Abstract
Background:obstructive jaundice is a common clinical problem in medical practice.The condition can becaused by theobstruction of the bile duct with choledocholithiasis, strictures and hepato-biliarymalignancy.
Objective: To assess imaging spectrum, level and pattern of obstructive jaundice on cross sectional imaging, CTand MRCP
Methods: A retrospective analysis of all patients admitted with a diagnosis of obstructive jaundice atTikurAnbessa hospital fromJan 2010 to Aug. 2012 E.CThe data were collected from patient medical records and PACS using pretested, structured data extractionformat was used to collect the data, which were entered onto andanalyzed using SPSSversion 2 5.
Results: A total of 105 patients, 73 (69.5%)were males. Theirage ranged from 25 to 83 years with a mean ageof 53(±SD)13.8years. 79(75.2%) of the cases had malignant causes while the rest 26(24.8%) had benign causesfor obstructive jaundice. The most common malignant lesion was cholangiocarcinoma with 33 cases followedby pancreatic cancer which was seen in 28 cases. The most common benign lesion seen wascholedocholithiasis which was seen in 9 cases followed by benign Stricture which had 6 cases . The commonestsite of obstruction was at the peri- ampullary region in 40(38.1%) of the cases followed by distal common bileduct and the hepatic hilum with 35(33.3%) and 20(19%) respectively. The most common imaging findings was an enhancing intraluminal soft tissue mass which was present in 67(63.8%) which was followed by a focal wallthickening.Abdominal CT and MRCP wasthe main imaging modality used.
Conclusion:The most common imaging spectrumof obstructive jaundice are malignant lesions with cholangiocarcinoma being the commonest and choledocholithiasis is the commonest benign causenoted withperiampullary region the commonest level/site of obstructi ve jaundice and intraluminal enhancing mass thecommonest pattern noted both in the cholangiocarcinoma and pancreatic head tumor.
