The extracorporeal shock wale lithotriptor, ESL-500A, has a two-way approach applicator. The conventional under-abdomen approach and a new over-head approach with the ESL-500A were thus compared for the treatment of cholecystolithiasis. Effective rates were 53.9 % (14/26) and 44.4 % (4/9), respectively. Moreover, stone free rates were 15.4 % (4/26) and 11.1 % (1/9), not significantly different. However, gall bladder wall thickness could be determined more accurately with the underabdomen approach,30.8 % (8/26), than with over-head approach,22.2 % (2/9). The anti-miss-shot control device decreased the degree of gall bladder wall change in both groups. The ESL-500A, with its two-way approach applicator and anti-miss-shot control device, is thought to be safe and to broader the indications for extracorporeal shock wave lithotripsy (ESWL) treatment of cholecystolithiasis.
