[Chronic pancreatitis: natural history and development in relation to alcoholism].

: 42 cases of chronic pancreatitis treated between 1976 and 1986, presenting 0.2% of all patients seen at the surgical clinic in the same period, have been reviewed. 37 patients (88%) were alcoholics and the prevalence of males was 83%. -Study of dietary habits showed a very high alcohol intake of 135.3 g alcohol per day, contrasting with the control group's alcohol consumption of 44.9 g per day. Alcohol intake calculated per life of patient with chronic pancreatitis represented 850.4 kg, whereas the control group consumed 344.1 kg (beer and wine). -Patients with chronic pancreatitis had started excessive alcohol consumption at an average age of 18 +/- 2 years and continued for an average of 18.0 +/- 1 years. These data correspond to zone A, i.e. Southern Europe. The evolution was analyzed with regard to persistence or cessation of alcoholism. Repeated attacks of chronic pancreatitis were seen in both groups. Patients abstaining from alcohol had only one attack during an average period of 10 years. Painful recurrences after surgery seem to be more frequent with persistent alcoholism (4 out of 5 patients), whereas in 15 patients without alcoholism they were observed only 3 times. -This shows that alcoholism remains the main factor in the natural history and evolution of chronic pancreatitis.
