What features on intraoperative cholangiogram predict endoscopic retrograde cholangiopancreatography outcome in patients post cholecystectomy

摘要: Abstract Background Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure performed to remove bile duct stones. Intraoperative cholangiography (IOC) often at the time of cholecystectomy determine presence intraductal However, many ERCP procedures for this indication fail find any Given that carries significant patient morbidity, we investigated whether there are features on IOC can guide selection. Methods A retrospective analysis 152 patients who had an filing defect and subsequent was performed. Results Small single stones greater than or equal 4.5 mm be used predict ERCP. Furthermore, ERCPs filling defects smaller more likely negative if later rather earlier, suggesting small pass over time. We show 80% these will by 11 days after IOC. Conclusion Single should given adequate into intestine. Imaging stone has passed intestine day prior performing therapeutic
