Dissection of thorax from a posterior approach
Thoracic viscera.
The esophagus has been divided at the lower border of the second thoracic vertebra and again just above the diaphragm. The intervening portion of the esophagus has been removed to expose the trachea and pericardium. The latter has been opened to the margins of the oblique sinus.
