2485例常规结肠镜筛查结肠息肉检出情况分析

Analysis of colon polyps in 2485 cases by screening colonoscopy

目的了解不同性别和年龄者结肠息肉发病情况。方法按性别、年龄、发病部位以及病理学结果等因素对该院接受常规结肠镜检查的2 485例患者结肠息肉及结肠癌发病情况进行分析。结果 2 485例患者中结肠息肉检出率为35.6%,结肠癌检出率为5.8%,其中男性结肠息肉检出率为40.9%,结肠癌检出率为7.7%;女性结肠息肉检出率为30.5%,结肠癌检出率为3.9%。检出率随着年龄而增加,结肠息肉及结肠癌检出高峰均在70岁年龄组,50岁以上年龄组男性结肠息肉及结肠癌检出率均明显高于女性(P<0.01)。息肉以炎性息肉为主,腺瘤性息肉次之,以左半结肠为主。结论结肠息肉是年龄相关性疾病,其存在年龄及性别差异,男性结肠息肉及结肠癌检出率高于女性,男女性结肠息肉及结肠癌检出率均随年龄增长而增加,男女40岁以上息肉检出率明显升高,对40岁以上有肠道症状者应进行结肠镜筛查。

[Objective] To study the incidence of colon polyps in different gender and age. [Methods] We analyzed the colon polyps and cancer in 2485 patients received colonoseopy by gender, age, disease location and pathology results and other factors. [Results] In 2485 patients, the detection rate was 35.6% in colon polyp, 5.8% in colon cancer. In male the detection rate was 40.9% in colon polyp, 7.7% in colon cancer; In female the detection rate was 30.5% in colon polyp, 3.9% in colon cancer; the prevalence was increased with age, and the peak detection of colon polyp and cancer were 70 years old age group. Over 50 years old, the detection rate of colon polyps and cancer were higher in male than female（P 〈0.01）. The colon polyps were dominated by inflammatory polyps, followed by adenomatous polyps, mainly in the left colon. [ Conclusion ] Colon polyps are age-related diseases. The detection rate of colon polyp and cancer were higher in male than female. Men and women over 40 years old polyp detection rate was significantly higher. So over 40 years old who have intestinal symptoms should be received screening colonoscoov.
