The patient is a term male newborn with esophageal atresia and distal tracheoesophageal fistula.
Host summary
Patient positioning is left lateral decubitus with the arm extended and restrained, with a roll under the left axilla.
Host summary
Division of the azygous vein typically leads the surgeon to the fistula site.
Host summary
The azygous vein can be divided with an energy device, simply coagulated, or double clipped and divided.
Host summary
Thoracoscopic magnification allows for excellent delineation of the trachea and esophagus.
Host summary
The fistula is ligated with a suture ligature flush with the trachea but not divided initially to prevent the distal esophagus from retracting.
Host summary
Asking the anesthesiologist to push on the nasoesophageal tube aids in dissection of the proximal esophageal stump.
Host summary
The esophagus is often quite adherent to the trachea and may even share a common wall, requiring careful dissection.
Host summary
Dissection can be continued to the thoracic inlet, resulting in excellent mobilization of the proximal esophagus.
Host summary
The fistula is divided a few millimeters distal to the ligature to liberate the distal esophagus.
Host summary
Following fistula division, the ligature should be tested with 25 to 30 centimeters water positive pressure ventilation.
Host summary
The back wall anastomosis is completed first using interrupted 4-0 or 5-0 absorbable sutures.
Host summary
Extracorporeal knot tying was used in this case because the two ends came together nicely with minimal tension.
Host summary
Sutures are placed 2 to 3 millimeters apart, with 5 to 6 sutures usually sufficient to complete the posterior wall anastomosis.
Host summary
The nasoesophageal tube is advanced to protect the posterior wall prior to starting the anterior wall anastomosis.
Host summary
It is important to take full thickness bites of healthy esophageal wall and mucosa with each suture.
Host summary
Fewer sutures are usually required for the anterior wall anastomosis compared to the posterior wall.
Host summary
A chest tube was placed in this case, but this is no longer routinely used.
