Purpose Malignant bowel obstruction is a common presentation and is associated with high morbidity and mortality. Emergency resection is the traditional treatment modality. In recent years, colonic stenting as a bridge to surgery has become more prevalent. However, there is considerable debate surrounding its use. The aim of this review was to examine the technical and clinical success of self-expanding metal stent (SEMS) as a bridge to surgery for obstructing colorectal tumours. Methods We systematically reviewed randomised controlled trials using PubMed, Cochrane and SCOPUS databases. Included studies must have compared outcomes in SEMS as a bridge to surgery with those proceeding straight to emergency resection. Results A total of 1245 studies were identified. After removal of duplicates and non-relevant studies, we identified seven articles which met the predefined criteria. This review observed that 81% of SEMS were technically successful, with 76% of patients having restoration of gastrointestinal function. Iatrogenic perforation rate was 5%. One-fifth of patients required emergency surgery following stent placement, and permanent stoma rate was 8.7%. Conclusion This study observed that SEMS as a bridge to surgery is associated with good technical and clinical success, with low rates of perforation and permanent stoma. SEMS should be part of the treatment armamentarium for obstructing colorectal neoplasms, but careful patient selection and institutional expertise are important factors for success.
