Risk factors for anastomotic leakage after surgical resections for esophageal cancer.

Risk factors for anastomotic leakage after surgical resections for esophageal cancer.

Surgery for esophageal cancer is a challenging procedure that is associated with a high rate of complications such as sepsis, nutritional disorders, and anastomotic leakage (AL). The rate of complications following esophageal surgery rises exponentially in the presence of risk factors. This study aims to identify the risk factors for AL following esophageal cancer surgery./r/nIn this retrospective study, we recorded comorbidities, tumor specific factors, nutritional status, and surgical complications of all patients who underwent surgical resections for esophageal cancers between January 2015 and December 2019. The occurrence of potential risk factors for AL was compared between groups with and without AL. We analyzed the categorical variables by Chi-square or Fisher’s exact test, and the continuous variable by the Mann-Whitney U test and multivariable regression analyses./r/nFrom 92 patients, AL was found in 12 (13%) patients. All cases with AL had hypoproteinemia; a protein level < 5 g/dl was an independent risk factor for AL (p value 0.009). The logistic regression analysis showed a positive correlation between hypoproteinemia and AL (coefficient 1.83, significance 0.01). Additionally, squamous cell carcinoma (SCC) of the esophagus had a positive correlation with AL (coefficient 1.89, significance 0.01)./r/nIn our study, hypoproteinemia and SCC were significant risk factors for AL after esophageal cancer surgery. Optimization of preoperative hypoproteinemia using a standardized nutritional protocol is recommended. More research is essential to determine the correlation of SCC with AL.
