[Tracheal Foreign Body Removal under Rigid Bronchoscope in a Child with Fistula-like Structure in the Trachea after Surgery of Congenital Esophageal Atresia.]

We report a case of 1-year-2-month old boy with tetralogy of Fallot who had a surgical history of Gross C-type of congenital esophagus atresia. Difficult ventila- tion occurred by aberrant placement of tracheal tube during previous general anesthesia. He suffered from a cyanosis four hours after dinner. Tracheal foreign body was suspected. General anesthe- sia was induced for an emergency foreign body re- moval under rigid bronchoscopy. After the insertion of a tracheal tube just below glottis, the stenosis and fistula-like structure were confirmed in the trachea by bronchofiberscopy. The tip of the tube was placed beyond them. A "natto" was found in the orifice of the left main bronchus, and taken out by a rigid bronchoscope. Although tracheal intubation was performed several times during procedure, aberrant placement of the tra- cheal tube could be avoided by using bronchofibers- copy. We have to consider the remaining anatomic abnormalities of the respiratory tract in children after surgery of congenital esophageal atresia.
