![]() ![]() An experimental study of protein and fat assimilation after total gastrectomy. Studies on Fe absorption following partial gastrectomy. ![]() Iron metabolism in patients following partial gastrectomy. ![]() Hematologic changes following gastric surgery with special reference to the serum levels of vitamin B 12 and iron. True, there are certain metabolic alterations which are inherent in the anatomic changes wrought by gastric surgery, but we must not be overawed by these impediments, and, above all, we must not forget that a patient exists surrounding the stomach, so that the results of gastric surgery must be profoundly influenced by extragastric and even extrasomatic or psychic factors.īirnbaum, D., et al. These derangements manifest themselves in various syndromes which may be grouped as: (1) deficiency syndromes, (2) cardio-respiratory syndromes, (3) syndromes of homeostatic over-reaction, and (4) syndromes reflecting discoordination of normal feedback mechanisms.Įlucidation of the basic etiologic physiology has tremendously enhanced our comprehension of pathogenesis but considerable gaps in knowledge still hinder our goal of a postgastrectomy patient without dyspepsia. Resection of the stomach-total, proximal, or distal-accompanied or not by vagisection, is followed by physiologic derangements which derive from mechanical and anatomic alterations, functional disorganization, and metabolic aberration.
