Randomized Trial of Immediate Endoscopic Necrosectomy vs. Step-up Endoscopic Interventions in Necrotizing Pancreatitis

In the immediate endoscopic necrosectomy group, endoscopic ultrasound-guided drainage of the necrotic collection is performed using a lumen-apposing metal stent, immediately followed by endoscopic necrosectomy. Endoscopic necrosectomy involves removal of infected necrotic pancreatic tissue via the cystogastrostomy/cystoenterostomy tract using a variety of endoscopic accessories.

In the step-up endoscopic interventions group, endoscopic ultrasound-guided drainage of the necrotic collection is performed using a lumen-apposing metal stent. Endoscopic necrosectomy is not performed during the index drainage session, but is performed at a later time as needed.
