摘要目的 分析电子直乙结肠镜在健康体检中的检查结果.方法 对我院体检中心2010年5月至2013年12月30 250名健康体检者(其中男性18 842名,女性11 408名)电子直乙结肠镜检查筛查出的直肠及乙状结肠疾病检出率进行回顾性分析.研究中计数资料的描述采用2×C表线性回归的x2检验.结果 在电子直乙结肠镜检查中发现疾病22 035名,检出率为72.84％,其中常见疾病如下:痔疮55.57％(16 810/30 250),直肠息肉10.57％(3 196/30 250),肛乳头肥大5.03％(1 523/30 250),直肠炎0.69％(210/30 250),肛裂0.54％(162/30 250),直肠黑变病0.29％(87/30 250),直肠癌0.09％(28/30 250),肛管息肉0.04％(13/30 250),肛瘘0.02％(6/30 250).男性直乙结肠息肉检出率13.09％,女性直肠息肉检出率6.04％;男性直乙结肠癌检出率0.12％,女性直肠癌检出率0.05％.结论 电子直乙结肠镜检查对直肠息肉、直肠癌、直肠黑变病、直肠炎的检出率高于肛门指诊.

abstractsObjective To investigate the value of electronic rectosigmoidoscopy in health examinations.Methods Based on retrospective analysis of 30 250 patients who received electronic rectosigmoidoscopy in the Physical Examination Center of our hospital from May 2010 to Dec.2013,the incidence of anal disease and sigmoid colon disease were analyzed.Results The highest detection rate of common diseases was hemorrhoids,followed by proctopolyps,hypertrophy of anal papilla,proctitis,anal fissure,melanosis coli and colonic tumor.The detectable rate of them were 55.57％ (16 810/30 250),10.57％ (3 196/30 250),5.03％ (1 523/30 250),0.69％ (210/30 250),0.54％ (162/30 250),0.29％ (87/30 250),0.09％ (28/30 250),0.04％ (13/30 250),0.02％ (6/30 250).Conclusion Electronic colonoscopy for colorectal polyps,rectal cancer,colon melanosis and proctitis detection rate was significantly higher than the anus digital rectal examination,the difference is statistically significant,and it also has merits of simplicity,noninvasiveness and rapidity.
