Endoscopic balloon dilatation (EBD) of the biliary sphincter may be an alternative to endoscopic sphincterotomy (EST) for removal of bile duct stones. After EBD of the biliary sphincter to a diameter of 8 mm, stones are removed according to standard guidelines. In the event that stone removal fails after EBD, an additional EST is performed. The overall success rate of stone removal after EBD (90%) is comparable to that of EST. After EBD, an additional EST and mechanical lithotripsy are required in 10% and 30% of patients, respectively. In patients with bile duct stones<10 mm and a stone number<or = 3, EBD is nearly always successful without the need for additional EST or mechanical lithotripsy. Pancreatitis post-EBD occurs at a rate of 5-7%, which is not significantly different from that after EST. Significant bleeding post-EBD has not been observed in over 400 patients undergoing EBD. EBD is a valuable alternative to EST, especially in patients with smaller bile duct stones and in patients with haemostatic disorders.
