Background Esophagectomy is the surgical excision of part or all of the esophagus and is associated with both common and serious complications. Various comorbidities, such as diabetes mellitus, smoking, and congestive heart failure (CHF), have been detected in individuals who have undergone esophagectomy. This study investigates the association of baseline characteristics and comorbidities with postoperative complications. Methods A retrospective cohort study based on data from the National Surgical Quality Improvement Program database was conducted, evaluating 2,544 patients who underwent esophagectomy between January 2016 and December 2018. Data included baseline characteristics, established comorbidities, and postoperative complications within 30 days of the procedure. Risk-adjusted and unadjusted logistic regressions were used to assess the odds of postoperative complications against baseline characteristics. Results The majority of our population were white males (80.8% male; 78.2% white), with a mean age of 63.5 years. More than half of the patients were overweight or obese. A minority of our patients had a smoking history, weight loss, diabetes mellitus, chronic obstructive pulmonary disease (COPD), or CHF. The most frequent postoperative complications were as follows: return to the operating room (15.7%), anastomotic leak (12.9%), pneumonia (12.7%), bleeding/transfusions (11.8%), readmissions (11.4%), and unplanned intubation (10.5%). Adjusted associations for odds of experiencing a postoperative complication were found to be statistically significant for age (odds ratio [OR] 1.02, 95% confidence interval [CI] 1.01-1.03, and < 0.001), operation time (OR 1.002, 95% CI 1.001-1.003, and < 0.001), race (not white) (OR 1.76, 95% CI 1.26-2.47, and = 0.001), BMI (underweight) (OR 2.18, 95% CI 1.36-3.50, and = 0.001), smoking (OR 1.42, 95% CI 1.14-1.76, and = 0.001), and chemotherapy and/or radiation (OR 0.82, 95% CI 0.68-0.99, = 0.038). Conclusions Our study found that age, operation time, nonwhite race, underweight BMI, and smoking were independently associated with an increased risk of developing a postoperative complication following esophagectomy. Additionally, neoadjuvant chemotherapy and/or radiation are associated with a decreased risk. Understanding how baseline characteristics and comorbidities can affect rates of postoperative complications may help to adjust care for patients in both pre- and postoperative settings.
