Acute and chronic pancreatitis: an up-date.
According to the 1988 Marseilles-Rome classification inflammatory pancreatic diseases are represented by acute (AP) and chronic pancreatitis (CP), pancreatic fibrosis and abscesses (due to infection of cystic cavities). Each form is defined by specific etiological, pathomorphological, functional and evolutive aspects. In our experience with 348 AP cases, gallstones and chronic alcohol abuse, alone or together, represent the major causative factors (over 70% of cases). Mortality observed in necrotizing AP only, varies from 26% of idiopathic to 8% of biliary cases. Ductal scars, exocrine and endocrine impairment were observed in about 45% and 20% respectively as sequelae of necrotizing AP, whatever the etiology. As far as CP is concerned, the main etiological factor is chronic alcohol consumption (82% of cases). The clinical evolution of CP may be roughly divided in two phases, the earlier (within 5 years from onset) characterized by frequently recurrent pain, calcifications and cystic cavities and the later when pain spontaneously regresses and steatorrhea and diabetes tend to appear. Heavy alcohol intake, smoking and frequent relapses are related to a less favourable course. About 60% of the patients underwent surgery within 5 years from onset. Pain relief was achieved in the large majority. Reduction in alcohol intake and the natural tendency of the disease to burn out, probably aid pain relief. Mortality in CP is due to diseases secondary to alcohol and smoking abuse (cardiovascular and neoplastic) more than to CP alone. We believe that multiple parameters are required for a complete definition of each pancreatic patient.
