Study Objective:
The Hominis surgical system is a novel robot-assisted system, designed specifically for robotic vaginal natural orifice transluminal endoscopic surgery (RvNOTES). We presented our experience of the first 30 RvNOTES hysterectomies assessing the feasibility and safety of this technology.
Design:
A two-center prospective study.
Setting:
Academic tertiary referral centers. The ethics committees approved the study in both centers.
Patients:
Thirty women with benign indication for hysterectomy.
Intervention:
RvNOTES hysterectomy performed by the Hominis surgical system.
Measurements And Main Results:
The primary outcome of the study was the rate of conversion to open or conventional laparoscopic approaches. Secondary outcomes included intra- and postoperative adverse events, operative time, estimated blood loss, length of hospital stay, and 6-week follow-up assessment. A total of 15 women were enrolled at each site. The median age was 59 years (range: 37-79) and the median body mass index was 25.4 kg/m2 (range: 17.6-40.0). Twenty-four women (80%) had comorbidities. All the procedures were completed successfully without conversion to open abdominal, traditional vaginal, or conventional laparoscopic surgery. No intraoperative complications were observed. Median blood loss and procedure duration were 50 mL (range: 20-400) and 57 minutes (range: 24-88), respectively. Postoperative pain was minimal, with a median visual analog scale of 3 (range: 1-5) for the first 24 hours following surgery. The median hospital stay was 3 days (range: 2-8). According to the treating physicians' evaluations, the vaginal cuff was fully healed in all patients at the 6-week postoperative follow-up visit.
Conclusions:
This is the first publication of robot-assisted vaginal hysterectomy using the Hominis surgical system. The positive results of this study show this new technology to be a safe and effective tool for vaginal natural orifice transluminal endoscopic surgery, enabling surgeons to operate vaginally with the known advantages of robotic modality.
