Outcomes of Robotic Sacrocolpopexy Using Only Absorbable Suture for Mesh Fixation

Evaluating the Long-term Impact of Implementing Standardized Postoperative Opioid Prescribing Recommendations Following Pelvic Organ Prolapse Surgery

IMPORTANCE

Improving opioid stewardship is important, given the common use of opioids and resultant adverse events. Evidence-based prescribing recommendations for surgeons may help reduce opioid prescribing after specific procedures.

OBJECTIVE

The aim of this study was to assess longitudinal prescribing patterns for patients undergoing pelvic organ prolapse surgery in the 2 years before and after implementing evidence-based opioid prescribing recommendations.

STUDY DESIGN

In December 2017, a 3-tiered opioid prescribing recommendation was created based on prospective data on postoperative opioid use after pelvic organ prolapse surgery. For this follow-up study, prescribing patterns, including quantity of opioids prescribed (in oral morphine equivalents [OMEs]) and refill rates, were retrospectively compared for patients undergoing prolapse surgery before (November 2015-November 2017; n = 238) and after (December 2017-December 2019; n = 361) recommendation implementation. Univariate analysis was performed using the Wilcoxon rank sum and χ2 tests. Cochran-Armitage trend tests and interrupted time-series analysis tested for significance in the change in OMEs prescribed before versus after recommendation implementation.

RESULTS

After recommendation implementation, the quantity of postoperative opioids prescribed decreased from median 225 mg OME (interquartile range, 225, 300 mg OME) to 71.3 mg OME (interquartile range, 0, 112.5 mg OME; P < 0.0001). Decreases also occurred within each subgroup of prolapse surgery: native tissue vaginal repair ( P < 0.0001), robotic sacrocolpopexy ( P < 0.0001), open sacrocolpopexy ( P < 0.0001), and colpocleisis ( P < 0.003). The proportion of patients discharged following prolapse surgery without opioids increased (4.2% vs 36.6%; P < 0.0001), and the rate of opioid refills increased (2.1% vs 6.0%; P = 0.02).

CONCLUSIONS

With 2 years of postimplementation follow-up, the use of procedure-specific, tiered opioid prescribing recommendations at our institution was associated with a significant, sustained reduction in opioids prescribed. This study further supports using evidence-based recommendations for opioid prescribing.

Permanent Compared With Absorbable Suture in Apical Prolapse Surgery: A Systematic Review and Meta-analysis

OBJECTIVE

To explore how permanent compared with absorbable suture affects anatomic success in native tissue vaginal suspension (uterosacral ligament suspension and sacrospinous ligament suspension) and sacrocolpopexy with mesh.

DATA SOURCES

MEDLINE, EMBASE, and ClinicalTrials.gov were searched through March 29, 2022.

METHODS OF STUDY SELECTION

Our population included women undergoing apical prolapse surgery (uterosacral ligament suspension and sacrospinous ligament suspension and abdominal sacrocolpopexy). Our intervention was permanent suture for apical prolapse surgery, and our comparator was absorbable suture. We determined a single anatomic success proportion per study. Adverse events collected included suture and mesh exposure, surgery for suture and mesh complication, dyspareunia, and granulation tissue. Abstracts were doubly screened, full-text articles were doubly screened, and accepted articles were doubly extracted. Quality of studies was assessed using GRADE (Grading of Recommendations Assessment, Development and Evaluation) criteria. In single-arm studies using either permanent or absorbable suture, random effects meta-analyses of pooled proportions were used to assess anatomic success. In comparative studies investigating both suture types, random effects meta-analyses of pooled risk ratios were used.

TABULATION, INTEGRATION, AND RESULTS

Of 4,658 abstracts screened, 398 full-text articles were assessed and 63 studies were included (24 vaginal suspension [13 uterosacral ligament suspension and 11 sacrospinous ligament suspension] and 39 sacrocolpopexy). At 2-year follow-up, there was no difference in permanent compared with absorbable suture in uterosacral ligament suspension and sacrospinous ligament suspension (proportional anatomic success rate 88% [95% CI 0.81-0.93] vs 88% [95% CI 0.82-0.92]). Similarly, at 18-month follow-up, there was no difference in permanent compared with absorbable suture in sacrocolpopexy (proportional anatomic success rate 92% [95% CI 0.88-0.95] vs 96% [95% CI 0.92-0.99]). On meta-analysis, there was no difference in relative risk (RR) of success for permanent compared with absorbable suture for uterosacral ligament suspension and sacrospinous ligament suspension (RR 1.11, 95% CI 0.93-1.33) or sacrocolpopexy (RR 1.00, 95% CI0.98-1.03).

CONCLUSION

Success rates were similarly high for absorbable and permanent suture after uterosacral ligament suspension, sacrospinous ligament suspension, and sacrocolpopexy, with medium-term follow-up.

Comparison of outcomes between pessary use and surgery for symptomatic pelvic organ prolapse: A prospective self-controlled study

Purpose

We compared the degree of pelvic floor symptom improvement between pessary use and prolapse surgery.

Materials and Methods

Pessary-naïve women who elected prolapse surgery were enrolled and used a pessary preoperatively (for ≥7 days and ≤30 days). Pelvic floor symptoms were assessed at baseline, after pessary use, and at 3 months postoperatively. The primary outcome was concordance in the degree of symptoms improvement between pessary use and surgery, as assessed by Patient Global Impression of Improvement (PGI-I). Secondary outcomes were related to prolapse specific symptoms on validated questionnaires (POPDI-6, PFIQ-7). The McNemar test was used for comparisons of discordant pairs for comparisons of the PGI-I ratings after pessary use and surgery.

Results

Sixty-one participants were enrolled (March 2016 through April 2019) and 58 patients used a pessary. Mean±standard deviation age was 60.7±10.7 years; 24.1% had prior hysterectomy, and 13.8% had prior prolapse surgery. While both treatments demonstrated symptomatic improvement, concordance in the degree of overall improvement on the PGI-I score was poor (n=40); responses significantly favored more improvement postoperatively (p<0.001). Pessary use and surgery were associated with significant improvements in prolapse symptoms from baseline on POPDI-6 (both p<0.001) and POPIQ-7 (pessary, p=0.002; surgery, p<0.001). The degree of improvement was larger postoperatively compared to post-pessary use on POPDI-6 (p<0.001) and PFIQ-7 (p=0.004).

Conclusions

Both pessary use and surgery significantly improved pelvic floor symptoms from baseline. However, concordance in degrees of improvement between these treatments was poor, with more favorable outcomes after surgery for prolapse symptoms.

Advanced Cystocele is a Risk Factor for Surgical Failure Following Robotic-Assisted Laparoscopic Sacrocolpopexy

STUDY OBJECTIVE

To assess the outcome of robotic-assisted laparoscopic sacrocolpopexy (RALSCP) and to identify risk factors for surgical failure and long term complications in patients at high risk for surgical failure.

DESIGN

Retrospective cohort study.

SETTING

A university hospital.

PATIENTS

Sixty-seven women with pelvic organ prolapse at high risk for surgical failure.

INTERVENTIONS

RALSCP from November 2012 to July 2020.

MEASUREMENTS AND MAIN RESULTS

Information was collected from the electronic medical records. Pre-operative and post-operative assessment included a urogynecologic history, prolapse staging, cough stress test, and validated quality of life questionnaires. Anatomical success was defined as POP stage less than 2 at last follow-up. Mean follow-up was 24.6 ± 17.9 months. Sixteen women (23.9%) reported bulge symptoms at the latest follow-up; upon POP-Q staging, surgical failure or recurrence was observed in 35 (52.2%) patients. On multiple logistic regression analysis, a pre-operative POP-Q point Ba measurement ≥ 3 cm beyond the hymen was independently related to surgical failure. Late post-operative complications included three (4.5%) cases of post-operative ventral hernia and five (7.5%) cases of mesh erosion, all in patients operated using Ethibond sutures.

CONCLUSIONS

Anatomical success of RALSCP in POP patients at high risk for surgical failure is worse than previously reported. Advanced pre-operative anterior vaginal wall prolapse is a risk factor for surgical failure. Delayed absorbable sutures for vaginal mesh fixation seem to be safer than multifilament, permanent sutures, in terms of the risk for mesh erosion.

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.

The Austrian Sacrocolpopexy Registry: Surgical Techniques, Perioperative Safety, and Complications

STUDY OBJECTIVE

Sacrocolpopexy (SCP) has become the standard procedure to correct uterovaginal prolapse in women, but techniques and approaches are not standardized. We report the results of the Austrian Sacrocolpopexy Registry, which aimed to collect data on surgical techniques and perioperative outcomes.

DESIGN

The Austrian Urogynecology Working Group initiated a registry to assess surgical variability and perioperative safety of SCP. The study was performed at 14 centers (13 in Austria,1 in Switzerland). Institutional review board approvals were obtained.

PATIENTS

Consecutive patients with symptomatic pelvic organ prolapse (POP).

INTERVENTIONS

SCP in the course of routine POP treatment.

MEASUREMENTS AND MAIN RESULTS

Preoperative assessment included demographic data, clinical data on bladder, and bowel functions and POP-Q status. Surgical data included surgical approach (open, laparoscopic, robotic), type of mesh, depth of dissection, nerve sparing techniques, suture materials, uterus or cervix-sparing techniques, peritoneal closure, and concomitant surgeries. A total of 401 patients were recruited into the study. The mean age was 57 years (range: 26-84) and mean body mass index was 34. A total of 137 (34%) patients had undergone previous surgery for prolapse and in 264 cases SCP was the primary procedure. A total of 170 (42%) patients had undergone previous hysterectomy; For patients with uterus, SCP was performed with subtotal (n = 148) or total (n = 3) hysterectomy. A total of 285 (71%) SCPs were done laparoscopically, 102 (25%) robotically and 10 (3%) per laparotomy. The conversion rate from laparoscopy to abdominal surgery was 4.5%. Various meshes and suture materials were used and fixation techniques also varied widely. Four patients underwent reoperation within 30 days (2 trocar herniations, and 1 bowel obstruction, 1 compartment syndrome). One patient died of aortic dissection 7 days after SCP.

CONCLUSIONS

Most SCPs in this registry were performed laparoscopically, but there was considerable variation in surgical techniques. Perioperative morbidity appears modest.

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.

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.

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.

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.

[Old wine in new bottles-proven open-surgical procedures for the treatment of pelvic organ prolapse]

Urinary incontinence and pelvic organ prolapse (POP) are increasing due to demographic factors. Increasing life expectancy and sociocultural demands of women require successful treatments that also have low complication rates. Classic open procedures such as colposuspension or colposacropexy (native tissue repair as well as mesh procedures) are experiencing a renaissance due to the current critical view of mesh-repair pelvic floor surgery and continue to be of great importance. With suitable patient selection, long-term results of abdominal procedures are on a par with minimally invasive techniques. Cosmetically acceptable results can be achieved with optimized incisions. The therapeutically relevant target for apical fixation is the elevation angle of the vagina (EAV). Minimally invasive mesh-based primary reconstructions and interventions for POP recurrence proved to be superior to conventional procedures due to good long-term results, lower recurrence rates and reduced early and late complication rates when anatomically correct and gentle surgery is performed with a critical selection of textile implants. Abdominal procedures are not inferior to minimally invasive techniques when instrumental suturing techniques and modern instruments are used. Adequate and critical information about surgical options and possible risks of complications should be provided in a timely manner. Education and training in modern diagnostics as well as in abdominal and current minimally invasive techniques and complication management should be implemented according to the guidelines and recommendations of professional societies, the Food and Drug Administration and the European Network of Information Centres.

Long-term outcomes of robotic mesh sacrocolpopexy

The aim of the study is to evaluate anatomic and functional late-term outcomes of robotic mesh sacrocolpopexy (RMS) at a single tertiary-care institution. Following IRB approval, a retrospective chart review of a prospectively collected database on consecutive patients who underwent RMS for symptomatic pelvic organ prolapse and had 3 year minimum follow-up was performed. Data collected included physical examination, validated questionnaires including Urogenital Distress Inventory, Incontinence Impact Questionnaire, and global Quality of Life (QOL). The primary outcome was failure defined as the need for re-operation and/or prolapse recurrence by examination. Those with office follow-up < 36 months underwent structured phone interviews. Between 12/2007 and 2/2012, 56 women underwent RMS. Thirty women had follow-up ≥ 3 years (median 64 (IQR 48-85) months). Mean C-point went from - 2.33 (range 0 to - 5) to - 9.00 (0 to - 12) (p < 0.01), and mean QOL score from 3.93 (0-10) to 1.93 (0-8) (p < 0.01). Two developed recurrent vault prolapse later on at 26 and 34 months, respectively. Four women (13%) required surgery for secondary prolapses, with three for anterior compartment and one for posterior compartment. Sixteen of twenty six were contacted via structured phone interviews, with 14 doing well, one deceased, and one who underwent a secondary posterior compartment prolapse 6 years later at an outside facility. This long-term study indicates durability for RMS in the management of symptomatic pelvic organ prolapse.
