title: Peptic ulcer disease in the Alaska Natives: a four-year (1967-1971) retrospective study.
abstract: A four-year retrospective study of peptic ulcer disease in the Alaska Native confirmed our suspicion of a decreased ratio of duodenal to gastric ulcers. There were 92 patients with duo-denal ulcers, 75 with gastric ulcers, 6 with carcinoma of the stomach and 1 with gastric sarcoma. Ulcer disease in the Alaska Natives differs from ulcer disease among the Southwestern Indians as reported by Sievers.
