Comparative assessment of MRCP with ERCP in Obstructive Jaundice

Abstract

Introduction: Evaluation of suspected biliary obstruction typically involves various imaging techniques such as ultrasonography (USG), computed tomography (CT), and invasive cholangiography. In cases where ultrasound and CT fail to visualize intraductal stones adequately, invasive procedures like Endoscopic Retrograde Cholangio-Pancreatography (ERCP) and noninvasive radiation free MRCP become necessary. Materials and Method: All patients presenting with signs or symptoms of biliary or pancreatic pathology after initial clinical evaluation by a senior surgeon or physician, or those referred for evaluation of biliary or pancreatic pathologies. Result: Study population for obstructive jaundice was between 46-55 years. For gall stone detection, MRCP had specificity and sensitivity of 80% and 100% respectively where as ERCP had 100% each. For bile duct stones MRCP had sensitivity and specificity of 88.24% and 100% respectively and sensitivity and specificity of ERCP was 100% each. In detecting strictures it was observed that MRCP had sensitivity and specificity of 94.74 % and 100% respectively. Sensitivity and specificity of ERCP was 100% each. In detecting choledochal cyst, it was observed that MRCP had both sensitivity and specificity of 100 %. Sensitivity and specificity of ERCP was 100% each.
