目的 探讨大肠息肉的分布、大小、形态和病理特征及内镜治疗措施。方法 对结肠镜检出的大肠息肉患者的临床表现、内镜及病理资料进行回顾性分析。结果 结肠镜大肠息肉的检出率为 2 1 2 % ,其中 74 3 %为腺瘤性息肉 ;息肉分布以直肠和乙状结肠为最多 ;息肉癌变者均为腺瘤性息肉 ;腺瘤体积越大、呈分叶或菜花形、无蒂或广基、含绒毛成份越多者 ,越易发生癌变 ;高频电凝摘除息肉 713例 ,并发症发生率为 0 4%。结论 腺瘤癌变与体积大小、形态、绒毛成份含量等因素相关 ;息肉不论大小应尽可能予以切除 ;电凝摘除息肉安全有效 ,是大肠息肉首选的治疗方法。
Objective To investigate the distribution, size, morphology, pathology and endoscopic treatment of colorectal polyps. Methods The clinical manifestations, endoscopic and pathological findings of colorectal polyps detected by colonoscopy were analyzed retrospectively. Results The detection rate of colorectal polyps was 2 1 2%, of which 74 3% was adenomatous polyps. Polyps were mostly distributed in the rectum and sigmoid colon. The polyposis carcinomas were all adenomatous polyps. Was lobulated or cauliflower-shaped, pedicle-free or broad-based, containing more villi components, the more prone to cancer; high frequency coagulation removal of polyps in 713 cases, the complication rate was 04%. Conclusions Adenoma carcinogenesis is related to the size, shape and content of villus. Polyps should be resected to the maximum extent possible, and the removal of polyps by electrocoagulation is safe and effective. It is the first choice for the treatment of colorectal polyps.
