She was repeatedly trans...

Background and study aims  Self-expandable metallic stents (SEMS) have been widely used for left-sided colorectal obstruction. Few studies on SEMS placement for right-sided colonic obstructions have been reported because stenting in the right colon is technically difficult, particularly in the ileocecal region. We present 4 cases of successful bridge-to-surgery stenting for ileocecal cancer. Us...
