VNOTES Hysterectomy: What about Obese Patients?

Abstract

To compare the surgical outcomes of hysterectomy by vaginal natural orifice transluminal endoscopic surgery (vNOTES) for patients with body mass index (BMI) <30 and BMI ≥30. A retrospective cohort study. A French teaching hospital. All patients who underwent a vNOTES hysterectomy from February 2020 to January 2022 were included (N=200). The vNOTES approach was chosen for all patients requiring a hysterectomy, unless the procedure was for endometriosis or cancer (except grade 1 endometrioid adenocarcinoma). Patients were categorized into 2 groups based on their BMI (<30 or ≥30 kg/m2). The population characteristics, surgical outcomes, and hospitalization outcomes were compared. The main outcome was the intraoperative conversion rate. Secondary end points were blood loss, operative time, perioperative and postoperative complications, and same-day surgery management. A total of 146 patients were included in the BMI <30 group, and 54 patients in the BMI ≥30 group. There was no statistical difference between obese and nonobese patients concerning intraoperative conversion (p=.150), with 4 cases occurring in the BMI <30 group (2.74%) and 4 occurring in the BMI ≥30 group (7.41%). Operative times were longer in obese patients (115.93 min [±55.28] vs 79.78 min [±40.38], p <.001). There was no significant difference in blood loss (p=.337) or perioperative and postoperative complications (p=.346 and p=.612, respectively). The ability to complete the surgery as a same-day procedure was no different between obese and nonobese patients (p=.150). The results concerning intraoperative conversion and perioperative and postoperative complications show that vNOTES hysterectomies seem to be feasible for obese patients. When same-day surgery was decided before surgery, no more obese than nonobese patients were converted to conventional hospitalization. Further studies are needed to confirm these observations.
