Functional and sexual outcomes following surgical vaginal introital reduction

Abstract

Objective: Surgical introital reduction procedures are commonly performed for the treatment of vaginal laxity (VL), yet poorly studied. The aim of this study was to assess clinical outcomes following surgical vaginal introital reduction for VL.

Methods: This was an ambidirectional cohort study conducted in a single urogynecology center. All sexually active women who had vaginal introital surgical reduction for VL between March 2015 and September 2020 were included in this study. VL was defined as a genital hiatus distance ≥4cm according to the POP-Q classification, associated with symptoms of laxity. The primary endpoint was sexual health assessed by the Pelvi-Perineal Surgery Sexuality Questionnaire (PPSSQ), while the secondary endpoints included postoperative pain, perioperative complications, rate of dyspareunia, patient satisfaction and success rate based on the Patient Global Improvement Index (PGI-I) and Vaginal Laxity Questionnaire (VLQ).

Results: Of the 27 patients sent the questionnaires, 23 sexually active patients returned the completed ones and were included in the study. Participants had a mean age and BMI of 41 years (range 24-74) and 21.3 (range 17.6-31.9) respectively. The most prevalent preoperative symptom was feeling of VL in 82.6% followed by bulging sensation in 47.8%. Preoperative dyspareunia was reported in 8/23 (34.8%). Surgical interventions involved perineorrhaphy with (n=14) or without (n=9) levator ani plication. The PPSSQ mean sexual health score was 86.7/100 (SD 5.8; range 16.7-93.3) and the mean discomfort and pain score was 27.5/100 (SD 26.0; range 0-80). Postoperative sexuality was reported to better, identical or worse in 16 (69.6%), 2 (8.7%) and 5 (21.7%) patients respectively. On PGI-I, patients reported feeling much better, better, slightly better and no change in 10 (43.5%), 5 (21.7%), 5 (21.7%) and 3 (13.0%) respectively. None of the women reported feeling worse. The overall post-operative complication rate was 3/23 (13.0%), including a perineal hematoma, and two cases of reoperation for narrow introitus. De novo dyspareunia was reported by 11/18 (61.1%) patients, occurring often or more in 4/18 (22.2%) patients, due to narrow introitus (n=2), enlarge introitus (n=1) and vaginal dryness (n=1).

Conclusion: Vaginal introital reduction surgery is a viable treatment option for symptoms of vaginal laxity after failure of conservative measures. However, patients should be made aware of the risk of de novo dyspareunia.
