This course will provide education through lectures, case discussion, audience question and answer, and hands-on experience with animal models and device simulators. The goal is to highlight best practice techniques across the broad spectrum of therapeutic and biliary endoscopy. Washington University Interventional Endoscopy Section faculty, as well as nationally known therapeutic endoscopists from peer institutions in North America, will serve as faculty with in-room commentary, lectures, hands-on session and facilitating discussion during and between lectures and case presentations.
