内镜套扎治疗结肠黏膜下肿瘤40例

目的:评价结肠黏膜下肿瘤内镜套扎治疗的临床效果.方法:对我科40例结肠黏膜下肿瘤(submucosaltumors,SMT)(肿瘤直径≤19 mm)行超声内镜检查(endoscopic ultrasonography,EUS)并作出初步诊断,之后采取结肠镜下套扎技术进行治疗,且术后回收病变组织,定期复查,随访术后有无并发症及套扎术的疗效.结果:40例患者黏膜下肿瘤均完整清除,6例采用单纯结肠镜下套扎技术,34例采用结肠镜下套扎联合高频电切术治疗,34例回收的组织病理显示:12例为脂肪瘤,12例为类癌,8例为间质瘤,2例为平滑肌瘤.结论:内镜下套扎技术对于结肠黏膜下肿瘤的治疗是一种安全、可行的方法,能够对病灶进行有效清除,对于结肠肿瘤的早期防治起到重要作用.

Treatment of submucosal tumors of the colon by loop ligature: an analysis of 40 cases

AIM: To assess the efficacy and safety of nylon endoloop ligature or combined nylon endoloop ligature with colonoscopy-assisted high-frequency electric snare in the treatment of submucosal tumors of the colon. METHODS: Forty patients who were diagnosed with submucosal tumors of the colon by endoscopic ultrasonography and treated by nylon endoloop ligature were included in this study.In some cases,combined nylon endoloop ligature with colonoscopy-assisted high-frequency electric snare were performed to take samples and remove lesions completely.The pathologic data for these patients were analyzed. RESULTS: All cases of submucosal tumors of the colon were removed after nylon endoloop ligature.Pathological samples were taken from 34 patients,of whom 12 had lipomas,12 had carcinoids,8 had stromal tumors and 2 had leiomyomas.No complications occurred. CONCLUSION: Nylon endoloop ligature or combined nylon endoloop ligature with colonoscopy-assisted high-frequency electric snare is an effective and safe method for removing submucosal tumors of the colon.
