Surgical management of apical pelvic support defects: the impact of robotic technology

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.

Robotic single-site surgery in benign gynecologic diseases: Experiences and learning curve based on 626 robotic cases at a single institute

AIM

The purpose of this study was to report on 626 cases of successful robotic single-site (RSS) surgeries to address various types of gynecologic disease and to evaluate the outcomes and learning curve inherent to RSS surgery in the gynecology field.

METHODS

A total of 626 cases of RSS surgeries were performed by 3 gynecologic surgeons at Ewha Womans University Medical Center, Robot Surgery Center from November 2014 to January 2018 were collected retrospectively. All of the patients' charts were reviewed, and the clinical characteristics and surgical variables were analyzed.

RESULTS

Among the total of 626 cases, there were 220 cases of RSS myomectomy (RSSM), 182 cases of RSS hysterectomy (RSSH), 195 of RSS adnexectomy, 24 of RSS sacrocolpopexy (RSS SCP) and 5 were classified as other RSS surgeries. The patient's mean age was 38.98 ± 10.07 years. There was 3.99 ± 2.15 min of mean docking time and 117.78 ± 51.18 min of mean operating time. The surgical variables were analyzed annually. The total operating time was seen to decrease significantly according to each period. The docking time declined significantly and gradually after 1 year. We also analyzed each of the surgical types by time. The operating time of RSSH, RSSM, RSS adnexectomy and RSS SCP fell over time. The tendency found was for operating time to decline sharply following the first 10 cases. When we analyzed the data at annual intervals, the operating time was most significantly less and stable following the first year. There were a few intraoperative or perioperative complications in 16 cases (2.6%).

CONCLUSION

Robotic single-site surgery is a feasible and safe procedure for treating various kinds of gynecologic diseases. The learning curve was approximately 10 cases of RSS surgery in gynecologic disease, having a greater amount of experience at performing RSS surgery was revealed to be key to achieving better surgical outcomes.

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.

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.

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.

Sexual function after robot-assisted prolapse surgery: a prospective study

Introduction and hypothesis

Female pelvic organ prolapse (POP) can severely influence sexual function. Robot-assisted surgery is increasingly used to treat POP, but studies describing its effect on sexual function are limited. The objective of this study was to evaluate sexual function after robot-assisted POP surgery.

Methods

This prospective cohort study included all patients who underwent a robot-assisted sacrocolpopexy (RASC) or supracervical hysterectomy with sacrocervicopexy (RSHS). Exclusion criteria were unknown preoperative sexual activity status or concomitant surgery. In sexually active women, sexual function was measured with the translated validated version of the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Changes in sexual activity were scored. Prolapse stages were described using the simplified Pelvic Organ Prolapse Quantification (S-POP) system.

Results

A total of 107 women were included (median follow-up 15.3 months). No difference was found in the total number of sexually active women before and after surgery [63 (58.9%) vs. 61 (63.5%), p = 0.999]. Significantly fewer women avoided sexual intercourse postoperatively compared with preoperatively. Preoperatively, sexual intercourse was avoided due to vaginal bulging (2% vs. 24%, respectively, p = 0.021). Total mean PISQ-12 scores improved significantly 1 year after prolapse correction (33.5 vs. 37.1; p = 0.004), mainly due to improved scores on the physical and behavioral–emotive domain. No significant difference in pre- and postoperative complains of dyspareunia was found.

Conclusion

Robot-assisted middle-compartment surgery improved sexual function 1 year after surgery according to enhanced physical and emotional scores. The total number of sexually active women and complains of dyspareunia before and after surgery did not differ.

New Developments in Robotics and Single-site Gynecologic Surgery

Within the last 10 years there have been significant advances in minimal-access surgery. Although no emerging technology has demonstrated improved outcomes or fewer complications than standard laparoscopy, the introduction of the robotic surgical platform has significantly lowered abdominal hysterectomy rates. While operative time and cost were higher in robotic-assisted procedures when the technology was first introduced, newer studies demonstrate equivalent or improved robotic surgical efficiency with increased experience. Single-port hysterectomy has not improved postoperative pain or subjective cosmetic results. Emerging platforms with flexible, articulating instruments may increase the uptake of single-port procedures including natural orifice transluminal endoscopic cases.

A systematic review and meta-analysis of conventional laparoscopic sacrocolpopexy versus robot-assisted laparoscopic sacrocolpopexy

BACKGROUND

Robot-assisted laparoscopic sacrocolpopexy (RALSC) has spread rapidly without the availability of comprehensive and systematically recorded outcome data.

OBJECTIVE

To systematically review and compare the outcomes of laparoscopic sacrocolpopexy (LSC) and RALSC.

SEARCH STRATEGY

PubMed and Scopus were searched for reports published from 2000 to 2014, using the search terms "robotic sacrocolpopexy," "laparoscopic sacrocolpopexy," and "sacral colpopexy."

SELECTION CRITERIA

Studies were included if they directly compared the outcomes of RALSC and LSC, the sample size in each group was more than 15, the follow-up duration was longer than 3 months, and the report was in English.

DATA COLLECTION AND ANALYSIS

The studies' characteristics, quality, and outcomes were recorded. Random-/fixed-effects models were used to combine data.

MAIN RESULTS

Data on 264 RALSC and 267 LSC procedures were collected from seven studies. The mean operative time was longer in the RALSC group (245.9 minutes vs 205.9 minutes; P<0.001). The estimated blood loss in the two groups was similar (114.4 mL vs 160.1 mL; P=0.36). The differences in incidence of intraoperative/postoperative complications were also similar (P=0.85 vs P=0.92). The costs of RALSC were significantly higher than were those of LSC series in each of three studies (P<0.01 for all).

CONCLUSIONS

The clinical outcomes of prolapse surgery are similar with RALSC and LSC, but RALSC is less efficient in terms of cost and time.

A comparison of shoulder pressure among different patient stabilization techniques

OBJECTIVE

The purpose of this study was to evaluate the pressure placed on the shoulders as a function of varying degrees of head-down tilt (the Trendelenburg position) and to compare these pressures among 3 different patient-positioning systems.

STUDY DESIGN

Participants were placed in the dorsal-lithotomy position with arms tucked and tilted at 5, 10, 15, 20, 25, and 30 degrees of head-down tilt. Using a manometer, we measured the pressure (centimeters of water) on the shoulders at each angle for 3 support devices: the Skytron shoulder support (Skytron, Grand Rapids, MI), the Allen shoulder support (Allen Medical Systems, Acton, MA), and the Allen Hug-u-Vac.

RESULTS

Among 23 participants, body mass index (mean ± SD) was 24.5 ± 4.3 kg/m(2). As the tilt angle increased, so did the shoulder pressure for all support systems. At a 30-degree Trendelenburg position, the Allen Hug-u-Vac transmitted less pressure to the shoulders than the Skytron (right and left, P < .001) and the Allen shoulder supports system (right, P < .001; left, P = .434). Each participant was asked, "Which system was most comfortable?" Seventy-four percent of the participants reported that they preferred the Hug-u-Vac (P < .001).

CONCLUSION

Shoulder pressure increases as tilt angle increases. Of the 3 support systems that were tested, the Allen Hug-u-Vac transmitted less pressure to the shoulders at a 30-degree Trendelenburg position than the Skytron and the Allen shoulder support systems.
