The main indication for transcutaneous cholangioscopy through a channel of percutaneous trans hepatic drainage are choledocholithiasis, hepatolithiasis and non malignant or malignant steno sis of the bile ducts. In our department we were able to treat thus repeatedly also complete severing of the biliary pathways. Group: Twelve patients with complete severing of the right hepatic ducst (4x) or common bile duct (8x) after cholecystectomy could not be operated on account of great surgical risk or adhesions after operation. On account of cholangitis they had percutaneous transhepatic drainage. After three weeks transcutaneous cholangioscopy was per formed and recanalization by means of a needle shaped knife. The operation was terminated by introduction of a metal prosthesis Palmaz. Results: The method was successful in all patients, there were no complications associated with the procedure. Conclusion: Transcutaneous cholan gioscopy and recanalization of complete severing of the biliary pathways is a new safe method. It is indicated in patients with increased surgical risk. For restoration of the continuity of the bile ducts a metal prosthesis Palmaz is inserted. Short term results of treatment are satisfactors, long term results call for a longer follow up.
