Abstract
Bleeding is a lesser-known complication of rectal self-expandable metal stents (SEMS). Most of these bleedings are self-limiting. Life threatening bleeding as a complication of SEMS reported only rarely. In the present paper, we are reporting a rare case of near fatal intraluminal bleeding from rectal SEMS. Traumatic pseudoaneurysm formed in superior rectal branch of the inferior mesenteric artery because of pressure induced by rectal stent. Severe bleeding leads to haemorrhagic shock. Patient was stabilized and angioembolization of pseudoaneurysm with superior rectal branch of inferior mesenteric artery was done. Bleeding stopped post procedure and patient discharged in stable condition. This case presentation highlights the fact that we should decide management strategy for a patient in multidisciplinary meeting and utilize the available resources in best possible ways. Though rectal stents are good alternatives, they have their own set of complications. These should be considered while deciding strategy for the upfront stoma versus rectal stent. For cases as in this article upfront stoma may have avoided the associated complication.
