AIM: To assess the safety and efficacy of self-expandable metal stents(SEMSs) for malignant colorectal obstruction. METHODS: Data regarding technical success, clinical success, and procedure related complications were collected from included studies. Der Simonian-Laird random effects model was used to generate the overall outcome. Thirty international studies with a total of 2058 patients with malignant colorectal obstruction were included. RESULTS: The technical and clinical success rates for SEMS placement were 94%(95%CI: 92-96) and 91%(95%CI: 88-93), respectively. Overall complication rate for SEMS was 23%(95%CI: 18-29). Stent migration8%(95%CI: 6-10) and stent obstruction 8%(95%CI: 6-11) were the most common complications, followed by perforation 5%(95%CI: 4%-7%). Surgical or endoscopic re-interventions were needed in 14%(95%CI: 10-18) of patients. Endoscopic repeat stent placement was required in 8%(95%CI: 6-10), while surgical intervention was needed in 6%(95%CI: 4-8).CONCLUSION: SEMS are effective when used as palliation or bridge to surgery for malignant colorectal obstruction with high technical and clinical success. About 14% of patients require repeat endoscopic or surgical intervention for stent failure or to manage stent related complications.
