Abstract
Objective: Robot‐assisted surgery is a recognized treatment for pelvic‐organ prolapse. Many of the surgical subgroup outcomes for apical prolapse are reported together leading to a paucity of homogenous data. Design: Prospective observational cohort study (https://clinicaltrials.gov; identifier NCT01598467) assessing outcomes for homogeneous subgroups of robot‐assisted apical prolapse surgery. Setting: Two European tertiary referral hospitals. Population: Consecutive patients undergoing robot‐assisted sacrocolpopexy (RASC) and supracervical hysterectomy with sacrocervicopexy (RSHS). Methods: Anatomical cure (simplified Pelvic Organ Prolapse Quantification (sPOPQ) stage 1,), subjective cure (symptoms of bulge) and quality of life (Pelvic Floor Impact Questionnaire [PFIQ‐7]). Main Outcome measures: Primary outcome: anatomical and subjective cure. Secondary outcomes: surgical safety and intraoperative variables. Results: Total 305 patients included (RASC N=188, RSHS N=117). Twelve months follow‐up available for 144 (RASC 76.6%) and 109 (RSHS 93.2%). Anatomical success of the apical compartment occurred in 91% (RASC) and in 99% (RSHS). In all compartments, success percentages were 67% and 65% respectively. Most recurrences were anterior compartment (15.7% RASC [symptomatic 12.1%]; 22.9% RSHS [symptomatic 4.8%]). Symptoms of bulge improved from 97.4% to 17.4% (p<0.0005). PFIQ‐7 scores improved from 76.7 ± 62.3 to 13.5 ± 31.1 (p<0.0005). Duration of surgery increased significantly in RSHS (183.1 ± 38.2 versus 145.3 ± 29.8 [p<0.0005]). Intraoperative complications and conversion rates were low (RASC: 5.3% and 4.3%; RSHS: 0.0% and 0.0%). Four severe postoperative complications occurred after RASC (2.1%) and one after RSHS (1.6%). Conclusion: This is the largest reported prospective cohort study on robot‐assisted apical prolapse surgery. Both procedures are safe, with durable results.
