Bilateral posterior Richter sacrospinous fixation with native tissue: anatomical and functional results and quality of life assessment over 10 years.

Abstract

Pelvic organ prolapse (POP) is a common condition that affects 50% of women who have given birth in their lifetime. With stop of vaginal mesh sale in 2019, the sacrospinous fixation technique according to Richter with native tissue has seen its incidence tripled in 15 years. Classically, sacrospinous fixation according to Richter is performed unilaterally, however its unilateral or bilateral character is controversial. Objective of this work is to evaluate the efficacy and safety of bilateral sacrospinous fixation according to Richter by the posterior approach with native tissue (SSB). We performed a retrospective single-center study. From March 12, 2010 to March 23, 2020, all first-time operated patients who underwent SSB in CHU Strasbourg gynecological surgery unit for symptomatic POP management were included. The main endpoint of our work is the anatomical and functional success rate at 12 and 24 months. The secondary judgment criteria of our work were based on the postoperative evaluation of patient's quality of life according to the PFDI-20 score as well as the rate of postoperative complications. 77 patients were included in our work. The anatomical success rate at 12 months is 94% and 81% at 24 months regardless of the compartment affected. The functional success rate is 94% at 12 months and 82% at 24 months. Quality of life evaluation through the PFDI-20 scale revealed a clear improvement in the symptomatology related to POP: 127/300 +/- 27.3. preoperatively and 59.8 ± 14.7 postoperatively. Bilateral sacrospinous fixation according to Richter by posterior approach with native tissue is a safe and effective surgical technique allowing a clear improvement in patients quality of life.
