A study analyzing the branching patterns of the right intrahepatic portal vein identified 12 distinct types, emphasizing the anatomical variations of the right anterior and posterior portal veins. Three-dimensional visualization technology was utilized to analyze 711 patients, revealing the cranio-caudal and ventro-dorsal configurations among others. These findings provide clinicians with critical insights into portal vein […]

Adjuvant PD-1 inhibitors enhance survival in high-risk HCC patients.
In a study involving 199 hepatocellular carcinoma patients, the use of adjuvant PD-1 inhibitors significantly improved both recurrence-free survival (RFS) and overall survival (OS) rates. After propensity score matching, 1-year RFS was 87.1% for those receiving PD-1 inhibitors versus 44.6% for non-recipients, while 1-year OS rates were 98.5% versus 90.7%, respectively. The findings suggest that […]
Metabolic syndrome increases cholangiocarcinoma risk significantly.
A large-scale population-based cohort study involving 4,932,211 adults revealed that individuals with metabolic syndrome face a significantly heightened risk of cholangiocarcinoma, with a multivariate-adjusted hazard ratio of 1.20. During 35,879,371 person-years of follow-up, there were 6,117 identified cases, with incidence rates rising in correlation with the number of metabolic components. Those with five metabolic factors […]
Broad-spectrum penicillin antibiotics improve pancreatoduodenectomy outcomes
A systematic review involving 12,469 patients indicates that broad-spectrum penicillin-based antibiotics (bs-ab) notably reduce surgical site infections, postoperative pancreatic fistula rates, and mortality compared to standard cephalosporins. Specifically, bs-ab led to a 47% decrease in surgical site infections and a 38% reduction in postoperative pancreatic fistulas. Notably, benefits were enhanced for patients with preoperative biliary […]
Combined imaging improves accuracy for detecting liver metastases
Combining contrast-enhanced CT with MRI significantly boosts the detection of colorectal liver metastases, achieving sensitivity rates of 96.5% compared to 90.6% for MRI alone. Specificity also improved, from 95.3% to 98.3%. Notably, radiologists reported higher diagnostic confidence in 78.8% of cases with the combined approach, up from 64.7% with MRI alone. Additionally, inter-observer agreement reached […]
Prognostic model predicts recurrence and treatment response in HCC
A novel prognostic model utilizing pathological signatures effectively predicts postoperative recurrence risk and sorafenib response in hepatocellular carcinoma (HCC) patients. Analyzed across 287 non-treated patients, the model achieved AUROC values of 0.818 and 0.811 for predicting one and two-year recurrence respectively. Validation with an external cohort confirmed its predictive power. Additionally, it successfully stratified sorafenib-treated […]
Transarterial embolization effectively manages liver cancer hemorrhages
Transarterial embolization (TAE) demonstrates a 100% hemostasis success rate in treating ruptured hemorrhages and postablation bleeding in liver cancer patients. The 30-day survival rates were 90.91% for the rupture group and 100% for the ablation group, with 1-year survival rates of 45.45% and 85.19%, respectively. Although liver function changes occurred postoperatively, they remained comparable to […]
Opioid prescriptions significantly decreased after hepatectomy
A comprehensive analysis revealed that opioid reduction strategies initially aimed at pancreatectomy markedly influenced posthepatectomy prescribing. With a cohort of 2,005 patients, researchers documented over a 50% reduction in intraoperative and total inpatient opioid use, coupled with a 73% decline in discharge opioids. Importantly, patient pain scores remained stable, and the percentage of opioid-free discharges […]
EUS-PD shows high success rates and manageable adverse events
A systematic review and meta-analysis of endoscopic ultrasound-guided pancreatic duct drainage (EUS-PD) revealed significant effectiveness, with technical success at 89% and clinical success at 88%. Examining 27 trials involving 902 patients, the study also noted a 17% rate of adverse events, primarily post-EUS-PD acute pancreatitis at 3%. Other complications like bleeding, perforation, pancreatic leak, and […]
Iwate scoring system effectively stratifies laparoscopic liver resections
An international multicenter study validated the Iwate difficulty scoring system (DSS) for laparoscopic liver resections (LLR) across both its four difficulty levels and 12-point difficulty index. Analyzing 14,759 patients, researchers found that intraoperative and postoperative outcomes—such as operation time, blood loss, and complications—worsened significantly with higher difficulty levels (p < 0.001). These findings, derived from […]
