摘　　要：目的探讨胃镜下U-100双频双脉冲掺钕钇石榴石(Nd:YAG)激光对难治性胃石的治疗的安全性和有效性。方法应用U-100双频双脉冲掺钕钇石榴石(Nd:YAG)激光经胃镜治疗难治性胃石。结果总碎石成功率100%,激光平均工作时间:10787 J能量,碎石时间在94 min。结论双频双脉冲掺钕钇石榴石(Nd:YAG)激光治疗难治性胃石,是一种高效、安全、操作简便,组织损伤甚微的手术方法。Objective We aimed to find a new way to manage the gastric bezoar which polypectomy snare and other management does not work. Methods U-100 frequency-doubled double- pulse Neodymium： YAG （Nd： YAG） laser was used to disrupt the refractory gastric bezoar shell through the upper gastrointestinal endoscopy. Results All bezoar shell was disrupt by U-100 frequency-doubled double-pulse Nd： YAG laser. Conclusion U-100 frequency-doubled double-pulse Nd. YAG laser is a safe efficient and useful way to manage refractory gastric bezoar.
