Evaluation of the "Hot Spaxus" Lumen Apposing Stent for EUS-guided drainage of pancreatic walled off necrosis

Acute pancreatitis — inflammation of the pancreas — can sometimes lead to a serious complication called "walled-off necrosis" (WON), where dead tissue becomes encased in a cyst-like fluid collection near the pancreas. This collection can become infected and cause life-threatening illness. The standard treatment is to drain the collection through a stent inserted during an endoscopy (a camera procedure through the mouth). This study is evaluating a recently approved stent called the Hot SPAXUS, used under endoscopic ultrasound guidance to drain these pancreatic fluid collections. While the stent is already available and approved, this Australian study is collecting data on how well it works and how safe it is in real-world clinical practice, which will add to the existing evidence from the USA, Korea, and Europe. Adults aged 18 or older who have symptomatic or infected pancreatic walled-off necrosis confirmed on MRI or CT, are fit for anaesthesia, and are able to provide consent may be eligible. Those who are pregnant, have severe blood-clotting problems, or whose collection does not meet certain criteria on endoscopic ultrasound are excluded. Participation means the collection would be drained with this specific stent as part of your care, with the team collecting follow-up data on your recovery.
