[The natural history and physiopathology of chronic pancreatitis].
Recent longitudinal studies have improved the knowledge of the natural history of chronic pancreatitis. This disease is mainly induced by alcohol abuse. Mean age at onset of the disease is 40 years. First symptoms are generally pain, often related to acute pancreatitis. Over the first five years of course, complications as pseudocysts or common bile duct stenoses can occur, often necessitating surgical treatment. In the late course, the disease becomes less symptomatic but the risk of diabetes mellitus increases. Occurrence of pancreatic calcifications is observed with time in the majority of patients. Chronic pancreatitis is associated with overmortality but the causes of death are mainly extrapancreatic (alcoholic liver disease and cancers). Abnormalities of pancreatic secretion induced by alcohol abuse play an important role in the pathophysiology of the disease: it is possible that the decrease of concentration of the "pancreatic stone protein" promotes formation of calcifications. Direct toxicity of alcohol is another possible factor.
