[The use of laser ignited mini-explosive technique in treating 100 cases of gastric bezoars]

The experience of breaking gastric bezoars endoscopically with a laser ignited mini-explosive head was reported. After successful application of this technique in vitro and in experimental animals, we began to use it clinically in January 1988. In a period of more than four years, we treated 100 cases of gastric bezoars, 80 cases being male and 20 female, aged from 5 to 65 years. 70 cases were cured after one treatment, 24 after two and the remaining 6 cases after three times of treatment. The cure rate was 100%. Except one case complicated with gastric perforation, no other complications were observed. The etiology and prevention of gastric bezoars, as well as the new method and experience in treating this disease were discussed.
