Apical vaginal prolapse surgery: practice patterns and factors guiding route of repair

Surgical Decision-Making: Who Should Be Offered Sacrocolpopexy?

INTRODUCTION AND HYPOTHESIS

Women undergoing surgery for apical pelvic organ prolapse have several medically sound options for specific surgical approaches.

METHODS

We review the principles of shared decision-making as they pertain to surgery for prolapse. We review the literature supporting the superior sacrocolpopexy as a durable treatment for prolapse and the factors that may differentiate it from other repairs in risk and benefit.

RESULTS

We emphasize the importance of collaboration between patients and surgeons in surgical decision-making.

CONCLUSION

All medically appropriate patients who desire reconstructive surgery for prolapse should be offered sacrocolpopexy.

Five-year surgical outcomes of transvaginal apical approaches in women with advanced pelvic organ prolapse

INTRODUCTION AND HYPOTHESIS

In women with advanced prolapse, differences in vaginal apex anchoring sites may impact surgical outcomes over time. The primary aim was to compare 5-year surgical outcomes of uterosacral ligament suspension (ULS) versus sacrospinous ligament fixation (SSLF) in women with advanced (stage III-IV) prolapse.

METHODS

A secondary analysis was conducted in a subset of women with advanced prolapse from a multicenter randomized trial comparing ULS versus SSLF and its extended follow-up, using publicly accessible de-identified datasets. The primary outcome was time to failure, defined as any one of (1) apical descent > 1/3 into the vaginal canal or anterior/posterior compartment beyond the hymen, (2) bothersome vaginal bulge symptoms, or (3) re-treatment. Secondary outcomes include symptom severity measured by the Pelvic Organ Prolapse Distress Inventory (POPDI) and adverse events.

RESULTS

Of 285 women, 90/147 (61.2%) in ULS and 88/138 (63.8%) in SSLF had advanced prolapse. Baseline characteristics did not differ between groups except for median-vaginal deliveries (3.0 [2.0, 5.0] versus 3.0 [2.0, 4.0], p < 0.01). The median time to failure was 1.7 years ULS versus 2.0 years SSLF (p = 0.42). Surgical failure increased over time in both groups with no intergroup difference; by year 5, the estimated failure rate was 67.7% ULS versus 71.5% SSLF (adjusted difference -3.8; 95%CI [-21.9, 14.2]). No differences were noted in individual failure components (p > 0.05). POPDI scores improved over 5 years without intergroup difference (ULS -68.0 ± 61.1 versus SSLF -69.9 ± 60.3, adjusted difference -0.1 [-20.0, 19.9]). No difference in adverse events were observed (p > 0.05).

CONCLUSION

In women with advanced prolapse, surgical failure, symptom severity, and adverse events did not differ between ULS and SSLF over 5 years.

Dynamic magnetic resonance imaging following native tissue vaginal reconstructive surgery; a prospective study

INTRODUCTION AND HYPOTHESIS

To describe the impact of native tissue vaginal reconstruction on pelvic anatomy using dynamic magnetic resonance imaging.

METHODS

This prospective single-cohort observational study involved women undergoing native tissue reconstruction with intraperitoneal vaginal vault suspension for pelvic organ prolapse. Concomitant procedures such as hysterectomy, midurethral sling, and anterior or posterior colporrhaphy were allowed. Enrolled participants underwent dynamic pelvic imaging pre- and postoperatively. Radiographic and anatomic measurements were compared. Secondary outcomes included validated patient questionnaires.

RESULTS

Fourteen participants were included in the analysis. The mean age was 62 years; all participants were Caucasian. Most participants had stage III pelvic organ prolapse. Significant improvements were noted in several radiographic measurements. The average H-line (representing levator hiatus width) with straining maneuvers improved following surgery (7.2 cm preoperatively vs. 6.6 cm postoperatively, p = 0.015). The average M-line (representing levator muscular descent) improved significantly with both straining (4.0 cm preoperatively vs. 3.0 cm postoperatively, p < 0.001) and defecatory maneuvers (6.2 cm preoperatively vs. 5.2 cm postoperatively, p = 0.001). The average size of cystocele improved from 5.6 cm (moderate) preoperatively to 0.7 cm (absent descent) postoperatively (p < 0.001). The average descent of the vaginal apex with defecation preoperatively was 3.0 cm (moderate) and 0 cm (absent descent) postoperatively (p = 0.003). Posterior compartment descent with defecation did not change following surgical intervention (5.8 cm preoperatively vs. 5.2 cm postoperatively, p = 0.056). Pelvic Organ Prolapse Quantification measurements improved in all compartments, and Pelvic Floor Distress Inventory-20 scores improved significantly following surgery (102 preoperatively vs. 30 postoperatively, p < 0.001).

CONCLUSIONS

Native tissue reconstruction with intraperitoneal vaginal vault suspension resulted in significant anatomic improvements, as defined by physical examination and dynamic magnetic resonance imaging.

Vaginal intraperitoneal versus extraperitoneal uterosacral ligament vault suspensions: a comparison of a standard and novel approach

INTRODUCTION AND HYPOTHESIS

Uterosacral ligament suspension surgery is commonly utilized to correct post-hysterectomy vaginal vault prolapse (VVP). Vaginal intraperitoneal uterosacral vault suspension (IUSVS) is a viable option, but intraperitoneal access can be challenging. An alternative approach is an extraperitoneal uterosacral vault suspension (EUSVS). The aim of our study was to compare surgical outcomes of IUSVS and EUSVS in patients with post-hysterectomy VVP.

METHODS

Retrospective cohort study of women who underwent treatment of post-hysterectomy VVP with an IUSVS and EUSVS from May 2016 to January 2019 at our institution. The primary outcome was surgical success that was assessed by a composite outcome for surgical failure, defined as ANY of the following: (1) apical descent > 1/3 of the TVL or anterior or posterior vaginal wall beyond the hymen, (2) retreatment of prolapse, or (3) bothersome vaginal bulge symptoms with a positive response to either of two questions on the PFDI questionnaire. Secondary outcomes included EBL, operative time, duration of hospitalization, and perioperative complications. Two-sample t-tests and chi-square tests were used for the bivariate analysis.

RESULTS

Eighty patients were included (36 IUSVS and 44 EUSVS) with a mean follow-up of 7 months. For our primary outcome, there was no difference in surgical success (IUSVS group 72.22% vs. EUSVS group 81.82%, p = 0.307). Operative time, duration of hospitalization, and EBL were significantly less in the EUSVS group than in the IUSVS group.

CONCLUSIONS

EUSVS demonstrated similar short-term success compared to IUSVS for post-hysterectomy VVP, with shorter operative time, EBL, and length of stay.

Outcomes of native tissue transvaginal apical approaches in women with advanced pelvic organ prolapse and stress urinary incontinence

INTRODUCTION AND HYPOTHESIS

Limited data exist comparing different surgical approaches in women with advanced vaginal prolapse. This study compared 2-year surgical outcomes of uterosacral ligament suspension (ULS) and sacrospinous ligament fixation (SSLF) in women with advanced prolapse (stage III-IV) and stress urinary incontinence.

METHODS

This was a secondary analysis of a multicenter 2 × 2 factorial randomized trial comparing (1) ULS versus SSLF and (2) behavioral therapy with pelvic floor muscle training versus usual care. Of 374 subjects, 117/188 (62.7%) in the ULS and 113/186 (60.7%) in the SSLF group had advanced prolapse. Two-year surgical success was defined by the absence of (1) apical descent > 1/3 into the vaginal canal, (2) anterior/posterior wall descent beyond the hymen, (3) bothersome bulge symptoms, and (4) retreatment for prolapse. Secondary outcomes included individual success outcome components, symptom severity measured by the Pelvic Organ Prolapse Distress Inventory, and adverse events. Outcomes were also compared in women with advanced prolapse versus stage II prolapse.

RESULTS

Success did not differ between groups (ULS: 58.2% [57/117] versus SSLF: 58.5% [55/113], aOR 1.0 [0.5-1.8]). No differences were detected in individual success components (p > 0.05 for all components). Prolapse symptom severity scores improved in both interventions with no intergroup differences (p = 0.82). Serious adverse events did not differ (ULS: 19.7% versus SSLF: 16.8%, aOR 1.2 [0.6-2.4]). Success was lower in women with advanced prolapse compared with stage II (58.3% versus 73.2%, aOR 0.5 [0.3-0.9]), with no retreatment in stage II.

CONCLUSIONS

Surgical success, symptom severity, and overall serious adverse events did not differ between ULS and SSLF in women with advanced prolapse. ClinicalTrials.gov Identifier: NCT01166373.

Quality of Life and Sexual Function 2 Years After Vaginal Surgery for Prolapse

OBJECTIVE

To longitudinally assess the effect of native tissue vaginal apical prolapse repair with anti-incontinence surgery on quality of life, sexual function, and body image between uterosacral and sacrospinous suspensions.

METHODS

A planned secondary analysis was performed on 374 women enrolled in a randomized trial of the two types of native tissue repair for apical prolapse. Condition-specific and generic quality of life, sexual function, overall and de novo dyspareunia, and body image were assessed using validated instruments at baseline; 6, 12, and 24 months postoperatively; and changes from baseline were assessed and compared between surgical groups. General linear mixed models were used for comparisons and clinically significant differences were assessed using minimum important differences.

RESULTS

Of the women randomized, 82% had outcomes available at 2 years. Overall, clinically and statistically significant improvements in generic and condition-specific quality of life and sexual function were observed after surgery. Dyspareunia rates decreased from 25% to 16% by 24 months with only 3% of all women undergoing treatment. De novo dyspareunia occurred in 5% and 10% by 12 and 24 months, respectively. Body image scores also significantly improved from baseline. There were no clinically meaningful or statistically significant differences between groups for any of these outcomes (all P>.05).

CONCLUSION

Native tissue vaginal prolapse surgery results in statistically and clinically significant improvements in quality of life, sexual function, and body image at 24 months with no significant differences between uterosacral and sacrospinous suspensions. One in 10 women experience de novo dyspareunia but few requested treatment.

Factors Influencing Selection of Vaginal, Open Abdominal, or Robotic Surgery to Treat Apical Vaginal Vault Prolapse

OBJECTIVES

This study aimed to determine factors influencing the selection of Mayo-McCall culdoplasty (MMC), open abdominal sacrocolpopexy (ASC), or robotic sacrocolpopexy (RSC) for posthysterectomy vaginal vault prolapse.

METHODS

We retrospectively searched for the records of patients undergoing posthysterectomy apical vaginal prolapse surgery between January 1, 2000, and June 30, 2012, at our institution. Baseline characteristics and explicit selection factors were abstracted from the electronic medical records. Factors were compared between groups using χ tests for categorical variables, analysis of variance for continuous variables, and Kruskal-Wallis tests for ordinal variables.

RESULTS

Among the 512 patients identified who met inclusion criteria, the MMC group (n = 174) had more patients who were older, had American Society of Anesthesiologists class 3+ or greater, had anterior vaginal prolapse grade 3+, desired to avoid abdominal surgery, and did not desire a functional vagina. Patients in the ASC (n = 237) and RSC (n = 101) groups had more failed prolapse surgeries, suspected abdominopelvic pathologic processes, and chronic pain. Advanced prolapse was more frequently cited as an explicit selection factor for ASC than for either MMC or RSC.

CONCLUSIONS

The most common factors that influenced the type of apical vaginal vault prolapse surgery overlapped with characteristics that differed at baseline. In general, MMC was chosen for advanced anterior vaginal prolapse and baseline characteristics that increased surgical risks, ASC for advanced apical prolapse, and ASC or RSC for recurrent prolapse, suspected abdominal pathology, and patients with chronic pain or lifestyles including heavy lifting. Thus, efforts should be made to attempt to control for selection bias when comparing these procedures.
