Endoscopic sphincterotomy (EST) was performed in 53 patients with biliary disease. Indications for sphincterotomy were: 48 patients with choledocholithiasis, 3 patients with malignant biliary obstruction, and 2 patients with papillary stenosis. The procedure was successful in 52 patients (98.1%). In patients with choledocholithiasis, the stones were successfully removed or passed out spontaneously in 42 patients (87.5%). Endoscopic retrograde biliary drainage (ERBD) was successfully carried out in 2 cases of malignant biliary obstruction after EST. The clinical and biochemical evidence of cholestasis resolved in both patients with papillary stenosis. Complications consisted of hemorrhage (2 patients) and cholangitis (1 patient), resulting in one death. The overall complication and mortality rates were 5.7% and 1.9% respectively. Thirty-two patients received regular ultrasound examination follow-up with a mean of 13.4 months. Two patients had recurrent common bile duct stones and one had restenosis of papilla. The conditions were managed by endoscopic therapy. Endoscopic sphincterotomy is a relatively safe and effective means of relieving extrahepatic cholestasis; however, its comparison with surgical techniques needs long-term, randomized studies.
