Core Tip

Core Tip: Scant data are available about rescue techniques in cases of lumen-apposing metal stents (LAMS) misdeployment which is the main cause of technical failure in endoscopic ultrasound-guided drainage procedures. We performed a systematic review of the literature about LAMS misdeployment and rescue techniques in the biliopancreatic setting, focusing on technical aspects and success rate of endoscopic maneuvers. In accordance with our results endoscopic rescue techniques are feasible in most cases (up to 96.8%). Three endoscopic rescue strategies have been identified. The choice of the endoscopic rescue maneuver is based on the clinical scenario, type of misdeployment and expertise of the endoscopic team.
