Congenital esophageal stenosis is a rarely seen entity and depending on the degree of severity, symptoms may start in the newborn period or in later months. Symptoms in the early period enable early diagnosis. However, as symptoms are similar to those of gastro-esophageal reflux a long period of time may be spent on the incorrect diagnosis of gastro-esophageal reflux followed by unnecessary treatment. There is no consensus on treatment approach. The case presented is of a 10-month-old male patient who was transferred to our clinic when the desired response was not obtained from the treatment of gastro-esophageal reflux which had been diagnosed. The patient was subsequently diagnosed with esophagus stenosis and successfully treated with the balloon and bougie dilatation method.
