Abstract
Magnetic resonance cholangiopancreaticography (MRCP) and per-cutaneous trans-hepatic cholangiography (PTC) have a great role in the diagnosis of malignant obstructive jaundice, the level of obstruction and the degree of the obstruction.
The aim of this study was to evaluate the role of MRCP and PTC in the evaluation of malignant biliary obstruction.
This study was conducted on 30 patients, 18 males (60%) and 12 females (40%). Their age ranged between 36 to 85 years, with mean age of 59.9 years.
All examined cases in our study were subjected to the following: Full history taking, clinical examination, laboratory investigations and radiological investigations included: MRCP, PTC and US examination for all (30) cases, MDCT was done for 20 cases and biopsy was done for 25 cases.
In our study, elevated bilirubin level both total and direct bilirubin were seen at all the cases. The 30 patients examined by MRCP and PTC were categorized into 6 types according to the malignant cause of biliary obstruction. Cholanigocarcinoma included 46.7% of the cases, cancer pancreas included 26.7% of the cases, periampullary carcinoma and HCC included 10% of cases for each and GB carcinoma and gastric carcinoma included 3.3% of cases for each.
According to the level of obstruction, hilar biliary obstruction (63.3 %) was more common than distal type and the most common Bismuth type was Bismuth IV (33.3%).
