Aim Colorectal obstruction due to benign disease is likely to become more prevalent. Self‐expanding stents have been shown to be effective in reducing morbidity and allowing one‐stage resection or improved palliation in colorectal cancer. This review assessed the use of self‐expanding stents in benign colorectal obstruction. Method A systematic review was performed using P ub M ed, E mbase and the C ochrane L ibrary. Keywords included: ‘benign disease’ ‘colorectal obstruction’, ‘stent’, ‘endoprosthesis’ and ‘prosthesis’ Original articles from all relevant listings were sourced. These were hand searched for further articles of relevance. The main outcome measures assessed were technical and clinical success, perforation, reobstruction and stoma avoidance in the bridge to surgery population. Results The search strategy identified 130 articles; the 21 included studies yielded a pooled analysis of 122 patients. Diverticulitis was the predominant aetiology (66/122, 54%). Technical success was achieved in 115/122 (94%) and clinical success in 108/120 (87%) patients. Overall, the perforation rate was 12% (15/122) and the reobstruction rate was 14% (17/122). A stoma was avoided in 48% (23/48) of bridge to surgery patients. Perforation and stoma avoidance in the bridge to surgery group were worse with an aetiology of diverticulitis. Conclusion Complication rates in stenting for benign colorectal obstruction are higher than for malignant obstruction. On the basis of limited published evidence, stenting cannot be recommended for benign colorectal obstruction.
