ThP6.2 - Benign and malignant biliary strictures encountered during single session laparoscopic cholecystectomy and bile duct exploration. Rationalising preoperative imaging and relying on routine cholangiography can optimise outcomes

Résumé fourni par la source

Abstract Aim To review causes, diagnostic features and operative strategies of biliary strictures discovered on routine cholangiography (IOC) during single session treatment of bile duct stones. Methods A prospective database of cholecystectomies and bile duct explorations spanning 30 years was analysed. Cross sectional imaging and ERCP play a limited role in patients with confirmed gall stones except in suspected malignancies.
