Abstract
Introduction and hypothesis
Although an enlarged postoperative genital hiatus (GH) size has been identified as a predictor of recurrence following pelvic organ prolapse (POP) surgery, the protective role of concurrent level III support procedures to reduce the GH size at the time of minimally invasive sacrocolpopexy (MI-SCP) remains unclear. The objective of this study was to compare 24-month composite prolapse recurrence following MI-SCP between patients with a 6-month postoperative GH measurement of <3 cm versus ≥3 cm; and to explore the impact of concurrent level III support procedures on prolapse recurrence, bowel, and sexual function.
Methods
This was a secondary analysis of two randomized controlled trials of women who underwent MI-SCP from 2014 to 2020. Our primary outcome was composite prolapse recurrence defined as retreatment with either pessary or surgery, and/or subjective bothersome vaginal bulge. A receiver operating characteristic (ROC) curve was generated to identify a 6-month GH cutoff point associated with 24-month composite recurrence.
Results
Of the 108 women who met the inclusion criteria, 13 (12%) had composite prolapse recurrence at 24 months: 12 patients (11.1%) reported a bothersome vaginal bulge, and 3 patients (2.8%) underwent retreatment with surgery. A ROC curve demonstrated that a 6-month postoperative GH size of 3 cm had 84.6% sensitivity to predict vaginal bulge and/or retreatment at 24 months (area under curve = 0.52). There was no difference in the composite prolapse recurrence between the groups; however, only patients with a 6-month GH >3 cm underwent retreatment.
Conclusions
Twenty-four-month composite prolapse recurrence does not differ based on 6-month GH size; however, surgical failure may be more common in those with a GH size greater than 3 cm.
