An international, multicenter, comparative trial of EUS-guided gastrogastrostomy-assisted ERCP versus enteroscopy-assisted ERCP in patients with Roux-en-Y gastric bypass anatomy

ERCP is challenging in patients with Roux-en-Y gastric bypass (RYGB) anatomy. EUS-guided gastrogastrostomy (GG) creation is a promising novel technique to access the excluded stomach in order to facilitate conventional ERCP. We aimed to compare procedural outcomes and adverse events (AEs) between EUS-guided gastrogastrostomy-assisted ERCP (EUS-GG-ERCP) and enteroscopy assisted ERCP (e-ERCP) in patients with RYGB.
