Multicenter pathological study of chronic pancreatitis. Morphological regional variations and differences between chronic calcifying pancreatitis and obstructive pancreatitis.
To examine previous work carried out at a single center, i.e., France, on the pathologic features of chronic pancreatitis and to examine geographic differences, 359 cases of chronic pancreatitis from five centers were studied pathologically and the results analyzed according to appropriate statistical methods. It was found that it was easy to separate chronic calcifying pancreatitis from obstructive pancreatitis occurring distal to obstruction to the pancreatic duct by pathological means. On the other hand, geographic differences between France, Italy, Brazil, and South Africa, although present, were not sufficient for identification of a specific profile for each of the countries studied, and it was found that the minor differences were probably dependent on environmental rather than racial factors.
