【摘要】 〔目的〕探讨健康体检者进行结直肠镜检查的临床意义。〔方法〕回顾性分析我院接受结肠镜检查的532例健康体检者的临床资料,分析其结直肠病变的临床特征。〔结果〕532例无症状健康体检者中,130例发现结直肠黏膜病变,检出率为24.4%;结直肠息肉63例,检出率为11.8%;发现早期结肠癌3例(分期均为早期,无远处转移)。117枚息肉中,以管状腺瘤居多,以直径<0.5 cm的息肉为主。男性息肉检出率(15.5%,48/309)显著高于女性(6.7%,15/223);女性结肠黑变病检出率(6.28%,14/223)显著高于男性(0.65%,2/309)。息肉检出率、中-重度不典型增生及结肠黑变病随年龄增长呈上升趋势,≥50岁年龄组体检人群息肉检出率、中-重度不典型增生及结肠黑变病显著高于<50岁年龄段人群。〔结论〕结直肠息肉是无症状健康体检者的主要结肠病变,男性、年龄≥50岁者结肠息肉及中-重度不典型增生检出率高。结肠镜是筛查结直肠病变,特别是结肠癌早期,最为有效安全的手段。更多还原

【Abstract】 〔O bjective〕To investigate the clinical significance of colonoscopy examination in the asymptomatic healthy subjects.〔Methods〕Using retrospective analysis, 532 cases calculated in our hospital with asymptomatic healthy subjects have received colonoscopy examination and, and its clinical characteristics of colorectal lesions were analyzed. 〔R esults〕532 cases with asymptomatic healthy subjects received colonoscopy examination, of which 130 cases have the colorectal mucosa lesions. The detection rate of colorectal mucosa lesions was 24. 4%. and 63 cases infected with colorectal polyps andthe detection rate of colorectal polyps was 11. 8%. only three cases of colon cancer( early stage without distant metastasis) were found out. In all of117 polyps, the tubular adenoma and the polyp diameter less than < 0. 5cm are in the majority. The male polyp detection rate( 15. 5%, 48/309) was significantly higher than that in female( 6. 7%, 15/223). the female melanosis coli detection rate( 6.28%, 14/223) was significantly higher than that of male( 0. 65%, 2/309). Along with the age growth, the polyp detection rate, severe atypical hyperplasia and colon melanosis are raised. with more than 50-year-old age group, the polyp detection rate,moderate to severe atypical hyperplasia and melanosis coli were significantly higher than that of the people of less than 50 years of age. 〔C onclusion〕The colorectal polyps are the main lesion with the asymptomatic healthy subjects. The detection rate with colorectal polyps and moderate-severe atypical hyperplasia are higher in the male and more than 50 years old group. Colonoscopy is the most effective and safe method for the screening of colorectal lesions, especially in the early stage of colorectal cancer.更多还原
