较大比例的右半结肠癌由锯齿状息肉癌变而来,结肠镜检仅能有限预防结肠癌。为了比较帽辅助结肠镜和标准结肠镜对锯齿状息肉的检查,Rzouq F等人对427例患者(7例排除,210例完成配对研究,平均年龄61岁,95%为男性,75%为白人,67%行结肠镜筛查)采用随机对照试验方法,比较了标准和帽辅助结肠镜检查对腺瘤的检出率。两种方法的锯齿状息肉检出率使用Fisher’s精确检验和Wilcoxon秩和检验。两种方法检测患者的基线特征差异无统计学意义。帽辅助结肠镜相对标准
A large proportion of right-sided colon carcinomas result from cancerous polyps, and colonoscopy is limited to prevent colon cancer. Rzouq F et al. Compared 427 patients (7 excluded, 210 completed the paired study, mean age 61 years, 95% men, 75% white in order to compare serrated polyps with cap-assisted colonoscopy and standard colonoscopy. , 67% colonoscopy screening) using a randomized controlled trial comparing standard and cap-assisted colonoscopy for detection of adenomas. The jagged polyp detection rates for both methods were Fisher’s exact test and Wilcoxon rank sum test. There was no significant difference in baseline characteristics between the two methods. Cap-assisted colonoscopy relative standard
