内镜下橡皮圈套扎治疗消化道黏膜下良性肿瘤47例

Loop ligature with a rubber band under endoscope for treatment of benign tumor under mucosa in alimentary tract

目的:探讨内镜下橡皮圈套扎治疗上消化道黏膜下良性肿瘤的可行性和疗效。方法:47例直径<1.5 cm的消化道黏膜下良性肿瘤,经胃镜、超声胃镜及镜下穿刺病理检查排除恶变后行内镜下套扎治疗。胃镜端部连接食管静脉曲张套扎器(透明帽),插入上消化道找到黏膜下良性肿瘤,负压将其吸引入透明帽内,释放橡皮圈,黏膜下良性肿瘤即被套扎。复查胃镜观察疗效。结果:黏膜下良性肿瘤完全脱落。脱落处黏膜形成表浅溃疡,1～2周后溃疡愈合。无一例出现腹痛、恶心、呕吐、出血、穿孔、感染等并发症。结论:内镜下橡皮圈套扎治疗消化道黏膜下良性肿瘤效果好,安全性高。

Objective：To study the feasibility and therapeutic effect of loop ligature with a rubber band under endoscope in treatment of benign tumors under mucosa in the alimentary tract.Methods：Forty-seven cases of benign tumors with a diameter of less than 1.5 cm under mucosa in the alimentary tract were performed by loop ligature with a rubber band under endoscope after being precluded of canceration by gastroscope,ultrasonic endoscope and pathology biopsy.The loop ligature（hyaline cap） was,connected to the head of the gastroscope,the benign tumor under mucosa in the alimentary tract was drawn into the hyaline cap with underpressure before releasing the rubber band,and then the benign tumor was loop-ligatured.The therapeutic effect was evaluated several days later.Results：The benign tumor ablated completely;a superficial anabrosis was formed in the mucosa,and cicatrized within one or two weeks.No one presented abdominal pain,vomit,hemorrhage,perforation or infection.Conclusions：The procedure of loop ligature under endoscope with a rubber band is easy and safe for treatment of benign tumors under mucosa in the alimentary tract.
