Effect of Operative Technique on Mesh Exposure in Laparoscopic Sacrocolpopexy

Sacrocolpopexy: The Way I Do It

INTRODUCTION AND HYPOTHESIS

Sacrocolpopexy (SCP) is an established surgical procedure for apical vaginal vault prolapse. There remains significant variation amongst surgeons in both the surgical steps and concomitant surgeries utilised when undertaking an SCP.

METHODS

This review article is aimed at summarising the evidence and providing a detailed update of SCP in modern practice, reviewing contemporary evidence behind its indications, efficacy, outcomes, surgical steps, and complications.

RESULTS

Sacrocolpopexy remains the gold standard for post-hysterectomy apical prolapse based on good long-term outcomes, patient satisfaction and low complication rates. SCP with concomitant total hysterectomy is not recommended owing to high rates of mesh exposure. The laparoscopic approach remains the preferred option in terms of low morbidity, quicker recovery and lower cost than alternative access options. For optimal outcomes an SCP should be performed with monofilament mesh, using absorbable sutures and with a paravaginal repair for cystocele.

CONCLUSIONS

Although SCP has become increasingly utilised for apical prolapse, its established efficacy regarding anatomical outcomes, patient satisfaction, and complications is in the context of post-hysterectomy prolapse. SCP with concomitant total hysterectomy has higher rates of mesh exposure. The efficacy and safety of SCP with sub-total hysterectomy or hysteropexy have not been clearly established and require further assessment through well-designed, rigorous randomised controlled trials.

Clinician perspectives on hysterectomy versus uterine preservation in pelvic organ prolapse surgery: A systematic review and meta-analysis

BACKGROUND

Previous reviews on hysterectomy versus uterine-sparing surgery in pelvic organ prolapse (POP) repair did not consider that the open abdominal approach or transvaginal mesh use have been largely abandoned.

OBJECTIVES

To provide up-to-date evidence by examining only studies investigating techniques currently in use for POP repair.

SEARCH STRATEGY

MEDLINE and Embase databases were searched from inception to January 2023.

SELECTION CRITERIA

We included randomized and non-randomized studies comparing surgical procedures for POP with or without concomitant hysterectomy. Studies describing open abdominal approaches or transvaginal mesh implantation were excluded.

DATA COLLECTION AND ANALYSIS

A random effect meta-analysis was conducted on extracted data reporting pooled mean differences and odds ratios (OR) between groups with 95% confidence intervals (CI).

MAIN RESULTS

Thirty-eight studies were included. Hysterectomy and uterine-sparing procedures did not differ in reoperation rate (OR 0.93; 95% CI 0.74-1.17), intraoperative major (OR 1.34; 95% CI 0.79-2.26) and minor (OR 1.38; 95% CI 0.79-2.4) complications, postoperative major (OR 1.42; 95% CI 0.85-2.37) and minor (OR 1.18; 95% CI 0.9-1.53) complications, and objective (OR 1.38; 95% CI 0.92-2.07) or subjective (OR 1.23; 95% CI 0.8-1.88) success. Uterine preservation was associated with a shorter operative time (-22.7 min; 95% CI -16.92 to -28.51 min), shorter hospital stay (-0.35 days, 95% CI -0.04 to -0.65 days), and less blood loss (-61.7 mL; 95% CI -31.3 to -92.1 mL). When only studies using a laparoscopic approach for both arms were considered, no differences were observed in investigated outcomes between the two groups.

CONCLUSIONS

No major differences were observed in POP outcomes between procedures with and without concomitant hysterectomy. The decision to preserve or remove the uterus should be tailored on individual factors.

Clinical outcomes and complications of laparoscopic sacrocolpopexy with versus without concomitant hysterectomy for pelvic organ prolapse in Hong Kong Chinese patients after median follow-up of 7 years

INTRODUCTION AND HYPOTHESIS

This retrospective cohort study is aimed at comparing outcomes and complications of laparoscopic sacrocolpopexy (LSC) with or without concomitant hysterectomy in the Hong Kong Chinese population.

METHODS

Women with stage II or above uterine or apical vault prolapse who underwent LSC with or without concomitant hysterectomy in a regional referral unit from 2007 to 2019 were included. The primary objectives were to compare the anatomical outcomes by pelvic organ prolapse quantification system (POP-Q) and recurrence of apical vault prolapse (≥stage II). The secondary objective was to compare the functional outcomes and complications. Anatomical recurrence and incidence of mesh exposure were analyzed using the Kaplan-Meier method. Cox proportional hazard regression was performed to identify risk factors of anatomical recurrence.

RESULTS

Seventy-six women were included for analysis. The recurrence rate of apical vault prolapse was 3.9% after a median follow-up time of 83 months (20-190 months). A significant reduction of POP-Q scores of three compartments in both groups of women were demonstrated (p<0.001). There was no difference between the two groups in terms of functional outcomes and complications. 6.6% of women developed mesh exposure. The time to recurrence of apical vault prolapse was shorter in women who had LSC with prior hysterectomy (p =0.019). No risk factors were identified for recurrence of apical vault prolapse.

CONCLUSIONS

Laparoscopic sacrocolpopexy with concomitant hysterectomy is comparable with LSC alone. The recurrence and complication rates are low. We suggest that LSC with concomitant hysterectomy might be offered to women with pelvic organ prolapse, with women's preference taken into account.

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.

Mesh Exposure Following Vaginal Versus Laparoscopic Hysterectomy at the Time of Sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

To compare vaginal mesh exposure rates, adverse events and composite failure within 1 year postoperatively in patients who undergo vaginal hysterectomy with vaginal mesh attachment (TVH) versus laparoscopic hysterectomy with abdominal mesh attachment (TLH) for minimally invasive sacrocolpopexy.

METHODS

This multicenter retrospective cohort study is a secondary analysis of data collected retrospectively at one institution and the multicenter randomized control PACT trial. Women were excluded for no follow-up between 9 months and 2 years postoperatively or undergoing concurrent non-urogynecologic procedures.

RESULTS

Between 2010 and 2019, 182 patients underwent TLH and 132 TVH. There were 15 (4.8%) vaginal mesh exposures: 12 (6.6%) in the TLH and 3 (2.3%) in the TVH group (p = 0.133) with zero mesh erosions. Logistic regression analysis for mesh exposure in the TLH vs. TVH groups controlling for BMI, posterior repair and surgeon training also showed no significant difference (OR 4.8, 95% CI 0.94, 24.8, p = 0.059). The overall intraoperative complication rate was low (19/314, 6.1%) with a higher rate of bladder injury in the TLH group (4.4% vs. 0.8%, p = 0.049). The TLH group had a higher rate of UTI (8.2% vs. 2.3%, p = 0.027) and clean intermittent catheterization (11% vs. 3%, p = 0.009). At 1-year follow-up, there was no difference in composite failure (6%), bulge symptoms (5%) or retreatment (1%) between groups.

CONCLUSIONS

At 1 year, there is no significant difference in vaginal mesh exposure rates between vaginal hysterectomy with vaginal mesh attachment and laparoscopic hysterectomy with abdominal mesh attachment. Both groups have equal efficacy with low rates of complications.

Bowel Obstruction After Sacrocolpopexy: A Case Series

OBJECTIVES

Bowel obstruction after sacrocolpopexy (SC) can cause significant morbidity. The aim of this study was to delineate clinical and surgical factors associated with bowel obstruction after SC and to describe its presentation, management, and sequelae.

METHODS

We performed a retrospective case series of patients who underwent open, laparoscopic, or robotic SC within a large health maintenance organization and a single academic medical center between January 1, 2009, and December 31, 2019.

RESULTS

Of 3,231 patients who underwent SC, 32 (1.0%) experienced a bowel obstruction. Sacrocolpopexy was performed laparoscopically or robotically in 19 (59.4%) and abdominally in 13 (40.6%). The mean time to bowel obstruction was 1.9 years (SD, 2.5; range, 3 days to 8.8 years). In patients who experienced bowel obstruction, medical management was undertaken in 19 (61.3%) cases. Eight of the 13 (61.5%) surgically managed cases underwent bowel resection, and 3 cases (23.1%) reported partial mesh excision. Recurrent obstruction was seen in 2 (10.5%) of the medically managed and 2 (15.4%) of the surgically managed cases.

CONCLUSIONS

Bowel obstruction is a rare complication of SC and our rate of at least 1.0% corroborates those in the literature. Obstruction occurs from days to years after SC. Nonsurgical management was effective in most cases, with low rates of recurrent obstruction. In surgically managed cases, the majority included bowel resection or mesh excision; however, mesh excision was not associated with a subsequent identifiable procedural intervention for recurrent prolapse. These data inform patient counseling and surgical planning before SC and aid in diagnosis and management of bowel obstruction after SC.

Pelvic Organ Prolapse: Controversies in Surgical Treatment

This article discusses a few of the most prominent controversies currently confronting providers and patients when planning for surgical repair of pelvic organ prolapse including preoperative counseling and patient preparedness, preoperative urodynamics and concomitant anti-incontinence procedures, uterine preservation, total versus supracervical hysterectomy at the time of sacrocolpopexy, same-day discharge, and use of telemedicine for routine postoperative care. These current controversies reflect some of the larger questions and themes confronting the field at this time, and this discussion serves to highlight opportunities for further research and stimulate the constructive debate that moves the field forward.

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

OBJECTIVES

This study aimed to compare the incidence of mesh exposure based on route of hysterectomy at the time of minimally invasive sacrocolpopexy. Secondary outcomes included perioperative outcomes and prolapse recurrence.

METHODS

This was a multicenter, retrospective cohort study. Patients who underwent sacrocolpopexy between 2007 and 2017 were stratified by hysterectomy approach: total vaginal hysterectomy (TVH), total laparoscopic or robotic hysterectomy (TLH), and laparoscopic or robotic supracervical hysterectomy (LSH). Total vaginal hysterectomy was subdivided into vaginal and laparoscopic mesh attachment to the cuff. Statistical analyses were performed, with P < 0.05 denoting statistical significance.

RESULTS

Seven institutions participated, and 502 minimally invasive sacrocolpopexies with concomitant hysterectomy were performed by 23 surgeons: 263 TVH, 128 TLH, and 111 LSH. The median follow-up interval was 10 months, and this was significantly different between the groups (months): TVH, 11 (3-13); TLH, 2 (2-9); and LSH, 12 (5-24; P < 0.01). The overall incidence of vaginal mesh exposure was 4.0% (20/502). There were no significant differences in vaginal mesh exposure based on hysterectomy route: TVH, 5.7% (15/263); TLH, 1.6% (2/128); and LSH, 2.7% (3/111; P = 0.11). Within the TVH group, there was no significant difference in vaginal mesh exposure comparing vaginal and laparoscopic mesh attachment: 1.9% (1/52) versus 6.6% (14/211; P = 0.48). Laparoscopic supracervical hysterectomy demonstrated a significantly higher incidence of recurrence compared with TVH and TLH: 10.8% (12/111) versus 3.4% (9/263) and 2.3% (3/128; P < 0.01).

CONCLUSIONS

The incidence of sacrocolpopexy mesh exposure was not significantly different based on route of hysterectomy or mode of mesh attachment to the vagina. There was a significant increase in prolapse recurrence with supracervical hysterectomy.

Occult Uterine Malignancy at the Time of Sacrocolpopexy in the Context of the Safety Communication on Power Morcellation by the FDA

STUDY OBJECTIVE

The objective of this study was to determine the incidence of occult uterine malignancy at the time of sacrocolpopexy with concurrent hysterectomy, in the context of practice pattern changes as a result of the 2014 Food and Drug Administration (FDA) power morcellation safety communication.

DESIGN

Retrospective chart review.

SETTING

Tertiary care referral center in the United States.

PATIENTS

A total of 839 patients who underwent sacrocolpopexy from January 2004 to December 2018.

INTERVENTIONS

All patients received a concurrent hysterectomy without a diagnosis of suspected or confirmed gynecologic malignancy before surgery. Trends of surgeries were compared before and after the 2014 FDA power morcellation safety communication.

MEASUREMENTS AND MAIN RESULTS

Demographic and perioperative data were collected from the system-wide electronic medical record. Operative and pathology reports were reviewed to determine the method of specimen retrieval and specimen pathology results. A total of 238 patients (28.4%) had a hysterectomy at the time of sacrocolpopexy. There were no cases of occult uterine malignancy (0%, 95% CI 0%-1.6%). There was 1 case of borderline tumor of the ovary. The most common mode of hysterectomy over the 15-year period was laparoscopic hysterectomy (n = 84, 35.3%), followed by vaginal hysterectomy (n = 63, 26.5%). After the FDA communication, the most common form of hysterectomy changed significantly to vaginal hysterectomy (n = 35, 55.6%; p <.001). When comparing the first 2 years after the announcement (2014-2016) to the subsequent 2 years (2017-2018), there was again a significant increase in the use of laparoscopic hysterectomy in the latter time period (7.3% vs 40.9%; p <.001).

CONCLUSION

In this cohort of patients undergoing sacrocolpopexy with concurrent hysterectomy, the incidence of occult uterine malignancy was low. After the FDA safety communication, practice patterns with regard to the mode of hysterectomy changed, but the magnitude of these changes were transient.

Robotic-assisted repair of pelvic organ prolapse: a scoping review of the literature

The purpose of this article is to perform a scoping review of the medical literature regarding the efficacy, safety, and cost of robotic-assisted procedures for repair of pelvic organ prolapse in females. Sacrocolpopexy is the “gold standard” repair for apical prolapse for those who desire to maintain their sexual function, and minimally-invasive approaches offer similar efficacy with fewer risks than open techniques. The introduction of robotic technology has significantly impacted the field, converting what would have been a large number of open abdominal sacrocolpopexy (ASC) procedures to a minimally-invasive approach in the United States. Newer techniques such as nerve-sparing dissection at the sacral promontory, use of the iliopectineal ligaments and natural orifice vaginal sacrocolpopexy may improve patient outcomes. Prolapse recurrence is consistently noted in at least 10% of patients regardless of route of mesh placement. Ancillary factors including pre-operative prolapse stage, retention of the cervix, type of mesh implant, and genital hiatus (GH) size all adversely affect surgical efficacy, while trainees do not. Minimally-invasive apical repair procedures are suited to early recovery after surgery protocols but may not be appropriate for all patients. Studies evaluating longer-term outcomes of robotic sacrocolpopexies are needed to understand the relative risk/benefit ratio of this technique. With several emerging robotic platforms with improved features and a focus on decreasing costs, the future of robotics seems bright.

Current surgical management of pelvic organ prolapse: Strategies for the improvement of surgical outcomes

There are a variety of surgical management strategies to help surgeons repair pelvic organ prolapse (POP). Surgical treatment for POP includes native tissue repair, augmentation with mesh, and minimally invasive surgeries. Currently, laparoscopic or robotic techniques for POP repair are increasing in popularity and continuing to evolve. The aim of this review is to present an up-to-date review of surgical techniques used for POP repair and to discuss ways to optimize surgical outcomes.

Medium-term outcomes of laparoscopic sacrocolpopexy or sacrohysteropexy versus vaginal sacrospinous ligament fixation for middle compartment prolapse

OBJECTIVE

To compare laparoscopic sacrocolpopexy (LSC) or sacrohysteropexy (LSH) with vaginal sacrospinous ligament fixation (VSSLF) for middle compartment pelvic organ prolapse (POP).

METHODS

Data were retrospectively reviewed from patients with POP (stage 3 or worse) who underwent LSC, LSH, or VSSLF at a center in Shanghai between January 2009 and March 2014. POP quantification (POP-Q) and Pelvic Floor Distress Inventory scores were compared at the 2-year follow-up.

RESULTS

Data were available for the 2-year follow-up for 102 LSC, 11 LSH, and 94 VSSLF procedures. Compared with patients who had undergone VSSLF, those who had undergone LSC/LSH had better POP-Q C values (P<0.001), longer total vaginal length (TVL) (P<0.001), and lower Aa and Ba scores (P=0.003 and P=0.002, respectively). Apical compartment and overall success rates of LSC/LSH and VSSLF did not differ significantly. Quality of life was improved in both groups (P<0.001). Both groups achieved symptomatic relief, although bowel and urinary functions were significantly improved only in the VSSLF group (P<0.001 for both). More patients in the LSC/LSH group were sexually active at 2 years (P<0.001); improvement in sex life was similar between the groups.

CONCLUSION

Although LSC/LSH achieved longer TVL, both groups achieved the same success rate and improvement in quality of life. Specifically, VSSLF yielded a significant improvement in bowel and urinary function.

Risk factors for mesh extrusion after prolapse surgery: a case-control study

OBJECTIVES

To identify risk factors for mesh extrusion in women undergoing pelvic organ prolapse repair by abdominal sacral colpopexy (ASC) or vaginal mesh procedure (VMP).

METHODS

A multicenter case-control study of patients who underwent ASC or VMP from 2006 to 2009 identified using diagnosis and procedure coding. Cases were defined as women who underwent eligible index procedure with synthetic mesh and had mesh visible through the vaginal epithelium at postoperative evaluation; controls were matched in an approximate 1:3 ratio by date and type of procedure. Two conditional logistic regression models were constructed to assess variables associated with mesh extrusion among women who underwent ASC and among women who underwent VMP.

RESULTS

Eighty-four cases were identified (43 cases after ASC and 41 cases after VMP), and 252 patients were matched as controls (147 patients who underwent ASC and 105 patients who underwent VMP). Concomitant hysterectomy was positively associated with mesh extrusion) among women who underwent ASC (adjusted odds ratio, 3.18; 95% confidence interval, 1.27-7.93; P = 0.01) and VMP (adjusted odds ratio, 3.72, 95% confidence interval, 1.20-11.54; P = 0.02). Age, race, type of vaginal incision, menopausal status, medical comorbidities, and smoking were not significantly associated with extrusion in either group.

CONCLUSIONS

Concomitant hysterectomy is a risk factor for mesh extrusion after ASC and VMPs. This information may be helpful during informed preoperative counseling and planning.
