Classification, risk factors, and management of lumen apposing metal stent dysfunction during follow‐up of endoscopic ultrasound‐guided choledochoduodenostomy: Multicenter evaluation from the Leuven‐Amsterdam‐Milan Study Group

Abstract

Endoscopic ultrasound-guided choledochoduodenostomy shows excellent initial efficacy and safety, although stent dysfunctions occurs frequently during long-term follow-up. Almost all stent dysfunctions can be managed successfully by endoscopic reinterventions. We propose a comprehensive classification of the different types of dysfunction that may be encountered and rescue procedures that may be employed under these circumstances. Duodenal invasion seems to increase the risk of developing EUS-CDS dysfunction, potentially representing a relative contraindication for this technique.
