Secure Robotic Transthoracic Valvuloplastic Esophagogastrostomy by Double Flap Technique in Esophagogastric Junctional Cancer Surgery.

Valvuloplastic esophagogastrostomy by the double flap technique (VPEG-DFT) after proximal gastrectomy for early proximal gastric cancer or esophagogastric junctional cancer (EGJC) is a promising procedure to prevent reflux. However, the transhiatal procedure alone for alimentary reconstruction is sometimes too complex because of the short esophageal remnant. Therefore, additional transthoracic procedures are needed in some patients with EGJC. Although additional thoracoscopic surgery has been reported, no reports to date have described robotic transthoracic VPEG-DFT after excision of EGJC. We herein describe the secure robotic techniques of transthoracic VPEG-DFT performed in 3 patients with EGJC. After completion of the abdominal procedures by robotic and extracorporeal creation of H -shaped flaps on the gastric remnant, robotic VPEG-DFT through the right thoracic approach was performed in the prone position. To accomplish VPEG-DFT in the thorax of patients in the prone position, fixation of the esophagus and stomach was performed before the rotation of the 2 organs to expose the planned anastomotic aspect. In addition, the final abdominal phase was required again to prevent a postoperative hiatal hernia. Secure techniques of right transthoracic VPEG-DFT by robotic surgery could contribute to the successful treatment of EGJC when the remnant esophagus is too short.
