Abstract
in English, Turkish

Congenital esophageal stenosis (CES) is a rare congenital disorder which may be isolated or associated with esophageal atresia (EA). It courses with esophageal outflow tract obstruction. Esophageal epiphrenic diverticulae are esophageal outpouchings above diaphragm which develop because of an underlying esophageal motor disorder. We present an infant who had CES associated with EA detected during the course of routine follow-up. She underwent several sessions of esophageal balloon dilatations for CES with some symptomatic improvement. However, an epiphrenic diverticulum (ED) developed during the course of treatment which was detected by further investigations. A surgical excision was performed with a successful outcome. An ED developed secondary to CES has not been previously reported. We have highlighted the diagnostic modalities employed, treatment options, and clinical follow-up for these two rare conditions in children.

Doğumsal özofagus darlığı (DED) tek başına görülen veya özofagus atrezisine (ÖA) eşlik eden nadir bir doğumsal hastalıktır. DED özofagus boşalmasında tıkanıklık ile seyreder. Özofagusun epifirenik divertikülleri (ED) ise diyafram üstü seviyede oluşan özofagus çıkıntılarıdır. Altta yatan özofagus motor hastalıkları zemininde gelişirler. ÖA ameliyatı sonrasına rutin takip sırasında DED tanısı konan bir hasta sunulmuştur. Hastaya DED tedavisi amacıyla çeşitli kereler balon dilatasyon uygulanmış ve semptomlarında kısmi düzelme sağlanmıştır. Bu tedavi esnasında yapılan ileri tetkiklerle hastada ED geliştiği tespit edilmiştir. Cerrahi rezeksiyon ile başarılı sonuç elde edilmiştir. DED nedeniyle gelişen ED daha önce bildirilmemiştir. Bu iki nadir duruma ilişkin uygulanan tanısal yöntemler, tedavi seçenekleri ve klinik izlem bulguları vurgulanmıştır.
