Long-Term Follow-up after the First Episode of Acute Alcoholic Pancreatitis: Time Course and Risk Factors for Recurrence

Background: Owing to the current lack of long-term follow-up data on the recurrence of alcohol-induced acute pancreatitis (AP), we studied the pattern of recurrence and determined the characteristics of the disease to predict the recurrence. Methods: Between 1972 and 1991, 2678 AP episodes were detected; 1555 were induced by alcohol, and 591 of them were the first episode. During the first alcohol-induced AP 29 patients died and were excluded from further analysis. Of the 562 included, 503 were men, and 59 women. Admission serum tests, severity index, development of complications, intensive care unit and hospital stay, and need for surgery were assessed. Case records were studied. The national database was used to detect admissions to other hospitals. Results: Overall, 260 (46%) developed recurrent disease. Of the first relapses, 80% developed during 4 years. The recurrence rate has not changed with time. Age less than 45 years increased the risk (odds ratio (OR) = 2.42; 95% confidence interval (CI), 1.30...
