Double vision approach applied by two teams for retrosternal gastric conduit for gastric tube cancer.

Gastric tube cancer is classically treated with resection through a midline sternal incision. However, because of its invasiveness and limited reconstructive potential, transdiaphragmatic laparoscopic or thoracoscopic dissection of the gastric tube has been investigated. As resection from only the abdominal or thoracic cavity is difficult, we performed surgery with a thoracic surgeon approaching from the thoracic cavity and an abdominal surgeon simultaneously approaching from the cervical and abdominal regions. The gastric tube may be tightly adhered to the back of the sternum, cervicothoracic transition or thoracoabdominal transition. Dissection can be safely performed by operating from two directions simultaneously, the neck and chest or chest and abdomen, to successfully withdraw the gastric tube from the abdominal cavity. We performed this surgery in four cases. This collaborative operation provided a good surgical view and allowed for safe dissection of the gastric tube without requiring sternotomy.
