vNOTES (vaginal natural orifice transluminal surgery) gynecologic procedures in morbidly and super-morbidly obese women: five year experience

Purpose To analyze our experience with vNOTES gynecologic procedures in women with morbid and super morbid obesity to determine feasibility and compare outcomes with standard minimally invasive techniques. Methods Gynecologic procedures performed by three surgeons on women with a body mass index (BMI) >= 40 kg/m(2) from 2017 to 2023. A subset of women with a BMI >= 5 0 kg/m(2) was also analyzed. Results 103 women with a BMI >= 40 kg/m(2) were identified (Class IV), 19 of whom had a BMI >= 50 kg/m(2) (Class V). For the entire population the mean BMI was 45.7 kg/m(2) (40-62). 29 women were nulliparous and 23 had at least one prior cesarean delivery. 51 had no prior abdominal surgery. The procedures performed were hysterectomy and removal of adnexae in 77 patients, hysterectomy alone in six, adnexal surgery alone in nine, and hysterectomy with adnexectomy and lymph nodes in five. Two surgeries were converted to laparoscopy and five to laparotomy. Average surgical time was 87 min (30-232). Average blood loss was 82 mL (10-400). Mean uterine weight was 206 g (29-2890). 53 procedures were performed as outpatient, 44 had overnight observation, four had a length of stay of 2 days, one each for 4 days and 5 days. The laparoscopies occurred in one patient with an obliterated cul-de-sac and in one patient for lymph node removal. The laparotomies occurred for adnexal adhesions in one, bleeding in two, a cystotomy in one requiring urology consultation, and an obliterated cul-de-sac One patient developed a postoperative vaginal cuff hematoma not requiring intervention. Conclusionv NOTES gynecologic procedures are feasible in this high-risk population and may result in shorter recovery times and fewer complications than standard laparoscopy or transvaginal surgery. What does this study add to the clinical work: VNOTES approach is feasible in morbidly obese women and may have distinct advantages over conventional laparoscopic, vaginal or open techniques.
