Medium-term outcomes after robotic-assisted lateral suspension with mesh for advanced multi-compartmental prolapse

Robotic abdominal lateral suspension (RALS) is an innovative mini-invasive surgical technique that allows treating apical and anterior prolapse. The safety and efficacy of this strategy have not yet been tested.

We completed a prospective case series of 115 RALS to treat apical and anterior prolapse stage III or IV, with no or minimal (stage I) posterior defect. Clinical evaluation was performed with a simplified POP quantification system (POP-Q). Mean follow-up was 28 ± 4 months. Primary outcomes were objective and subjective cure; secondary outcomes were reoperation rate for recurrence, erosion rate and complications. Objective cure was defined as POP-Q ≤ 1. Subjective cure was defined as absence of vaginal bulge. Patient's satisfaction was measured using the Patient Global Impression of Improvement Scale (PGI-I).

There was a significant improvement in POP-Q score in all treated compartments with an objective cure rate of 88.7% for the anterior and 93.1% for the apical compartment (p < 0.0001). Subjective cure rate was 82%. The emergence of de novo high rectoceles was not significant in the cohort, as much as the development of de novo stress or urge urinary incontinence. Reoperation rate for POP was 11.3% (8 recurrent cystoceles without apical descent and 5 apical and anterior relapses). No postoperative complications of Clavien-Dindo grade ≥ 3a were seen. Mesh exposure rate was 0.9%; 58.2% patients compiled a PGI-I score at 18-24 months post-surgery, reporting high satisfaction rates.

RALS is highly effective at a mid-term follow-up for the treatment of advanced apical and anterior POP.
