Purpose. To assess the safety and efficacy of self-expanding metallic stent (SEMS) placement in the treatment of malignant colorectal obstruction. Methods. A retrospective chart review of 49 patients undergoing SEMS placement for conservative treatment between April 2013 and December 2016 at Changhua Christian Hospital was conducted. Results. Atotal of 49 patients received stents as conservative treatment. The technical and clinical success rates were 94% and 90%, respectively. Early major complications (8%) related to stent placement included perforation (2/49) and stent migration (2/49). Late complications (18%) were migration (3/49), re-obstruction (4/49), death (1/49), and bleeding (1/49). Conclusions. SEMS placement is an effective and safe conservative treatment for malignant colorectal obstruction.
