Robot-assisted Fallopian tube transection and anastomosis using the new REVO-I robotic surgical system: feasibility in a chronic porcine model.
To evaluate the feasibility and safety of the new REVO-I robotic platform by performing Fallopian tube transection and anastomosis in live porcine models.



A prospective chronic animal study was carried out in four crossbred female pigs. The primary outcome was assessment of the pigs' 2-week survival. The secondary outcomes were measurements of intra-operative variables and the complications or difficulties arising when using the REVO-I.



Fallopian tube anastomosis was successfully performed in four porcine models. The mean (range) operating time was 66 (46-104 min), docking time 22.25 (14-53) min and console time 18 (13-20) min. The REVO-I robotic system functioned appropriately, with no technical problems or difficulties noted during the procedures. Both the surgeon and the bedside assistants reported ease of use and better performance with subsequent procedures. All pigs were alive 2 weeks after surgery, with no peri-operative complications related to the use of the robot.



This preclinical chronic porcine study showed that the REVO-I robotic surgical system is a feasible and safe robotic instrument that can be used by surgeons to perform skillful robotic procedures in porcine models. Our next objective will be to demonstrate its safety in humans.
