VARIATIONS OF BILIARY DUCTALANATOMY ON MRCP

Abstract

Introduction:- Biliary anatomy and its common and uncommon variations are of considerable clinical signicance when performing living donor transplantation, radiological interventions in hepatobiliary system, laparoscopic cholecystectomy, and liver resection (hepatectomy, segmentectomy). Thus, magnetic resonance cholangiopancreatography (MRCP) has become the modality of choice for noninvasive evaluation of abnormalities of the biliary tract. The purpose of this study is to describe the variations of biliary ductal anatomy on MRCP. Material And Method:- Hospital based prospective study for a period of 1 year and 6 months in Department of Radiodiagnosis, AIMSR Bathinda after applying inclusion and exclusion criteria and after obtaining their informed written consent. Results:- In our study of the anatomical type of right hepatic duct, A1 type was most commonly found type in 75.2% (n=100) of patients out of which 65% (n= 65) of patients were found to be females and 35% (n=35) were found to be males. Left hepatic duct was found to be A1 type in 100 % of patients out of which 65.4 was females and 34.5 % was males. In our study, cystic duct insertion was found to be right lateral in 78.9% (n=105) of patients out of which 64.8% (n= 68) of patients were found to be females and 35.2% (n=37) were found to be males. Conclusion:-It was noticed that A1 remains the most common type of right hepatic duct but still one should be cautious for other types as they still make for one fourth of cases. Similarly, In case of cystic duct, although Right lateral type was most commonly encountered but since other types were found in nearly one fourth of patients, one should be on active look out for them too
