Abstract
EUS-guided gallbladder drainage (EUS-GBD) is gradually emerging as an option for patients with cholecystitis. A stent-bridged endoscopic intervention in the gallbladder (GB) has been proposed. The formation of a fistulous tract after EUS-GBD facilitates the entry of the endoscope inside the GB to perform endoscopic lithotomy and polypectomy, which is an efficient and safe procedure. However, the technical aspects of this procedure in order to optimize the success rate have only been scarcely discussed. This paper discusses the EUS-GBD prepared for per-oral cholecystolithotomy, the stent indwelling time, the procedure, the devices of per-oral cholecystolithotomy and the follow-up. The recently published literature on this topic is also updated in this review.
