Robot-Assisted Sacrocolporectopexy for Multicompartment Prolapse of the Pelvic Floor: A Prospective Cohort Study Evaluating Functional and Sexual Outcome

BACKGROUND: Pelvic floor disorders are a major public health issue. For female genital prolapse, sacrocolpopexy is the gold standard. Laparoscopic ventral mesh rectopexy is a relatively new and promising technique correcting rectal prolapse. There is no literature combining the 2 robotically assisted techniques. OBJECTIVE: This study was designed to evaluate the safety, quality of life, and functional and sexual outcomes of robot-assisted sacrocolporectopexy for multicompartment prolapse of the pelvic floor. DESIGN: This was a prospective, observational cohort study. SETTINGS: The study was conducted in a tertiary care setting. PATIENTS: All sexually active patients undergoing robot-assisted sacrocolporectopexy at our institution between 2012 and 2014 were included. INTERVENTION: Robot-assisted sacrocolporectopexy was the study intervention. MAIN OUTCOME MEASURES: Preoperative and postoperative (12 months) questionnaires using the Urinary Distress Inventory, Pescatori Incontinence Scale, Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, and Pelvic Floor Impact Questionnaire were completed. In addition Wexner and Vaizey incontinence scores and the Wexner constipation score were recorded postoperatively. RESULTS: Fifty-one patients underwent robot-assisted sacrocolporectopexy (median follow-up, 12.5 months). The simplified Pelvic Organ Prolapse Quantification improved significantly (p < 0.0005) for all 4 of the anatomic landmarks. Both median fecal (preoperative and postoperative Pescatori 4 vs 3, p = 0.002) and urinary incontinence scores (Urinary Distress Inventory, 27.8 vs 22.2; p < 0.0005) improved significantly at 12 months. Postoperatively median Wexner (3) and Vaizey incontinence (6) and Wexner Constipation (7) scores were noted. A positive effect on sexual function (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire score 31.8 vs 35.9; p = 0.002) and quality of life for each compartment (p < 0.0005) was observed. One patient (2%) developed mesh erosion. No multicompartment recurrences were detected. LIMITATIONS: This was a observational study with a limited follow-up, no control group, and no preoperatively validated constipation score. CONCLUSIONS: Robot-assisted sacrocolporectopexy is a safe and effective technique for multicompartment prolapse in terms of functional outcome, quality of life, and sexual function.
