目的观察超声内镜指导下套扎器套扎治疗胃间质瘤的效果。方法选取经超声内镜检查诊断胃黏膜下来源于胃固有肌层的小间质瘤45例,瘤体直径0.5～1.3 cm,以六连环套扎器行内镜下间质瘤套扎治疗,套扎后用超声内镜观察间质瘤是否套入圈套中。术后观察有无出血、穿孔等并发症。术后1～3月复查胃镜以了解愈合情况。结果胃黏膜下来源于固有肌层小间质瘤45例中,位于胃底32例,胃体11例,胃窦2例。7例行细针穿刺组织病理及免疫组化结果证实为黏膜下间质瘤。行胃黏膜下间质瘤的套扎术,成功44例,成功率97.8%。3例术后黑便,无一例发生穿孔。结论在超声内镜指导下对胃黏膜下固有肌层小间质瘤行套扎术,方法简便、安全、有效,并发症少,值得临床广泛应用。
Objective To observe the effect of ultrasound-guided endoscopic ligation in the treatment of gastric stromal tumors. Methods Forty-five small interstitial tumors were diagnosed by endoscopic ultrasonography in the gastric mucosa from the gastric muscularis propria. The diameter of tumor was 0.5 ~ 1.3 cm. The endoscopic stromal tumor was ligated with a six- After ligation with ultrasound endoscopy to see whether interstitial tumor trapped in the trap. Postoperative observation of bleeding, perforation and other complications. 1 to 3 months after the review gastroscopy to understand the healing. Results The gastric mucosa was originated from 45 cases of intrinsic muscular small interstitial tumor, 32 cases were located in the fundus, 11 cases were gastric body and 2 cases were gastric antrum. Seven cases of fine needle aspiration histopathology and immunohistochemistry results confirmed as submucosal tumor. In gastric mucosal stromal tumor ligation, the success of 44 cases, the success rate of 97.8%. 3 cases of melena, no case of perforation occurred. Conclusion Under the guidance of endoscopic ultrasonography, the gastric mucosa of small myxomas with lamina propria can be lined easily. It is safe, effective and has fewer complications. It is worth widely clinical application.
