Objectives: In recent years, home enteral nutrition (HEN) has been adopted as a feasible and safe form of nutrition for patients undergoing esophagectomy. The aim of this study was to compare the effects of 4 wk of HEN with standard enteral nutrition (SEN) on immune function, nutritional status, and survival in patients undergoing esophagectomy.
Methods: A parallel-group, randomized, single-blind, clinical trial was conducted between April 1 and August 1, 2017. Eighty patients were enrolled in the study and 62 were eligible for analysis. An enteral feeding pump was used to infuse enteral nutrition via jejunostomy tube postoperatively. Patients in HEN group were instructed to independently administer jejunostomy feeds at home. Immune parameters and nutritional indicators were measured at preoperative day 7 and at postoperative day 30.
Results: There were no significant differences in baseline characteristics between the two groups. The levels of immunoglobulin (Ig)A and IgG, which can reflect a patient's immune function, significantly increased in the HEN group compared with those in the SEN group (P = 0.042 and P = 0.003, respectively). Comparing the two groups, 2-y progression-free survival and overall survival had no significant differences in survival curves (P = 0.36 and P = 0.29, respectively).
Conclusion: Four weeks of HEN is a safe and feasible nutritional strategy to improve immune function and nutritional status after esophagectomy. Although there was no significant difference in survival between the two groups, HEN could still be more effective and beneficial than SEN to patients with defective nutritional and immune status.
