AbstractThis study reports our first year's experience of endoscopic sphincterotomy for common bile duct stones. Forty patients were considered for the procedure and it was attempted in 37. An effective endoscopic sphincterotomy was eventually achieved in 32 (86 per cent), 7 after a ‘pre‐cut’. Twenty‐three patients passed stones spontaneously (72 per cent), 6 could not be reassessed and 3 still had stones present (9 per cent). Bed occupancy was 9·5±5·9 days.Complications occurred in 30 per cent, the most common being pancreatitis in 6 cases with 1 death.It is concluded that endoscopic sphincterotomy offers a valuable alternative to surgery in the management of common bile d
