Background: Self-expandable metal stents are a non-surgical option for the treatment of symptomatic malignant colorectal obstruction as palliative treatment or as a bridge to surgery. Aims: To report data from a regional study on self-expandable metal stent (SEMS) placement for malignant colorectal obstruction. Methods: Two hundred and four patients (male 54.9%, mean age of 69.5. ±. 14.2) were retrospectively evaluated and data on technical and clinical success, and complications, were analyzed. Results: Technical and clinical success rates were 99% and 94.6% respectively, with 36.7% treated on an emergency basis and 63.3% electively. Palliative treatment was administered to 70.1%, and as a bridge to surgery for 29.9%. Complications were 17 neoplastic ingrowths, 10 stent migrations, and 4 perforations. Palliative treatment was associated with a higher risk of stent ingrowth (p= 0.003), and chemotherapy with a lower risk of stent ingrowth (p= 0.009). Conclusion: This regional study, although it has certain limitations, confirms the positive role of self-expandable metal stents in the treatment of symptomatic malignant colorectal obstruction, and that chemotherapy decreases the risk of ingrowth.
