Abstract
Malnutrition is reported to be an inevitable consequence of total gastrectomy, although there are few data to support this contention. Six patients of median age 63 years underwent total gastrectomy for malignancy. At follow-up (median 45 months, range 25–60 months) each patient was clinically tumour-free and underwent dietary assessment, faecal fat and nitrogen measurement and routine haematological testing. Protein and fat stores, measured by neutron activation analysis and the tritiated water dilution technique, were compared with the same measurements made before operation and with predicted values. Mean(s.d.) dietary intake (2224(381) kcal day−1 and 81(15)g protein day−1) met the patients' estimated requirements. Mean(s.d.) serum albumin and faecal nitrogen values were normal but there was notable steatorrhoea (21(17) g day−1). Body composition measurements revealed profound deficiencies of body-weight (P < 0·02), protein (P < 0·01) and fat (P < 0·02) before operation which were not corrected by an apparently curative total gastrectomy (P < 0·05), although further deterioration was prevented.
