Endoscopic ultrasound in the management of acute cholecystitis. a practical review.

Abstract

Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has emerged over the last years as an alternative procedure to percutaneous drainage (PT)-GBD in patients with acute cholecystitis (AC) at high surgical risk. This process has been driven by the advent of lumen-apposing metal stents (LAMSs) with electrocautery-enhanced capability, which has rendered the drainage procedure easier to accomplish and safer. Studies and meta-analyses have proven the superiority of EUS-GBD over PT-GBD in high-surgical-risk patients with AC. Little evidence also exists in the same setting that EUS-GBD compares equally with laparoscopic cholecystectomy (LC). Moreover, EUS-GBD might theoretically have a possible role in patients at high surgical risk with an indication to undergo cholecystectomy or with a high probability of conversion from LC to open cholecystectomy. Properly designed studies are needed to better clarify the role of EUS-GBD in these patient populations.
