EUS-guided transcolonic drainage and necrosectomy in walled-off necrosis: a retrospective, single-center case series

Abstract Background and study aims Transgastric endoscopic ultrasound (EUS)-guided drainage and, if needed, necrosectomy is the preferred treatment in patients with pancreatic walled-off necrosis. EUS-guided transcolonic or transrectal may serve as a minimally invasive alternative cases which transgastric percutaneous either impossible fails to secure sufficient drainage. In this paper, we retrospectively evaluated feasibility, safety, efficacy of treatment. We included nine found technical success rate 100%, clinical 89%, one adverse event (11%). Transrectal/transcolonic was needed seven (78%).
