Fluoroscopic view of large-balloon dilatation without biliary sphincterotomy. A. Cholangiogram demonstrating a large stone within the dilated bile duct. B. Large balloon inflated across over guidewire. The diameter of the balloon was selected according to the diameter of the stone and of the bile duct proximal to the tapered segment under fluoroscopic guidance. C.
