Extended Open Transgastric Necrosectomy (EOTN) as a Safer Procedure for Necrotizing Pancreatitis.

The treatment of infected necrotizing pancreatitis has evolved from time to time and the success of surgical intervention depends on the timing of necrosectomy. Bacterial infection occurs in 40-70% of patients with necrotizing pancreatitis. Infection is the main risk factor for mortality among patients with pancreatic necrosis. Timely intervention is generally required for pancreatic necrosis but is now deferred until four weeks after disease onset in order to permit encapsulation and demarcation of the necrotic material. Demarcation facilitates necrosectomy and reduces complications related to the drainage and debridement procedures. The approach to pancreatic necrosectomy has evolved from primary open necrosectomy to minimally-invasive radiologic, surgical and endoscopic procedures. Direct endoscopic necrosectomy is a minimally-invasive technique that was introduced in recent years for the treatment of walled-off necrosis. The pancreas is approached through the posterior wall of stomach and debridement is done.
