Abstract |
Background |
Although several different apical suspension procedures are available to women with pelvic organ prolapse, data on long-term efficacy and safety profiles are limited.
Objective |
The primary aim of this study was to analyze longitudinal reoperation risk for recurrent prolapse among the 4 apical suspension procedures over 2 to 15 years. Secondary aims included evaluation of all-cause reoperation, defined as a repeated surgery for the indications of recurrent prolapse and adverse events, and total retreatment rate, which included a repeated treatment with another surgery or a pessary.
Study Design |
This was a multicenter, retrospective cohort study within Kaiser Permanente Southern California that included women who underwent sacrocolpopexy, uterosacral ligament suspension, sacrospinous ligament fixation, or colpocleisis from January 2006 through December 2018. Women who underwent concomitant rectal prolapse repair or vaginal prolapse repair with mesh augmentation were excluded. Data were abstracted using procedural and diagnostic codes through July 2021, with manual review of 10% of each variable. Patient demographics and pessary use were compared using analysis of variance or chi square tests for continuous and categorical variables, respectively. Time-to-event analysis was used to contrast reoperation rates. A Cox regression model was used to perform an adjusted multivariate analysis of the following predictors of reoperation for recurrence: index surgery, concomitant procedures, patient demographics, baseline comorbidities, and year of index surgery. Censoring events included exit from the health maintenance organization and death.
Results |
The cohort included 9681 women with maximum follow-up of 14.8 years. The overall incidence of reoperation for recurrent prolapse was 7.4 reoperations per 1000 patient-years, which differed significantly by type of apical suspension (P<.0001). The incidence of reoperation was lower after colpocleisis (1.4 events per 1000 patient-years) and sacrocolpopexy (4.8 events per 1000 patient-years) when compared with uterosacral ligament suspension (9 events per 1000 patient-years) and sacrospinous ligament fixation (13.9 events per 1000 patient-years). All pairwise comparisons between procedures were significant (P=.0003–.0018) after correction for multiplicity, except for uterosacral ligament suspension or uterosacral ligament hysteropexy vs sacrospinous ligament fixation or sacrospinous ligament hysteropexy (P=.05). The index procedure was the only significant predictor of reoperation for recurrence (P=.0003–.0024) on multivariate regression analysis.
Reoperations for complications or sequelae (overall 2.9 events per 1000 patient-years) also differed by index procedure (P<.0001) and were highest after sacrocolpopexy (4.4 events per 1000 patient-years). The incidence of all-cause reoperation for recurrence and adverse events after sacrocolpopexy, however, was comparable to that of the other reconstructive procedures (P=.1–.4) in pairwise comparisons with Bonferroni correction. Similarly, frequency of pessary use differed by index procedure (P<.0001) and was highest after sacrospinous ligament fixation at 9.3% (43/464).
Conclusion |
Among nearly 10,000 patients undergoing prolapse surgery within a large managed care organization, colpocleisis and sacrocolpopexy offered the most durable obliterative and reconstructive prolapse repairs, respectively. All-cause reoperation rates were lowest after colpocleisis by a large margin, but similar among reconstructive apical suspension procedures.
