Brief description/objective

140 patients with alcoholic acute (recurrent) pancreatitis were enrolled in a prospective long-term study over the last 16 years. Regular control studies regarding progression to advanced chronic pancreatitis were performed. Based on long-term outcome the patients were classified into two groups: group A (n = 109; 77.8%) with progression to advanced chronic pancreatitis (84% with calcification, 95% with exocrine insufficiency) and group B (n = 31; 22.2%) without progression (no calcification, no exocrine insufficiency). The two groups were comparable in age, sex, and mean duration of disease from onset (13.1 +/- 5.2 vs. 13.8 +/- 4.9 years). Surgery for pseudocysts was performed in 47% of group A and in 29% of group B. In group B, no pancreatic duct dilatation occurred (in 86% > 8 years from onset). However, 4 of 7 patients with adequate histology showed unequivocal chronic pancreatitis. Surprisingly, all patients of group B except two got spontaneous lasting pain relief irrespective of alcohol intake or normal pancreatic function. Our findings indicate that a subgroup of alcoholic acute pancreatitis does not progress to advanced chronic pancreatitis. This subgroup may be identical with "small duct" chronic pancreatitis. The factors responsible for progression (group A) or nonprogression (group B) remain to be elucidated.
