Three-dimensional vs two-dimensional endoscopic approach in urogynecology : a retrospective cohort study of laparoscopic sacrocolpopexy

Abstract

Aim: The gold standard to treat an apical pelvic organ prolapse is the abdominal route via a sacrocolpopexy, which is also reproduced by laparoscopic route. A laparoscopic sacrocolpopexy however, requires surgical expertise. Three-dimensional (3D) laparoscopy has been developed to overcome the lack of depth perception, that is a known disadvantage of conventional two-dimensional (2D) laparoscopy. This procedure can accelerate the learning curve and optimize the intra-, peri-, and postoperative outcomes. This study aims to compare 3D laparoscopy to traditional 2D laparoscopy for sacrocolpopexy. Methods: Data from 132 patients who underwent a sacrocolpopexy with 2D or 3D laparoscopy in Department of Obstetrics and Gynecology, University Medical Center of the Johannes Gutenberg University, between June 2012 and September 2021, were collected retrospectively. Seventy-one laparoscopic sacrocolpopexy operations in 2D (n = 23) and 3D (n = 48) group were reviewed and compared regarding the duration of surgery, blood loss and the length of hospital admission as primary objectives. Results: There were no differences in the baseline demographics between the two groups. The estimated blood loss (1.0 (±0.6) g/dL vs 1.7 (±1.0) g/dL, p = 0.010), and duration of surgery (115.4 (±34.7) min. vs 134.7 (±26.2) min., p = 0.012) was significantly better in favor of 3D laparoscopy. The length of hospital stay was comparable in both groups (p = 0.833). Furthermore, no differences were observed between the groups regarding other surgical outcomes. Conclusion: 3D laparoscopy shows a significant benefit in terms of estimated blood loss and surgery duration among complex urogynecological surgeries compared to traditional 2D laparoscopy.
