The study was performed in 64 post mortem ductograms of pancreata, missing any inflammatory and/or neoplastic alterations in extensive histological investigations by whole organ sections. The pancreatic duct was measured in the radiograms. From these measured values and by mean of a computer program of a cubic spline function the straightened pancreatic ducts were plotted. The number, the length and the amplitude of ductal deviations were measured in these plots. Luminal dilatations were found in all organs, ranging from 0.5 mm to 6 mm and more. Their frequency was significantly lowered in young people (11-30 years).
