[Duodenitis in stomach diseases--a quantitative histologic study].

The coincidence of gastric diseases and chronic duodenitis has been investigated on biopsies and preparations of stomach and duodenum by a quantitative histologic method. The histologic classification of duodenitis was made according to Whitehead et al. 9 of 40 patients with a chronic atrophic gastritis had a duodenitis grade 1. 10 of 40 patients with a chronic gastric ulcer had a duodenitis grade 1 and one patient grade 2. 14 of 40 patients with a gastric cancer had a duodenitis grade 1. By statistical investigations it has been found out that patients with an ulcer or cancer do not have duodenitis more often than patients with gastritis. A possible duodenitis concerning the investigated gastric diseases is mainly due to the chronic gastritis that also could be proved by all patients suffering from ulcer or cancer.
