Highlights Alkaline phosphatase: sensitivity of 97.6% and specificity of 72.6% for choledocholitiasis. The average cost of cholangioresonance would have decreased by almost half for each patient in this study. ABSTRACT Objective To assess the predictive value of preoperative serum laboratory test results for identifying choledocholithiasis and reduce the use of cholangioresonance and its inherent costs. Methods Patients aged 21-69 years who underwent preoperative cholangioresonance examination at our institute were included.

ABSTRACT Objective: To determine the period during which we should avoid cholecystectomy after endoscopic retrograde cholangiopancreatography. Methods: A retrospective analysis of electronic medical charts of 532 patients undergoing endoscopic retrograde cholangiopancreatography, between March 2013 and December 2017. Results: Approximately one-third of patients underwent the procedure between 4 and 30 days after endoscopic retrograde cholangiopancreatography. The conversion rate was 3.8%. The need for abdominal drainage and the finding of biliary tract injury after surgery were observed in 15.1% and 1.9% of […]
