Surgical treatment of stress urinary incontinence: comparison of robotic-assisted Burch urethropexy with retropubic midurethral sling.

Synthetic retropubic midurethral slings (RMUS) and robotic-assisted Burch urethropexies (RA-Burch) are common surgical treatment options for stress urinary incontinence (SUI). Few data exist comparing the success of these two retropubic surgeries. This retrospective cohort study of RA-Burch and RMUS procedures compared the proportion of patients with subjective cure after RA-Burch compared to RMUS at our institution between 2016 and 2020. Subjective cure was defined as reporting no symptoms of SUI at longest follow-up. Chi-square, Fisher's exact, Mann-Whitney U tests, logistic regression, and Kaplan-Meier log-rank tests were used in analyses. The overall cohort of 235 subjects included 47 RA-Burch cases matched 1:4 with 188 RMUS cases. Patients who underwent RA-Burch were younger (p < .01), had lower BMIs (p = .04), and were more likely to have concomitant procedures, including hysterectomy (p < .01). There was no difference in subjective cure at longest follow-up (p = .76). Median follow-up was longer in the RA-Burch group (p < .01). There was no difference in early postoperative complications, EBL, treatment for persistent SUI, or new urge urinary incontinence at longest follow-up. Both groups experienced postoperative urinary retention at a similar rate, although 4 RMUS patients required sling lysis and one patient experienced a mesh exposure. Patients undergoing RA-Burch had significantly longer OR times when no concomitant procedure was performed (p < .01). There were no significant predictors of SUI recurrence when controlling for baseline variables. This study suggests that RA-Burch and RMUS may be equally efficacious for patients with symptoms of SUI desiring surgical management.

Surgical cost of robotic-assisted sacrocolpopexy: a comparison of two robotic platforms.

IMPORTANCE: Robotic assistance in pelvic organ prolapse surgery can improve surgeon ergonomics and instrument dexterity compared with traditional laparoscopy but at increased costs. OBJECTIVE: To compare total costs for robotic-assisted sacrocolpopexy (RSC) between two robotic platforms at an academic medical center. METHODS: Retrospective cohort of Senhance (Ascensus) RSC between 1/1/2019 and 6/30/21 who were matched 2:1 with DaVinci (Intuitive) RSC. Primary outcome was total costs to hospital system; secondarily we evaluated cost sub-categories. Purchase costs of the robotic systems were not included. T-test, chi-square, and Fisher's exact tests were used. A multivariable linear regression was performed to model total costs adjusting for potential confounders. RESULTS: The matched cohort included 75 subjects. The 25 Senhance and 50 DaVinci cases were similar overall, with mean age 60.5 ± 9.7, BMI 27.9 ± 4.7, and parity 2.5 ± 1.0. Majority were white (97.3%) and postmenopausal (86.5%) with predominantly stage III prolapse (64.9%). Senhance cases had longer OR times (Δ = 32.1 min, p = 0.01). There were no differences in concomitant procedures, intraoperative complications, or short-term postoperative complications between platforms (all p > 0.05). On univariable analysis, costs were similar (Senhance $5368.31 ± 1486.89, DaVinci $5741.76 ± 1197.20, p = 0.29). Cost subcategories (medications, supplies, etc.) were also similar (all p > 0.05). On multivariable linear regression, total cost was $908.33 lower for Senhance (p = 0.01) when adjusting for operative time, estimated blood loss, concomitant mid-urethral sling, and use of the GelPoint mini port system. CONCLUSIONS: Despite longer operating times, total cost of robotic-assisted sacrocolpopexy was significantly lower when using the Senhance compared to the DaVinci system.

Operative Time for Minimally Invasive Sacrocolpopexy: Comparison of Conventional Laparoscopy versus Robotic Platform.

STUDY OBJECTIVE: To evaluate the operative time for minimally invasive sacrocolpopexy using conventional laparoscopy vs robotic assistance. In addition, we sought to compare intraoperative complications, mesh complications, anatomic prolapse recurrence, and retreatment. DESIGN: Retrospective cohort study. SETTING: Academic hospital. PATIENTS: All 142 women who underwent minimally invasive sacrocolpopexy between January 1, 2019, and December 31, 2019. INTERVENTION: We compared operative time between laparoscopic and robotic-assisted sacrocolpopexies. MEASUREMENTS AND MAIN RESULTS: A total of 142 women were included. Mean age was 61.8 ± 9.6 years and mean body mass index 27.1 ± 4.4 kg/m2. A total of 86 (60.6%) sacrocolpopexies were performed laparoscopically and 56 (39.4%) with robotic assistance. There were no significant differences in baseline demographic variables. A higher proportion of concomitant hysterectomies were performed with robotic assistance as compared with laparoscopic cases (n = 42, 73.7% robotic vs n = 43, 50.6% laparoscopic; p <.01). Mean operative times were significantly different between robotic and laparoscopic groups (176.3 ± 45.5 minutes and 195.0 ± 45.4 minutes, p = .02). On linear regression, the variables predicting significant change in operative time were robotic assistance, concomitant hysterectomy, age, body mass index, and no resident involvement. There were no differences in intraoperative bladder or bowel injury, anatomic recurrence beyond the hymen, retreatment, or mesh complications (all p >.05). CONCLUSIONS: Contrary to previous research, the use of robotic assistance does not appear to increase operative time for patients undergoing minimally invasive sacrocolpopexy in a large academic practice.

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.

Surgeon satisfaction and outcomes of tele-proctoring for robotic gynecologic surgery.

Surgical proctoring requires increasing resources in growing healthcare systems. In addition, travel has become less safe in the era of COVID-19. This study demonstrates surgeon satisfaction and safety with tele-proctoring in robotic gynecologic surgery. This pilot study assesses surgeon satisfaction and operative outcomes with a novel operative tele-proctoring system with a continuous two-way video-audio feed that allows the off-site surgeon to see the operating room, surgical field, and hands of the robotic surgeon. After thorough system testing, two experienced surgeons underwent tele-proctoring for hospital credentialing, completing 7 total cases. Each completed pre- and post-surveys developed from the Michigan Standard Simulation Experience Scale. Surgical characteristics were compared between tele-proctored cases and 59 historical cases proctored in-person over the last 8 years. Surgeons reported unanimous high satisfaction with tele-proctoring (5 ± 0). There were no major technologic issues. Five of the tele-proctored cases and 35 of controls were hysterectomies. Mean age was 48.2 ± 1.4 years, mean BMI was 29.6 ± 0.9 kg/m2, and mean uterine weight was 152 ± 112.3 g. Two-thirds had prior abdominal surgery (P > 0.1). Tele-proctored hysterectomies were 58 ± 6.5 min shorter than controls (P = 0.001). There were no differences in EBL or complication rates (P > 0.1). Tele-proctoring resulted in high surgeon satisfaction rates with no difference in EBL or complications. Tele-mentoring is a natural extension of tele-proctoring that could provide advanced surgical expertise far beyond where we can physically reach.

Prolapse Recurrence After Sacrocolpopexy Mesh Removal: A Retrospective Cohort Study.

OBJECTIVES: There is limited literature regarding outcomes after sacrocolpopexy mesh removal. We sought to compare the proportion of prolapse recurrence in women after sacrocolpopexy mesh removal with women who underwent sacrocolpopexy without subsequent mesh removal. We hypothesize that more women will experience prolapse recurrence after mesh removal. METHODS: This is a retrospective cohort study of women who underwent sacrocolpopexy mesh removal between 2010 and 2019. These patients were time matched with women who had a sacrocolpopexy but did not undergo mesh removal. Prolapse recurrence was defined as the leading edge past the hymen or retreatment. Analysis was done using χ, Wilcoxon rank-sum, or t test with a Cox proportional hazard model to assess the association between mesh removal and time to recurrence. RESULTS: We identified 26 mesh removals, which were matched with 78 patients without mesh removal. The most common indications for mesh removal were exposure (69.2%) and pain (57.7%). Women who underwent mesh removal were more likely to have Mersilene mesh (19.2% vs 1.3%, P = 0.006). Recurrence occurred in 46% of women who had mesh removal compared with 7.7% in those without (P < 0.001). When adjusted for age, parity, menopause, smoking, and diabetes status, those who had mesh removal had a 15 times higher hazard of prolapse recurrence (adjusted hazard ratio = 15.4, 95% confidence interval = 4.3-54.8, P = <.0001). CONCLUSIONS: When compared with time-matched controls, women who underwent sacrocolpopexy mesh removal had a significantly higher proportion of prolapse recurrence. Prospective studies are needed to further explore the utility of concomitant prolapse repair at the time of mesh removal.

The impact of fellowship surgical training on operative time and patient morbidity during robotics-assisted sacrocolpopexy.

INTRODUCTION AND HYPOTHESIS: Abdominal sacrocolpopexy is commonly performed for the surgical correction of pelvic organ prolapse (POP) in the USA. Over the last decade, fellowship programs have increased the number of these procedures performed robotically. Currently, there is a paucity of literature exploring the impact of fellowship training on outcomes of robotic-assisted sacrocolpopexy (RASC). We sought to explore the impact of an expert surgeon operating alone versus with a fellow on operative time and perioperative morbidity associated with RASC. METHODS: This is an analysis of a retrospectively collected cohort of all RASCs performed to treat POP from June 2010 to August 2015 by a single attending surgeon. Outcomes were compared by expert surgeon alone and with a fellow. RESULTS: We identified 208 RASCs, of which 124 (59.6%) were performed by an expert surgeon alone and 84 (40.4%) with a fellow. Eight fellows were included, with a median of 7 cases (interquartile range 5-13.5). Cases with fellows were 31.1 min longer than an expert surgeon alone (155.6 vs 124.5 min, p < 0.001), a 25% increase. Increased operative time for fellows remained significant on multivariate regression (34.2 min, p < 0.001) after adjusting for case order postmenopausal status, hysterectomy, mid-urethral sling, and bowel injury. Years in fellowship did not have an impact on operative time (p = 0.80). Complications were seen in 34 women (16.4%). On univariate regression, fellows did not have an impact on complications (OR 1.49, 95% CI [0.65-3.43]), which was unchanged on multivariate regression (OR 0.628, 95% CI [0.26-1.54]). Prolapse recurrence was seen in 19 women (9.5%). Fellows had no impact on prolapse recurrence (OR 0.478, 95% CI [0.17-1.38]), which was unchanged on multivariate regression (OR 0.266, 95% CI [0.17-1.49]). CONCLUSION: When an expert surgeon operated together with a fellow, operative time increased by 34 min without increasing prolapse recurrence or complications.

The Impact of a Dedicated Robotic Team on Robotic-Assisted Sacrocolpopexy Outcomes.

BACKGROUND: Robotic-assisted sacrocolpopexy has been criticized for high cost. A strategy to increase operating room efficiency and decrease cost is implementation of a dedicated robotic team. Our objective was to determine if a dedicated robotic team decreases operative time. STUDY DESIGN: This institutional review board-approved retrospective cohort study included all robotic-assisted sacrocolpopexy performed from June 2010 to August 2015 by a single surgeon at 2 institutions in 1 health system. One hospital had a dedicated robotic team, whereas the other did not. To assess baseline differences, χ and t tests were used. Multivariable linear regression identified factors impacting operative time. RESULTS: Eighty-eight robotic-assisted sacrocolpopexy cases met inclusion criteria. Subjects were primarily white (92.8%) and postmenopausal (85.5%) with stage III prolapse (71.1%). Mean age was 60.6 ± 9.0 years, and BMI was 28.5 ± 5.1 kg/m. Seventeen cases (19.3%) had a dedicated team. In the 71 cases without a dedicated team, there were 16 different surgical technologist and no advanced practice providers. Groups had similar baseline characteristics (all P > 0.05).Mean operative time for the dedicated team was significantly less (131.8 vs 160.2 minutes, P < 0.001), a 17.7% time reduction. The decrease persisted on multivariable regression (ß = -25.98 minutes, P < 0.001) after adjusting for case order on the day (ß = -8.6 minutes, P = 0.002) and prior to hysterectomy (ß = -36.1 minutes, P < 0.001). Operative complications and prolapse recurrence were low overall and not different between the dedicated and nondedicated teams (0% vs 2.9%, P = 0.50; 0% vs 7.5%, P = 0.29). CONCLUSIONS: A dedicated robotic team during robotic-assisted sacrocolpopexy significantly decreased operative time by 26 minutes, a 17.7% reduction at our institution.

The Impact of Individual Surgeon Volume on Hysterectomy Costs.

BACKGROUND AND OBJECTIVE: Hysterectomy is one of the most common surgical procedures women will undergo in their lifetime. Several factors affect surgical outcomes. It has been suggested that high-volume surgeons favorably affect outcomes and hospital cost. The objective is to determine the impact of individual surgeon volume on total hospital costs for hysterectomy. METHODS: This is a retrospective cohort of women undergoing hysterectomy for benign indications from 2011 to 2013 at 10 hospitals within the University of Pittsburgh Medical Center System. Cases that included concomitant procedures were excluded. Costs by surgeon volume were analyzed by tertile group and with linear regression. RESULTS: We studied 5,961 hysterectomies performed by 257 surgeons: 41.5% laparoscopic, 27.9% abdominal, 18.3% vaginal, and 12.3% robotic. Surgeons performed 1-542 cases (median = 4, IQR = 1-24). Surgeons were separated into equal tertiles by case volume: low (1-2 cases; median total cost, $4,349.02; 95% confidence interval [CI] [$3,903.54-$4,845.34]), medium (3-15 cases; median total cost, $2,807.90; 95% CI [$2,693.71-$2,926.93]) and high (>15 cases, median total cost $2,935.12, 95% CI [$2,916.31-$2,981.91]). ANOVA analysis showed a significant decrease (P < .001) in cost from low-to-medium- and low-to-high-volume surgeons. Linear regression showed a significant linear relationship (P < .001), with a $1.15 cost reduction per case with each additional hysterectomy. Thus, if a surgeon performed 100 cases, costs were $115 less per case (100 × $1.15), for a total savings of $11,500.00 (100 × $115). CONCLUSION: Overall, in our models, costs decreased as surgeon volume increased. Low-volume surgeons had significantly higher costs than both medium- and high-volume surgeons.

Evaluating the Impact of Intraoperative Surgical Team Handoffs on Patient Outcomes.

OBJECTIVE: The aim of the study was to assess the impact of intraoperative personnel handoffs on clinical outcomes in patients undergoing minimally invasive sacrocolpopexy (SCP). METHODS: We retrospectively reviewed SCPs performed at an academic center between 2009 and 2014. We analyzed the number of staff handoffs, defined as any instance a scrub technician (tech) or circulating nurse handed off responsibility for a break or shift change. Outcomes included operative (OR) time and composite variables for major complications (conversion to an open procedure, bladder injury, bowel injury, blood transfusion, infection, ileus, bowel obstruction, readmission, or mesh complication) and prolapse recurrence (prolapse at or beyond the hymen or retreatment). Postoperative complications were defined as being within 6 weeks of surgery. Mesh complications and prolapse recurrence were recorded for the entire 68-month study period. RESULTS: Of 814 patients, 97.4% were white, 85.3% postmenopausal, mean (SD) age 59.7 (8.8) years, and mean (SD) body mass index 27.5 (4.5) kg/m. Most had stage 3 prolapse (n = 563, 69.9%). There were 478 (58.7%) laparoscopic and 336 (41.3%) robotic SCPs. The median scrub tech and nurse handoff per case was 1.0 (interquartile range [IQR], 0.0-1.0) and 1.0 (IQR, 1.0-2.0), respectively. Mean (SD) OR time was 204.8 (69.0) minutes. One hundred twenty-nine patients (15.8%) had a major complication and 45 (7.5%) experienced prolapse recurrence over a median follow-up interval of 41.0 weeks (IQR, 12.0-101.0). On multivariable linear regression, each tech and nurse handoff was associated with an increased OR time of 13.6 (P < 0.001) and 9.4 minutes (P < 0.001), respectively. Thus, the median of 1 tech and 1 nurse handoff per case will increase OR time by 23.0 minutes (11.2%). On multivariable logistic regression, staff handoffs were not associated with major complications or prolapse recurrence. CONCLUSIONS: Intraoperative scrub technician and circulating nurse handoffs increased OR time for minimally invasive SCP procedures.

Host response to synthetic mesh in women with mesh complications.

BACKGROUND: Despite good anatomic and functional outcomes, urogynecologic polypropylene meshes that are used to treat pelvic organ prolapse and stress urinary incontinence are associated with significant complications, most commonly mesh exposure and pain. Few studies have been performed that specifically focus on the host response to urogynecologic meshes. The macrophage has long been known to be the key cell type that mediates the foreign body response. Conceptually, macrophages that respond to a foreign body can be dichotomized broadly into M1 proinflammatory and M2 proremodeling subtypes. A prolonged M1 response is thought to result in chronic inflammation and the formation of foreign body giant cells with potential for ongoing tissue damage and destruction. Although a limited M2 predominant response is favorable for tissue integration and ingrowth, excessive M2 activity can lead to accelerated fibrillar matrix deposition and result in fibrosis and encapsulation of the mesh. OBJECTIVE: The purpose of this study was to define and compare the macrophage response in patients who undergo mesh excision surgery for the indication of pain vs a mesh exposure. STUDY DESIGN: Patients who were scheduled to undergo a surgical excision of mesh for pain or exposure at Magee-Womens Hospital were offered enrollment. Twenty-seven mesh-vagina complexes that were removed for the primary complaint of a mesh exposure (n = 15) vs pain in the absence of an exposure (n = 12) were compared with 30 full-thickness vaginal biopsy specimens from women who underwent benign gynecologic surgery without mesh. Macrophage M1 proinflammatory vs M2 proremodeling phenotypes were examined via immunofluorescent labeling for cell surface markers CD86 (M1) vs CD206 (M2) and M1 vs M2 cytokines via enzyme-linked immunosorbent assay. The amount of matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9) proteolytic enzymes were quantified by zymography and substrate degradation assays, as an indication of tissue matrix degradation. Statistics were performed with the use of 1-way analysis of variance with appropriate post hoc tests, t-tests, and Fisher's Exact test. RESULTS: Twenty-seven mesh-vaginal tissue complexes were excised from 27 different women with mesh complications: 15 incontinence mid urethral slings and 12 prolapse meshes. On histologic examination, macrophages surrounded each mesh fiber in both groups, with predominance of the M1 subtype. M1 and M2 cytokines/chemokines, MMP-9 (pro- and active), and MMP-2 (active) were increased significantly in mesh-vagina explants, as compared with vagina without mesh. Mesh explants that were removed for exposure had 88.4% higher pro-MMP-9 (P = .035) than those removed for pain. A positive correlation was observed between the profibrotic cytokine interleukin-10 and the percentage of M2 cells (r = 0.697; P = .037) in the pain group. CONCLUSION: In women with complications, mesh induces a proinflammatory response that persists years after implantation. The increase in MMP-9 in mesh explants that were removed for exposure indicates degradation; the positive association between interleukin-10 and M2 macrophages in mesh explants that are removed for pain is consistent with fibrosis.

Intraovarian oxidized cellulose (Surgicel) mimicking acute ovarian pathology after recent pelvic surgery.

Oxidized regenerated cellulose (Ethicon Surgicel) is often used during surgery to achieve hemostasis. The appearance of Surgicel on postoperative computed tomography (CT) may be mistaken for abscess. Meanwhile, the literature regarding its ultrasound appearance remains scant. We report the CT and sonographic appearances of Surgicel in the right ovary of a 21-year-old woman presenting to the emergency department with pelvic pain 7 days after ovarian cystectomy. The patient was discharged home with only supportive measures, and follow-up ultrasound obtained 26 days later demonstrated resolution of the sonographic abnormality. This case stresses the importance of familiarity with common imaging appearances of topical hemostatic agents and the need to correlate radiologic findings with the patient's clinical condition and prior operative reports to identify patients suitable for conservative management.

Cost analysis when open surgeons perform minimally invasive hysterectomy.

BACKGROUND AND OBJECTIVE: The costs to perform a hysterectomy are widely variable. Our objective was to determine hysterectomy costs by route and whether traditionally open surgeons lower costs when performing laparoscopy versus robotics. METHODS: Hysterectomy costs including subcategories were collected from 2011 to 2013. Costs were skewed, so 2 statistical transformations were performed. Costs were compared by surgeon classification (open, laparoscopic, or robotic) and surgery route. RESULTS: A total of 4,871 hysterectomies were performed: 34.2% open, 50.7% laparoscopic, and 15.1% robotic. Laparoscopic hysterectomy had the lowest total costs (P < .001). By cost subcategory, laparoscopic hysterectomy was lower than robotic hysterectomy in 6 and higher in 1. When performing robotic hysterectomy, open and robotic surgeon costs were similar. With laparoscopic hysterectomy, open surgeons had higher costs than laparoscopic surgeons for 1 of 2 statistical transformations (P = .007). Open surgeons had lower costs performing laparoscopic hysterectomy than robotic hysterectomy with robotic maintenance and depreciation included (P < .001) but similar costs if these variables were excluded. CONCLUSION: Although laparoscopic hysterectomy had lowest costs overall, robotics may be no more costly than laparoscopic hysterectomy when performed by surgeons who predominantly perform open hysterectomy.
