Utilization of Rectal Examinations Before Magnetic Resonance Defecography Studies

IMPORTANCE

More information is needed to guide referring subspecialists on the appropriate patient evaluation before magnetic resonance defecography (MRD).

OBJECTIVES

This study aimed to evaluate how often health care providers perform digital rectal examination (DRE) before ordering MRD to investigate causes of bowel and pelvic floor complaints.

STUDY DESIGN

We conducted a retrospective cohort review, including MRD performed on female patients at an integrated health care system from 2016 through 2020. The primary outcome was the presence or absence of documented rectal examination in the year before defecography by the referring provider or 6 months prior by a primary care physician or pelvic floor physical therapist. We hypothesized that the overall rate of rectal examination would be high and unaffected by the referring provider's subspecialty.

RESULTS

Three hundred-four defecography tests were performed, with 209 patients (68.8%) referred by gastroenterology providers and 95 (31.2%) from other specialties. Gastroenterologists performed DRE in 32.8% of patients, in contrast to 84.4% of patients referred by other specialties ( P < 0.001). When comparing subspecialties that most commonly refer patients for MRD (gastroenterology, colorectal surgery and urogynecology), there was a statistically significant difference between gastroenterologists and colorectal surgeons ( P < 0.001) as well as urogynecologists ( P < 0.001) but no difference in the rate of rectal examination between colorectal surgeons and urogynecologists ( P = 1.00).

CONCLUSIONS

At our single integrated health system, the rate of DRE before MRD testing varied significantly by specialty. Our findings highlight the need for better understanding of DRE utility in the algorithms for evaluation of bowel and pelvic floor disorders.

Performance of Perioperative Tasks for Women Undergoing Anti-incontinence Surgery: Developed by the AUGS Quality Improvement and Outcomes Research Network

OBJECTIVES

Surgery for the correction of stress urinary incontinence is an elective procedure that can have a dramatic and positive impact on quality of life. Anti-incontinence procedures, like inguinal hernia repairs or cholecystectomies, can be classified as high-volume/low-morbidity procedures. The performance of a standard set of perioperative tasks has been suggested as one way to optimize quality of care in elective high-volume/low-morbidity procedures. Our primary objective was to evaluate the performance of 5 perioperative tasks-(1) offering nonsurgical treatment, (2) performance of a standard preoperative prolapse examination, (3) cough stress test, (4) postvoid residual test, and (5) intraoperative cystoscopy for women undergoing surgery for stress urinary incontinence-compared among surgeons with and without board certification in female pelvic medicine and reconstructive surgery (FPMRS).

STUDY DESIGN

This study was a retrospective chart review of anti-incontinence surgical procedures performed between 2011 and 2013 at 9 health systems. Cases were reviewed for surgical volume, adverse outcomes, and the performance of 5 perioperative tasks and compared between surgeons with and without FPMRS certification.

RESULTS

Non-FPMRS surgeons performed fewer anti-incontinence procedures than FPMRS-certified surgeons. Female pelvic medicine and reconstructive surgery surgeons were more likely to perform all 5 perioperative tasks compared with non-FPMRS surgeons. After propensity matching, FPMRS surgeons had fewer patients readmitted within 30 days of surgery compared with non-FPMRS surgeons.

CONCLUSIONS

Female pelvic medicine and reconstructive surgery surgeons performed higher volumes of anti-incontinence procedures, were more likely to document the performance of the 5 perioperative tasks, and were less likely to have their patients readmitted within 30 days.

Minimally Invasive Autologous Fascia Sling at the Midurethra: A Case Series

STUDY OBJECTIVE

The primary objective was to determine the improvement in stress urinary incontinence symptoms using autologous fascia lata sling placed at the midurethra. The secondary objective was to determine the presence of leg pain after harvest of fascia lata graft.

DESIGN

Case series.

SETTING

Rural academic tertiary care center.

PATIENTS

All women who underwent an autologous fascia midurethral sling over a 1-year period between June 2019 and September 2020.

INTERVENTIONS

Autologous fascia lata midurethral sling.

MEASUREMENTS

Incontinence severity index, urodynamic distress inventory-6, and Likert pain scale.

MAIN RESULTS

Nineteen women received an autologous fascial sling at the midurethra using the described technique-16 fascia lata and 3 rectus fasciae. Mean improvement in incontinence severity index score was 6 points. Mean improvement in urodynamic distress inventory-6 and SUI subscale scores was 14 and 53, respectively, surpassing the minimally important difference for each. Median follow-up time was 9 months (range 2-16). Leg pain at the harvest site was bothersome in 1 patient beyond 6 weeks. Median time to passing voiding trial was 4 days (range 1-13 days). Four patients (21%) had postoperative voiding dysfunction, 3 of which resolved after sling loosening at a mean of 60 days after sling placement.

CONCLUSION

Midurethral autologous fascial sling placement significantly improves symptoms of SUI but carries a risk of voiding dysfunction. Harvesting fascia lata using a fascial stripper is associated with minimal postoperative morbidity.

Information Priorities for Deciding on Treatment of Pelvic Organ Prolapse

OBJECTIVE

The objective of this study was to elicit information priorities from women considering treatment for pelvic organ prolapse (POP).

STUDY DESIGN

This is a cross-sectional study of women before and after treatment of stage II or higher POP. Women were recruited either at the conclusion of their initial evaluation (before treatment) or at postoperative or pessary maintenance visits (after treatment). Women completed a written survey that used a Likert scale to rank potentially frequently asked questions (FAQs) that could be important information to use in decision making for POP.

RESULTS

Among the 100 women surveyed, 32 women wanted to pursue surgical options and 18 women wanted to pursue nonsurgical treatment options in the before treatment group. In the after treatment group, 35 women had undergone surgery and 15 women were using a pessary.Overall, women ranked FAQs about treatment success (overall Likert score, 1.11±0.35), quality of life after treatment (1.18±0.41), and complications and side effects (1.20±0.57) as the most important information when making a decision. Women were least concerned with FAQs regarding cost (2.39±1.48), impact on sexual function (2.21±1.4), and impact on hormones (2.20±1.27).

CONCLUSIONS

Women with POP identified the most important FAQs related to treatment success and complications, quality of life, and understanding how the treatment works. This information will be used to develop a comprehensive decision aid for women considering treatment options for POP.

Major postoperative complications following surgical procedures for pelvic organ prolapse: a secondary database analysis of the American College of Surgeons National Surgical Quality Improvement Program

BACKGROUND

Surgical approaches to the correction of pelvic organ prolapse include abdominal, vaginal, and obliterative approaches. These approaches require vastly different anatomical dissections, surgical techniques, and operative times and are often selected by the patient and surgeon to match preoperative multimorbidity and ability of the patient to tolerate the stress of surgery.

OBJECTIVE

We sought to describe the occurrence of postoperative complications occurring after 3 different surgical approaches to treat pelvic organ prolapse: vaginal, abdominal, and obliterative.

STUDY DESIGN

We conducted a secondary database analysis of the 2006 through 2014 American College of Surgeons National Surgical Quality Improvement Program participant use data files to analyze patients undergoing procedures for pelvic organ prolapse based on Current Procedural Terminology codes. Women were categorized into 3 surgical approaches to prolapse: vaginal, abdominal, and obliterative. Concomitant hysterectomy and sling were also examined. The primary outcome was a composite of 30-day major postoperative complications.

RESULTS

A total of 33,416 women were included in our final analysis: 24,928 vaginal procedures, 6834 abdominal (4461 minimally invasive) procedures, and 1654 obliterative procedures. Concomitant hysterectomies and slings were performed in 17,380 (52.0%) and 10,896 (32.6%) of prolapse procedures. The overall prevalence of composite 30-day major postoperative complications was 3.1% (n/N = 1028/33,416). There were 13 perioperative deaths (0.04%) with no difference in the surgical approaches (P = .55). There were no differences in major postoperative complications between vaginal and abdominal procedures (3.0% vs 3.0%; P = .71). Women undergoing obliterative procedures had an occurrence of major postoperative complications of 5.0% (n/N = 83/1654), P < .001.

CONCLUSION

The occurrence of major postoperative complications after prolapse surgery is rare. We did not find a significant difference in major postoperative complications between vaginal and abdominal surgeries for pelvic organ prolapse. In this well-characterized cohort of patients who self-selected surgical approach, women undergoing obliterative surgery had more postoperative complications, likely attributed to increased age and multimorbidity.

Functional disability among older women with fecal incontinence

OBJECTIVE

The prevalence of functional disability for basic activities of daily living (ADLs) in older women with fecal incontinence (FI) is not well characterized. Our objective was to determine the prevalence of functional disability among community-dwelling older women with FI.

STUDY DESIGN

We conducted a secondary database analysis of the 2005-2006 National Social Life, Health and Aging Project, a cross-sectional study of community-dwelling older adults that had been conducted by single in-home interviews. FI was defined as an affirmative answer to the question, "Have you lost control of your bowels (stool incontinence or anal incontinence)?" with a frequency of "at least monthly." We then examined functional status. Women were asked about 7 basic ADLs. Statistical analyses with percentage estimates and 95% confidence intervals (CIs) were performed.

RESULTS

We included 1412 women in our analysis. FI, at least monthly, was reported by 5.5% of community-dwelling older women (n = 77); 63.2% (95% CI, 50.1-76.4) of the women with FI reported difficulty or dependence with ≥1 ADLs, and 31.2% (95% CI, 18.9-43.6) of the women specifically reported difficulty or dependence with using the toilet. After adjustment for age category, race/ethnicity, education level, women with FI had 2.6 increased odds (95% CI, 1.26-5.35) of difficulty or dependence compared with women with no FI. Other significant risk factors for increased functional difficulty/dependence included obesity (body mass index, ≥30 kg/m(2)) and depressive symptoms.

CONCLUSION

Consistent with other large epidemiologic studies, we found monthly FI was reported by 5.5% of older women (n/N = 77/1412). More than 60% of community-dwelling older women with FI report functional difficulty or dependence with ≥1 ADL and specifically; more than 30% of women with FI report difficulty or dependence using/reaching the toilet. Because of the high prevalence of functional disability in older women with FI, we purpose that initial evaluation and treatment of FI may be improved by considering functional status.

Frailty, cognitive impairment, and functional disability in older women with female pelvic floor dysfunction

INTRODUCTION AND HYPOTHESIS

There is a growing body of evidence demonstrating frailty as an important predictor of surgical outcomes in older adults undergoing major surgeries. The age-related onset of many symptoms of female pelvic floor dysfunction (PFD) in women suggests that many women seeking treatment for PFD may also have a high prevalence of frailty, which could potentially impact the risks and benefits of surgical treatment options. Our primary objective was to determine the prevalence of frailty, cognitive impairment, and functional disability in older women seeking treatment for PFD.

METHODS

We conducted a cross-sectional study with prospective recruitment between September 2011 and September 2012. Women, age 65 years and older, were recruited at the conclusion of their new patient consultation for PFD at a tertiary center. A comprehensive geriatric screening including frailty measurements (Fried Frailty Index), cognitive screening (Saint Louis University Mental Status score), and functional status evaluation for activities of daily living (Katz ADL score) was conducted.

RESULTS

Sixteen percent (n/N = 25/150) of women were categorized as frail according to the Fried Frailty Index score. After adjusting for education level, 21.3 % of women (n/N = 32/150) screened positive for dementia and 46 (30.7 %) reported functional difficulty or dependence in performing at least one Katz ADL. Sixty-nine women (46.0 %) chose surgical options for treatment of their PFD at the conclusion of their new patient visit with their physician.

CONCLUSIONS

Frailty, cognitive impairment, and functional disability are common in older women seeking treatment for PFD.

Does pelvic organ prolapse reduction affect abdominal leak point pressures?

OBJECTIVE

To determine if pelvic organ prolapse reduction decreases cystometric leak point pressure.

STUDY DESIGN

A retrospective review was performed of women with pelvic organ prolapse points Aa, Ba or C > or = -1 cm that leaked with and without vaginal support (barrier testing) during multichannel urodynamic investigation (N=44). An analysis of the mean and difference between leak point pressure (LPP) (vesicle pressure) with and without prolapse reduction was used to determine significance.

RESULTS

Among 460 possible study subjects, 15% (71/460) leaked only with and 4% (17/460) only without prolapse reduction. Among the 44 women who leaked both with and without prolapse reduction, prolapse reduction was associated with a mean decrease in LPP of 16.1 cm H2O (95% CI 7.4-24.7, p = 0.0005).

CONCLUSION

Reduction of pelvic organ prolapse is associated with a mean decrease in LPP of 16.1 cm H2O.

Duloxetine compared with placebo for treating women with symptoms of overactive bladder

OBJECTIVE

To evaluate duloxetine (a serotonin-noradrenaline reuptake inhibitor) in women with symptoms of overactive bladder (OAB), as it has been shown to increase the bladder capacity in an animal model.

PATIENTS AND METHODS

In all, 306 women (aged 21-84 years) were recruited and randomly assigned to placebo (153) or duloxetine (80-mg/day for 4 weeks increased to 120-mg/day for 8 weeks; 153). Symptoms of OAB were defined as bothersome urinary urgency and/or urge urinary incontinence (UI) for > or =3 months. Participants were also required to have a mean daytime voiding interval (VI) of < or=2 h and urodynamic observations of either detrusor overactivity (DOA) or urgency which limited bladder capacity to <400 mL, both with no stress UI (SUI). The primary efficacy analysis compared the treatment effects on mean change from baseline to endpoint in the mean number of voiding episodes (VE)/24 h. The secondary efficacy analyses compared the treatment effects on the number of UI episodes (IE)/24 h, in the Incontinence Quality of Life questionnaire (I-QOL) score, and on the mean daytime VI. Safety was assessed with vital signs, adverse event reporting, routine laboratory testing, electrocardiogram, and the measurement of postvoid residual urine volumes (PVR).

RESULTS

Patients randomized to duloxetine had significant improvements over those randomized to placebo for decreases in VE and IE, for increases in the daytime VI, and for improvements in I-QOL scores at both doses of duloxetine. Urodynamic studies showed no significant increases in maximum cystometric capacity or in the volume threshold for DOA. The most common treatment-emergent adverse events with duloxetine (nausea, 31%; dry mouth, 16%; dizziness, 14%; constipation, 14%; insomnia, 13%; and fatigue, 11%) were the same as those reported by women with SUI and were significantly more common with duloxetine than placebo. Laboratory assessments, vital signs and electrocardiograms were stable relative to baseline, with no relevant differences detected between groups. There was a significant difference in the change in PVR with duloxetine (<5 mL mean increase) but no patient reported hesitancy or retention.

CONCLUSION

In this trial, duloxetine was better than placebo for treating women with 'wet' and 'dry' symptoms of OAB associated with DOA or a bladder capacity of <400 mL.

The PESSRI study: symptom relief outcomes of a randomized crossover trial of the ring and Gellhorn pessaries

OBJECTIVE

The aim of this randomized crossover trial was to compare symptom relief and change in life impact for women using the ring with support and Gellhorn pessaries.

STUDY DESIGN

Subjects were randomized to use each pessary for 3 months. Outcome data included a visual analog satisfaction score, and quality of life questionnaires. Analysis included student's t-test, Wilcoxan Signed-rank test and logistical regression.

RESULTS

Subjects were primarily white, parous, postmenopausal women with a mean age of 61. The median POPQ stage was III. We enrolled 134 subjects and collected 3-month data on 94 ring and 99 Gellhorn subjects. There were statistically and clinically significant improvements in the majority of the PFDI and many PFIQ scales with both pessaries, but no clinically significant differences between the two pessaries.

CONCLUSIONS

The ring with support and Gellhorn pessaries are effective and equivalent in relieving symptoms of protrusion and voiding dysfunction.

Closure of the subcutaneous dead space and wound disruption after Cesarean delivery

OBJECTIVE

To determine whether suture closure of subcutaneous dead space decreases wound disruption after Cesarean delivery.

METHODS

All patients undergoing Cesarean delivery at the New England Medical Center from September 1995 to June 1997 were eligible. One group (162 patients) was randomly assigned to have the subcutaneous fat layer closed with a running 3-0 plain suture. The other group (165 patients) had this layer left unclosed. Both groups had careful hemostasis of this layer with cautery and copious irrigation. All laboring and ruptured patients received prophylactic antibiotics. The patients were followed for 6 weeks after delivery for wound disruption.

RESULTS

No significant differences were noted between the two groups with respect to demographic, obstetric, or surgical characteristics or loss to follow-up. Excluding those lost to follow-up (27 closed vs. 22 unclosed), there was no difference in wound infection (11 (8.1%) closed vs. 13 (9.1%) unclosed, RR 0.90, 95% CI 0.14, 2.08). There were decreases in risk of skin separation (three (2.2%) vs. six (4.2%), RR 0.53, 95% CI 0.42, 1.93) and seroma or hematoma formation (two (1.5%) vs. seven (4.9%), RR 0.30, 95% CI 0.06, 1.43) that were not statistically significant. Decreases that were not statistically significant were also noted for any wound disruption (14 (10.4%) vs. 21 (14.7%), RR 0.71, 95% CI 0.37, 1.33) and non-infected wound complication (three (2.2%) vs. eight (5.6%), RR 0.40, 95% CI 0.11, 1.47). Increasing gravidity and parity, and Cesarean delivery performed for failure to progress were independent risk factors for any wound complication. Controlling for these factors did not alter the effect of subcutaneous closure.

CONCLUSIONS

Closure of the subcutaneous space does not increase and may protect against wound complications in patients undergoing Cesarean delivery.

Myomectomy fever: testing the dogma

OBJECTIVE

To test the hypothesis that elevated temperature is more common after abdominal myomectomy than after hysterectomy.

DESIGN

Retrospective cohort study.

SETTING

Academic medical center.

PATIENT(S)

One hundred one women who underwent abdominal myomectomy and 160 women who underwent total abdominal hysterectomy for benign disease from 1988-1993.

INTERVENTION(S)

Abdominal myomectomy.

MAIN OUTCOME MEASURE(S)

Temperature of > or = 38.5 degrees C within 48 hours after operation.

RESULT(S)

Although univariate analysis showed that the incidence of elevated temperature was slightly greater among patients who underwent myomectomy (33% versus 26%, relative risk 1.29, 95% confidence interval 0.88-1.90), multivariate logistic regression analysis showed a 3.29 relative risk of elevated temperature (95% confidence interval 1.56-6.96) with myomectomy after controlling for age, parity, estimated blood loss, and treatment by the general gynecology service.

CONCLUSION(S)

After controlling for confounders, myomectomy was found to be an independent predictor for fever in the first 48 hours after operation.

Comparison of ureteral and cervical descents during vaginal hysterectomy for uterine prolapse

OBJECTIVE

The study measured ureteral and cervical locations during vaginal hysterectomy for prolapse and the extent of parametrial ligament shortening possible.

STUDY DESIGN

Cervical and ureteral position were measured in 26 women undergoing uterine prolapse correction. Parametrial clamp tip location was also measured.

RESULTS

The cervix lay between 0 and -14.5 cm (below) the hymen (mean +/- SD -5.35 +/- 3.96 cm) and the ureters lay +5.0 to -4.0 cm (mean +/- SD +1.89 +/- 1.99 cm). Correlation of ureteral with cervical position was 0.69 (P <.01) and correlation with ipsilateral uterosacral ligament clamp positions was 0.80 (P <.01). Regression line slope relating cervical descent and cervix to ureter distance was 0.65, indicating that for every 3 cm of cervical descent there was 2 cm widening of the gap between the cervix and ureters and 1 cm descent of the ureter.

CONCLUSION

For every 3 cm of cervical descent the ureters descend 1 cm, thereby widening the ureterocervical gap and permitting ligament shortening during vaginal hysterectomy.

Normal pelvic floor anatomy

The anatomy of the pelvic floor includes structures responsible for active and passive support of the urethrovesical junction, vagina, and anorectum. Intrinsic and extrinsic properties of the urethrovesical neck and anorectum allow maintenance of urinary and anal continence at rest and with activity. Damage to these structures may lead to loss of support and loss of normal function of the urethra, bladder, and anorectum. Over time, this damage can result in isolated or combined pelvic organ prolapse, urinary incontinence, and anal incontinence.

Pelvic organ prolapse in young women

OBJECTIVE

To determine differences in the characteristics and type of genital prolapse in young women compared with older women.

METHODS

A retrospective analysis was performed, identifying 647 women who underwent surgical repair of various types of genital prolapse for the years 1979-1991. One hundred ninety-one patients met our inclusion criteria, having well-documented genital prolapse to or beyond the hymen. Patients were stratified into two age groups, those over 35 years and those 35 or younger. The patients were compared regarding "complexity" of prolapse (ie, the total number of deficient sites per patient), grade of prolapse, parity and coexistent medical conditions.

RESULTS

During the study period, 27 young women (mean age +/- standard deviation [SD] 30.3 +/- 3.4 years) and 164 older women (mean age +/- SD 60.6 +/- 11.9 years) met our criteria. Young women were more likely than older women to have 1) potential predisposing medical conditions (congenital anomalies or neurologic or connective tissue diseases) (22.2% versus 6.7%, P < .05), 2) lower mean parity (2.8 versus 3.4, P < .05), 3) only one site of prolapse (56% versus 23%, P < .01), and 4) lower grade of prolapse (33% versus 87% grade 3 or higher, P < .001).

CONCLUSION

Young patients undergoing surgery for genital prolapse were more likely to have lower parity and single-site and lower-grade prolapse. A higher than expected prevalence of congenital anomalies, as well as rheumatologic and neurologic diseases in the younger women is intriguing, but further study is necessary before these conditions can be implicated in the genesis of genital prolapse.

The vesico-urethral pressuregram analysis of urethral function under stress

About one-third of older multiparous women are prone to stress urinary incontinence (SUI): unwanted urine loss during activities which suddenly raise intra-abdominal pressure. In this paper we describe and test a method for visualizing and analyzing the function of the urinary continence control system (CCS) under stress. Intravesical and intraurethral pressure changes from the resting state were recorded at proximal, mid-, and distal urethral locations during increasingly severe coughs and cross-plotted on a 'vesico-urethral pressuregram.' The slope (alpha) and intercept (chi zero) resulting from a linear regression analysis of these data were used to develop a continence equation which can be used to predict the equilibrium point pressure (PE): the intravesical pressure at which urine will leak to the intraurethral pressure recording site. We tested the null hypothesis that these parameters would not differ in six young, nulliparous continent women (mean +/- S.D. age: 30 +/- 3.5 yr) and six multiparous SUI women (52.3 +/- 8.0 yr, parity: 1.7 +/- 0.8), or between urethral locations. Significant differences in continence equation parameters were found between groups and in different urethral locations. In the SUI group static factors calculated from the term (1 - alpha) contributed 27% of the mean (S.D.) midurethral PE value, 145 (46) cm H2O, while dynamic factors, estimated from alpha, contributed 73% of this value. Valuable insights for improving the diagnosis and treatment of SUI may be obtained by analyzing the relative contributions of alpha and chi 0 to urethral closure during physical stress.

Magnetic resonance imaging anatomy of the female urethra: a direct histologic comparison

OBJECTIVE

To define the urethral structures visible on magnetic resonance imaging (MRI) relevant to stress urinary incontinence.

METHODS

The urethra and surrounding tissues were harvested from 13 female cadavers (ages 21-81) and fixed in 10% buffered formalin. High-resolution T1- and T2-weighted images were obtained at 1.5 tesla. Mallory trichrome-stained histologic sections were prepared in corresponding planes from the cadaveric specimens. Immunohistologic stains for smooth muscle (actin) and vascular endothelium (CD-34 and factor VIII) were obtained on two specimens. Histology and MRI were compared using side-by-side correlation of projected images and by superimposing projected images. Comparison was also made to a non-cadaveric urethral MRI of a 29-year-old woman and to the MRI of another specimen imaged pre- and post-fixation.

RESULTS

Distinct layers of the cadaveric urethra were seen best on proton density and T2-weighted images. From the center to the periphery, a series of concentric rings were visible: an inner bright ring, the mucosa; a dark ring, the submucosa; an outer bright ring, the smooth muscle of the urethra in a loose connective tissue matrix; and a peripheral dark ring, the striated urogenital sphincter muscle of the urethra in dense connective tissue. No significant alterations were caused by fixation. These cadaveric images matched the non-cadaveric MRI of the 29-year-old woman.

CONCLUSION

The internal urethral anatomy visible on high-resolution MRI can be identified and confirmed histologically, and these findings may form the basis for future anatomic investigation of stress urinary incontinence and other urethral abnormalities.

Relative morbidity of abdominal hysterectomy and myomectomy for management of uterine leiomyomas

OBJECTIVE

To compare the morbidity of total abdominal hysterectomy and abdominal myomectomy in the surgical management of uterine leiomyomas.

METHODS

Hospital records were reviewed for all women who underwent hysterectomy (n = 89) or myomectomy (n = 103) between May 1, 1988, and May 1, 1993, for the preoperative diagnosis of leiomyoma.

RESULTS

There were significant differences between the two groups for average age (hysterectomy 39.2 years, myomectomy 34.4 years; mean difference 4.8, 95% confidence interval [CI] of difference 3.7-5.9), uterine size (hysterectomy 15.2, myomectomy 11.5 weeks; mean difference 3.8, 95% CI of difference 2.0-5.4) and use of a GnRH agonist (hysterectomy 23.6%, myomectomy 55.3%; relative risk [RR] 0.4, 95% CI 0.3-0.6). Myomectomy was associated with decreased estimated blood loss (hysterectomy 796 mL, myomectomy 464 mL; mean difference 331, 95% CI 121-542) and febrile morbidity (risk of temperature 38C or 48 or more hours postoperatively: for hysterectomy 49.4%, for myomectomy 32%; RR 1.5, 95% CI 1.1-2.2). Using multivariate linear regression, estimated blood loss was similar between the groups after controlling for uterine size. There was no difference in blood transfusion rates. There were two ureteral, one bladder, one bowel, and one femoral nerve injury in the hysterectomy group, and there were no intraoperative visceral injuries in the myomectomy group.

CONCLUSION

Myomectomy compares favorably to hysterectomy in the surgical management of leiomyomas, with a possible decreased risk for visceral injury and infection.

Managed care in reconstructive pelvic surgery and urogynecology

While demographic changes in future decades should expand the need for subspecialists in reconstructive pelvic surgery and urogynecology, managed care will probably limit access of patients to specialists in this field. Much of the evaluation and treatment for women with prolapse and incontinence will be provided by primary care providers.

Magnetic resonance imaging of the levator ani with anatomic correlation

OBJECTIVE

To define in women the anatomy of the levator ani muscle visible on magnetic resonance imaging (MRI) so these muscles can be studied in women with prolapse or incontinence.

METHODS

Multiplanar T1- and T2-weighted MRI was obtained of two female pelvic cadaver specimens, ages 25 and 33. One specimen was hemisected, with half sectioned in the axial plane and the other half in the coronal plane. The other specimen was sectioned in the coronal plane. Anatomic cross sections of these specimens were correlated with the cadaver MRI and MRI of living patients. One sagittal and two axial series of anatomic sections not imaged were also used for comparison.

RESULTS

Serial sagittal and axial MRI demonstrates the pubovisceralis ("pubococcygeus") muscle as it originates from the pubic bone, passes alongside the urethra, vagina, and rectum, and then dorsal to the anorectum. Its muscle bulk, attachment to the distal half of the vagina, and insertion between the internal and external anal sphincters can be seen on axial views. The origin of the iliococcygeus muscle at the arcus tendineus levator ani is seen in axial and coronal images. Coronal and sagittal images demonstrate the relative thickness and medial position of the pubovisceralis muscle compared with the thin, diaphragm-like lateral iliococcygeus muscle.

CONCLUSION

Magnetic resonance imaging of the cadaver pelvis demonstrates the detailed anatomy of the levator ani muscle. This is an important precursor to future research of the structure, bulk, and orientation of the levator ani in living women with prolapse.

Pitfalls in the diagnosis of nonconjoined monoamniotic twins

The morbidity and mortality of monoamniotic twins are high. Despite recent advances in imaging, the definitive diagnosis of monoamniotic twins remains elusive. When monoamniotic twins are suspected, the optimal antepartum management is uncertain. A false-positive diagnosis of monoamniotic twins by computed tomographic amniography was investigated. By a Medline search the literature on monoamnionicity from 1966 to January 1994 was reviewed. All reports including diagnostic methods and management of monoamniotic twins were reviewed. All five previous case reports of computed tomographic amniography correctly identified amnionicity in cases in which amnionicity was unclear. Four cases confirmed monoamnionicity and one case excluded monoamnionicity. Four recent series that used ultrasonography revealed a low predictive accuracy (9% to 25%) for the establishment of monoamnionicity when intervening membranes were absent. One recent prospective series revealed a positive predictive value of 80% among five monoamniotic twin pairs with the use of first-trimester ultrasonography. The methods available to diagnose monoamniotic twins are improving. The complications that result from a false-positive diagnosis are discussed and the management and diagnosis of monoamniotic twins are reviewed.
