Early diagnosis of chronic pancreatitis: understanding the factors associated with the development of chronic pancreatitis.

The prognosis of advanced chronic pancreatitis (CP) is poor with the mortality rate approximately two-fold higher than the general population according to a survey of the prognosis of CP.　From this standpoint, the concept of early CP was propagated in Japan in 2009 to encourage the medical treatment for the earlier stages of CP.　That is, picking up the patients suspicious for early CP and then providing medical treatment for them are very important not only for patients, but also for health care economics.　In this review, we described some potential factors associated with the development of CP (alcohol, smoking, past history of acute pancreatitis, aging, gallstone, and gender) that are extremely important to discover patients with early-stage CP.
