Abstract
The effect of nutritional status on the morbidity and mortality of major gastrointestinal surgery for benign disease was studied in 32 patients. Malnutrition was defined as a serum albumin <3.5 g/dl and a recent weight loss >10%, in addition to any two of the following: weight for height, mid-arm circumference or triceps skin-fold thickness <10th percentile. The morbidity and mortality in the 17 malnourished patients was 59% and 29%, respectively, compared with 20% and 7% in 15 well-nourished patients matched for age and operative procedure (p < 0.05). After operation, the mean duration of inadequate oral nutritional intake period (IONIP, defined as a caloric intake >60% requirement) was 11.9 days ± 2.9 (SEM) in well-nourished patients compared with 30.5 days ± 3.7 in the malnourished group. The longer IONIP in malnourished patients was a consequence of the higher morbidity in this group, thus warranting the consideration of supportive (postoperative) parenteral nutrition in malnourished patients who undergo major gastrointestinal surgery for benign disease.
