Self-expandable Metallic Stent for Obstructive Colorectal Cancer in Our Hospital: Evaluation of Short-term Benefit

Abstract

　　Purpose: The self-expandable metallic stent (SEMS) for colorectal obstruction became covered by national health insurance in January 2012, and it has since become a standard treatment. Here we report the utility of SEMS for colorectal obstruction in our department.
　　Patients and Methods: We retrospectively reviewed 65 patients who underwent SEMS placement for colorectal obstruction in our department from May 2013 to December 2018. We examined age, sex, etiology of colorectal stenosis, purpose of stenting, and tumor location.
　　Results: The technical success rate was 98.5% (64/65) and the clinical success rate was 93.8% (61/65). Technical failure occurred in 1 case because the guidewire could not pass the stenosis. Adverse event rates were 1.6% within 7 days and 4.7% after 7 days.
　　Conclusion: SEMS placement had a high technical success rate and few adverse events. Clearly SEMS placement is a minimally invasive procedure that is effective for improving QOL. The safety and effectiveness of this procedure appeared to be excellent.
