Women's Perception of Transgastric and Transvaginal Natural Orifice Transluminal Endoscopic Surgery (NOTES) - Impact of Medical Education, Stage of Life and Cross-Cultural Aspects

Introduction

Despite that NOTES produces at least matchable clinical long-term results when compared to laparoscopy, still a restraint within the medical community and among patients is evident. Consequently, it might be meaningful to evaluate factors of patient's NOTES perception to promote its acceptance. NOTES is still quite novel and questionnaires regarding its perception by the public is still lacking even so in the Middle East. Aim of our survey is to investigate the viewpoint of female healthcare staff on NOTES.

Materials and Methods

A total of 350 questionnaires along with written information about Minimally Invasive Surgery and NOTES were distributed among the female staff in a Tertiary-care Hospital in Abu Dhabi, 257 were returned completely anonymously and voluntarily and entered into a database with a response rate of 73%. We surveyed factors like religion, medical background, age as well as history of previous laparoscopy, endoscopy, birth and other aspects that may impact a woman's perception of both transgastric and transvaginal NOTES for cholecystectomy and ovariectomy, respectively.

Results

Univariate analyses revealed the majority of Muslim women to be more receptive to NOTES as a choice of surgical technique for cholecystectomy and for ovariectomy, respectively, when compared to Christians and Hindus. However, when compared to Muslims, Christian and Hindu groups had a larger share of medical professions. Women with a medical background would opt significantly less for NOTES. Among younger women, NOTES cholecystectomy was refused due to anxiety concerning future pregnancies and sexual dysfunction. Multinomial logistic regression analysis determined medical background and with independent predictive value for the overall choice of interventional technique (p<0.001). Marital status played a significant role only in the comparison of laparoscopy vs transgastric NOTES when performing cholecystectomy and ovariectomy (p<0.01).

Conclusion

In this first study emanating from the Middle East, medical education and partly life stage rather than cross-cultural differences seem to influence NOTES perception in women.

Robotic transvaginal natural orifice transluminal endoscopic surgery for bilateral salpingo oophorectomy

Objectives

The vaginal surgical approach has not become the standard of care, despite its advantages. The Hominis™ Surgical System is a humanoid shaped robot-assisted system that was designed specifically for robotic vaginal natural orifice transluminal endoscopic surgery (RvNOTES). We aimed to present our experience with the first RvNOTES bilateral salpingo-oophorectomy (BSO) performed by the Hominis system.

Study design

A two-center prospective study of BSO by RvNOTES in women with nonmalignant indications conducted between August and December 2018. Women older than 18 years were offered to participate. Exclusion criteria included a history of abdominal malignancy, pelvic or abdominal irradiation, Crohn's disease, pelvic inflammatory disease, severe infections in the lower abdomen, active diverticulitis, deep infiltrating recto-vaginal endometriosis, and an active vaginal infection. The primary outcome of the study was the rate of conversion to open or 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.

Results

Eight women aged 50–70 years with BMI of 19–30 kg/m² were recruited. All the procedures were completed successfully without conversions to open surgery. No intraoperative complications were observed. Median blood loss was 10 mL (range: 10−50). The median duration of the procedure was 45 min (range: 38−91), and decreased over the study period. Surgeons’ usability assessment was very favorable, with a median of 5 on a 1–5 scale. The median visual analog scale (VAS) score was 1 (range: 1–3).

Conclusions

This is the first documentation of a surgery performed via the vagina using robotic instrumentation developed for this purpose. The disruptive technology of RvNOTES, with its fast learning curve, will make gynecological surgeries accessible to more women.
