In this article, we demonstrated that the curative effect of laparoscopic operation was satisfied from 46cases of laparoscopic cholecystectomy, and sum up ourbeginning experience and lesson, such as treatment forbleeding of cystic artery; prevention of injury of commonbile duct and the escape of bile; treatment for rupture of the gallbladder and the escape of stones to the abdominal cavity. We also stressed that high vigilanceshould be maintained to prevent "accidentally injury" ofviscera by the instruments and occurrence of incisional hernia and other complications.

本文选用成年家犬通过手术建立胰胆返流致石膜型.在人为胰胆返流七 d 后。伴有胆管完全梗阻的 A 组和部分梗阻的 B 组胆汁的胆汁酸、卵磷脂、胆红素显著减少。胆固醇浓度相对升高,胆汁沉淀压积增多,且肝外胆系有胆砂形成。单纯胰胆返流而无胆总管下段梗阻的 C 组,四种成分都减少及未见肉眼胆砂,但有胆红素钙及胆固醇结晶沉淀。D 组(对照组)夹管造成胆管暂时性梗阻但无胰胆返流。则胆汁各成份基本按比例升高,肝外胆系既无胆砂,又无胆红素钙及胆固醇结晶.根据实验结果,推论胰胆返流是胆石症重要病因之一。本文还讨论了胰酶致石的作用机制。建议采用手术方法中断胰胆返流,有助于防止胆石形成和复发。
