Background. Congenital esophageal stenosis (CES) occurs in 1/25-50 000 live births. It is a rare diagnosed and must be differentiated from gastroesophageal reflux disease (GERD). Case report. We present the case of a 10-months old female with vomiting and regurgitations since the first day of life. The patient was treated as having GERD. She was administered different infant formulas including elemental formulas. On three occasions she had imminent bronchial aspiration. The patient's weight was normal because she received a diluted diet and elemental formula until 10 months of age. Esophagogram and endoscopy confirmed CES diagnosis. Surgery was done after the second endoscopic dilatation failure. End-to-end anastomosis was done at 11 months. Histopathological findings reported fibromuscular type of CES. Conclusion. CES is a rare entity with a frequently delayed diagnosis. Patients are often treated according to diagnosis of GERD until intolerance to semisolid diet appears and CES is suspected. Esophagogram and esophageal endoscopy followed by balloon dilatation prior to end-to-end anastomosis is the treatment of choice.
