title: Acute pancreatitis in elderly patients. Pathogenesis and outcome.
abstract: Forty patients over 70 years of age with acute pancreatitis were studied. The most common cause of pancreatitis was biliary tract disease (14 patients, 35 percent). Twelve patients (30 percent) were discharged with a diagnosis of idiopathic pancreatitis, but tests such as endoscopic retrograde cholangiopancreatography that might have established the cause of disease were frequently not employed. Eight of the 40 patients died, for a mortality rate of 20 percent. Significant morbidity occurred in an additional seven (17.5 percent). Multisystem failure was the cause of death in all eight patients, and only two patients with multisystem failure survived. The mortality rate was significantly higher in those patients with postoperative pancreatitis. Acute pancreatitis in the elderly carries a grave prognosis. All patients should undergo thorough evaluation, as biliary tract disease is the most common cause. Cholecystectomy should be performed in those with biliary disease to prevent recurrent attacks.
