内镜下黏膜切除术治疗结直肠肿瘤

目的用内镜下黏膜切除术(EMR)治疗早期大肠癌及癌前病变,探讨病变大体分型和表面形态与病理组织学分型之间的关系。方法2002年12月-2004年12月共完成结直肠肿瘤EMR手术58例(其中男性49例,女性9例,平均年龄65．8岁),共计70个病变,对切除标本进行常规病理组织学观察。术后内镜随访1～23个月。结果70个病灶均为完全切除,除3例发生可控制出血外,未发生其他与手术相关的并发症。病理报告：3个病灶为早期癌,53个为腺瘤伴1～3级异型增生,其余14个均为炎性增生。随访期间所有病例均无复发。结论EMR可作为治疗黏膜层及黏膜下浅层早期大肠癌或癌前病变的方法。

Endoscopic mucosal resection for the treatment of colorectal tumors

Objective To further study the effectiveness of endoscopic mucosal resection (EMR) for the treatment of early cancer and precancerous lesions on colon and rectum. Methods A total of 58 patients with 70 lesions were included in this study. EMR were performed by means of " injection and cut " method. Results All the lesions were resected completely by EMR. All the diagnoses were proved by pathology as follows: mucosal cancer 3 cases, adenoma with mild to severe dysplasia 53 cases, and inflammatory polyps 14 cases. No recurrence was found during the follow up survey for 1 23 months. Except 3 cases of treatable hemorrhage, no other complications were found. Conclusion The results of this study further confirm that EMR is effective and safe for the treatment of early cancer and precancerous lesions on colon and rectum
