[The Wirsung's duct of in surgical chronic pancreatitis. Radiologial and anatomical study (author's transl)].

On the basis of pancreatography findings and the study of operative specimens in 32 cases of duodenopancreatectomy, it was possible to distinguish two groups according to whether or not the duct of Wirsung was dilated. When the duct was not dilated, fibrosis was relatively marked, but disseminated and more notable in sections of the head than in sections of the isthmus. Lithiasis was essentially cephalic, but distributed more or less equally between the duct of Wirsung and the canaliculi. When the duct was dilated, there was marked fibrosis, distributed equally. Lithiasis was radiologically diffuse throughout the organ, but situated in particular in the duct of Wirsung itself.
