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.",[83],"Pancreatic Walled-off Necrosis",[83,85,86,87,88],"Direct Endoscopic Necrosectomy","Proton Pump Inhibitor","Randomized Controlled Trial","Endoscopic Ultrasound-guided Transluminal Drainage\u002FDebridement","2026-08-06",{"date":91,"type":92},"2026-08-10","ACTUAL",{"date":94,"type":92},"2025-09-17",{"date":96,"type":77},"2028-03-20",{"name":5,"class":6},1]
