Robot-assisted sacrocolpopexy for pelvic organ prolapse: a systematic review and meta-analysis of comparative studies

Short-term outcomes of single port robotic hysterectomy with concomitant sacrocolpopexy

The Da Vinci single port® (SP) robotic platform heralds a new era of minimally invasive surgery (MIS). The primary objective of this study was to assess short-term outcomes in patients undergoing SP robotic hysterectomy with concomitant sacrocolpopexy for pelvic organ prolapse (POP). We performed a retrospective case series at two tertiary care centers between January 2021 and August 2023. Patients with POP electing to undergo SP robotic hysterectomy with concomitant sacrocolpopexy were included. Chart abstraction was used to collect patient demographics and clinical outcomes. Recurrent POP was defined as new bothersome vaginal bulge symptoms and evidence of POP beyond the hymen on postoperative examination. 69 patients were included. Median operative time was 209 min (135-312) and estimated blood loss was 100 mL (20-2000). 1 (1.4%) patient sustained a major vascular injury resulting in laparotomy. Median pain score and morphine equivalents administered in PACU were low at 3 (0-7) and 3.2 (0-27) respectively. At 3 months, 60 (86.9%) patients were seen either in person or via telemedicine for their follow up appointment. 59/60 (98.3%) reported no vaginal bulge symptoms and 50/51 (98.0%) had stage 0 or 1 prolapse on exam. One (1.4%) patient had recurrent prolapse and underwent an additional repair. Postoperative complications included 2 (2.9%) cases of ileus/small bowel obstruction, 1 (1.4%) pelvic hematoma requiring a blood transfusion, and 1 (1.4%) umbilical hernia. The SP robotic platform is a safe and feasible platform for MIS hysterectomy and sacrocolpopexy with good short term anatomic and symptomatic outcomes.

To mesh or not mesh "apical prolapse," that is the question!

Surgical approaches for pelvic organ prolapse have evolved over the last 30 years and is a popular topic for debate, particularly when discussing apical prolapse. Transvaginal native tissue repairs remain the mainstay of POP surgeries, however, transabdominal approaches continue to evolve. Use of interposition material, such as synthetic polypropylene mesh, is the standard when performing an abdominal sacrocolpopexy, however, use of autologous fascia can be considered. This debate article provides an overview of this subject and highlights the value of different approaches to apical prolapse. The authors were asked to support their approach in various scenarios including:extremes of age, prior hysterectomy and intact uterus, desire to avoid mesh, sexual activity, and presence of comorbidities. In discussing common patient scenarios, ultimate decision making on specific POP surgeries is determined by patient preference and goals.

Does a Preoperative Bowel Regimen Change Time to Bowel Movement? A Randomized Clinical Trial

IMPORTANCE

This study is important because it aimed to assess an intervention to decrease patient discomfort after a robotic sacral colpopexy.

OBJECTIVE

Our primary outcome was to determine whether preoperative use of polyethylene glycol decreases time to first bowel movement postoperatively. Secondary outcomes include degree of pain with first bowel movement and stool consistency.

STUDY DESIGN

This was a randomized controlled trial. The experimental group was assigned polyethylene glycol daily for 7 days before surgery and the control group was not. All patients received polyethylene glycol postoperatively.

RESULTS

There was no statistically significant reduction in the time to first postoperative bowel movement when preoperative polyethylene glycol was used (mean [SD] in days for the control and experimental groups of 2.32 [0.99] and 1.96 [1.00], P = 0.21). There was a statistically significant reduction in pain levels with the first postoperative bowel movement in the experimental group (median [IQR] of 4 [2-5] vs 1 [0-2], P = 0.0007). Postoperative day 1 pain levels were also significantly lower in the experimental group (median [IQR] of 4 [3-6] vs 2 [0-4], P = 0.0484). In addition, patients had decreased average postoperative pain levels over 7 days with an estimated difference in the median pain levels of 1.88 units (95% confidence interval, 0.64-3.12; P = 0.0038).

CONCLUSIONS

Preoperative administration of polyethylene glycol did not decrease time to first postoperative bowel movement. Patients in the experimental group exhibited less pain with their first postoperative bowel movement and had improved pain levels on postoperative day 1.

Effect of two different surgical modalities for pelvic organ prolapse on postoperative wound infection in patients: A meta-analysis

Sacrospinous ligament fixation (SSLF) is widely applied to the treatment of female pelvis organ prolapsed. Contradictory findings have already been reported in the comparison of sacrocolpopexy (SC) with SSLF. The objective of this study is to evaluate the efficacy of SC versus SSLF in treating pelvis organ prolapsed after operation. We conducted a meta-analysis of both operative approaches, including PubMed, Embase, and Cochrane Library. In this research, 822 articles were chosen from three databases, 201 were copied, and 10 were included. Among them, 7248 cases were operated on the prolapsed pelvis. It was found that SSLF surgery could significantly decrease the rate of postoperative wound infection after operation (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.42-0.82; p = 0.001). No statistical significance was found among the SSLF and the SC surgery for the post-operation haemorrhage of the patient (OR, 0.81; 95% CI, 0.23-2.83; p = 0.75). No statistical significance was found among the SSLF and the SC surgery for the postoperative period of the patient's operation (mean difference, -15.46; 95% CI, -52.87 to 21.94; p = 0.42). Applying SSLF surgery to treat pelvic prolapse in women may benefit from a reduction in the number of post-operative wound infections. However, SSLF had no statistical significance with respect to the amount of haemorrhage after operation or operation time.

Minimally invasive sacrocolpopexy: efficiency of robotic assistance compared to standard laparoscopy

Minimally invasive abdominal sacrocolpopexy (SC) is the treatment of choice for symptomatic, high-grade, apical or multi-compartmental pelvic organ prolapse (POP), in terms of anatomical correction and treatment durability. Robot-assisted sacrocolpopexy (RASC) could be an attractive alternative to the gold standard laparoscopic sacrocolpopexy (LSC), for its ergonomic advantages in such a technically demanding procedure. However, it has not yet proven its superiority, consequently raising cost-effectiveness issues. Our primary objective was to assess if RASC can achieve better overall operative time (OOT) over LSC, with at least equivalent perioperative results. This was a single-center retrospective study including 100 patients (58 consecutive RASC cases and 42 LSC within the same time-period), with primary endpoint the OOT in both groups. Secondary results included complication rate, hospital stay, short-term anatomic results and OOT within and beyond the RASC learning curve. A multivariate linear regression was carried out for our primary outcome. The groups had comparable characteristics, except for BMI, which was lower in RASC group. The mean OOT was significantly lower in the RASC group (188 vs. 217 min, p ≤ 0.01), even after adjusting for possible confounders. Short-term anatomic results, complication rate, and blood loss were similar in the two groups. Mean hospital stay was significantly longer in the RASC group. Average RASC OOT was significantly shorter after the first 20 cases realized. This study demonstrated a significant reduction of OOT for RASC compared to LSC, with similar perioperative results, encouraging further use of the robotic technology for this indication.

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.

What credentials are required for robotic-assisted surgery in reconstructive and functional urology?

Introduction

The increasing popularity of robotic assisted surgery (RAS) as it is implemented in to sub specialities poses many challenges to ensuring standards in quality and safety. The area of Reconstructive and Functional Urology (RFU) has a wide range and largely complex heterogeneous procedures. In recent years RFU has started to incorporate RAS as the primary method to undertake these procedures due to improved vision, dexterity, and access to deep cavities. To ensure patient safety majority of institutions maintain minimal requirements to operate using RAS however across specialities and institutions these greatly vary.

Methods

A narrative review of all the relevant papers known to the author was conducted.

Results

Specific challenges facing RFU is the inability to rely on case numbers as a surrogate means to measure competency as well the ongoing consideration of how to differentiate between surgeons with robotic training and those with the clinical experience specific to RFU.

Conclusion

This review explores current models of training and credentialling and assess how it can be adapted to suggest a standardised guideline for RFU to ensure the highest standards of patient care.

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 first 60 cases of robotic sacrocolpopexy with the novel HUGO RAS system: feasibility, setting and perioperative outcomes

Introduction

We present the preliminary report of the first 60 cases of robotic sacrocolpopexy (RSCP) performed with a minimally invasive approach by using the new HUGO RAS system (Medtronic) with the aim of assessing its feasibility, safety and efficacy.

Methods

Results in terms of operative time, intraoperative blood loss, post-operative pain, length of hospitalisation, intra and post-operative complications were comparable to previously described laparoscopic and robotic techniques.

Results

Urogynecological assessment at three months follow up showed surgical anatomic success in 96.7% of patients (<2 POP-Q stage), while subjective cure rate was 98.3%.

Conclusions

This is the first series analyzing RSCP outcomes for POP using the new Hugo RAS system. Our results suggest effectiveness both in objective and subjective outcomes, with minimal intra and post-operative complications. Larger series as well as longer follow-up are needed to better define advantages and possible disadvantages of this novel system. Our work may represent the basis of future studies to confirm its safety, efficacy and feasibility, and may provide technical notes for other centres that wish to perform RSCP through this innovative system.

Regional practice variation in pelvic organ prolapse surgery in Tuscany, Italy: a retrospective cohort study on administrative health data

OBJECTIVES

To explore determinants of practice variation in both access, and quality and efficiency of surgical care for pelvic organ prolapse (POP).

DESIGN AND SETTING

A retrospective cohort study employing administrative health data from the Tuscany region, Italy.

PARTICIPANTS

All women over 40 years hospitalised for apical/multicompartmental POP reconstructive surgery (excluding anterior/posterior colporrhaphy without concomitant hysterectomy) from January 2017 to December 2019.

OUTCOMES

We first computed treatment rates just for women residing in Tuscany (n=2819) and calculated the Systematic Component of Variation (SCV) to explore variation in access to care among health districts. Then, using the full cohort (n=2959), we ran multilevel models for the average length of stay and reoperations, readmissions and complications, and computed the intraclass correlation coefficient to assess the individual and hospital determinants of efficiency and quality of care provided by hospitals.

RESULTS

The 5.4-fold variation between the lowest-rate (56/100 000 inhabitants) and the highest-rate (302/100 000) districts and the SCV over 10% confirmed high systematic variation in the access to care. Higher treatment rates were driven by greater provisions of robotic and/or laparoscopic interventions, which showed highly variable usage rates. Both individual and hospital factors influenced quality and efficiency provided by hospitals, but just low proportions of variation were explained by hospital and patient characteristics.

CONCLUSIONS

We found high and systematic variation in the access to POP surgical care in Tuscany and in quality and efficiency provided by hospitals. Such a variation may be mainly explained by user and provider preferences, which should be further explored. Also, supply-side factors may be involved, suggesting that wider and more uniform dissemination of robotic/laparoscopic procedures may reduce variation.

Learning curves and perioperative outcomes of single-incision robotic sacrocolpopexy on two different da Vinci® surgical systems

This study aimed to report a single surgeon's early experience and learning curves of single-incision robotic sacrocolpopexy on two different robotic surgical platforms, namely, the single-site approach on da Vinci Xi^® and single-port approach on da Vinci SP^® surgical systems. This retrospective study included 123 consecutive cases of robotic sacrocolpopexy performed between June 2017 and June 2021 for the patients with Pelvic Organ Prolapse Quantification stage 2-4 symptomatic prolapse. First consecutive 57 cases were performed under the da Vinci Xi^® system applying the single-site manner, whereas the following 66 cases were done under the da Vinci SP^® system. The primary outcome was intraoperative and perioperative complication rates, and the secondary outcome was learning curve of single-incision robotic sacrocolpopexy under the two different robotic surgical platforms. Learning curves based on the operation time were obtained through cumulative sum analysis. The mean age of each group was 65.6 ± 8.7 years for single-site robotic sacrocolpopexy and 63.7 ± 7.6 years for the single-port one (p = 0.202). More than 80% of patients for each group had advanced prolapse stages and underwent concomitant total hysterectomy. The overall baseline characteristics did not differ significantly between groups. The median operation time for each group were 201.0 and 201.5 min, respectively. Both groups showed comparable perioperative outcomes in terms of operation time, intraoperative blood loss, and length of hospital stay. Intraoperative cystostomy rates were 1.8% and 3.0%, respectively, and revealed no statistical difference (p = 0.736). The learning curves were comparable, and the surgeon required less than 15 cases for both single-site and single-port robotic sacrocolpopexies to stabilize operation time. Comparable learning curves and favorable intraoperative and perioperative outcomes of single-incision robotic sacrocolpopexy using two different robotic surgical systems show that both are feasible options for robotic sacrocolpopexy.

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

IMPORTANCE

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

OBJECTIVE

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

STUDY DESIGN

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

RESULTS

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

CONCLUSIONS

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

Robotic sacrocolpopexy with autologous fascia lata: A case series

Objectives

Apical prolapse involves the upper vagina or vaginal vault after hysterectomy. Treatment is indicated for symptomatic women, and surgical approach is considered for women who failed or refused conservative therapy. We performed 10 pickups of autologous fascia, used for robotic sacrocolpopexy (RSCP).

Materials and Methods

We included patients between 60 and 80 years old who showed a Pelvic Organ Prolapse Quantification (POP-q) over the second stage and with symptoms related to prolapse.

Results

All of them underwent autologous fascia lata (AFL) pickup from the right leg and after to RSCP. One patient underwent also posterior colporrhaphy. The mean intraoperative time was 199.2 min (183-230 min). No intra-operatory complications were reported. POP-q assessment during follow-up showed improvements: C point gained on average 7.6 points (5-8) and mean values went from -0.6 to - 8.2 cm (-7 to -9 cm). The three women who had anterior compartment defects shows good anatomical reconstitution with a mean Aa and Ba value of - 2.83 cm (-2.5 to -3 cm) and gained 4 points (average gain: 3.5-4.5 cm). Total vaginal lenght (TVL).

Conclusion

According to these data, in our experience, AFL employment showed a good anatomical result from the first to last follow-up.

Prolapse and mesh reoperations following sacrocolpopexy: comparing supracervical hysterectomy, total hysterectomy, and no hysterectomy

INTRODUCTION AND HYPOTHESIS

Sacrocolpopexy is effective for apical prolapse repair and is often performed with hysterectomy. It is unknown whether supracervical or total hysterectomy at time of sacrocolpopexy influences prolapse recurrence and mesh complications. The primary objective of this study is to compare reoperations for recurrent prolapse after sacrocolpopexy with either supracervical hysterectomy or total hysterectomy, or without concomitant hysterectomy. We also sought to compare these three groups for the incidence of mesh complications and describe cervical interventions following supracervical hysterectomy.

METHODS

A retrospective cohort study of sacrocolpopexy was performed using the MarketScan® Research Database. Women > 18 years who underwent sacrocolpopexy between 2010 to 2014 were identified. Utilizing diagnostic and procedural codes, reoperations for prolapse and mesh complications were identified. Women with < 2 years of follow-up were excluded.

RESULTS

From 2010 to 2014, 3463 women underwent sacrocolpopexy with at least 2 years of follow-up, 910 (26.3%) with supracervical hysterectomy, 1243 (35.9%) with total hysterectomy, and 1310 (37.8%) without hysterectomy. Reoperations for prolapse were similar after supracervical hysterectomy (1.5%), after total hysterectomy (1.1%, p = 0.40), and without hysterectomy (1.5%, p = 0.98). Mesh complications after sacrocolpopexy were similar after supracervical hysterectomy (1.8%), after total hysterectomy (1.5%, p = 0.68), and without hysterectomy (2.8%, p = 0.11). Following supracervical hysterectomy, 0.9% underwent cervical procedures.

CONCLUSIONS

When comparing supracervical and total hysterectomy at time of sacrocolpopexy, there were no significant differences in reoperations for recurrent prolapse, reoperations for mesh complications, or mesh complication diagnoses. This study shows that surgeons can be reassured on performing hysterectomy with sacrocolpopexy.

Long-term Data on Graft-Related Complications After Sacrocolpopexy With Lightweight Compared With Heavier-Weight Mesh

OBJECTIVE

To estimate the long-term incidence and characteristics of graft-related complications, rate of reintervention for graft-related complications and prolapse, and subjective and anatomical outcomes after laparoscopic sacrocolpopexy with heavier-weight (more than 44 g/m2) compared with lightweight (28 g/m2) polypropylene mesh, the latter with resorbable poliglecaprone component.

METHODS

We conducted a single-center study that compared two consecutive prospective cohorts of patients who were undergoing laparoscopic sacrocolpopexy for symptomatic stage 2 or greater cervical or vault prolapse, by using either heavier-weight polypropylene mesh or lightweight polypropylene mesh at a similar duration of follow-up. The primary outcome was the occurrence of graft-related complications and their nature. Secondary outcomes included reinterventions for graft-related complications, recurrent apical prolapse, a subjective outcome (PGIC [Patient Global Impression of Change] score 4 or higher), and an anatomical outcome (point C -1 cm or greater).

RESULTS

We identified consecutive patients: 101 were implanted with heavier-weight polypropylene, and 238 were implanted with lightweight polypropylene; all were audited at comparable follow-up times (heavier-weight mesh: 97 months [interquartile range 16 months]; lightweight mesh: 92.5 months [interquartile range 58 months]). Graft-related complications were more frequent in patients with heavier-weight than lightweight mesh (22.8% [23/101] vs 7.3% [13/178]; hazard ratio [HR] 3.3, 95% CI 1.6-7.1), more frequently symptomatic (heavier-weight mesh: 16.8% [17/101] vs lightweight mesh: 2.8% [5/178]; HR 6.0, 95% CI 2.5-14.3), and more frequently lead to reintervention for graft-related complications (heavier-weight mesh: 18.8% [19/101] vs lightweight mesh: 2.1% [5/238]; HR 4.6, 95% CI 1.9-11.2). The vast majority of patients improved (PGIC score 4 or higher), without difference between groups (heavier-weight mesh: 71/84 [84.9%]; lightweight mesh: 154/178 [86.5%]; HR 0.8, 95% CI 0.6-1.1); neither was there a difference in anatomical failure rate (heavier-weight mesh: 1/60 [1.7%] vs lightweight mesh: 8/131 [6.1%]; HR 0.3, 95% CI 0.1-1.4). Reoperations for recurrent vault prolapse were scarce (0.0% in heavier-weight mesh, vs 0.4% in lightweight mesh).

CONCLUSION

In two consecutive cohorts, the number of graft-related complications, symptomatic graft-related complications, and reinterventions for graft-related complications were higher in patients implanted with heavier-weight polypropylene than when lightweight polypropylene was used. There were no differences in subjective, objective outcomes, and reoperation rates for prolapse.

Single-center study for robotic-assisted laparoscopic sacropexies: a one-fits-all strategy for pelvic organ prolapse?

Purpose

Sarcopenia has been established as the “gold standard” for the treatment of pelvic organ prolapse (POP). Minimal invasive laparoscopy can help to reduce the risks of open access surgery. We compare the surgical results and outcomes of robotic-assisted sacropexies.

Methods

In this monocentric retrospective study we enrolled 49 patients operated on symptomatic POP. Patients were divided into two groups according to the type of robotic-assisted sacropexy: patients with a history of hysterectomy received robotic-assisted sacrocolpopexy (RSCP; n = 19), while patients with subtotal hysterectomy received robotic-assisted cervicosacropexy (RCSP; n = 30). Failure was defined as recurrence of the disease with a need for reoperation. Validated questionnaires (the Pelvic Floor Distress Inventory—20 (PFDI-20) and Pelvic Floor Impact Questionnaire—7 (PFIQ-7)), were used for evaluation of patients quality of life postoperatively.

Results

The comparison between RCSP versus RSCP showed that the latter is related to slightly but not significantly increased recurrence rates and a higher impact of POP symptoms on quality of life in long-term follow-up (p = 0.04). Perioperative data showed similar complication rates in both RSP types but shorter postoperative time of bladder catheterization in the case of RCSP (p = 0.008).

Conclusions

The monocentric long-term data confirm that RSP is a safe and effective method of surgical POP treatment, regardless of the site of the anatomical compartment. In comparison to RSCP, RCSP is associated with a lower impact of POP symptoms on patients’ quality of life with a tendency to slightly lower rates of POP recurrence.

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.

Robot-assisted sacro(hystero)colpopexy with anterior and posterior mesh placement: impact on lower bowel tract function and clinical outcomes at mid-term follow-up

Background:

Robotic sacrocolpopexy (RSCP) is an established option for the treatment of apical, anterior, and proximal posterior compartment pelvic organ prolapses (POP). However, there is lack of evidence investigating how lower bowel tract symptoms (LBTS) may change after RSCP.

Methods:

Data from consecutive patients treated with RSCP for stage 3 or higher POP from 2012 to 2019 at a single tertiary referral center with at least 1 year of follow-up were prospectively collected and retrospectively analyzed. RSCP was performed following a standardized technique which always employed both anterior and posterior hand-shaped meshes. Outcomes were collected at follow-up and analyzed. LBTS were evaluated through the Wexner questionnaire.

Results:

Overall, 114 women underwent RSCP. Eleven were excluded for missing data, whereas 12 had insufficient follow-up. Thus, 91 (79.8%) patients were included in this cohort. Median follow-up was 42 [interquartile range (IQR), 19–62] months. Mean age was 65 ± 10 years. In our series, RSCP was mainly performed for anterior and apical/medium stage 3 POP (in 95.6% of patients). Anatomic success rate of RSCP was 97.8%, with 89 patients with POP stage 0–1 at 12-month follow-up. Two patients (2.2%) experienced POP recurrence and were treated with redo-SCP. No patient experienced clinically significant posterior vaginal wall prolapse after RSCP. When analyzing LBTS, there was no significant change in postoperative total Wexner’s score as compared to the preoperative value ( p > 0.05). However, the manual assistance subscore was statistically significantly lower within the first-year follow-up ( p = 0.04), but it spontaneously improved during the follow-up ( p = 0.12).

Conclusion:

RSCP with simultaneous placement of both anterior and posterior mesh is safe and successful to treat high-stage POP in carefully selected patients. Of note, LBTS appear unaffected by posterior mesh placement, supporting its routine use to prevent posterior POP recurrence. Larger prospective studies are needed to confirm our results.

Robot-assisted Sacrocolpopexy for Recurrent Pelvic Organ Prolapse: Insights for a Challenging Surgical Setting

BACKGROUND

No consensus exists regarding the management of recurrent pelvic organ prolapse (POP). The aim of this study was to evaluate robot-assisted laparoscopic sacrocolpopexy for recurrent pelvic organ prolapse (POP), and to investigate postoperative outcomes.

METHODS

We conducted a single-centre retrospective study including 10 consecutive patients who underwent a robot-assisted sacrocolpopexy for symptomatic POP recurrence from February 2017 to December 2019. Recurrence rates and patient satisfaction, measured by the Pelvic Floor Impact Questionnaire (PFIQ-7) were recorded.

RESULTS

Median age was 57 years (IQR: 54-67). No intraoperative complications were reported. The median hospital stay after surgery was 2 nights (IQR: 1-4). Two patients (20%) experienced early recurrence: at 1 month for one and at 4.5 months for the other. The median follow-up for the remaining eight patients was 18 months (IQR: 12-23). Among the recurrence-free patients, the median PFIQ-7 score was 11.4 at 12 months.

CONCLUSIONS

Robot-assisted sacrocolpopexy is feasible and safe for the management of POP recurrence, with a high patient satisfaction.

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.

Robotic-Assisted Laparoscopic Sacrocolpopexy for Pelvic Organ Prolapse: A Single Center Experience in China

Objective. The aim is to investigate the efficiency and outcome of robotic-assisted sacrocolpopexy (RASC) in a cohort of patients with pelvic organ prolapse (POP) in our Gynecology Department. Methods. We performed a retrospective study of female patients who underwent RASC in Chinese PLA General Hospital from January 2013 to December 2020. Their clinical features included age, degree of prolapse, menopause time, body mass index, pregnancy, delivery, operation time, and bleeding volume. All patients were followed up for more than 6 months. POP-Q was recorded to evaluate the position of prolapsed organs. PFDI-20, PFIQ-7, and PGI-I were used to evaluate the life quality after surgery. Results. Twenty-four patients with POP received RASC in our center. The intraoperative bleeding was 86.9 ± 98.3 ml (20–300 ml). The operation time was 143.5 ± 47.3 min (60–240 minutes). The hospitalization time was 10.4 ± 2.1 days (8–16 days). And the follow-up time was 40.8 ± 22.0 months (6–72 months). In the POP-Q follow-up, postoperative Aa, Ba, Ap, Bp, and C were significantly improved than those before surgery ( $P<0.05$ ). The objective and subjective cure rate was 100%. PGI-I score was very good in 9 (9/24), very good in 10 (10/24), and good in 3 (3/24). Postoperative PFDI-20 and PFIQ-7 were 2.78 ± 3.82 and 1.57 ± 3.86, which decreased dramatically after surgery ( $P<0.05$ ). Mesh exposure occurred in 4 cases (16.7%) at 2–12 months. The exposed diameters were less than 1 cm in 3 cases (2 A/T3/S1) and 1-2 cm in 1 case (3 B/T3/S1). These mesh exposures healed after conservative observation or mesh excision. Conclusion. RASC for POP has the advantage of less bleeding and hospitalization time. It is a minimally invasive option for pelvic organ prolapse.

Laparoscopic lateral suspension for pelvic organ prolapse: A systematic literature review

BACKGROUND

Abdominal lateral suspension with mesh represents an alternative treatment to suspend the vaginal apex.

OBJECTIVES

The aim of this study was to summarize literature data regarding the anatomical and functional outcomes, and intra- and postoperative complications of this technique with minimally invasive approach (laparoscopic/robotic).

SEARCH STRATEGY

Systematic literature search using MEDLINE/PubMed, SCOPUS, Web of Science.

DATA COLLECTION AND ANALYSIS

Two authors extracted data on baseline characteristics (age, BMI, prior pelvic reconstructive surgery, preoperative POP stage), perioperative outcomes (operative time, estimated blood loss, intraoperative and postoperative complications, admission time), objective and subjective success rate, surgical failure, time of follow-up. Data were presented descriptively.

MAIN RESULTS

Thirteen studies were included in the review. The overall number of patients for our analysis was 1066. Patients referred for laparoscopic/robotic lateral suspension were most frequently postmenopausal, aged 50 to 65 years, BMI ≥ 25 kg/m2; 22.2% were already hysterectomized, while 17% had already a previous POP surgery. Operative time ranged from 78.4 ± 29.7 to 254 ± 45 min. The overall anatomic success was more than 90% in the apical compartment and more than 88% in the anterior compartment. Subjective cure rate varies from 78.4% to 100% in medium-term follow-up. Post-operative complication grade >= 3 according to Claiven-Dindo Scale was 1.03%. Mesh erosion rate varied between 0% and 13%.

CONCLUSIONS

Results coming from our systematic review suggest safety, efficacy and feasibility of minimally invasive lateral suspension with optimal anatomical and functional outcomes. Well-designed, randomized, controlled trials are required to confirm this data.

Outsourcing robotic-assisted operations to private hospitals: Cost analysis of a retrospective cohort

BACKGROUND

The Lyell McEwin Hospital entered into a public-private collaborative agreement in 2019 in order to access Da Vinci® Xi Surgical Systems (Intuitive Surgical, Sunnyvale, CA, USA) in private hospitals. This study aimed to examine the costs associated with usage of robot surgical systems under the agreement, and the potential for acquisition in the public hospital.

METHODS

Retrospective data on robotic-assisted and equivalent operations performed between 1 May 2019 and 30 April 2020 were collected and formed subsequent model inputs. Cost data were from hospital records and the local Da Vinci® Xi distributor. Clinical workflow of operations was simulated with a decision-analytic model, with output being costs incurred. The model's base case scenario assumed 5% of cases were robotically assisted.

RESULTS

A total of 35 robotic-assisted, 101 laparoscopic and 34 open operations were performed. Patients were predominantly male and overweight with multiple comorbidities. Length of stay and duration of operation were associated with increased costs (p < 0.001, r² 0.72). In the base case scenario, there was a cost of AU$26 424 per patient, with an open conversion rate of 11%. Increasing robotic-assisted case percentage resulted in reduced cost, open conversion rates and length of stay. Extrapolation of cost model data indicated if 50% were robotic-assisted cases, then the initial capital investment (assumed at AU$4 000 000) could be recovered in 10 years.

CONCLUSION

Our model highlights potential advantages of performing greater numbers of robotic-assisted operations in a collaborative environment. Cost-effective analysis with prospective data could evaluate if these results are translatable and potentially support acquisition of robotic systems in the public sector.

Factors Influencing Selection of Concomitant Total Versus Supracervical Hysterectomy at the Time of Sacrocolpopexy and Associated Perioperative Outcomes

OBJECTIVES

The objective of this study was to describe national practice patterns of hysterectomy type performed with concurrent sacrocolpopexy and determine clinical factors associated with surgical route.

METHODS

We used the National Surgical Quality Improvement Program database with hysterectomy data for this retrospective cohort study. We identified sacrocolpopexy cases from 2014 to 2016 with concurrent hysterectomy and stratified patients into supracervical hysterectomy (SCH) or total hysterectomy (TH). As a secondary analysis, we compared the laparoscopic subset of cases. We performed χ2 and backward stepwise logistic regression analyses to identify factors associated with hysterectomy type and compare complication rates.

RESULTS

A total of 4,615 women underwent SCP with hysterectomy: 55.8% TH and 44.2% SCH. Mean ± SD age was 56.5 ± 11.7 years. Gynecologists represent 96.3% of surgeons; 51.2% were urogynecologists. Urogynecologists were more likely than generalists to perform SCH (58.4% vs 41.6%, P < 0.001). Total hysterectomy was associated with younger age (adjusted odds ratio [aOR], 0.98 per year [0.97-0.99]), greater uterine weight (aOR, 1.05 per 10 g [1.03-1.06]), and non-Caucasian race (aOR, 0.73 [0.58-0.92]). Complication rates were equivalent between hysterectomy type (SCH, 6.2% vs TH, 6.2%; P = 0.956). Laparoscopy was used for 84.4% of surgical procedures. In this subgroup, TH was associated with greater uterine weight (aOR, 1.06 per 10 g [1.04-1.08]) and younger age (aOR, 0.97 per year [0.96-0.98]). Complication rates were similar (SCH, 5.1% vs TH, 5.0%; P = 0.824).

CONCLUSIONS

At the time of sacrocolpopexy, TH is more common than SCH and is associated with younger age and greater uterine weight, although urogynecologists more commonly perform SCH. The overall risk of complications was low and similar between hysterectomy type.

Robot-assisted sacrocolpopexy: not only for vaginal vault suspension? An observational cohort study

INTRODUCTION AND HYPOTHESIS

Surgery for pelvic organ prolapse (POP) has high recurrence rates. Long-term anatomical and patient-reported outcomes after pelvic floor repair are therefore required.

METHODS

This prospective observational cohort study was conducted in a teaching hospital with tertiary referral function for patients with POP. Patients with symptomatic vaginal vault or uterine prolapse (simplified POP Quantification [sPOPQ] stage ≥2), who underwent robot-assisted sacrocolpopexy (RASC) or supracervical hysterectomy with sacrocervicopexy (RSHS), were included. Follow-up visits with sPOPQ evaluations were planned 4 years after surgery. Patients received pre- and postoperative questionnaires reporting symptoms of vaginal bulge, Urogenital Distress Inventory (UDI-6), and Pelvic Floor Impact Questionnaire (PFIQ-7). Primary outcome was patient self-reported symptoms. Secondary outcome was anatomical cure (sPOPQ stage 1) for all vaginal compartments.

RESULTS

Seventy-seven patients were included. Sixty-one patients (79%) were evaluated after 50 months (physical examination n = 51). Symptoms of bulge (95% vs 15% p ˂ 0.0005), median UDI-6 scores (26.7 vs 22.2, p = 0.048), median PFIQ-7 scores (60.0 vs 0, p = 0.008), and median sPOPQ stages in all landmarks improved significantly from the pre- to the postoperative visit. Thirty patients (59%) were completely recurrence free and 96% of patients had no apical recurrence. Most recurrences were asymptomatic cystoceles (20%). There was one surgical re-intervention for recurrent prolapse (1.6%).

CONCLUSIONS

Robot-assisted sacrocolpopexy and RSHS show sustainable results in the treatment of prolapse. Symptoms of bulge, urinary symptoms, and quality of life improved substantially 50 months postoperatively. Patients should be counseled about the risk of anterior wall recurrence and the small chance of recurrent symptoms that need treatment.

Validation of a Simulation Model for Robotic Sacrocolpopexy

OBJECTIVE

We sought to validate a simulation model for robotic sacrocolpopexy (RSCP) that includes multiple steps: presacral dissection/mesh attachment, vaginal mesh attachment, and peritoneal closure.

METHODS

An RSCP training model was developed. Female pelvic medicine and reconstructive surgery (FPMRS) experts and current FPMRS fellows were videotaped using the model; sessions were timed and scored using the Global Evaluative Assessment of Robotic Skills (GEARS) by 3 surgeon reviewers masked to participants' identities. Construct validity was measured by comparing performance on the model between experts and trainees. Interrater reliability was determined by calculating intraclass correlation coefficients for total GEARS scores. Face validity was assessed by a postprocedure questionnaire.

RESULTS

Experts included 9 board-certified FPMRS physicians experienced in RSCP; trainees were 17 fellows. Experts practiced at 7 different institutions in the United States, and the majority (5/7) taught fellows. Trainees were from 7 institutions and in various years of training: postgraduate year (PGY) 5 (n = 6), PGY 6 (n = 5), and PGY 7 (n = 6). Experts' performances were rated significantly higher for total GEARS scores and for relevant domains of the GEARS scale. Intraclass correlation coefficient for the 3 reviewer pairs (0.96-0.99) indicated high interrater reliability. All participants "agreed/strongly agreed" that the model closely approximated live RSCP surgery and was useful for teaching and learning the procedure, indicating high face validity.

CONCLUSIONS

This novel, multistep simulation model demonstrated construct validity and high interrater reliability. Face validity was also established. Consequently, this RSCP model could be used for surgical training and assessment of these discrete surgical skill steps.

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.

Outcomes of robotically assisted laparoscopic lateral suspension (RALLS) with mesh for anterior and apical prolapse

Abdominal sacral colpopexy/hysteropexy is the gold standard for the treatment of vaginal apex support. However, dissection of the promontory may expose to potentially life-threatening complications. To avoid this risk, laparoscopic lateral suspension with mesh is an alternative. Robotic assistance may be helpful in both techniques. The objective of our study was to evaluate outcomes of robotically assisted laparoscopic lateral suspension (RALLS) with mesh for anterior and apical pelvic organ prolapse (POP). From March 2012 to January 2018, 59 consecutive patients underwent RALLS using titanized polypropylene mesh. Between August 2017 and September 2019, all patients were contacted to assess outcome. We performed a clinical exam and asked them to complete the patient global impression of improvement (PGI-I) questionnaire. Fifty-four patients (91.5%) were available for follow-up. Mean age was 58.5 years (28.8-79.8). There were no perioperative complications. The mean follow-up was 33.6 months (11.2-74.1).The objective cure rate (no prolapse beyond hymen) and the subjective cure rate (PGI-I ≤ 2) were 83.3% and 77.2%, respectively. Five women (9.3%) were reoperated for POP recurrence. There was no erosion. Of the 20 women complaining of stress urinary incontinence (SUI) preoperatively, 12 (60%) were cured without any additional SUI procedure. Only two women (10%) required TVT for persistent grade 2 SUI. Two women (5.9%) developed de novo SUI, but none of them required an operation. RALLS repair for POP with mesh is safe and effective and may represent an alternative to sacral colpopexy/hysteropexy.

Is robotic-assisted sacrocolpo(hystero)pexy safe and effective in women over 65 years of age?

INTRODUCTION AND HYPOTHESIS

The objective was to evaluate the safety and efficacy of robotic-assisted sacrocolpo(hystero)pexy in elderly patients with symptomatic apical pelvic organ prolapse and to compare the outcomes of open abdominal and robotic-assisted sacrocolpo(hystero)pexy in geriatric patients.

METHODS

Elderly patients (≥65 years of age) who underwent open abdominal or robotic-assisted sacrocolpo(hystero)pexy for treatment of symptomatic grade 3 and 4 apical pelvic organ prolapse between November 2015 and May 2019 were evaluated retrospectively. The success rates of the procedures, the surgical outcomes, and the perioperative adverse events of both groups were compared. Perioperative adverse events were categorized according to the Clavien-Dindo classification.

RESULTS

Forty-four patients underwent open abdominal sacrocolpo(hystero)pexy and 30 patients underwent robotic-assisted sacrocolpo(hystero)pexy. The mean age in the open abdominal sacrocolpo(hystero)pexy group was 68.4 ± 3.4 years and in the robotic-assisted sacrocolpo(hystero)pexy group it was 69.7 ± 4.1 years. The success rates in the open abdominal sacrocolpo(hystero)pexy and robotic-assisted sacrocolpo(hystero)pexy groups were 59% and 57% at median follow-up time of 28 months and 24 months respectively. Although the mean dosage of the analgesic (10.1 mg/24 h) and the mean length of hospital stay (2.1 days) were significantly lower and shorter for the robotic-assisted sacrocolpopexy group, the mean duration of operation was considerably longer (141.2 min). The rate of grade 2 or higher complications for open abdominal sacrocolpopexy was 16% (7 out of 44) and for robotic-assisted sacrocolpopexy it was 17% (5 out of 30).

CONCLUSIONS

Anatomical outcomes and adverse events are similar in elderly patients undergoing open sacrocolpo(hystero)pexy and robotic-assisted sacrocolpo(hystero)pexy.

Ten years' follow-up after iliococcygeus fixation for the treatment of apical vaginal prolapse

INTRODUCTION AND HYPOTHESIS

Various surgical techniques have been described for vaginal vault prolapse repair, but the best surgical approach is still to be proven. The aim of this study is to report the long-term objective and subjective outcomes of women who underwent iliococcygeus fixation for the treatment of vaginal vault prolapse with a minimum follow-up of 10 years.

METHODS

Women with symptomatic vaginal vault prolapse (Pelvic Organ Prolapse Quantification [POP-Q] stage ≥ 2) who had previously undergone hysterectomy for any reason were prospectively enrolled and treated with iliococcygeus fixation. Subjective success was defined as Patient Global Impression of Improvement (PGI-I) ≤ 2 and an absence of bulging symptoms. Objective success was defined as stage of prolapse < 2 in all compartments. Overall success rate was defined as women without prolapse symptoms, PGI-I ≤ 2, stage of prolapse < 2, and no need for other surgery. Prolpase Quality of Life (P-QOL) questionnaires were completed at the preoperative visit and at every follow-up visit. Multiple logistic regression was performed to identify factors involved in the risk of recurrent POP.

RESULTS

After a median (range) follow-up of 120 (120-132) months, the subjective, objective, and overall cure rates were 82% (32/39), 74.4% (29/39), and 74.4% (29/39), respectively. Only stage IV vault descensus independently predicted POP recurrence after ICG (OR: 7.66 [95% CI: 1.21-9.02]; p < 0.001).

CONCLUSION

Iliococcygeus fixation seems to be a safe and effective option for the treatment of vaginal vault prolapse at 10 years' follow-up.

Perioperative, postoperative and anatomical outcomes of robotic sacrocolpopexy

The study aimed to analyse the anatomical, perioperative and postoperative outcomes of the robotic-assisted sacrocolpopexy (RSCP). After obtaining Institutional Review Board (IRB #19-0167) approval, our retrospective case series included 144 consecutive patients that underwent an RSCP for symptomatic stage II pelvic organ prolapse (POP) or symptomatic/asymptomatic stage III/IV POP. Patient information included operative parameters, perioperative and postoperative complications, readmissions and reoperation. Demographics and baseline characteristics were summarised by frequencies and percentages for categorical variables, and by mean/median, standard deviation, and ranges for continuous variables. In our study, concomitant surgeries with sacrocolpopexy consisted of hysterectomy, Burch colposuspension and midurethral sling. The anatomical success rate was 87.5% and the reoperation rate was 10.4%. The mean follow-up time was 12.5 (±8.7) months. Intraoperative complications 13 (9%) were bowel serosal abrasion, bladder wall injuries, trochar site bleeds, subcutaneous emphysema and a retroperitoneal haematoma. Our results suggest that RSCP is a feasible and safe approach for the treatment of POP with a low complication rate and favourable medium-term outcomes regarding anatomical and symptomatic results.Impact statementWhat is already known on this subject? Pelvic organ prolapse affects more than 25% of women in the United States. Apical and anterior compartment defects are challenging cases and sacrocolpopexy is considered the gold standard treatment option for apical and anterior compartment defects. As technology has advanced, minimally invasive approaches have been popular with their pros.What the results of this study add? We present the highest volume case series in the literature from our tertiary care centre for robotic-assisted sacrocolpopexy (RSCP). Our results suggest that RSCP is a feasible and safe approach for the treatment of POP with a low complication rate and favourable 1-year outcomes regarding anatomical and subjective results.What the implications are of these findings for clinical practice and/or further research? Robotic-assisted sacrocolpopexy has the potential to gain more popularity in the near future based on accumulating data on its feasibility and safety results.

Robotic Sacrocolpopexy for Treatment of Apical Compartment Prolapse

Abdominal sacrocolpopexy is the gold-standard treatment for apical compartment prolapse, as it is more effective and durable than the transvaginal approach. In the current era of minimally invasive surgery, laparoscopic sacrocolpopexy techniques have been described, but have not gained popularity due to their complexity and steep learning curves. To overcome this problem, robotic sacrocolpopexy was introduced, and has shown equivalent outcomes and safety compared to open and laparoscopic sacrocolpopexy based on findings that have been accumulated over 15 years.

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

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

Efficacy and safety outcomes after genital prolapse repair by the vaginal route using the Avaulta Plus® mesh

OBJECTIVE(S)

With aging population, a rise in anterior wall prolapse surgery is expected. The aim of this study is to evaluate the efficacy and safety of genital prolapse repair by the vaginal route using a mixed polypropylene and porcine skin mesh (Avaulta Plus®).

STUDY DESIGN

Retrospective study conducted at Tenon University Hospital, Paris, France. We included seventy-nine women who underwent anterior wall prolapse repair using Avaulta Plus® mesh by the transobturator route for genital prolapse ≥ stage II from September 2008 to December 2017. Pre- and postoperative pelvic organ prolapse classification, functional symptoms, quality of life scores were evaluated, and complications were recorded.

RESULTS

The anatomical success rate for anterior wall prolapse was 97 %. The postoperative complication rate was 29.1 % among which the mesh exposure rate was 7.6 %. Pelvic symptoms such as vaginal discomfort and pelvic heaviness were significantly improved (p < 0.01). Voiding dysfunction were significantly improved (p < 0.01). A significant improvement in the PFDI-20 score (p < 0.01) and PFIQ-7 score (p < 0.01) was observed. After 3 years of follow-up, the recurrence rate was 12 %.

CONCLUSION(S)

Prolapse repair using the Avaulta Plus® mesh is effective and results in a significant improvement in quality of life. The complication rate, including mesh exposure, is acceptable.

Securing Mesh with Delayed Absorbable Suture Does Not Increase Risk of Prolapse Recurrence After Robotic Sacral Colpopexy

Introduction and Objective: Nonabsorbable monofilament suture is traditionally used to secure vaginal mesh for robot-assisted sacral colpopexy (RASC) but can become exposed postoperatively requiring invasive vaginal removal. Polydioxanone delayed absorbable suture may avoid this. We sought to determine the objective and subjective impact of suture choice for mesh fixation. Materials and Methods: A cohort study was undertaken using a prospective registry and subjects were grouped based on type of suture at the time of RASC. Apical failure was defined as C point descent of >2 cm, anterior compartment failure was defined as pelvic organ prolapse quantification (POP-Q) Ba point of >0, and posterior compartment failure was defined as Bp point of >0. Patient-reported outcomes included urogenital distress inventory (UDI)-6 and QoL. Two-tailed t-test and chi-squared were used for analysis. Results: A total of 119 women underwent RASC between 2009 and 2016. Patients had similar preoperative characteristics (Table 1). All POP-Q, UDI-6, and quality of life (QoL) scores improved postoperatively (Tables 1 and 2). Apical failure was noted in 0, anterior failure was noted in 7 (average Ba +1.1 cm in failures), and posterior failure was noted in 4 (mean Bp +1.0 cm) at 16 months' follow-up. Failures in the anterior compartment were much more common in the nonabsorbable monofilament cohort (Table 2). Failures in the apical and posterior compartments were not significantly different between groups. Nine suture erosions were noted in the nonabsorbable monofilament cohort, five requiring excision in the clinic and two in the operating room. Two suture erosions were noted in the delayed absorbable cohort, 0 required excision. Postoperative UDI-6 and QoL scores did not vary significantly between groups (5.3 ± 4.0 vs 5.1 ± 4.0, p = not significant (NS), 2.8 ± 2.0 vs 2.8 ± 2.2, p = NS). [Table: see text] [Table: see text] Conclusion: Securing mesh with delayed absorbable monofilament did not appear to increase risk of failure in patients undergoing RASC and eliminates the need for suture excision postoperatively.

Single-port robotic-assisted laparoscopic sacrocolpopexy with magnetic retraction: first experience using the SP da Vinci platform

The purpose of this study was to describe technical considerations and first outcomes from a single-port robotic-assisted sacrocolpopexy (RSC) using the da Vinci SP platform (Intuitive Surgical, Sunnyvale, CA) and the Levita™ Magnetic Surgical System (San Mateo, CA, USA), a novel magnetic retraction system. Three females with pelvic organ prolapse elected to undergo RSC using the da Vinci SP platform. The supraumbilical incision length was 25 mm through which SP trocar was placed. A 12-mm assistant port was placed in the right upper quadrant. The external magnet was attached to the left side of the bed and used for bowel and bladder retraction. We then proceeded by duplicating the steps of our approach for a RSC performed using a multi-port robotic platform with necessary modifications given the SP approach. Intra-operative outcomes and peri-operative outcomes were collected and reported. The patients were women of 64, 66 and 73 years of age with BMI of 22, 25, and 34, respectively, and POP-Q stage III and IV prolapse. The RSC was performed between 198 and 247 min, estimated blood loss was 10-50 cc, and there were no complications. All patients were discharged home on post-operative day 1. All patients were doing well 1 month out with resolution of bulge symptoms. To our knowledge, this represents the first case series of robotic, magnetic-assisted sacrocolpopexies using the da Vinci SP platform and the Levita™ Magnetic Surgical System. It appears to be a safe and feasible approach, but long-term comparative studies will be necessary to assess functional outcomes.

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.

Learning curve of robot-assisted laparoscopic sacrocolpo(recto)pexy: a cumulative sum analysis

BACKGROUND

Determination of the learning curve of new techniques is essential to improve safety and efficiency. Limited information is available regarding learning curves in robot-assisted laparoscopic pelvic floor surgery.

OBJECTIVE

The purpose of this study was to assess the learning curve in robot-assisted laparoscopic pelvic floor surgery.

STUDY DESIGN

We conducted a prospective cohort study. Consecutive patients who underwent robot-assisted laparoscopic sacrocolpopexy or sacrocolporectopexy were included (n=372). Patients were treated in a teaching hospital with a tertiary referral function for gynecologic/multicompartment prolapse. Procedures were performed by 2 experienced conventional laparoscopic surgeons (surgeons A and B). Baseline demographics were scored per groups of 25 consecutive patients. The primary outcome was the determination of proficiency, which was based on intraoperative complications. Cumulative sum control chart analysis allowed us to detect small shifts in a surgeon's performance. Proficiency was obtained when the first acceptable boundary line of cumulative sum control chart analysis was crossed. Secondary outcomes that were examined were shortening and/or stabilization of surgery time (measured with the use of cumulative sum control chart analysis and the moving average method).

RESULTS

Surgeon A performed 242 surgeries; surgeon B performed 137 surgeries (n=7 surgeries were performed by both surgeons). Intraoperative complications occurred in 1.9% of the procedures. The learning curve never fell below the unacceptable failure limits and stabilized after 23 of 41 cases. Proficiency was obtained after 78 cases for both surgeons. Surgery time decreased after 24-29 cases in robot-assisted sacrocolpopexy (no distinct pattern for robot-assisted sacrocolporectopexy). Limitations were the inclusion of 2 interventions and concomitant procedures, which limited homogeneity. Furthermore, analyses treated all complications in cumulative sum as equal weight, although there are differences in the clinical relevance of complications.

CONCLUSION

After 78 cases, proficiency was obtained. After 24-29 cases, surgery time stabilized for robot-assisted sacrocolpopexy. In this age of rapidly changing surgical techniques, it can be difficult to determine the learning curve of each procedure. Cumulative sum control chart analysis can assist with this determination and prove to be a valuable tool. Training programs could be individualized to improve both surgical performance and patient benefits.

The current state and the future of robotic surgery in female pelvic medicine and reconstructive surgery

In this article, we review the current uses and future directions of robotic surgery in the field of female pelvic medicine and reconstructive surgery. Pelvic surgery is ideal for the use of surgical robots, which provide improved visualization and ease of suturing deep within the pelvis. Robots have been successfully used for the treatment of pelvic organ prolapse, in procedures such as sacrocolpopexy, sacrohysteropexy, and uterosacral ligament plication. Surgeons have used the robotic successfully to treat various etiologies of female pelvic pain including fibroids, endometriosis, and nerve entrapment. Robotic repair of iatrogenic injury has been described with excellent outcomes and avoidance of conversion to open surgery in the event of an injury caused using the robotic platform. While more data is needed on this topic, there has been increasing interest in using the robot for urologic reconstruction including repair of vesico-vaginal fistula, cystectomy, augmentation cystoplasty, and continent and non-continent diversions. Recently the use of the robot has been described in the treatment of stress urinary incontinence in females, with robotic placement of an artificial urinary sphincter. While robotic surgery is associated with increased cost, the outcomes of robotic surgery in female urology are promising. More studies that properly evaluate the benefits of robotic surgery as compared to open and laparoscopic approaches are needed.

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.

Long-term mesh erosion rate following abdominal robotic reconstructive pelvic floor surgery: a prospective study and overview of the literature

Introduction and hypothesis

The use of synthetic mesh in transvaginal pelvic floor surgery has been subject to debate internationally. Although mesh erosion appears to be less associated with an abdominal approach, the long-term outcome has not been studied intensively. This study was set up to determine the long-term mesh erosion rate following abdominal pelvic reconstructive surgery.

Methods

A prospective, observational cohort study was conducted in a tertiary care setting. All consecutive female patients who underwent robot-assisted laparoscopic sacrocolpopexy and sacrocolporectopexy in 2011 and 2012 were included. Primary outcome was mesh erosion. Preoperative and postoperative evaluation (6 weeks, 1 year, 5 years) with a clinical examination and questionnaire regarding pelvic floor symptoms was performed. Mesh-related complications were assessed using a transparent vaginal speculum, proctoscopy, and digital vaginal and rectal examination. Kaplan–Meier estimates were calculated for mesh erosion. A review of the literature on mesh exposure after minimally invasive sacrocolpopexy was performed (≥12 months’ follow-up).

Results

Ninety-six of the 130 patients included (73.8%) were clinically examined. Median follow-up time was 48.1 months (range 36.0–62.1). Three mesh erosions were diagnosed (3.1%; Kaplan–Meier 4.9%, 95% confidence interval 0–11.0): one bladder erosion for which mesh resection and an omental patch interposition were performed, and two asymptomatic vaginal erosions (at 42.7 and 42.3 months) treated with estrogen cream in one. Additionally, 22 patients responded solely by questionnaire and/or telephone; none reported mesh-related complaints. The literature, mostly based on retrospective studies, described a median mesh erosion rate of 1.9% (range 0–13.3%).

Conclusions

The long-term rate of mesh erosion following an abdominally placed synthetic graft is low.

A live porcine model for robotic sacrocolpopexy training

INTRODUCTION AND HYPOTHESIS

Robotic sacrocolpopexy is an effective and durable technique for pelvic organ prolapse repair. However, the learning curve for this procedure has underscored the need for an effective surgical training module. Given the cost, infection risk, poor tissue compliance, and scarcity of human cadavers, the live porcine model represents a realistic, available, and cost-effective alternative. This article describes a live porcine model for teaching robotic sacrocolpopexy to determine whether it teaches key aspects of live human robotic sacrocolpopexy to the learner.

METHODS

This robotic sacrocolpopexy model was created using the Da Vinci Xi or Si robotic system on domestic pigs under general anesthesia. The main steps of the model include: (1) creating the porcine "cervix" and (2) performing robotic sacrocolpopexy. The model was evaluated with a survey given to 18 board-certified surgeons who attended the training course between December 2016 and April 2018.

RESULTS

All of the participants reported improvements in their economy of motion, tissue handling ability, suturing efficiency, and overall performance of robotic sacrocolpopexy. Furthermore, a majority of participants were likely to incorporate aspects of the model into their practice (88.8%) and recommend the model to colleagues (94.2%).

CONCLUSIONS

The porcine model provides a feasible tool for teaching robotic sacrocolpopexy to physicians.

Robot-assisted surgery for the management of apical prolapse: a bi-centre prospective cohort study

OBJECTIVE

Robot-assisted surgery is a recognised treatment for pelvic-organ prolapse. Many of the surgical subgroup outcomes for apical prolapse are reported together, leading to a paucity of homogenous data.

DESIGN

Prospective observational cohort study (NCT01598467, clinicaltrials.gov) assessing outcomes for homogeneous subgroups of robot-assisted apical prolapse surgery.

SETTING

Two European tertiary referral hospitals.

POPULATION

Consecutive patients undergoing robot-assisted sacrocolpopexy (RASC) and supracervical hysterectomy with sacrocervicopexy (RSHS).

METHODS

Anatomical cure (simplified Pelvic Organ Prolapse Quantification, sPOPQ, stage 1), subjective cure (symptoms of bulge), and quality of life (Pelvic Floor Impact Questionnaire, PFIQ-7).

MAIN OUTCOME MEASURES

Primary outcome: anatomical and subjective cure.

SECONDARY OUTCOMES

surgical safety and intraoperative variables.

RESULTS

A total of 305 patients were included (RASC n = 188; RSHS n = 117). Twelve months follow-up was available for 144 (RASC 76.6%) and 109 (RSHS 93.2%) women. Anatomical success of the apical compartment occurred for 91% (RASC) and in 99% (RSHS) of the women. In all compartments, the success percentages were 67 and 65%, respectively. Most recurrences were in the anterior compartment [15.7% RASC (symptomatic 12.1%); 22.9% RSHS (symptomatic 4.8%)]. Symptoms of bulge improved from 97.4 to 17.4% (P < 0.0005). PFIQ-7 scores improved from 76.7 ± 62.3 to 13.5 ± 31.1 (P < 0.0005). The duration of surgery increased significantly for RSHS [183.1 ± 38.2 versus 145.3 ± 29.8 (P < 0.0005)]. Intraoperative complications and conversion rates were low (RASC, 5.3 and 4.3%; RSHS, 0.0 and 0.0%). Four severe postoperative complications occurred after RASC (2.1%) and one occurred after RSHS (1.6%).

CONCLUSIONS

This is the largest reported prospective cohort study on robot-assisted apical prolapse surgery. Both procedures are safe, with durable results.

TWEETABLE ABSTRACT

European bi-centre trial concludes that robot-assisted surgery is a viable approach to managing apical prolapse.
