpd) incurs initial higher costs compared to open pancreatoduodenectomy (opd), outcomes improve significantly with experience. Total hospital stay shortened from 12 to 9 days, and costs per rpd procedure decreased from €32,836 to €21,778. By the second half of the study, total costs for […]
