[Duodenal ulcer in a newborn infant with gastro-intestinal hemorrhage (author's transl)].

A newborn infant was transferred to our hospital because of gastro-intestinal hemorrhage, starting a few hours after birth. Because of fetal distress a cesarean section had been necessary. The clinical examination as well as the results of the laboratory tests revealed nothing abnormal. In an upper gastro-intestinal X-ray series there was evidence for a duodenal ulcer. Under conservative treatment the baby recovered and has remained in a good condition without any bleeding episode until now. A repeat upper gastro-intestinal X-ray series was done at the age of 5 months and no evidence of ulceration could be found. The incidence and the reason of such an ulcer in the new born period is shortly discussed.
