ACUTE PANCREATITIS

Abstract
This study is based on all the available records of patients with acute pancreatitis who were treated by members of the Chicago Surgical Society.1 The following classification has been found satisfactory: A. Acute idiopathic pancreatitis 1. Simple edematous or nonhemorrhagic pancreatitis 2. Hemorrhagic pancreatitis 3. Necrotic or gangrenous pancreatitis 4. Suppurative pancreatitis B. Acute pancreatitis associated with malignancy C. Acute pancreatitis following trauma Fitz2 classified acute pancreatitis into hemorrhagic, suppurative and gangrenous. Brocq3 classified it as aseptic and infected. He included four degrees of aseptic pancreatitis: acute hemorrhagic, edematous, subacute encysted and attenuated. Brocq considered gangrenous pancreatitis as infected with anaerobic, and the suppurative type as infected with pyogenic, bacteria. In 1856, Bernard4 reported the production of an acute hemorrhagic pancreatitis following the experimental injection of bile and sweet oil into the pancreatic duct, with death after eighteen hours. Many other substances produced similar results. Considerable
