Usefulness of delta neutrophil index as a biomarker to predict postoperative complication in patients who underwent esophagectomy

Abstract

Esophagectomy demonstrates a high incidence of complications owing to its complexity and invasiveness; hence, early detection of complications is important. We aimed to evaluate the predictive value of the delta neutrophil index (DNI) for complications after esophagectomy. We retrospectively analyzed patients who underwent esophagectomy in the department of general surgery at a single institution between January 2011 and October 2020. Patient characteristics, laboratory findings, and clinical outcomes were assessed. Fifty-seven patients were enrolled in this study, of whom 31 (54.4%) had complications. The complication group had significantly longer mean mechanical ventilation, hospital stay and intensive care unit stay periods, and higher acute physiology, age, chronic health evaluation score and mortality rate than the noncomplication group. DNI on postoperative day (POD) 2 was also significantly higher in the complication group. Logistic regression analysis showed that DNI on POD 2 was an independent risk factor associated with the complications. Receiver operating characteristic curve analysis showed that the area under curve of DNI on POD 2 was 0.712 (cutoff value: 2.15%, sensitivity 61.5%, and specificity 70.8%). Our study indicated that postoperative DNI can be useful as an early predictive biomarker of the complications after esophagectomy.

Effect of inspiratory muscle training in esophageal cancer patients receiving esophagectomy: A meta-analysis of randomized controlled trials

“…Additionally, the use of anesthesia, sedation, analgesics, and damage to the diaphragm and chest wall muscles can lead to a substantial decline in postoperative cardiopulmonary function and physical mobility of patients [ 1 – 5 ]. The incidence of complications after esophageal cancer surgery remains relatively high [ 6 ]. Maintaining good respiratory status is of paramount importance for promoting rapid recovery in postoperative esophageal cancer patients.…”
