胃增生性息肉患者合并大肠肿瘤的研究

Association of gastric hyperplastic polyps with synchronous colorectal neoplasia

目的：探讨胃增生性息肉患者合并大肠肿瘤的情况及相关性。方法回顾性分析2011年1月至2013年12月胃增生性息肉患者大肠肿瘤的检出情况，并以同期进行胃镜及结肠镜检查而未发现胃息肉的患者为对照，分析其相关性。结果胃增生性息肉组大肠肿瘤检出率显著高于对照组[24.0％（46／192）比10.4％（40／384），P ＝0.000]，其中以大肠腺瘤增加为主，而大肠癌检出率差异无统计学意义[2.1％（4／192）比2.3％（9／384），P ＝1.000]。分层分析显示，≥50岁的胃增生性息肉患者大肠肿瘤检出率为28.5％（43／151），显著高于对照组10.6％（29／274）（P ＝0.017）。另外，无论胃增生性息肉患者的性别及息肉数量，大肠肿瘤检出均显著高于对照组（P ＜0.05）。结论胃增生性息肉患者尤其≥50岁，无论性别及胃息肉数量，合并大肠肿瘤的比例增高，应及时行结肠镜检查。

Objective To evaluate the association of gastric hyperplastic polyps with colorectal neo-plasia.Methods Data of consecutive patients who underwent esophagogastroduodenoscopy （EGD）and colonoscopy between January 2011 and December 2013 were reviewed retrospectively.They were compared with patients without gastric polyps who also underwent EGD in the same period.The relationship between gastric polyps and colorectal neoplasia was analyzed.Results The incidence of colorectal neoplasia in gas-tric hyperplastic polyps group was higher than that of the control group [24.0% （46 /192）VS 10.4%（40 /384）,P =0.000].An increased incidence of colorectal adenomas in gastric hyperplastic polyps group was found,but there was no difference in the incidence of colorectal cancer in gastric hyperplastic polyps group and control group[2.1%（4 /192）VS 2.3%（9 /384）,P =1.000].Stratification analysis suggested that the incidence of colorectal neoplasia in gastric hyperplastic polyps group who aged over 50 was signifi-cantly higher than that in the control group[28.5%（43 /151）VS 10.6%（29 /274）,P =0.017],regard-less of different genders and the number of gastric hyperplastic polyps.Conclusion The incidence of color-ectal neoplasia in gastric hyperplastic polyps has significantly increased,especially in those aged over 50 years,regardless of different genders and the number of gastric hyperplastic polyps.Such patients should undergo colonoscopy to detect colorectal neoplasia.
