Clinical Use of the 20mm AXIOS™ Stent and Electrocautery Enhanced Delivery System to Drain Walled-off Pancreatic Necrosis By Douglas Adler, M.D., University of Utah School of Medicine, Huntsman Cancer Center, Salt Lake City, Utah, U.S.A.
A 33-year-old man developed severe acute necrotizing pancreatitis of unclear etiology. The patient developed a large pancreatic fluid collection (PFC) largely replacing the body and tail of the gland. Biliary obstruction due to compression of the bile duct by the PFC was addressed by ERCP with plastic stent placement. Over 6 weeks, the patient’s PFC was seen to mature with good apposition to the posterior wall of the stomach. The patient was referred for EUS and transluminal stent placement/cystgastrostomy.
The AXIOS Stent and Delivery System and the AXIOS Electrocautery Enhanced Stent and Delivery System Indications for Use:
U.S.: The AXIOS Stent and Delivery System and the AXIOS Electrocautery Enhanced Stent and Delivery System is indicated for use to facilitate transgastric or transduodenal endoscopic drainage of symptomatic pancreatic pseudocysts > 6cm in size and walled-off necrosis > 6cm in size with > 70% fluid content that are adherent to the gastric or bowel wall. Once placed, the AXIOS Stent functions as an access port allowing passage of standard and therapeutic endoscopes to facilitate debridement, irrigation and cystoscopy. The stent is intended for implantation up to 60 days and should be removed upon confirmation of pseudocyst or walled-off necrosis resolution.
Europe: The HOT AXIOS Stent and Electrocautery Enhanced Delivery System & the AXIOS Stent and Delivery System are indicated for use to facilitate transgastric or transduodenal endoscopic drainage of a pancreatic pseudocyst or a walled-off necrosis with > 70% fluid content or the biliary tract.
