Comparison of the modified laparoscopic Vecchietti and Davydov colpoplasty techniques in Mayer-Rokitansky-Küster-Hauser syndrome: A long-term follow-up analysis.

Aims: To introduce and compare the modified laparoscopic Vecchietti and Davydov techniques for vaginoplasty in patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome. Moreover, the long-term treatment of vaginal agenesis was followed-up.

Methods: This comparative retrospective cohort study enrolled a total of 53 women with MRKH syndrome. The patients underwent surgical creation of a neovagina including 32 patients who underwent the modified laparoscopic Vecchietti technique, and 21 patients who underwent the modified laparoscopic Davydov technique from January 2009 to February 2019. The perioperative parameters, complications, anatomical, and functional outcomes of the two groups were compared. Patients' sexual functions were evaluated over a long-term follow-up using the female sexual function index (FSFI) and the revised female sexual distress scale (FSDS-R).

Results: The medians (25th-75th) of the surgery duration for modified Vecchietti procedures was 50.0 (40.0-59.0) minutes, comparing to 135.0 (117.5-162.5) min for Davydov procedures (p < 0.001). The intraoperative blood loss was 20 (7.5-20.0) mL versus 50.0 (50.0-100.0) mL using the modified Vecchietti and Davydov approaches (p < 0.001), respectively. In the 39 follow-up cases, the lengths of the neovagina of the patients for Vecchietti group versus Davydov group were 7.9 ± 1.0 cm versus 8.6 ± 1.2 cm at 6 months after the vaginoplasty and 8.3 ± 0.7 cm versus 8.5 ± 0.9 cm after 2 years. There was no statistical difference in the FSFI and FSDS-R scores between the two groups.

Conclusions: Both the modified Davydov and Vecchietti laparoscopic procedures successfully achieved optimal anatomic and functional outcomes in treatments of vaginal agenesis. The modified Vecchietti technique is relatively simpler than the modified Davydov technique.
