A new operative technique for the resection of gastric tube cancer by means of lifting the anterior chest wall and videoscope-assisted surgery.

The prolonged survival of patients receiving surgery for esophageal cancer has led to an increased incidence of adenocarcinoma arising in the gastric tube used for reconstruction (gastric tube cancer). In patients with advanced gastric tube cancer, resection of the gastric tube should be considered, but currently available procedures are very invasive. In patients undergoing curative surgery for gastric tube cancer that has developed after reconstruction through the retrosternal route, the gastric tube is usually resected through a median sternotomy, followed by reconstruction with the colon. However, postoperative complications often occur and treatment outcomes remain poor. We developed a new surgical technique for gastric tube resection without performing a sternotomy in patients with gastric tube cancer who had previously undergone reconstruction through the retrosternal route. Our technique was used to treat two patients. Two Kirschner wires were passed subcutaneously through the anterior chest; the chest was lifted to extend the retrosternal space and secure an adequate surgical field. The stomach was separated from the surrounding tissue under videoscopic guidance. Total resection of the gastric tube was done. The retrosternal space was used to lift the jejunum. Roux-en-Y reconstruction was performed. Neither patient had suture line failure or surgical site infection. Their recovery was uneventful. Our surgical technique has several potential advantages including (i) reduced surgical stress; (ii) the ability to use the retrosternal space for reconstruction after gastric tube resection; and (iii) a reduced risk of serious infections such as osteomyelitis in patients with suture line failure. Our findings require confirmation by additional studies.
