STUDY OBJECTIVE: To compare the perioperative outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) hysterectomies for different uterine weights and shapes.
DESIGN: Observational study.
SETTING: Swiss teaching hospital.
PATIENTS: Women who underwent vNOTES hysterectomy for benign conditions between May 2020 and July 2023 (N = 238). Patients were divided into 4 subgroups depending on uterus weight and shape. Uteri weighting <280 g were classified as type 0. Uteri weighting ≥280 g were categorized as type 1 (no vascular pedicle displacement), type 2 (cranial displacement of adnexal vascular pedicles), and type 3 (displacement of uterine arteries).
INTERVENTIONS: All women underwent vNOTES hysterectomies. We compared perioperative outcomes for the 4 subgroups.
MEASUREMENT AND MAIN RESULTS: We classified 168 patients (70.6%) as uterus type 0, 33 patients (13.9%) as type 1, 24 patients (10.1%) as type 2, and 13 patients (5.4%) as type 3. Mean uterine weight was 135.8 ± 59.5 g in type 0, 398.0 ± 167.3 g in type 1, 603.5 ± 217.9 g in type 2, and 661.7 ± 281.6 g in type 3. Operative time in type 0 (65.1 ± 30.9 minutes) and type 1 (65.1 ± 24.0 minutes) was shorter than in type 2 (102.3 ± 60.0 minutes) and type 3 (115.2 ± 40.3 minutes). Blood losses were more significant in type 2 (158.5 ± 212.0 mL) and type 3 (158.5 ± 110.7 mL) than in type 0 (85.6 ± 113.5 mL). No difference in the rate of total complications among groups was observed (8.3%, 3.0%, 12.5%, and 15.4% in types 0, 1, 2, and 3, respectively).
CONCLUSION: The displacement of the vascular pedicles seems associated with longer operative time and more blood loss and could represent a marker for technical difficulty in vNOTES hysterectomy. However, it does not influence the perioperative complication rate.
