慢性溃疡性结肠炎患者属结肠癌高危人群,结肠粘膜常有异型增生发生。结肠癌切除标本中也常发现粘膜异型增生,所以异型增生被认为是慢性结肠炎的癌前病变。为此,作者对有全结肠炎7年以上病史的170例病人作了5年多的监视随访研究,着重于异型增生的X线表现。方法:第一年所有病人作结肠双对比造影和结肠镜检查以及多部位的随意活检;第二年重复结肠镜检查和活检;第三年重复结肠双对比造影和直肠、乙状结肠镜检查;第四年以后结肠镜活检和结肠双对比造影交替进行。如果发现异型增生或癌等病情,则予以严密随访、活检或作结肠切除。放射科医师回顾阅读全部病人
Patients with chronic ulcerative colitis are at high risk of colon cancer, colonic mucosa often dysplasia. Colon cancer resection specimens are also often found in mucosal dysplasia, so dysplasia is considered a precancerous lesion of chronic colitis. To this end, the author of more than 7 years with full history of colitis over 170 patients for more than 5 years of follow-up study, focusing on the dysplasia of the X-ray findings. Methods: All patients underwent double contrast colonography and colonoscopy in the first year and random biopsy at multiple sites. The second year of repeat colonoscopy and biopsy, the third year of double colon contrast and rectum and sigmoidoscopy, the fourth Year after colonoscopy biopsy and colon double contrast angiography alternately. If you find that dysplasia or cancer and other conditions, then be closely followed, biopsy or for colon resection. Radiologist reviews all patients read
