Abstract
Purpose
Postoperative anastomotic leakage is the most frequent short-term complication of esophageal atresia repair in neonates. We conducted this study using a nationwide surgical database in Japan to identify the risk factors for anastomotic leakage in neonates undergoing esophageal atresia repair.
Methods
Neonates diagnosed with esophageal atresia between 2015 and 2019 were identified in the National Clinical Database. Postoperative anastomotic leakage was compared among patients to identify the potential risk factors, using univariate analysis. Multivariable logistic regression analysis included sex, gestational age, thoracoscopic repair, staged repair, and procedure time as independent variables.
Results
We identified 667 patients, with an overall leakage incidence of 7.8% (n = 52). Anastomotic leakage was more likely in patients who underwent staged repairs than in those who did not (21.2% vs. 5.2%, respectively) and in patients with a procedure time > 3.5 h than in those with a procedure time < 3.5 h (12.6% vs. 3.0%, respectively; p < 0.001). Multivariable logistic regression analysis identified staged repair (odds ratio [OR] 4.89, 95% confidence interval [CI] 2.22–10.16, p < 0.001) and a longer procedure time (OR 4.65, 95% CI 2.38–9.95, p < 0.001) as risk factors associated with postoperative leakage.
Conclusion
Staged procedures and long operative times are associated with postoperative anastomotic leakage, suggesting that leakage is more likely after complex esophageal atresia repair and that such patients require refined treatment strategies.
