Abstract
ERCP with endoscopic sphincterotomy (ES) and stone extraction remains the treatment of choice for bile duct stones 1,2 ; 85% to 90% of all CBD stones can be effectively treated by ES and stone extraction by using balloon catheters or baskets. 3 Regarding the latter devices, impaction of a Dormia basket or fracture of the basket’s traction wires during endoscopic mechanical lithotripsy with an entrapped stone in the distal CBD is an uncommon but well-known complication, 4-6 presenting a challenge to most endoscopists. Reported management strategies include the use of a mechanical lithotriptor to capture the impacted basket and crush the stone, extracorporeal shock-wave lithotripsy, endoscopic laser lithotripsy, or other sophisticated methods. 7-12 This case series describes, for the first time, the safe and effective use of large-diameter balloon dilation of the biliary orifice in the management of impacted baskets in the distal CBD.
