Abstract

Background: The number of geriatric patients with esophageal cancer is increasing in step with the aging of the population. Geriatric patients have a higher risk of postoperative complications, including delirium that can cause a fall or impact survival. Therefore, it is very important that we evaluate risks of postoperative complications before surgery. The aim of this study was to predict postoperative delirium in elderly patients. Methods: We retrospectively reviewed the medical records of 91 patients aged 75 years and over who underwent esophagectomy between January 2006 and December 2014. We investigated the association between postoperative delirium and clinicopathological factors, including comprehensive geriatric assessment (CGA). Results: Postoperative delirium developed in 24 (26 %) patients. Postoperative delirium was significantly associated with low mini-mental state examination (MMSE) and high Geriatric Depression Scale 15 (GDS15), which are components of CGA, and psychiatric disorder (P < 0.0001, P = 0.002, and P = 0.017, respectively). With multiple logistic regression analysis, MMSE (odds ratio [OR], 1.4; 95 % confidence interval [CI], 1.2–1.6; P < 0.0001] and GDS15 (OR, 1.3; 95 % CI, 1.1–1.6; P = 0.004) were independently associated with postoperative delirium. Conclusions: Preoperative CGA, especially MMSE and GDS15, was useful for predicting postoperative delirium in elderly patients undergoing esophagectomy for esophageal cancer. Intervention by a multidisciplinary team using CGA might help prevent postoperative delirium.
