[Role of endoscopy in diseases of the extrahepatic bile ducts in patients after cholecystectomy].

The use of gastroduodenoscopy and retrograde pancreatocholangiography in patients after operation on bile ducts made it possible to choose the most effective therapeutic tactics. An analysis of the results of examination of 318 patients showed that most diseases of extrahepatic bile ducts after cholecystectomy were not correctable by surgery as a result of insufficient examination of the patients in the preoperative and operative periods. Endoscopic papillotomy is a method of treatment for patients with choledocholithiasis, stenosis of the major duodenal papilla (MDP) and MDP adenoma after operations on the beliferous system and can be regarded as an alternative to surgical operation. Surgical treatment in this group of patients is indicated for patients with extended stenosis of MDP and the terminal part of the common bile duct, strictures of the extrahepatic bile ducts and large-size choleliths in ineffective EPT.
