Large-diameter self-expanding metal stents appear to be safe and effective for malignant colonic obstruction with and without concurrent use of chemotherapy

Background Colonic stents are used chiefly for malignant large-bowel obstruction as a palliative measure or bridge to surgery that facilitates one-step resections. Literature on colorectal stenting demonstrates good safety and efficacy; however, a recent trial has raised concerns regarding the safety of a new large-diameter stent, especially in the setting of concurrent chemotherapy. This study evaluated our experience with colorectal stenting using mainly this stent.
