Endoscopic sphincterotomy in the treatment of choledocholithiasis and ampullar stenosis. Experience with 202 patients.
Endoscopic sphincterotomy (EST) was performed on 202 patients (265 EST) in the 5-year period 1978-1983 because of choledocholithiasis or benign stenosis of the ampulla of Vater. The indications for EST in choledocholithiasis included residual or recurrent stone(s) in 80 cholecystectomized patients, and 96 had choledocholithiasis with the gallbladder in situ. Ductal calculi passed spontaneously after EST in 87 cases (50%) and were actively extracted in 73 (41%). Ductal clearance failed in 16 patients. The overall success rate thus was 91%. Ampullar stenosis was successfully treated in 26 patients. Sphincter stenosis after EST was diagnosed in one patient. Immediate complications of EST arose in 31 patients (11.7%), one of whom died. Emergency laparotomy was required in three cases (1.1%). EST with or without stone extraction is a relatively safe procedure for managing choledocholithiasis in high-risk patients before cholecystectomy is considered, and also for stones retained or reformed after cholecystectomy. Endoscopic treatment may offer appreciable clinical and financial benefits by reducing morbidity and mortality rates and shortening hospitalization and convalescence time.
