Objective: The aim of this study is to determine the diagnostic value of MR cholangiopancreatography in the diagnosis of biliary complications after cholecystectomy.
Smkjccts and methods: Twenty one patients with clinical findings suggestive of post-operative bile OBCt ipfury or biliary obstruction underwent MRCP, Fourteen patients were female and seven were male and their ages ranged from 18 to 66 years. Sixteen patients had undergone laparoscopic cholecystectomy sad five patients had open cholecystectomy. All patients were examined with a 1.5-T MR imaging unit (Sgm Excite; GE Medical Systems) using 8 channel phased array body coil. Each patient underwent mgnc axial T2 fat suppression and coronal T2 single shot fast spin echo of the abdomen before MRCP. AD patients underwent MRCP imaging with 2D Single Shot Fast Spin Echo (SSFSE) MRCP sequence, followed by a free-breathing 3D respiratory triggered Fast Recover.' Fast Spin Echo (FRFSE) MRCP aeqMcnce using Array Spatial Sensitivity Encoding Technique (ASSET) compatible coil. Endoscopic ictoograde cholangiopancreatography (FRCP) was done in sixteen patients and operative cholangiogram ■i three patients.
Jtemfts.- The diagnosis on MR cholangiopancreatography were as follows: excision ligation of the mnbDe ducts (n = 3). strictures of the main bile ducts (n = 4), bile leak (n-3), common bile duct blood dot(a = 1). retained (slipped missed) CBD stones in (n=4) and long cystic duct stump with retained stones (a=2) and normal MRCP study (n=5). The final diagnosis was made on bases of findings at surgery in three ■frnrr ERCP in thirteen patients and clinical, laboratory & MRCP follow up in five patients.
Conclusion: MR cholangiopancreatography is an accurate diagnoslic tool in diagnosis of post¬cholecystectomy biliary complications including bile duct injuries & their classifications which are essential for plan of management and can also accurately diagnose retained stones in CBD & cystic duct remnant. Wbile in bile duct leak MRCP can only suggest bile leaking which can be accurately diagnosed in the near future by use of functional or dynamic MRCP.
