The Role of Magnetic Resonance Imaging and Magnetic Resonance Cholangiopancreatography in Patients with Obstructive Jaundice

Abstract

Abstract:Objectives: The aim of this study is to evaluate the sensitivity, specificity and diagnostic accuracy of magnetic resonance cholangio-pancreatography in patients with obstructive jaundice after comparing it with the final diagnosis after surgical exploration and histopathological study. Methods: This study was held at Al-Yarmouk Teaching Hospital where patients with obstructive jaundice were investigated with magnetic resonance cholangio-pancreatography followed by surgical exploration and confirmation of diagnosis. Comparison of both results was carried out.Results: There were 42 patients, 26 females and 16 males. Their mean age was 59 years. 17 patients had common bile duct stones, 17 had malignancy, 3 had hydatid cyst, 2 had benign stricture and one patient had Mirrizi`s syndrome, chronic liver disease and biloma for each. After comparison with the final diagnosis after surgical exploration, the sensitivity, specificity and diagnostic accuracy of magnetic resonance cholangio-pancreatography were 100%, 92% and 95.2% respectively for those with common bile duct stones, while they were 94.1%, 100% and 97.6% respectively for those with malignancy.Conclusion: Magnetic resonance cholangio-pancreatography is of high diagnostic accuracy when used for patients with obstructive jaundice of different causes. In addition to its characters of being a non-invasive technique that need neither specific preparation nor anesthesia. We recommend using it on a wider scale in our country.Keywords: Obstructive jaundice, diagnosis, MRCP
