AbstractIntroduction: Obstructive jaundice is one of the most frequent symptoms of hepatobiliary disease and caused by various diseases. So, it is mandatory to determine pre-operatively the existence, the nature and level of obstruction because an ill chosen therapeutic approach can be dangerous. MRCP demonstrates details anatomy and pathology of the biliary and pancreatic ducts. Ultrasonography still remains the first imaging modality for obstructive jaundice. Hence, aim of the present study was to evaluate the diagnostic efficacy of ultrasonography (USG) against magnetic resonance cholangiopancreatography (MRCP) in obstructive biliopathy in detection and characterization in patients suspected with pancreatic and biliary system pathologies.
Material and methods: This study was conducted among sixty patients suffering from obstructive jaundice of all age groups. All the patients in the study underwent ultrasonography and MRCP. The result so obtained was expressed as percentages and variables as required.
Results: In our study, the most common cause of obstructive jaundice was common bile duct stones (55%) followed by tumors (22%) then benign strictures (7%), choledochal cyst (7%), chronic pancreatitis with pseudocysts (7%) and Mirizzi syndrome (3.33%). Diagnostic accuracy of ultrasound in obstructive jaundice taking MRCP findings as gold standard revealed sensitivity, specificity and diagnostic accuracy in benign cases as 97%, 67% and 97.4% and in malignant cases as 86%, 100% and 87.5% respectively.
Conclusion: USG has a high potential efficacy in diagnosing causes of obstructive jaundice. So, it is considered as an initial screening modality to confirm or exclude biliary dilatation & to choose patients for MRCP examination
