A study of autopsies upon 116 patients with acute pancreatitis

A series of 116 nonselected and consecutive patients with acute pancreatitis with a fatal outcome underwent necropsy and have been analyzed with special attention paid to hepatic findings and the cause of death. This series includes the total fatalities caused by the disease during a 15 year period from 1956 to 1970. All but two patients died in the first attack of acute pancreatitis. The patients were divided into four etiologic groups: gallstone disease, 43 per cent; alcoholism, 25 per cent; idiopathic origin, 18 per cent, and postoperative origin, following abdominal operations, 14 per cent. Over the three five-year periods, the frequency of alcohol abuse as a predisposing factor increased, while gallstone disease showed a corresponding decrease. About 75 per cent of the patients had hyperbilirubinemia. Half of these showed signs of cholestasis. Macroscopic steatosis of the liver was recorded in 62 per cent of the alcohol addicts and in about 25 per cent of the patients in the other etiologic groups. Shock and late sequelae of shock were the dominating immediate causes of death in 72 per cent. About 50 per cent of the fatalities occurred within the first week. Most of these early deaths were caused by intractable circulatory failure. Early death was most commonly caused by alcoholism, followed in frequency by gallstone disease. It is possible that impaired hepatic function contributes to the fatal outcome in both early and late phases of the disease.
