Objective: A great number of studies have been published on acute pancreatitis, but few have focused on the recurrent form. In this study, we have sought to determine the relative frequency and mortality of recurrent acute pancreatitis, and also to update our knowledge of its etiological factors., Methods: Patients were selected from a total of 1068 persons included in a previous European study of acute pancreatitis. All were admitted to a hospital with an attack of acute pancreatitis between January, 1990 and December, 1994. Data for each patient was recorded on a standardized form., Results: Of the 1068 with acute pancreatitis, 288 (27%) had recurrent pancreatitis; the majority (78.8%) were men, with a mean age of 43 yr (range 16-95 yr). Regarding etiology, alcohol was the most frequent factor (57%), followed by gallstones (25%), other factors (7.6%), and no identified factor (10.4%). Of the 288 patients, 17 (5.9%) died, all of whom had necrotizing pancreatitis; among all of the patients with necrotizing pancreatitis (141 of 288), the mortality was 12.1%. These percentages are lower than those for patients who had a single attack (8.5% and 18.6%, respectively), but not to a statistically significant degree. Mortality was significantly lower among patients with alcoholic pancreatitis (6.9%) than among those with biliary (30%) (p < 0.002) or idiopathic pancreatitis (25%) (p < 0.04). Most of the deaths (82.4%) occurred at the second attack of pancreatitis., Conclusion: Acute recurrent pancreatitis remains a frequent disease, with alcohol being the most frequent etiological factor. Mortality is similar to that of a single episode of acute pancreatitis, and it is significantly lower among patients with alcohol as the etiology.

Introduction: In recent years, many advances have been made in the diagnosis and treatment of acute pancreatitis that have lead to a significant reduction in both morbidity and mortality; however, knowledge of the etiology and of the relation between etiology and mortality is far from complete., Aim: To obtain a more comprehensive view of the etiology and mortality of acute pancreatitis in Europe than has been given by previous single-center studies., Methodology: The study comprised 1,068 patients in five European countries who were admitted to hospitals for acute pancreatitis from January 1990 to December 1994. Data for each patient were collected on a standardized form., Results: Of the 1,068 patients (692 men, 376 women; mean age, 52.8 years; range, 10-95 years), 589 had edematous pancreatitis, and 479 the necrotic form. Cholelithiasis (37.1%) and alcohol (41.0%) were the most frequent etiologic factors. In Germany, cholelithiasis and alcohol occurred with similar frequency (34.9 and 37.9%, respectively); in Hungary, alcohol predominates over cholelithiasis (60.7 vs. 24.0%); in France, a small predominance of alcohol was seen (38.5 vs. 24.6%); and in Greece and Italy, there was a clear predominance of cholelithiasis over alcohol (71.4 vs. 6.0% and 60.3 vs. 13.2%, respectively). The differences in the frequency of cholelithiasis and alcohol between Greece and Italy and the other countries were statistically significant (p < 0.01). Eighty-three patients (7.8%) died of acute pancreatitis; 77 (16.1%) had necrotic disease and 6 (1.0%) edematous. There was no statistically significant difference in mortality among the etiologic groups, and no relation was found between mortality and age., Conclusion: Both cholelithiasis and alcohol were main etiologic factors in the more northern countries studied, whereas cholelithiasis alone predominated in the more southern ones. Mortality was high for necrotic pancreatitis; it was similar among the various etiologic groups, and there was no relationship between mortality and age.
