Background: Pancreatic pseudocyst and walled-off pancreatic necrosis/WOPN/associated with acute pancreatitis have been managed with success using nonoperative techniques. Methods: The last two years 11 patients (pts) underwent transmural/trans-duodenal or trans-gastric/endoscopic drainage/lavage of sterile (2 pts, 18%) and infected (9 pts, 82%) WOPN.
