Assessing Feasibility and Outcomes of Robotic Single Port Transvaginal NOTES(RSP-vNOTES) Hysterectomy: A Case Series.

ABSTRACT

OBJECTIVE: To demonstrate the feasibility and short-term outcomes of Robot-Assisted Single Port vaginal NOTES (RSP-vNOTES) for total hysterectomy, with or without endometriosis resection for all stages. DESIGN: Retrospective case series. SETTING: Single academic tertiary care hospital in Houston, Texas, USA. PARTICIPANTS: 28 adult women with chronic pelvic pain who underwent RSP-vNOTES hysterectomy, with or without endometriosis resection. INTERVENTIONS: Hysterectomy with or without excision of endometriosis via single-port robot-assisted vNOTES platform (Intuitive Da Vinci SP Platform). MAIN RESULTS: 28 patients with a mean age of 40.1 years (range 24.0-54.0 years), mean BMI 28.5 kg/m2 (range 19.5-48.4 kg/m2), underwent RSP-vNOTES from November 11, 2023 to May 7, 2024. Five (17.9%) patients underwent solely a hysterectomy, while 23 (82.1%) patients underwent additional endometriosis resection; 28.6% with stage I, 25.0% stage II, 7.1% stage III, and 21.4% with stage IV. Mean total operative time was 188.7 minutes (range 135.0-427.0 minutes), with robot dock time of 2.9 minutes (range 1.0-10.0 minutes), robot console time of 97.3 minutes (range 51.0-221.0 minutes), and hysterectomy time of 55.3 minutes (range 24.0-170.0 minutes). Estimated blood loss averaged 32.1 mL (range 25.0-50.0mL). One case required a mini-laparotomy as the irregularly-shaped 1668g fibroid uterus was unable to be removed vaginally. Complications included one case of vaginal cuff cellulitis and one case of urinary tract infection. CONCLUSION: Our findings indicate that RSP-vNOTES, a novel single-port surgical approach, presents a promising alternative surgical platform in vaginal surgeries.
