Risk Factors for Weight Loss 1 Year After Esophagectomy and Gastric Pull-up for Esophageal Cancer

Loss of body weight is regarded as a marker of malnutrition after esophagectomy. This study investigated changes in body weight and risk factors for weight loss after esophagectomy for esophageal cancer.
We retrospectively reviewed records of 181 patients who underwent esophagectomy and gastric pull-up from 2012 to June 2016. Patients with operative mortality and recurrences were excluded. Percent change in body weight was defined as change in body weight (%) = (1-year body weight − preoperative body weight) × 100/preoperative body weight.
Mean age of patients was 62.98 ± 8.23 years with 164 men (90.6%). Mean preoperative body weight was 63.12 ± 9.42 kg, and body weight at 1 year was 56.04 ± 8.59 kg. Mean change in body weight was − 10.95 ± 7.50%, and 98 (54.1%) patients showed weight loss more than 10% compared to initial body weight. Univariable analysis showed that initial body weight, narrow gastric tube, thoracotomy, laparotomy, and postoperative vocal cord palsy (VCP) were related to more than 10% weight loss. Multivariable analysis showed that initial body weight (odds ratio [OR] = 1.041, p = 0.031) and postoperative VCP (OR = 2.772, p = 0.025) were adverse risk factors for weight loss 1 year after esophagectomy, whereas conduit type, route of reconstruction, postoperative complications, anastomotic complications, minimally invasive esophagectomy, and adjuvant therapy were not.
Initial body weight and postoperative VCP were related to weight loss. Patients with VCP need additional nutritional monitoring and support.
