Laparoscopic versus robotic-assisted sacrocolpopexy for pelvic organ prolapse: a systematic review

The Learning Curve in Urogynecology and Functional Urology: A Systematic Review

INTRODUCTION AND HYPOTHESIS

When adopting new methods, surgeons may experience a period of complexity and longer operation times because of their inexperience. This period is known as the "learning curve." This study was aimed at systematically reviewing the current literature on functional urology learning curves.

METHODS

A comprehensive search was conducted across multiple databases from inception to July 2023 with no language restrictions. All original studies on urogynecological and functional urological procedures, including cross-sectional, cohort, and clinical trials, were eligible for inclusion. Relevant data were extracted, and methodological quality was appraised using standardized Joanna Briggs Institute critical appraisal tools. To quantitatively investigate learning curves, a mixed-effects generalized linear regression analysis was conducted on studies employing cumulative summation methods.

RESULTS

From the 7,104 records, 68 studies met the inclusion criteria. The majority of studies were observational and the most common outcome measures were surgical duration, blood loss, and hospital stay. The learning curves varied by procedure type-for incontinence surgeries, 15-80 cases were required; for pelvic organ prolapse surgeries, 18-47 cases; for laparoscopic procedures, 10-105 cases; and for robotic procedures, 5-84 cases. The analysis showed that the number of cases required to surpass the learning curve decreased over time, likely reflecting technological advancements and increased surgical experience.

CONCLUSION

The learning curve for surgical procedures varies significantly. It varies between 5 cases for robotic supratrigonal cystectomy to 75 cases for robot-assisted ventral mesh rectopexy or robotic sacrocolpopexy surgery in 84 cases. These variable learning curves highlight the need for structured training programs and ongoing assessment.

Innovative vaginal manipulator technique vs. traditional method for vaginal fornix deployment in robotic sacrocolpopexy

Introduction and hypothesis

Pelvic organ prolapse (POP) affects approximately 30% of middle-aged and older women, with 11%-19% requiring surgical intervention. Laparoscopic sacrocolpopexy preserves the vaginal axis and length but involves a steep learning curve and longer operation times. Robotic sacrocolpopexy (RSC) addresses these issues, offering enhanced surgical precision. This study aimed to evaluate the feasibility and effectiveness of a novel vaginal manipulator (Hoyte Sacro Tip®; Cooper Surgical, Trumbull, CT, USA) compared with the traditional spatula in RSC.

Methods

This retrospective cohort study included 88 females undergoing RSC at Kawasaki Medical School Hospital between January 2021 and December 2023. Patients were divided into two groups: spatula (n = 50) and vaginal manipulator (n = 38). Data on patient demographics, operative outcomes, and postoperative POP quantification (POP-Q) scores were collected.

Results

Baseline characteristics were similar between the groups, except for gravidity and hypertension, which were higher in the spatula group than that in the vaginal manipulator group. No significant differences were found in operative time, console time, estimated blood loss, or complication rates between the groups (p = 0.08, 0.12, 0.19, and NA, respectively). Hospital stays were shorter in the vaginal manipulator group (median 6.5 vs. 7.0 days, p = 0.03) than in the spatula group. Both groups showed improved POP-Q scores postoperatively. However, the vaginal manipulator group had significantly lower ΔC scores than that of the spatula group (6.26 ± 3.88 vs. 8.53 ± 3.25, p = 0.02).

Conclusions

The vaginal manipulator proved to be a safe and feasible alternative to the traditional spatula, with comparable perioperative outcomes and shorter hospital stays. The manipulator's design facilitated better tissue dissection, potentially improving surgical efficiency.

Postoperative complications and unanticipated healthcare encounters following mini-laparotomy vs. laparoscopic/robotic-assisted sacrocolpopexy: a comparative retrospective study

BACKGROUND

Pelvic organ prolapse is a debilitating condition impacting lives of millions of women worldwide. Sacrocolpopexy (SCP) is considered an effective and durable surgical technique for treatment of apical prolapse. The aim of this study was to compare short-term outcomes including postoperative complications and unanticipated healthcare encounters between patients who underwent SCP with a mini-laparotomy approach compared to patients treated with laparoscopic and robotic-assisted laparoscopic SCP.

METHODS

This was a retrospective cohort study including patients treated for apical prolapse at a university affiliated urogynecology practice. Patients over the age of 18 who underwent abdominal SCP between 2019 and 2023 were included. The cohort was formed into two groups: (1) Patients who underwent SCP through a mini-laparotomy incision (Mini-lap group); (2) Patients who underwent laparoscopic or robotic-assisted laparoscopic SCP (Lap/Robot group).

RESULTS

A total of 116 patients were included in the final analysis. Ninety patients underwent either laparoscopic or robotic-assisted SCP, whereas 26 patients underwent SCP with a mini-laparotomy approach. Study participants exhibited a mean age of 63.1 ± 10.3 years, mean body mass index (BMI) of 25.8 ± 4.9 Kg/m2, and 77.6% of them identified as Caucasian. Upon comparison of demographic and past medical history between groups there were no statistically significant differences in age, BMI, menopausal status, race, parity or comorbid conditions. Patients in the Mini-lap group were less likely to have undergone previous abdominal surgery (11.5% vs. 50.6%, p < 0.001) and had more severe apical prolapse (stage 4 prolapse, 40% vs. 21.2%, p < 0.001) than their counterparts in the Lap/robot group. Regarding intraoperative parameters, length of surgery was significantly shorter in the Mini-lap group compared to the Lap/robot group (97.3 ± 35.0 min vs. 242.0 ± 52.6 min, p < 0.001). When focusing on the primary outcome, postoperative complications within the first 30 days after surgery, there were no differences noted between groups. Additionally, the number of unanticipated healthcare encounters, such as phone calls, clinic visits, emergency department visits, urgent care visits, readmissions and reoperations were similar between groups.

CONCLUSIONS

Mini-laparotomy approach for SCP is safe with comparable intra- and postoperative complications, and unanticipated healthcare encounters compared to conventional minimally invasive methods.

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.

Robot-assisted laparoscopic pelvic floor surgery: Review

Minimally invasive surgical techniques have become more common in pelvic floor reconstructive urogynaecological surgery, specifically, robotic-assisted pelvic floor surgery. Female pelvic floor anatomy is complex, and some repairs require highly experienced surgical skills that can be gained more easily using robotic-assisted surgery. A common application of the robotic platform in urogynaecological surgeries includes sacrocolpopexy, which has become the gold standard approach in the last decade for the correction of apical prolapse. Additional procedures include sacrohysteropexy, sacrocervicopexy, fistula repair, and complex procedures involving the bladder and other pelvic organs. Despite its increasing use and clear benefit in our field, data in the literature and, in particular, randomised controlled trials are sparse. This review provides an update, incorporating recently published literature and our personal experience in that field.

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.

Retrospective analysis of apical prolapse correction by unilateral pectineal suspension: perioperative and short-term results

INTRODUCTION AND HYPOTHESIS

We have previously published the novel method of unilateral pectineal suspension (UPS) for apical prolapse correction. UPS provides mesh-free midline uterus suspension using a single non-absorbable suture to attach the anterior cervix to the lateral part of the iliopectineal ligament. The purpose of this retrospective cohort study was to analyze the short-term efficacy, perioperative complication rate, and overall patient acceptance of the new UPS surgical concept.

METHODS

Forty-seven patients with POP-Q stage 2-4 who underwent robotic UPS between January 1, 2020 and December 31, 2021 were included in the study. Patient data were taken retrospectively from the patient files. Treatment success was the primary endpoint, measured both objectively using a defined composite endpoint and subjectively according to patients' acceptance 3-6 months after surgery during a follow-up examination. Secondary outcome measures included complications and conversions, and effect of additional procedures on operative time.

RESULTS

Treatment success as measured by the defined composite endpoint was 93.6% for the entire cohort. No complications or conversions occurred. Mean operation time for isolated UPS was 46.5 min (n = 33 patients). UPS can be easily combined with additional surgical procedures for repair of remaining pelvic floor defects, incontinence surgery or other indications. Additional procedures performed had a significant influence on operation time (p < 0.0005, n = 14).

CONCLUSIONS

UPS shows highly favorable results when looking at an unselected cohort of patients in need of primary POP surgery with respect to established quality parameters of POP repair.

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.

Robot-assisted pelvic floor reconstructive surgery: an international Delphi study of expert users

BACKGROUND

Robotic surgery has gained popularity for the reconstruction of pelvic floor defects. Nonetheless, there is no evidence that robot-assisted reconstructive surgery is either appropriate or superior to standard laparoscopy for the performance of pelvic floor reconstructive procedures or that it is sustainable. The aim of this project was to address the proper role of robotic pelvic floor reconstructive procedures using expert opinion.

METHODS

We set up an international, multidisciplinary group of 26 experts to participate in a Delphi process on robotics as applied to pelvic floor reconstructive surgery. The group comprised urogynecologists, urologists, and colorectal surgeons with long-term experience in the performance of pelvic floor reconstructive procedures and with the use of the robot, who were identified primarily based on peer-reviewed publications. Two rounds of the Delphi process were conducted. The first included 63 statements pertaining to surgeons' characteristics, general questions, indications, surgical technique, and future-oriented questions. A second round including 20 statements was used to reassess those statements where borderline agreement was obtained during the first round. The final step consisted of a face-to-face meeting with all participants to present and discuss the results of the analysis.

RESULTS

The 26 experts agreed that robotics is a suitable indication for pelvic floor reconstructive surgery because of the significant technical advantages that it confers relative to standard laparoscopy. Experts considered these advantages particularly important for the execution of complex reconstructive procedures, although the benefits can be found also during less challenging cases. The experts considered the robot safe and effective for pelvic floor reconstruction and generally thought that the additional costs are offset by the increased surgical efficacy.

CONCLUSION

Robotics is a suitable choice for pelvic reconstruction, but this Delphi initiative calls for more research to objectively assess the specific settings where robotic surgery would provide the most benefit.

Financial analysis of minimally invasive sacrocolpopexy compared with native tissue vaginal repair with concomitant hysterectomy

INTRODUCTION

Minimally invasive sacrocolpopexy (MISCP) is increasingly used for uterovaginal prolapse, but comparative cost data of MISCP versus native tissue vaginal repair (NTR) are lacking. The objective was to determine the cost difference, from a hospital perspective, between MISCP and NTR performed with hysterectomy for uterovaginal prolapse.

METHODS

This was a retrospective cohort study at a tertiary care center of women who underwent NTR or MISCP with concomitant hysterectomy in 2021. Hospital charges, direct and indirect costs, and operating margin (revenue minus costs) were obtained from Strata Jazz and compared using SPSS.

RESULTS

A total of 82 women were included, 33 MISCP (25 robotic, 8 laparoscopic) versus 49 NTR. Demographic and surgical data were similar, except that MISCP had younger age (50.5 vs 61.1 years, p<0.01). Same-day discharge and estimated blood loss were similar, but operative time was longer for MISCP (204 vs 161 min, p<0.01). MISCP total costs were higher (US$17,422 vs US$13,001, p<0.01). MISCP had higher direct costs (US$12,354 vs US$9,305, p<0.01) and indirect costs (US$5,068 vs US$3,696, p<0.01). Consumable supply costs were higher with MISCP (US$4,429 vs US$2,089, p<0.01), but the cost of operating room time and staff was similar (US$7,926 vs US$7,216, p=0.07). Controlling for same-day discharge, anti-incontinence procedures and smoking, total costs were higher for MISCP (adjusted beta = US$4,262, p<0.01). Mean charges (US$102,060 vs US$97,185, p=0.379), revenue (US$22,214 vs US$22,491, p=0.929), and operating margin (US$8,719 vs US$3,966, p=0.134) were not statistically different.

CONCLUSION

Minimally invasive sacrocolpopexy had higher costs than NTR; however, charges, reimbursement, and operating margins were not statistically significantly different between the groups.

Medium- to long-term outcomes of vaginally assisted laparoscopic sacrocolpopexy in the treatment of stage III-IV pelvic organ prolapse

BACKGROUND

Vaginally assisted laparoscopic sacrocolpopexy (VALS) refers to the placement of synthetic meshes through the vagina in addition to traditional laparoscopic sacrocolpopexy. In this study, we aimed to investigate the medium- to long-term efficacy and safety of VALS for treating stage III-IV pelvic organ prolapse (POP).

METHODS

The study was designed as a case series at a single center. Patients with stage III-IV POP in our hospital from January 2010 to December 2018 were included. Perioperative parameters, objective and subjective outcomes, and complications were assessed.

RESULTS

A total of 106 patients completed the follow-up and were included in our study. Within a median follow-up duration of 35.4 months, the objective cure ratio of VALS reached 92.45% (98/106), and the subjective success rate was 99.06% (105/106). Patients reported significant improvements in subjective symptoms. In eight patients suffering anatomic prolapse recurrence, two posterior POP cases were treated by posterior pelvic reconstruction surgery, while six anterior POP cases did not need surgical therapies. The reoperation rate was 1.89% (2/106). No intraoperative complications occurred. Three patients (2.83%) had postoperative fever, and one (0.94%) had wound infection during hospitalization. Six patients (5.66%) had mesh exposure on the vaginal wall, and de novo urinary incontinence occurred in two patients (1.89%) during the follow-up period.

CONCLUSION

VALS is an effective and safe surgical method for treating severe POP. Therefore, VALS should be considered in the treatment of severe POP due to its favorable subjective and objective outcomes, relatively low rate of infection and acceptable rate of mesh exposure.

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

Background and objective

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

Methods

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

Results

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

Conclusions

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

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.

Sacrocolpopexy experience with a novel robotic surgical platform

INTRODUCTION AND HYPOTHESIS

The objective was to describe early experience performing sacrocolpopexy using a novel robotic surgical platform.

METHODS

This is a case series of all women who underwent robotic-assisted sacrocolpopexy using a new robotics platform (TransEnterix Senhance) between January 2019 and July 2021. All sacrocolpopexies were performed by a single Female Pelvic Medicine and Reconstructive surgeon at a large academic institution. Perioperative information including complications was abstracted from the medical record. Anatomical recurrence was defined as any anatomical point at or past the hymen (≥0). Data are descriptive, with Mann-Whitney U test used for comparison of operative time between the first and second half of the patients.

RESULTS

A total of 25 sacrocolpopexies were performed using the new robotics platform. Mean age was 62.3 years (±9.2) and mean BMI was 26.5 (±3.8). Ten (40.0%) patients had a prior hysterectomy. Most (n = 21, 84.0%) had stage III or IV prolapse preoperatively. Mean operative time was 210.2 min (±48.6) and median estimated blood loss was 35 ml (IQR 25-50). Mean operative time decreased between the first and second half of the patients (231.7 min vs 190.3 min, p = 0.047). There were no major intraoperative complications. Median follow-up time was 16 weeks (IQR 4-34) and there were no subjective recurrences or retreatments during this period. Two patients (8.0%) had anatomical recurrence without subjective bother. There were two postoperative readmissions (8.0%) within 30 days for small bowel obstruction, one treated surgically and the other with nonsurgical management.

CONCLUSIONS

Our case series demonstrates feasibility and successful early adoption of a new robotics platform for robotic sacrocolpopexy.

Abdominal versus robotic sacral colpopexy: A detailed analysis of outcomes

AIMS

Although abdominal sacrocolpopexy (ASC) is considered the gold standard for surgical repair of vaginal vault prolapse, the open surgical approach has significant morbidity. We aim to compare anatomic and functional outcomes in women receiving either robotic-assisted sacral colpopexy (RSC) or ASC for post-hysterectomy prolapse.

METHODS

We present a retrospective chart review of all women who underwent ASC and RSC at our institution and had 12-month follow-up (FU). Pelvic organ prolapse quantification (POP-Q) staging was assessed both preoperatively and postoperatively. Perioperative and demographic details were collected from the medical records.

RESULTS

One hundred twenty four women underwent RSC (mean age 63, median FU 16 months). Those in the ASC group (n = 144) were statistically younger (mean age 60) and had longer FU (median 60 months). Both median day of successful voiding trial and discharge day significantly favored RSC. There were no Clavien Grade IV/V complications for either procedure and three RSC procedures were converted to ASC. Both approaches were associated with a significant improvement in POP-Q stage at FU, with few women requiring additional surgery. Overall, 76% of women in each group were dry from stress urinary incontinence. Improvement in storage and emptying indices, dyspareunia, and quality of life measures was observed after both approaches.

CONCLUSION

RSC demonstrates good support of significant vaginal vault prolapse at medium term FU, with shorter hospital stays and low complication rates. Close FU after RSC over a longer period will be needed to fully assess durability of both functional and anatomic outcomes.

To Robot or Not To Robot: The Use of Robotics in Benign Gynecologic Surgery

The use of robotic-assisted laparoscopic surgery has continued to grow since the Food and Drug Administration approval for robotic-assisted gynecologic surgery in 2005. However, despite this growth in utilization, the data supporting its use in benign gynecologic surgery has not strongly supported its advantages over conventional laparoscopy. Controversy exists between supporters of robotic-assisted laparoscopic surgery and conventional laparoscopy. This article discusses the current literature regarding the use of robotic-assisted surgery in benign gynecologic surgery.

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.

Short and middle-term outcomes of vaginally assisted laparoscopic sacropolpopexy

OBJECTIVE

Vaginally assisted laparoscopic sacrocolpopexy (VALS), which is a combined surgical approach where a vaginal hysterectomy is initially performed, followed by transvaginal placement of synthetic mesh and laparoscopic suspension, can be an alternative to overcome the dissection, suturing limitations of laparoscopic sacrocolpopexy. The aim of this study was to compare the operative times and middle-term anatomic outcomes of women with uterovaginal prolapse undergoing VALS with those of women undergoing abdominal sacrocolpopexy.

METHODS

This is a prospective cohort study that evaluates operation times, anesthesia times, estimated blood loss, middle-term outcomes, perioperative and postoperative complications. We compared the results of 47 women who had the VALS to that of 32 abdominal sacrocolpopexy (AS).

RESULTS

The mean follow up was 22.4 months for AS group and 20.5 months for VALS group. The VALS group (median 1 day) had shorter hospitalization duration than the AS group (median 3 days). The mean operation time was significantly shorter in the VALS group (125.9 minutes) than the AS group (151.9 minutes) (P = .03). There was no significant difference in perioperative and postoperative complication rates. Objective failure rate (8.5% in VALS, 15.6% in AS), subjective failure rates (6.4% in VALS, 9.4% in AS), recurrence (2.1% in VALS, 9.4% in AS) and mesh exposition rates (2.1% in VALS, 9.4% in AS) were similar in both procedures.

CONCLUSIONS

VALS with shorter operative time and hospitalization than conventional AS is a promising modification minimally invasive technique for sacrocolpopexy especially for those inexperienced in laparoscopic sacrocolpopexy.

Sacrocolpopexy compared with transvaginal mesh surgery: a systematic review and meta-analysis

BACKGROUND

The use of mesh is controversial in the treatment of female pelvic organ prolapse.

OBJECTIVES

To systematically review the outcomes of sacrocolpopexy compared with transvaginal mesh surgery and to provide evidence-based suggestions.

SEARCH STRATEGY

The MEDLINE, EMBASE, Cochrane Library and clinicaltrials.gov databases were searched on 21 November 2018.

SELECTION CRITERIA

Randomised controlled trials and prospective and retrospective cohort studies were included.

DATA COLLECTION AND ANALYSIS

Data were extracted by one reviewer and examined by a second reviewer for accuracy. Odds ratios and 95% CI were calculated using random-effects models.

MAIN RESULTS

Twenty comparative studies were included. The meta-analysis was performed with subgroups. The summary odds ratios of the randomised controlled group were 1.84 (95% CI 0.79-4.29, I²  = 75%) for anatomical success, 1.41 (95% CI 0.47-4.24, I²  = 38%) for subjective success, 0.42 (95% CI 0.18-0.98, I²  = 0%) for mesh complications, 0.61 (95% CI 0.20-1.91, I²  = 0%) for prolapse reoperation and 0.44 (95% CI 0.23-0.88, I²  = 0%) for de novo dyspareunia. The mean differences were 0.77 (95% CI 0.31-1.23, I²  = 66%) for total vaginal length and -1.28 (95% CI -2.00 to -0.55, I²  = 66%) for point C after surgery.

CONCLUSIONS

Very-low-quality evidence indicated that the anatomical and subjective success rates of sacrocolpopexy were similar to those of transvaginal mesh surgery; sacrocolpopexy might be more beneficial than transvaginal mesh surgery in terms of mesh-related complication rates, prolapse recurrence and de novo dyspareunia. However, additional high-quality randomised trials with long-term follow-up durations are needed.

TWEETABLE ABSTRACT

Sacrocolpopexy is beneficial after surgical anatomical changes and has decreased rates of mesh-related complications and dyspareunia.

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

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

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

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

Single-port versus multi-port robotic sacrocervicopexy: Establishment of a learning curve and short-term outcomes

OBJECTIVES

The purpose of this study was to compare the learning curves, surgical outcomes and complications of multi-port access robotic-assisted laparoscopic sacrocervicopexy (MP-RSC) to single-port robotic access (SP-RSC) for vaginal apex prolapse.

METHODS

A retrospective study of the first 52 MP-RSC procedures compared with the first 52 SP-RSC procedures performed at one medical center. Primary outcomes were intraoperative bleeding, operative time, and hospitalization. Secondary outcomes were surgical complications.

RESULTS

There was a statistically significant difference in mean operative times between the MP-RSC and SP-RSC procedures: 206.5 ± 39.4 and 187.8 ± 46.2, respectively, P = 0.028. The mean estimated intraoperative blood loss was 35 [20-87.5] ml and 20 [10-47.5] ml, respectively, P = 0.008. Respective mean operative times decreased from the first 15 to the subsequent 15 cases: in the MP-RSC group from 224.2 ± 43.2 to 198.4 ± 36.3 min, P = 0.088, and in the SP-RSC group from 222.4 ± 53.1 to 161.3 ± 28.2 min, P < 0.001. The subsequent 22 cases showed different trends. Hospitalization (days) and level of pain at 24 h postoperative, according to a 1-10 point visual analogue scale, did not differ. Adverse events were rare in both groups.

CONCLUSIONS

MP-RSC and SP-RSC are feasible and the short term outcomes and learning curves for both procedures are comparable.

Laparoscopic sacrocolpopexy is as safe in septuagenarians or elder as in younger women

Background

Data concerning laparoscopic sacrocolpopexy (LSCP) in elder women are scarce. We compared intra-operative and early-postoperative complications associated with laparoscopic colpo-, cervico-, or hysteropexy in women under and above 70 years.

Methods

Retrospective assessment by an independent investigator of a prospective cohort of 571 consecutive women undergoing LSCP in a tertiary unit over an 18-year period. Data included were patient demographics, operative variables, intra-operative, and early (≤ 3 months) postoperative complications. Complications were graded according to the Clavien-Dindo classification and mesh complications categorized using the International Urogynaecological Association (IUGA)-classification.

Findings

Median age was 66 (IQR 15, range 27-91) and 204 (35.7%) patients were older than 70 years. There were no deaths. Strategic conversion rate was 2.3% (13/571), the majority because of extensive adhesions yet early in our experience. Reactive conversion rate was 0.7% (4/571). Among 554 patients who had a completed LSCP, there were 20 intra-operative complications (3.6%), mostly bladder (1.3%) and vaginal (1.1%) injuries. Eighty-four patients had a total of 95 early-postoperative Dindo ≥ II complications (15.1%). Most common complications were infectious and treated medically (Dindo II). Clinically major complications are rare (III = 3.1% and IV = 0.2%). Reoperation for suspected bleeding (IIIb = 0.7%) was the most common reintervention, typically without demonstrable cause. Most mesh complications were vaginal exposures. Septuagenarians were not more likely to have an intra-operative (4.0 vs 3.3% < 70 years, p = 0.686) or early-postoperative complication (13.6 vs 16.0% < 70 years, p = 0.455) than younger patients. Mesh complications were also equally uncommon.

Conclusions

LSCP is as well-tolerated by women above 70 years as by younger women.

Robot-assisted laparoscopic surgery versus conventional laparoscopic surgery in randomized controlled trials: A systematic review and meta-analysis

Importance

This review provides a comprehensive comparison of treatment outcomes between robot-assisted laparoscopic surgery (RLS) and conventional laparoscopic surgery (CLS) based on randomly-controlled trials (RCTs).

Objectives

We employed RCTs to provide a systematic review that will enable the relevant community to weigh the effectiveness and efficacy of surgical robotics in controversial fields on surgical procedures both overall and on each individual surgical procedure.

Evidence review

A search was conducted for RCTs in PubMed, EMBASE, and Cochrane databases from 1981 to 2016. Among a total of 1,517 articles, 27 clinical reports with a mean sample size of 65 patients per report (32.7 patients who underwent RLS and 32.5 who underwent CLS), met the inclusion criteria.

Findings

CLS shows significant advantages in total operative time, net operative time, total complication rate, and operative cost (p < 0.05 in all cases), whereas the estimated blood loss was less in RLS (p < 0.05). As subgroup analyses, conversion rate on colectomy and length of hospital stay on hysterectomy statistically favors RLS (p < 0.05).

Conclusions

Despite higher operative cost, RLS does not result in statistically better treatment outcomes, with the exception of lower estimated blood loss. Operative time and total complication rate are significantly more favorable with CLS.

Current trends and future perspectives in pelvic reconstructive surgery

Our review article illustrates the current trends and future perspectives for the surgical treatment of pelvic organ prolapse.

The future of robotic-assisted laparoscopic gynaecologic surgery in Australia - A time and a place for everything

There has been a significant increase in minimally invasive surgery in gynaecology over the last 15 years, with approximately only one-third of hysterectomies for benign disease now performed via laparotomy. While robotic surgery offers considerable technical advantages over conventional laparoscopy and is associated with only a modest learning curve, the improvement in clinical outcomes is marginal and there are several disadvantages. There are increased set-up and operating times, the need to accommodate and maintain large sophisticated equipment, and the requirement for additional training. The preeminent issue regarding the place of robotic gynaecological surgery is cost. How this is addressed and contained will ultimately determine uptake in Australia. From the published literature to date, robotic surgery compared with conventional laparoscopic surgery is associated with marginal improvements in clinical outcomes for benign hysterectomy and endometrial cancer surgery, but little improvement for other benign gynaecological surgery or for cervical cancer surgery. Robotic surgery probably does improve clinical outcomes in obese and morbidly obese patients and is associated with improved ergonomics for the surgeon. It is likely that there will be continued substantial improvements in robotic surgical platforms into the foreseeable future and that robotic surgery will play an increasingly important role in gynaecological surgery in Australia.

Post-hysterectomy vaginal vault prolapse

Post-hysterectomy vaginal vault prolapse (PHVP) is a recognised although rare complication following both abdominal and vaginal hysterectomy and the risk is increased in women following vaginal surgery for urogenital prolapse. The management of PHVP remains challenging and whilst many women will initially benefit from conservative measures, the majority will ultimately require surgery. The purpose of this paper is to review the prevalence and risk factors associated with PHVP as well to give an overview of the clinical management of this often complicated problem. The role of prophylactic primary prevention procedures at the time of hysterectomy will be discussed as well as initial conservative management. Surgery, however, remains integral in managing these complex patients and the vaginal and abdominal approach to managing PHVP will be reviewed in detail, in addition to both laparoscopic and robotic approaches.

Variability in practice patterns in stress urinary incontinence and pelvic organ prolapse: results of an IUGA survey

INTRODUCTION AND HYPOTHESIS

Members of the International Urogynecological Association (IUGA) come from different geographic locations and practice settings. A member survey regarding practice patterns provides valuable information for practitioners and researchers alike, and allows the IUGA to discover areas to focus on education and information dissemination.

METHODS

A questionnaire was developed by the IUGA Research and Development committee and distributed electronically to IUGA surgeons. Answers were analyzed in reference to demographics, geographic distribution, and academic affiliation.

RESULTS

Five hundred sixty-four members answered the questionnaire, representing a 28 % response rate, and closely reflecting the geographic distribution of IUGA membership. Preferred surgical treatment for uncomplicated SUI was the mid-urethral trans-obturator sling (49.7 %). Vaginal mesh was mainly used for repair of recurrent POP (20.4 %). Pessary use was offered "always" or "frequently" by 61.5 %, with no difference in academic affiliation, but significant differences based on region of practice. Compared to practitioners in non-academic centers, those with academic affiliation utilized Urodynamic studies (UDS) and Magnetic Resonance Imaging (MRI) more frequently in the evaluation of POP. Regions of practice significantly influenced the majority of practice patterns, with the highest impact found in the use of robotic assistance.

CONCLUSIONS

Many practice patterns in the evaluation and treatment of POP and SUI depend on academic affiliation and geographic location. Practice patterns are not always based on most recent evidence-based data.
