Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) is increasingly utilised for patients with acute cholecystitis who are high-risk candidates for surgery. The technique to perform EUS-GBD has evolved and matured over the last two decades since EUS-GBD was first described in 2007 using a nasobiliary catheter. Compared to percutaneous gallbladder drainage (PT-GBD), EUS-GBD offers benefits of shorter hospitalisation stay and lesser procedural pain and need for reintervention. The purpose of this review is to provide an updated review of the equipment and techniques available for EUS-GBD, outcomes of the procedure and how it compares against endoscopic transpapillary drainage (ET-GBD), PT-GBD and laparoscopic cholecystectomy. Controversies surrounding the procedure will also be discussed.
