[Recurrent and residual stones in the bile ducts].
Data of 205 patients with recurrent (48) and residual (157) choledocholithiases are presented. In most observations postoperative cholelithiasis proceeded by the type of chronic intermittent obturation of bile ducts. Highly effective method of diagnosing recurrent and residual calculi is thought to be the endoscopic retrograde pancreatocholangiography, best results of the treatment being obtained after the endoscopic papillosphincterotomy which should be used as the operation of choice.
