[Edematous form of acute pancreatitis]

Among a numerous contingent of patients with acute edematous peritonitis a group of 135 subjects with a pure form of acute edematous peritonitis was singled out. A sharp differentiation between proper acute pancreatitis and associated one and the fact, that these patients are singled out as a separate group are of certain clinical importance. Proper acute pancreatitis is characterized by primary affection of pancreatic vessels but not by the mechanic obstruction of the ducts.
