Robotic single‐incision transabdominal and transvaginal surgery: initial experience with intersecting robotic arms

Abstract

BACKGROUND: Single-incision laparoscopic and natural orifice translumenal endoscopic surgery (NOTES) are technically challenging methods. Robotics might have the potential to overcome such hurdles with computer technology. METHODS: The da Vinci Standard and S System (Intuitive, Sunnyvale, USA) were used in human cadavers and pigs to perform single-incision transabdominal and transvaginal surgery. Robotic arms were crossed and control-switched to achieve intuitive control. RESULTS: It was possible to perform robotic single-incision laparoscopy in the typical, intuitive fashion. Transvaginal set-up, including docking of the system and introduction of instruments into the abdominal cavity, was possible but no useful manipulation could be performed. CONCLUSIONS: While robotic NOTES with the da Vinci surgical system was not successful, robotic single-incision surgery is feasible using the above set-up. This new approach seems to offer the advantages of single-incision surgery while maintaining the intuitive control of robotic surgery. Clinical application appears justified.
