Robotic transvaginal natural orifice transluminal endoscopic surgery for bilateral salpingo oophorectomy

Enabling Technologies for Gynecologic Vaginal Surgery: A Systematic Review

OBJECTIVE

To systematically review the literature to evaluate clinical and surgical outcomes for technologies that facilitate vaginal surgical procedures.

DATA SOURCES

We systematically searched MEDLINE, EMBASE, and ClinicalTrials.gov from January 1990 to May 2022.

METHODS OF STUDY SELECTION

Comparative and single-arm studies with data on contemporary tools or technologies facilitating intraoperative performance of vaginal gynecologic surgical procedures for benign indications were included. Citations were independently double screened, and eligible full-text articles were extracted by two reviewers. Data collected included study characteristics, technology, patient demographics, and intraoperative and postoperative outcomes. Risk of bias for comparative studies was assessed using established methods, and restricted maximum likelihood model meta-analyses were conducted as indicated.

TABULATION, INTEGRATION, AND RESULTS

The search yielded 8,658 abstracts, with 116 eligible studies that evaluated pedicle sealing devices (n=32), nonrobotic and robotic vaginal natural orifice transluminal endoscopic surgery (n=64), suture capture devices (n=17), loop ligatures (n=2), and table-mounted telescopic cameras (n=1). Based on 19 comparative studies, pedicle sealing devices lowered vaginal hysterectomy operative time by 15.9 minutes (95% CI, -23.3 to -85), blood loss by 36.9 mL (95% CI, -56.9 to -17.0), hospital stay by 0.2 days (95% CI, -0.4 to -0.1), and visual analog scale pain scores by 1.4 points on a subjective 10-point scale (95% CI, -1.7 to -1.1). Three nonrandomized comparative studies and 53 single-arm studies supported the feasibility of nonrobotic vaginal natural orifice transluminal endoscopic surgery for hysterectomy, adnexal surgery, pelvic reconstruction, and myomectomy. Data were limited for robotic vaginal natural orifice transluminal endoscopic surgery, suture capture devices, loop ligatures, and table-mounted cameras due to few studies or study heterogeneity.

CONCLUSION

Pedicle sealing devices lower operative time and blood loss for vaginal hysterectomy, with modest reductions in hospital stay and pain scores. Although other technologies identified in the literature may have potential to facilitate vaginal surgical procedures and improve outcomes, additional comparative effectiveness research is needed.

Clinical applications of robotic surgery platforms: a comprehensive review

Robotic surgery has expanded globally across various medical specialties since its inception more than 20 years ago. Accompanying this expansion were significant technological improvements, providing tremendous benefits to patients and allowing the surgeon to perform with more precision and accuracy. This review lists some of the different types of platforms available for use in various clinical applications. We performed a literature review of PubMed and Web of Science databases in May 2023, searching for all available articles describing surgical robotic platforms from January 2000 (the year of the first approved surgical robot, da Vinci® System, by Intuitive Surgical) until May 1st, 2023. All retrieved robotic platforms were then divided according to their clinical application into four distinct groups: soft tissue robotic platforms, orthopedic robotic platforms, neurosurgery and spine platforms, and endoluminal robotic platforms. Robotic surgical technology has undergone a rapid expansion over the last few years. Currently, multiple robotic platforms with specialty-specific applications are entering the market. Many of the fields of surgery are now embracing robotic surgical technology. We review some of the most important systems in clinical practice at this time.

Vaginal Natural Orifice Transluminal Endoscopic Surgery Revolution: The Next Frontier in Gynecologic Minimally Invasive Surgery

Despite guidelines that assert that the vaginal route for benign hysterectomy is preferred as the most minimally invasive approach, rates of vaginal hysterectomy remain very low in the United States. Vaginal natural orifice transluminal endoscopic surgery (vNOTES) might reverse the trend. Potential advantages of vNOTES compared to traditional laparoscopic and robotic approaches include the potential for less pain, decreased operative time, improved cosmesis, and decreased risks. Importantly, vNOTES might allow for the conversion of laparoscopic and robotic routes back to vaginal due to surgeon factors.

Integration of a Robotic Platform for Sacrocolpopexy in Transvaginal Natural Orifice Transluminal Endoscopic Surgery: A Novel Surgical Technique

OBJECTIVE

To demonstrate the feasibility and the simplified surgical techniques of intraabdominal suturing and knot-tying in robotic transvaginal natural orifice transluminal endoscopic surgery (RV-NOTES) sacrocolpopexy.

MATERIALS AND METHODS

We report on two patients with symptomatic stage II apical pelvic organ prolapse who underwent a new technique of RV-NOTES sacrocolpopexy. Case one: A 69-year-old G2P2002 with a history of two prior vaginal deliveries presented with a vaginal bulge and pressure symptoms. She was initially fitted for a pessary but was unsatisfied and elected to proceed with surgical intervention. Case two: A 50-year-old G2P0011 female with a history of one prior vacuum-assisted vaginal delivery presented with symptoms of vaginal mass and bleeding due to an endometrial polyp. She was noted to have stage 2 apical prolapse and opted for transvaginal sacrocolpopexy.

RESULTS

Both patients were observed overnight and discharged home twelve hours after surgery on postoperative day 1, after completing a voiding trial. For both patients, the postoperative course was unremarkable, and they only required one day of pain medications. At the three-week follow-up visit, they endorsed no postoperative pain or complications, and the POP-Q stage was noted to be 0. Patients had telemedicine visits at eight weeks postoperatively, at which time they had returned to their regular activities and denied symptoms of vaginal bulge or pressure.

CONCLUSION

Robotic assisted transvaginal NOTES sacrocolpopexy is a feasible and an alternative to traditional laparoscopic NOTES sacrocolpopexy.

Robotic Vaginal Natural Orifice Transluminal Endoscopic Hysterectomy for Benign Indications

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.
