EUS-guided endoscopic necrosectomy and temporary cystogastrostomy for infected pancreatic necrosis with self-expanding metallic stents.

Pancreatic pseudocyst with infected necrotic tissue is associated with necrotizing pancreatitis and carries a high rate of complications and death. Open cystogastrostomy with removal of necrotic material and necrosectomy is the standard treatment for infected pancreatic necrosis but is associated with significant morbidity, mortality, and prolonged hospital stay. Endoscopic cyst drainage with necrosectomy is an alternative and less invasive technique. We report a case of endoscopic ultrasound-guided cystogastrostomy with a fully covered 15-mm-diameter self-expandable metal stent and staged endoscopic necrosectomy through the stent. This is the first case, so far, to use this technique with complete removal of necrotic material without any complications.
