OBJECTIVE To provide evidence-based guidelines regarding the appropriate use of gastrointestinal stents for oncologic indications. This document describes the use of gastrointestinal stents by appropriately trained physicians. METHODS This document is based on a review of the published evidence and supplemented by consensus expert opinion. Gastrointestinal stenting has been evaluated in terms of technical success, complications, patient satisfaction, clinical outcome, and cost-benefit analysis. This document was approved by the Canadian Interventional Radiology Association; approval from the other relevant Canadian societies is pending. CONCLUSION Gastrointestinal stenting has a valuable role in the management of gastrointestinal malignancy. The decision to use such devices should be taken after comprehensive multidisciplinary clinical, endoscopic, and radiologic evaluation.
