Abstract

Background: Technological advances in visual systems have contributed to overcoming the limitations in spatial perception of minimally invasive techniques. To date, there is a lack of literature on the advantages of 3D vision systems over 4K in laparoscopic surgery, although benefits have been observed in the training setting.

Objectives: To compare operating times, perioperative outcomes, and task achievement using 3D and 4K vision systems for vaginal cuff closure performed by residents during total laparoscopic hysterectomy (TLH). All surgeons in training have obtained the Gynaecological Endoscopic Surgical Education and Assessment (GESEA) certificate.

Materials and methods: This is a prospective randomised trial (NCT04637022). Women undergoing total hysterectomies for benign conditions between January 2021 and November 2023 were enrolled in the study. Vaginal cuff closures were performed by surgeons in training who had obtained the second level of the GESEA programme certificate.

Results: Fifty-four patients were enrolled. There were no statistically significant differences in time between 3D and 4K vision for vaginal cuff closure (p=0.918). No statistically significant differences were observed for mean estimated blood loss (EBL) (overall: 62.85 ± 22.73mL; 3D: 65 ± 24.83mL; 4K: 61.11 ± 21.18; p=0.556) and median hospital stay (p=0.234). Three non-severe intraoperative complications in the 3D group (p=0.048) and three postoperative complications in the entire cohort (p=0.685) were reported.

Conclusions: The operating time for vaginal cuff closure performed by trainee surgeons is similar when comparing 3D vision during conventional laparoscopy and 4K vision systems. The choice of surgical vision systems may be guided by a cost analysis and surgeon preferences.

What is new? Substantial evidence is lacking regarding the advantages of incorporating 3D vision into standard laparoscopy for gynaecological surgery. This research seeks to assess whether the 3D visual system can provide benefits as compared to 4K visualisation during laparoscopic vaginal cuff closure performed by surgeons in training within the GESEA 2 certification programme.
