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 drainage and necrosectomy may serve as a minimally invasive alternative in cases in which transgastric or percutaneous drainage is either impossible or fails to secure sufficient drainage. In this paper, we retrospectively evaluated the feasibility, safety, and efficacy of the treatment. We included nine patients and found a technical success rate of 100%, clinical success in 89%, and one adverse event (11%). Transrectal/transcolonic endoscopic necrosectomy was needed in seven patients (78%).
