Abstract
Retained or recurrent stones in the common bile duct remain a clinical problem in 2% to 5% of patients undergoing cholecystectomy. Nonoperative extraction via the T tube tract or endoscopic sphincterectomy is successful in 85% to 95% of patients; however, the remainder require reoperation. This study evaluates the efficacy of electrohydraulic shock wave lithotripsy therapy of common duct stones too large to be extracted endoscopically or by T tube. Six patients were entered into the study. Ages ranged from 62 to 93 years. All patients either had severe preexisting systemic disorders or were of an advanced age. Stones ranged in size from 10 to 41 mm, with a mean largest dimension of 22 mm. In all patients either extraction by traditional nonoperative means failed or there was a stone that was considered to be too large to be extracted successfully. Patients were treated with 1200 to 2400 shocks at 16 to 20 kV. Five of six patients were treated with local anesthesia and sedation. Stones were successfully fragmented in all but one patient. Five patients required extraction of the remaining fragments either through the T tube tract (one patient) or via endoscopic sphincterectomy. All patients were free of stones at discharge, with the exception of one patients with severe cirrhosis who had an intrahepatic stone behind a right hepatic duct stricture. This stone had been successfully fragmented but an endoscopic retrograde cholangio-pancreatogram revealed some residual fragments despite normal alkaline phosphatase and bilirubin values. There were no hospital deaths, although the patient with the intrahepatic stone died of bleeding varices several months later. Electrohydraulic shock wave lithotripsy seems to be an effective adjuvant treatment in clearing the bile duct of stones that would otherwise require reoperation.
