How the Experts Do It: Step-by-Step Guide.

Lumen-apposing metal stents are integrated in a single-step delivery system for draining intra-abdominal fluid collections. The theoretic advantage of lumen-apposing stents is the ability to approximate the wall of the drained cavity or organ to the gastrointestinal tract lumen. The use of lumen-apposing stents now includes drainage of organs adjacent to the stomach/duodenum and creation of anastomosis between the stomach and jejunum. The lumen-apposing stents may also serve as a conduit for accessing the remnant stomach for performing biliary tract interventions. This article outlines the approach to placement of lumen-apposing metal stents, technical challenges, and measures to counter adverse events.
