Laparoscopic sacrocolpopexy versus abdominal sacrocolpopexy for vaginal vault prolapse: long-term follow-up of a randomized controlled trial

Abstract

Abstract Introduction and hypothesis The objective of this study was to evaluate long-term outcomes of laparoscopic sacrocolpopexy (LSC) versus abdominal sacrocolpopexy (ASC) for vaginal vault prolapse (VVP). Methods Long-term follow-up of a multicenter randomized controlled trial (SALTO trial). A total of 74 women were randomly assigned to LSC (n=37) or ASC (n=37). Primary outcome was disease-specific quality of life, measured with validated questionnaires. Secondary outcomes included anatomical outcome, composite outcome of success, complications, and retreatment. Results We analyzed 22 patients in the LSC group and 19 patients in the ASC group for long-term follow-up, with a median follow-up of 109 months (9.1 years). Disease-specific quality of life did not differ after long-term follow-up with median scores of 0.0 (LSC: IQR 0–17; ASC: IQR 0–0) on the “genital prolapse” domain of the Urogenital Distress Inventory in both groups (p = 0.175). Anatomical outcomes were the same for both groups on all points of the POP-Q. The composite outcome of success for the apical compartment is 78.6% (n = 11) in the LSC group and 84.6% (n = 11) in the ASC group (p = 0.686). Mesh exposures occurred in 2 patients (12.5%) in the LSC group and 1 patient (7.7%) in the ASC group. There were 5 surgical reinterventions in both groups (LSC: 22.7%; ASC: 26.3%, p = 0.729). Conclusions At long-term follow-up no substantial differences in quality of life, anatomical results, complications, or reinterventions between LSC and ASC were observed. Therefore, the laparoscopic approach is preferable, considering the short-term advantages. Trial registration Dutch Trial Register NTR6330, 18 January 2017, https://www.trialregister.nl/trial/5964
