BACKGROUND AND STUDY AIMS: Bezoars are collections of indigestible foreign material that are found within the gastrointestinal tract. Nonoperative approaches such as dietary therapy, enzymatic dissolution, and endoscopic removal have been regarded as the mainstays of therapy. The purpose of this paper is to determine the efficacy of electrohydraulic lithotripsy (EHL) as an alternative form of treatment of @entity356 . @entity1 AND METHODS: Between July 1988 and May 1996, 11 @entity1 with large @entity356 , defined as those greater than 5 cm in diameter, received endoscopic-guided fragmentation using electrohydraulic lithotripsy. Nine of our @entity1 had a history of ingestion of "Pho Pu Zi", (Cordia dichotoma Frost. f.), one of orange pitch, and one of ingestion of persimmon. RESULTS: The 11 @entity1 in the study underwent EHL for the treatment of their @entity356 , with a 100% success rate, which was defined as the lack of residual bezoar seen on post-procedure barium study or endoscopy done 2 days after the procedure. @entity1 were followed-up clinically for 30-68 months, with seven of the 11 @entity1 undergoing a barium study with no residual bezoar noted. No procedure-related complications were seen, except for @entity158 which was most probably secondary to the placement of the @entity6619 overtube. CONCLUSIONS: Endoscopically guided electrohydraulic lithotripsy is a safe, highly effective, alternative nonsurgical technique for the treatment of @entity356 .
