Colonic varices are a recognized cause of rectal bleeding in portal hypertension. We report here a patient who presented with melaena several months after resection of an ileal carcinoid tumour. Subsequent colonoscopy for continued episodes of rectal bleeding demonstrated extensive colonic varices. In the absence of portal hypertension, the varices appeared to be related to mesenteric venous obstruction. The management of bleeding colonic varices, in these circumstances, is discussed.
结肠静脉曲张是门静脉高压症患者直肠出血的一个公认原因。我们在此报告一名患者，该患者在回肠类癌肿瘤切除术后数月出现黑便。随后因持续的直肠出血而行结肠镜检查，结果显示广泛的结肠静脉曲张。在没有门静脉高压的情况下，这些静脉曲张似乎与肠系膜静脉阻塞有关。本文讨论了在这种情况下出血性结肠静脉曲张的处理方法。
