Classification of chronic pancreatitis.
Chronic pancreatitis (CP), defined as a continuing inflammatory disease of the pancreas characterized by irreversible morphological changes which typically cause abdominal pain and/or permanent impairment of pancreatic function, has proved resistant to categorization. The disease may present clinically either with an individual symptom or a combination of symptoms associated with loss of pancreatic function. The single most frequent symptom of CP is pain, either in the form of intermittent episodes or in a more chronic or persistent pattern. The natural history of CP is usually characterized by progression of tissue damage and various degrees of exocrine and endocrine pancreatic insufficiency, which will become apparent over time. The main reason for the lack of guided strategies in the therapeutic management of CP is the absence of a clinically applicable classification of CP. In the past, several classifications have certainly contributed to a better understanding of the pathogenesis and pathophysiology of CP. The meetings in Marseilles (1963 and 1984), Cambridge (1984) and in Rome (1985) added a great deal of information to our knowledge of the pathogenesis and evolution of CP. More recent work on understanding the temporal course of CP led to the Zurich international classification which has been used to define patient cohorts in recent studies of patients undergoing surgery for CP. In order to combine clinical experience in the field of CP with progress in diagnostic methods and new molecular technologies for the assessment of CP, a classification of CP based on key clinical aspects is crucial. A new classification should first be validated to determine whether it can be applied to the majority of patients with CP, and then the value of such a classification needs to be tested in our understanding of the natural course in different etiologies (progression, arrest, regression) and most importantly, to study the clinical outcome when different therapeutic strategies are applied.
