Abstract
ObjectiveThe objective of this study was to evaluate, through multivariate analysis, the configuration of nutritional predictors that impact the development pharyngocutaneous fistula (PCF) after total laryngectomy. MethodsA retrospective cohort study carried out on 203 consecutive patients with laryngeal squamous cell carcinoma who underwent total laryngectomy with neck dissection between June 2015 and June 2020. Patients with risk factors for PCF formation, other than malnutrition, were excluded to eliminate the potential impact of that risk factors on PCF formation and to make the study group homogenous. Five parameters were evaluated including preoperative serum prealbumin, albumin and transferrin levels, Body Mass Index (BMI) and Malnutrition Screening Tool (MST). ResultsUnivariate analysis revealed that preoperative prealbumin, albumin and transferrin levels significantly correlated with PCF development. Multivariate logistic regression analysis revealed that preoperative prealbumin level was the best independent nutritional predictor of PCF (P value <0.001, odd ratio 11.951 [95% CI 3.686-38.749]) followed by preoperative albumin (P value 0.006, odd ratio 3.985 [95% CI 1.485- 10.694]). ConclusionPreoperative prealbumin level is considered the best independent nutritional predictor of PCF. It should be used to evaluate the nutritional status of patients undergoing total laryngectomy and hence their need for nutritional support.
