超声内镜指导下黏膜下挖除术治疗胃固有肌层间质瘤

目的 观察超声内镜指导下黏膜下挖除术治疗胃固有肌层间质瘤的疗效及安全性.方法 经超声内镜初步诊断为来源于胃固有肌层的间质瘤19例,超声内镜明确病变来源、回声、大小、血供等情况后行黏膜下挖除治疗,观察其疗效及并发症.结果 18例病变完整挖除,1例挖除失败.术中出现穿孔2例,经钛夹封闭创面治愈.术中有少量出血,经热活检钳钳夹或氩气凝固止血,出血停止.无迟发性出血.结论 黏膜下挖除术治疗胃固有肌层间质瘤安全有效,术前行超声内镜检查进行严格评估具有重要价值.

Endoscopic ultrasonography submucosal resection for treatment of gastric muscularis propria mesenchymal tumor

Objective To observe the efficacy and safety of endoscopic ultrasonography submucosal resection for treatment of gastric muscularis propria mesenchymal tumor.Methods Endoscopic ultrasonography preliminary diagnosis of 19 cases were diagnosed stromal tumors originating from gastric muscularis propria layer,the endoscopic ultrasonography diagnosis the source,echo,size,blood supply,etc.than treated by endoscopic submucosal excavation.To observe the therapeutic effect and complications.Results Eighteen patients were the full excavation,1 patient was failed.Intraoperative perforation was seen in 2 cases,the wound was healed by the titanium clamp.A small amount of bleeding happened in operation and bleeding was stopped by hot biopsy forceps or argon coagulation.No delayed bleeding happened.Conclusion Submucosal resection for gastric muscularis propria mesenchymal tumors is safe and effective,endoscopic ultrasonography has important value in the strict assessment.
