[Comparative radiological and morphological study of the human pancreas. 2. Morphometrical investigation of the human pancreatic duct system (author's transl)].
The diameter and the thickness of all the side ducts were measured in 27 normal or nearly normal human pancreata. The obtained data (about 5,000 pairs of Figures) were evaluated statistically. The relative thickness of the walls increases with growing distance from the papilla as well as with the reduction of the diameter of the side ductes. Beyond the age of fifty the diameter of the ducts is 10--13% higher than in younger age. In a logarithmical system there is a strong correlation between the diameter and the thickness of the side ducts, slightly diminished with aging. The regression coefficient is slightly diminished with aging. But the variance of the wall thickness in respect to the diameter of the ducts shows such a rise with aging, that the number of ducts with relatively thick and small walls increase with aging. By reason of the logarithmic system the positive variance has a higher weight. Therefore periductal fibrosis increases with aging.
