Value and accuracy of multidetector Computed Tomography in obstructive jaundice

Mathew Rishi, Moorkath Abdunnisar, Hadihally Suresh


The present study was carried out to find out the role of MDCT in the evaluation of obstructive jaundice with respect to cause and level of the obstruction and to correlate CT findings with histopathology/surgical findings/Endoscopic Retrograde Cholangio Pancreatography (ERCP) findings as applicable. This was a prospective study conducted over period of one year from August 2013 to August 2014. Data were collected from 50 patients with clinically suspected obstructive jaundice. CT findings were correlated with histopathology / surgical findings/ ERCP findings as applicable. Among the 50 people studied, males and females were equal, and majority belonged to 41-60 year age group. The major cause for obstructive jaundice was choledocholithiasis. MDCT with reformatting techniques was very accurate in picking a mass as the cause for biliary obstruction and was able to differentiate a benign from malignant one with high accuracy. There was 100% correlation between the CT diagnosis and the final diagnosis regarding the level and type of obstruction. MDCT was able to determine the cause of obstruction with an accuracy of 96%. MDCT with good reformatting techniques has excellent accuracy in the evaluation obstructive jaundice with regards to level and cause of obstruction
