Successful bronchotracheal reconstruction in esophageal bronchus: two case reports.

Esophageal bronchus is the most common congenital bronchopulmonary foregut malformation. Current surgical treatment is resection of anomalous pulmonary tissue, which is often hypoplastic and destroyed by infection. The authors report two cases of bronchotracheal reconstruction. The diagnosis was early, before 15 days of age. The anomalous pulmonary tissue had a pulmonary arterial supply and venous drainage as assessed by angiography and a good functional capacity on selective ventilation. Bronchotracheal anastomosis was successful in both cases: a right main bronchus at 25 days of age and a left main bronchus at 13 days of age. One child underwent reoperation 1 year later for bronchomalacia of the reimplanted bronchus. Both children are well with normal growth 3 and 7 years after surgery. Chest roentgenograms showed normal and symmetrical lung aeration. Tracheal reimplantation may be preferred to pulmonary resection when the anomalous pulmonary tissue is not destroyed. The pulmonary functional capacity is increased and the complications of pneumonectomy avoided.
