Benefits of the thoracoscopic approach for short- or long-gap esophageal atresia.

OBJECTIVE

To evaluate the feasibility and results of thoracoscopy in various types of esophageal atresia (EA).

MATERIALS AND METHODS

From April 2001 to August 2002, 5 patients with EA were treated by thoracoscopy. Their mean gestational age was 38 weeks and mean birth weight was 2700 g. Two patients had short-gap atresia with tracheo-esophageal fistula (type III according to Ladd's classification). Three had long-gap atresia: 2 with low fistula to the carina (type IV) and 1 without fistula (type I). Patients were placed in a prone position with the right side elevated at 80 degrees . Four intrapleural ports were necessary. The fistula when present was dissected and sutured with intrathoracic knots and esophageal anastomosis performed in the same manner.

RESULTS

Positive airway pressure increased in all patients after insufflation but was kept in a safe range to prevent lung injury. An esophageal anastomosis was performed in 3 cases (2 short gaps and 1 long gap). Oral feeding started on day 6, and their mean length of hospital stay was 14 days. For one child with type IV EA, the anastomosis was impossible because of a long gap confirmed by an immediate thoracotomy. The ends were just approximated. A "spontaneous" fistula developed, and normal feeding was possible 2.5 months later. For the child with type I EA, the pouches could be only approximated at 2 months of age. A spontaneous fistula developed with a stenosis. A redo anastomosis by open surgery allowed for normal feeding.

CONCLUSION

The thoracoscopic repair of an esophageal atresia is a reasonable choice for experienced surgeons treating patients, including those with long gaps.
