Outcome Measures
Primary Outcomes (1)
The number of interventions performed between metal and plastic stent groups to achieve treatment success
The primary objective of this study is to compare the number of interventions performed between metal and plastic stent groups to achieve treatment success at 6 week follow-up. Re-intervention is defined as the need for repeat EUS-guided drainage of WON using the same stent type and/or DEN and/or insertion of percutaneous catheter due to inadequate treatment response following initial WON drainage. As FCSEMS have larger diameter than plastic stents, the investigators hypothesize that the no. of re-interventions performed will be lower in the FCSEMS group compared to the plastic stent group.

Study Arms (2)
FCSEM Stent
ACTIVE COMPARATORWON is first identified using EUS and punctured using a 19 gauge needle. 10 ml of fluid is aspirated and sent for gram stain and culture with sensitivities. Using a catheter-based stent delivery system with a 15mm AXIOS stent mounted onto it is inserted into the echoendoscope, and introduced into the WON cavity so that the stent lies within both the WON and enteric lumen. The stent is then deployed so that one flange of the stent is located within the WON cavity and the other flange is located within the enteric lumen.
Plastic Stents
ACTIVE COMPARATORWON is first identified using EUS, and punctured using a 19 gauge needle. 10 ml of the WON fluid is aspirated and sent for gram stain and culture with sensitivities. A 0.025 or 0.035 inch guidewire is inserted into the WON through the fine needle aspiration (FNA) needle. A transmural tract is created using an Endoscopic Retrograde Cholangiopancreatography(ERCP) catheter (with the use of a needle knife catheter ± cautery if needed), and then dilated using a 12-13.5-15mm Controlled Radial Expansion (CRE) balloon to a maximum size of 15mm if technically possible. Two or three 7 French plastic stents are inserted through the transmural tract into the WON cavity.

Eligibility Criteria
You may qualify if:
- The subject (or when applicable the subject's LAR) is capable of understanding and complying with protocol requirements.
- The subject (or when applicable the subject's LAR) is able to understand and willing to sign an informed consent form prior to the initiation of any study procedures.
- Males or females ≥ 18 years of age.
- WON diagnosed on contrast-enhanced dual phase CT abdomen/pelvis (CECT) or MRI with gadolinium (seen as a fluid collection in the setting of documented pancreatic necrosis that contains necrotic material and encased within a well-defined tissue layer).
- WON of any size with any quantity of solid/necrotic component and any no. of loculations, located within the pancreatic/peri-pancreatic space not requiring percutaneous drainage, within 2cm of the enteric wall
- Suspected/confirmed infected WON (defined as temp ≥ 100.5°F, serum White Blood Cells ≥ 15x109/L, positive blood cultures or positive Gram stain/culture of aspirated necrotic material), and/or symptomatic WON (defined as abdominal pain, gastric/intestinal/biliary outlet obstruction resulting in nausea, vomiting, early satiety, jaundice, or persistent malaise) ≥ 4 weeks from attack of acute pancreatitis.
- Documented history of acute or chronic pancreatitis:
- i. Acute pancreatitis is diagnosed if 2 of the following 3 criteria are met:
- Abdominal pain characteristic of acute pancreatitis
- Serum lipase/amylase ≥ x3 upper limit of normal
- Characteristic radiological findings of acute pancreatitis on CECT/MRI/US abdomen, such as homogeneous enhancement of pancreatic parenchyma, standing of peripancreatic fat ii. Chronic pancreatitis is diagnosed if characteristic radiological changes are seen on CT/MRI with Magnetic resonance cholangiopancreatography (MRCP) (such as pancreatic atrophy, dilated pancreatic duct, pancreatic calcification) or EUS (≥5/9 of Rosement criteria)
- Able to undergo general anesthesia
You may not qualify if:
- Females who are pregnant or lactating. Pregnancy for females of childbearing potential will be determined by routine preoperative urine or serum Human Chorionic Gonadotropin testing.
- Irreversible coagulopathy (INR \>1.5, thrombocytopenia with platelet count \<50,000/mL)
- Has surgically altered gastrointestinal anatomy such as but not limited to Billroth II, Roux-en-Y, gastric bypass
- Age \< 18 years
- Unable to obtain consent for the procedure from either the patient or LAR
- Use of anticoagulants that cannot be discontinued for the procedure
- Unable to tolerate general anesthesia
- WON that is not accessible for EUS-guided drainage
- Percutaneous drainage of WON is required or performed prior to EUS-guided drainage
