Robotic versus vaginal urogynecologic surgery: a retrospective cohort study of perioperative complications in elderly women.

Objectives The primary objective was to compare perioperative complications after robotic surgery (RS) versus vaginal surgery (VS) for apical prolapse repair in elderly women. The secondary objectives were to (1) assess whether tools designed to predict surgical morbidity, the American Society of Anesthesiologists (ASA) class and the Charlson Comorbidity Index (CCI), are useful in the elderly urogynecologic population and (2) to classify complications during urogynecologic apical procedures using the Dindo classification system. Methods We reviewed medical records of women 65 years or older who underwent RS or VS between March 2006 and April 2011. Procedures included robotic sacrocolpopexy and sacrocervicopexy, vaginal uterosacral ligament suspension, sacrospinous ligament suspension, colpocleisis, and Uphold vaginal mesh placement. We assessed preoperative risks using ASA and CCI classification and complications using Dindo grade. Results There were 136 eligible cases (RS, 70; and VS, 66) during the 5-year study period. Women who underwent RS were younger (70 vs 74 years; P < 0.001). Vaginal surgery had more severe comorbidities as measured by the CCI (P = 0.012) but similar ASA profiles (P = 0.10). Robotic surgery had longer operative times (P < 0.001) but a lower estimated blood loss (P < 0.001). There were fewer postoperative complications in RS (P = 0.005). However, complication severity based on Dindo grade was similar between RS and VS, with most surgeries having no complications. Conclusions In the elderly women, RS was associated with fewer postoperative complications than VS. Overall, all procedures were associated with few complications, and either route may be reasonable in the elderly population.

Diagnostic accuracy of retrograde and spontaneous voiding trials for postoperative voiding dysfunction: a randomized controlled trial.

OBJECTIVE: To compare the diagnostic accuracy of two voiding trial methods to predict postoperative voiding dysfunction. METHODS: Women undergoing operations for urinary incontinence, prolapse, or both urinary incontinence and prolapse from November 2009 and March 2010 were randomized into one of two groups: retrograde or spontaneous. All patients underwent both techniques of voiding trials with randomization determining order. RESULTS: Fifty women were randomized to 25 per group. Failure rates were 62% for retrograde and 84% for spontaneous. Women who failed both had 12.6±14.4 days of retention compared with 2.5±2.1 days for those who failed only one method (P=.004). The retrograde method had 94.4% sensitivity and 58.1% specificity to detect postoperative voiding dysfunction lasting at least 7 days compared with the spontaneous method with 100% sensitivity and 25.8% specificity. Positive and negative predictive values for the retrograde method were 56.7% and 94.7%, respectively, compared with the spontaneous method with 43.9% and 100%. Retrograde was preferred by patients (51.1% compared with 44.4%) regardless of randomization. CONCLUSION: The retrograde method is more accurate in evaluating postoperative voiding dysfunction, although both tests had a low positive predictive value. A longer period of retention was seen with failure of both methods. Retrograde was preferred by patients and provides an efficient alternative to the spontaneous method of voiding trial.

Effect of anticholinergic use for the treatment of overactive bladder on cognitive function in postmenopausal women.

BACKGROUND Overactive bladder (OAB) is a common condition affecting the elderly. The mainstay of treatment for OAB is medical therapy with anticholinergics. However, adverse events have been reported with this class of drugs, including cognitive changes. OBJECTIVE The objective of this study was to investigate the effect of an anticholinergic medication, trospium chloride, on cognitive function in postmenopausal women being treated for OAB. METHODS This was a prospective cohort study conducted at a urogynaecology clinic at one academic medical centre from January to December 2010, with 12-week follow-up after medication initiation. Women aged 55 years or older seeking treatment for OAB and opting for anticholinergic therapy were recruited. Baseline cognitive function was assessed via the Hopkins Verbal Learning Test-Revised Form (HVLT-R) [and its five subscales], the Orientation, Memory & Concentration (OMC) short form, and the Mini-Cog evaluation. After initiation of trospium chloride extended release, cognitive function was reassessed at Day 1, Week 1, Week 4 and Week 12. Bladder function was assessed via three condition-specific quality-of-life questionnaires. Secondary outcomes included change in bladder symptoms, correlation between cognitive and bladder symptoms, and overall medication compliance. The main outcome measure was change in HVLT-R score at Week 4 after medication initiation, compared with baseline (pre-medication) score. RESULTS Of 50 women enrolled, 35 completed the assessment. The average age was 70.4 years and 77.1% had previously taken anticholinergic medication for OAB. At enrollment 65.7% had severe overactive bladder and 71.4% had severe urge incontinence. Cognitive function showed an initial decline on Day 1 in HVLT-R total score (p = 0.037), HVLT-R Delayed Recognition subscale (p = 0.011) and HVLT-R Recognition Bias subscale (p = 0.01). At Week 1 the HVLT-R Learning subscale declined from baseline (p = 0.029). All HVLT-R scores normalized by Week 4. OMC remained stable throughout. The Mini-Cog nadired at a 90.9% pass rate at Week 4. OAB symptoms did not improve until Week 4, based on questionnaire scores (p < 0.05). CONCLUSION Cognitive function exhibited early changes after initiation of trospium chloride but normalized within 4 weeks. Cognitive changes occurred weeks prior to OAB symptom improvement. Surveillance for cognitive changes with anticholinergic use should be part of OAB management.

The Effect of Age on Postoperative Morbidity in Women Undergoing Urogynecologic Surgery.

Objectives The objectives of this study were to estimate the effect of older age on postoperative morbidity and to assess other factors associated with postoperative complications after urogynecologic surgery. Methods We conducted a retrospective cohort study of 508 women who underwent pelvic floor reconstructive surgery between March 2011 and June 2013. Our 2 cohorts were based on age—women younger than 65 years and women aged 65 years or older. Our primary outcome was clinically significant postoperative complications defined as Dindo-Clavien grade greater than or equal to 2. We compared the risk of postoperative morbidity between the cohorts and constructed a logistic regression analysis to adjust for potential confounders. Results Of the 508 patients, 300 (59.1%) were in the younger cohort and 208 (40.9%) were in the older cohort. For our primary outcome, we found that older women had a significantly higher rate of clinically significant postoperative complications (12.5% vs 6.7%, P = 0.02). In a multivariate logistic regression model that included advanced prolapse, smoking status, Charlson Comorbidity Index, body mass index, and operative time, older age remained significantly associated with greater postoperative morbidity (odds ratio, 2.06; 95% confidence interval, 1.03–4.11). The length of surgery in hours was also associated with greater morbidity (odds ratio, 1.47; 95% confidence interval, 1.14–1.66). Conclusions Women aged 65 years and older who underwent urogynecologic surgery had a higher risk of clinically significant postoperative complications based on the Dindo-Clavien Scale when compared with women younger than 65 years.

Estimating the early impact of the FDA safety communication on the use of surgical mesh.

Objectives To estimate the early impact of the July 2011 Food and Drug Administration Safety Communication on the practice patterns of gynecologic surgeons using surgical mesh to manage pelvic organ prolapse (POP) and stress urinary incontinence (SUI). Methods A cross-sectional study was performed by administering a mesh usage questionnaire to physician attendees at the opening session of the American Association of Gynecologic Laparoscopists Global Congress of Minimally Invasive Gynecology in November 2011. Results Of the 827 physicians attending the opening session of the conference, 281 (34%) completed the questionnaire, 202 (72%) of whom reported performing surgery for POP and/or SUI. The respondents were attending physicians (83.4%) with at least 10 years of experience (65.7%), 136 (71.1%) identifying themselves as General Gynecology, 29 (17.3%) as Urogynecology, 13 (7.1%) as Minimally Invasive Gynecologic Surgery, and 3 (1.8%) as Urology. When compared with generalists, specialists were more likely to use mesh for abdominal (86% vs 56.3%, P < 0.001) and vaginal (65.9% vs 37.2%, P = 0.001) POP repair. Specialists reported using mesh for the anterior compartment (50% vs 28.3%, P = 0.01) and the posterior compartment (36.4% vs 12.5%, P = 0.001), and total vaginal mesh kits (13.6% vs 1.7%, P = 0.005). Respondents reported an increase in mesh use for primary abdominal POP repair (82 vs 92, P = 0.013) and a decrease in mesh use for recurrent vaginal POP repair (99 vs 75, P < 0.001), with more surgeons opting against mesh for recurrent POP (49 vs 74, P < 0.001). For patient counseling, 53.7% reported changing their methods. Conclusions In a self-selected sample of pelvic surgeons, we noted that the 2011 FDA Safety Communication had an impact, with changes in mesh usage and counseling patterns.

Short-term mesh exposure after robotic sacrocolpopexy with and without concomitant hysterectomy.

Objectives The primary objective of this study was to compare the short-term rate of mesh exposure after a robotic sacrocolpopexy (RSCP) compared with those after RSCP with a concomitant hysterectomy. Secondary objectives included a comparison of mesh exposure from total hysterectomies (TH) versus supracervical hysterectomies (SCH) and determination of risk factors for mesh exposure. Methods This was a retrospective cohort study of women who underwent RSCP between January 2009 and December 2011 at one academic center. The primary outcome was mesh exposure at 6 weeks postoperation. Subjects were divided into two groups: those with concomitant hysterectomy and those with RSCP alone. The hysterectomy group was subdivided into TH versus SCH. Mesh exposures and mesh revision procedures were identified using International Classification of Diseases-9 and CPT codes, respectively, and confirmed by chart review. Results There were 230 eligible women who underwent RSCP during the study period and were followed up at a 6-week postoperative visit; 118 (51.7%) had RSCP only and 112 (48.7%) had a concomitant hysterectomy. Of those who underwent hysterectomy, 79 patients (70.5%) had TH and 33 (29.5%) had SCH. There were nine (3.9%) mesh exposures attributed to RSCP. The difference between the RSCP + hysterectomy group and the RSCP-only group was 2.7% versus 5.1% (P = 0.50). The 2.7% of mesh exposures in the hysterectomy group were associated with TH and none with SCH, but this difference was not significant (P = 0.55). Conclusions Although mesh exposure with RSCP is low, serious morbidity can be associated with mesh use and appropriate preoperative counseling is critical.

Obstetric sphincter injury interacts with diarrhea and urgency to increase the risk of fecal incontinence in women with irritable bowel syndrome.

Objectives This study aimed to confirm that fecal urgency and diarrhea are independent risk factors for fecal incontinence (FI), to identify obstetrical risk factors associated with FI in women with irritable bowel syndrome, and to determine whether obstetric anal sphincter injuries interact with diarrhea or urgency to explain the occurrence of FI. Methods The study is a supplement to a diary study of bowel symptoms in 164 female patients with irritable bowel syndrome. Subjects completed daily bowel symptom diaries for 90 consecutive days and rated each bowel movement for stool consistency and presence of urgency, pain, and FI. All female participants from the parent study were invited to complete a telephone-administered 33-item bowel symptom and obstetric history questionnaire, which included the fecal incontinence severity index. Results Of the 164 women in the parent study, 115 (70.1%) completed the interview. Seventy-four (45.1%) reported FI on their diary including 34 (29.6%) who reported at least 1 episode per month, 112 (97.4%) reported episodes of urgency, and 106 (92.2%) reported episodes of diarrhea. The mean fecal incontinence severity index score was 13.9 (9.7). On multivariable analysis, FI was significantly associated with parity (P = 0.007), operative abdominal delivery (P = 0.049), obstetrical sphincter lacerations (P = 0.007), fecal urgency (P = 0.005), diarrhea (P = 0.008), and hysterectomy (P = 0.004), but was not associated with episiotomy, pelvic organ prolapse, or urinary incontinence. The synergistic interactions of obstetric anal sphincter laceration with urgency (P = 0.002) and diarrhea (P = 0.004) were significant risk factors for FI. Conclusions Fecal urgency and diarrhea are independent risk factors for FI, and they interact with obstetric anal sphincter laceration to amplify the risk of FI.

Diagnostic accuracy of visual urethral mobility exam versus Q-Tip test: a randomized crossover trial

OBJECTIVE The objective of the study was to compare the diagnostic accuracy of a visual urethral mobility examination (VUME) with a Q-Tip test in the assessment of urethral hypermobility. STUDY DESIGN Subjects were randomized to a VUME or Q-Tip test first, followed by the alternate assessment. Outcomes included hypermobile, not hypermobile, or indeterminate. Hypermobility was defined as 30° or greater from the horizontal. Pain perception and test preference were assessed. RESULTS For the 54 subjects, 61.1% demonstrated hypermobility on VUME vs 72.2% on the Q-Tip test (P = .39). Assessment of hypermobility was correlated between the 2 tools (ρ = 0.47, P = .001). Positive and negative predictive value, sensitivity, and specificity for VUME were 88%, 56%, 78%, and 71%, respectively, with a Q-Tip test as the reference standard. Mean pain score on visual analog scale was 0.72 for VUME and 3.15 for Q-tip test (P < .001). VUME was preferred by 83% of subjects. CONCLUSION VUME is a diagnostic alternative to the Q-Tip test for the assessment of urethral hypermobility and is preferred by subjects.

Relationship between race and abdominal anatomy: Effect on robotic port placement

Objectives We sought to characterize differences between African American women and white women in abdominal wall dimensions that could affect robotic port placement. By better understanding these differences, surgeons could assess and adjust port placement to accommodate varying abdominal wall anatomy. Methods A radiologist blinded to race-reviewed abdominal/pelvic computed tomographic scans of women aged 30 to 70 prescreened for demographic inclusion criteria. These consecutive scans were screened for radiologic exclusion criteria until 40 consecutive scans from each race were identified and included. Results Eighty of 663 patients, 40 of each race, met demographic inclusion criteria. The most common radiologic feature disqualifying the scans included absence of the xiphoid process on the scan and anterior abdominal wall deformity. Demographic variables including age, weight, height, and body mass index were similar between groups. Symphysis pubis to umbilicus measurement was shorter in the African American group (15.7 [2.1] vs 17.1 [2.0]; P < 0.001) and intra–anterior superior iliac spine distance was narrower (21.4 [1.2] vs 23.8 [2.0]; P = 0.003), creating an overall smaller lower abdomen in African American women. Total abdominal length was the same between groups (36.6 [2.6] vs 36.7 [2.8]; P = 0.851). Using linear regression, height, weight, and body mass index did not affect lower abdominal dimensions, whereas age (P < 0.001) had a significant inverse relationship with the symphysis pubis to umbilicus measurement. Conclusions Lower abdominal dimensions between races vary, with the umbilicus serving as an inconsistent landmark. Variance exists that can be attributed to racial differences. Assessment of these dimensions at the time of robotic surgery could lead to improved port spacing and therefore fewer arm collisions, improving robotic efficiency.
