为了解大肠息肉的大小。形状、部位以及单发或多发与病理类型的关系，对我院经结肠镜检出的大肠息肉377例进行了分析。结果表明。在≤1cm。的息肉中以炎性息肉较多见，在＞1cm的息肉中以腺癌性息肉较多见。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癌性息肉。
To understand the size of colon polyps. The shape, location, and the relationship between single or multiple and pathological types were analyzed in 377 cases of colorectal polyps detected by colonoscopy in our hospital. The results show. In ≤ 1cm. In polyps, inflammatory polyps are more common, and in polyps >1cm, adenocarcinoma polyps are more common. Polyps occur in more than 1cm malignant, especially >2cm polyps; in pedunculated polyps more common in inflammation. All were benign; adenomas were more common in sessile polyps. The polyps that most commonly occur in the rectum and sigmoid colon are more inflammatory; the polyps of the proximal colon are relatively more adenomas; the majority of single polyps are inflammatory polyps, and most of the polyps are adenocarcinoma polyps.
