Pudendal Nerve Block Analgesia at the Time of Vaginal Surgery: A Randomized, Double-Blinded, Sham-Controlled Trial.

IMPORTANCE: Effective opioid-sparing postoperative analgesia requires a multimodal approach. Regional nerve blocks augment pain control in many surgical fields and may be applied to pelvic floor reconstruction. OBJECTIVE: This study aimed to evaluate the impact of pudendal nerve block on postoperative pain control and opioid consumption after vaginal surgery. STUDY DESIGN: In this randomized, double-blind, sham-controlled trial, we enrolled women undergoing pelvic reconstruction, excluding patients with chronic pelvic pain or contraindications to nonnarcotic analgesia. Patients were randomized to transvaginal pudendal nerve block (9 mL 0.25% bupivacaine and 1 mL 40 mg/mL triamcinolone) or sham injection (10 mL normal saline). Primary outcomes were pain scores and opioid requirements. Sixty patients were required to show a 20-mm difference on a 100-mm visual analog scale (VAS). RESULTS: We randomized 71 patients: 36 pudendal block and 35 sham. Groups were well matched in baseline characteristics and surgery type. Prolapse repairs were most common (n = 63 [87.5%]), and there was no difference in anesthetic dose or operative time. Pain scores were equivalent in the postanesthesia care unit (mean VAS, 53.1 [block] vs 56.4 [sham]; P = 0.517) and on postoperative day 4 (mean VAS, 26.7 [block] vs 35.5 [sham]; P = 0.131). On postoperative day 1, the intervention group reported less pain, but this did not meet our 20 mm goal for clinical significance (mean VAS, 29.2 vs 42.5; P = 0.047). A pudendal block was associated with lower opioid consumption at all time points, but this was not statistically significant. CONCLUSIONS: Surgeon-administered pudendal nerve block at the time of vaginal surgery may not significantly improve postoperative pain control or decrease opioid use.

Geometric analysis of the urethral-vaginal interface curvature in women with and without stress urinary incontinence: A pilot magnetic resonance imaging study.

AIMS: To evaluate differences in the curvature of the urethral-vaginal interface in women with and without stress urinary incontinence (SUI) using geometric morphometric analysis techniques. METHODS: We conducted a pilot case-control study using magnetic resonance imaging (MRI) scans of 18 women with and without SUI. The urethral-vaginal interface at the level of the mid-urethra was fitted with a second-order polynomial regression. The chord length and chord-to-vertex length of the resulting parabolic curve were used to calculate the arc length and radius of a circular arc fitted to the interface curvature. Demographic characteristics and Pelvic Organ Prolapse Quantification (POP-Q) parameters were collected. Subjects were stratified by those with and without SUI, as well as by those with and without anterior wall prolapse beyond 2 cm proximal to the hymen (Aa > -2 cm). RESULTS: The radius of the urethral-vaginal interface curvature was not found to be different between subjects with and without SUI (8.8 vs. 9.2 mm, p = 0.53); however, this value was smaller in subjects with Aa > -2 (8.4 vs. 11.9 mm, p = 0.03). The chord length, chord-to-vertex length, and arc length comprising the urethral-vaginal interface curvature were similar between subjects with and without SUI, and between subjects with and without Aa > -2 cm (p > 0.05 for all). CONCLUSIONS: In this pilot study population, the radius of the urethral-vaginal interface curvature at the mid-urethra was smaller among women with anterior vaginal wall prolapse beyond 2 cm proximal to the hymen. A difference in the urethral-vaginal interface curvature among women with and without SUI was not found.

Apical suspension is underutilized for repair of stage IV pelvic organ prolapse: an analysis of national practice patterns in the United States.

INTRODUCTION AND HYPOTHESIS: Support of the vaginal apex is paramount for a durable repair of pelvic organ prolapse (POP). Our aim is to assess national utilization of apical suspension procedures for the surgical treatment of complete POP. We hypothesize that there might be a high rate of apical suspension with advanced prolapse. METHODS: The 2006-2016 National Surgical Quality Improvement Program database was queried for a primary postoperative diagnosis of complete POP. The primary outcome was type of repair. Secondary outcomes included patient characteristics associated with apical suspension or colpocleisis. Procedures were delineated using CPT codes. Chi-squared and multivariate logistic regression analyses were used to evaluate factors associated with repair type. RESULTS: A total of 2,784 women underwent surgery for complete POP with a mean age of 64.6 ± 11.0 years. Overall, 1,300 (46.7%) patients underwent apical suspension: 487 sacrocolpopexies (17.5%), 428 extraperitoneal suspensions (15.4%), and 391 uterosacral suspensions (14.0%). 5.2% (144) underwent colpocleisis, and 47.5% (1,332) of women had a concurrent hysterectomy (CH). With CH, 38.6% (502) had apical suspension or colpocleisis versus 69.5% (940) of post-hysterectomy cases. On logistic regression, CH was inversely associated with apical suspension (adjusted odds ratio [aOR] 0.37, CI 0.32-0.44, p < 0.001). Colpocleisis was associated with older age (aOR 4.9 per 10 years, CI 3.8-6.3, p < 0.001), post-hysterectomy surgery (aOR 0.23, CI 0.1-0.4, p < 0.001 for CH), and higher comorbidity index (OR 1.7, CI 1.1-2.6, p = 0.009). Complication rates are similar with and without apical suspension (8.2% versus 7.0%, p = 0.269). CONCLUSIONS: During surgery for complete POP, an apical suspension procedure is performed in 46.7% of patients and is more common post-hysterectomy.

Factors Influencing Selection of Concomitant Total Versus Supracervical Hysterectomy at the Time of Sacrocolpopexy and Associated Perioperative Outcomes.

OBJECTIVES: The objective of this study was to describe national practice patterns of hysterectomy type performed with concurrent sacrocolpopexy and determine clinical factors associated with surgical route. METHODS: We used the National Surgical Quality Improvement Program database with hysterectomy data for this retrospective cohort study. We identified sacrocolpopexy cases from 2014 to 2016 with concurrent hysterectomy and stratified patients into supracervical hysterectomy (SCH) or total hysterectomy (TH). As a secondary analysis, we compared the laparoscopic subset of cases. We performed χ2 and backward stepwise logistic regression analyses to identify factors associated with hysterectomy type and compare complication rates. RESULTS: A total of 4,615 women underwent SCP with hysterectomy: 55.8% TH and 44.2% SCH. Mean ± SD age was 56.5 ± 11.7 years. Gynecologists represent 96.3% of surgeons; 51.2% were urogynecologists. Urogynecologists were more likely than generalists to perform SCH (58.4% vs 41.6%, P < 0.001). Total hysterectomy was associated with younger age (adjusted odds ratio [aOR], 0.98 per year [0.97-0.99]), greater uterine weight (aOR, 1.05 per 10 g [1.03-1.06]), and non-Caucasian race (aOR, 0.73 [0.58-0.92]). Complication rates were equivalent between hysterectomy type (SCH, 6.2% vs TH, 6.2%; P = 0.956). Laparoscopy was used for 84.4% of surgical procedures. In this subgroup, TH was associated with greater uterine weight (aOR, 1.06 per 10 g [1.04-1.08]) and younger age (aOR, 0.97 per year [0.96-0.98]). Complication rates were similar (SCH, 5.1% vs TH, 5.0%; P = 0.824). CONCLUSIONS: At the time of sacrocolpopexy, TH is more common than SCH and is associated with younger age and greater uterine weight, although urogynecologists more commonly perform SCH. The overall risk of complications was low and similar between hysterectomy type.

Patient Preferences and Knowledge Regarding Hysterectomy: A Study from the Fellows' Pelvic Research Network (FPRN)®.

OBJECTIVE: The purpose of this study was to describe preference for and knowledge of hysterectomy routes in women presenting to urogynecology/gynecology clinics throughout the United States and to determine association with health literacy. Our primary aim was preference for hysterectomy route, and secondary aims were knowledge of basic pelvic structures and function, knowledge of various hysterectomy routes, and baseline health literacy level. METHODS: This multicenter, cross-sectional study was conducted through the Fellows' Pelvic Research Network. Patients' preference and knowledge for hysterectomy routes were assessed at initial presentation to the urogynecology/gynecology clinic with an anonymous, voluntary, self-administered questionnaire along with a validated health literacy test (Medical Term Recognition Test). RESULTS: Two hundred four women participated. Forty-five percent of patients were unsure which hysterectomy modality they would choose. Of patients who selected a preferred modality, 50% selected laparoscopic and 33% selected vaginal. Patients indicated that safety was considered highest priority when selecting route. The mean score for "knowledge about gynecology/hysterectomy" was 68%, with the high literacy group scoring higher compared with the low health literacy group (70% vs 60.1%, P = 0.01). More than 50% of patients incorrectly answered knowledge questions related to vaginal hysterectomy. Majority of the respondents had high health literacy (79.4%). CONCLUSIONS: Patients prefer laparoscopic hysterectomy approach, although have limited understanding of vaginal hysterectomy. Higher health literacy levels are associated with increased knowledge of gynecology and hysterectomy routes, but were not found to influence patient preference for hysterectomy route. Overall, patients have limited knowledge of vaginal hysterectomy.

Cystoscopy with antibiotic irrigation during pelvic reconstruction and minimally invasive gynecologic surgery: A double-blind randomized controlled trial.

AIMS: After pelvic reconstructive surgery, the risk of postoperative urinary tract infection (UTI) is significant; intraoperative cystoscopy may contribute to this risk. Intravesical antibiotics are used in the ambulatory setting and may be applied to the surgical arena. Our objective was to evaluate the efficacy of antibiotic irrigation during intraoperative cystoscopy to prevent postoperative UTI. METHODS: This double-blind randomized controlled trial enrolled 216 women undergoing cystoscopy with elective surgery for pelvic organ prolapse, stress urinary incontinence, or laparoscopic gynecologic surgery at an academic medical center 2016-2019. Participants were randomized to cystoscopic irrigation fluid type: normal saline (control) or 200,000 U polymyxin B + 40 mg neomycin solution in normal saline (antibiotic). Patients and providers who treated UTIs were blinded. The primary outcome was treatment of UTI within 6 weeks postoperatively, defined as positive culture or treatment for a symptomatic UTI. χ2 and multivariable logistic regression analyses were performed. RESULTS: We enrolled 216 women: 111 control (51.4%) and 105 antibiotic (48.6%). Mean age was 51.6 years. Groups were well matched in medical comorbidities and surgery type. Primary vaginal surgery was most common (n = 127, 58.8%). Overall, 10.7% of patients developed a postoperative UTI with no difference in incidence between groups: 9.9% of control (n = 11, 95% confidence interval [CI]: 4.0%-16.0%) versus 11.4% of antibiotic subjects (n = 12, 95% CI: 5.0%-18.0%), on χ2 (p = .718) and logistic regression analysis (adjusted odds ratio, 1.3; CI: 0.53-3.16; p = .569). CONCLUSION: When cystoscopy is performed during elective pelvic surgery, use of antibiotic irrigation does not impact the rate of postoperative UTI.

Adnexectomy at the time of vaginal hysterectomy for pelvic organ prolapse.

INTRODUCTION AND HYPOTHESIS: Preoperative counseling about salpingectomy with pelvic surgery is recommended by the American College of Obstetrics and Gynecology for ovarian cancer risk reduction. Our objective was to determine recent practice patterns and patient factors associated with salpingectomy with vaginal hysterectomy (VH) for pelvic organ prolapse (POP) in the USA. We hypothesize that salpingectomy might have become more common in recent years. METHODS: We queried the 2014-2016 National Surgical Quality Improvement Program database for women with a postoperative diagnosis of POP who underwent VH with any combination of pelvic reconstructive procedures. CPT codes do not differentiate salpingectomy from salpingo-oophorectomy, so subjects were stratified by whether concurrent adnexectomy was performed. Chi-squared and multivariate logistic regression analyses were used to evaluate characteristics associated with adnexectomy. Propensity score matching was utilized when evaluating postoperative complication rates. RESULTS: Of 5,344 women who underwent VH, 2019 (37.8%) had adnexectomy. Adnexectomy rate increased from 34.4% in 2014 to 46.8% in 2016 (p < 0.001). Adnexectomy rates of fellowship-trained urogynecologists and general gynecologists were similar (36.0% vs 38.8%, p = 0.197). On logistic regression analysis, patients more likely to undergo adnexectomy were < 65 years old (OR 0.844, CI 0.75-0.95, p = 0.004), had BMI <30 (OR 0.76, CI 0.68-0.86, p < 0.001), and were non-smokers (OR 0.78, CI 0.64-0.95, p = 0.016). Mean operative time was 17 min longer with adnexectomy (145 vs 128 min, p < 0.001). There were no differences in postoperative complications or reoperation rates between groups. CONCLUSIONS: Adnexectomy during VH for POP is safe and increasingly utilized by gynecology surgeons in the USA.

A novel measurement of pelvic floor cross-sectional area in older and younger women with and without prolapse.

BACKGROUND: An increase in size of the aperture of the pelvis that must be spanned by pelvic floor support structures translates to an increase in the force on these structures. Prior studies have measured the bony dimensions of the pelvis, but the effect of changes in muscle bulk that may affect the size of this area are unknown. OBJECTIVES: To develop a technique to evaluate the aperture size in the anterior pelvis at the level of the levator ani muscle attachments, and to identify age-related changes in women with and without prolapse. MATERIALS AND METHODS: This was a technique development and pilot case-control study evaluating pelvic magnetic resonance imaging from 30 primiparous women from the Michigan Pelvic Floor Research Group MRI Data Base: 10 younger women with normal support, 10 older women with prolapse, and 10 older menopausal women without prolapse. Anterior pelvic area measurements were made in a plane that included the bilateral ischial spines and the inferior pubic point, approximating the level of the arcus tendineus fascia pelvis. Measurements of the anterior pelvic area, obturator internus muscles, and interspinous diameter were made by 5 independent raters from the Society of Gynecologic Surgeons Pelvic Anatomy Group who focused on developing pelvic imaging techniques, and evaluating interrater reliability. Demographic characteristics were compared across groups of interest using the Wilcoxon rank sum test, χ2, or Fisher exact test where appropriate. Multiple linear regression models were created to identify independent predictors of anterior pelvic area. RESULTS: Per the study design, groups differed in age and prolapse stage. There were no differences in race, height, body mass index, gravidity, or parity. Patients with prolapse had a significantly longer interspinous diameter, and more major (>50% of the muscle) levator ani defects when compared to both older and younger women without prolapse. Interrater reliability was high for all measurements (intraclass correlation coefficient = 0.96). The anterior pelvic area (cm2) was significantly larger in older women with prolapse compared to older (60 ± 5.1 vs 53 ± 4.9, P = .004) and younger (60 ± 5.1 vs 52 ± 4.6, P = .001) women with normal support. The younger and older women with normal support did not differ in anterior pelvic area (52 ± 4.6 vs 53 ± 4.9, P = .99). After adjusting for race and body mass index, increased anterior pelvic area was significantly associated with the following: being an older woman with prolapse (ß = 6.61 cm2, P = .004), and interspinous diameter (ß = 4.52 cm2, P = .004). CONCLUSION: Older women with prolapse had the largest anterior area, suggesting that the anterior pelvic area is a novel measure to consider when evaluating women with prolapse. Interspinous diameter, and being an older woman with prolapse, were associated with a larger anterior pelvic area. This suggests that reduced obturator internus muscle size with age may not be the primary factor in determining anterior pelvic area, but that pelvic dimensions such as interspinous diameter could play a role. The measurements were highly repeatable. The high intraclass correlation coefficient indicates that all raters were able to successfully learn the imaging software and to perform measurements with high reproducibility.

Use of an Amplatz dilator to facilitate transrectal abscess drainage in children.

Image-guided transrectal drainage is an effective treatment option for many deep pelvic abscesses in children. Currently, a variety of imaging and catheter techniques are used to access and drain these abscesses. The present report describes an approach for introducing the transrectal catheter by using transabdominal ultrasound guidance to direct transrectal advancement of an Amplatz dilator with coaxial placement of the metal cannula and inner trocar from a pigtail catheter set, followed by placement of the pigtail catheter via Seldinger technique. This approach eliminates some of the limitations of other transrectal techniques. The present report describes a single-institutional experience with this technique in 13 patients.

Efficacy of a radiation safety education initiative in reducing radiation exposure in the pediatric IR suite.

BACKGROUND: The use of ionizing radiation is essential for diagnostic and therapeutic imaging in the interventional radiology (IR) suite. As the complexity of procedures increases, radiation exposure risk increases. We believed that reinforcing staff education and awareness would help optimize radiation safety. OBJECTIVE: To evaluate the effect of a radiation safety education initiative on IR staff radiation safety practices and patient radiation exposure. MATERIALS AND METHODS: After each fluoroscopic procedure performed in the IR suite during a 4-month period, dose-area product (DAP), fluoroscopy time, and use of shielding equipment (leaded eyeglasses and hanging lead shield) by IR physicians were recorded. A lecture and article were then given to IR physicians and technologists that reviewed ALARA principles for optimizing radiation dose. During the following 4 months, those same parameters were recorded after each procedure. RESULTS: Before education 432 procedures were performed and after education 616 procedures were performed. Physician use of leaded eyeglasses and hanging shield increased significantly after education. DAP and fluoroscopy time decreased significantly for uncomplicated peripherally inserted central catheters (PICC) procedures and non-PICC procedures after education, but did not change for complicated PICC procedures. CONCLUSION: Staff radiation safety education can improve IR radiation safety practices and thus decrease exposure to radiation of both staff and patients.

Embolization of an arterioportal fistula by injection of D-stat into the portal venous outflow.

Arterioportal fistulas may occur in liver transplant recipients after percutaneous biopsy. This report describes a case in which a 13-year-old liver transplant patient developed an arterioportal fistula after multiple liver biopsies and underwent coil embolization; however, at that time, there were at least two small arterial feeders that were not amenable to subselection. He later developed recurrent variceal bleeding, and repeat angiogram revealed multiple tiny serpentine feeding arteries. Because these arteries could not be subselectively catheterized, the collagen-thrombin mixture, D-Stat, was used to occlude the portal venous outflow of the arterioportal fistula. Subsequent angiography demonstrated successful complete occlusion of the arterioportal fistula.
