We have been using cholangioscopic laser lithotripsy since 1980. From 1980 to 1990 we have treated with cholangioscopy 9 patients with cholecystolithiasis (1 recurrent case), 28 patients with choledocholithiasis and 68 patients with hepatolithiasis. Patients for whom we used percutaneous transhepatic cholangioscopic therapy for cholecystolithiasis and choledocholithiasis were those of polysurgery, aged patients and patients who had some complications. We established a treatment plan for hepatolithiasis; first, percutaneous transhepatic cholangioscopic lithotripsy was performed whenever possible. But if there was an atrophic lobe or stenotic bile duct making it impossible to removed the stones, liver resection or other operative procedures were performed. With this treatment we had only 2 cases (2.9%) in which were residual stones. From 1988 we used a flash lamp pumped dye laser for lithotripsy, this apparatus led to progress in the cholangioscopic treatment and shortened the treatment period.
