Abstract
Background
Post-operative body weight loss (BWL) of patients who underwent esophagectomy is common. One month after esophagectomy, some patients lose weight remarkably, and others not. If preoperative or operative risk factors influencing body weight loss are identified, it will be possible that nutritional intervention is given to the patient having these risk factors.
Methods
In our department, the dietician stays in a surgical ward for nutritional management of patients. Ninety-two patients who underwent esophagectomy for esophageal cancer in 2016 were reviewed. Pre-operative and operative factors were correlated with post-operative BWL. The cut-off value of BWL 1 month after esophagectomy was defined with 75 percentile.
Results
The median body weight change was -4.8% (-18.5% ∼11.7%). The patients were divided into two groups; 24 patients with ≥ 7.3% of BWL (severe BWL group) and 68 with < 7.3% of BWL (mild BWL group). Patients’ characteristics or post-operative morbidities were not statistically different in these 2 groups. The incidence of patients with reconstruction using a colon or jejunum was higher in severe BWL group. Pre-operative body weight, body mass index, and the value of prealbumin was higher in severe BWL group. On postoperative 14 day, the patients in severe BWL group were likely to have lower energy intake per kilogram of pre-operative body weight. On multivariate analysis, high body mass index [odds ratio = 5.90; 95% confidence interval (CI) = 1.03–47.8; P = 0.046], upper location of tumor [odds ratio = 3.38; 95%, CI = 1.04–11.4; P = 0.043] were independently associated with severe BWL at 1 month after surgery.
Conclusion
High body mass index of ≥ 25, upper location of tumor were unfavorable risk factors for weight loss 1 month after esophagectomy for esophageal cancer.
