About

This study was done to evaluate the diagnostic statistics of MDCT and its features in the assessment of obstructive jaundice in reference to surgical or histopathological diagnosis.

Full description

We did a cross-sectional study among 30 participants of obstructive jaundice at BP Koirala Institute of Health Sciences (BPKIHS), Dharan, Nepal. The sensitivity and the Negative predictive value of MDCT for non-neoplastic cause to detect obstructive jaundice were 100% (95% CI 79.41-100.00) and 100% (95% CI 75.29-100.00), while the specificity and the Positive predictive value for neoplastic cause to detect obstructive jaundice were 100% (95% CI: 79.41-100.00) and 100% (95% CI: 75.29-100.00). Similarly, the accuracy for either non-neoplastic or neoplastic cause was 96.67% (95% CI: 82.78-99.92). The most common cause for obstructive jaundice was choledocholithiasis (33.34%) followed by cholangiocarcinoma (20%), ampullary carcinoma (13.33%) and choledochal cyst (13.33%). The diagnostic accuracy of individual etiology of common causes of obstructive jaundice ranged from 82.78 to 100%. Biliary obstruction was most frequently observed in the periampullary region (83.33%), followed by the proximal common bile duct (6.67%), hilar region (6.67%), and intrahepatic region (3.33%).The MDCT could serve as the initial, cost-effective, easily available, and time-efficient imaging modality for diagnosing various causes of obstructive jaundice. It can differentiate non-neoplastic from neoplastic causes of obstructive jaundice.
