Table 1 Classification of pancreatic fluid collections
TermDefinition
Acute fluid collectionA collection of enzyme-rich pancreatic juice occurring early (within 48 h) in the course of acute pancreatitis, located in or near the pancreas and always lacking a well-defined wall of granulation tissue or fibrous tissue
Acute pseudocystA collection of pancreatic juice enclosed by a wall of nonepithelialized granulation tissue, arising as a consequence of acute pancreatitis, requiring at least 4 wk to form and devoid of significant solid debris
Chronic pseudocystA collection of pancreatic juice enclosed by a wall of fibrous or granulation tissue, arising as a consequence of chronic pancreatitis
Early pancreatic necrosisA diffuse or focal area of nonviable pancreatic parenchyma greater than 30% of the gland by CT-scan, typically associated with peripancreatic fat necrosis
Late organized pancreatic necrosisEvolution of acute necrosis to a partially encapsulated, well-defined collection of pancreatic juice and necrotic debris
Pancreatic abscessA circumscribed intra-abdominal collection of pus, usually in proximity to the pancreas, containing little or no pancreatic necrosis, arising as a consequence of acute pancreatitis or pancreatic trauma
