[Radiographic examination of the stomach in Greenlanders].

X-ray examinations of the stomach and duodenum from a two year period of 135 Greenlanders and an equivalent number of Danes were reviewed in order to diagnose all radiological lesions. The results are presented. In 37% of the Greenlanders and 51% of the Danes, x-rays showed normal findings. Peptic ulcerations were diagnosed for the first time in 2.4% of Greenlanders over the age of 15 years. The incidence of gastric ulcer was 1.5% and of duodenal ulcer 0.9%. The male/female ratio was 1.3 in Greenlanders. The esofagus and cardia region of the Greenlanders revealed many serious lesions, emphasizing the importance of further investigations in this area. The incidence of peptic ulcer disease and gastric ulcer is higher than the incidence in Denmark but approximately the same as in the Faroe Islands. The incidence of duodenal ulcer is found to be lower among Greenlanders than in the other two populations.
