Colonic perforation either during or after stent insertion as a bridge to surgery for malignant colorectal obstruction increases the risk of peritoneal seeding

Background Endoscopic colorectal stenting may be performed as a bridge to surgery in patients with malignant colorectal obstruction, and has been reported to be associated with a high rate of successful primary anastomosis, low rate of stoma formation, and shorter hospital stay. However, the results of recent studies suggest that colorectal stenting could potentially worsen the prognosis. This study aimed to compare outcomes between patients who underwent colorectal stenting as a bridge to surgery and patients who underwent curative surgery only for malignant colorectal obstruction.
