title: Surgical intervention following fragmentation of gallstones by extracorporeal shock waves.
abstract: Five cases of surgical intervention following extracorporeal shock wave lithotripsy (ESWL) of gallbladder and bile duct stones are reported. This represents an incidence of surgical intervention in 1% of patients with gallbladder stones and in 9% of patients with common bile duct stones who underwent ESWL during a two-and-a-half-year investigation period. There was no mortality. In 2 patients with gallbladder stones and persistent colic after ESWL, elective cholecystectomy was performed. There was no evidence of macroscopic or microscopic damage or bleeding within the wall of the gallbladder. Furthermore, no damage to the liver, common bile duct, duodenum, or stomach was noted. ESWL was applied in 34 patients with common bile duct stones in whom endoscopic sphincterotomy and stone extraction had proved ineffective. Three (9%) of these patients required surgery. In 1 patient, a Dormia basket got stuck and the basket, together with the stone, were removed by choledochotomy. In a second patient, rupture of a juxtapapillary diverticulum occurred 10 days after ESWL and 2 days after endoscopic extraction of stone fragments. At laparotomy, the retroperitoneum was drained. In a third patient with gallbladder and common bile duct stones, acute cholecystitis developed after lithotripsy of common bile duct stones. Cholecystectomy was performed and a t-tube was inserted in the bile duct. In all patients, the postoperative course was uneventful. In our experience, ESWL is a safe procedure with no mortality and an infrequent need for surgical intervention.
