[Cystic duct anatomy on DIC-helical CT].
Laparoscopic cholecystectomy (LC) is becoming increasingly common. When performing LC, the surgeon may face the risk of ductal injury because of the narrow visual field. Thus, detailed anatomical information on the biliary tree is necessary. DIC-helical CT was carried out in 39 patients suspected of having biliary diseases. The cystic duct was visualized in all cases. Posterior (30.8%) and posterolateral (17.9%) cysticohepatic junction were more common than in previous reports. The cystic duct took the anterior course of the bile duct in a few cases (12.8%). DIC-helical CT is useful for the noninvasive detection of biliary anatomy.
