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:
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:

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Direct Endoscopic Necrosectomy | Experimental | Subjects randomized to the endoscopy arm will undergo direct endoscopic necrosectomy using the Powered Endoscopic Debridement System which has CE-Mark 613797 and FDA De Novo clearance in the United States (DEN200016). |
|
| Transgastric Surgical Necrosectomy | Experimental | Patients randomized to the surgical arm will undergo open or minimally invasive (laparoscopic) transgastric surgical necrosectomy (SN). In either approach, the peritoneal cavity is entered to identify the stomach through which an anterior gastrotomy is made. The retrogastric necrosum is identified either using a finder needle or ultrasound and accessed through a posterior cystgastrostomy. Transgastric SN is then manually performed, and any cyst fluid fully evacuated. The anterior gastrotomy is then closed allowing any residual necrosis or pancreatic enzyme to efflux into the stomach and enter the upper GI tract. As with endoscopy, patients with retrogastric collections are observed for a sufficient period to ensure full maturation of the necrosum. |

| Transgastric Surgical Necrosectomy | Procedure | Patients randomized to the surgical arm will undergo open or minimally invasive (laparoscopic) transgastric SN with the aim of creating an ample size cystgastrostomy to perform a complete debridement. In either approach, the peritoneal cavity is entered to identify the stomach through which an anterior gastrotomy is made. The retrogastric necrosum is identified either using a finder needle or ultrasound and accessed through a posterior cystgastrostomy. Transgastric SN is then manually performed, and any cyst fluid fully evacuated. The anterior gastrotomy is then closed allowing any residual necrosis or pancreatic enzyme to efflux into the stomach and enter the upper GI tract. As with endoscopy, patients with retrogastric collections are observed for a sufficient period to ensure full maturation of the necrosum. |
|
| Clinical improvement within 72 hours of debridement | Clinical improvement is defined according to the criteria used in the PANTER and TENSION trial. (8-10) "Clinical improvement" defined as: i. Improved function of at least two organ systems (i.e. circulatory, pulmonary, renal) according to the Investigator's medical judgement within 72 hours of the procedure, or; ii. At least 10% improvement of two out of three parameters of infection (i.e. C-reactive protein, leucocyte count or temperature) within 72 hours of the procedure. Deterioration of these parameters by other infectious causes (e.g.urinary tract infection) will be excluded. | From initial intervention to 72 hours after treatment |

| Overall cost of care at 6 weeks | Cost of care per patient to achieve overall primary outcome | From initial intervention to followup at 6 weeks |
| Percent reduction in WON collection volume (cm3) at 6-month follow-up | Percent reduction in overall size of the WON collection volume (cm3) compared to pre-treatment CT or MR imaging. | From initial intervention to the end of followup at 6 months |
| Percent resolution of solid necrosum in patients with pre-and post-MR imaging at 6-month follow up | Percent reduction in solid necrosis component of the WON collection volume (cm3) compared to pre-treatment MRI scan. | From initial intervention to the end of followup at 6 months |

| Requirement of percutaneous drain | Need for additional drainage with percutaneous drain | From initial intervention to the end of followup at 6 months |
| Total anesthesia duration | Total duration of anesthesia of primary intervention | On day of intervention (1 day) |
| Procedure-related adverse events | Any adverse event resulting from endoscopic intervention (yes/no) | From initial intervention to the end of followup at 6 months |
| Disease-related adverse events | Any adverse event resulting from necrotizing pancreatitis | From initial intervention to the end of followup at 6 months |
| Patient satisfaction | Patient satisfaction of primary intervention at 6 weeks post intervention graded on a visual analog scale (0-10) | From initial intervention to the end of followup at 6 months |
| Subject quality of life (QOL) | Quality of life survey to participants at 6 month follow up. Patients will be asked to place a mark on a horizontal 10 cm line indicating his/her QoL from very poor to very good. The wording will be: "How would you rate your overall quality of life?". Higher score indicates very good quality of life and lower score indicates poor quality of life. The instrument is valid and has been used in clinical trials. | From initial intervention to the end of followup at 6 months |
