Abstract

Abstract: Introduction: Levator ani muscle avulsions potentially increase recurrence after anterior colporrhaphies. We aimed at evaluating the impact of avulsions on anatomical and patient‐reported outcomes 1 year after the Manchester procedure for primary anterior compartment pelvic organ prolapse. Material and methods: Prospective cohort study of 189 women undergoing the Manchester procedure between October 2014 and January 2017. Avulsions were diagnosed by transperineal ultrasound. Women with and without avulsions were compared for 1‐year postoperative outcomes; Pelvic Organ Prolapse Quantification measurements, subjective satisfaction (1—worse to 4—cured), failure (new prolapse treatment), response to validated questionnaires on pelvic floor distress and sexual function, and a composite outcome (subjectively cured and optimal anterior compartment outcome (stage 0‐I)). Optimal mid‐compartment outcome was defined as cervix ≥5 cm above the hymen. Factors potentially associated with poor anatomical outcomes (anterior compartment stage ≥II) or pelvic floor distress were analyzed using regression analyses. Results: Fewer women with avulsions (present in 50.8%) obtained optimal mid‐compartment outcomes (88.2% vs 77.1%; P = 0.05). The groups were otherwise similar in terms of mid‐compartment reduction, anterior compartment results, failure rate, subjective satisfaction, pelvic floor/sexual symptoms, and combined optimal subjective and anatomical outcome. Only preoperative anterior compartment stage ≥III was associated with poor anatomical outcome ( P < 0.01). A high preoperative symptom score was associated with a high postoperative symptom score ( P < 0.001). Conclusions: Although fewer women with avulsions obtained optimal mid‐compartment results, avulsions had no impact on other anatomical or symptomatic outcomes 1 year after the Manchester procedure for primary anterior compartment prolapse.
