An improved knowledge of the natural history is the indispensible basis for a rational concept in regard to the diagnosis, classification, understanding and management of pain in chronic pancreatitis. Unfortunately, data on the natural history of CP are scarce and conflicting. Some relevant observations of our prospective long-term study of a mixed medical-surgical cohort comprising 207 patients with alcoholic CP (mean follow-up 17 years from onset) are summarized. In early-stage CP, episodes of recurrent pancreatitis were predominant. Severe persistent pain was typically associated with local complications (mainly postnecrotic cysts in 54%; symptomatic cholestasis in 24%) relieved definitely by a drainage procedure. Lasting pain remission was documented in >80% of the whole cohort within 10 years from onset in association with marked pancreatic dysfunction. From our experience, the relief of "chronic" pain regularly follows selective surgery tailored to the presumptive pain cause or it occurs spontaneously in uncomplicated advanced CP (excluding narcotic addiction).(Internal Medicine 40: 368-375, 2001).
