Background: Children undergoing surgical anastomosis for long-gap esophageal atresia (LGEA) often suffer from complications related to delayed oral feeding, which may impair their early development. Clinical swallow evaluation (CSE) is an effective technique to improve feeding outcomes. However, there are limited evidences on the application of CSE in these children.
Methods: Since 2020, serial CSEs have been consistently implemented for children undergoing anastomosis for LGEA in our hospital. We conducted a retrospective study comparing 19 children who received CSE with 31 historical controls who did not. Inverse probability of treatment weighting (IPTW) was applied to balance preoperative characteristics. We compared the time from surgery to full oral feeding and the rate of postoperative complications between the two groups. Growth curves for length-for-age Z score (LAZ) and weight-for-age Z score (WAZ) up to age 3 were fitted using generalized additive mixed models.
Results: The median time to full oral feeding was 1.1 months [interquartile range (IQR), 0.8-2.4] in the CSE group and 1.5 months (IQR, 0.6-5.7) for controls. After IPTW, CSE was associated with a shorter time to full oral feeding, with a weighted hazard ratio of 2.26 [95% confidence interval (CI), 1.21 to 4.24]. LAZ growth curves significantly differed between groups (P = 0.001).
Conclusion: CSE was associated with the expedited achievement of full oral feeding and a more favorable growth pattern before 3 years of age.
