大肠息肉部位、大小、形态等与病理分型的关系

目的探讨大肠息肉部位、大小、形态、数目部与病理类型的关系。方法经结肠镜检查诊断200例结肠息肉情况与病理检查进行分析。结果在≤1cm的息肉中以炎性息内较多见，在〉lcm的息肉中以腺瘤性息肉较多见。息肉恶变均发生在1cm以上，尤其是〉2cm的息肉。在有蒂息肉中以炎性较多见，均为良性，无蒂息肉中以腺瘤性较多见。最常发生于直肠和乙状结肠的息肉以炎性较多见；近端结肠的息肉，腺瘤性相对较多。单发息肉中多数是炎性息肉，多发息肉中多数是腺瘤性息肉。结论大肠息肉的部位和大小与病理类型有关。

Pathologic characteristics of colorectal polyp

AIM To explore the histo- and anatomico- pathological characteristics of colorectal polyp for a better understanding of the disease. METHOD Two hundred patients with colorectal polyps pathologically confirmed in the last ten years were reviewed. RESULTS Inflammatory polyps accounted for .55.3% and adenomatous polyps accounted for 36.0% of polyps of less than 1 cm in diameter,and 22.0% and 40.0% of larger polyps, respectively. All 1.5 malignant polyps were more than 1 cm. Pedunculated or solitary polyps were usually inflammatory, which were often found in sigmoid colon and rectum. Sessile or multiple polyps were usually adenomatous,which were usually located at proximal colon. CONCLUSION The location and size of colorectal polyps can give some hint about the pathologic type of the polyps.
