<unk>  is an unusual and rare, but life threatening complication of acute pancreatitis. It develop 5 weeks after the onset of pancreatitis and after onset of symptoms and subsidence of the acute phase of pancreatitis. Most of the<unk> es are developed from the progressive liquefaction of necrotic pancreatic and peri-pancreatic tissues, but some arise from infection of peri-pancreatic fluid or collections elsewhere in the peritoneal cavity. According to the Balthazar and Ranson's radiographic staging criteria, patients with a normal pancreas, an enlargement that is focal or diffuse, mild peri-pancreatic inflammations or a single collection of fluid (pseudocyst), have less than 2% chances of developing an abscess. However, the probability of developing an abscess increases to nearly 60% in patients with more than two pseudocysts and gas within the pancreas.<unk>  is the most dangerous complication and the most common cause of death for acute pancreatitis.
