BILE STASIS IN PATIENTS WITH PRIMARY BILE DUCT STONES
－ITS ANALYSIS ON HEPATOBILIARY SCINTIGRAM－

The technetium Tc 99M-labeled iminodiacetic acid cholescintigram was an extremely accurate examination for detecting any grade of cholestasis in the common bile duct in patients with primary bile duct stones (PBS), congenital cystic dilatation of the common bile duct (CDC) or anomalous arrangement of the pancreatobiliary ductal system (AAPB). The examination was performed on 78 patients, including 35 with PBS, 18 with CDC, 8 with AAPB and 17 of normal controls. We showed bile stasis by the index of the highest activity value on the scintigram in the bile duct vs. the value in the right hepatic parenchyma.
The index of the normal controls was 1.3±0.6 and bile flow hours in the papillary region of the duodenum were 4.1±3.5 minutes. While, in the patients with CDC the index was 2.7±2.4 and the hours were 3.0±2.4 min. And in the patients with PBS, the index was 3.5±2.3, and the hours were 3.5±2.5 min. and the index was significantly higher than that of the controls. However, we could not find correlation between the index and the bile flow hours in patients with PBS and those with CDC. Accordingly we thought that bile stasis in patients with PBS was not caused by the disturbances of bile flow in the papillary region but by the congenitally dilated condition of the bile ducts.
