Self-expanding metallic stents (SEMS) are a useful palliative option in malignant colorectal obstruction. The aim of this study was to evaluate the clinical outcomes of SEMS used for palliation. Patients with malignant colorectal obstruction who underwent SEMS insertion in our hospital from April 2014 to March 2015 were enrolled in the study. Clinical outcomes and complications of palliative SEMS insertion were retrospectively analyzed. Nine patients were enrolled in the palliative SEMS group. The success rate was 100%, while the complication rate was 11%. Successful SEMS insertion may enable oral intake in a few days, but 3 patients required up to several weeks to resume oral intake. Palliative SEMS are effective and beneficial for malignant colorectal obstruction.
