Abstract

Experience with the Olympus basket mechanical lithotriptor (BML-1Q) in crushing large common bile duct stones before their endoscopic removal is reported. From January 1988 to January 1990, 68 patients with common duct stones too large to be extracted by Dormia baskets or balloon catheters after sphincterotomy were treated with the BML system. The largest stones in each patient ranged from 1.0 to 4.9 cm in diameter. Fifty-seven patients required one session of lithotripsy, ten patients two sessions and one patient three sessions; 26 patients required further endoscopic extraction of stone fragments after successful lithotripsy. The stones were successfully crushed by the BML system and the ducts cleared in 55 patients (81 per cent). In 13 patients mechanical lithotripsy failed because the stones could not be engaged in the lithotriptor basket. In one patient the stone was crushed with the Soehendra lithotriptor, six patients were successfully managed electrohydraulic lithotripsy through a 'motor and baby' endoscope, indwelling stents were inserted in four patients and two patients underwent surgery.
