Route of Hysterectomy at the Time of Sacrocolpopexy: A Multicenter Retrospective Cohort Study

Preoperative prolapse phenotype is predictive of surgical outcome with minimally invasive sacrocolpopexy

BACKGROUND

The gold-standard treatment for advanced pelvic organ prolapse is sacrocolpopexy. However, the preoperative features of prolapse that predict optimal outcomes are unknown.

OBJECTIVE

This study aimed to develop a clinical prediction model that uses preoperative scores on the Pelvic Organ Prolapse Quantification examination to predict outcomes after minimally invasive sacrocolpopexy for stages 2, 3, and 4 uterovaginal prolapse and vaginal vault prolapse.

STUDY DESIGN

A 2-institution database of pre- and postoperative variables from 881 cases of minimally invasive sacrocolpopexy was analyzed. Data from patients were analyzed in the following 4 groups: stage 2 uterovaginal prolapse, stage 3 to 4 uterovaginal prolapse, stage 2 vaginal vault prolapse, and stage 3 to 4 vaginal vault prolapse. Unsupervised machine learning was used to identify clusters and investigate associations between clusters and outcome. The k-means clustering analysis was performed with preoperative Pelvic Organ Prolapse Quantification points and stratified by previous hysterectomy status. The "optimal" surgical outcome was defined as postoperative Pelvic Organ Prolapse Quantification stage <2. Demographic variables were compared by cluster with Student t and chi-square tests. Odds ratios were calculated to determine whether clusters could predict the outcome. Age at surgery, body mass index, and previous prolapse surgery were used for adjusted odds ratios.

RESULTS

Five statistically distinct prolapse clusters (phenotypes C, A, A>P, P, and P>A) were found. These phenotypes reflected the predominant region of prolapse (apical, anterior, or posterior) and whether support was preserved in the nonpredominant region. Phenotype A (anterior compartment prolapse predominant, posterior support preserved) was found in all 4 groups of patients and was considered the reference in the analysis. In 111 patients with stage 2 uterovaginal prolapse, phenotypes A and A>P (greater anterior prolapse than posterior prolapse) were found, and patients with phenotype A were more likely than those with phenotype A>P to have an optimal surgical outcome. In 401 patients with stage 3 to 4 uterovaginal prolapse, phenotypes C (apical compartment predominant, prolapse in all compartments), A, and A>P were found, and patients with phenotype A>P were more likely than those with phenotype A to have ideal surgical outcome. In 72 patients with stage 2 vaginal vault prolapse, phenotypes A, A>P, and P (posterior compartment predominant, anterior support preserved) were found, and those with phenotype A>P were less likely to have an ideal outcome than patients with phenotype A. In 297 patients with stage 3 to 4 vaginal vault prolapse, phenotypes C, A, and P>A (prolapse greater in posterior than in anterior compartment) were found, but there were no significant differences in rate of ideal outcome between phenotypes.

CONCLUSION

Five anatomic phenotypes based on preoperative Pelvic Organ Prolapse Quantification scores were present in patients with stages 2 and 3 to 4 uterovaginal prolapse and vaginal vault prolapse. These phenotypes are predictive of surgical outcome after minimally invasive sacrocolpopexy. Further work needs to confirm the presence and predictive nature of these phenotypes. In addition, whether the phenotypes represent a progression of prolapse or discrete prolapse presentations resulting from different anatomic and life course risk profiles is unknown. These phenotypes may be useful in surgical counseling and planning.

Vaginal-Assisted Laparoscopic Sacrocolpopexy (VALS) with Advanced Pelvic Organ Prolapse

OBJECTIVE

To review advances of the sacrocolpopexy procedure and demonstrate the Vaginal-Assisted Laparoscopic Sacrocolpopexy approach.

DESIGN

Participants who underwent the Vaginal-Assisted Laparoscopic Sacrocolpopexy approach and consented to intra-operative video documentation were included.

SETTING

This research was conducted at a single academic institution.

INTERVENTIONS

Sacrocolpopexy is an abdominal apical suspension that involves placement of mesh between the vaginal apex and anterior longitudinal ligament overlying the S1-S2 vertebrae. Vaginal Assisted Laparoscopic Sacrocolpopexy (VALS), is a modified approach to sacrocolpopexy. After the hysterectomy, the mesh is attached vaginally to the anterior and posterior vaginal walls. Vaginal dissection of the vesicovaginal and rectovaginal spaces by hand is quick and efficient and allows for palpation of needle depth, which can prevent suture tearing and inadequate mesh attachment with non-tactile placement. The surgeon then transitions back to laparoscopy to complete the remainder of the procedure. Recent literature demonstrates similar rates of mesh complications and reoperation for prolapse with concurrent total hysterectomy versus supracervical hysterectomy given the transition to type I polypropylene mesh and reduction in permanent suture use for vaginal mesh attachment. We anticipate an increase in utilization of the VALS technique given multiple benefits of total hysterectomy, including reduced risk of postoperative menses in premenopausal patients, less postoperative pain and better cosmetic outcomes without need for mini-laparotomy or port-site extension for uterine morcellation, and decreased cervical and endometrial cancer risk. Surgical benefits of the VALS technique include shorter anesthesia and operative time and reduces the need for higher level assistance intraoperatively. VALS is also more ergonomic for the surgeon, promoting use of different muscles throughout the case, thus decreasing muscle fatigue and risk of repetitive motion injury.

CONCLUSION

Laparoscopic sacrocolpopexy utilizing transvaginal mesh attachment is another tool in the myriad of techniques to treat advanced pelvic organ prolapse. This technique reduces operative and anesthesia time, minimizes mesh complications while maintaining successful outcomes for patients. VIDEO ABSTRACT.

Transvaginally Adjustable Apical Suspension and Compartment-Specific Tensioning in Vaginal Natural-Orifice Transluminal Endoscopic Surgery Sacrocolpopexy: Cadaveric and Live Patient Experience

Objective

This article provides a systematic approach to performing a vaginal natural-orifice transluminal endoscopic surgery (vNOTES) sacrocolpopexy (SCP) to create an anatomically aligned vaginal axis, an intraoperatively adjustable apical suspension, and variable compartment tensioning.

Methods

The technique presented for vNOTES SCP focuses on: (1) retroperitoneal tunneling; (2) direct sacrum access below the S-1 level, using uterosacral-ligament guidance; (3) transvaginal tensioning of the mesh to ensure both adequate vaginal length and cuff elevation using the DZOH apical-suspension technique; (4) circumvention of intrapelvic laparoscopic suturing; and (5) near-total peritoneal coverage of the mesh arms.

Results

This detailed description of a successful novel technique to perform vNOTES SCP was based on cadaveric experience as well as in live patients that is reproducible on living patients.

Conclusions

This apical suspension technique for vNOTES SCP may be a viable, reproducible, safe, and efficient transvaginal alternative to the commonly practiced minimally invasive approaches that involve abdominal-port placements. (J GYNECOL SURG 40:116).

Risk of postoperative mesh exposure following sacrocolpopexy with supracervical versus total concomitant laparoscopic hysterectomy

INTRODUCTION AND HYPOTHESIS

The primary objective was to compare rates of mesh exposure in women undergoing minimally invasive sacrocolpopexy with concurrent supracervical vs total hysterectomy. We hypothesized there would be a lower risk of mesh exposure for supracervical hysterectomy.

METHODS

This was a retrospective cohort study using the Premier Healthcare Database. Women undergoing sacrocolpopexy with supracervical or total hysterectomy between 2010 and 2018 were identified using Current Procedural (CPT) codes. Complications were identified using CPT and diagnosis codes; reoperations were identified using CPT codes. Mesh exposures were measured over a 2-year period. A multivariable logistic regression was performed with a priori defined predictors of mesh exposure.

RESULTS

This study includes 17,111 women who underwent minimally invasive sacrocolpopexy with concomitant supracervical or total hysterectomy (6708 (39%) vs 10,403 (61%)). Women who underwent supracervical hysterectomy were older (age 60 ± 11 vs 53 ± 13, p < 0.01) and less likely to be obese (4% vs 7%, p < 0.01). Postoperative mesh exposures within 2 years were similar (supracervical n = 47, 0.7% vs total n = 65, 0.62%, p = 0.61). On logistic regression, obesity significantly reduced the odds of mesh exposure (OR 0.2, 95% CI 0.01, 0.8); concomitant slings increased odds (OR 1.91, 95% CI 1.28, 2.83). Supracervical hysterectomy was associated with higher rates of port site hernias (1.3% vs 0.65%, p < 0.01), but lower surgical site infections within 3 months (0.81% vs 1.2%, p = 0.03). Reoperation for recurrent prolapse within 24 months was similar (supracervical n = 94, 1.4% vs total n = 150, 1.4%, p = 0.88).

CONCLUSIONS

Postoperative mesh exposure rates do not significantly differ based on type of concomitant hysterectomy in this dataset.

Recurrence of Anterior Vaginal Prolapse After Robotic Sacrocolpopexy: Does Cervical Preservation Affect Outcome?

IMPORTANCE

Anterior vaginal prolapse (AVP) is the most common site of recurrence after sacrocolpopexy (SCP). Supracervical hysterectomy helps to prevent mesh exposure, but it is unclear if cervical preservation (CP) affects adequate reduction of AVP.

OBJECTIVE

Our primary objective was to determine the difference in AVP recurrence rates in patients who have undergone SCP with or without CP. Secondary outcomes were composite failure and complications rates.

STUDY DESIGN

This was a retrospective cohort analysis of women who underwent robotic SCP between 2012 and 2019 at Kaiser Permanente Southern California. The first cohort included women with CP (prior or concomitant supracervical hysterectomy). The second included women without CP (prior or concomitant total hysterectomy). Primary outcome was defined as recurrent AVP beyond the hymen. Patients without 12-month follow-up were included in demographic and surgical data analysis only.

RESULTS

The charts of 373 patients with CP and 175 without CP were reviewed. Women with CP were more likely to undergo concomitant anterior repair at the time of SCP (14% vs 6%, P < 0.01); however, rates of AVP recurrence were not significantly different between groups (5% vs 3%, P = 0.26). Median follow-up time was 26 months (interquartile range, 14-38 months). Composite failure was similar between groups (17% vs 11%, P = 0.12). Women with CP were more likely to experience asymptomatic apical failure (6% vs 1%, P = 0.03).

CONCLUSIONS

Cervical preservation at the time of SCP is associated with an increased need for concomitant anterior repair but is not associated with higher rates of AVP recurrence or composite failure.

Assessing the Impact of Vaginal Hysterectomy with Vaginal Mesh Attachment on Outcomes and Complications during Minimally Invasive Sacrocolpopexy

STUDY OBJECTIVE

To compare mesh complications and failure rates after 1 year in laparoscopic minimally invasive sacrocolpopexy (MISC) with ultralightweight mesh attached vaginally during total vaginal hysterectomy (TVH), laparoscopically if posthysterectomy (PH), or laparoscopically during supracervical hysterectomy.

DESIGN

Single-center retrospective cohort study.

SETTING

Tertiary referral center.

PATIENTS

Women with symptomatic pelvic organ prolapse who elected for MISC.

INTERVENTIONS

Laparoscopic MISC with ultralightweight mesh attached vaginally during TVH, laparoscopically if PH, or laparoscopically during supracervical hysterectomy. Composite failure was defined as recurrent prolapse symptoms, prolapse past the hymen, or retreatment for prolapse.

MEASUREMENTS AND MAIN RESULTS

Between 2010 and 2017, 650 patients met the inclusion criteria with 278 PH, 82 supracervical hysterectomy, and 290 vaginal hysterectomy patients. Median follow-up was similar for all groups (382 days vs 379 vs 345; p = .31). The majority in all groups were white (66.6%), nonsmokers (74.8%), postmenopausal (82.5%), and did not use estrogen (70.3%). Mesh complications did not differ among groups (1.6% PH, 2.5% supracervical hysterectomy, 2.2% vaginal hysterectomy; p >.99). There was no difference in anatomic failure (5% PH, 1.2% supracervical hysterectomy, 2.1% vaginal hysterectomy; p = .07), reoperation for prolapse (1.4% vs 1.2% vs 0.7%; p = .57), or composite failure (9.0% vs 3.7% vs 4.8%; p = .07).

CONCLUSIONS

TVH with vaginal mesh attachment of ultralightweight mesh had similar adverse events, mesh exposure rates, and failure rates to those of laparoscopic PH sacrocolpopexy or supracervical hysterectomy with laparoscopic mesh attachment.

Rate of Mesh Erosion After Sacrocolpopexy With Concurrent Supracervical Compared With Total Hysterectomy: A Systematic Review and Meta-analysis

OBJECTIVE

To estimate the effect of concomitant supracervical hysterectomy compared with total hysterectomy during abdominal sacrocolpopexy on the rate of mesh erosion by performing a systematic review and meta-analysis of the existing literature.

DATA SOURCES

From database inception through January 2022, we explored MEDLINE, Web of Science, EMBASE, CINAHL, ClinicalTrials.gov , and Cochrane Central Register of Controlled Trials. Studies comparing the rate of mesh erosion in women undergoing abdominal sacrocolpopexy who had concomitant supracervical hysterectomy compared with total hysterectomy were included.

DATA EXTRACTION AND SYNTHESIS

Two reviewers separately ascertained studies, obtained data, and gauged study quality. The rate of mesh erosion was compared, and odds ratios (ORs) with 95% CIs were estimated.

TABULATION, INTEGRATION, AND RESULTS

Nineteen studies with 10,572 women who underwent abdominal sacrocolpopexy were identified, including 4,285 women in the supracervical group and 6,287 women in the total hysterectomy group. The overall mean postprocedure follow-up time was 30.7±15.1 months (median 12.4, range 1.5-44.2). The median (95% CI) point prevalence of mesh erosion was 0.36% (0-1.9%) in women who had supracervical hysterectomy compared with 3.8% (1.8-8.7%) in women who had total hysterectomy. The overall rate of mesh erosion in women who had supracervical hysterectomy was lower compared with women who had total hysterectomy (pooled OR 0.26, 95% CI 0.18-0.38, I 2 0%).

CONCLUSION

In women with symptomatic apical pelvic organ prolapse who undergo abdominal sacrocolpopexy with concomitant hysterectomy, supracervical hysterectomy is associated with a lower risk of mesh erosion compared with total hysterectomy.
