[Duodenogastric-reflux-favouring behaviour of the pylorus in patients with gastritis and duodenitis (author's transl)]. / Duodenogastralen Reflux förderndes Pylorusverhalten bei Gastritis und Duodenitis.

The pylorus was observed gastroscopically, biopsies of the gastral and duodenal mucosa were taken in 183 patients. If the mucosa did not show signs of inflammation, reflux-favouring behaviour of the pylorus (permanently being ajar or acting hyperkinetically) was rare. In patients with gastritis it was significantly more frequent. If the inflammation concerned the mucosa of the stomach as well as that of the duodenum the reflux-favouring behaviour of the pylorus was especially frequent.

[Double pylorus (author's transl)]. / Doppelpylorus.

Smith and Tuttle described in 1969 for the first time a double pylorus; since then this anomaly has been found repeatedly. The pathogenesis is still discussed; the anomaly may be congenital or acquired. A case report is given of a patient with double pylorric ulcer.

[Duodenitis and its correlation to diseases of the neighbouring organs and to duodeno-gastric reflux (author's transl)]. / Duodenitis, ihre Beziehungen zu Erkrankungen benachbarter Organe und duodeno-gastralem Reflux.

In 26,4% of patients (n = 201) with disturbances in the upper abdomen a serious proximal duodenitis was found. Older persons were more often concerned. A duodeno-gastric reflux was more frequent in presence of a serious duodenitis than in normal mucous membrane. Duodenitis was significantly more frequent in patients with atropic gastritis, ventricular ulcers and cholecystectomy. In the patients with reflux of bile the cases of antrum gastritis, with diseases of the biliary tract and nonoperated biliary tract diseases were significantly correlated with duodenitis; in atrophic gastritis as well as in gastric ulcers a duodeno-gastric reflux was found more than accidentally.
