The development of bile duct stones is a common biliary tract disorder in Taiwan. Surgery and choledochoscopy are the current methods of treatment. The purpose of this study was to describe percutaneous transhepatic intervention under fluoroscopy for the removal of biliary stones. Between July 1998 and June 1999, 46 patients with obstructive jaundice, biliary colic, and cholangitis secondary to the biliary stones underwent percutaneous biliary stone removal under fluoroscopy. Angiographic superselective catheterization technique was employed for superselective cholangiography to identify the location of stones and to deliver the basket and electrohydraulic lithotripsy (EHL) probe to the site of the stones. Most of the patients needed multiple sessions (four on average) to remove all the stones. Chills and fever were the procedure-related complications. Four patients (8.7%) had recurrent stone formation during 2 to 12 months of follow-up. Percutaneous biliary stone removal under fluoroscopy is of benefit for direct visualization of the location and number of stones and the architectural changes of the bile ducts.
本研究計劃中有46位患者接受X-光透視下經皮穿肝膽道取石之手術。這些患者常合併有阻塞性黃膽，膽絞痛及膽管炎。血管攝影的超選擇性導管操作技術可應用來作超選擇性膽道攝影，也可利用於將取石套籃或電擊碎石的探頭送到膽石的位置。
為了取出所有的膽道結石，大部分的病患需要施行多次的取石術(平均4次)。發燒，畏寒，胰臟炎，肝動脈損傷及膽管穿孔是施行此手術時可能引發的併發症。
X-光透視下經皮穿肝膽道取石術的優點在於可以直接清楚的觀察到結石的數目及位置，同時也可以明瞭膽道結構的變化。
