结肠息肉377例临床分析

Analysis on 377 Cascs of Colonic Polyps

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。

In order to understand the realtion of the size, shape, location and single or multiple of colonic polyps to its pathologic type, we made an investigation on 377 petients with colonic polyps dlscovered by endoscopy during recent ten years. The results showed that inflammatory polyps account for the large: majorlty of polyps under 1cm, whereas adenomatous polyps are more than 1cm. Moreover, the over-whelming majortity; of inflammatory polyps is under icm, mainly under 0. 5cm.Malignant polyps are all more than 1cm, especially more than 2cm. Araong polyps with a stalk, inflammatory polyps are very common, whereas among polyps with-out a stalk adenomatou,i polyps are more common. In addition, pedunculatedpolyps are all benign, maligant polyps are all sessile. The large ma jority of polyps occurs in rectum and sigmoid colon. The most common polyps among them are in-flammatory. Among polyps of proximal colon, adenomatolas and malignant polyps are more than others. The large majority of single poiyps is inflammatory, whereas the large majority of multiple polyps is adenomatous. Furthermore, the over-whelming majority of inflammatory polyps is single.
