Abstract
We used EHL, snare and mechanical lithtriptor (ML), whitch was used for stones in the common bile duct, to crush bezoar due to ingestion of "mamekaki" (berries of a japanese persimon) and stones came out from the anus, while the concurrent gastric ulcer was also treated. Case : 71-year-old female. Gastroscopy and gastric X-ray film revealed 2 gastric bezoar, 5.6×5.4×5.0 cm and 5.0×6.0×5.2 cm in size respectively, and stage A2 gastric ulcer existed at the angulus. Gastric bezoars were removed using Olympus Lithotron EL21 and the one channel fiber-scope XK20. The bezoars were then divided by a snare, and fragmented to less than 2 cm with ML. Later, the crushed bezoars were found in feces. Gastric ulcer healed to S1 stage in about 2 weeks after treatment. EHL seemed to have an advantage compared to a conventional snare or laser treatment, because it took only 45 min, and it could be used with a one-channel fiberscope, and was safe.
