Identifying patients most likely to have a common bile duct stone after a positive intraoperative cholangiogram.

摘要: The false-positive rates of a positive intraoperative cholangiogram (IOC) are as high 60%. Endoscopic retrograde cholangiopancreatography (ERCP) for stone removal is required after IOC. It unclear which clinical factors identify patients most likely to have This study was conducted predictive common bile duct (CBD) stone(s) on ERCP A retrospective review our endoscopic database identified all and/or ultrasound (EUS) procedures performed IOC between August 2003 and 2009. Collected data included patient demographics; indication cholecystectomy; findings; blood tests before cholecystectomy, including liver function tests, complete count, amylase lipase measurements; EUS results. Patients who had negative CBD stones no subsequent were contacted by phone see if they eventually an ERCP. Univariate multi-variable analyses performed. total 114 in the study. findings single stone, multiple stones, nonpassage contrast into duodenum, dilated CBD, poor visualization duct.
