[Hyperplastic Brunner glands and chronical renal insufficiency (author's transl)].

Enlarged Brunner glands (EBG) are an occasional finding in upper gastro-intestinal barium studies. The clinical manifestations vague upper abdominal symptoms or bleeding are rare. Brunner gland secretion is stimulated by different stimuli but especially by secretin. In our report E.B.G. has been observed in 9/15 chronically hemodialysed patients. This uncommon frequence of E.B.G. can be related to the high blood levels of secretin found in patients with chronic renal failure. E.B.G. could explain some of the gastro-intestinal complications occuring in these patients.
