本文發表了我們以經皮穿肝膽道鏡加上Dormina籃鑷和電擊碎石術的非手術性膽道道取石術的經驗,從1987年1月到12月,有39例膽道結石症病例共157次操作,所有的病例都有明顯膽道炎的徵象和症狀(發熱、惡寒和右上腹痛)。 經皮穿肝膽道攝影及引流(PTCD)是施行經皮穿肝膽道鏡前的必須步驟,以便造成皮膚和膽道問的通道,使膽道鏡能夠進入。 39例中有37例成功取出結石,成功率是95%,有2例因膽管狹窄或出血而失敗,並經膽道鏡和超道波追綜顯示結石已完全取淨,術後祇有較輕微的併發症,無嚴重併發症或死亡個例。
Our experience in non-operative removal of biliary tract stone through PTCS (percutaneous transhepatic cholangioscopy) plus the use of Dormia basket forceps and EHL (Electrohydraulic Lithotripsy) in some patients were presented. From Jan 1987 to Dec 1987, we reviewed 157 sessions of these procedures in 39 patients referred with the evidence of biliary tract calculi. All of them came in with suggestive sign and symptoms of cholangitis (fever, chills and right upper abdominal pain). PTCD (Percutaneous Transhepatic Cholangiography and Drainage) was a prerequisite procedureprior to PTCS in order to create a cutaxieou-biliary tract for choledoscopic entry. EHL was also used to remove a large biliary calculi which could not be retrieved by basket forceps alone. We successfully retrieved stones in 37 of 39 patients with a success rate of 95%. Complete removal of the stone should be evidenced by cholangiography and ultrasound followup. Only minor complications were encountered with no mortality even in a high risk patient.
