Abstract
Introduction: Biliary obstruction can occur anywhere in the tract carrying bile from liver to gall bladder and duodenum. Terminal CBD is the distal most part which is a common site for biliary obstruction. This study aims at finding various causes of terminal CBD obstruction and its characteristics using computed tomography imaging
Materials And Methods: Cross sectional study done at department of radiodiagnosis for a period of 2 years among 25 patients with clinically suspected obstructive jaundice and underwent contrast enhanced CT, diagnosed to have obstruction at terminal CBD level. CT diagnosis was correlated with ERCP or histopathology as applicable.
Results: Most common cause for terminal CBD obstruction was found to be periampullary malignancy (60%). Among them majority of cases were adenocarcinoma duodenum (53%). CT was (87%) accurate in detecting adenocarcinoma duodenum as the major cause of periampullary mass lesion.
Conclusion: Periampullary carcinoma is the common cause for terminal CBD obstruction
Keywords: periampullary mass lesion, adenocarcinoma duodenum, computed tomography.
