目的探讨大肠息肉的组织分型、癌变及其防治途径。方法收集分析402例大肠息肉患者的大肠镜检查、病理结果、大肠镜下高频电切除的疗效、并发症及随访。结果78.9%腺瘤性息肉分布在直肠、乙状结肠;腺瘤性息肉癌变达12.2%;高频电切除术后原息肉不复发,并发肠出血19例,无1例穿孔。结论大肠镜检及高频电切除术在防治大肠息肉恶变中具有重要作用,乙状结肠镜检在乡、镇卫生院替代大肠镜检值得推广,高频电切除术是大肠息肉的一种高效、安全的治疗方法。
Objective To investigate the histological type, carcinogenesis, and prevention and treatment of colorectal polyps. METHODS: Colonoscopy, pathological findings, curative effect, complications, and follow-up of colonoscopy were collected and analyzed in 402 patients with colorectal polyps. Results 78.9% of adenomatous polyps were distributed in the rectum and sigmoid colon; the cancerous rate of adenomatous polyps was 12.2%; the polyp did not relapse after high-frequency electric resection, 19 cases had complicated intestinal bleeding, and none had perforation. Conclusion Colonoscopy and high-frequency electric resection have an important role in prevention and treatment of colorectal polyps. Sigmoid colonoscopy is worthy of popularization in the replacement of colonoscopy in township and township hospitals. High-frequency electric resection is an efficient and safe method for colorectal polyps. Therapeutic methods.
