A review of the current status of laparoscopic and robot-assisted sacrocolpopexy for pelvic organ prolapse

Improvement in Quality of Life after Laparoscopic or Robotic-assisted Sacrocolpopexy with a Single Anterior Mesh in Patients with Pelvic Organ Prolapse: A Retrospective Analysis from a Single Institution

Objectives

Pelvic organ prolapse (POP) is a significant health-care problem for older women. We have treated POP surgically using laparoscopic sacrocolpopexy (LSC) or robotic-assisted sacrocolpopexy (RSC). The original LSC and RSC procedures were done with anterior and posterior meshes; however, the use of the single mesh procedure is increasing because of its simplicity and safety. There have been few reports about the change in quality of life (QOL) using the single mesh procedure. Therefore, the present study aimed to retrospectively evaluate the change in QOL by LSC and RSC using a single anterior mesh for women without posterior compartment prolapse.

Materials and Methods

We performed LSC or RSC using a single anterior mesh in 52 patients who had POP without posterior vaginal wall prolapse between August 2018 and October 2022. We assessed the QOL before and after surgery using prolapse-QOL (P-QOL) questionnaires.

Results

All patients who received LSC or RSC with a single anterior mesh left the hospital as scheduled without severe perioperative complications. There were no instances of wound infection or vaginal mesh extrusion. The recovery rate of questionnaires was 63.5% (33/52). All QOL score domains improved significantly, and there were no questionnaire parameters that worsened.

Conclusion

LSC or RSC using only a single anterior mesh improves P-QOL with a low incidence of surgical complications for POP patients who did not have posterior vaginal wall prolapse. LSC or RSC with a single anterior mesh may be a prospective new procedure for POP.

Comparison of efficacy between laparoscopic pectopexy and laparoscopic high uterosacral ligament suspension in the treatment of apical prolapse-short term results

To compare the clinical efficacy of laparoscopic pectopexy and laparoscopic high uterosacral ligament suspension in women suffering from apical prolapse. The clinical data of 170 patients with apical prolapse (POP-Q score ≥ II) treated in the Third Affiliated Hospital of Zhengzhou University from January 2018 to July 2020 were retrospectively analyzed to assess the clinical efficacy of three surgical methods [laparoscopic pectopexy with uterine preservation, laparoscopic pectopexy with hysterectomy, laparoscopic high uterosacral ligament suspension (LHUSLS) with hysterectomy]. Patients were divided into three groups depending on Surgical methods: laparoscopic uterine pectopexy group (n = 23), laparoscopic pectopexy with hysterectomy group (n = 78) and LHUSLS with hysterectomy group (n = 69). The POP-Q points before and after operation were analyzed. The operation-related indices, perioperative periods and post-operative complications were compared. 1. The operation time of laparoscopic uterine pectopexy group was the shortest (p < 0.05). There was no significant difference in the incidence of apical prolapse and new stress urinary incontinence among the three groups during the follow-up period (p > 0.05). 2. The POP-Q points (Aa, Ba, C) in the three groups were better than those before operation (p < 0.05). Laparoscopic pectopexy with hysterectomy group had better Ap, Bp and C points and a longer TVL than LHUSLS with hysterectomy group (p < 0.05). 3. The postoperative PFDI-20, PFIQ-7 and PISQ-12 scores of the three groups were significantly improved than those before operation (p < 0.05). The PISQ-12 scores in laparoscopic uterine pectopexy group were significantly higher than that in the other two groups one year after operation (p < 0.05). The study concludes that laparoscopic pectopexy and LHUSLS can significantly improve the quality of life and sexual function for patients with apical prolapse. One year after operation, laparoscopic pectopexy has a more satisfactory anatomical reduction than LHUSLS with hysterectomy. The laparoscopic uterine pectopexy group had lower postoperative complications and better sexual function than that with hysterectomy group. Laparoscopic pectopexy should be used for the treatment of apical prolapse (POP-Q score ≥ II) patients who aim to better clinical efficacy and sexual function improvement.

Effectiveness of Laparoscopic Pectopexy for Pelvic Organ Prolapse Compared with Laparoscopic Sacrocolpopexy

STUDY OBJECTIVE

To evaluate the clinical benefits of laparoscopic pectopexy vs laparoscopic sacrocolpopexy in women with pelvic organ prolapse (POP).

DESIGN

Prospective cohort study.

SETTING

A tertiary hospital.

PATIENTS

We included 203 patients with POP.

INTERVENTIONS

Laparoscopic pectopexy or laparoscopic sacrocolpopexy.

MEASUREMENTS AND MAIN RESULTS

Anatomic effectiveness was measured using the POP Quantification system, both before and after operation. Functional recovery effectiveness was evaluated using complications and recurrence rates within 1 year. Quality of life was assessed by the Pelvic Floor Distress Inventory-20 and Incontinence Quality of Life questionnaires at enrollment and postoperative months 3, 6, and 12. Comparisons between groups were performed using t test, chi-square test, and mixed-effects model with repeated measures. The analysis included 203 eligible patients (sacrocolpopexy, 101; pectopexy, 102). The proportion of robotic-assisted surgeries was lower in the pectopexy group than in the sacrocolpopexy group (15.7% vs 41.6%, p <.001). The average operation time of pectopexy was shorter than that of sacrocolpopexy (174.2 vs 187.7 minutes) with a mean difference of 13.5 minutes (95% confidence interval, 3.9-23.0; p = .006). Differences of intraoperative blood loss, length of hospital stay, and postoperative 7-day complications between groups were not significant. Anatomic successes were obtained in both groups with similar improvement in POP Quantification scores. The rate of urinary symptoms recurrence was higher in the pectopexy group (13.7%) than in the sacrocolpopexy group (5.0%) at the 1-year follow-up (odds ratio, 3.1; 95% confidence interval, 1.1-8.8, p = .032). The Pelvic Floor Distress Inventory-20 and Incontinence Quality of Life scores were better improved at postoperative months 3, 6, and 12 for laparoscopic pectopexy than for sacrocolpopexy.

CONCLUSION

Laparoscopic pectopexy revealed comparable anatomic success, shorter operation time, and better improvement in quality of life scores of prolapse, colorectal-anal, and urinary symptoms at 1-year follow-up, possibly being an alternative when sacrocolpopexy is not practicable. However, clinicians should pay more attention to the recurrence of urinary symptoms after pectopexy.

Multimodality Imaging of Anterior Compartment Pelvic Floor Repair

Pelvic organ prolapse (POP) and stress urinary incontinence (SUI) are two common disorders that affect the anterior compartment of the pelvic floor in women. These can be treated conservatively or surgically. Among patients treated surgically, a substantial number present with pain, recurrent POP or SUI, or other conditions that warrant additional interventions. In many of these cases, imaging is key to identifying and characterizing the type of procedure performed, locating synthetic materials that may have been placed, and characterizing complications. Imaging may be particularly helpful when prior surgical records are not available or a comprehensive physical examination is not possible. US and MRI are the most commonly used modalities for such patients, although radiopaque surgical materials may be visible at voiding cystourethrography and CT. The authors summarize commonly used surgical treatment options for patients with SUI and POP, review imaging techniques for evaluation of such patients, and describe the normal imaging appearance and complications of pelvic floor surgical repair procedures in the anterior compartment of the pelvis. ©RSNA, 2023 Quiz questions for this article are available in the supplemental material.

Laparoscopic pectopexy with native tissue repair for pelvic organ prolapse

PURPOSE

The use of mesh for vaginal repair is currently problematic; consequently, there is increased interest in native tissue repair. Combining native tissue repair with sufficient mesh-applied apical repair might provide effective treatment. We describe the study focusing on the combination of pectopexy and native tissue repair.

METHODS

Between April 2020 and November 2021, 49 patients with symptomatic stage III or IV were treated with laparoscopic pectopexy combined with native tissue repair. The mesh was solely used for apical repair. All other clinically relevant defects were treated with native tissue repair. The perioperative parameters including surgical time, blood loss, hospital stay, and complications were recorded. The anatomical cure rate was evaluated according to the Pelvic Organ Prolapse Questionnaire (POP-Q) assessment. Validated questionnaires of the Pelvic Floor Distress Inventory (PFDI-20) and the Pelvic Floor Impact Questionnaire (PFIQ-7) were recorded to evaluate the symptom severity and quality of life.

RESULTS

The mean duration of follow-up was 15 months. All domains of POP-Q, PFDI-20, and PFIQ-7 scores improved significantly after surgery. No major complications, mesh exposure, or mesh complication occurred during the follow-up period.

CONCLUSION

The overall repair concept of laparoscopic pectopexy as the core, assisted by vaginal natural tissue repair for severe pelvic organ prolapse can achieve satisfactory clinical results and improve patient satisfaction.

Three-dimensional vs two-dimensional endoscopic approach in urogynecology: A retrospective cohort study of laparoscopic sacrocolpopexy

AIM

The gold standard to treat an apical pelvic organ prolapse is the abdominal route via a sacrocolpopexy, which is also reproduced by laparoscopic route. A laparoscopic sacrocolpopexy however, requires surgical expertise. Three-dimensional (3D) laparoscopy has been developed to overcome the lack of depth perception, that is a known disadvantage of conventional two-dimensional (2D) laparoscopy. This procedure can accelerate the learning curve and optimize the intra-, peri-, and postoperative outcomes. This study aims to compare 3D laparoscopy to traditional 2D laparoscopy for sacrocolpopexy.

METHODS

Data from 132 patients who underwent a sacrocolpopexy with 2D or 3D laparoscopy in Department of Obstetrics and Gynecology, University Medical Center of the Johannes Gutenberg University, between June 2012 and September 2021, were collected retrospectively. Seventy-one laparoscopic sacrocolpopexy operations in 2D (n = 23) and 3D (n = 48) group were reviewed and compared regarding the duration of surgery, blood loss and the length of hospital admission as primary objectives.

RESULTS

There were no differences in the baseline demographics between the two groups. The estimated blood loss (1.0 (±0.6) g/dL vs 1.7 (±1.0) g/dL, p = 0.010), and duration of surgery (115.4 (±34.7) min. vs 134.7 (±26.2) min., p = 0.012) was significantly better in favor of 3D laparoscopy. The length of hospital stay was comparable in both groups (p = 0.833). Furthermore, no differences were observed between the groups regarding other surgical outcomes.

CONCLUSION

3D laparoscopy shows a significant benefit in terms of estimated blood loss and surgery duration among complex urogynecological surgeries compared to traditional 2D laparoscopy.

Medium-term risk of recurrent pelvic organ prolapse within 2-year follow-up after laparoscopic sacrocolpopexy

Objective

The present study was performed to determine the risk of recurrent pelvic organ prolapse (POP) within 2 years after laparoscopic sacrocolpopexy (LSC) in patients with uterovaginal prolapse.

Materials and Methods

A retrospective comparative study was performed in a population of 204 patients over a 2-year follow-up period following LSC with concomitant supracervical hysterectomy or uterine preservation at a single urological clinic between 2015 and 2019. The primary outcome was surgical failure following LSC in cases of POP, focusing on failures occurring before the 2^ndyear of follow-up. Logistic regression analysis was used to determine the odds ratios (ORs) for surgical failure.

Results

The primary outcome, surgical failure in cases of POP, occurred 2 years after the initial surgery in 19 of the 204 patients (9.3%) (95% confidence interval [CI], 5.7% - 14.2%). Surgical failure was most common in the anterior compartment (n = 10, 4.9%), and further surgery was performed in seven of the patients with surgical failure (3.4%). The poor primary outcome was predicted by lysis of adhesions (OR, 7.5, 95% CI, 1.6-33.8, P = 0.008) and preoperative POP stage IV (OR, 3.5; 95% CI, 1.1-10.8, P = 0.03) on multivariable logistic regression analysis.

Conclusion

The overall rate of surgical failure following LSC in our cohort was 9.3% over the 2-year follow-up period after surgery, and preoperative prolapse stage IV was associated with a higher risk of recurrence.

"Every minute counts": association between operative time and post-operative complications for patients undergoing minimally invasive sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

Our aim was to assess whether operative time is independently associated with post-operative complications for minimally invasive sacrocolpopexy (MISCP).

METHODS

Using the National Surgical Quality Improvement Program (NSQIP) database, patients undergoing MISCP from 2015 to 2020 were identified by CPT code. The following data were extracted: demographics, concomitant procedures (hysterectomies, midurethral sling, and anterior or posterior repair), and post-operative complications. Complications were categorized into minor, major, and composite, modeled after the Clavien-Dindo classification. For analysis, covariates associated with operative time and composite complications were identified using a general linear model and Chi-squared or Fisher's exact test as appropriate. Then, adjusted spline regression was performed as a test of nonlinearity between operative time and composite complications. Adjusted relative risks of complications by 60-min increments were estimated using Poisson regression with robust error variance.

RESULTS

A total of 13,239 patients who underwent MISCP were analyzed. Overall, mean operative time (SD) was 189.5 (78.3) min. Post-operative complication rates were 2.6% for minor, 4.7% for major, and 7.3% for composite complications. Age, smoking, and sling were the only covariates associated with both operative time and post-operative complications. Adjusted spline regression demonstrated linearity (p<0.0001). With each 60-min increase in operative time, adjusted relative risks (95% CI) were 1.14 for composite (1.09, 1.19), 1.16 for minor (1.10, 1.21), and 1.11 (1.03, 1.20) for major complications.

CONCLUSIONS

Operative time is independently and linearly associated with post-operative complications for patients undergoing MISCP, even when adjusted for demographic variables and concomitant procedures.

Comparing Minimally Invasive Sacrocolpopexy With Vaginal Uterosacral Ligament Suspension: A Multicenter Retrospective Cohort Study Through the Fellows' Pelvic Research Network

IMPORTANCE

Comparing one-year surgical outcomes of two widely used surgical procedures for apical suspension.

OBJECTIVES

The objective of this study is to compare anatomic outcomes after minimally invasive sacrocolpopexy (MISC) and vaginal uterosacral ligament suspension (vUSLS).

STUDY DESIGN

This was a multicenter, retrospective cohort study through the Fellows' Pelvic Research Network. Patients with ≥ stage II pelvic organ prolapse (POP) who underwent MISC or vUSLS from January 2013 to January 2016, identified through the Current Procedural Terminology codes, with 1 year or longer postoperative data were included. Patients with prior POP surgery or history of connective tissue disorders were excluded. Anatomic success was defined as Pelvic Organ Prolapse Quantification System measurements: Ba/Bp ≤ 0 or C ≤ -TVL/2. Data were compared using χ 2 or Fisher exact tests. Continuous data were compared using Wilcoxon rank sum test.

RESULTS

Three hundred thirty-seven patients underwent MISC (171 laparoscopic, 166 robotic) and 165 underwent vUSLS. The MISC group had longer operative time (205.9 minutes vs 187.5 minutes, P = 0.006) and lower blood loss (77.8 mL vs 187.4 mL; P < 0.001). Two patients (0.6%) in the MISC group had mesh exposure requiring surgical excision. Permanent suture exposure was higher after vUSLS (6.1%). At 1 year, anatomic success was comparable in the apical (322 [97%] MISC vs 160 [97%] vUSLS, P = 0.99) and posterior compartments (326 [97.6%] MISC vs 164 [99.4%] vUSLS; P = 0.28). Anterior compartment success was higher in the MISC group (328 [97.9%] vs 156 [94.9%], P = 0.04) along with longer total vaginal length (9.2 ± 1.8 vs 8.4 ± 1.5, P < 0.001).

CONCLUSION

At 1 year, patients who underwent MISC or vUSLS had similar apical support. Low rates of mesh and suture exposures, less anterior recurrence, and longer TVL were noted after MISC.

Chronic Pelvic Pain, Quality of Life, and Patient Satisfaction After Robotic Sacrocolpopexy for Pelvic Organ Prolapse

Background and objective

When evaluating repair outcomes in robotic sacrocolpopexy (RSC) for the treatment of pelvic organ prolapse (POP), it has become evident that surgeons usually focus on anatomical improvements and neglect equally important parameters of patient satisfaction and quality of life (QoL). Investigating these factors would aid in achieving a more patient-centered approach to treatment. This study aimed to examine QoL and satisfaction outcomes in women after RSC.

Methods

This study analyzed self-reported patient data regarding RSC for POP performed between October 2009 and February 2017 by fellowship-trained urologists in female pelvic medicine and reconstructive surgery. These patients participated in a survey to assess overall satisfaction and QoL, as well as contributing factors, such as changes in bladder and bowel function, vaginal bulge, and vaginal pain on a 7-point Likert scale (ranging from markedly worse to markedly improved). Data were examined using multivariate regression analysis. Positive treatment response was defined as scores of 6 or 7, whereas negative response was defined as scores of 1 to 5.

Results

The response rate was 41% (156/380), and the median age of the participants was 70 years [interquartile range (IQR): 63, 73]. Of note, 98.7% were Caucasian, with 73% currently in a significant relationship. The median duration since RSC was 2.12 years (IQR: 1.2, 3.7). Overall, 93 (66.9%), patients (23.0%), and 123 patients (88.5%) had a positive treatment response for bladder function, bowel function, and vaginal bulge, respectively. Furthermore, 66% of women had improved QoL, 84% reported improved overall satisfaction, and 91.4% stated that they would recommend RSC to a friend. After controlling for significant covariates, results of a multivariate analysis demonstrated positive treatment response for bladder function [odds ratio (OR): 14.6; p < 0.0001], bowel function (OR: 9.72; p = 0.003), and vaginal bulge (OR: 41.7; p < 0.0001), significantly associated with increased odds of having improved QoL, whereas positive treatment response for vaginal bulge (OR: 26.9; p = 0.023) and recommending RSC to a friend (OR: 175; p = 0.0009) were associated with positive overall satisfaction.

Conclusions

Our findings endorse using RSC surgery for patients with POP based on both QoL improvement and overall post-procedure satisfaction perspective. This study may help encourage surgeons and clinicians to employ a surgical modality that incorporates each patient’s unique treatment desires and goals and provide patients with realistic post-procedure goals and expectations regarding treatment.

A preliminary clinical report of transvaginal natural orifice transluminal endoscopic Sacrospinous Ligament Fixation in the treatment of moderate and severe pelvic organ prolapse

Objective

To study the efficacy and safety of transvaginal natural orifice transluminal endoscopic Sacrospinous Ligament Fixation in the treatment of moderate and severe pelvic organ prolapse.

Design

Patients were selected into this study on a voluntary basis to evaluate the short-term efficacy of this surgery by comparing the OP-Q scores before the operation, three months after the operation, and six months after the operation.

Setting and Patients

Evaluate the clinical efficacy and safety by a retrospective analysis of the clinical data of the 18 patients with POP-Q grade III–IV pelvic organ prolapse treated by the Department of Gynecology of Nanjing Medical University Affiliated Changzhou No.2 People's Hospital from April 2020 to November 2020, and their post-operation follow-ups.

Interventions

Patients with postoperative follow-ups found no obvious relapse without intervention measures.

Measurements and Main Results

The transvaginal natural orifice transluminal endoscopic Sacrospinous Ligament Fixation was performed successfully, and the anterior and posterior walls of vagina and/or trans-vaginal hysterectomy were repaired as appropriate. Except the total vaginal length (TVL), the P values of numerical analysis for all points before, three months after, and six months after the operation were all <0.05, being statistically significant.

Conclusion

This method is effective in the treatment of moderate and severe pelvic organ prolapse with few complications, but more cases and longer-term follow-up data are needed to determine the long-term effect of this procedure. For the selection of puncture sites, more anatomical data are needed to get more accurate result.

Laparoscopic Lateral Suspension (LLS) for the Treatment of Apical Prolapse: A New Gold Standard?

Nowadays, the gold standard to treat apical pelvic organ prolapse (POP) is laparoscopic sacrocolpopexy (LSCP). However, LSCP is a difficult procedure associated with rare but potentially severe complications. Promontory dissection may expose to potential life-threatening intraoperative vascular injuries, and sacral roots or hypogastric nerve damage. There are also a few case reports of spondylodiscitis with consecutive lumbar vertebra bone erosion. Laparoscopic lateral suspension (LLS) with mesh is an alternative technique for apical POP repair. It lowers perioperative risks by avoiding sacral promontory preparation. Recent studies show similar anatomical and functional outcomes to LSCP, with the advantage of better preserving the vaginal axis. Moreover, LLS is well suited for hysteropexy which is important as an increasing number of women prefer uterine preservation during POP surgery. In this article, we discuss both techniques, and we share our opinion on a novel perspective in the treatment of apical POP with uterine preservation.

Surgical Complications and Hospital Costs in Robot-Assisted Versus Conventional Laparoscopic Hysterectomy With Concurrent Sacrocolpopexy: Analysis of the Nationwide Readmissions Database

OBJECTIVES

Despite increasing use of robotic technology for minimally invasive hysterectomy with sacrocolpopexy, evidence supporting the benefits of these costly procedures remains inconclusive. This study aimed to compare differences in perioperative complications, 30-day readmissions, and costs between robot-assisted and conventional laparoscopic hysterectomy with concurrent sacrocolpopexy using a large national database.

METHODS

Using the 2009-2015 Nationwide Readmissions Database and procedure codes, we identified patients who underwent a robot-assisted or conventional laparoscopic hysterectomy with sacrocolpopexy. We measured in-hospital perioperative complications using diagnosis and procedure codes and measured 30-day readmissions based on patient linkages across hospitalizations. Hospital costs were estimated using charges and cost-to-charge ratios. These outcomes were compared between robot-assisted and conventional laparoscopic procedures using bivariate and multivariable regression analysis.

RESULTS

Our weighted sample included a total of 7,675 patients. Major perioperative complications occurred in 6.7% of robot-assisted and 11.2% of conventional laparoscopic procedures (unadjusted P < 0.001; adjusted odds ratio, 0.69; 95% confidence interval, 0.51-0.93; P = 0.02). Hospital costs were higher in robot-assisted than in conventional laparoscopic procedures (respective median costs, $16,367 vs $13,898; P < 0.001), with an adjusted cost ratio of 1.24 (95% confidence interval, 1.17-1.31; P < 0.001). The risk of 30-day readmission was similar between robot-assisted and conventional laparoscopic procedures.

CONCLUSIONS

Nationally representative data suggest that, in laparoscopic hysterectomy with sacrocolpopexy, the robot-assisted approach is associated with a lower risk of perioperative complications, despite higher costs, compared with the conventional one. The risk of 30-day readmission was similar between the robot-assisted and conventional laparoscopic approaches.

Technical features, perioperative and anatomical outcomes of a standardized suturing pattern for robotic sacrocolpopexy

INTRODUCTION AND HYPOTHESIS

Several technical alternatives to repair mesh using laparoscopic sacrocolpopexy exist. We aim to describe the outcomes and surgical technique of robotic-assisted colpo-/cervicosacropexy using a standardized suturing scheme to repair the mesh.

METHODS

We retrospectively reported data of 60 consecutive cases of robotic-assisted colpo-/cervicosacropexy for advanced multicompartmental prolapse using a standardized suturing design. We placed three non-absorbable stitches on the cervix or three absorbable stitches on the apex of the vaginal vault, six long-term absorbable stitches on the anterior vaginal wall deep to the basis of the vesical trigone, six similar posterior stitches with the deeper row of sutures down to the levator ani plane and three non-absorbable stitches on the sacral promontory as the cranial support for Y-shaped polypropylene mesh.

RESULTS

Median operative time was 188 ± 43 min. All the procedures were successfully performed using a Da Vinci Si platform in a three-arm configuration, and no conversion to open or traditional laparoscopic surgery was needed. The length of hospital stay was 1.2 ± 1.7 days, and no readmission within 30 postoperative days was reported. At a follow-up of 12 and 24 months, no case of extrusion or exposure of the mesh occurred, and the retreatment rate was 6.7%.

CONCLUSIONS

Our suturing technique is safe and effective, with negligible risk of complications and good medium-term results. It is plausible that robotic systems may facilitate precise, accurate and reproducible placement of the stitches, thereby favoring wider diffusion of minimally invasive treatment of advanced prolapse.

A biomechanical analysis of different meshes for reconstructions of the pelvic floor in the porcine model

Purpose

Many different surgical approaches have been established for the repair of a pelvic organ prolapse. Especially in laparoscopic surgery, it is important to generate easy surgical techniques with similar stability. This study shall simplify the choice of mesh by evaluating three polypropylene meshes regarding their biomechanical properties.

Methods

Biomechanical testing was performed in the porcine model. The meshes are fixated on porcine fresh cadaver cervices after subtotal hysterectomy. The apical part of the mesh is fixated with parallel screw clamps at the testing frame. Forty-one trials were performed overall, subdivided into four subgroups. The groups differ in mesh type and fixation method. Maximum load, displacement at failure and stiffness parameters were evaluated with an Instron 5565^® test frame.

Results

SERATEX^® E11 PA (E11) showed the highest values for maximum load (199 ± 29N), failure displacement (71 ± 12 mm) and stiffness (3.93 ± 0.59 N/mm). There was no significant difference in all three evaluated parameters between SERATEX^® B3 PA (B3) and SERATEX^® SlimSling^® with bilateral fixation (SSB). SERATEX^® SlimSling^® with unilateral fixation (SSU) had the lowest stiffness (0.91 ± 0.19 N/mm) and maximum load (30 ± 2 N) but no significant difference in displacement at failure.

Conclusion

All meshes achieved a good tensile strength, but the results of maximum load show that the E11 is superior to the other meshes. Through a bilateral fixation of SERATEX^® SlimSling^®, a simple operating method is generated without a loss of stability.

Laparoscopic sacrocolpopexy for pelvic organ prolapse: Comparison of standard versus tacker combination method

OBJECTIVE

To compare the surgical outcomes of laparoscopic sacrocolpopexy for pelvic organ prolapse between a group in which only sutures were used (standard method), and a group in which a combination of tackers and sutures were used (tacker combination method).

METHODS

A total of 77 patients who underwent laparoscopic sacrocolpopexys from June 2016 to October 2019 were divided into a suture group (36 patients) and a suture + tacker group (41 patients). We retrospectively compared operation time, amount of blood loss, postoperative length of hospital stay, incidence of perioperative complications and anatomical cure rate 1 year after surgery. Lower urinary tract symptoms were evaluated using symptom questionnaires and objective parameters.

RESULTS

Operation time in the suture + tacker group was shorter (104.9 ± 27.0 vs 147.5 ± 33.7 min; P < 0.0001). The incidence of perioperative complications in the suture group and the suture + tacker group was 2.8% and 2.4%, respectively (P = 0.9409). Anatomical cure rates at 1 year after surgery were 94.4% and 100%, respectively (P = 0.2153). Both groups showed significant improvement after 1 year for International Prostate Symptom Score total and quality of life score, Overactive Bladder Symptom Score total score, voided volume, maximum urinary flow rate and post-void residual. [Corrections added on 7 September 2021 after first online publication: the first two P-values have been updated.] CONCLUSIONS: The combined use of sutures and tackers in laparoscopic sacrocolpopexy simplifies the procedure and translates into shorter operation time. Surgical outcomes at 1 year and improvement of lower urinary tract symptoms are similar regardless of the technique.

Suturing methods in prolapse surgery: a biomechanical analysis

INTRODUCTION

Pelvic organ prolapse is a common problem in urogynecological surgery. Abdominal and laparoscopic sacrocolpopexy is currently considered to be the gold standard of treatment. The main problem remains the anatomical point of fixation as well as how sutures are placed. We evaluated the biomechanical difference between an in-line ligament suture versus an orthogonal ligament suture and a single suture versus a continuous suture at the anterior longitudinal ligament in an in-vitro, sacrocolpopexy model.

METHODS

Biomechanical in-vitro testing was performed on human, non-embalmed, female cadaver pelvises. An Instron test frame (tensinometer) was used for load/ displacement analysis. The average patient age was 75 years. Ligament preparation yielded 15 ligaments available for testing. Recorded parameters were the ultimate load, failure displacement, and stiffness.

RESULTS

This in-vitro analysis of different suturing methods showed the difference between an orthogonal and an in-line approach to be the ultimate load. Orthogonal sutures displayed an ultimate load of 80 N while in-line suturing yielded only 57 N (p < 0.05). For the anterior longitudinal ligament, this study demonstrated that continuous suture is significantly superior to a single suture regarding failure displacement (p < 0.05).

CONCLUSION

We established baseline biomechanical parameters for the sacrospinous ligament and anterior longitudinal ligament. An orthogonal suture is superior to an in-line suture in an in-vitro model. A continuous suture is superior to a single suture at the anterior longitudinal ligament. Clinical trials might be able to evaluate whether any clinical significance can be established from these findings.

New "Wrinkle Method" for Intracorporeal Anterior Vaginal Wall Plication during Sacrocolpopexy

In this study, we introduce a new wrinkle method for intracorporeal anterior vaginal wall plication during sacrocolpopexy for pelvic organ prolapse (POP) aiming to decrease POP recurrence and postoperative vaginal wall mesh erosion. The wrinkle method was performed using robotic sacrocolpopexy (RSC) on 57 symptomatic POP patients. Sixty-six patients underwent conventional RSC before the development of the wrinkle method. Feasibility and perioperative outcomes were compared. The wrinkle method is not time consuming. The total operative time was shorter in the wrinkle group than in the non-wrinkle group; however, this was attributed to lower adhesiolysis in the wrinkle group. No differences were recorded in the mean estimated blood loss and complication rates between the two groups. In conclusion, although we were unable to confirm that the wrinkle method decreased POP recurrence and vaginal wall mesh erosion after RSC because of the short follow-up period, our preliminary findings are positive in terms of safety. Further long-term well designed randomized controlled trials are required to elucidate the benefits of the wrinkle method.

Meshy business: MRI and ultrasound evaluation of pelvic floor mesh and slings

Pelvic floor disorders are a complex set of conditions including but not limited to stress urinary incontinence and pelvic organ prolapse that generally affect older and multiparous women. Of the several surgical options available for treatment of these conditions, synthetic mid-urethral slings for stress urinary incontinence and vaginal mesh for pelvic organ prolapse are amenable to imaging evaluation by ultrasound and magnetic resonance imaging techniques. Ultrasound can evaluate the sub- and immediate peri-urethral portions of sling due to its ability to differentiate synthetic material from native tissues with real-time imaging, while MRI is able to better depict the global pelvic floor anatomy and assess the more distant components of mesh and slings material. Given the high prevalence of pelvic floor disorders and complications after surgical repair, it is important that radiologists familiarize themselves with normal and abnormal imaging findings after these procedures. This article provides a review of the spectrum of imaging findings in patients after pelvic floor repair with synthetic mid-urethral slings and vaginal mesh.

Robotic and laparoscopic sacrocolpopexy for pelvic organ prolapse: a systematic review and meta-analysis

Background

Sacrocolpopexy is the gold standard procedure for treating pelvic organ prolapse (POP) patients with apical defects. Different surgical approaches have emerged and been utilized successively, including traditional laparoscopy, single-hole laparoscopy, robotic laparoscopy, vaginal-assisted laparoscopy, and transvaginal approaches. Robotic sacrocolpopexy (RSC) has attracted increasing attention as an emerging surgical technique and has unique advantages, such as a “simulated wrist” mechanical arm and high-definition three-dimensional (3D) visual field, which has gradually begun to be utilized in the clinical setting.

Methods

We followed the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) reporting checklist, and a systematic literature search was conducted on six databases from their inception to 1st March 2020. We evaluated patients with POP who underwent RSC or laparoscopic sacrocolpopexy (LSC), outcomes (including perioperative outcomes: blood loss, operating times, blood transfusion, and hospital stay), surgery-related complications, as well as cure and recurrence rates.

Results

A total of 49 articles were available, including 3,014 patients, among which 18 were comparative studies on LSC vs. RSC, and 31 were non-comparative single-arm studies on RSC. For RSC, median operative time was 226 [90–604] minutes, estimated blood loss was 56 [5–1,500] mL, and hospital stay was 1.55 [1–16] days. Intraoperative complications and postoperative complications occurred in 74 (2.7%) and 360 (13.0%) patients, respectively. Of 2,768 RSC patients, 40 had been converted from a robot-assisted approach to other approaches, and 134 of 1,852 patients (7.2%) have recurrent prolapses of any compartment. Compared to LSC, RSC was associated with significantly lower blood loss and lower conversion rate. However, more operative time was observed in RSC. No significant differences were observed in perioperative transfusion, intraoperative and postoperative complications, or objective recurrence between RSC and LSC.

Conclusions

RSC’s application seems to contribute some advantages compared to conventional laparoscopic surgery, although both approaches appear to promote equivalent clinical outcomes. Notably, heterogeneity among studies might have affected the outcome of the study. Consequently, high-quality and large-sample randomized trials comparing both techniques are necessitated.

It's not that mesh, is it? What providers should know about the transvaginal mesh controversy

The U.S. Food and Drug Administration recent ban on surgical mesh intended for the transvaginal repair of pelvic organ prolapse has called into question the safety of surgical mesh implants in general. As the media firestorm around vaginal mesh kits has continued to grow, important details about the specific type of mesh involved have been lost in the public discourse surrounding the controversy. This has left healthcare providers across the nation in the difficult position of addressing patient anxieties about the use of mesh in gynecologic surgery. This review seeks to educate women's health providers on the historical background and various uses of the different types of mesh in gynecologic surgery.

Outcomes of laparoscopic hysteropexy and supracervical hysterectomy plus cervicopexy: A retrospective study

Objectives:

The objective of this study is to compare the outcomes of laparoscopic hysteropexy (LHP) and laparoscopic supracervical hysterectomy plus cervicopexy (LSHCP) for the treatment of pelvic organ prolapse (POP).

Materials and Methods:

We retrospectively included patients who had undergone laparoscopic sacral hysteropexy or hysterectomy plus cervicopexy between January 2015 and May 2019 at Hualien Tzu Chi Hospital, Taiwan. Age at surgery, body mass index (BMI) at admission, the initial stage of genital prolapse, operative and postoperative data, and anatomical results were recorded. Cure for uterine prolapse was evaluated objectively through vaginal examinations using the POP quantification scale. Visual analog scale (VAS) scores were recorded at 24 h postoperatively. The Mann–Whitney U-test was used to compare continuous variables.

Results:

A total of 23 women were included in the study; 12 had received LHP (n = 12) and 11 had received LSHCP (n = 11). No differences existed in age, parity, BMI, blood loss, or hospital stay between groups. The difference in mean surgical times between the LHP and LSHCP groups was nonsignificant (154 and 176 min, respectively; P = 0.2). VAS scores were significantly lower in the LSHCP group than in the LHP group (0.1 vs. 1.75; P = 0.004). Furthermore, mean hospital stay was significantly longer in the LSHCP group than in the LHP group (4.0 vs. 3.1 days; P = 0.016). The procedure was successful in 100% of patients (23 of 23), with no objective evidence of uterine prolapse on examination at follow-up at 6 months.

Conclusion:

LHP had a significantly shorter hospital stay and a higher VAS score than LSHCP. LHP and LSHCP are both feasible and effective procedures for correcting uterine prolapse.

Laparoscopic sacrocolpopexy comparing polypropylene mesh with polyvinylidene fluoride mesh for pelvic organ prolapse: Technique description and long term outcomes

AIM

Our aim was to evaluate the feasibility and safety of laparoscopic sacrocolpopexy (LSCP) and compare the long-term outcomes and complication rates of polypropelene (PP) and polyvinylidene fluoride (PVDF), following up within a minimum of 12 months.

METHODS

This was a retrospective cohort study using patients who underwent LSCP for POP involving either PP or PVDF mesh between January 2011 and January 2018.

RESULTS

Our study focused on 172 women who underwent LSCP with mesh between January 2011 and January 2018. All procedures were successfully completed laparoscopically, and patients' baseline characteristics were not statistically different in the two groups. Between January 2011 and December 2014, we performed 82 cases of LSC, mainly using PP mesh. Over the last 5 years, since January 2015, we have used PVDF mesh for POP.

CONCLUSIONS

LSCP using PVDF mesh was found to provide excellent anatomical and functional outcomes after a median follow-up duration of 41 months, compared with the PP group, which had a median follow-up duration of 54 months. Mesh infection and erosion rates in the PP group were significantly higher than those in the PVDF group. Additionally, rates of vaginal pain and discomfort were significantly lower in the PVDF group when compared with the PP group.

Outcomes of nerve-sparing laparoscopic sacropexy on one hundred fifteen cases

STUDY OBJECTIVE

To evaluate the postoperative anatomic and functional outcomes of patients who underwent laparoscopic nerve-sparing sacrocolpopexy or sacrocervicopexy for pelvic organ prolapse (POP) POP-Q stage III and IV apical prolapse, and to delineate the contributing factors for recurrence.

STUDY DESIGN AND CLASSIFICATION

The file records of patients who underwent sacropexy in the last five years were reviewed retrospectively and compared in terms of preoperative and postoperative anatomic findings and symptoms.

PATIENTS

Patients who underwent laparoscopic nerve-sparing surgery for treatment of POP-Q Stage III and IV/prolapse of uterine or vaginal cuff were included.

INTERVENTIONS

Postoperative anatomic and functional outcomes were evaluated using POP-Q classification and urinary/anal function by questioning during visits.

RESULTS

The mean follow-up duration was 24.2 ± 17.6 months. Anatomic recovery was achieved in 104 (90.4 %) cases. Advanced age (≥70 years), longer duration of symptoms, and low body mass index were determined as parameters related to recurrence risk.

Risk of de novo posterior vaginal prolapse after anterior laparoscopic sacrocolpopexy: Evaluation at one year

INTRODUCTION AND HYPOTHESIS

Treatment of anterior vaginal and/or apical prolapse by sacrocolpopexy is most often performed by systematic placement of two non-resorbable meshes, anterior and posterior, whether or not there is an associated posterior vaginal prolapse. We believe that isolated correction of an anterior vaginal and/or apical prolapse in the absence of posterior vaginal prolapse is not associated with a higher rate of de novo posterior vaginal prolapse.

METHOD

A prospective, observational, monocenter study performed in the Gynecology unit of the Conception UHC in Marseille from May 2011 to October 2014. Patients over 18 years of age exhibiting an anterior vaginal and/or apical prolapse of stage ≥ 2 of the POP-Q classification resulting in functional impairment with alteration of the quality of life, without an associated posterior vaginal prolapse were included and underwent a laparoscopic anterior sacrocolpopexy (ASP). They were seen again in consultation one year from the intervention. Validated quality of life questionnaires were completed pre- and one year postoperatively.

RESULTS

50 patients were included. The rate of de novo posterior vaginal prolapse was 8/50 (16 %). At one year, there was a significant improvement in terms of the SPDI-20 and SPIQ-7 (p < 0.0001) questionnaire, without significant improvement in the quality of sexual function (PISQ-12 questionnaire) (p = 0.073).

CONCLUSION

The risk of de novo posterior vaginal prolapse at one year is low when an ASP is carried out.

One-year outcomes of a suture-less laparoscopic sacral hysteropexy using polypropylene Y-mesh grafts and fibrin sealant spray: A prospective comparative study

BACKGROUND

Laparoscopic sacral hysteropexy (SH) is a minimally invasive and effective treatment for uterovaginal prolapse in women who wish to retain the uterus. However, this procedure is limited by a steep learning curve and a long operating time. In this study, we aim to evaluate the surgical outcomes of a modified laparoscopic SH procedure using innovative methods of vaginal mesh attachment, which we hypothesized to be equally effective and time-saving.

METHODS

This was a prospective, parallel, comparative study conducted at a tertiary referral hospital. A total of 34 women with advanced (POPQ [Pelvic Organ Prolapse Quantification] stages ≧ 2) uterine prolapse, who underwent a laparoscopic SH procedure using lightweight polypropylene Y-mesh grafts (ALYTE), were studied. In half (n = 17) of the cases, fibrin sealant spray (TISSEEL) was applied to the meshes fixed at the anterior and posterior vaginal wall with fewer (six vs at least ten) sutures. A detailed comparison of one-year outcomes between groups was performed.

RESULTS

Patient characteristics and perioperative results were comparable between groups with the exception of a significantly shorter total operating time (247.0 vs 292.9 minutes, p = 0.04) noted in the fibrin group. At 1 year, anatomic success (POPQ stage ≦1) rates (76.5% vs 76.5%) were not different between groups. There were eight patients, with four in each group, who had surgical failure. Notably, most (7/8; 87.5%) surgical failures were at the anterior compartment (i.e, recurrent cystocele). No vaginal mesh extrusions were noted. After statistical analysis, we found "cystocele as the dominant prolapse before operation" was a significant predisposing factor for prolapse recurrence (p = 0.019; odds ratio = 8.04).

CONCLUSION

The modified laparoscopic SH procedure using Y-mesh grafts and fibrin sealant spray with fewer vaginal sutures was equally effective as conventional methods but saved time. Laparoscopic SH using Y-mesh grafts might not be as effective in repairing a concomitant dominant cystocele.

The current status of sacrocolpopexy in the management of apical prolapse

Pelvic organ prolapse (POP) is a prevalent condition that negatively affects women' s quality of life. There is growing recognition that adequate support for the vaginal apex is an important component of a durable surgical repair for women with advanced prolapse, including the anterior and posterior wall prolapse. Surgical treatment options include abdominal and vaginal approaches, the former of which can be performed open, laparoscopically, and robotically. Sacrocolpopexy is a common procedure designed for the treatment of prolapse including uterine or vaginal vault prolapse and multiple-compartment prolapse. Although traditionally performed as an open abdominal procedure, minimally invasive sacrocolpopexy, whether laparoscopic or robotic, has been successfully performed in the clinical practice by many pelvic reconstructive surgeons. In order to require an outstanding cosmetic result, transumbilical/transvaginal single-port sacrocolpopexy has been developed to achieve the goal and initial outcomes have demonstrated their efficacy, safety and feasibility. However, up to date, there are many variations to these procedures, with different levels of evidence to support each of them. Herein we reviewed the current literatures on current surgical choices for women with apical prolapse.

Laparoscopic sacral colpopexy for pelvic organ prolapse recurrence after transvaginal mesh surgery

OBJECTIVE

Pelvic organ prolapse (POP) recurrence in transvaginal mesh surgery patients has become increasingly common, due to widespread mesh use before the FDA alert. The aim was to assess feasibility, effectiveness and safety of laparoscopic sacral colpopexy (LSCP) in recurrent POP after previous vaginal surgery with polypropylene mesh.

STUDY DESIGN

Medical records of 20 patients with ≥ stage 2 POP recurrence, who underwent LSCP from January 2015 to July 2018, were retrospectively analyzed in a monocentric observational study. We analyzed operative time, intraoperative complications - defined as bowel, bladder, ureteral, or vascular injuries, post-operative complications - assessed with Clavien-Dindo's classification, and postoperative patient satisfaction - evaluated with the Patient Global Impression of Improvement questionnaire. Pre- and postoperative data were compared using t-test.

RESULTS

All women presented apical prolapse recurrence regardless of mesh type implanted and most of them involved the posterior compartment. No perioperative complications or cases of mesh extrusion, de novo urinary stress, urge incontinence, dyspareunia were recorded. At 12-month follow-up the POP-Q examinations demonstrated a statistically significant improvement of all parameters with a complete resolution of bulge, voiding and storage symptoms in all patients.

CONCLUSION

LSCP suggests safety, feasible and efficacy in the treatment of recurrent POP after prior transvaginal polypropylene mesh surgery. We suggest to conduct a prospective research with larger sample size to gain further insights.

Long-Term Assessment of a Prospective Cohort of Patients Undergoing Laparoscopic Sacrocolpopexy

OBJECTIVE

To report long-term outcomes after laparoscopic sacrocolpopexy.

METHODS

We conducted a prospective descriptive cohort study on 331 consecutive patients who underwent laparoscopic sacrocolpopexy for symptomatic prolapse (Pelvic Organ Prolapse Quantification [POP-Q] system stage 2 or greater) at one center, with minimum 1.5 years of follow-up by April 30, 2014. Primary outcome measures were Patient Global Impression of Change score and failure at the apex (C≥-1 cm; POP-Q stage 2 or greater). Secondary outcomes were anatomical failure in other compartments, duration of follow-up, occurrence and time point of complications, reinterventions, and functional outcomes by response to a standardized 24-question interview on prolapse and bladder, bowel, and sexual function. Assessment was by an experienced clinician not involved in patient management.

RESULTS

The follow-up rate was 84.6% (280/331); 185 of 331 (55.9%) patients were both physically examined and interviewed, and 95 of 331 (25.7%) were interviewed only. The median age at interview was 72 years (interquartile range 13 years), with a follow-up period of 85.5 months (interquartile range 46 months). Approximately 83% (231/280) reported improvement; 5.7% (16/280) were unchanged, 5.7% (16/280) felt slightly worse, and 6.8% (17/280) reported clear deterioration. Anatomical failure at point-C was 8.6% (16/185); anterior (22.2%, 41/185) and posterior (28.6%, 53/185) prolapse were more common than apical prolapse. Of those with level-I anatomical cure, 10.1% (17/185) felt worse; half of them (9/17) because of prolapse in another compartment. The others had urinary problems (41.2%, 7/17), obstructive defecation (11.8%, 2/17), or dyspareunia (11.8%, 2/17). Conversely, the majority of patients with recurrence at the vault (62.5%, 10/16) self-reported to be improved. The reoperation rate was 17.8% (48/270), including 19 (7.0%) for graft-related complications and nine (3.3%) for prolapse.

CONCLUSION

More than four out of five patients (82.5%) felt improved 86 months after laparoscopic sacrocolpopexy. Of those not improved, two thirds had recurrent prolapse; however, typically mid-vaginal. The other third reported urinary or bowel problems or dyspareunia. Reintervention for prolapse was 3.3%. The most common reasons for reoperation were graft-related complications (7.0%) and urinary incontinence (6.7%).

Robotic-assisted laparoscopic sacrocolpopexy: Initial Canadian experience

INTRODUCTION

Abdominal sacrocolpopexy provides effective long-term outcomes for apical pelvic organ prolapse. The introduction of robotic-assisted laparoscopic sacrocolpopexy (RALS) has mitigated the risks of abdominal surgery. This study aims to evaluate the preoperative patient characteristics, intraoperative surgical parameters, and postoperative outcomes of RALS, which has not been previously performed in Canada.

METHODS

A retrospective chart review of 47 patients who have undergone RALS from 2016-2018 by a single surgeon at a tertiary care hospital in Canada was completed.

RESULTS

This case series had a mean age of 60.2 years, body mass index (BMI) of 28.3 kg/m², and Charlson comorbidity index of 2.0. Preoperatively, 13 (28%), 23 (49%), and 11 (23%) patients had Baden-Walker grade 2, 3, and 4 apical prolapse, respectively. Intraoperatively, 45 (96%) patients underwent concomitant procedures, including 36 (77%) with adnexal surgery, 32 (68%) with anti-incontinence surgery, and 25 (53%) with hysterectomy. Intraoperative complications included one ureteric injury, two bladder injuries, and three vaginotomies. The mean robotic console time, surgery time, and total operating room times were 125.6, 148.6, and 190.6 minutes, respectively. Postoperatively, data was analyzed for 32 (68%) patients with greater than 12 weeks' followup. There was no recurrence of apical prolapse on exam after a mean followup of 60.1 weeks. Seven (22%) patients experienced symptomatic prolapse in the posterior compartment. There were two grade 3 Clavien-Dindo complications, including osteomyelitis and mesh exposure.

CONCLUSIONS

RALS can be safely and effectively performed with other pelvic procedures with good outcomes. Concurrent posterior repairs may be considered in select patients.

Iatrogenic endometriosis following apical pelvic organ prolapse surgery: a case report

BACKGROUND

Iatrogenic endometriosis is the presence of endometrial glands and stroma out of the uterus following certain surgical interventions. The rate of iatrogenic endometriosis after gynecologic surgeries due to benign uterine disease is 1-2%. Laparoscopic supracervical hysterectomy is also a part of frequently used surgical treatment of apical pelvic organ prolapse, which is followed by sacrocervicopexy. However, there are no data about iatrogenic endometriosis after apical prolapse surgery in the current literature. Herein, we present a case report of a patient diagnosed with de novo endometriosis 1 year after laparoscopic supracervical hysterectomy and sacrocervicopexy.

CASE PRESENTATION

A 46-year-old parous Slavic woman who underwent laparoscopic supracervical hysterectomy and sacrocervicopexy secondary to grade 3 symptomatic apical prolapse 1 year earlier was admitted to the same clinic with pelvic pain that had started 6 months following surgery. Deep vaginal palpation was painful. Transvaginal ultrasonography revealed an area with hypervascularization on the sacral promontory. She was scheduled for diagnostic laparoscopy. A 2 × 2-cm solid, wine-colored, hypervascular hemorrhagic lesion was seen on the sacral promontory. The lesion and the peritoneal layer behind it were totally excised. The patient was discharged on the first postoperative day, without any complications. Pathologic examination revealed foci of endometriosis comprising endometrial glands and stroma within the connective tissue, along with hemosiderin-laden macrophages. The symptoms of the patient resolved after the surgery, and no further adjuvant treatment was needed.

CONCLUSION

Although the rate of iatrogenic endometriosis is low after laparoscopic supracervical hysterectomy and sacrocervicopexy, the possibility of the occurrence of iatrogenic endometriosis should be discussed with patients who are diagnosed with apical prolapse to determine the type of surgical intervention. Iatrogenic endometriosis should be kept in mind for differential diagnosis in case of pain after laparoscopic supracervical hysterectomy and sacrocervicopexy.

The use of one-piece U-shaped mesh and barbed sutures in laparoscopic sacrocolpopexy

INTRODUCTION

Laparoscopic sacrocolpopexy (LS) is considered a safe and effective surgery for the treatment of pelvic organ prolapse (POP), but it requires expertise in laparoscopic surgery. The complexity of the intervention is due to the requirements of intracorporeal sutures and the manipulation of the mesh inside the cavity, which may be cumbersome. The barbed sutures (BS) simplify intracorporeal suturing and do not require knotting. Additionally, one-piece U-mesh (OP-UM) may facilitate handling, stabilization and tension adjustment. We describe our LS surgical technique using both materials to assess its feasibility, safety and effectiveness in a prospective series of patients.

MATERIALS AND METHODS

A total of 7 patients with symptomatic pelvic organ prolapse were included. Urogynecological history, classification of the pelvic organ prolapse according to Baden-Walker and the application of the Prolapse Quality of Life questionnaire were performed in all cases. The non-absorbable polypropylene OP-UM (Uplift ™) was used. The posterior side of the single sling is sutured to the elevator anus muscles with two non-absorbable stitches. Two strands of BS (V-Loc™), tied at their ends, were used to attach the mesh to the vagina in two lines of continuous sutures in opposite directions. Self-anchoring tackers were used for promontofixation and BS for peritoneal closure.

RESULTS

The median age was 60 years, the median time of the anterior branch mesh BS fixation was 23minutes (range 21,30 - 26,40min), intraoperative bleeding was minimal, and the median hospital stay was 3 days. No intraoperative complications were recorded, and no mesh erosions or recurrences were observed at a median follow-up of 14 months (range 3-25 months). All patients presented clinical improvement of the prolapse and were satisfied with surgery. We observed that the OP-UM self-stabilizes when it extends longitudinally into the abdominal cavity, reducing the need of the surgical assistant. The independent promontofixation of each part of the mesh (posterior and anterior) allows a more anatomical tension adjustment. Fixing the mesh to the vagina is fast and simple with our BS technique.

CONCLUSIONS

The use of OP-UM and BS during LS is feasible, safe, effective and could simplify this surgical technique.

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

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

Medium-term outcomes after robotic-assisted lateral suspension with mesh for advanced multi-compartmental prolapse

Introduction and hypothesis

Robotic abdominal lateral suspension (RALS) is an innovative mini-invasive surgical technique that allows treating apical and anterior prolapse. The safety and efficacy of this strategy have not yet been tested.

Methods

We completed a prospective case series of 115 RALS to treat apical and anterior prolapse stage III or IV, with no or minimal (stage I) posterior defect. Clinical evaluation was performed with a simplified POP quantification system (POP-Q). Mean follow-up was 28 ± 4 months. Primary outcomes were objective and subjective cure; secondary outcomes were reoperation rate for recurrence, erosion rate and complications. Objective cure was defined as POP-Q ≤ 1. Subjective cure was defined as absence of vaginal bulge. Patient’s satisfaction was measured using the Patient Global Impression of Improvement Scale (PGI-I).

Results

There was a significant improvement in POP-Q score in all treated compartments with an objective cure rate of 88.7% for the anterior and 93.1% for the apical compartment (p < 0.0001). Subjective cure rate was 82%. The emergence of de novo high rectoceles was not significant in the cohort, as much as the development of de novo stress or urge urinary incontinence. Reoperation rate for POP was 11.3% (8 recurrent cystoceles without apical descent and 5 apical and anterior relapses). No postoperative complications of Clavien-Dindo grade ≥ 3a were seen. Mesh exposure rate was 0.9%; 58.2% patients compiled a PGI-I score at 18–24 months post-surgery, reporting high satisfaction rates.

Conclusions

RALS is highly effective at a mid-term follow-up for the treatment of advanced apical and anterior POP.

Laparoscopic inguinal ligament suspension combined with hysterectomy for the treatment of uterovaginal prolapse

AIM

To demonstrate the efficacy and safety of a modified technique of laparoscopic inguinal ligament suspension (LILS) with hysterectomy for the treatment of uterovaginal prolapse.

METHODS

A total of 57 patients were treated by LILS combined with hysterectomy between Jan 2014 and Feb 2016. The perioperative parameters, such as operative time, estimated blood loss, length of stay and intra- and postoperative complications were recorded. The Pelvic Organ Prolapse questionnaire classification was applied to evaluate the Pelvic Organ Prolapse stage, and Patient Global Impression of Improvement scale was used to determine the patients' satisfaction. Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire were used to evaluate the functional improvement. All data were collected preoperatively and then at 12 months postoperatively.

RESULTS

The mean surgical time was 130.4 (82-190) min, the average blood loss was 50.4 (10-300) mL and the mean hospitalization was 5.3 (4-8) days. The rates of intra- and postoperative complications were low. After a minimal of 12 months follow-up, the anatomical success rate was 85.5%, and the subjective satisfaction rate was 92.7%. The functional measures also presented a significant improvement with no recurrence of prolapse.

CONCLUSION

LILS combined with hysterectomy was a safe and effective technique and might be considered as an alternative treatment for patients with uterovaginal prolapse.

Comparison between laparoscopic uterus/sacrocolpopexy and total pelvic floor reconstruction with vaginal mesh for the treatment of pelvic organ prolapse

AIM

To compare total pelvic floor reconstruction with vaginal mesh (TVM) and laparoscopic uterus/sacrocolpopexy (LSC) for the treatment of pelvic organ prolapse (POP).

METHODS

Six hundred and seventy patients with POP stage 3 and 4 underwent LSC (n = 350) or TVM (n = 320) at the West China Second Hospital, Sichuan University between January 2011 and December 2016. Retrospective analysis was done to compare the POP-Q value before operation and 6 months, 5 years after operation, also compare the, patient global impression of change (PGI-C), pelvic floor distress inventory (PFDI-20) and pelvic floor impact questionnaire (PFIQ-7). Patients were followed for a median 36 months. Thirty-five patients in the LSC and 37 in the TVM groups were lost to follow-up.

RESULTS

Preoperative POP value and disease course were similar (P = 0.075). The LSC group was younger (52.8 ± 6.8 vs. 63.9 ± 8.7 years, P = 0.037). Intraoperative bleeding was smaller in the LSC group (74.4 ± 33.2 vs. 150.4 ± 80.3 mL, P < 0.01), with longer operation time (130.0 ± 34.1 min vs 100.4 ± 40.4 min, P < 0.035). The patients were followed for 10-60 months (median, 36 months). Postoperative PISQ-12 (P < 0.01) was better in the LSC group. PFDI-20 and PFIQ-7 were improved after operation in both groups. Objective satisfaction (94.9% vs 91.9%, P > 0.05) and recurrence rate (8.4% vs 5.1%, P = 0.064) were similar. No infection or fistula occurred after operation in both groups. The complication rate of intraoperative bladder injury and postoperative perineal pain in LSC group was lower than those in the TVM group (P < 0.05).

CONCLUSION

LSC showed no serious adverse events and led to higher postoperative satisfaction than TVM in selected patients. Nevertheless, treatment should be selected in accordance with the willingness and condition of each patient.

Laparoscopic pectopexy: a follow-up cyclic biomechanical analysis determining time to functional stability

INTRODUCTION

Pectopexy, a laparoscopic method for prolapse surgery, showed promising results in previous transient testing by this group. It was shown that a single suture, yielding an ultimate load of 35 N, was equivalent to continuous suturing. This was demonstrated in an in vitro cadaver study. This transient data were used to establish an elastic stress-strain envelope. It was now possible to proceed to dynamic in vitro analysis of this surgical method to establish time to functional stability.

METHODS

Cyclic testing of this fixation method was performed on human female embalmed cadaver (cohort 1) and fresh, non-embalmed cadaver (cohort 2) pelvises. The testing envelope was 5-25 N at a speed of 1 mm/s. 100 load regulated cycles were applied.

RESULTS

100 cycles were completed with each model; no overall system failure occurred. Steady state, i.e., functional stability was reached after 14.5 (± 2.9) cycles for the embalmed group and after 19.1 (± 7.2) cycles for the non-embalmed group. This difference was statistically significant p = 0.00025.

CONCLUSION

This trial showed in an in vitro cyclic testing of the pectopexy method that functional stability may be achieved after no more than 19.1 cycles of load exposure. When remaining within the established load envelope of below 25 N, patients do not need to fear global fixation failure. Testing did demonstrate differences in non-embalmed and embalmed cadaver testing. Embalmed cadaver testing tends to underestimate time to steady state by 26.3%.

The Use of the Goldfinger Dissector (GD) in Laparoscopic Sacrocolpopexy

We tested the employment of the GD to create a retroperitoneal tunnel between the promontory and the vaginal apex during the laparoscopic sacrocolpopexy with a mesh. Thus far no report has experimented the use of the GD in this indication. This study's aim was to evaluate the safety and the interest to use this laparoscopic instrument. Sixteen consecutive patients underwent a laparoscopic sacrocolpopexy with the use of the GD and were compared with a control group constituted by the previous 30 cases. The median operating time was 180 min with the use of the GD and represent a gain of time of 22 min in comparaison with our control group. No conversion to open or complications were recorded. In our limited experience, the use of the GD allows a significant gain of time and limits the amount of peritoneal dissection.

Laparoscopic ventral rectopexy with sacrocolpopexy for coexisting pelvic organ prolapse and external rectal prolapse

OBJECTIVES

Pelvic organ prolapse (POP) POP is defined as the protrusion of pelvic organs from the vaginal canal. POP often coexists with internal rectal prolapse or external rectal prolapse (ERP). A series of patients with coexisting POP and ERP who underwent laparoscopic ventral rectopexy (LVR) combined with laparoscopic sacrocolpopexy (LSC) are reported here.

METHODS

Seven patients underwent LVR and LSC together. Fecal incontinence was assessed by the Fecal Incontinence Severity Index (FISI), constipation was assessed by the Constipation Scoring System (CSS), and urinary incontinence was assessed by the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). Anatomical disorders were assessed by Pelvic Organ Prolapse Quantification (POP-Q) and defecography.

RESULTS

The patients' median age was 81 (60-88) years. The median operative time was 380 (282-430) minutes. The median postoperative hospital stay was 3 (1-5) days. There were no postoperative complications. The FISI, CSS, POP-Q, and defecography findings improved postoperatively; however, the ICIQ-SF deteriorated in 2 of 5 patients.

CONCLUSIONS

LVR combined with LSC for coexisting POP and ERP is feasible.

Short-term results of changes in existing and de novo lower urinary tract symptoms after robot-assisted laparoscopic uterosacral ligament suspension and sacrocolpopexy

OBJECTIVE

This study presents short-term outcomes related to changes in existing and de novo lower urinary tract symptoms (LUTS), pelvic pain, and bowel function following robot-assisted laparoscopic uterosacral ligament suspension (RALUSLS) and sacrocolpopexy (RALSC).

METHODS

Observational data for RALUSLS (n = 23) and RALSC (n = 25) collected between August 2014 and March 2016 from a single institute (The University of Texas Medical Branch) were evaluated retrospectively. Patient characteristics, concomitant procedures, and the occurrence of lower urinary tract, pelvic pain, and bowel symptoms were compared between patients undergoing RALUSLS and RALSC.

RESULTS

There was no significant difference in background characteristics between the 2 groups, except for parity, which was high in the RALUSLS group. In the RALUSLS group, patients experienced significant resolution of urinary urgency (P < .001) and frequency, urge and mixed incontinence, and pelvic pain (P < .05). In the RALSC group, there was significant resolution of nocturia, mixed incontinence, pelvic pain, and dyspareunia (P < .05). There was no significant difference in the occurrence of de novo symptoms in the RALUSLS and RALSC groups (P > .05), although newly appearing urinary urgency or frequency and stress or urge incontinence were more common after RALSC.

CONCLUSION

Mixed incontinence and pelvic pain improved significantly in patients after RALUSLS or RALSC. In RALUSLS patients, urgency, frequency, and urge incontinence also improved, whereas additional improvement in nocturia and dyspareunia was evident only in RALSC patients. De novo LUTS developing after these procedures, especially after RALSC, necessitate careful patient consultation prior to surgery.

Laparoscopic inguinal ligament suspension versus laparoscopic sacrocolpopexy in the treatment of pelvic organ prolapse: study protocol for a randomized controlled trial

Background

Pelvic organ prolapse (POP) is a common health problem. The lifetime risk of undergoing surgery for prolapse is 11%. POP significantly affects the effects on quality of life and activities of daily living. Laparoscopic sacrocolpopexy (LSC) has been viewed as the gold standard treatment for women with POP who desire reconstructive surgery. However, LSC is associated with technical difficulties, resulting in a long learning curve and operative time. Recently, our team introduced a new laparoscopic technique of inguinal ligament suspension (LILS) and had confirmed its safety and efficacy in treating vaginal vault prolapse. As a new surgical technique for POP, a prospective randomized controlled trial comparing the LILS with the standard technique of LSC is necessary. Therefore, we will conduct a trial.

Methods

The trial is a randomized controlled trial. It compares LILS with LSC in women with stage 2 or higher uterine prolapse. The primary outcomes of this study are perioperative parameters, including surgical time, blood loss, intraoperative complications, and hospital stay as well as surgical anatomical results using the pelvic organ prolapse questionnaire (POP-Q) classification at 6 weeks, 6 months, 12 months, and annually till 5 years after surgery. Secondary outcomes are subjective improvement in urogenital symptoms and quality of life, postoperative complications, postoperative recovery, sexual functioning, and cost-effectiveness at each follow-up point. Validated questionnaires will be used and the data will be analyzed according to the intention-to-treat principle. Based on an objective success rate of 90%, a noninferiority margin of 15%, and a dropout of 20%, 107 patients are needed in each arm to prove the hypothesis with a 95% confidence interval.

Discussion

The trial is a randomized controlled, multicenter, noninferiority trial that will provide evidence whether the efficacy and safety of LILS is noninferior to LSC in women with symptomatic stage 2 or higher uterine prolapse.

Long-term outcomes of modified laparoscopic sacrocolpopexy for advanced pelvic organ prolapse: a 3-year prospective study

OBJECTIVE

The aim of the study was to evaluate the anatomical and functional outcomes of modified laparoscopic sacrocolpopexy (MLSC) for the treatment of advanced pelvic organ prolapse (POP).

METHODS

From May 2009 to September 2012, a consecutive prospective observational study of 30 participants was conducted to evaluate MLSC as a treatment for symptomatic advanced POP at Peking Union Medical College Hospital. The Pelvic Organ Prolapse Quantification (POP-Q) classification was used to determine the POP stage. Validated tools were used to evaluate symptoms (Pelvic Floor Distress Inventory, PFDI-20) and sexual function (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire, PISQ-12). Measurements were recorded preoperatively and then at 3 months and yearly after surgery. We compared the follow-up results with the preoperative data.

RESULTS

All participants completed a 3-year clinical follow-up routine. The anatomical results at 3 months showed significant improvements (P < 0.05) compared with the preoperative results based on the POP-Q measurements. This improvement remained significant after 3 years (P < 0.05). The anatomical cure rate was 100% and 96.7% at 3 months and 3 years after surgery, respectively. Pelvic floor function remained significantly improved after surgery compared with preceding surgery (P < 0.05) according to the following measures: PFDI-20 (106.2 vs 36.0), Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6, 47.9 vs 13.7), Colorectal-Anal Distress Inventory-8 (CRADI-8, 29.2 vs 9.2), and Urinary Distress Inventory-6 (UDI-6, 29.2 vs 13.2). The participants maintained a high level of sexual function (PISQ-12: 29.0 vs 35.1, P < 0.05). One case of mesh exposure (3.3%) and two cases of de novo dyspareunia (8.7%) were observed.

CONCLUSIONS

MLSC seems to be a safe and effective procedure that achieves good long-term anatomical and functional results.

Laparoscopic prolapse surgery: types and evidence

PURPOSE OF REVIEW

Recommendations for the surgical treatment of pelvic organ prolapse have undergone significant changes over the last few decades.First described to be too difficult, the laparoscopic technique has gained popularity but is still controversial. The recent warning on vaginal mesh was the sign of revival and we start now to have many articles published on results and on techniques for laparoscopic prolapse repair.

RECENT FINDINGS

If nothing is new in the comparison of the routes including vaginal mesh placement, the new articles are very interesting in terms of technical information and recommendations. Those articles are very important and help us understand some failures in the laparoscopic approach mainly in the anterior compartment.

SUMMARY

New models have been created and eventually in the future, we will be able to simulate the repair on our own patients and to assess virtually the mobility of each compartment preoperatively. This will allow us to adjust and tailor the treatment to each patient.
