Esophageal atresia: gastroesophageal functional follow-up in 5-15 year old children.

PURPOSE

Esophageal atresia (EA) is one of the most frequent congenital alimentary tract anomalies with a considerable morbidity throughout childhood. This study evaluates the gastroesophageal problems in 5-15 year old children with EA and aims to identify factors predisposing to esophagitis in EA.

MATERIAL AND METHODS

Fifty-nine patients primarily operated at Odense University Hospital, Denmark, during 1993-2005 were included in this follow-up study. The patients underwent the following examinations: Interview, upper endoscopy, endoscopic ultrasonography, high-resolution esophageal manometry (HREM), and pH- and multichannel intraluminal impedance (MII) measurements. Twenty-five patients with suspected gastro-esophageal reflux disease (GERD) underwent the same investigations and served as controls.

RESULTS

Median age was 10.2 years (7.1-13.3). Thirty-three (55.9%) presented with GERD symptoms, 41 (69.5%) with dysphagia, and 33 (55.9%) with respiratory symptoms. Twenty-nine (49.2%) had endoscopic esophagitis, and 26 (44.1%) histological esophagitis. Median reflux index (RI) was 8.3 (4.8-14.9). In 32 (55.2%) RI was above 7. Ten percent had eosinophilic inflammation. HREM showed dysmotility in the esophagus in all EA patients, 83.3% had no propagating swallows. No predictive factors predisposing the development of endoscopic esophagitis were identified.

CONCLUSIONS

Gastroesophageal problems in children born with EA are common. Routine follow-up with endoscopy and pH-metry in EA patients is warranted.
