EXPERIENCE OF EVALUATION OF PATIENTS OF OBSTRUCTIVE JAUNDICE BY SONOGRAPHY AND MAGNETIC RESONANCE CHOLANGIOPANCREATOGRAPHY AT A TERTIARY CARE CENTRE IN EASTERN INDIA

INTRODUCTION: Jaundice means yellow due to the yellowish discolouration of skin, sclera, and mucous membrane seen in jaundice caused by bilirubin pigment. It is divided in to two forms obstructive(surgical) and non- obstructive (non-surgical). AIM AND OBJECTIVE: To evaluate patients of obstructive jaundice by sonography and magnetic resonance cholangiopancreatography and compare the reporting and ndings by both the modalities. MATERIALS AND METHODS: Cross sectional observational study done from November 2018 to October 2020 and consists of 32 patients who had clinical jaundice and consented to being subjected to both ultrasound and MRCP. OBSERVATIONS:Both USG and MRCP were able to detect extrahepatic CBD dilatation equally in 25 patients. In 5(15.6%) patients USG and MRI both demonstrated intrahepatic mass causing obstruction at the level of conuence of right and left hepatic duct or CHD. Ultrasonography was able to detect the intrinsic mass of the extrahepatic common bile duct in 2(6.2%) patients out of 32 patients in our study population. MRCP could detect the same in 6(18.7%) patients. In our study narrowing of CBD with stricture formation and upstream dilatation of biliary tree was identied in 10(31.2%) patients on MRCP. Ultrasound could diagnose the same in one patient. Both USG and MRCP were able to detect pancreatic head mass as well as pseudocyst. CONCLUSION: The accuracy of MRCP was found to be comparable to that of ERCP for diagnosis of etiology for obstructive jaundice. MRCP allows better lesion characterization and assessment. However, the patchy availability of MR machines become the main achilles heel for the surgeons as well as the radiologists. Hence the valuable role of the omnipresent ultrasonography become immense.
