Improvement of nutritional support strategies after surgery for benign liver tumor through nutritional risk screening: a prospective, randomized, controlled, single-blind clinical study

The rising of individualized therapy requires nutritional risk screening has become a major topic for each particular disease, yet most of the screenings were for malignancies, less for benign diseases. There is no report on the screening of patients with benign liver tumors postoperatively. We aim to evaluate the nutritional support strategies post operation for benign liver tumors through nutritional risk screening.Methods: In this prospective, randomized, controlled study, 95 patients who underwent hepatectomy for benign tumors were divided into two groups. Fifty patients in the control group were given routine permissive underfeeding nutritional supply (75 kJ/kg/d), and 45 patients in the experimental group were given lower energy (42 kJ/kg/d) in accordance of their surgical trauma. Routine blood tests, liver/kidney function were monitored before surgery and at the day 1, 3, 5, 9 after surgery, patients were observed for the time of flatus, complications, length of hospitalization (LOH), nutrition-related costs, and other clinical parameters. This completed study is registered with Clinicaltrials.gov, number NCT01292330.Results: The nutrition-related expenses (494.0±181.0 vs. 1,514.4±348.4 RMB, P 0.05) and the total hospital costs (18,495.2±4735.0 vs. 21,432.7±8,291.2 RMB, P 0.05) for patients in the experimental group were significantly lower than those in the control group. Meanwhile, the lowered energy supply after the surgeries did not have adverse effects on clinical parameters, complications, and LOH.Conclusions: Patient with benign liver tumors can adopt an even lower postoperative nutritional supply that close to that for mild non-surgical conditions, and lower than the postoperative permissive underfeeding standard.
