A novel single-port robotic proximal gastrectomy with right-sided overlap and single-flap valvuloplasty (RPG-ROSF) to treat gastroesophageal cancer: A case report.

ABSTRACT

Robotic surgery has been widely used in surgical gastric cancer treatments, including proximal gastrectomy. Single-port robotic system is gaining more popularity in robotic surgery, but there has been no report on its application in robotic proximal gastrectomy with right-sided overlap and single-flap valvuloplasty (RPG-ROSF). Here, we report an RPG-ROSF using a novel single-port robotic system in a 51-year-old male patient with an early-stage gastroesophageal cancer detected by gastroscopy. It took 90 min for robotic setup, 143 min for dissection, and 161 min for digestive tract reconstruction. There was no complication during and after the surgery. The patient was discharged in 8 days postsurgery. The pathological staging of the adenocarcinoma was pT1aN0M0. This preliminary study demonstrated the feasibility and safety of a novel single-port robot in RPG-ROSF.
