Abstract
The purpose of this study was to compare laparoscopic intracorporeal ultrasound (LICU) examination of the biliary duct system with cholangiography for delineation of duct anatomy and determination of presence or absence of ductal calculi. Thirty-one patients had LICU examination of the extrahepatic bile ducts after exposure of the gallbladder but prior to dissection of the cystic duct. After LICU examination, cystic duct dissection and cholangiography were done. Evaluation of duct anatomy and decision for duct exploration were based on findings of both tests. All patients had successful LICU examination and 30 had successful cholangiography. Duct size as determined by LICU corresponded precisely with cholangiography. LICU provided useful anatomical information in two patients with aberrant anatomy and detected choledocholithiasis in five, one of whom had a negative cholangiogram. LICU aids in delineation of biliary duct anatomy and accurately determines presence or absence of duct calculi.
