The Effect of PPI on Endoscopic Treatment of WON: a Multicenter Randomized Controlled Trial.

In this multicenter, randomized controlled trial, patients with pancreatic walled-off necrosis based on inclusion and exclusion criteria will be randomly assigned in a 1:1 ratio to either receive intravenous infusion or oral administration of continuous proton pump inhibitor or to undergo no PPI (nPPI) therapy after endoscopic ultrasound-guided transluminal drainage/debridement. Clinical data and patient-reported outcomes will be systematically collected at baseline and during follow-up periods. The study aims to assess whether PPI use after EUS-TD (Endoscopic Ultrasonography-Guided Transmural Drainage) increases the number of direct endoscopic necrosectomies required to managing WON. Additionally, the study will investigate the impact of PPI use on the incidence of stent occlusion and postoperative complications following EUS-TD, as well as its effect on the average duration of hospitalization and associated costs for patients with WON.
