腹腔镜超声检查在腹腔镜胆囊切除术中的应用

目的 探讨腹腔镜术中超声（ＬＵＳ）在腹腔镜胆囊切除术（ＬＣ）中的作用以及ＬＵＳ对肝外胆道系统的扫描方法。方法 采用彩色多普勒腹腔镜超声仪对８０例胆囊结石患者行ＬＣ术中实时肝外胆道系统扫描。结果 ＬＵＳ能清晰地显示肝外主胆管的超声图象，对十二指肠下段胆总管的显示采用我们改进后的方法，能简便而满意地获得该部的胆总管超声图象；如何获取胆囊管的完整图象，仍须进一步探讨。结论 ＬＵＳ能在ＬＣ手术中为术者提供

Use of laparoscopic ultrasonographic scanning in laparoscopic cholecystectomy

Objective The value of laparoscopic ultrasonographic scanning (LUS) in laparoscopiccholecystectomy (LC) and the way of scanning extrahepatic biliary system were reported. Methods 80patients 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 theimage of the part posterior to duodenum could also be seen satisfactory with the method modified by the au-thors. But viewing the image of exact cystic duct needs further study. Conclusion LUS gives distinct in-traoperative sonographic images of extrahepatic bile ducts, thereby the operator can precisely locate the ductswithout injt_rying them. LUS can be considered as an important and safe supplement to LC.
