<unk>  is a late complication of acute necrotizing pancreatitis, occurring more than 4 weeks after the initial attack. A<unk>  is a collection of pus resulting from tissue necrosis, liquefaction, and infection. It is estimated that approximately 3% of the patients suffering from acute pancreatitis will develop an<unk> . According to the Balthazar and Ranson's radiographic staging criteria, patients with a normal pancreas, an enlargement that is focal or diffuse, mild peripancreatic inflammations or a single collection of fluid (pseudocyst) have less than 2% chances of developing an<unk> . However, the probability of developing an<unk>  increases to nearly 60% in patients with more than two pseudocysts and gas within the pancreas.
