AbstractThe impact of serum prealbumin in patients with esophageal carcinoma after undergoing esophagectomy remains unclear, we speculated that serum prealbumin is associated with anastomotic leak (AL) after surgery, low serum prealbumin level may lead to AL. The aim of the study was to evaluate the relationship between serum prealbumin levels and AL after esophagectomy, to explore the value of serum prealbumin as an early predictor of AL after esophagectomy.Between January 2014 and December 2018, 255 patients were enrolled in this study, their basic characteristics and perioperative serum prealbumin levels were retrospectively analyzed. Statistical analysis by t test, nonparametric test and logistic regression were used to analyze data for patients with and without AL. Based on a receiver operator characteristic curve, a cut-off value for serum prealbumin levels as a predictor of AL was determined.Among the 255 patients, 18 patients were diagnosed with AL. The overall AL rate was 7.0% (18/255) including 12 cases of intrathoracic AL and 6 cases of cervical AL. By univariate analysis, we identified postoperative serum prealbumin level as a risk factor for AL (P < .001). Multivariate analysis also demonstrated postoperative serum prealbumin level (P = .028) to be an independent risk factor for AL. The best cut-off value of postoperative serum prealbumin level was 131 mg/L for predicting AL, with 83.3% sensitivity and 72.2% specificity.Postoperative serum prealbumin level was significantly associated with AL. it may help the early prediction of postoperative AL.Copyright © 2022 the Author(s).
