Description

Objective: The incidence of acute pancreatitis in the elderly patient is increasing, and a significant number of such patients have no clearly defined etiology of their pancreatitis. To delineate the role of early organ failure versus progressive pancreatic disease in the morbidity and mortality, the authors' experience with patients older than 60 years with acute pancreatitis was reviewed. Summary Background Data: As many as 30%-40% of elderly patients with acute pancreatitis have an unclear etiology and such patients have high rates of early organ failure and death. While some authorities have shown that pre-existing disease in these elderly patients did not contribute to subsequent morbidity, others have demonstrated that poor outcome was related to co-existing medical illness. Methods: Their review of acute pancreatitis in the elderly was grouped into known and unknown etiology patients. Various parameters such as morbidity, mortality and length of stay were then compared between the two groups. Severity of organ failure and acute pancreatitis on admission were both graded and attempts made to correlate this severity with subsequent outcome. Results: Unknown etiology patients had a greater number of Ranson's criteria (3.5 ± .44 vs. 2.4 ± .18) (p < 0.02), higher morbidity (48% vs. 22%) (p < 0.05), higher mortality (24% vs. 8.3%), and more SICU days (4.4 ± 1.3 vs. 1.6 ± .44) (p < 0.05) when compared with the known etiology group. Duration of symptoms, admission hypotension, and Ranson's criteria were unsuccessful in predicting mortality. Functional status of the various organ systems on admission did predict subsequent mortality. Conclusions: Elderly patients with acute pancreatitis of unknown etiology present with a more severe disease, have higher morbidity and longer SICU stays, and appear to have greater compromise of organ function. Organ function compromise correlates with mortality and appears more significant than severity of pancreatic disease. Aggressive support of such organ systems may be beneficial in the management of these patients.
