Long-term outcomes following abdominal sacrocolpopexy for pelvic organ prolapse

Profiling of the macrophage response to polypropylene mesh burden in vivo

Pelvic organ prolapse (POP) surgical repair with polypropylene mesh (PPM) offers improved anatomical outcomes compared to reconstruction using native tissue. However, PPM repair is hampered by complications, most commonly pain or mesh exposure, occurring in over 10 % of cases. This maladaptive response is, in part, attributed to the host response to a foreign material. Previous studies have demonstrated that mesh properties, such as weight, pore size, and porosity, influence downstream outcomes. In addition, computational models and in vivo mechanistic studies demonstrate that mesh deforms after tensioning in prolapse surgery resulting in collapsed pores and wrinkles. To further investigate the role of pore collapse in mesh complications, PPM was implanted flat, or in configurations that would deform upon tensioning in a POP repair surgery using a non-human primate model. After twelve weeks, we analyzed mesh-tissue complexes to characterize the overall host response, profile the macrophage response, and observe the influence of macrophages in downstream healing outcomes that may lead to complications. The results confirm that mesh deformations reproduce mesh exposure and thinning of vagina. In the PPM configurations with the greatest deformation, mesh burden was the highest, which resulted in an overall decrease in the number of cells within the implantation site. Among the cells that were present, we observed a predominance of M1 pro-inflammatory macrophages. While flat mesh was associated with an organized cellular response, deformed mesh led to an increasingly disorganized response as mesh burden increased. Nearly half of the responding macrophages expressed markers associated both with M1 and M2 phenotypes concurrently, suggesting the possibility of newly recruited macrophages responding even 12 weeks after implantation and/or a repetitive microinjury in which macrophages are continuously recruited and polarized without resolution of the host response. Biochemically, we observed a predominantly M1 pro-inflammatory signaling environment and decreased collagen content as a response to implanted mesh. This study evidences the importance of PPM mesh properties, which may alter mesh burden upon tensioning and impact downstream healing outcomes and emphasizes the need for devices that maintain their geometry following implantation in POP surgical repair.

A biomechanical analysis of cervical fixation methods using shaped meshes for pelvic floor reconstruction in a porcine model

PURPOSE

Pelvic organ prolapse (POP) in women is a common condition. Polypropylene meshes have an important place in the treatment. To date, a biomechanical comparison with a specific mesh design has not been performed for cervical fixation. The purpose of this study was to evaluate the biomechanical properties of different polypropylene mesh shapes and their fastening.

METHODS

Biomechanical testing was performed with a porcine model using the Tension Testing machine Instron 5565®. The cervix was fixated in the Instron 5565® to measure its biomechanical properties. Measurement parameters comprised the maximum load (N), displacement at failure (mm), and stiffness (N/mm). In total, sixty trials were performed. These trials were subdivided into three groups. The first group used Y-shaped meshes fixated with 4 sutures (Y4). The second group used a Y-shaped mesh with 6 sutures (Y6). The third group comprised the standard cervical fixation (SF) utilizing a rectangular mesh with three sutures fixed horizontally on the anterior of the cervix.

RESULTS

Y6 displayed the highest maximum load of 114 ± 19.4 N with displacement at failure 53.2 ± 12.3 mm. SF yielded the highest stiffness value 2.7 ± 0.74 N/mm with the second lowest maximum load and lowest displacement at failure. Y4 displayed the lowest maximum load 73,3 ± 20.5 N, second highest displacement at failure 40.5 ± 9.2 mm, and lowest stiffness 1.99 ± 0.85 N/mm.

CONCLUSION

Y6 displayed the overall highest results for maximum load and displacement at failure. The data derived from this study show that factors such as the shape of the mesh, number of sutures, and location of sutures play an important role in the uniaxial biomechanical properties.

Is There a Diminishing Benefit With Increasing Operative Time of Minimally Invasive Sacrocolpopexy? A Retrospective Analysis

OBJECTIVE

To determine whether there is an operative time threshold beyond which minimally invasive sacrocolpopexy (MI-SCP) is less beneficial than abdominal sacrocolpopexy (ASCP).

DESIGN

Retrospective analysis.

SETTING

The National Surgical Quality Improvement Program (NSQIP) database.

POPULATION

Patients undergoing MI-SCP or ASCP from 2011 to 2018.

METHODS

Preoperative characteristics, operative variables and 30-day postoperative data were collected for each case. Groups were compared using the chi-squared or Kruskal-Wallis tests. Multivariable regression to identify risks of complications and prolonged hospital stay was performed using logistic and negative binomial models. Generalised additive models were applied to account for non-linear relationships between dependent and independent variables.

MAIN OUTCOME MEASURES

Occurrence of any major surgical complications and the length of stay.

RESULTS

13 678 sacrocolpopexies were performed, with the majority (78.6%) being MI-SCP. Although the groups were similar in age and BMI, those undergoing ASCP were more likely to have medical comorbidities. After adjusting for confounders, ASCP was not significantly associated with an increase in the probability of major complications compared to MI-SCP (aOR = 1.59, 95% CI: 0.99-2.54) and there was no significant interaction between procedure and operative time (aOR = 1.06, 95% CI: 0.94-1.20). ASCP was still associated with a prolonged LOS (aIRR = 2.19, 95% CI: 2.00-2.38). The interaction between procedure and operative time was significant (aIRR = 0.958, 95% CI: 0.93-0.98), but the LOS for MI-SCP never exceeded that of ASCP for operative times less than 6 h.

CONCLUSIONS

For surgeries lasting less than 6 h, MI-SCP is associated with similar morbidity and a shorter LOS when compared with ASCP.

Interpretable personalized surgical recommendation with joint consideration of multiple decisional dimensions

Surgical planning can be highly complicated and personalized, where a surgeon needs to balance multiple decisional dimensions including surgical effectiveness, risk, cost, and patient's conditions and preferences. Turning to artificial intelligence is a great appeal. This study filled in this gap with Multi-Dimensional Recommendation (MUDI), an interpretable data-driven intelligent system that supported personalized surgical recommendations on both the patient's and the surgeon's side with joint consideration of multiple decisional dimensions. Applied to Pelvic Organ Prolapse, a common female disease with significant impacts on life quality, MUDI stood out from a crowd of competing methods and achieved excellent performance that was comparable to top urogynecologists, with a transparent process that made communications between surgeons and patients easier. Users showed a willingness to accept the recommendations and achieved higher accuracy with the aid of MUDI. Such a success indicated that MUDI had the potential to solve similar challenges in other situations.

Peri- and Postoperative Complications in Abdominal, Vaginal Extraperitoneal, and Vaginal Intraperitoneal Colpopexy

Introduction Pelvic organ prolapse (POP) is a very common concern for women that can often necessitate surgical intervention, including sacral colpopexy. There are multiple surgical approaches, including vaginal, extraperitoneal, and intraperitoneal. This study aims to identify predictors of the outcomes with the different surgical approaches. Methods This retrospective study utilized data from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) gynecologic-specific database for those who underwent sacral colpopexy for POP. The group was subdivided into surgical approaches that included abdominal, vaginal extraperitoneal, and vaginal intraperitoneal. ANOVA analysis was performed between the three groups, and a multivariate logistic regression was performed to determine the 30-day complication rate. Results Among the 1,275 cases analyzed, 326 (25.6%) utilized an abdominal approach, 425 (33.3%) utilized a vaginal approach, and 524 (41.1%) utilized an extraperitoneal approach. The mean age was significantly higher for patients undergoing a vaginal extraperitoneal (64.5 years) compared to abdominal (62.1 years) and vaginal intraperitoneal (61.6 years). There was no difference in the 30-day complication rate between the surgical approaches on adjusted analysis; however, the vaginal extraperitoneal approach had the longest hospital stay, days from operation to discharge, and total operation time. Conclusion A variety of surgical approaches for sacral colpopexy can be employed. In our study, we show that the 30-day complication rate was similar between the three approaches; however, the complications were only significant with the abdominal approach showing an increased occurrence of bleeding transfusions when compared to the extraperitoneal approach.

Comparing the Efficacy of Laparoscopic Pectopexy and Laparoscopic Sacrocolpopexy for Pelvic Organ Prolapse: A Systematic Review and Meta-Analysis

OBJECTIVE

To assess and compare the efficacy of laparoscopic pectopexy and laparoscopic sacrocolpopexy in managing pelvic organ prolapse.

DATA SOURCES

A systematic search of PubMed, Web of Science, Scopus, and Embase was conducted on July 3, 2024, using the search terms "Pectopexy" AND "Laparoscop*" with no publication date restrictions. Additional sources included citation screening and searches in Google Scholar and ProQuest.

METHODS OF STUDY SELECTION

We included all peer-reviewed, English full-text articles comparing intraoperative, short-term (up to 6 months), or long-term (6 to 12 months) outcomes for laparoscopic pectopexy and sacrocolpopexy in pelvic organ prolapse management.

TABULATION, INTEGRATION, AND RESULTS

Our electronic search identified 269 records, of which 11 were deemed eligible after thorough screening. No additional eligible articles were found through a manual search. The final review included 11 studies, comprising 1043 patients across 4 randomized controlled trials, 6 retrospective studies, and one prospective cohort. Meta-analyses using a random-effects model showed lower operation time (Hedges's g = -0.978 [-1.629, -0.327]; p = .003) and blood loss (Hedges's g = -0.658 [-1.160, -0.155]; p = .010) in pectopexy, with comparable organ injury rates (p > .05) between procedures. Short-term results showed a shorter hospitalization duration for pectopexy (Hedges's g = -0.213 [-0.426, -0.000]; p = .049), while post-surgery outcomes like urinary tract infection, and voiding dysfunction were similar across groups (p > .05). All long-term outcomes were comparable, including apical prolapse recurrence, mesh-related complications, pelvic organ prolapse quantification system scores, constipation, urgency, stress urinary incontinence, dyspareunia, and patient satisfaction (p > .05).

CONCLUSION

This review highlights that laparoscopic pectopexy, despite its theoretical technical advantages, shows comparable intraoperative organ injury rates and similar urinary, defecation, and sexual function outcomes to laparoscopic sacrocolpopexy. However, pectopexy is linked to shorter operative times, less blood loss, and reduced post-operative hospitalization.

Management of Sacrocolpopexy Mesh Complications-A Narrative Review and Clinical Experience from a Large-Volume Center

INTRODUCTION AND HYPOTHESIS

Despite the reputation of sacrocolpopexy as a highly durable reconstructive surgery for pelvic organ prolapse, mesh-related complications remain a significant deterrent for patients. This review discusses the incidence, presentation, diagnosis, management and prevention of sacrocolpopexy mesh complications.

METHODS

We reviewed the literature on sacrocolpopexy focusing on long-term mesh complications and their management. As the literature is not specifically robust, we also give our recommendations based on experience from a large-volume center. Intraoperative videos and images are provided to illustrate findings and management techniques.

RESULTS

Sacrocolpopexy mesh complications include vaginal mesh exposure; bladder or bowel erosions; inflammatory and infectious conditions including spondylodiscitis; and mesh-related pain. Presentation ranges from overt symptoms such as mesh palpated in the vagina to insidious-like spondylodiscitis manifesting as back pain and malaise. Diagnosis relies on methodical history taking, review of operative reports, and a physical examination, with office-based endoscopy studies and imaging as indicated. Various management options have been described in the literature. We recommend an expectant approach for asymptomatic patients; For symptomatic vaginal exposure, we encourage removal of entire mesh arm(s) via an abdominal approach; however, many prefer to utilize a transvaginal or partial excisional approach first. Spondylodiscitis is managed with long-term antibiotics and often requires mesh removal. Prevention strategies include using a lightweight polypropylene mesh attached to well- vascularized vaginal walls, avoiding direct placement on any sutured vaginotomy or cystotomy. Delayed absorbable monofilament suture is non-inferior to permanent suture.

CONCLUSIONS

Sacrocolpopexy mesh complications can be challenging to diagnose and manage. Symptomatic cases often require a proactive approach; listening to patients when they describe persistent symptoms with postoperative onset; a low threshold for further evaluation; and upfront discussion of management options.

Novel Management of Post-laparoscopic Sacrocolpopexy-Associated Overactive Bladder: A Combined Approach of Vaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) Mesh Removal and Fotona Laser Therapy

This case report presents a novel approach for managing overactive bladder (OAB) syndrome following laparoscopic sacrocolpopexy (LSC) using vaginal natural orifice transluminal endoscopic surgery (vNOTES) and Fotona laser therapy. A 73-year-old woman with severe OAB syndrome and pelvic pain after LSC underwent mesh removal via vNOTES. Despite the initial improvement in OAB symptoms, the patient continued to experience persistent urinary issues. Subsequent treatment with Fotona's non-ablative erbium:yttrium-aluminum-garnet (Er:YAG) laser therapy, including Vaginal Erbium Laser (VEL) and Urethral Erbium Laser (UEL), led to the complete resolution of OAB symptoms. The patient's Overactive Bladder Symptom Score (OABSS) significantly improved following combined vNOTES and laser therapy. Follow-up assessments revealed sustained improvements in bladder function and quality of life. This case highlights the potential of combining vNOTES for mesh removal and Fotona laser therapy for managing post-LSC complications, particularly in cases in which mesh-related issues contribute to persistent OAB syndrome. The successful outcome, as evidenced by symptom resolution and improved OABSS, suggests that this approach may offer a viable solution for patients experiencing persistent OAB syndrome following LSC, especially when conventional treatment fails. This report contributes to the limited body of evidence on managing LSC-related OAB syndrome and introduces a promising treatment protocol using Fotona laser therapy, which merits further investigation in larger studies focused on OAB management after pelvic floor surgery.

MRI-Based Structural Failure Comparison between Chinese and American White Women With Prolapse: A Case-Control Study

INTRODUCTION AND HYPOTHESIS

Although some evidence suggests that Chinese and white women might have different pelvic floor anatomy such as levator complex and connective tissue support for pelvic organs, it is unknown if these differences affect the mechanisms of pelvic organ prolapse. We sought to determine whether differences exist in MRI-based structural failure patterns between Chinese and American white women with prolapse.

METHODS

This is a case-control study in different racial cohorts recruited in China and the USA. The Chinese cohort included 19 women with anterior-predominant prolapse and 24 controls with normal pelvic support. The American white cohort included 30 women with anterior-predominant prolapse and 30 controls. Both cohorts underwent the same clinical evaluation and MRI protocol. Three structural support systems were quantified on stress 3D MRI at maximal Valsalva: vaginal factors (length, width); connective tissue attachment (cervix, lateral paravaginal height); and hiatus factors (urogenital hiatus size, major levator ani injury). Abnormal structural support was defined as any measurement outside the normal range defined as the 5th to 95th percentile in controls from the respective cohort. The percentages of the women with abnormal support in the two cohorts were compared.

RESULTS

Among those with prolapse, Chinese women were more likely than white women to have abnormally long vaginal length and width (90% vs 40%, p < 0.001; 53% vs 23%, p = 0.031 respectively). The occurrence of abnormal apical location, paravaginal location, and genital hiatus size ranged from 89 to 100% in Chinese women and from 63 to 80% in white women.

CONCLUSIONS

Prolapse in American white women most commonly involves structural failure of connective tissue attachments and hiatus factors and less frequently involves vaginal wall factors, whereas prolapse in Chinese women frequently involves all support structures.

Incorporating Perineorrhaphy into the LeFort Colpocleisis: A Modified Surgical Approach

INTRODUCTION AND HYPOTHESIS

Perineorrhaphy with levator myorrhaphy is considered a standard part of colpocleisis. Typically, this is done through a separate incision after colpocleisis is completed. We present a video to demonstrate a modified approach to LeFort colpocleisis incorporating perineorrhaphy into the procedure.

METHODS

A rectangular piece of anterior vaginal mucosa is dissected off the underlying fibromuscular tissue starting from 2-3 cm distal to the cervix and ending proximal to the urethrovesical junction. Similarly, a symmetrical posterior vaginal mucosa is dissected starting from the introitus and ending 2-3 cm distal to the cervix. The lateral edges of the rectangles between the anterior and posterior vaginal walls are sutured to create channels. The raw surfaces, including the fibromuscular tissue on the anterior and posterior vagina, are sutured to each other in three rows. Vaginal epithelium is closed continuously starting from the anterior wall and ending with posterior epithelium at the introitus.

RESULTS

Dissection of the anterior and posterior vaginal epithelium mimics standard colporrhaphy. The number of incisions and suturing is decreased by incorporating perineorrhaphy into colpocleisis. Sagittal closure with this technique restores the Aa point to a more anatomical position.

CONCLUSION

These modifications may decrease operative time and de novo stress incontinence and allow less experienced surgeons to consider colpocleisis. Our surgical approach, which incorporates perineorrhaphy into colpocleisis, enables easier adaptation to the procedure and may decrease de novo stress incontinence.

Sacrocolpopexy: Alternatives to Mesh Grafts

INTRODUCTION AND HYPOTHESIS

The ongoing pelvic mesh controversy, coupled with a regulatory pause in using pelvic mesh in some countries, has created a need for mesh-free alternatives for sacrocolpopexy (SCP). This article provides an overview of mesh-free alternatives for SCP.

METHODS

MEDLINE and PubMed searches were conducted to identify studies reporting on autologous and non-autologous biologic grafts for SCP. Identified studies were reviewed by two of the authors (CY and MR).

RESULTS

Emerging evidence on autologous fascia lata (AFL) and rectus sheath (ARS) for SCP is promising, with low donor site morbidity. Non-autologous biologic grafts for SCP are mostly reported to be inferior to mesh.

CONCLUSIONS

Emerging evidence suggests that AFL and ARS might be safe and effective alternative options to mesh SCP. The main advantages of AFL for SCP over ARS are laparoscopy or robot-assisted laparoscopy approaches, and that a larger graft can be safely harvested. The benefits of utilising allografts and xenografts are limited by their reduced durability compared with mesh and patient acceptability.

Patient Perceptions of Pessaries for Treatment of Pelvic Organ Prolapse

IMPORTANCE

A vaginal pessary is a highly effective treatment for patients with pelvic organ prolapse (POP). Patient views of pessaries and how their beliefs affect whether they choose pessary treatment is unknown.

OBJECTIVE

Our objective of this study was to describe the knowledge, understanding, and patient concerns regarding pessary use for POP management.

STUDY DESIGN

We performed a qualitative study of women presenting with POP who were counseled about pessary use at their initial urogynecology visit. Participants completed interviews, which were recorded, de-identified, and transcribed. Transcriptions were coded for major themes by 2 independent researchers.

RESULTS

Twenty patients with an average age of 63 ± 8.5 years participated. Most identified as sexually active (60%) and the majority had a high school education or less (80%). Thematic saturation was reached with themes of "Failure", "Convenience," "Self-Image," "Sexual Relations," "Cleanliness/Hygiene," "Physical Barriers," "Knowledge Deficits," and "Discomfort." Many patients not only viewed a pessary as a less invasive alternative to surgery but also considered it a temporary treatment. Many patients disliked the idea of having a "foreign body" in place and felt it may affect their hygiene. Although most patients believed it would alleviate their POP symptoms, many had concerns about sexual intercourse, discomfort, and fear that it may fall out. Most participants who were not sexually active thought a pessary would increase their sexual confidence.

CONCLUSIONS

Patient opinions about pessaries are often negative with preconceived notions surrounding utilization. Focused counseling addressing concerns and fears may improve a patient's comfort with a pessary as their choice of treatment modality.

Comparison of sexual function between laparoscopic lateral suspension and laparoscopic sacrocervicopexy with the use of the PISQ-IR questionnaire

Introduction and hypothesis

We aimed to analyze the quality of sexual life of patients with apical vaginal wall prolapse who had undergone laparoscopic lateral suspension (LLS) and laparoscopic sacrocolpopexy (LSC).

Methods

We performed a secondary analysis of sexual outcomes of a previous randomized control trial comparing LLS and LSC in 89 women with symptomatic POP stage ≥ II. We evaluated sexually active (SA) and non-sexually active women (NSA) using the Pelvic Organ Prolapse/Incontinence Sexual Questionnaire-IUGA-Revised (PISQ-IR). Women were reviewed over a period of 1 year post-surgery.

Results

Analysis of the entire PISQ-IR questionnaire indicates that surgical treatment of POP resulted in an improvement of the quality of sexual life in 21 (80.76%) in the group of sexually active women after LSC and in 20 (83.33%) in the group of SA patients after LLS. In both groups of patients, dyspareunia was not observed.

Conclusion

In conclusion, the quality of sexual life in SA group of patients improved significantly after both surgical procedures. The quality of sexual life of surveyed women significantly improved after curing POP symptoms.

Risk of Recurrent Prolapse by Extent of Mesh Excision Procedures: A Multicenter Study

IMPORTANCE

There is limited evidence guiding surgeons in how much mesh to resect when treating mesh complications.

OBJECTIVE

The aim of the study was to compare rates of recurrent prolapse after mesh excisional surgical procedures for prolapse mesh complications.

STUDY DESIGN

This multicenter, retrospective cohort study included patients, identified by Current Procedural Terminology codes, who were treated surgically for prolapse mesh complications at 8 institutions between 2010 and 2019. Excisional surgical procedures were categorized as major (total vaginal, extravaginal, and total mesh excisions) or minor (partial vaginal excisions and mesh revisions). The primary outcome was prolapse recurrence 1 year after mesh excision surgery. Secondary outcomes included long-term prolapse recurrence. Prolapse recurrence was evaluated by Kaplan-Meier survival analysis and Cox proportional hazards regression.

RESULTS

Two hundred sixty-one patients met inclusion criteria with 188 (72%) undergoing minor and 73 (28%) major excisions, with a median follow-up time of 1.0 years. Groups differed in parity, location of implant surgery, and number of vaginal compartments involved in excision. Within the first year, major excisions had a higher prolapse recurrence rate (8.7%) than minor excisions (2.9%), P < 0.05. Adjusting for mesh implant type, the hazard ratio for pelvic organ prolapse was 6.1 in the major compared to minor excision. In the entire study period, prolapse recurrence was 33.8% and did not differ between groups.

CONCLUSIONS

Patients undergoing major excision surgical procedures may have higher rates of prolapse at 1 year compared to those undergoing minor excisions. However, in long-term follow-up, recurrence rates were not different. Our findings may aid surgeons in expectation setting prior to excisional procedures.

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.

Racial and Ethnic Disparities in Sacrocolpopexy Approach

IMPORTANCE

Racial inequity elevates risk for certain diagnoses and health disparities. Current data show disparities for Black women when comparing open versus minimally invasive hysterectomy. It is unknown if a similar disparity exists in surgical management of pelvic organ prolapse.

OBJECTIVE

The objective of this study was to determine whether racial or ethnic disparities exist for open abdominal versus minimally invasive sacrocolpopexy.

STUDY DESIGN

Cross-sectional data of the Healthcare Cost and Utilization Project National Inpatient Sample and the Nationwide Ambulatory Surgery Sample for the year 2019 was used. Bivariate analysis identified demographic and perioperative differences between abdominal versus minimally invasive sacrocolpopexy, which were compared in a multivariable logistic regression.

RESULTS

Forty-one thousand eight hundred thirty-seven patients underwent sacrocolpopexy: 35,820 (85.6%), minimally invasive sacrocolpopexy, and 6,016, (14.4%) abdominal sacrocolpopexy. In an unadjusted analysis, Black patients were more likely to undergo an abdominal sacrocolpopexy compared to non-Hispanic White patients (OR 2.14, 95% CI 1.16-3.92, P <0.01). Hispanic patients were more likely to undergo abdominal sacrocolpopexy compared to non-Hispanic White patients (OR 1.69, 95% CI 1.26-2.26, P <0.001). Other factors associated with abdominal sacrocolpopexy are zip code quartile, payer status, composite comorbidity score, hospital control, and hospital bed size. In the regression model, Black patients remained more likely to undergo abdominal sacrocolpopexy compared to those who identified as White (aOR 2, 95% CI 1.26-3.16, P < 0.003). Hispanic patients were more likely to undergo abdominal sacrocolpopexy compared to those who identified as White (aOR 1.73, 95% CI 1.31-2.28, P < 0.001).

CONCLUSION

Abdominal sacrocolpopexy was more likely to occur in patients who identified as Black or Hispanic.

Vaginal host response to polycarbonate urethane, an alternative material for the repair of pelvic organ prolapse

Complications following surgical repair of pelvic organ prolapse (POP) with polypropylene mesh (PPM) are common. Recent data attributes complications, in part, to stiffness mismatches between the vagina and PPM. We developed a 3D printed elastomeric membrane (EM) from a softer polymer, polycarbonate urethane (PCU). EMs were manufactured with more material given the low inherent material strength of PCU. We hypothesized that the EMs would be associated with an improved host response as compared to PPM. A secondary goal was to optimize the material distribution (fiber width and device thickness) within EMs, in regards to the host response. EM constructs (2 × 1 cm2) with varied polymer stiffness, fiber width, and device thickness were implanted onto the vagina of New Zealand white rabbits for 12 weeks and compared to similarly sized PPMs. Sham implanted animals served as controls. Mixed effects generalized linear models were used to compare the effect of construct type accounting for differences in independent variables. EMs had an overall superior host response compared to PPM as evidenced by preservation of vaginal smooth muscle morphology (p-values<0.01), decreased total cellular response to construct fibers (p-values<0.001), and a reduced percent of macrophages (p-values<0.02) independent of how the material was distributed. Both PPM and EMs negatively impacted vaginal contractility and glycosaminoglycan (GAG) content relative to Sham (all p-values<0.001) with EMs having less of an impact on GAGs (p-values<0.003). The results suggest that softer PCU EMs made with more material are well tolerated by the vagina and comprises a future material for POP repair devices. STATEMENT OF SIGNIFICANCE: Prolapse is a debilitating condition in which loss of support to the vagina causes it and the organs supported by it to descend from their normal position in the pelvis. Surgical solutions to rebuild support involves the use of polypropylene mesh which is orders of magnitude stiffer than the vagina. This mismatch results in complications including exposure of the mesh into the vagina and pain. To provide an innovative solution for women, we have developed an elastomeric membrane from a soft polymer that matches the stiffness of the vagina. Here, we show in a rabbit animal model that this device incorporates better into the vagina and is associated with an overall improved host response as compared to polypropylene mesh.

Minimally Invasive Total Versus Supracervical Hysterectomy With Sacrocolpopexy

IMPORTANCE

Limited data exist comparing total laparoscopic hysterectomy (TLH) versus laparoscopic supracervical hysterectomy (LSCH) at the time of minimally invasive sacrocolpopexy for uterovaginal prolapse.

OBJECTIVES

The objective of this study was to compare TLH versus LSCH at the time of minimally invasive sacrocolpopexy for uterovaginal prolapse, hypothesizing that LSCH would demonstrate a higher proportion of recurrent prolapse, but a lower proportion of mesh exposures.

STUDY DESIGN

This was a retrospective, secondary analysis comparing a prospective cohort of patients undergoing TLH sacrocolpopexy versus a retrospective cohort of patients who had undergone LSCH sacrocolpopexy. Our primary outcome was composite anatomic pelvic organ prolapse recurrence (prolapse beyond hymen, apical descent > half vaginal length, retreatment). Secondary outcomes included vaginal mesh exposures.

RESULTS

There were 733 procedures: 184 (25.1%) TLH sacrocolpopexy and 549 (74.9%) LSCH sacrocolpopexy. Median follow-up was longer in the TLH cohort (369 [IQR 354-386] vs 190 [IQR 63-362] days, P < 0.01). There was no difference in composite prolapse recurrence between groups on bivariable analysis (3.3% vs 4.7%, P = 0.40). However, multivariable logistic regression demonstrated that TLH sacrocolpopexy had lower odds of composite pelvic organ prolapse recurrence than LSCH sacrocolpopexy (OR 0.21, 95% CI 0.05-0.82, P = 0.02). Among procedures with lightweight mesh types, TLH demonstrated a higher proportion of mesh exposures compared to LSCH (10 [5.4%] vs 4 [1.1%], P < 0.01); however, this was not significant after controlling for confounders (OR 4.51, 95% CI 0.88-39.25, P = 0.08). There were no differences in retreatment or reoperation.

CONCLUSION

For the treatment of uterovaginal prolapse, both TLH and LSCH are acceptable methods of concomitant hysterectomy at the time of minimally invasive sacrocolpopexy, albeit with likely different risk profiles.

Long-Term Outcomes of Tension-Free Vaginal Tape Obturator: Efficacy and Safety at Long-Term Follow-Up

Background/Objectives: The use of tension-free vaginal tape obturator (TVT-O) for the treatment of stress urinary incontinence (SUI) has been widely debated over the last decade due to the lack of evidence on its long-term outcomes. The aim of this prospective study is to assess, for the first time in the available literature, the efficacy and safety of TVT-O implantation in women with pure SUI over a 17-year follow-up period. Methods: We included all women who complained of pure SUI symptoms (confirmed urodynamically) and underwent the TVT-O procedure. An objective cure was defined as the absence of urine leakage during the stress test, while subjective outcomes were assessed by means of the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF), the Patient Global Impression of Improvement (PGI-I) scale, and a Visual Analogue Scale (VAS). Results: A total of 70 patients who met the inclusion criteria underwent the TVT-O procedure. During the study period, no patients were lost to follow-up, and all women completed the last evaluation at the 17-year mark. At the 17-year mark of follow-up, 62 out of 70 patients (81.4%) were subjectively cured, and 56 out of 70 (80%) patients were objectively cured. These data do not reveal any significant variation in the surgical outcomes over the follow-up period. We recorded seven (10%) tape exposure (three occurred after 10 years and four after 17 years). Among these, one woman was symptomatic for dyspareunia and "hispareunia". All patients with mesh exposure were treated with partial removal and re-suture of the vagina, but only one developed the recurrence of SUI that required a second treatment with a urethral bulking agent (UBA). In all other cases, women reported a complete resolution of symptoms without any worsening of the urinary continence. No significant bladder or urethral erosion was recorded. Conclusions: The 17-year evaluation of the TVT-O procedure has shown that it is a highly effective and safe option for the treatment of female SUI. Although there was an increased risk of tape exposure 17 years after implantation, no serious complications were reported, and no patient required the total removal of the sling.

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.

At the Scrub Sink: Permanent Versus Absorbable Sutures for Sacrocolpopexy Vaginal Mesh Fixation

ABSTRACT

Thirty years ago, open sacrocolpopexy was the main route for the procedure, and at that time, most surgeons used permanent sutures to attach the mesh to the vagina. With the changes to laparoscopic and robotic-assisted routes, some urogynecologists started using delayed absorbable sutures while others continued using permanent sutures. The current data suggest no increased failures with delayed absorbable sutures. Given that the risk of suture exposure is almost eliminated with delayed absorbable sutures, it is reasonable to use delayed absorbable sutures in attaching the mesh to the vagina over permanent sutures. Regardless of the suture selection, the 10% long-term mesh exposure rate after sacrocolpopexy should prompt us to continue discussing and working on solutions to lower the mesh exposure rate and improve prolapse surgery outcomes for our patients.

Three-year outcomes of a randomized clinical trial of perioperative vaginal estrogen as adjunct to native tissue vaginal apical prolapse repair

BACKGROUND

As the muscular and connective tissue components of the vagina are estrogen responsive, clinicians may recommend vaginal estrogen to optimize tissues preoperatively and as a possible means to reduce prolapse recurrence, but long-term effects of perioperative intravaginal estrogen on surgical prolapse management are uncertain.

OBJECTIVE

This study aimed to compare the efficacy of perioperative vaginal estrogen vs placebo cream in reducing composite surgical treatment failure 36 months after native tissue transvaginal prolapse repair.

STUDY DESIGN

This was an extended follow-up of a randomized superiority trial conducted at 3 tertiary US sites. Postmenopausal patients with bothersome anterior or apical vaginal prolapse were randomized 1:1 to 1-g conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally twice weekly for ≥5 weeks preoperatively and continued twice weekly for 12 months postoperatively. All participants underwent vaginal hysterectomy (if the uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The primary report's outcome was time to failure by 12 months postoperatively, defined by a composite outcome of objective prolapse of the anterior or posterior walls beyond the hymen or the vaginal apex descending below one-third the total vaginal length, subjective bulge symptoms, and/or retreatment. After 12 months, participants could choose to use-or not use-vaginal estrogen for atrophy symptom bother. The secondary outcomes included Pelvic Organ Prolapse Quantification points, subjective prolapse symptom severity using the Patient Global Impression of Severity and the Patient Global Impression of Improvement, and prolapse-specific subscales of the 20-Item Pelvic Floor Distress Inventory and the Pelvic Floor Impact Questionnaire-Short Form 7. Data were analyzed as intent to treat and "per protocol" (ie, ≥50% of expected cream use per medication diary).

RESULTS

Of 206 postmenopausal patients, 199 were randomized, and 186 underwent surgery. Moreover, 164 postmenopausal patients (88.2%) provided 36-month data. The mean age was 65.0 years (standard deviation, 6.7). The characteristics were similar at baseline between the groups. Composite surgical failure rates were not significantly different between the estrogen group and the placebo group through 36 months, with model-estimated failure rates of 32.6% (95% confidence interval, 21.6%-42.0%) and 26.8% (95% confidence interval, 15.8%-36.3%), respectively (adjusted hazard ratio, 1.55; 95% confidence interval, 0.90-2.66; P=.11). The results were similar for the per-protocol analysis. Objective failures were more common than subjective failures, combined objective and subjective failures, or retreatment. Using the Patient Global Impression of Improvement, 75 of 80 estrogen participants (94%) and 72 of 76 placebo participants (95%) providing 36-month data reported that they were much or very much better 36 months after surgery (P>.99). These data included reports from 51 of 55 "surgical failures." Pelvic Organ Prolapse Quantification measurements, Patient Global Impression of Severity scores, and prolapse subscale scores of the 20-Item Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaire-Short Form 7 all significantly improved for both the estrogen and placebo groups from baseline to 36 months postoperatively without differences between the groups. Of the 160 participants providing data on vaginal estrogen usage at 36 months postoperatively, 40 of 82 participants (49%) originally assigned to the estrogen group were using prescribed vaginal estrogen, and 47 of 78 participants (60%) assigned to the placebo group were using vaginal estrogen (P=.15).

CONCLUSION

Adjunctive perioperative vaginal estrogen applied ≥5 weeks preoperatively and 12 months postoperatively did not improve surgical success rates 36 months after uterosacral or sacrospinous ligament suspension prolapse repair. Patient perception of improvement remained very high at 36 months.

Apical Suspension Repair for Vaginal Vault Prolapse: A Randomized Clinical Trial

Importance

The optimal surgical repair of vaginal vault prolapse after hysterectomy remains undetermined.

Objective

To compare the efficacy and safety of 3 surgical approaches for vaginal vault prolapse after hysterectomy.

Design, Setting, and Participants

This was a multisite, 3-arm, superiority and noninferiority randomized clinical trial. Outcomes were assessed biannually up to 60 months, until the last participant reached 36 months of follow-up. Settings included 9 clinical sites in the US National Institute of Child Health and Human Development (NICHD) Pelvic Floor Disorders Network. Between February 2016 and April 2019, women with symptomatic vaginal vault prolapse after hysterectomy who desired surgical correction were randomized. Data were analyzed from November 2022 to January 2023.

Interventions

Mesh-augmented (either abdominally [sacrocolpopexy] or through a vaginal incision [transvaginal mesh]) vs transvaginal native tissue repair.

Main Outcomes and Measures

The primary outcome was time until composite treatment failure (including retreatment for prolapse, prolapse beyond the hymen, or prolapse symptoms) evaluated with survival models. Secondary outcomes included patient-reported symptom-specific results, objective measures, and adverse events.

Results

Of 376 randomized participants (mean [SD] age, 66.1 [8.7] years), 360 (96%) had surgery, and 296 (82%) completed follow-up. Adjusted 36-month failure incidence was 28% (95% CI, 20%-37%) for sacrocolpopexy, 29% (95% CI, 21%-38%) for transvaginal mesh, and 43% (95% CI, 35%-53%) for native tissue repair. Sacrocolpopexy was found to be superior to native tissue repair (adjusted hazard ratio [aHR], 0.57; 99% CI, 0.33-0.98; P = .01). Transvaginal mesh was not statistically superior to native tissue after adjustment for multiple comparisons (aHR, 0.60; 99% CI, 0.34-1.03; P = .02) but was noninferior to sacrocolpopexy (aHR, 1.05; 97% CI, 0-1.65; P = .01). All 3 surgeries resulted in sustained benefits in subjective outcomes. Mesh exposure rates were low (4 of 120 [3%] for sacrocolpopexy and 6 of 115 [5%] for transvaginal mesh) as were the rates of dyspareunia.

Conclusions and Relevance

Among participants undergoing apical repair for vaginal vault prolapse, sacrocolpopexy and transvaginal mesh resulted in similar composite failure rates at study completion; both had lower failure rates than native tissue repair, although only sacrocolpopexy met a statistically significant difference. Low rates of mesh complications and adverse events corroborated the overall safety of each approach.

Outcomes of Abdominal Apical Suspension Using Mesh in a Tertiary Training Hospital: A Seven-year Retrospective Review

Background

Pelvic organ prolapse (POP) is an inconvenience that can affect a woman's well-being. Reconstructive pelvic floor surgery involves repairing defects in the endopelvic fascia and pelvic floor musculature as close to the physiologic and anatomic norm. The cornerstone of successful prolapse repair is a strong apical support.

Objective

The aim of the study is to determine the outcomes of abdominal sacrocolpopexy (ASC) and abdominal sacrohysteropexy (ASH) in the Philippines.

Methods

The study utilized a descriptive study design to compare the pre-operative and post-operative Pelvic Organ Prolapse Quantification Score (POP-Q Score), presence of mesh complications, and urinary/bowel symptoms in patients operated within 2010-2016 in a Philippine tertiary training hospital. Based on recovered charts and inclusion/exclusion criteria, this study sampled 34 of 50 patient records. Statistical measures of median and range were used to describe pre-operative and post-operative POP-Q scores in any two follow-ups within 6-, 12-, 18-, and 24-month interval. The objective success rate and incidence of urinary/bowel symptoms were described using frequencies and percentages. Presence of any mesh erosion was noted for each follow-up. McNemar's test was applied to assess the comparative occurrence of each symptom comparing between the pre-operative and first follow-up periods.

Results

ASC had a success rate of 73.7% at six months and 56.3% at 12 months post-surgery. ASH showed an 84.6% success rate at six months and 71.4% at 12 months. Apical support has a 97% success rate without affecting the anterior or posterior compartments. Out of 20 ASC patients, 5 (25%) exhibited anterior compartment descent, whereas two out of 14 ASH patients (14.2%) had the same condition. It is observed that the anterior vaginal wall has the higher tendency to descend after reconstructive surgery, independent of route or technique. In addition, not all patients with surgical prolapse beyond -1 experienced symptomatic vaginal bulges. Overall, a notable decrease in the occurrence of urine symptoms was seen after the surgery. No mesh erosion was seen within the initial two years of follow-up but there was a single reported instance of abdominal hernia, an uncommon consequence.

CONCLUSION

This study demonstrated that ASC and ASH have good success rate in apical support; however, descent of the anterior or posterior compartment diminishes the overall success rate in terms of over-all objective POP-Q score. Both resulted to improvement in symptoms with minimal complications.

Complications of Pelvic Prolapse Surgery Using Mesh: A Systematic Review

BACKGROUND

Pelvic organ prolapse (POP) is a public health problem that influences millions of women around the globe, and it has a significant impact on the quality of life. From the FDA statement regarding the complications of using mesh implants in POP surgery to studies that have shown the benefits and side effects, we conducted a systematic review investigating the complications associated with surgical mesh implantation for POP repair.

METHODS

Relevant studies were identified through a comprehensive search of scientific databases. Studies evaluating the use of mesh in POP surgery and reporting on associated complications were included.

RESULTS

Among 2816 studies, 28 studies met the research criteria, with a total number of 8958 patients, revealing that in laparoscopic mesh surgery, the rate of mesh exposure was lower compared to vaginal mesh surgery, among other complications.

CONCLUSIONS

Laparoscopic mesh surgery is superior as a long-term approach for POP repair compared to vaginal mesh surgery, offering lower complication rates and potentially better anatomical success. However, vaginal mesh surgery remains a valuable option for patients who are unsuitable for laparoscopy due to specific factors. Future research should explore alternative techniques, like pectopexy with or without mesh, to further improve surgical outcomes and patient experience.

Flaps and Grafts in Robotic Reconstructive Surgery

PURPOSE OF REVIEW

The robotic approach is increasingly popular in reconstructive urology. Reconstructive surgeons have commonly used flaps and grafts for obliterating dead space including tissue interposition or as an alternative to mesh in addressing lower urinary tract dysfunction. Advantages of the robotic approach are less incisional pain, excellent visualization in the deep pelvis, and improved surgeon ergonomics. In this literature review, we describe flaps and grafts used in lower urinary tract robotic reconstructive urology, serving as an almanac for these techniques.

RECENT FINDINGS

Omental, peritoneal, vertical rectus abdominis musculocutaneous (VRAM), sigmoid epiploica, gracilis flaps, and Alloderm™ have been reported for tissue interposition during fistula repair. Fascia lata has been described as a mesh alternative for robotic sacrocolpopexy. Besides providing interposition, flaps support native tissue healing and blood supply. Grafts are easy to use with low patient morbidity, but rely on the blood supply at the recipient site. Robotic reconstruction is an emerging field, and more studies are needed to define the best uses for each flap and graft as well as strategies to maximize outcomes and minimize morbidity.

Efficacy and safety of transvaginal mesh repair in a cohort with a minimum of 10-year follow-up

Although transvaginal mesh (TVM) repair is no longer used in some countries, long-term outcomes after TVM surgery are of great importance globally. However, reports with follow-up >10 years are limited. Thus, this study aimed to report outcomes in a prospective cohort with at least 10 years of follow-up. Women with stage III-IV symptomatic prolapse were approached consecutively from 2008 to 2013 at one tertiary hospital. The main outcome measure was symptomatic failure. Secondary outcomes included anatomic failure, recurrence, patient satisfaction, complications, and reoperation. The Kaplan-Meier curve was used to estimate the cumulative failure rate. Of the 121 patients enrolled in the study, 103 (85.1%) completed a median follow-up of 11 years. The estimated probability rates of symptomatic and anatomic failure were 17.6% and 8.8% in 11 years, respectively. The estimated incidence of symptomatic failure increased by 8.2% between 5 and 11 years; however, the corresponding rate for anatomic failure was 3.7%. The most common complication was vaginal mesh exposure, and its estimated probability increased from 19.3% to 28.4% from 5 to 11 years, respectively. Office trimming resolved 80.0% of vaginal exposures. These patients did not report decreased overall satisfaction. Patients with vaginal mesh exposure requiring>3 office procedures or mesh removal in the operating room (5.8% by 11 years) had lower satisfaction rates (P<0.01) and were defined as having severe mesh exposure. The rates of postoperative pain, reoperation, and Patient Global Impression of Improvement ⩾2 were 2.5%, 3.3%, and 94.2%, respectively. The results of this study implied that TVM treatment gradually increased the symptomatic failure rate but provided durable anatomical support of the vaginal wall. Vaginal mesh exposure was common in women who were largely not sexually active; however, 80% of the cases could be managed in the outpatient clinic, which did not affect patient satisfaction.

Measuring Pelvic Organ Prolapse: An Evolution

INTRODUCTION AND HYPOTHESIS

Advances in our understanding of pelvic organ prolapse (POP) have been made with the introduction of valid, reliable measures of anatomy and patient-reported outcome measures.

METHODS

This review provides an overview of the evolution of POP measurement and its implications for clinical practice and research.

RESULTS

Since the introduction of the Pelvic Organ Prolapse Quantification (POPQ), studies have demonstrated that some degree of loss of anatomic support is normal, with as many as 40% of normal women having stage 2 prolapse. Vaginal support is dynamic and can wax and wane but is largely stable over time. Vaginal bulge symptoms are the most reliable and specific symptom for POP and the hymen is an important threshold for symptom development. Most pelvic floor symptoms have only weak to moderate correlation with the anatomic severity of POP. Treatment success rates are highly variable depending upon criteria used and definitions of anatomic success commonly used are too strict and often not clinically relevant. There is substantial discordance between subjective and anatomic measures of success, and both are dynamic, fluctuating between success and failure for many patients without intervening treatment.

CONCLUSIONS

Pelvic organ prolapse is multidimensional, dynamic, and has a complex impact on patients. Patients' symptoms are more clinically relevant than anatomic support. Symptomatic cure, particularly the absence of vaginal bulge symptoms, is more clinically relevant than anatomic cure and composite outcomes can be misleading and overestimate failure rates. Future studies should compare treatments using continuous variables along multiple dimensions rather than using composite outcomes or dichotomizing patients into success or failure.

Long-Term Mesh Exposure 5 Years Following Minimally Invasive Total Hysterectomy and Sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

The objective was to assess long-term mesh complications following total hysterectomy and sacrocolpopexy.

METHODS

In this second extension study, women from a multicenter randomized trial were followed for more than 36 months after surgery. Owing to COVID-19, participants were assessed through either in-person visits or telephone questionnaires. The primary outcome was the incidence of permanent suture or mesh exposure. Secondary outcomes included surgical success and late adverse outcomes.

RESULTS

Out of the 200 initially enrolled participants, 82 women took part in this second extension study. Among them, 46 were in the permanent suture group, and 36 in the delayed absorbable group. The mean follow-up duration was 5.3 years, with the cumulative mesh or suture exposure of 9.9%, involving 18 cases, of which 4 were incident cases. Surgical success after more than 5 years stood at 95%, with few experiencing bothersome bulge symptoms or requiring retreatment. No serious adverse events occurred, including mesh erosion into the bladder or bowel. The most common adverse events were vaginal pain, bleeding, dyspareunia, and stress urinary incontinence, with no significant differences between suture types.

CONCLUSION

The study found that mesh exposure risk gradually increased over time, reaching nearly 10% after more than 5 years post-surgery, regardless of suture type. However, surgical success remained high, and no delayed serious adverse events were reported.

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).

A randomized clinical trial comparing internal and external pessaries in the treatment of pelvic organ prolapse in postmenopausal women: A pilot study

INTRODUCTION AND HYPOTHESIS

Internal vaginal pessary is among the leading treatments for pelvic organ prolapse (POP); however, it has a high adverse event rate. An external pessary was recently developed as an alternative. The study's objective was to compare the efficacy of external and internal pessaries in treating POP in postmenopausal women.

METHODS

This parallel randomized (1:1 ratio) open-blind study included 40 symptomatic women with stage 2 or 3 POP. They were randomized into two groups: group 1 (internal pessary) and group 2 (external pessary) (n = 20 in each); and evaluated at the start of and 3 months after the treatment. Statistical analysis was performed to compare the results within and between the groups before and after the 3-month treatment.

RESULTS

The groups were homogeneous, except for the variables previous pregnancies (p = 0.030) and POP-Q score of apical prolapse (p = 0.023) whose values were higher in group 2. A significant improvement in quality of life was observed in both groups after 3 months of follow-up; however, internal pessaries were found to be more effective (p < 0.001). In group 1 there were differences between the initial and final POP-Q scores of anterior (0.004) and apical prolapse (p = 0.005). The complication rate associated with internal pessary use was high (p = 0.044).

CONCLUSIONS

The present data suggested that external pessaries have a similar effect to internal ones for the treatment of POP and improvement of the quality of life of postmenopausal women.

Longitudinal Reoperation Risk After Apical Prolapse Procedures in Women Aged 65 Years and Older

OBJECTIVE

To describe longitudinal reoperation risk among older women undergoing surgery for apical pelvic organ prolapse (POP) and to compare risk of reoperation for prolapse and complications among different surgical approaches.

METHODS

This nationwide, retrospective cohort study evaluated older adult women (aged 65 years and older) within the Centers for Medicare & Medicaid Services' (CMS) 5% LDS (Limited Data Set) who underwent sacrocolpopexy, uterosacral ligament suspension (USLS), sacrospinous ligament fixation (SSLF), or colpocleisis, or their uterine-preserving equivalents, from January 1, 2011, to December 31, 2018, with follow-up through 2019. The primary outcome was overall reoperation, and secondary outcomes included reoperation for POP and for complications. Rates were compared using χ 2 tests for categorical variables, Wilcoxon rank-sum for continuous variables and Kaplan Meier estimates of cumulative incidence. Death and exit from CMS insurance were considered as censoring events. We used cumulative incidence to calculate reoperation risk as a function of time at 1 year or more, 3 years or more, and 7 years or more.

RESULTS

This cohort included 4,089 women who underwent surgery to treat apical POP from 2011 to 2018: 1,034 underwent sacrocolpopexy, 717 underwent USLS, 1,529 underwent SSLF, and 809 underwent colpocleisis. Demographics varied among patients for each POP surgery. Patients who underwent the different surgeries had differences in age ( P <.01), Charlson Comorbidity Index score ( P <.01), diabetes ( P <.01), chronic obstructive pulmonary disease ( P <.01), hypertension ( P <.01), chronic pain ( P =.01), congestive heart failure ( P <.01), and concomitant hysterectomy ( P <.01). Reoperation rates were low and increased over time. The overall reoperation risk through 7 years was 7.3% for colpocleisis, 10.4% for USLS, 12.5% for sacrocolpopexy, and 15.0% for SSLF ( P <.01). Reoperation for recurrent POP through 7 years was 2.9% for colpocleisis, 7.3% for sacrocolpopexy, 7.7% for USLS, and 9.9% for SSLF ( P <.01). Reoperation for complications through 7 years was 5.3% for colpocleisis, 8.2% for sacrocolpopexy, 6.4% for USLS, and 8.2% for SSLF ( P <.01).

CONCLUSION

The type of surgical repair is significantly associated with long-term risk of reoperation. Colpocleisis offers the least likelihood of reoperation for prolapse, followed by sacrocolpopexy; colpocleisis followed by USLS has the least risk of long-term reoperation for complication.

A Randomized Clinical Trial Comparing Dubuisson Laparoscopic Lateral Suspension with Laparoscopic Sacropexy for Pelvic Organ Prolapse: Short-Term Results

BACKGROUND

Laparoscopic sacrocolpopexy (LSC) is the gold standard for the treatment of apical prolapse, although dissection of the promontory may be challenging. Laparoscopic lateral suspension (LLS) with mesh is an alternative technique for apical repair with similar anatomical and functional outcomes, according to recent studies. The purpose of this study was to compare these operative techniques.

METHODS

Women with uterine Pelvic Organ Prolapse Quantification (POP-Q) stage 2 were enrolled in this prospective study and were randomly allocated to the LLS or LSC group. At the 12-month follow-up, primary measures included both anatomical and functional outcomes. Perioperative parameters and complications were recorded.

RESULTS

A total of 93 women were randomized, 48 in the LLS group and 45 in the LSC group, with 2 women lost to follow-up in both groups. LSC anatomic success rates were 81.82% for the apical compartment and 95.22% for the anterior compartment. LLS anatomic success rates for the apical and anterior compartments were 90% and 92.30%, respectively. The mean operative time for LLS was 160.3 min, while for LSC it was 168.3 min. The mean blood loss was 100 mL in both procedures. Conversion to laparotomy was necessary in three women. Mesh erosion was not observed in any of the cases. In terms of the complication, Clavien-Dindo grade 1 was observed in two patients in the LLS group and a complication rated grade 3b was observed in one patient in LSC group.

CONCLUSIONS

LLS is a good alternative to LSC, with promising anatomical and quality-of-life results.

Characteristics Associated With Surgical Failure After Native Tissue Apical Prolapse Repair

OBJECTIVE

To identify clinical and demographic characteristics associated with prolapse recurrence by 12 months after native tissue transvaginal repair.

METHODS

This was a planned secondary analysis of a randomized trial including postmenopausal participants with stage 2 or greater apical or anterior vaginal prolapse scheduled for surgical repair at three U.S. sites. Participants underwent vaginal hysterectomy (if uterus was present) and standardized uterosacral or sacrospinous ligament suspension at the surgeon's discretion. The intervention was perioperative (5 weeks or more preoperatively and 12 months postoperatively) vaginal estrogen compared with placebo cream. The primary outcome was time to failure by 12 months after surgery, defined by objective prolapse of the anterior or posterior walls beyond the hymen or the apex descending more than one-third of the vaginal length, symptomatic vaginal bulge, or retreatment. For this analysis, participants were grouped according to failure compared with success, and multiple factors were compared, including age, time since menopause, race and ethnicity, parity, body mass index (BMI), baseline genital hiatus measurement, prolapse stage and point of maximal prolapse, surgery type (uterosacral or sacrospinous ligament suspension), and concomitant procedures. Factors were assessed for association with the hazard of surgical failure using Cox proportional hazards models, adjusted for site and treatment group. Factors with P <.50 from this analysis were considered for inclusion in the final multivariable model; site and treatment group were kept in this model.

RESULTS

One hundred eighty-six participants underwent surgery; 183 provided complete data. There were 30 failures (16.4%) and 153 successes (83.4%) at 12 months. On bivariate analysis, failure was associated with decreasing age, shorter duration since menopause, Latina ethnicity, and greater baseline genital hiatus. In the final multivariable model, which included age, BMI, and point of maximal prolapse, only age remained significantly associated with surgical failure (adjusted hazard ratio [per year] 0.92, 95% CI, 0.86-0.98, P =.016).

CONCLUSION

Among postmenopausal women, younger age was associated with increased frequency of prolapse recurrence by 12 months after native tissue repair.

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.

Hemoglobin A1c and Reoperation After Surgery for Stress Incontinence or Prolapse

IMPORTANCE

Few studies compare the link between hemogobin A1c (HbA1c) and urogynecologic surgical complications.

OBJECTIVE

The objective of this study was to determine the association between HbA1c and reoperation in women undergoing surgery for stress urinary incontinence (SUI) or pelvic organ prolapse (POP).

STUDY DESIGN

We performed 2 separate retrospective cohort analyses using Cerner's HealthFacts Database (750 hospitals; 519,000,000 patient encounters from January 1, 2010, to November 30, 2018). We included women undergoing surgery for (1) SUI or (2) apical POP by International Classification of Diseases coding who had HbA1c at the initial procedure. Each analysis compared those undergoing reoperation for complications or recurrence and those who did not. Multivariable logistic regression assessed the association between reoperation and HbA1c both as a continuous variable and comparing the commonly accepted cutoff ≥8.

RESULTS

Of 30,180 SUI surgical procedures and 26,389 POP surgical procedures, 1,625 (5.4%) and 805 (3.1%) had HbA1c. Median (interquartile range) HbA1c in grams per deciliter was similar by reoperation status (SUI: 6.0 [5.6-6.8] vs 6.1 [5.6-6.9], P = 0.35; POP: 6.2 [5.6-6.6] vs 6.1 [5.7-6.8], P = 0.60). Reoperation was also similar using the HbA1c ≥8% cutoff (SUI: 6.9% vs 7.4%, P = 0.79; POP: 6.3% vs 5.4%, P = 0.77). On multivariate analysis, HbA1c value was not a significant predictor of reoperation either as a continuous (SUI: odds ratio [OR] = 0.966, 95% CI = 0.833-1.119; POP: OR = 1.040, 95% CI = 0.801-1.350) or dichotomous variable ≥8 (SUI: OR = 0.767, 95% CI = 0.407-1.446; POP: OR = 0.988, 95% CI = 0.331-2.951). Mean follow-up was 4.28-5.13 years.

CONCLUSION

Although other studies have shown a link between diabetes and complications, we were unable to show an association between HbA1c values and rates of reoperation.

[Radiological imaging following pelvic prolapse surgery]

CLINICAL/METHODICAL ISSUE

Pelvic organ prolapse is a common condition in women, for which both conservative and surgical interventions are available. Knowledge of the different surgical procedures and the materials used is essential for adequate radiological diagnosis after prolapse surgery in order to differentiate potential complications from normal postoperative changes.

STANDARD RADIOLOGICAL METHODS

In the immediate postoperative period, computed tomography (CT) is often the modality of choice for evaluating acute complications such as bleeding or organ injuries. Magnetic resonance imaging (MRI) provides excellent soft tissue contrast and is therefore generally preferred for assessing subacute and chronic complications.

METHODICAL INNOVATIONS

Innovative techniques such as dynamic MRI protocols can improve the radiological assessment after prolapse surgery by enabling the evaluation of organ mobility.

PERFORMANCE

Radiological standard procedures such as computed tomography (CT) and MRI provide detailed and reliable information about the postoperative site and potential complications following prolapse surgery.

ACHIEVEMENTS

Radiological imaging plays an important role in the evaluation of patients after prolapse surgery, particularly when complications are suspected. Accurate radiological diagnosis can guide further appropriate therapeutic measures.

Outcomes of robotic sacrocolpopexy

This review aimed to summarize the complications and surgical outcomes of robot-assisted sacrocolpopexy. Nineteen original articles on 1,440 robotic sacrocolpopexies were reviewed, and three systematic reviews and meta-analyses were summarized in terms of intraoperative, perioperative, postoperative, and/or surgical outcomes. Robotic sacrocolpopexy has demonstrated low overall complication rates and favorable surgical outcomes. Nevertheless, long-term follow-up outcomes regarding objective and/or subjective prolapse recurrence, reoperation rates, and mesh-related complications remain unclear. Further research is required to demonstrate whether the robotic approach for sacrocolpopexy is feasible or can become the modality of choice in the future when performing sacrocolpopexy.

Clinical, anatomical and perioperative outcomes of abdominal sacral colpopexy using autologous fascia: A systematic review of the literature

OBJECTIVES

Although sacral colpopexy is considered the gold standard for the treatment of advanced apical prolapse, several warnings and restrictions has been delivered to urogynecological surgeons in order to avoid the implants of prosthetics meshes. The purpose of this systematic review is to investigate the role of sacral colpopexy performed with autologous tissue in literature.

METHODS

a systematic review according to PRISMA guidelines was performed in June 2022 through the Medline, Web of Science and Scopus databases. Quality assessment of each article was performed according to Critical Appraisal tool of Oxford center for EBM, LoE according to SORT standards, ROBINS-I tool for methodological assessment in non-randomized trials. From 236 screened records, 7 articles were considered eligible for this systematic review.

RESULTS

Collected data showed objective cure rate ranging from 94.7% to 100% in medium term follow up. Subjective cure rate was specifically investigated in 2 studies with high satisfaction rates. Complication rate ranged from 0 to 36.8%, with 90.1% graded ≤2 according to Clavien-Dindo classification.

CONCLUSIONS

sacral colpopexy with autologous fascia shows satisfying outcomes in terms of safety and efficacy and may be taken in account in particular clinical situations.

Comparative anatomy of the ovine and human pelvis for laparoscopic sacrocolpopexy: evaluating the effectiveness of the ovine model

INTRODUCTION AND HYPOTHESIS

Laparoscopic sacrocolpopexy (LSC) is a functional reconstructive surgery used to treat pelvic organ prolapse (POP) in middle-aged women. Although LSC is widely used, its implementation is hindered by perceived technical difficulties and surgical learning curves. Surgeons require adequate experience with LSC prior to performing the procedure on patients to improve their quality of life. This study is aimed at demonstrating the effectiveness of the ovine model (OM) for training and research in LSC, while also comparing anatomical differences between ovine and human models during the procedure.

METHODS

The animal model and training were provided by the Jesús Usón Minimally Invasive Surgery Centre. Urologists and gynecologists with experience in LSC participated in a course and their findings were recorded and documented.

RESULTS

Differences in patient positioning, trocar placement, and reperitonealization were identified between the ovine and human models. Hysterectomy is always performed in the ovine model, whereas it is not mandatory in humans. There are also differences in the dissection of the levator ani muscle and attachment point of the posterior mesh to the uterus between the two models. Despite differences in some areas, the ovine pelvic structure and vagina are similar in size to those of humans.

CONCLUSIONS

The ovine model is a valuable tool for surgeons in their learning curve for LSC, allowing for safe and effective practice prior to performing the procedure on patients. The use of the OM can help to improve the quality of life for women affected by pelvic organ prolapse.

Statewide geographic variation in hysterectomy approach for pelvic organ prolapse: a county-level analysis

BACKGROUND

There are no definitive guidelines for surgical treatment of pelvic organ prolapse. Previous data suggests geographic variation in apical repair rates in health systems throughout the United States. Such variation can reflect lack of standardized treatment pathways. An additional area of variation for pelvic organ prolapse repair may be hysterectomy approach which could not only influence concurrent repair procedures, but also healthcare utilization.

OBJECTIVE

This study aimed to examine statewide geographic variation in surgical approach of hysterectomy for prolapse repair and concurrent use of colporrhaphy and colpopexy.

STUDY DESIGN

We conducted a retrospective analysis of Blue Cross Blue Shield, Medicare, and Medicaid fee-for-service insurance claims for hysterectomies performed for prolapse in Michigan between October 2015 and December 2021. Prolapse was identified with International Classification of Disease Tenth Revision codes. The primary outcome was variation in surgical approach for hysterectomy as determined by Current Procedural Terminology code (vaginal, laparoscopic, laparoscopic assisted vaginal, or abdominal) on a county level. Patient home address zip codes were used to determine county of residence. A hierarchical multivariable logistic regression model with vaginal approach as the dependent variable and county-level random effects was estimated. Patient attributes, including age, comorbidities (diabetes mellitus, chronic obstructive pulmonary disease, congestive heart failure, morbid obesity), concurrent gynecologic diagnoses, health insurance type, and social vulnerability index were used as fixed-effects. To estimate variation between counties in vaginal hysterectomy rates, a median odds ratio was calculated.

RESULTS

There were 6974 hysterectomies for prolapse representing 78 total counties that met eligibility criteria. Of these, 2865 (41.1%) underwent vaginal hysterectomy, 1119 (16.0%) underwent laparoscopic assisted vaginal hysterectomy, and 2990 (42.9%) underwent laparoscopic hysterectomy. The proportion of vaginal hysterectomy across 78 counties ranged from 5.8% to 86.8%. The median odds ratio was 1.86 (95% credible interval, 1.33-3.83), consistent with a high level of variation. Thirty-seven counties were considered statistical outliers because the observed proportion of vaginal hysterectomy was outside the predicted range (as defined by confidence intervals of the funnel plot). Vaginal hysterectomy was associated with higher rates of concurrent colporrhaphy than laparoscopic assisted vaginal hysterectomy or laparoscopic hysterectomy (88.5% vs 65.6% vs 41.1%, respectively; P<.001) and lower rates of concurrent colpopexy (45.7% vs 51.7% vs 80.1%, respectively; P<.001).

CONCLUSION

This statewide analysis reveals a significant level of variation in the surgical approach for hysterectomies performed for prolapse. The variation in surgical approach for hysterectomy may help account for high rates of variation in concurrent procedures, especially apical suspension procedures. These data highlight how geographic location may influence the surgical procedures a patient undergoes for uterine prolapse.

Perioperative Vaginal Estrogen as Adjunct to Native Tissue Vaginal Apical Prolapse Repair: A Randomized Clinical Trial

Importance

Surgical repairs of apical/uterovaginal prolapse are commonly performed using native tissue pelvic ligaments as the point of attachment for the vaginal cuff after a hysterectomy. Clinicians may recommend vaginal estrogen in an effort to reduce prolapse recurrence, but the effects of intravaginal estrogen on surgical prolapse management are uncertain.

Objective

To compare the efficacy of perioperative vaginal estrogen vs placebo cream on prolapse recurrence following native tissue surgical prolapse repair.

Design, Setting, and Participants

This randomized superiority clinical trial was conducted at 3 tertiary US clinical sites (Texas, Alabama, Rhode Island). Postmenopausal women (N = 206) with bothersome anterior and apical vaginal prolapse interested in surgical repair were enrolled in urogynecology clinics between December 2016 and February 2020.

Interventions

The intervention was 1 g of conjugated estrogen cream (0.625 mg/g) or placebo, inserted vaginally nightly for 2 weeks and then twice weekly to complete at least 5 weeks of application preoperatively; this continued twice weekly for 12 months postoperatively. Participants underwent a vaginal hysterectomy (if uterus present) and standardized apical fixation (either uterosacral or sacrospinous ligament fixation).

Main Outcomes and Measures

The primary outcome was time to failure of prolapse repair by 12 months after surgery defined by at least 1 of the following 3 outcomes: anatomical/objective prolapse of the anterior or posterior walls beyond the hymen or the apex descending more than one-third of the vaginal length, subjective vaginal bulge symptoms, or repeated prolapse treatment. Secondary outcomes included measures of urinary and sexual function, symptoms and signs of urogenital atrophy, and adverse events.

Results

Of 206 postmenopausal women, 199 were randomized and 186 underwent surgery. The mean (SD) age of participants was 65 (6.7) years. The primary outcome was not significantly different for women receiving vaginal estrogen vs placebo through 12 months: 12-month failure incidence of 19% (n = 20) for vaginal estrogen vs 9% (n = 10) for placebo (adjusted hazard ratio, 1.97 [95% CI, 0.92-4.22]), with the anatomic recurrence component being most common, rather than vaginal bulge symptoms or prolapse repeated treatment. Masked surgeon assessment of vaginal tissue quality and estrogenization was significantly better in the vaginal estrogen group at the time of the operation. In the subset of participants with at least moderately bothersome vaginal atrophy symptoms at baseline (n = 109), the vaginal atrophy score for most bothersome symptom was significantly better at 12 months with vaginal estrogen.

Conclusions and Relevance

Adjunctive perioperative vaginal estrogen application did not improve surgical success rates after native tissue transvaginal prolapse repair.

Laparoscopic sacrocolpopexy mesh excision step-by-step

INTRODUCTION AND HYPOTHESIS

The objective was to demonstrate the surgical procedure of laparoscopic mesh removal after sacrocolpopexy to aid clinicians facing mesh complications.

METHODS

Video footage shows the laparoscopic management of mesh failure and mesh erosion after sacrocolpopexy with narrated video sequences of two patients.

RESULTS

Laparoscopic sacrocolpopexy represents the gold standard in advanced prolapse repair. Mesh complications occur infrequently but infections, failure of prolapse repair and mesh erosions necessitate mesh removal and repeat sacrocolpopexy if applicable. The video deals with two women referred to our tertiary referral urogynecology unit in the University Women's Hospital of Bern, Switzerland, after laparoscopic sacrocolpopexies that were carried out in remote hospitals. Both patients were asymptomatic more than 1 year after surgery.

CONCLUSIONS

Complete mesh removal after sacrocolpopexy and repeat prolapse surgery can be challenging but is feasible and is aimed at improving patients' complaints and symptoms.

Triple-compartment strategy for abdominal sacral colpopexy using PVDF mesh: one-year report of anatomical and subjective outcomes

INTRODUCTION AND HYPOTHESIS

Abdominal Sacral Colpopexy (ASC) is one of the best surgical methods to repair apical or uterine prolapse. We aimed to evaluate the short-term results of a triple-compartment open ASC strategy using polyvinylidene fluoride (PVDF) mesh in the treatment of patients with severe apical or uterine prolapse.

METHODS

Women with high-grade uterine or apical prolapse with or without cysto-rectocele were prospectively enrolled in the study from April 2015 to June 2021. We performed all-compartment repair using a tailored PVDF mesh for ASC. We assessed the severity of pelvic organ prolapse (POP) using the Pelvic Organ Prolapse Quantification (POP-Q) system at baseline and 12 months after the operation. The patients completed the International Continence Society Questionnaire Vaginal Symptom (ICIQ-VS) questionnaire at baseline, 3, 6, and 12 months postoperatively.

RESULTS

Thirty-five women with a mean age of 59.8±10.0 years were included in the final analysis. Stage III and stage IV prolapse was evident in 12 and 25 patients, respectively. After 12 months, the median POP-Q stage was significantly lower compared to the baseline (4 vs 0, p=<0.0001). Vaginal symptoms score was also reduced significantly at 3-month (7.5±3.5), 6-month (7.3±3.6), and 12-month (7.2±3.1) compared to the baseline (39.5±6.7) (p values < 0.0001). We did not observe any mesh extrusion or high-grade complications. Six (16.7%) patients had cystocele recurrence during the 12-month follow-up, and two of them needed reoperation.

CONCLUSIONS

Our short-term follow-up showed that using an open ASC technique with PVDF mesh in treating high-grade apical or uterine prolapse is associated with a high rate of procedural success and low rates of complication.

The impact of diabetes mellitus on pelvic organ prolapse recurrence after robotic sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

Data examining the effect of diabetes mellitus (DM) on prolapse recurrence after sacrocolpopexy (SCP) is limited. The primary objective of this study was to determine if DM affects prolapse recurrence after robotic SCP.

METHODS

This was a retrospective cohort study of women who underwent robotic SCP between 2012 and 2019 at Kaiser Permanente Southern California. The cohort was divided into women with and without DM at the time of SCP. The primary outcome was composite failure. Secondary outcomes included recurrent compartment-specific prolapse, reoperation rates, and surgical complications.

RESULTS

Of 547 patients included, 100 had DM. Women with DM were older, had higher BMI, higher parity, and were more likely to be nonwhite. Women with DM had more advanced prolapse at baseline but were not more likely to undergo concomitant procedures at the time of SCP. Over a median follow-up of 2.1 years (IQR 1.3, 3.4), women with DM had significantly increased risk of anterior vaginal prolapse (AVP) recurrence (13% vs 3%, p<0.01), but not composite failure (21% vs 14%, p=0.14). On multivariate regression, women with DM were almost 4 times as likely to experience AVP recurrence over time (AVP hazard ratio (HR) 3.93, 95% CI 1.29-12.03, p=0.02).

CONCLUSION

In our cohort, DM was a risk factor for AVP recurrence but not composite failure after robotic SCP.

The Outcome of Sacrocolpopexy/Sacrohysteropexy for Patients with Pelvic Organ Prolapse and Predictors of Anatomical Failure

Background

Pelvic organ prolapse (POP) is a medical condition that profoundly impacts women's quality of life. Unfortunately, the literature lacks long-term predictors and risk factors for its recurrence. This study aims to assess the efficacy and safety of Sacrocolpopexy/Sacrohysteropexy and to identify the predictors of recurrence in a Saudi setting.

Methods

In a retrospective cohort study, all patients who underwent Sacrocolpopexy (n=144) and Sacrohysteropexy (n=56) between 2009-2021 were followed up. Electronic medical records were examined to collect data on the following: Patient characteristics [age, parity, BMI, and past medical and surgical history], prolapse-related characteristics/symptoms, Surgery-related characteristics [type and approach of surgery, mesh type, and concomitant surgery], and Outcome characteristics. Postoperative anatomical success and failure rates were determined according to the Baden-Walker classification. Logistic regression analysis was applied to identify the predictors of overall anatomical failure of Sacrocolpopexy. Significance was considered at p<0.05.

Results

Success rates of 96.8%, 99.4%, and 85.2% were detected in the anterior, apical, and posterior vaginal prolapse, respectively, with an overall success rate of 83.1%. The overall failure rate was 15.9%, with an incidence density of 5.98 per 100 women-years. The onset of failure in 27 failure cases ranged from 40 days to 11.5 years postoperative. After adjustment for the possible potential confounders, older age (OR=1.06, 95% CI:1.01‒1.13, p=0.03) and the presence of diabetes (OR=4.93, 95% CI:1.33‒18.33, p=0.02) were the only significant predictors of operation failure. As for complications, six cases (3.6%) required reoperation, two cases (1.2%) had a bowel obstruction two and seven years after surgery, and one patient (0.6%) had vaginal mesh exposure.

Conclusion

The outcomes of Sacrocolpopexy/Sacrohysteropexy in our study are comparable to those in previous studies. Diabetes and elder age at the time of the surgery played a role in predicting recurrence. Sacrocolpopexy has a long-term profile of safety and efficacy. These findings could be key to stratifying surgical plans for pelvic organ prolapse cases.

Interactions between genetic variants and environmental risk factors are associated with the severity of pelvic organ prolapse

OBJECTIVE

Both environmental and genetic risk factors contribute to pelvic organ prolapse (POP). No genome-wide study has investigated the gene-environment (G × E) interactions. In this study, we aim to identify single nucleotide polymorphisms (SNPs) that may interact with the potential environmental factors, maximum birth weight, and age in Chinese women.

METHODS

We recruited 576 women for phase 1 and 264 women for phase 2 with stages III and IV prolapse from six geographic regions of China. Genomic DNAs from blood samples were genotyped using Affymetrix Axiom Genome-Wide CHB1 Array of 640,674 SNPs for phase 1 and Illumina Infinium Asian Screening Array of 743,722 SNPs for phase 2. Meta-analysis was used to combine the two results. Interactions of genetic variants with maximum birth weight and age on POP severity were identified.

RESULTS

In phase 1, 502,283 SNPs in 523 women passed quality control and 450 women had complete POP-quantification measurements. In phase 2, 463,351 SNPs in 257 women passed quality control with complete POP-quantification measurements. Three SNPs rs76662748 ( WDR59 , Pmeta = 2.146 × 10 -8 ), rs149541061 ( 3p26.1 , Pmeta = 9.273 × 10 -9 ), and rs34503674 ( DOCK9 , Pmeta = 1.778 × 10 -9 ) respectively interacted with maximum birth weight, and two SNPs rs74065743 ( LINC01343 , Pmeta = 4.386 × 10 -8 ) and rs322376 ( NEURL1B - DUSP1 , Pmeta = 2.263 × 10 -8 ), respectively, interacted with age. The magnitude of disease severity associated with maximum birth weight and age differed according to genetic variants.

CONCLUSIONS

This study provided preliminary evidence that interactions between genetic variants and environmental risk factors are associated with POP severity, suggesting the potential use of combining epidemiologic exposure data with selected genotyping for risk assessment and patient stratification.
