Comparative radiological and morphological study of human pancreas. Pancreatitis like changes in postmortem ductograms and their morphological pattern. Possible implication for ERCP.

A postmortem study by ductography and histology was performed on 69 human pancreata with no clinical or histological signs of chronic pancreatitis. The ductograms, supplemented by five postmortem ductograms of chronic pancreatitis, were independently evaluated by six clinicians, skilled in ERCP; the degree of alteration was estimated by simple rating, forced choice rating, and by determination of the grade of chronic pancreatitis, Histologically, the amount of intraductal epithelial proliferation, periductal, intralobular and perilobular fibrosis, intraductal protein plugs, and fat necrosis was determined by semiquantitative methods. The six ductographical evaluations significantly differed in the level of their data, but corresponded in the range of distribution.
