Plain-language summary

Goal: The goal of this clinical trial is to compare the effectiveness and safety of two different but highly effective treatment approaches for walled-off necrosis (WON) resulting from severe acute pancreatitis. Participant Population: The study will involve adult patients experiencing symptomatic WON due to acute necrotizing pancreatitis. Main Questions: The main questions it aims to answer are: 1. Is "endoscopy" or direct endoscopic necrosectomy (DEN) with powered endoscopic debridement (PED) as effective as "surgery" or transgastric surgical necrosectomy (SN) in achieving clinical resolution of WON within six weeks after treatment? 2. What are the rates of complications, costs, hospital length of stay, procedure time, readmission, repeat procedures and overall patient satisfaction associated with DEN with PED compared to transgastric SN? Comparison Group: Researchers will compare the outcomes of patients receiving DEN with PED to those undergoing transgastric SN to see if there are significant differences in clinical success, rates of complications, and overall healthcare costs. Participants Will: 1. Be randomly assigned to one of the two treatment groups (DEN with PED or transgastric SN). 2. Undergo the assigned treatment procedure based on their group. 3. Complete assessments before and after the procedure to evaluate clinical outcomes, hospital stay length, quality of life, and patient satisfaction. 4. Be monitored for adverse events or complications following the treatment

Inclusion Criteria: * Patients 18 years of age or greater. * Patients with first episode of symptomatic WON+ due to acute pancreatitis (+Persistent fatigue, malaise, abdominal pain, gastric outlet obstruction, early satiety, fever, chills, jaundice, reduced appetite, persistent nausea/vomiting, steatorrhea) * Patients who are candidates for surgical or endoscopic necrosectomy of WON as deemed by a multidisciplinary committee of HPB surgeons and therapeutic endoscopists. * Patients who can tolerate repeat procedures. * Subjects with the ability to understand the requirements of the study, who have provided written informed consent, and who are willing and able to return for the required follow-up assessments. Exclusion Criteria: * Documented untreated pseudoaneurysm within WON. * Subject unable or unwilling to provide informed consent. * Intervening gastric varices or unavoidable blood vessels within the WON access tract (visible using pre-procedural imaging). * Coagulation disorders or anti-coagulant therapy which cannot be discontinued for the intervention to an absolute cardiac or vascular indication such as ACS, Stroke, Mechanical cardiovascular valves. * Pregnant or lactating women or women of childbearing potential who do not employ a reliable method of contraception as judged by the Investigator, and/or are not willing to use reliable contraception for the duration of study participation. * Patient is enrolled in another trial that could interfere with the endpoint a…
