[Coincidence of chronic pancreatitis and duodenitis].

Biopsies taken from various regions of the duodenal mucosa were investigated with a quantitative histological method with a view to frequency, quantity, and localisation of the duodenitis in clinically proven chronic pancreatitis. The histologic classification of duodenitis was made according to Whitehead et al. Out of 46 patients suffering from a chronic pancreatitis, 19 had a duodenitis grade 1 in the pars superior and pars descendens. A more frequent occurrence of duodenitis with concomitant chronic gastritis or a pathologic condition of the bile duct or a chronic alcohol abuse could not be proved statistically.
