Abstract

A retrospective study comparing ultrasound (US) and endoscopic retrograde cholangiopancreatography (ERCP) as practiced on 42 jaundiced patients. Obstruction of the bile ducts was demonstrated in 21 by US and in 33 by ERCP, this latter method was taken as the gold standard for comparison, and thus the sensibility of US for detecting obstructive jaundice was 64% and specificity was 89%. Choledocolithiasis and papillary stenosis were the most frequent etiologies, diagnosed in 26 cases by ERCP and in 14 cases by US. Of the 36 patients with gallbladder, US demonstrated gallstones in 28 cases (78%) and ERCP in 18 (50%). We conclude from this study that US has a high sensibility and specificity in patients in whom obstructive jaundice is suspected.
