12.1 C The best exposure of the distal thoracic esophagus is through a left thoracotomy.

Anatomically, the upper and middle thoracic esophagus runs

along the right side of the aorta, but the distal esophagus swings anterior

and then to the left of the aorta to exit into the abdomen. The esophagus

is not accessible through a median sternotomy because it lies in the

posterior mediastinum with the heart lying anterior to it. A right thoracotomy

necessary for the repair of the perforation and to perform a myotomy.
