目的：探讨慢性炎症后的大肠多发性息肉的 Ｘ线特征及其进一步发展趋向。材料和方法：对 ５８例大肠多发性息肉的Ｘ线表现特征与临床、病理及内窥镜所见进行对照分析。结果：５８例大肠多发炎性息肉全部由溃疡性结肠炎发展而来，其中肉芽肿性息肉３２例；纤维性息肉１９例；腺瘤性息肉５例；腺瘤性息肉伴少许癌细胞浸润２例。结论：（１）大肠多发炎性息肉是由于慢性炎症刺激所致的肉芽组织、纤维组织及腺体组织增生混合而成，少数可发生恶变；（２）在大肠慢性炎症中，以溃疡性结肠炎最易导致多发炎性息肉及腺瘤性息肉形成；（３）Ｘ线双重造影检查显示除典型慢性炎症征象外，多发息肉形似“蟾蜍皮”或“蜂窝状”结肠双对比征象是其特征。
OBJECTIVE: To investigate the X-ray characteristics of multiple polyps of the large intestine after chronic inflammation and its further development trend. Materials and Methods: X-ray findings of 58 cases of multiple polyps of large intestine were compared with clinical, pathological and endoscopic findings. Results: All the 58 cases of multi-inflammatory polyps of large intestine developed from ulcerative colitis, including 32 cases of granulomatous polyps, 19 cases of fibro-polyps, 5 cases of adenomatous polyps, 2 cases of adenomatous polyps with a little cancer cell infiltration 2 example. Conclusions: (1) Multiple inflammatory polyps in the large intestine are caused by the proliferation of granulation tissue, fibrous tissue and glandular tissue due to the chronic inflammatory stimuli. A small number of malignant polyps may be malignant. (2) In the chronic inflammation of the large intestine, ulcerative colon Inflammation most easily lead to polyinflammatory polyps and adenomatous polyps formation; (3) X-ray double contrast examination showed that in addition to the typical signs of chronic inflammation, multiple polyp form of “toad skin” or “honeycomb” double colon contrast signs is characterized .
