Does giving PPIs after endoscopic draining of pancreatic walled-off necrosis change how treatment proceeds?
Official title: The Effect of Proton Pump Inhibitors on Endoscopic Treatment of Walled-off Necrosis: a Multicenter Randomized Controlled Trial
Run by Qilu Hospital of Shandong University · NCT07488299 · Data updated 2026-11-12
This trial tests whether continuing proton pump inhibitors after an endoscopic procedure for pancreatic walled-off necrosis helps or hinders treatment, compared with not using PPIs.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–80 with confirmed pancreatic walled-off necrosis requiring EUS-guided transluminal drainage/debridement.
✕Probably not a fit
Patients with certain coexisting conditions or contraindications to PPI therapy may not benefit, and some may experience no difference or potential adverse effects from PPIs.

What this trial studies
This multicenter, randomized study enrolls adults with pancreatic walled-off necrosis who need endoscopic drainage/debridement. Participants are randomly assigned to receive IV or oral PPIs, or no PPI therapy after the procedure, to see how PPIs affect the number of direct endoscopic necrosectomies, stent occlusion, and postoperative complications. Researchers will collect baseline data and follow-up outcomes, including hospital stay length and costs. The goal is to determine if PPI use after EUS-guided drainage influences clinical course and resource use.
Why it matters
Potential benefit: If PPIs after endoscopic treatment prove beneficial or safe, patients may experience shorter or more predictable hospital stays and fewer procedure-related complications.
How similar studies have gone: Earlier work in similar endoscopic approaches has yielded mixed results; this trial explores a novel aspect by testing post-procedure PPI use specifically.

Inclusion Criteria: 1. Patients aged 18 years or older and not exceeding 80 years of age. 2. Patients with a confirmed diagnosis of WON. 3. Patients requiring endoscopic ultrasound-guided transluminal drainage/debridement therapy. 4. Patients who have signed informed consent forms. Exclusion Criteria: 1. Patients diagnosed with chronic pancreatitis who have not experienced an acute pancreatitis attack within the past three months. 2. Patients with severe coagulation disorders (International Normalized Ratio \[INR\] \> 1.5). 3. Patients with significant thrombocytopenia (platelet count \< 50 × 10\^9/L). 4. Pregnant women. 5. Patients undergoing endoscopic drainage solely through the duodenum. 6. Patients with a history of gastrectomy, gastric bypass surgery, or prior surgery for pancreatic-related diseases. 7. Patients currently taking medications that may affect gastric acid secretion or metabolism, such as strong cytochrome P450 (CYP) 3A4 inhibitors (e.g., clarithromycin, itraconazole) or inducers (e.g., rifampin, carbamazepine). 8. Patients requiring long-term use of acid-suppressing medications such as PPIs and P-CABs due to other medical conditions. 9. Patients with a history of acid-suppressive medication use (e.g., PPI) and a washout period of less than 14 days. 10. Patients with documented contraindications to PPIs or a relevant history of hypersensitivity.
