The Fundamentals of Vaginal Surgery pilot study: developing, validating, and setting proficiency scores for a vaginal surgical skills simulation system.

BACKGROUND: Surgical training in the simulation lab can develop basic skills that translate to the operating room. Standardized, basic skills programs that are supported by validated assessment measures exist for open, laparoscopic, and endoscopic surgery; however, there is yet to be a nationally recognized and widely implemented basic skills program specifically for vaginal surgery. OBJECTIVE: Develop a vaginal surgical simulation system; evaluate robust validity evidence for the simulation system and its related performance measures; and establish a proficiency score that discriminates between novice and experienced vaginal surgeon performance. STUDY DESIGN: In this 3-phased study, we developed the Fundamentals of Vaginal Surgery simulation system consisting of (1) the Fundamentals of Vaginal Surgery Trainer, a task trainer; (2) a validated regimen of tasks to be performed on the trainer; and (3) performance measures to determine proficiency. In Phase I, we developed the task trainer and selected surgical tasks by performing a needs assessment and hierarchical task analyses, with review and consensus from an expert panel. In Phase II, we conducted a national survey of vaginal surgeons to collect validity evidence regarding test content, response process, and internal structure relevant to the simulation system. In Phase III, we compared performance of novice (first and second year residents) and experienced (third and fourth year residents, fellows, and faculty) surgeons on the simulation system to evaluate relevant relationships to other variables and consequences. Performance measures were analyzed to set a proficiency score that would discriminate between novice and expert (faculty) vaginal surgical performance. RESULTS: A novel task trainer and 6 basic vaginal surgical skills were developed in Phase I. In Phase II, the survey responses of 48 participants (27 faculty surgeons, 6 fellows, and 14 residents) were evaluated on the dimensions of test content, response process, and internal structure. To support evidence of test content, the participants deemed the task trainer and surgical tasks representative of intended surgical field and supportive of typical surgical actions (mean scores, 3.8-4.4/5). For response process, rater-data analysis revealed high rating variability regarding prototype color. This early evidence confirmed the value of a white prototype. For internal structure, there was high agreement among rater groups (obstetricians and gynecologists generalists vs Female Pelvic Medicine and Reconstructive Surgery specialists: interclass correlation coefficient range, 0.59-0.91; learners vs faculty interclass correlation coefficient range, 0.64-1.0). There were no differences in ratings across institution type, surgeon volume, expertise (P>.14). In Phase III, we analyzed performance from 23 participants (15 [65%] obstetricians and gynecologists residents, 3 [13%] fellows, and 5 [22%] Female Pelvic Medicine and Reconstructive Surgery faculty). Experienced surgeons scored significantly higher than novice surgeons (median, 467.5; interquartile range, [402.5-542.5] vs median, 261.5; interquartile range, [211.5-351.0]; P<.001). Based on these data, setting a proficiency score threshold at 400 results in 0% (0/6) novices attaining the score, with 100% (5/5) experts exceeding it. CONCLUSION: We present validity evidence relevant to all 5 sources which supports the use of this novel simulation system for basic vaginal surgical skills. To complement the system, a proficiency score of 400 was established to discriminate between novices and experts.

Indications for surgical intervention in a postpartum pelvic floor specialty clinic.

OBJECTIVE: To determine the prevalence and type of surgical procedures undergone by postpartum women seen in a specialty postpartum pelvic floor clinic over 11 years. METHODS: This study was a retrospective chart review of patients requiring surgical intervention within a 1-year period after their initial visit to the Michigan Healthy Healing After Delivery (MHHAD) clinic at the University of Michigan from July 2007 through January 2019. Chart review was performed to abstract demographics, obstetric data, indication for postpartum clinic visit, primary and secondary indications for surgery, and procedures performed. Descriptive analyses were used to describe the cohort. RESULTS: Of the 1138 new MHHAD patients seen during the study period, 9.1% (n = 103) underwent surgical management. Anal incontinence was the primary or secondary indication for surgery in 51.5% (n = 53) of women. The most common surgical interventions were anal sphincteroplasty (37.9%, n = 39), perineal laceration revision (33.0%, n = 34), and rectovaginal fistula repair/fistulotomy (19.4%, n = 20). Of the women who had a sphincteroplasty, 61.5% (24/39) had a prior fourth-degree perineal laceration. CONCLUSIONS: Anal sphincteroplasty was the most common surgical intervention undergone by women seen in a postpartum pelvic floor specialty clinic. Postpartum pelvic floor clinics, such as the Michigan Healthy Healing After Delivery Clinic, provide the expertise and specialized resources required to ensure the early diagnosis and treatment of pelvic floor conditions related to childbirth thus improving women's quality of life and preventing potential life-long sequelae.

Deliberate Practice: Applying the Expert Performance Approach to Gynecologic Surgical Training.

Surgical training is shifting from the historical Halstedian apprenticeship model to outcomes-based methods. Surgical residents can reach a higher level of performance when utilizing deliberate practice and the expert performance approach. This article discusses methods for implementing deliberate practice and the expert performance approach into gynecologic surgical training programs.

Do the Surgical Outcomes of Rectovaginal Fistula Repairs Differ for Obstetric and Nonobstetric Fistulas? A Retrospective Cohort Study.

OBJECTIVES: Rectovaginal fistulas can occur from both obstetric and nonobstetric (eg, inflammatory bowel disease, iatrogenic, or traumatic) etiologies. Current data on factors contributing to rectovaginal repair success or failure are limited, making adequate patient counseling difficult. Our objective was to compare outcomes of transperineal rectovaginal fistula repair performed in a single referral center on women with obstetric and nonobstetric causes. METHODS: We performed a retrospective cohort study of women who had a transperineal rectovaginal fistula repair performed by a urogynecologist at the University of Michigan from 2005 to 2015. Data were obtained by chart review and included demographics, medical comorbidities, fistula etiology, history of a prior fistula repair, failure of current repair, time to failure, and operative details. Repair failure was defined as fistula symptoms with presence of recurrent fistula on exam or imaging in the postoperative follow-up period. Comparisons between the obstetric and nonobstetric cohorts were performed using χ, Fisher exact, and Wilcoxon rank sum tests. Relative risks were calculated to identify predictors of failure. RESULTS: Eighty-eight women were included-53 obstetric and 35 nonobstetric fistulas. The overall fistula repair failure rate was 22.7% (n = 20). Median follow-up was 157.0 days (range, 47.5-402.0). Of all the factors, only nonobstetric etiology was significantly associated with an increased risk of repair failure (relative risk, 3.53 [range, 1.50-8.32]; P = 0.004. CONCLUSIONS: Nonobstetric rectovaginal fistulas have a nearly 4-fold increased risk of repair failure compared with obstetric fistulas. Our results will help surgeons adequately counsel patients on potential outcomes of surgical repair of obstetric versus nonobstetric rectovaginal fistulas.

Structural, functional, and symptomatic differences between women with rectocele versus cystocele and normal support.

BACKGROUND: Prolapse of the anterior and posterior vaginal walls has been generally associated with apical descent and levator ani muscle defects. However, the relative contributions of these factors to the pathophysiology of descent in the different vaginal compartments is not well understood. Furthermore, symptoms uniquely associated with prolapse in these compartments have not been well characterized. OBJECTIVES: The objectives of the study were to compare the associations between the following: (1) apical support, (2) levator ani muscles, and (3) pelvic floor symptoms in women with posterior-predominant prolapse, anterior-predominant prolapse, and normal support. STUDY DESIGN: This is a cross-sectional study with 2 case arms: 60 women with posterior prolapse, 90 with anterior prolapse, and a referent control arm with 103 asymptomatic subjects with normal support, determined from pelvic organ prolapse quantification examinations. Levator muscle defects were graded from magnetic resonance imaging. Vaginal closure forces above resting were measured with an instrumented speculum during maximal contraction. Pelvic floor symptoms were measured via the Pelvic Floor Distress Inventory-Short Form. RESULTS: Mean point C location in controls was -6.9 cm [1.5] (mean [standard deviation]); and was higher in posterior prolapse (-4.7 cm [2.7], 2.2 cm below controls) than the anterior prolapse group (-1.2 cm [4.1]; 5.6 cm below controls, P < .001 for all comparisons). Normal-appearing muscles (ie, muscle without a visible defect) occurred at similar frequencies in posterior prolapse (45%) and controls (51%, P = .43) but less often in anterior prolapse (28%, P ≤ .03 for pairwise comparisons). Major levator ani defects occurred at similar rates in women with posterior (33%) and anterior prolapse (42%, P = .27) but less often in controls (16%, P ≤ .012 for both pairwise comparisons). Similarly, there were significant differences in generated vaginal closure forces across the 3 groups, with the prolapse groups generating weaker closure forces than the control group (P = .004), but the differences between the 2 prolapse groups were not significant after controlling for prolapse size (P = .43). Pelvic floor symptoms were more severe for the posterior (mean Pelvic Floor Distress Inventory score, 129) and anterior prolapse groups (score, 128) than the controls (score, 40.2, P < .001 for both comparisons); the difference between the 2 prolapse groups was not significant (P = .83). CONCLUSION: Posterior-predominant prolapse involves an almost 3-fold less apical descent below normal than anterior-predominant vaginal prolapse. Levator ani defects and muscle impairment also have a lower impact. Pelvic floor symptoms reflect the presence and size of prolapse more than the predominant lax vaginal compartment.

Ligament shortening compared to vaginal colpopexy at the time of hysterectomy for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: The performance of a colpopexy at the time of hysterectomy for pelvic organ prolapse is a potential indicator of surgical quality. However, vaginal colpopexy has not been directly compared with the classic technique of ligament shortening and reattachment. We sought to test the null hypothesis that there is no difference in prolapse recurrence between the techniques. METHODS: We performed a retrospective chart review of 330 vaginal hysterectomies performed for prolapse, comparing symptomatic and/or anatomic recurrence rates between patients having a vaginal colpopexy (uterosacral ligament suspension or sacrospinous ligament suspension) and those having ligament shortening and reattachment. Clinically relevant variables significantly associated with recurrence in a univariate analysis were used to create a multivariable logistic regression model to predict recurrence. RESULTS: With a mean follow-up of 20 months, there was no significant difference between symptomatic and/or anatomic recurrence rates: 19.4 % of patients (41 of 211) having colpopexy vs. 11.8 % of patients (14 of 119) having ligament shortening (p = 0.07). Baseline prolapse stage was higher in patients having colpopexy (median 3, IQR 2 - 5) than in those having ligament shortening (median 2, IQR 1 - 3; p ≤ 0.0001). In the multivariable logistic regression analysis, the procedure performed was not associated with recurrence (OR 1.57, 95 % CI 0.79 - 3.12). A baseline prolapse of 4 cm or greater was associated with recurrence (OR 2.63, 95 % CI 1.32 - 5.22), as was the time since hysterectomy (OR 1.02 per month, 95 % CI 1.01 - 1.04). CONCLUSIONS: When compared with vaginal colpopexy, selective use of the ligament shortening technique at the time of vaginal hysterectomy was associated with similar rates of prolapse recurrence. Preoperative prolapse size was the factor most strongly associated with recurrence.

Patient Satisfaction With Nurse-Led Telephone Follow-up in an Ambulatory Setting.

OBJECTIVES: We studied our practice of using nurse telephone follow-up under physician direction to assess symptom improvement and patient satisfaction. METHODS: Women were recruited when their clinical care merited nurse telephone follow-up in the opinion of the attending physician. Women specified a preferred telephone number and completed a symptom questionnaire at the time of enrollment. Nursing telephone follow-up was completed at an interval prescribed by the attending physician to answer specified clinical questions. Approximately 3 months after the initial in-office visit, a satisfaction questionnaire and repeat symptom measure were mailed to the subjects. RESULTS: A convenience sample of 83 women was analyzed. Of those, 91.6% were reached by telephone, and 47.0% returned the follow-up questionnaire. Mean (SD) age was 56.8 (16.6) years (range, 20-89 years). Younger women were less likely to be able to be contacted by telephone (P = 0.02) and less likely to return the questionnaire (P = 0.02). Most common diagnoses were overactive bladder and mixed urinary incontinence. Satisfaction rates were high, and level of convenience for patients was high. Women indicated an ease of speaking over the telephone about their condition and confidence in the treatment plan. Satisfaction with telephone follow-up did not significantly differ based on age or diagnosis. CONCLUSIONS: Patient satisfaction was high for nurse telephone follow-up to replace in-office visits for selected diagnoses. This care strategy deserves further consideration for reimbursement purposes as health care evolves.

Outpatient Narcotic Use After Minimally Invasive Urogynecologic Surgery.

OBJECTIVES: To quantify outpatient narcotic use in the first 2 weeks after urogynecologic surgery. METHODS: Using a convenience sample, women who underwent minimally invasive urogynecologic surgery between May and October 2014 were contacted by telephone 2 weeks postoperatively and given a questionnaire regarding their postoperative pain experience. To quantify narcotic use, patients were asked to count the tablets remaining from their discharge narcotic prescription. Postoperative pain scores and pain expectations were also assessed. Women using more than 30 narcotics were in the top quartile for use; therefore, those using 30 or fewer versus more than 30 were compared. Logistic regression was used to identify independent factors associated with women in the top quartile for postoperative narcotic use. RESULTS: Fifty women were included in the study. Median number of narcotics used was 13 (interquartile range (IQR), 1-30) versus 40 (IQR, 35-60) prescribed. Compared to women who used 30 or fewer narcotics (n=38), those using more than 30 (n=12) more frequently were taking narcotics before surgery (13.2% vs 41.7%; P=0.03) and had a chronic pain diagnosis (15.8% vs 58.3%; P=0.003). Although pain scores were similar, women who took more than 30 narcotics more frequently reported their postoperative pain to be much worse or worse than expected (7.9% vs 33.3%; P=0.048). In logistic regression, chronic pain remained the only factor associated with using more than 30 narcotics (odds ratio, 7.36; 95% confidence interval, 1.00-54.03; P=0.0496). CONCLUSIONS: Women used one third of the narcotics they were prescribed after minimally invasive urogynecologic surgery. These data may be useful for establishing narcotic prescription guidelines.

Colovaginal Fistulas: Presentation, Evaluation, and Management.

OBJECTIVE: The objective of this study was to review a single institution's experience with colovaginal fistulas to provide guidance toward identification and management of this problem. METHODS: Patients with colovaginal fistulas treated by 2 senior surgeons between January 1, 1990, and June 31, 2011, were identified. A retrospective chart review was then performed to determine presenting characteristics and history, evaluation for the fistulas, and treatment outcomes. RESULTS: Nineteen patients were identified. The mean age was 63.5 years and median parity of 2. 37% complained of flatus per vagina, 89% reported stool per vagina, and 68% noted vaginal discharge. Ninety-five percent had previously undergone hysterectomy. The fistulas were identified at the left vaginal apex in 90% of the subjects. Self-reported history and/or operative findings suggested diverticulitis as the most common etiology (79% of the subjects). All subjects underwent sigmoid resection with primary anastomosis, with complete symptom resolution in 84%. CONCLUSIONS: Patients with colovaginal fistulas commonly present for primary evaluation by gynecologists. A triad of symptoms and history should trigger a high index of suspicion for colovaginal fistulas: (1) complaints of stool or flatus per vagina or foul-smelling vaginitis resistant to treatment, (2) previous hysterectomy, and (3) history of diverticulitis. The fistulas can often be visualized on speculum examination at the left vaginal apex. Rolling the patient from left to right lateral decubitus positions during a contrast enema study can improve its sensitivity. Repair of colovaginal fistulas via rectosigmoid resection and primary reanastomosis is safe and effective. We recommend multidisciplinary management involving colorectal surgery and gynecology.

Universal Cystoscopy After Benign Hysterectomy: Examining the Effects of an Institutional Policy.

OBJECTIVE: To evaluate the association between a universal cystoscopy policy at the time of benign hysterectomy and the detection of urologic injuries. METHODS: This is a retrospective cohort study at a tertiary care academic center where a policy of universal cystoscopy at the time of benign hysterectomy was instituted on October 1, 2008. Benign hysterectomies performed from March 3, 2006, to September 25, 2013, were included and dichotomized into preuniversal and postuniversal cystoscopy groups. Medical records were reviewed for baseline and perioperative characteristics, cystoscopy use, and urologic injuries related to hysterectomy. Urologic injuries were identified by using a search engine and a departmental quality improvement database. RESULTS: Two thousand nine hundred eighteen hysterectomies were identified during the study time period, 96 of which were excluded for indications of abdominopelvic cancers and peripartum indications. Therefore, 973 women were in the preuniversal cystoscopy group and 1,849 were in the postuniversal cystoscopy group. Thirty-six percent (347/973, 95% confidence interval [CI] 32.8-38.8%) and 86.1% (1,592/1,849, 95% CI 84.5-87.7%) of patients underwent cystoscopy prepolicy and postpolicy, respectively. The urologic injury rates were 2.6% (25/973, 95% CI 1.6-3.6%) and 1.8% (34/1,849, 95% CI 1.2-2.5%) in the prepolicy and postpolicy groups, respectively. Delayed urologic injuries decreased significantly (0.7% [7/973], 95% CI 0.3-1.2% compared with 0.1% [2/1,849], 95% CI 0.0-0.3%). Of the nine patients with delayed injuries, four had normal intraoperative cystoscopy findings and five had no cystoscopy performed. CONCLUSION: The practice of universal cystoscopy at the time of hysterectomy for benign indications is associated with decreased delayed postoperative urologic complications.

Defining Patient Knowledge and Perceptions of Vaginal Pessaries for Prolapse and Incontinence.

OBJECTIVE: The aim of this study was to define patient knowledge and perceptions of pessaries to identify barriers to care and inform physician counseling efforts. METHODS: An anonymous survey was distributed to a convenience sample of new patients presenting to the urogynecology clinic at a single academic medical center. Data analysis was performed using standard bivariate and logistic regression models. RESULTS: A total of 254 women completed the survey. Only half of respondents indicated prior knowledge of pessaries. The most common source of prior knowledge was a physician or other health care provider (100/130, 76.9%); comparatively few women had heard about pessaries from any other source. Patients presented with a negative view of pessaries, 3.6 ± 2.2 on a 0- to 10-point Likert scale, and only a third of patients indicated they would consider pessary use as a treatment option for their condition. On multivariable logistic regression, having previously seen a gynecologist (P = 0.03) and a lower level of education (P = 0.05) independently predicted aversion to pessary use. CONCLUSIONS: Only half of patients presenting to a referral-based practice had previous knowledge of vaginal pessaries. Few patients had heard about pessaries from any source other than a physician or other health care provider. Patients presented with a negative impression of pessaries and a high level of aversion to pessary use. Patients who indicated they would decline pessary use reported a lower level of education and were more likely to have previously seen a gynecologist for evaluation of their condition. These data may inform physician counseling efforts.

A posterior anal sling for fecal incontinence: results of a 152-patient prospective multicenter study.

BACKGROUND: The transobturator posterior anal sling (TOPAS) system is a posterior anal sling that is a minimally invasive, self-fixating polypropylene mesh intended to treat fecal incontinence (FI) in women who have failed conservative therapy. OBJECTIVE: We are reporting 1-year outcome in a prospective, multicenter study under investigational device exemption, evaluating this new treatment modality. STUDY DESIGN: A total of 152 women were implanted with the TOPAS system at 14 centers in the United States. FI was assessed preoperatively and at the 12-month follow up with a 14-day bowel diary, Cleveland Clinic Incontinence Scores, and FI Quality of Life questionnaires. Treatment success was defined as reduction in number of FI episodes of ≥50% compared to baseline. Missing bowel diary data were considered treatment failures. The Wilcoxon signed rank test was used to compare changes observed at 12 months vs baseline. RESULTS: Mean age was 59.6 years old (SD 9.7). The mean duration of FI was 110 mo (range 8-712) months. Mean length of the implant procedure was 33.4 (SD 11.6) minutes. Mean EBL was 12.9 (SD 10.5) mL. Average follow-up was 24.9 months. At 12 months, 69.1% of patients met the criteria for treatment success, and 19% of subjects reported complete continence. FI episodes/wk decreased from a median of 9.0 (range 2-40) at baseline to 2.5 (range 0-40) (P < .001). FI days decreased from a median of 5.0 (range 1.5-7) at baseline to 2.0 (range 0-7) (P < .001) over a 7-day period. FI associated with urgency decreased from a median at baseline of 2.0 (range 0-26) to 0 (range 0-14.5) (P < .001). The mean Cleveland Clinic Incontinence Scores decreased from 13.9 at baseline to 9.6 at 12 months (P < .001). FI Quality of Life scores for all 4 domains improved significantly from baseline to 12 months (P < .001). A total of 66 subjects experienced 104 procedure- and/or device-related adverse events (AEs). Most AEs were short in duration and 97% were managed without therapy or with nonsurgical interventions. No treatment-related deaths, erosions, extrusions, or device revisions were reported. The most common AE categories were pelvic pain (n = 47) and infection (n = 26). Those subjects experiencing pelvic pain had a mean pain score (0-10 scale, 0 = no pain) during the 12-month follow-up of 1.2 (SD 2.4). CONCLUSION: The TOPAS system provides significant improvements in FI symptoms and quality of life with an acceptable AE profile and may therefore be a viable minimally invasive treatment option for FI in women.

Surgical site infection following hysterectomy: adjusted rankings in a regional collaborative.

BACKROUND: Surgical site infection after abdominal hysterectomy (defined as open and laparoscopic) will be a metric used to rank and penalize hospitals in the Hospital Acquired Condition Reduction program. Hospitals whose Hospital Acquired Condition Reduction score places them in the bottom quartile will lose 1% of reimbursement from the Centers of Medicaid and Medicare Services. OBJECTIVES: The objectives of this analysis were to develop a risk adjustment model for surgical site infection after hysterectomy, to calculate adjusted surgical site infection rates, to rank hospitals by the predicted to expected (P/E) ratio, and to compare the number of outlier hospitals with the number in the bottom quartile. STUDY DESIGN: This was a retrospective analysis of hysterectomies from the Michigan Surgical Quality Collaborative performed between July 1, 2012, and July 1, 2014. Superficial, deep, and organ space surgical site infections were categorized according to Centers for Disease Control and Prevention criteria. Deep and organ space surgical site infections were considered 1 group for this analysis because these spaces are contiguous after hysterectomy. Hospital rankings focused on deep/organ space events because the Hospital Acquired Condition Reduction program will rank and penalize based on them, not superficial surgical site infection. Hierarchical multivariable logistic regression, which takes into account hospital effects, was used to identify risk factors for all surgical site infections and deep/organ space surgical site infections. Predicted to expected ratios for deep surgical site infection were calculated for each hospital and used to determine hospital rankings. Outliers were defined as those hospitals who predicted to expected confidence intervals crossed the reference line of 1. The number of outlier hospitals was compared with the number in the bottom quartile. RESULTS: The overall surgical site infection rate following hysterectomy was 2.1% (351 of 16,548). Deep/organ space surgical site infection accounted for 1.0% (n = 167 of 16,548). Deep surgical site infection was associated independently with younger age, longer surgical times, gynecological cancer, and open hysterectomy. There was a marginal association with blood transfusion. After risk adjustment of rates and ranking by the predicted to expected ratio, there was a change in quartile rank for 42.8% of hospitals (21 of 49). Two hospitals were identified as outliers. However, if the bottom quartile was identified, as called for by the Hospital Acquired Condition Reduction program, 10 additional hospitals would be targeted for a penalty. Hospitals with < 300 beds were most likely to see their quartile rank worsen, whereas those > 500 beds were most likely to see their quartile rank improve (P = .01). CONCLUSION: After adjusting for patient-related factors and site variation, more than 40% of hospitals will change quartile rank with respect to deep surgical site infection. Identifying a quartile of hospitals that are statistically different from others was not feasible in our collaborative because only 2 of 12 hospitals were outliers. These findings suggest that under the Hospital Acquired Condition Reduction program, many hospitals will be unjustly penalized.

Removal of normal ovaries in women under age 51 at the time of hysterectomy.

OBJECTIVE: Despite recommendation for ovarian conservation in low-risk, premenopausal women, bilateral oophorectomy is often performed. The purpose of this study was to investigate factors associated with removal of normal ovaries at the time of hysterectomy for benign indication in women age <51 years. STUDY DESIGN: Demographics, indication for surgery, adnexal pathology, and surgical approach were analyzed for hysterectomies from a voluntary, statewide surgical quality collaborative. Cases were excluded if the surgical indication was cancer, pelvic mass, or obstetric, or if age was >50 years. Cases were categorized according to pathology of the adnexal specimen as cancer, benign findings, normal ovary, or no ovarian specimen. Variables including demographics, medical comorbidities, and surgical characteristics were analyzed to identify characteristics associated with oophorectomy at the time of hysterectomy. A logistic regression model was then developed to identify factors independently associated with removal of normal ovaries. RESULTS: A total of 6789 subjects were included. Oophorectomy was performed in 44.2% of women (n = 3002). In all, 23.1% (n = 1565) had normal ovaries on pathology. Incidental ovarian cancer was found in 0.2% (n = 12), and benign pathology was found in 21% (n = 1425). Removal of normal ovaries was less likely when the surgical approach was vaginal (18%) as opposed to laparoscopic (23.1%) or abdominal (26.0%). With adjustment, abdominal (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.43-2.09]) and laparoscopic (OR, 1.27; 95% CI, 1.08-1.50) approach showed significantly higher odds of normal ovary removal compared to vaginal hysterectomy. Age 46-50 years was also significantly associated (OR, 1.78; 95% CI, 1.53-2.07). Surgical indications associated with increased oophorectomy with normal resultant pathology were family history of cancer (OR, 3.09; 95% CI, 1.94-4.94), endometrial hyperplasia (OR, 2.36; 95% CI, 1.38-4.01), endometriosis (OR, 2.01; 95% CI, 1.30-3.09), and cervical dysplasia (OR, 1.91; 95% CI, 1.12-3.28). CONCLUSION: Removal of histologically normal ovaries is performed in nearly 1 of every 4 women age <51 years undergoing hysterectomy for benign indications. Factors associated include age closer to menopause, surgical approach, and certain indications for hysterectomy. Reducing the rate of elective oophorectomy in low-risk, premenopausal women may be a target for quality improvement efforts. Future work should continue to evaluate this practice, associated factors, physician counseling, and patient decision-making.

A multi-compartment 3-D finite element model of rectocele and its interaction with cystocele.

We developed a subject-specific 3-D finite element model to understand the mechanics underlying formation of female pelvic organ prolapse, specifically a rectocele and its interaction with a cystocele. The model was created from MRI 3-D geometry of a healthy 45 year-old multiparous woman. It included anterior and posterior vaginal walls, levator ani muscle, cardinal and uterosacral ligaments, anterior and posterior arcus tendineus fascia pelvis, arcus tendineus levator ani, perineal body, perineal membrane and anal sphincter. Material properties were mostly from the literature. Tissue impairment was modeled as decreased tissue stiffness based on previous clinical studies. Model equations were solved using Abaqus v 6.11. The sensitivity of anterior and posterior vaginal wall geometry was calculated for different combinations tissue impairments under increasing intraabdominal pressure. Prolapse size was reported as pelvic organ prolapse quantification system (POP-Q) point at point Bp for rectocele and point Ba for cystocele. Results show that a rectocele resulted from impairments of the levator ani and posterior compartment support. For 20% levator and 85% posterior support impairments, simulated rectocele size (at POP-Q point: Bp) increased 0.29 mm/cm H2O without apical impairment and 0.36 mm/cm H2O with 60% apical impairment, as intraabdominal pressures increased from 0 to 150 cm H2O. Apical support impairment could result in the development of either a cystocele or rectocele. Simulated repair of posterior compartment support decreased rectocele but increased a preexisting cystocele. We conclude that development of rectocele and cystocele depend on the presence of anterior, posterior, levator and/or or apical support impairments, as well as the interaction of the prolapse with the opposing compartment.

Experiences during the first four years of a postpartum perineal clinic in the USA.

OBJECTIVE: To assess the characteristics of patients seen at a postpartum perineal clinic in the USA during the first 4 years of its existence, and to identify factors contributing to the clinic's success. METHODS: In a retrospective study, the charts of patients presenting to the clinic between July 1, 2007, and June 30, 2011, were reviewed for presenting complaint, findings, treatment, number of visits, and referral source. Strategies that led to successful clinic implementation were reviewed. RESULTS: A total of 247 patients were seen during the 4-year period. Indications for referral included lacerations, pain, urinary and fecal incontinence, and fistulas. The most common referral indication was a third- or fourth-degree laceration, which affected 154 (62.3%) patients. Overall, 53 (21.5%) patients required a procedure, of whom 20 (8.1%) underwent surgery. Most women were counseled about pelvic floor exercises, and 39 (15.8%) were referred for pelvic floor physical therapy. Nurse-led triage, patient education, and follow-up were key to the success of the program. CONCLUSION: The postpartum perineal clinic is sustainable and offers an opportunity for early assessment and treatment of pelvic floor dysfunction after a complicated vaginal delivery.

Symptom resolution after operative management of complications from transvaginal mesh.

OBJECTIVE: Complications from transvaginal mesh placed for prolapse often require operative management. The aim of this study is to describe the outcomes of vaginal mesh removal. METHODS: A retrospective review of all patients having surgery by the urogynecology group in the department of obstetrics and gynecology at our institution for a complication of transvaginal mesh placed for prolapse was performed. Demographics, presenting symptoms, surgical procedures, and postoperative symptoms were abstracted. Comparative statistics were performed using the χ or Fisher's exact test with significance at P<.05. RESULTS: Between January 2008 and April 2012, 90 patients had surgery for complications related to vaginal mesh and 84 had follow-up data. The most common presenting signs and symptoms were: mesh exposure, 62% (n=56); pain, 64% (n=58); and dyspareunia, 48% (n=43). During operative management, mesh erosion was encountered unexpectedly in a second area of the vagina in 5% (n=4), in the bladder in 1% (n=1), and in the bowel in 2% (n=2). After vaginal mesh removal, 51% (n=43) had resolution of all presenting symptoms. Mesh exposure was treated successfully in 95% of patients, whereas pain was only successfully treated in 51% of patients. CONCLUSION: Removal of vaginal mesh is helpful in relieving symptoms of presentation. Patients can be reassured that exposed mesh can almost always be successfully managed surgically, but pain and dyspareunia are only resolved completely in half of patients. LEVEL OF EVIDENCE: III.

Long-term patient satisfaction with michigan four-wall sacrospinous ligament suspension for prolapse.

OBJECTIVE: To describe patient satisfaction after Michigan four-wall sacrospinous ligament suspension for prolapse and identify factors associated with satisfaction. METHODS: Four hundred fifty-three patients were asked to rate their satisfaction with surgery and complete validated quality-of-life instruments. Postoperative support was extracted from the medical record and assessed when possible. Factors independently associated with patients who were "highly satisfied" were identified with multivariable logistic regression. RESULTS: Sixty-two percent (242/392) reported how satisfied they were 8.0±1.7 years later. Fifty-seven percent had failed prior prolapse surgery, and 56% had a preoperative prolapse 4 cm or greater beyond the hymen. Ninety percent were satisfied; 76% were "completely" or "very" satisfied and they were considered "highly satisfied" for analysis. Fourteen percent reporting being "moderately" satisfied and they were considered among those "less satisfied." Women with lower scores on the postoperative Pelvic Floor Distress Inventory-20 were more likely to be "highly satisfied." Postoperative anatomic data were available for 67% (162/242) and vaginal support was observed at or above the hymen in 86%. Women with preoperative Baden Walker grade 3 or 4 prolapse were more likely than those with grade 2 prolapse to be "highly satisfied." Women with advanced postoperative prolapse (grade 3 or 4) were less likely and those with grade 2 support were as likely to be "highly satisfied" as those with grade 0 or 1 support. CONCLUSION: The Michigan four-wall sacrospinous ligament suspension is an anatomically effective approach to vault suspension with a high rate of long-term patient satisfaction. Postoperative vaginal support at the hymen does not negatively affect patient satisfaction. LEVEL OF EVIDENCE: III.

Defining patients' knowledge and perceptions of vaginal mesh surgery.

OBJECTIVE: Given recent government investigations and media coverage of the controversy regarding mesh surgery, we sought to define patients' knowledge and perceptions of vaginal mesh surgery. STUDY DESIGN: An anonymous survey was distributed to a convenience sample of new patients at urogynecology and female urology clinics at a single medical center during April to June 2012. The survey assessed patients' demographics, information sources, and beliefs and concerns regarding mesh surgery. The Fisher's exact test was used to identify predictors of patients' beliefs regarding mesh. Logistic and linear regressions were used to identify predictors of aversion to surgery and higher concern regarding future surgery. RESULTS: One hundred sixty-four women completed the survey; 62.2% (102/164) indicated knowledge of mesh surgery for prolapse and/or incontinence and were included in subsequent analyses. The mean ± SD age was 58.0 ± 12.5 years, and 24.5% reported prior mesh surgery. The most common information source was television commercials (57.8%); only 23.5% of the women reported receiving information from a medical professional. Participants indicated the following regarding vaginal mesh: class-action lawsuit in progress (55/102 [54.0%]), causes pain (47/102 [47.1%]), possibility of rejection (35/102 [34.3%]), can cause bleeding and become exposed vaginally (30/102 [29.4%]), and should be removed owing to recall (28/102 [27.5%]). Of these women, 22.1% (19/86) indicated they would not consider mesh surgery. On multivariable logistic regression, level of concern, information from friends/family, and knowledge of class-action lawsuit predicted aversion to mesh surgery. CONCLUSION: Nearly two thirds of new patients had knowledge of vaginal mesh surgery. We identified considerable misinformation and aversion to future mesh surgery among these women.

Pathologic evaluation of explanted vaginal mesh: interdisciplinary experience from a referral center.

OBJECTIVES: In light of vaginal mesh safety concerns, we reviewed our institutional experience with analytic processes and pathologic findings of explanted vaginal mesh to identify problems and opportunities to facilitate improved documentation and research. METHODS: We reviewed gross and microscopic pathology reports and archival slides of explanted mesh specimens from January 2010 through February 2012. Specimen requisition clinical history, number of mesh specimens per case, and type of examination (gross or histologic) were abstracted from pathology records using the initial search word "mesh". RESULTS: One hundred two cases were reviewed. Explanted mesh specimens included tissue in 97%. Forty-eight percent of these cases were submitted for histopathologic evaluation (as opposed to gross examination only). Specimen requisitions listed clinical history as pain (28.4%), vaginal mesh erosion (24.5%), erosion (17.6%), urinary retention (5.9%), and infection (2.9%). When no history was provided (24.5%), the case was more frequently submitted for histologic examination (74% vs 41%, P = 0.05). In all but 2 cases, the mesh material was polypropylene; no requisition mentioned this information. Gross descriptions of mesh varied significantly; in 18% of the cases, mesh was inaccurately described as "metallic". No cases of neoplasm were diagnosed histologically; all tissue diagnoses described benign reactive processes. CONCLUSIONS: Our experience suggests that either gross or histopathologic examination is appropriate for mesh explants. Documentation of clinical history, mesh product, and material was frequently incomplete and associated with increased submission of tissue for histologic examination and inaccurate gross impression of material type. We recommend improved documentation to aid pathologic examination and enable future pathophysiologic study of mesh complications.
