Longstanding ulcerative colitis, particularly pancolitis, is associated with an increased risk of colorectal neoplasia. For this reason surveillance colonoscopy at regular intervals has been recommended to identify early cancers or high grade dysplasia. Three cases are described of patients with ulcerative colitis of greater than 10 years duration who presented with colorectal carcinoma within three years of colonoscopy.
长期溃疡性结肠炎，尤其是全结肠炎，与结直肠癌风险增加相关。因此，建议定期进行结肠镜监测以发现早期癌症或高级别异型增生。本文描述了3例溃疡性结肠炎病程超过10年的患者，他们在结肠镜检查后3年内出现了结直肠癌。
