Percutaneous Debridement of an Infected Pancreatic Walled-off-Necrosis (WON) with a Flexible Bronchoscopic Cryoprobe

Purpose: Over the past years US- or EUS-guided catheter drainage and necrosectomy have become gold-standard in the treatment of necrotizing pancreatitis. The transgastral approach allows for direct inspection of the necrotic cavity using a standard gastroscope after dilatation of the transgastral access. Various endoscopic devices can be inserted in order to remove necrotic tissue. For minimally-invasive percutaneous treatment, however, therapeutic options are limited to insertion of drains with subsequent irrigation since the access cannot be dilated as much as in the transgastral approach. If percutaneous necr…
