Objective:To evaluate the clinical value of endoscopic treatment for large polyps in rectum and colon. Methods: The clinical data of 89 cases of large colorecta polyps treated with endoscopic resection from June 2007 to December 2010 was analysed retrospectively. Results: All 94 polyps in 89 cases were removed completely, including 20 thick-pedunculated or sessile polyps and 9 laterally spreading tumor. All lesions were larger than 2cm, and the largest one was 5. 5cm. Bleeding occurred in 6 patients after resection (6. 7%). Perforation occurred in 2 patients (2. 1%) All complications were treated endoscopically. Histopathology results showed that adenoma was 75 (85. 5%) , hyperplastic polyps 13 and carcinoma 6, include 4 cases of mu-cosal carcinoma. During a meaning follow-up period of 16 months, 3 patients with adenoma developing recurrences were treated endoscopically. No more residual tumor was detected in next following-up. Conclusions: Endoscopic resection of large rectal polyps is a safe and effective technology.%目的:探讨内镜下切除结直肠大息内的临床价值.方法:回顾分析2007年6月-2010年12月行内镜下切除的89例结直肠大息肉患者的临床资料.结果:89例患者患有大息肉94枚,其中亚蒂或广基20枚,侧向发育型肿瘤9枚,息肉最大直径为2.0～5.5 cm;所有息肉均在内镜下完整切除,并发出血6例,穿孔2例,并发症均在内镜下处理成功；术后病理诊断:腺瘤性息肉75枚(79.8％),炎性增生息肉13枚(13.8％),腺癌6枚(6.4％),其中黏膜内癌4枚.术后3例腺瘤患者复发,再次行内镜下切除,随访无复发.结论:内镜下行结直肠大息肉切除安全可靠、创伤小、疗效确切.
