Abstract

A 63-year-old man, with a body mass index of 32 kg/m2, was admitted with obstructive jaundice due to cholecysto-choledocholithiasis. He was febrile and had had subcostal pain for at least 3 weeks. Endoscopic retrograde cholangiopancreatography (ERCP) confirmed the presence of stones in the common bile duct (CBD). Papillotomy was carried out and stone retrieval commenced with a Dormia basket. One stone became entrapped in the Dormia basket and it was impossible to remove it through the papilla. A Soehendra mechanical lithotripsy device was advanced over the Dormia basket with the intention of fragmenting the stone. However, the stone did not fracture on application of force ([Fig. 1]). On increase of the level of force applied, the Dormia basket deformed ([Fig. 2]) and eventually fractured, with its tip and the embedded stone remaining in the distal CBD.
