Comparison of outcomes between pessary use and surgery for symptomatic pelvic organ prolapse: A prospective self-controlled study

Abstract

Purpose: We compared the degree of pelvic floor symptom improvement between pessary use and prolapse surgery. Materials and Methods: Pessary-naïve women who elected prolapse surgery were enrolled and used a pessary preoperatively (for ≥7 days and ≤30 days). Pelvic floor symptoms were assessed at baseline, after pessary use, and at 3 months postoperatively. The primary outcome was concordance in the degree of symptoms improvement between pessary use and surgery, as assessed by Patient Global Impression of Improvement (PGI-I). Secondary outcomes were related to prolapse specific symptoms on validated questionnaires (POPDI-6, PFIQ-7). The McNemar test was used for comparisons of discordant pairs for comparisons of the PGI-I ratings after pessary use and surgery. Results: Sixty-one participants were enrolled (March 2016 through April 2019) and 58 patients used a pessary. Mean±standard deviation age was 60.7±10.7 years; 24.1% had prior hysterectomy, and 13.8% had prior prolapse surgery. While both treatments demonstrated symptomatic improvement, concordance in the degree of overall improvement on the PGI-I score was poor (n=40); responses significantly favored more improvement postoperatively (p<0.001). Pessary use and surgery were associated with significant improvements in prolapse symptoms from baseline on POPDI-6 (both p<0.001) and POPIQ-7 (pessary, p=0.002; surgery, p<0.001). The degree of improvement was larger postoperatively compared to post-pessary use on POPDI-6 (p<0.001) and PFIQ-7 (p=0.004). Conclusions: Both pessary use and surgery significantly improved pelvic floor symptoms from baseline. However, concordance in degrees of improvement between these treatments was poor, with more favorable outcomes after surgery for prolapse symptoms.
