Home enteral nutrition for postoperative elderly patients with esophageal cancer.

BACKGROUND

The clinical value of enteral nutrition (EN) after radical resection of esophageal cancer (EC) has been well recognized during hospital stay; however, whether using EN agents should be continued at home after the patient is discharged remains unclear, especially for the elderly postoperative patients. Here we investigated the effects of continued EN on nutrition and immune status in elderly patients who had undergone radical EC surgery.

METHODS

Sixty eligible elderly patients undergoing surgical treatment for EC in our center during the period from October 2016 to October 2018 were randomly divided into EN group and control groups, with 30 patients in each group. Among them, the EN group continued to take an orally administered EN agent (Ensure®) daily in addition to daily routine diets after discharge; however, patients in the control group only received regular diets after discharge. The nutritional status and immune indicators were evaluated at discharge and 4 and 8 weeks after discharge (weeks 4 and 8) and compared between EN and control groups.

RESULTS

Body mass index (BMI), Patient-Generated Subjective Global Assessment (PG-SGA) score, hemoglobin, serum albumin, serum prealbumin, CD4 and CD8 T cell counts, CD4/CD8 ratio, IgA, IgG, and IgM showed no significant difference between EN group and control group at discharge (all P>0.05). In week 4, the serum prealbumin level was significantly higher in the EM group than in the control group (P<0.05). In week eight, the EM group had significantly higher BMI, PG-SGA score, serum albumin, serum prealbumin, CD4 and CD8 T cell counts, CD4/CD8 ratio, IgA, IgG, and IgM than the control group (all P<0.05).

CONCLUSIONS

Home EN helps improve immune function in elderly patients who have undergone radical surgery for EC and is worthy of clinical promotion. To optimize its efficacy, a home EN should last no less than eight weeks after discharge.
