Changes in the nutritional status of elderly patients after esophagectomy

Background Esophagectomy is a highly invasive procedure for patients aged > 70 years. Here, we compared the actual nutritional status of older and younger patients who underwent esophagectomy. Methods A total of 118 patients who underwent radical esophagectomy between April 2013 and December 2016 were enrolled and divided into two groups based on age: group A (n = 41; >= 70 years) and group B (n = 77; < 70 years). Data pertaining to body mass index and nutritional variables (albumin; total cholesterol; cholinesterase; and prealbumin) were retrospectively analyzed preoperatively and at 3, 6, and 12 months postoperatively. Results Significant preoperative between-group differences were found in the cholinesterase, albumin, and prealbumin levels. The body mass index gradually decreased over the first 12 months after surgery in both groups, without significant between-group differences. Significant differences were observed in prealbumin and cholinesterase levels at 3 months postoperatively. 1 year postoperatively, both groups showed slight improvements; however, the between-group differences were not statistically significant. Group A had a significantly lower amount of the degree of decrement of BMI and chE than group B. Conclusion Thus, patients aged > 70 years can recover within 12 months of esophagectomy.
