目的:研究息肉间变的相关因素。方法:总结529例息肉及其中伴异型增生或恶变息肉的分布、大小及病理资料。结果:529个息肉异型增生达30.81%,息肉恶变达3.02%,好发于左半结肠。异型增生及恶变息肉随息肉增大而增加,息肉恶变率直径0.6～1.0cm者为12.5%,1.1～1.9cm为12.5%,≥2.0cm为75%,腺瘤性息肉明显多于非腺瘤性息肉,其异型增生为59.62%,恶变率为5.92%,非腺瘤性息肉异型增生0.77%,恶变率为0,其中,腺瘤中又以绒毛状腺瘤及绒毛管状腺瘤的异型增生及癌变最多见。结论:息肉间变与息肉的大小、形态和类型有密切关系。
Objective: To study the related factors of polyp changes. Methods: The distribution, size and pathology of 529 cases of polyps and their associated dysplastic or malignant polyps were summarized. Results: The polyps of 529 polyps were 30.81% dysplasia and 3.02% polyps were malignant, which occurred in the left colon. Dysplasia and malignant polyps increased with the polyps increased, polypoid degeneration rate of 12.5% in diameter 0.6 ~ 1.0cm, 1.1 ~ 1.9cm 12.5%, ≥ 2.0cm 75%, adenomatous polyps were significantly more than non-adenoma Polyps, the dysplasia was 59.62%, the rate of malignant transformation was 5.92%, non-adenomatous polypoism dysplasia 0.77%, the rate of malignancy was 0, of which adenoma and villous adenoma and villous tubular adenoma dysplasia And the most common cancer. Conclusion: The relationship between polyps and the size, shape and type of polyps are closely related.
