The purpose of this study was to extend the application self-expandable metallic stents by investigating their usefulness in treating colorectal obstructions caused unresectable extrinsic tumors.From January 2000 November 2005, a total 60 stenting procedures were performed, and 57 deployed 39 patients with tumors. success rate complications analyzed retrospectively.The most common etiology location obstruction advanced gastric cancer transverse colon. Technical 34 (87.2 percent). causes technical failure immediate stent migration (n = 1), problems access because bowel immobilization 3). Clinical 32 successes (82.1 two without clinical had multifocal strictures bowel. Complications occurred 22 (38.6 percent), including reobstruction 14) 5). All migrations except one developed covered stents.In colonic tumors, insertion provided effective symptom relief can be reasonable alternative choice colostomy. An uncovered might more preferable, considering less remaining short life expectancy, compared stent.
