结肠血管扩张症

结肠血管扩张症是下消化道出血原因之一，其病理特点是粘膜下血管异常扩张，瘀血及多灶性粘膜出血，多发生于老年人，是血管退行性变所致。报告手术治疗７例，２例术后发生了再出血，系由于内镜，血管造影及手术探查所见病变部位不一致，而术后过于相信手术所见，忽略了该病的病理特点，廷民切除范围不够，术后发生再出血。

Vascular ectasias of the colon

Colon vascular ectasias(CVE),a degenerative lesions associated with aging,is one of the causes of lower intestinal tract bleeding.The pathological characteristics of CVE are submu cosal vessel dilation and distortion, thin-walled and multiple hemorrhagic lesions.Identification of hemorrhage depends mainly on colonoscopy,angiography and laparotomy.The curative therapy is the adequate resection of diseased segments. But preoperative colonoscopy,angiography and laparo tomy sometimes can't match each other on the bleeding location, and surgeons overestimated and relied on one of them,then inadequate resection followed by postoperative rebleedings.We report ed 7 cases with surgical intervention and 2 of them have postoperative rebleeding caused by factors mentioned above.Hence we should have comprehensive evaluation of colonoscopy,angiography and laparotomy to resect all suspected segments,thus rebleeding could be avoided.
