We compared the clinical efficacy and safety of endoscopic stenting in malignant colorectal obstruction between elderly patients over 75 years old and younger patients. From April 2017 to November 2021, 61 patients with malignant colorectal obstruction were performed stenting procedures to relieve the obstruction. Uncovered self-expanding metal stents (SEMS) were placed endoscopically under fluoroscopic guidance in all patients. Stent placement was technically successful in 61/61 (100%). Bridge to surgery (BTS) /best supportive care (BSC) (16/19 vs 19/7, p=0.04), CROSS Score (before placing SEMS) (1.7 vs 1.8, p=0.64), CROSS Score (after placing SEMS) (4.0 vs 4.0, p=1.0), time to recommencing food intake (2.9±1.7 vs 2.7±1.3 days, p=0.63), and hospital stay (18±12 vs 14±9 days, p=0.20) were not significantly different between the two groups, while other complications were not significantly different between the two groups. There were no significant differences between the elderly and young groups with respect to overall survival (522 vs 1416 days, p=0.66). Stent placement for colorectal obstruction is an effective and relatively safe procedure for elderly people over 75 years old.
