Abstract

In this study we evaluated by blinded design the diagnostic efficacy of two noninvasive techniques, quantitative hepatobiliary scintigraphy (QHS) and fatty-meal sonography (FMS), for evaluating patients with suspected partial common duct obstruction. Quantitative hepatobiliary scintigraphy was performed on 56 cholecystectomized individuals (22 asymptomatic controls, 28 patients with suspected partial common duct obstruction, and 6 nonjaundiced cirrhotics) and FMS was done in 51 cases. For QHS, time-activity curves were generated for regions of interest over the liver, hepatic hilum, and common duct. For FMS, we measured common duct diameter before and 45 min after a fatty meal (Lipomul, 1.5 ml/kg). Each of the 28 patients with suspected partial common duct obstruction and 6 cirrhotic patients underwent endoscopic retrograde cholangiography, often accompanied by sphincter of Oddi manometry. Findings from these examinations were taken as the gold standard to determine the presence or absence of conditions that could account for intermittent symptomatic partial common duct obstruction. The most sensitive indicators for a positive test were a 45-min isotope clearance of less than 63% for QHS and a common duct increase of greater than or equal to 2 mm after the fatty meal for FMS. Of 28 patients with suspected partial common duct obstruction, 15 were judged to be true-positive and 13 true-negative. The 6 cirrhotic patients were without common duct obstruction. The study findings showed that each test had a 67% sensitivity that improved to 80% when the findings from both test results were combined. The specificity of QHS was 85% and that of FMS was 100%. All 6 cirrhotic patients had negative findings on FMS and 4 were false-positive on QHS. The true-positives included 8 patients with a small common duct stone and 6 with obstructive sphincter of Oddi dysfunction (4 stenosis, 2 dyskinesia). We conclude that noninvasive QHS and FMS afford good sensitivity and specificity for evaluating cholecystectomized patients with suspected partial common duct obstruction.
