Description
Summary:Laparoscopic sonography was introduced at our institution in April 1991. It is presently being tested as an alternative to peroperative cholangiography as far as the visualization of the structures of the hepatoduodenal ligament--particularly the extrahepatic bile ducts--during laparoscopic cholecystectomy are concerned. So far, 75 patients have been examined with both modalities. The structures of the hepatoduodenal ligament could be seen sonographically in all patients, while in five patients, the cholangiography had to be aborted for technical reasons. Eleven patients (15%) had anatomical variations of the bile ducts. Nine of these were diagnosed sonographically. A duodenal diverticulum and a long common channel of common bile duct and pancreatic duct were seen only on cholangiography. Variations of the hepatic arteries were found in 15 patients (20%). We conclude that intraoperative laparoscopic sonography is a reliable tool for the visualization of the structures of the hepatoduodenal ligament. This new technique might replace peroperative cholangiography in the future.
