We have been performing bile duct lithotripsy by EST at Kumamoto Regional Medical Center since January 1982. A balloon catheter is the method of choice for performing lithotripsy. For stone removal, a conventional FG‐22Q basket catheter was used from January 1982 to June 1984 (extraction rate: 88.5%), and a prototype EML BML‐1Q basket catheter was used with a FG‐22Q basket catheter from July 1984 to April 1990 (extraction rate: 91.5%). Since May 1990, lithotripsy has been performed in the following sequence with excellent results (extraction rate: 97.0%): EST‐balloon catheter, slide‐type EML BML‐3Q‐balloon catheter. Although the difference between the extraction rates for BML‐1Q and BML‐3Q basket catheters were only marginally significant, the difference between the conventional basket FG‐22Q and BML‐3Q was clearly significant. Lithotomy using the procedure employed since May 1990 is therefore recommended as a highly effective means of extracting gallstones and is considered to be superior to conventional methods.
