53例大肠息肉癌变分析

本组大肠息肉５４８例，８１５枚，５３例（枚）癌变，癌变率９．７％．以乳头状腺癌、混合腺瘤癌变率较高，二者间无差异（Ｐ＞０．０５），管状腺瘤较低，与前二者差异明显（Ｐ＜０．０１），且发现１例炎性息肉癌变．直径＞２．ｏｃｍ，息肉癌变率明显高于２．０ｃｍ以下者（Ｐ＜０．０１）．广基息肉癌变率高于带蒂者（０．０５＞Ｐ＞０．０１）．癌变息肉表面色泽均有改变．在儿童期未检出癌变息肉；中年期息肉癌变率高于青年期（Ｐ＜０．０５），而与老年期无差异（Ｐ＞０．０５）．各大肠段息肉癌变率无差异（Ｐ＞０．０５）．内镜检查并取材活检明显提高了息肉及其癌变的检出率，内镜下治疗息肉可降低大肠癌的发病率．

A analysis of polyps canceration in 53 patients with polyps of large intestine

cases with 815 large intestinal polyps were analysed. The results were as follow: Polyps canceration was found in 53 cases (9.7%). Among which the canceration rate was significantly higher in villous and mixed polyps than in tubular polars (P0. 05). There was canceration with inflamed polyps. The canceration rate of polyps with larger than 2cm in diameter was higher than those with smaller than 2cm in diameter (P<0. 01 ). The canceration rate of the polyps with wide fundus were higher than those with pedide (P<0. 05). The colour of surface with the canceration polyps was changen. No canceration of polyps was found in children. The canceration rate of polyps in the middle-aged was higher than in the young (P<0. 05), and was as same as in the old (P>0. 05). The canceration rate of polyps in different segment of large intestine was similiar (P>0. 05). Endoscopy and biopsy advanced markedly the diagnostic rate of polyps and their canceration. Endoscopic treatment may decrease the canceration of polys.
