Background: Post-cholecystectomy choledocholithiasis re-currence is a common complication among patients due to lack of pre-operative assessment of biliary tract stones. Also con-comitant pathologies (eg. Gall bladder abscess, etc) necessitate proper pre-operative assessment which in many settings can't be achieved by the standard pre-operative ultrasound. Aim of Study: The purpose of this study was to assess the ability of pre-operative MRCP to decrease many of the post-op-erative complications. Patients and Methods: Between May 2023 & February 2024, 148 patients presented with acute cholecystitis (based on clinical and ultrasound data) had pre-operative MRCP exami-nation. All the patients had normal liver function tests, bilirubin levels and had no evidence of biliary dilatation by US. Results: Out of 148 patients (76 males & 72 females), 34 patients had common bile duct stone, 14 had extra-hepatic bil-iary (common hepatic and common bile ducts) stones while 16 had intra-hepatic biliary tract stones. None of the common hepatic, CBD or intra-hepatic biliary stones were detected by ultrasound. Conclusions: Magnetic resonance cholangiopancreatogra-phy (MRCP) was found of great value in pre-operative detec-tion of choledocholithiasis, possible complications and in de-creasing post-operative symptoms of choledocholithiasis.
