Abstract
Background: The safety and potential benefits of home enteral route nutrition (HERN), referring specifically to home enteral nutrition (HEN) and oral nutritional supplements (ONS) in this article, after upper gastrointestinal (GI) resection are inconsistent. Objective: To evaluate the impact of HERN on nutritional status, complications, and quality of life (QOL) after upper GI resection. Methods: This systematic review was conducted in accordance with the PRISMA statement. Nine databases were searched from inception to October 2019. Randomized controlled trials (RCTs) comparing the impact of HERN after upper gastrointestinal resection were included. Relative risk/weighted mean difference/standardized mean difference (RR/WMD/SMD) and corresponding 95% confidence intervals (95% CI) were calculated using fixed- or random-effects models. Results: Overall, 15 RCTs involving 1059 patients were included. Compared with normal oral diet, HERN significantly prevented weight loss (-3.95 vs -5.82 kg; SMD: 1.98 kg; 95% CI: 1.24-2.73); improved added-level of albumin (3.48 vs 2.41 g/L; SMD: 1.36 g/L; 95% CI: 0.81-1.91), hemoglobin (6.54 vs -1.29 g/ L; WMD: 7.45 g/L; 95% CI: 5.05-9.86), pre-albumin (37.59 vs 7.35 mg/L; WMD: 21.6 mg/L; 95% CI: 5.96 -37.24), and transferrin (63.08 vs 50.45 mg/L; WMD: 16.44 mg/L; 95% CI: 13.51-19.38); and reduced the incidence of malnutrition or latent malnutrition (RR = 0.54; P < 0.01). Subgroup analysis based on the approach of HERN showed that weight loss in the HEN subgroup was significantly lower than that of the control group (WMD = 2.69, P < 0.01), while there was no significant difference between the ONS subgroup and the control group (P = 0.1). The same results were found in albumin. Physical function (WMD: 5.29; 95% CI: 1.86-8.73) and fatigue (WMD: -8.59; 95% CI: -12.61, -4.58) dimensions in QOL were significantly better in the HERN group. No significant differences in gastrointestinal and tuberelated complications. Conclusion: HERN improved nutritional status and some dimensions of QOL in upper GI malignancy patients after surgery, without increasing complications. Subgroup analysis showed that HEN experienced more benefits than ONS. (c) 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism. All rights reserved.
