Abstract
Twelve patients with proximal gastric resection for cancer of the proximal part of the stomach were included in a follow-up examination 2–8 years after the operation. Six were underweight, 1 had mild anaemia, and 1 had definite X-ray signs of osteoporosis. B12 absorption was normal in 7; iron absorption was reduced, while calcium absorption was normal, in all. External pancreatic function was not definitely reduced. About half the patients had postcibal complaints in the form of the small stomach syndrome and regurgitation with pyrosis, which were not found after total gastrectomy.
