The impact of preoperative chemotherapy/radiation on esophageal anastomotic leaks (ALs) and the correlation between AL severity and mortality risk have not been fully elucidated. We hypothesized that lower severity ALs have a similar risk of mortality compared to those without ALs, and preoperative chemotherapy/radiation increases AL risk.
Methods
The 2016-2017 American College of Surgeons National Surgical Quality Improvement Program’s procedure-targeted esophagectomy database was queried for patients undergoing any esophagectomy for cancer. A multivariable logistic regression analysis was performed for risk of ALs.
Results
From 2042 patients, 280 (13.7%) had ALs. AL patients requiring intervention had increased mortality risk including those requiring reoperation, interventional procedure, and medical therapy (P < .05). AL patients requiring no intervention had similar mortality risk compared to patients without ALs (P > .05). Preoperative chemotherapy/radiation was not predictive of ALs (P > .05).
Conclusion
Preoperative chemotherapy/radiation does not contribute to risk for ALs after esophagectomy. There is a stepwise increased risk of 30-day mortality for ALs requiring increased invasiveness of treatment.
