Abstract
We herein describe a single-port mediastinoscopic method for upper mediastinal dissection in esophageal cancer surgery. After the left cervical incision and lymphadenectomy, a Lap-Protector (Hakko, Tokyo, Japan) was inserted into the wound and an EZ Access port (Hakko) was attached. Esophageal mobilization with en bloc lymphadenectomy along the left recurrent laryngeal nerve was then performed using a port-in-port technique with conventional flexible laparoscopy. Carbon dioxide insufflation expanded the intramediastinal space, and minute structures in the deep mediastinum around the aortic arch, such as nerves, bronchial arteries, and lymphatic vessels, were clearly visualized, allowing lymphadenectomy to be safely and carefully performed along the nerve.
