Outcomes of Interval Cholecystectomy Following Endoscopic Ultrasound-guided Gallbladder Drainage: A Systematic Review and Meta-Analysis.

Background And Aims: Cholecystectomy (CCY) is considered the gold standard intervention for acute cholecystitis (AC). However, endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) can be performed in patients unfit for surgery. Interval CCY after EUS-GBD is typically not performed as the formation of cholecystoenteric fistula increases the technical complexity of CCY.
