摘　　要：目的:总结大肠平坦型病变的临床特征,以探讨对大肠腺瘤的诊断和治疗。方法:回顾性分析大肠隆起型和平坦型病变,对其好发年龄、发生部位、直径、病理进行比较。结果:2966例患者中检出大肠病变939例,隆起型病变占58.68%(551/939),平坦型病变占11.29%(106/939)。平坦型病变的平均年龄为(51±13.65)岁,隆起型病变平均年龄为(47±16.41)岁。平坦型病变直肠占33.96%,隆起型病变的直肠占21.786%。平坦型病变直径为(17±9.7)mm,隆起型为(28±7.3)mm。平坦型病变癌变率为4.72%,隆起型为3.09%。结论:大肠平坦型病变有恶变潜能,对其早期诊断和积极治疗,势必会降低大肠癌的发生率。Objective To study the clinical character of flat colorectal lesions in order tO explore the diagnosis and therapy. Methods The age, location, diameter, pathologic type of colorectal flat lesions and polyp lesions were analyzed and compared. Results A total of 939 lesions were found colorectal; 106（11.29%）were flat lesions; 551 were protruded lesions. The mean age of flat lesions was （51±13.65） years, and that of polyp lesions was （47±16.41） years. The flat lesions and polyp lesions accounted for 33.96% and 21.78% respectirely. The mean diameter of flat lesions was （17± 9.7） mm, which was significantly less than that of polyp lesions （28±7.3） mm. The canceration rate of flat lesions and polyp lesions were 4.72% and 3.09%, respectively. Conclusion The flat colorectal lesion is a common disease. It is cancerogenic. Early diagnosis and active therapy could decrease the rate of carcinoma of large intestine.
