Multidisciplinary approach to evaluation of rectovaginal fistulas.

Thorough evaluation of a rectovaginal fistula is essential to optimize surgical repair. The underlying cause should be addressed and treated, which can affect the timing and the approach to repair. It is imperative to be well prepared because the highest chance of successful closure occurs during the initial repair attempt. Our objective was to demonstrate how multidisciplinary colorectal surgery and urogynecology teams use specific methods during the examination under anesthesia to evaluate a complex rectovaginal fistula and to optimize the surgical approach to repair. Anesthesia may be provided with monitored anesthesia care and a posterior perineal block. This pain control allows for a wide range of techniques to evaluate the fistula using anoscopy, fistula probe, hydrogen peroxide, and sigmoidoscopy. In addition, the teams show how curettage and subsequent seton placement can encourage closure by secondary intention and decrease the risk of abscess formation, respectively.

Validation of Lower Urinary Tract Symptom Questionnaire in the Transmasculine Population.

INTRODUCTION AND HYPOTHESIS: Transgender men and transmasculine individuals report a variety of lower urinary tract symptoms (LUTS), but little is known about LUTS in this population. One of the obstacles is the lack of validated questionnaires. This study was aimed at validating the International Consultation on Incontinence Questionnaire-Lower Urinary Tract Symptoms (ICIQ-LUTS), which measures filling, voiding, and incontinence symptoms, in transmasculine individuals. METHODS: This is an observational validation study that included transmasculine individuals receiving care within a single tertiary care hospital system. Construct validity was assessed by comparing the ICIQ-LUTS with severity of LUTS as measured by the Urinary Distress Inventory-Short Form (UDI-6), and concurrent validity by the association between ICIQ-LUTS and the Patient Perception of Bladder Condition (PPBC). Discriminant validity was determined by comparing ICIQ-LUTS scores in those with and those without self-reported LUTS. Spearman correlation, t test, and Kruskal-Wallis test were used for data analysis. RESULTS: A total of 131 respondents were included in the analysis. Only two individuals (1.5%) reported prior vaginectomy and/or phalloplasty. Concurrent validity was demonstrated by a significant association between ICIQ-LUTS subscales and PPBC (filling p < 0.001, voiding p < 0.001, incontinence p < 0.001). Construct validity was demonstrated by a significant correlation between ICIQ-LUTS and UDI-6 (filling ρ = 0.76, p < 0.001; voiding ρ = 0.48, p < 0.001; incontinence ρ = 0.61, p < 0.001). For discriminant validity, those with at least one self-reported LUTS had significantly higher (worse) ICIQ-LUTS subscale scores than those without self-reported LUTS. CONCLUSIONS: The ICIQ-LUTS is valid for measurement of LUTS severity in transmasculine individuals. This will be an important tool to use in future research to learn more about LUTS in this population.

Does preoperative resting genital hiatus size predict surgical outcomes?

AIM: To determine whether preoperative genital hiatus at rest is predictive of medium-term prolapse recurrence. METHODS: We conducted a retrospective study of women who underwent native tissue prolapse surgery from 2002 to 2017 with pelvic organ prolapse quantification data including resting genital hiatus at one of three time points: preoperatively, 6 weeks, and ≥1 year postoperatively. Demographics and clinical data were abstracted from the chart. Prolapse recurrence was defined by anatomic outcomes (Ba > 0, Bp > 0, and/or C ≥ -4) or retreatment. Descriptive statistics, bivariate analyses, and logistic regression analyses were performed. RESULTS: Of the 165 women included, 36 (21.8%) had prolapse recurrence at an average of 1.5 years after surgery. Preoperative resting genital hiatus did not differ between women with surgical success versus recurrence (3.5 cm [interquartile range, IQR 2.25, 4.0) vs 3.5 cm (IQR 3.0, 4.0), p = 0.71). Point Bp was greater in the recurrence group at every time point. Preoperative Bp (odds ratio [OR] 1.24, confidence interval [CI] [1.06-1.45], p = 0.01) and days from surgery (OR 1.001, CI [1.000-1.001], p < 0.01) were independently associated with recurrence. Preoperative genital hiatus at rest and strain were significantly larger among women who underwent a colpoperineorrhaphy (rest: 4.0 [3.0, 4.5] cm vs 3.5 [3.0, 4.0] cm, p < 0.01; strain: 6.0 [4.0, 6.5] cm vs 5.0 [4.0, 6.0] cm, p = 0.01). CONCLUSIONS: Preoperative genital hiatus at rest was not associated with prolapse recurrence when the majority of women underwent colpoperineorrhaphy. Preoperative Bp was more predictive of short-term prolapse recurrence. For every 1 cm increase in point Bp, there is a 24% increased odds of recurrence.

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.

Antibiotic use during repair of obstetrical anal sphincter injury: a quality improvement initiative.

OBJECTIVE: To evaluate the effects of a quality improvement initiative regarding the administration of antibiotics at the time of obstetric anal sphincter injury (OASIS) repair. METHODS: At University of Michigan-a tertiary care center in Ann Arbor, MI, USA, we implemented a quality improvement intervention aimed at administering a single dose of broad-spectrum antibiotics at the time of OASIS repair. Best practice recommendations and reminders were presented to the department. Cefazolin plus metronidazole or clindamycin plus gentamycin were the recommended antibiotics. The effects of this intervention were assessed based on a chart review of deliveries between January 4, 2014 and February 13, 2019, which included patient data both pre-initiative and post-initiative to compare the prevalence of antibiotic use at the time of OASIS repair. RESULTS: Recommended antibiotic use increased from 0.3% (1/372) pre-initiative to 75.7% (106/140) post-initiative (P < 0.001), and any antibiotic use increased from 6.5% (24/372) to 82.9% (116/140, P < 0.001). The proportion of cases complicated by wound infection/breakdown decreased by 55% after the quality improvement intervention (3.2% pre-intervention vs 1.4% post-intervention, P = 0.22). CONCLUSION: Following a departmental quality improvement intervention aimed at increasing antibiotic administration at the time of OASIS repair, antibiotic use increased 13-fold. Although underpowered to detect a significant difference in wound complications, our study showed a clinically meaningful decrease in wound infection/breakdown with antibiotic administration.

Stigma Associated With Pelvic Floor Disorders.

OBJECTIVES: Although the impact of stigma is known for women with urinary incontinence, it has not been well studied among the full spectrum of pelvic floor disorders. This study quantifies the level of stigma among women presenting for urogynecologic care and tests the hypothesis that stigma related to pelvic floor disorders results in a delay in care seeking for these problems. METHODS: Women presenting for new patient visits (N = 523) in university medical center-based urogynecology clinics completed 2 anonymous questionnaires (Stigma Scale for Chronic Illnesses 8-item version and Pelvic Floor Bother Questionnaire) before their visit. The Kruskal-Wallis test was used to compare the distributions of stigma scores. Logistic regression was used to model factors associated with a delay in seeking care. Spearman correlation was used to determine whether there was an association between stigma and bother scores. RESULTS: Median stigma score was significantly higher for those presenting with complaints of urine leakage (P = 0.015), accidental bowel leakage (P < 0.001), and constipation (P < 0.001) compared with women without these symptoms. Women presenting with accidental bowel leakage had the highest median stigma score, and those presenting with pelvic organ prolapse had the lowest. Total stigma score had a moderately positive correlation (r = 0.5, P < 0.001) with bother score. In a logistic regression model, higher stigma score was associated with a decreased likelihood of waiting 1 year or more to seek care (odds ratio = 0.92, 95% confidence interval = 0.86-0.98). CONCLUSIONS: Pelvic floor disorders carry varying levels of stigma. Women who feel more stigmatized by pelvic floor disorders seem to seek care earlier.

Genome-Wide Association Study of Pelvic Organ Prolapse Using the Michigan Genomics Initiative.

OBJECTIVES: The aim of this study was to (1) replicate previously identified genetic variants significantly associated with pelvic organ prolapse and (2) identify new genetic variants associated with pelvic organ prolapse using a genome-wide association study. METHODS: Using our institution's database linking genetic and clinical data, we identified 1,329 women of European ancestry with an International Classification of Diseases, Ninth Revision (ICD-9)/ICD-10 code for prolapse, 767 of whom also had Current Procedural Terminology (CPT)/ICD-9/ICD-10 procedure codes for prolapse surgery, and 16,383 women of European ancestry older than 40 years without a prolapse diagnosis code as controls. Patients were genotyped using the Illumina HumanCoreExome chip and imputed to the Haplotype Reference Consortium. We tested 20 million single nucleotide polymorphisms (SNPs) for association with pelvic organ prolapse adjusting for relatedness, age, chip version, and 4 principal components. We compared our results with 18 previously identified genome-wide significant SNPs from the UK Biobank, Commun Biol (2020;3:129), and Obstet Gynecol (2011;118:1345-1353). RESULTS: No variants achieved genome-wide significance (P = 5 × 10-8). However, we replicated 4 SNPs with biologic plausibility at nominal significance (P ≤ 0.05): rs12325192 (P = 0.002), rs9306894 (P = 0.05), rs1920568 (P = 0.034), and rs1247943 (P = 0.041), which were all intergenic and nearest the genes SALL1, GDF7, TBX5, and TBX5, respectively. CONCLUSIONS: Our replication of 4 biologically plausible previously reported SNPs provides further evidence for a genetic contribution to prolapse, specifically that rs12325192, rs9306894, rs1920568, and rs1247943 may contribute to susceptibility for prolapse. These and previously reported associations that have not yet been replicated should be further explored in larger, more diverse cohorts, perhaps through meta-analysis.

Review of Malpractice Litigations Involving Vesicovaginal and Rectovaginal Fistulas Following Elective Hysterectomy for Benign Indications in the United States From 1970 to 2020.

OBJECTIVE: The aims of this study were to review malpractice litigations involving vesicovaginal and rectovaginal fistulas after elective hysterectomy for benign indications in the United States and identify the most common themes in allegations by the plaintiffs and defenses by the defendants. METHODS: Using the Lexis Nexis legal database, we searched for and reviewed all U.S. malpractice litigations pertinent to this question between 1970 and 2020. RESULTS: Out of 82 cases that were identified and reviewed, 17 cases met our inclusion and exclusion criteria. These cases were decided between 1973 and 2019. Nine cases involved total abdominal hysterectomies, 1 involved total laparoscopic hysterectomy (TLH), 1 involved total vaginal hysterectomy (TVH), and the rest were not specified. Fifteen cases involved vesicovaginal fistulas and 2 involved rectovaginal fistulas. Three cases were ruled in favor of the plaintiffs, with monetary compensation ranging from $250,000 to $753,722 (approximately $364,120 to $1.8 million when adjusted for inflation), whereas 14 cases were ruled in favor of the defending surgeons. Common allegations were negligence in 15 cases and lack of informed consent in 2 cases. Factors that strengthened the defendants' arguments were thorough documentation, informed consent, and prompt referral to specialists. Intraoperative cystoscopy may have benefited in some cases. CONCLUSIONS: Thorough documentation, informed consent, and prompt referral to specialists strengthened the defendants' legal arguments. Intraoperative cystoscopy may also be beneficial.
