Thoracoscopic esophagectomy with three-field lymphadenectomy for thoracic esophageal cancer in a patient with a double aortic arch: a report of a case

Background We encountered an esophageal cancer patient with a double aortic arch (DAA) who underwent radical thoracoscopic esophagectomy with three-field lymph node dissection. A DAA generally makes it difficult to perform upper mediastinal lymph node dissection via both sides of the thoracic cavity. Furthermore, most patients with a DAA have a superior right aortic arch and right-sided descending aorta, which hampers radical esophagectomy with a typical right thoracic approach. We herein report our operative strategy of thoracoscopic esophagectomy via the left side of the thoracic cavity with a preceding cervical procedure.
