The esophagus is the most important anatomical landmark for en bloc resection of the lungs and trachea. From the diaphragm and thoracic inlet, the esophagus is the dissection plane, which is located just below the pericardium and trachea (A, B). The head vessels and superior mediastinal tissue on the right and the left side of the trachea need to be cut for en bloc resection of the lung and trachea (A).
