Early Esophagogram and Esophagoscopy: Evaluating Anastomotic Integrity in Successfully Treated Type 3 Esophageal Atresia Survivors

Anastomotic narrowing post-Type 3 esophageal atresia (EA) primary repair has been linked to life-threatening respiratory complications and failure to thrive during infancy. It becomes important to find some method to ensure anastomotic adequacy in these patients. We in the study here aimed to find the role of follow-up esophagogram and esophagoscopy in detecting anastomotic stricture (AS) in the early stage and to find whether these help in reducing the morbidity in these patients.

Neonates with EA Type 3, who were successfully managed with primary anastomosis were prospectively enrolled and followed up in the study. Irrespective of symptoms, contrast esophagography and esophagoscopy were performed at the age of 2-4 months. Those with AS on endoscopy were followed for the need of dilatations required, respiratory complications, and failure to thrive if any.

Out of 64 patients, 32 patients could be followed up till the completion of the study. An esophagogram conducted at 2 months of age revealed significant dye retention in 10 patients, esophageal narrowing in two patients, and normal results in the remaining 18 patients. Endoscopy confirmed AS in 11 out of 32 (34.4%). Preendoscopy, 44% of patients exhibited respiratory morbidity. After endoscopic dilation, none of the patients developed pneumonia requiring admission. Failure to thrive was noted in 9% of the cases.

The use of esophagograms and endoscopies during the healing phase of anastomosis not only aids in the detection of ASs during its formation but also eases the process of their management.
