Until now, there still has no standard treatment option to deal with gastric bezoars. This respective study was conducted to evaluate the safety and efficiency of Nd:YAG laser-ignited mini-explosive technique for the treatment of gastric bezoars. Two hundred sixty patients with 285 gastric bezoars were treated by endoscopic lithotripsy with Nd:YAG laser-ignited mini-explosive technique. Among the 260 patients, the 284 gastric bezoars of the 259 patients completely disappeared, with the cure rate of 99.6 % after 1–2 treatments at 2–4 weeks follow-up. Only one patient, who was cured by surgery, had gastric perforation during the explosion. No intraoperative or delayed complications was found in the other 259 patients. The endoscopic lithotripsy with Nd:YAG laser-ignited mini-explosive technique is an effective, safe, and promising alternative for gastric bezoars.
