The endoscopic papillotomy was performed to remove common bile duct stones. After the endoscopic papillotomy, the long catheter was inserted from the incized papilla into the common bile duct, and then, only the duodenof iberscope was pulled out to outside the body. By this procedure, this catheter has been able to retained in the common bile duct. The indwelling catheter method after endoscopic papillotomy was studied on this paper. This procedure could be successfully performed in 3 of the 4 patients. The retaining catheter method appears to be of value in the diagnosis and treatment of the biliary tract, and has many advantages as follows. 1) The ensuing cholangiography to observe whether the stone was delivered or not can be taken by this indwelling catheter. So there is no necessity to use duodenof iberscope. This method lightens a patients burder and prevent the damage of f iberscope from X ray. 2) Through this catheter, liquid lotion can be injected into the biliary tract to syringe it. This injection is useful to wash out the small stone from the biliary tract to the duodenum. 3) The antibiotics can be also given the bile duct through this catheter in the case of the biliary infection. 4) A solution for the stone can be poured into the bile duct through this catheter. 5) Insertion of the catheter into the bile duct is also useful method to prevent the complete stenosis of the incized papilla.
