Use of laparoscopic ultrasonographic scanning in laparoscopic cholecystectomy / 中华消化内镜杂志

ABSTRACT

Objective The value of laparoscopic ultrasonographic scanning (LUS) in laparoscopic cholecystectomy (LC) and the way of scanning extrahepatic biliary system were reported. Methods 80 patients with gallstone receiving LC had real－ time color Doppler LUS of the extrahepatic biliary system. Results The sonic picture of major extrahepatic bile duct could be clearly visualized by LUS. While the image of the part posterior to duodenum could also be seen satisfactory with the method modified by the authors. But viewing the image of exact cystic duct needs further study.Conclusion LUS gives distinct intraoperative sonographic images of extrahepatic bile ducts , thereby the operator can precisely locate the ducts without injurying them. LUS can be considered as an important and safe supplement to LC.
