Abstract:
Placement of self-expandable metal stents (SEMS) is an effective mode of palliative treatment for patients with malignant gastrointestinal obstruction. Gastrointestinal mucosal bleeding complicates about 5% of placement of SEMS but is not well described. We report three cases of gastrointestinal bleeding post-SEMS placement and suggest that bleeding is caused by direct mucosal infringement by the sharp edges of the ends of the stents.
