ABSTRACT

Objective: To gain insight into the feasibility and safety of a novel vaginal robot for performing supracervical hysterectomy in an ovine model. Introduction: The clinical application of transvaginal natural or fice transluminal endoscopic surgery (vNOTES) has broadened significantly. vNOTES reduces wound complications such as infection, hematoma formation, or herniation and is currently utilized for hysterectomy, adnexal surgery, myomectomy, and staging surgery for endometrial cancer. Robotic assistance has been proposed to overcome the current vNOTES mechanical obstacles. The implementation of the current robots has limited utility due to their bulk and inflexibility. Robotic Natural Orifice Transluminal Surgery (rNOTES) is the new frontier in advancement of surgical robots. In developing new task specific robots, it is important to utilize an accurate model for testing. A novel vaginal robot introduced through the posterior cul-de-sac to perform a complete retrograde hysterectomy is the subject of this study. Methods: The study was conducted at the animal lab, Asaf-Harofe hospital, Israel. The ovine model was preferred since the anatomical landmarks and vascular anatomy are comparable to the human except for a bicornuate uterus in sheep. A vaginal robotic supra-cervical hysterectomy was performed in a sheep. Results: A vaginal robotic supracervical hysterectomy was performed successfully in an ovine model. The uterus was extracted via the entry point in the pouch of Douglas. 20 cc of blood loss was reported and no complications were observed. Conclusions: Vaginal supracervical hysterectomy via a vaginal approach using a novel robotic system was found to be feasible.
