Immediate vs. On-demand Endoscopic Necrosectomy in Infected Walled-off Pancreatic Necrosis

Iran50 participantsStarted 2022-09-12

Plain-language summary

Acute pancreatitis is one of the most common diagnoses made in gastroenterology wards worldwide which causes a great deal of pain and expense along with fatal complications. Approximately, 10-20% of patients progress to necrotizing pancreatitis that result in significant morbidity and mortality. Initial conservative management may be feasible in necrotizing pancreatitis, however the majority of patients with infected necrosis or persistent symptoms will eventually require a drainage procedure. Drainage procedures for necrotizing pancreatitis include open surgery, minimally invasive surgery, percutaneous drainage, and endoscopic drainage. In the recent years, minimally invasive approaches have largely replaced open surgical necrosectomy. Endoscopic drainage of walled off pancreatic necrosis involves creation of a transmural fistula between the enteral lumen and WOPN cavity with stent placement under endoscopic ultrasound (EUS) guidance. Furthermore, direct endoscopic necrosectomy can be performed through the fistula track. The best timing for endoscopic necrosectomy is not yet defined. A recent retrospective study suggested that immediate necrosectomy after stent placement results in earlier resolution of WOPN with fewer sessions of endoscopic necrosectomy. The aim of this study is to compare immediate vs. on-demand endoscopic necrosectomy in patients with infected WOPN who undergo EUS-guided transmural drainage of WOPN.

Inclusion Criteria: * Documented history of acute pancreatitis * Necrotic collection with partial or complete wall diagnosed on CT or MRI * Necrotic collection of any size with any number of loculations with more than 20% of solid/necrotic component * Necrotic collection is accessible and amenable for EUS-guided drainage * Age \>= 18 years * Suspected or confirmed infection in the necrotic collection * The patient understands and accepts to sign the informed consent. Exclusion Criteria: * Irreversible coagulopathy with INR\>1.5 or platelet counts \<50,000 * Necrotic collection is not accessible for EUS-guided drainage * Females who are pregnant * Previous intervention (e,g, percutaneous drainage, or surgery) is performed for the patient

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
