摘要
目的研究内镜下黏膜切除术对平坦型大肠肿瘤的治疗效果,并对其适应证、并发症和操作方法等问题进行讨论。方法有内镜治疗适应证的546例共602处平坦型大肠肿瘤,应用注射法或透明帽辅助法黏膜切除术进行治疗,共切除602个病变,术后定期内镜随访6～73个月,以评价切除效果,记录术中及术后发生的并发症及处理情况,并分析切除标本的病理组织学结果。结果602处病变中588处病变经首次或再次EMR治疗病变完整清除,治愈率为97.7%,术后病理报浸润癌(SM2癌)再追加外科手术者8例(1.3%),因严重并发症(迟发性大出血)转外科手术者2例(0.3%),因病变残留转行外科手术者4例(0.7%)。并发症:术中出血17例(3.1%),均内镜下止血成功,术后迟发出血3例,其中2例(0.4%)内镜下止血失败转外科开腹手术。术后局限性腹膜炎4例,经保守治疗治愈。无穿孔发生。术后病理:黏膜内癌(上皮内高级别瘤变)48例,黏膜下浸润癌10例,类癌37例,良性腺瘤440例,良性间质瘤6例,增生性息肉38例,锯齿状腺瘤10例,B细胞淋巴瘤1例,错构瘤1例,其它3例。结论内镜下黏膜切除术是一种安全微创的内镜治疗手段,对大多数平坦型大肠肿瘤能达到完全切除效果。
Objective:To investigate the curative effect on endoscopic mucosal resection(EMR) for colorectal flat tumors and to discuss the applications,complications and techniques of this procedure.Methods:A total of 546 patients with 602 lesions were included in this study.EMR were performed by means of en bloc either injection snare cut method.The follow-up period was 6~73 months to evaluate the curative effect.The rates of complications and following treatments were recorded.All resected specimens were retrieved f...
