Effect of cessation of alcohol use on the course of pancreatic dysfunction in alcoholic pancreatitis

Abstract

Exocrine pancreatic function was studied sequentially by means of the secretin-cerulein test in 32 patients with alcoholic chronic pancreatitis to elucidate the long-term course of pancreatic dysfunction, and to determine whether the cessation of alcohol use had any influence on the natural history of pancreatic functional changes caused by this disease. At initial studies, 5 patients had normal pancreatic function, and the remaining 27 had pancreatic insufficiency, which was mild to moderate in most subjects. The final studies, carried out at an average of 7.3 yr (range, 4-11 yr) after the first, showed a significant deterioration in pancreatic function, both in patients who stopped alcohol after the initial study (n = 18) and in those who did not (n = 14). The deterioration, however, was significantly less marked in patients who stopped drinking alcohol than in those who continued. These data indicate that pancreatic functional changes caused by alcoholic pancreatitis progress even after cessation of alcohol use; however, the progression is slower and less severe when alcohol intake is stopped.
