Use of the Bard Memotherm self-expanding metal stent in the palliation of colonic obstruction

Background: Self-expanding metal stents (SEMS) are a recognized means of palliating large bowel obstruction due to colonic neoplasia. The literature mainly relates to the use of modified esophageal stents (expanded diameter, 18–22 mm) in the colorectum. Stent migration has been a common complication and may be related to expanded stent diameter. This series reports our experience with the Memotherm Colorectal SEMS (expanded diameter, 25–30 mm).
