Is endoscopic necrosectomy the way to go?

Abstract

Pancreatic necrosis with the formation of walled-off collections is a known complication of severe acute pancreatitis. Infected necrotic pancreatic collections are associated with a high mortality rate. Open necrosectomy and debridement with closed drainage has traditionally been the gold standard for treatment of infected pancreatic necrosis, but carries a high risk of perioperative complications. Direct endoscopic necrosectomy has emerged as a safe and effective modality of treatment for this condition. Careful patient selection and gentle meticulous debridement is important to optimize clinical success. Bleeding is the commonest associated complication with the procedure but most cases can be managed conservatively. Air embolism, although rare, is potentially fatal. The use of fully covered large diameter lumen apposing self-expandable metal stents has further simplified the procedure. These stents optimize drainage, and facilitate endoscopic necrosectomy because repeat insertion of the endoscope into the necrotic cavity can be easily achieved.
