Dynamic Imaging Grade of Swallowing Toxicity in Children with Esophageal Atresia.

INTRODUCTION

The Dynamic Imaging Grade of Swallowing Toxicity (DIGEST) scale was developed to evaluate the safety, efficiency, and overall pharyngeal swallowing performance in patients with dysphagia (DIGESTs, DIGESTe, and DIGESTt, respectively). Although various types of swallowing dysfunction are encountered in children with esophageal atresia (EA), oropharyngeal dysphagia poses risk for aspiration. Therefore, a retrospective study was performed to evaluate the safety and efficacy of swallowing by using DIGEST score in children with EA.

PATIENTS AND

METHODS

Thirty-nine EA patients were included. The demographic features, respiratory problems, results, and outcomes of surgical treatment were evaluated from medical records. The videofluoroscopic swallowing evaluation investigated for both airway protection and bolus residuals at the level of vallecula, posterior pharyngeal wall, and pyriform sinus at liquid and pudding consistencies. The penetration and aspiration scale (PAS) was used to define penetration and aspiration severity, and DIGEST was used to evaluate DIGESTs, DIGESTe, and DIGESTt.

RESULTS

The median age of the patients were 13 months (7-39 months), and male-to-female ratio was 25:14. Sixty-seven percent of patients were type-C EA and 61% of them has associated anomalies; 38% of patients had aspiration (PAS = 6-8) in liquids and 10% in pudding consistency. Life-threatening/profound swallowing dysfunction in DIGESTe (DIGEST = 4) was seen in 13% (n = 5) of patients; 40% of EA patients showed severe problems in DIGESTt.

CONCLUSION

DIGEST is a valid and reliable tool to define the efficacy and safety of swallowing in children with EA.
