Graft use in transvaginal pelvic organ prolapse repair: A systematic review

OBJECTIVE: To estimate the anatomic and symptomatic efficacy of graft use in transvaginal prolapse repair and to estimate the rates and describe the spectrum of adverse events associated with graft use. DATA SOURCES: Eligible studies, published between 1950 and November 27, 2007, were retrieved through Medline and bibliography searches. METHODS OF STUDY SELECTION: To assess anatomic and symptomatic efficacy of graft use, we used transvaginal prolapse repair studies that compared graft use with either native tissue repair or repair with a different graft. To estimate rates of adverse events from graft use, all comparative studies and case series with at least 30 participants were included. For spectrum of adverse events, all study designs were included. TABULATION, INTEGRATION AND RESULTS: Eligible studies were extracted onto standardized forms by one reviewer and confirmed by a second reviewer. Comparative studies were classified by vaginal compartment (anterior, posterior, apical, or multiple), graft type (biologic, synthetic-absorbable, synthetic nonabsorbable) and outcome (anatomic, symptomatic). We found 16 comparative studies, including six randomized trials, 37 noncomparative studies with at least 30 women, 11 case series with fewer than 30 women, and 10 case reports of adverse events. One randomized trial and one prospective comparative study evaluating synthetic, nonabsorbable graft use in the anterior compartment reported favorable anatomic and symptomatic outcomes with graft use. Data regarding graft use for posterior and apical compartments or for biologic or synthetic absorbable graft use in the anterior compartment were insufficient to determine efficacy. Rates and spectrum of adverse events associated with graft use included bleeding (0–3%), visceral injury (1–4%), urinary infection (0–19%), graft erosion (0–30%), and fistula (1%). There were insufficient data regarding dyspareunia, sexual, voiding, or defecatory dysfunction. CONCLUSION: Overall, the existing evidence is limited to guide decisions regarding whether to use graft materials in transvaginal prolapse surgery. Adequately powered randomized trials evaluating anatomic and symptomatic efficacy as well as adverse events are needed.

Lactation Intensity and Postpartum Maternal Glucose Tolerance and Insulin Resistance in Women With Recent GDM: The SWIFT cohort

OBJECTIVE To examine the association between breastfeeding intensity in relation to maternal blood glucose and insulin and glucose intolerance based on the postpartum 2-h 75-g oral glucose tolerance test (OGTT) results at 6–9 weeks after a pregnancy with gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS We selected 522 participants enrolled into the Study of Women, Infant Feeding, and Type 2 Diabetes (SWIFT), a prospective observational cohort study of Kaiser Permanente Northern California members diagnosed with GDM using the 3-h 100-g OGTT by the Carpenter and Coustan criteria. Women were classified as normal, prediabetes, or diabetes according to American Diabetes Association criteria based on the postpartum 2-h 75-g OGTT results. RESULTS Compared with exclusive or mostly formula feeding (>17 oz formula per 24 h), exclusive breastfeeding and mostly breastfeeding (≤6 oz formula per 24 h) groups, respectively, had lower adjusted mean (95% CI) group differences in fasting plasma glucose (mg/dL) of −4.3 (−7.4 to −1.3) and −5.0 (−8.5 to −1.4), in fasting insulin (μU/mL) of −6.3 (−10.1 to −2.4) and −7.5 (−11.9 to −3.0), and in 2-h insulin of −21.4 (−41.0 to −1.7) and −36.5 (−59.3 to −13.7) (all P < 0.05). Exclusive or mostly breastfeeding groups had lower prevalence of diabetes or prediabetes (P = 0.02). CONCLUSIONS Higher intensity of lactation was associated with improved fasting glucose and lower insulin levels at 6–9 weeks’ postpartum. Lactation may have favorable effects on glucose metabolism and insulin sensitivity that may reduce diabetes risk after GDM pregnancy.

The Mersilene mesh suburethral sling: A clinical and urodynamic evaluation☆

Abstract OBJECTIVES: Our purpose was to determine the efficacy and safety of the Mersilene (Ethicon, Inc., Somerville, N.J.) mesh sling. STUDY DESIGN: A total of 110 women diagnosed at the University of Massachusetts Medical Center with recurrent genuine stress incontinence, low-pressure urethra, or chronically increased intraabdominal pressure underwent a Mersilene mesh sling procedure. The women were followed up with yearly clinical and 1-year urodynamic evaluations. Sixty-seven patients had both preoperative and postoperative complete urodynamic evaluations. Paired t test was used except where stated. RESULTS: Seventy-nine of 83 patients (95%) who were examined at a mean of 15 months reported complete stress continence. Objective cure rate ( n = 72) by 1-year postoperative stress test was 93%. The pressure transmission ratio increased from 75% to 112% ( p CONCLUSIONS: The suburethral sling with Mersilene mesh is a safe, effective treatment for specific types of genuine stress incontinence on the basis of yearly clinical and 1-year urodynamic follow-up, and it demonstrates a low rejection rate.

Exclusion of elderly women from published randomized trials of stress incontinence surgery

OBJECTIVE: More than 20,000 women, aged 70 years or older, undergo surgery for stress urinary incontinence each year. Our objective was to review the published randomized trials of the surgical treatment of stress urinary incontinence and estimate the proportion of women 70 years or older enrolled in those trials. DATA SOURCES: MEDLINE and Cochrane Databases of Clinical Trials were searched from January 1966 through December 2003 with the terms “urinary incontinence,” “stress incontinence,” “urethropexy,” “needle suspension,” “pubovaginal sling,” “tension-free vaginal tape,” “urethral injection,” “collagen injection,” “anterior colporrhaphy,” and “clinical trial,” “controlled trial,” or “randomized trial” as both subject headings and words contained in article titles. We supplemented this search with manual searches of meta-analyses and review articles from 2000 to 2003. METHODS OF STUDY SELECTION: All studies that included at least one group undergoing an invasive treatment for stress incontinence (including urethral bulking injections) were reviewed. We excluded reports without sufficient data to estimate the number of women aged 70 and older who participated, those published only in abstract form, and those studies in languages other than English, French, German, Italian, or Spanish. Twenty studies met our inclusion criteria. TABULATION, INTEGRATION, AND RESULTS: The number of women aged 70 or older in each study was estimated using the demographic data provided. The median percentage of subjects aged 70 or older was 3.8% (interquartile range 0.37–15%). There was no significant difference in the proportion of subjects 70 years of age or older based on the year of publication. CONCLUSION: Our review of the published literature suggests that elderly women are underrepresented in clinical trials of stress incontinence surgery. Efforts should be made to include more elderly women in clinical trials of stress incontinence surgery.

Anatomic outcomes of vaginal mesh procedure (Prolift) compared with uterosacral ligament suspension and abdominal sacrocolpopexy for pelvic organ prolapse: a Fellows' Pelvic Research Network study

OBJECTIVE The objective of the study was to compare apical support anatomic outcomes following vaginal mesh procedure (VMP) (Prolift) to uterosacral ligament suspension (USLS) and abdominal sacrocolpopexy (ASC). STUDY DESIGN This multicenter, retrospective chart review compared apical anatomic success (stage 0 or 1 based on point C or D of the Pelvic Organ Prolapse Quantification), level of vaginal apex (point C or D) 3-6 months after prolapse repair at 10 US centers between 2004 and 2007. RESULTS VMP, USLS, and ASC were performed for 206, 231, and 305 subjects respectively. There was no difference in apical success after VMP (98.8%) compared with USLS (99.1%) or ASC (99.3%) (both P = 1.00) 3-6 months after surgery. The average elevation of the vaginal apex was lower after VMP (-6.9 cm) than USLS (-8.05 cm) and ASC (-8.5 cm) (both P < .001) CONCLUSION Patients undergoing VMP have similar apical success compared with USLS and ASC despite lower vaginal apex 3-6 month after surgery.

Paper versus web-based administration of the Pelvic Floor Distress Inventory 20 and Pelvic Floor Impact Questionnaire 7

Web-based questionnaires are increasingly employed for clinical research. To investigate whether web-based and paper versions of the Pelvic Floor Distress Inventory 20 (PFDI-20) and Pelvic Floor Impact Questionnaire 7 (PFIQ-7) yield similar results, we compared results obtained with these two modes of administration. Women with pelvic floor disorders completed both versions of these questionnaires. Scores between modes of administration were compared using the paired t test and the intraclass correlation coefficient (ICC). Among the 52 participants, there were no significant differences in scores or scale scores between the web-based and paper questionnaires. The ICC was 0.91 for the PFDI-20 score and 0.81 for the PFIQ-7 score (p < 0.001 for each). The web-based format was preferred by 22 participants (53%), ten (24%) preferred the paper format, and nine (21%) had no preference. The acceptability and score equivalence recommend these web-based questionnaires as an alternative to paper questionnaires for clinical research.

Influence of Breastfeeding During the Postpartum Oral Glucose Tolerance Test on Plasma Glucose and Insulin

OBJECTIVE: To examine the effect of breastfeeding during the postpartum oral glucose tolerance test (OGTT) on maternal blood glucose and insulin among women with recent gestational diabetes mellitus. METHODS: Participants were enrolled in the Study of Women, Infant Feeding, and Type 2 Diabetes, a prospective observational cohort study of 1,035 Kaiser Permanente Northern California members who had been diagnosed with GDM and subsequently underwent a 2-hour 75-g OGTT at 6–9 weeks postpartum for the study enrollment examinations from 2008 to 2011. For this analysis, we selected 835 study participants who reported any intensity of lactation and were observed either breastfeeding their infants (ie, putting the infant to the breast) or not breastfeeding during the OGTT. RESULTS: Of 835 lactating women, 205 (25%) breastfed their infants during the 2-hour 75-g OGTT at 6–9 weeks postpartum. Mean (standard deviation) duration of breastfeeding during the OGTT was 15.3 (8.1) minutes. Compared with not having breastfed during the OGTT, having breastfed during the test was associated with lower adjusted mean (95% confidence interval) 2-hour glucose (mg/dL) by −6.2 (−11.5 to −1.0; P=.02), 2-hour insulin (microunits/mL) by −15.1 (−26.8 to −3.5; P=.01), and natural log 2-hour insulin by −0.15 (−0.25 to −0.06; P<.01), and with higher insulin sensitivity index0,120 by 0.08 (0.02–0.15; P=.02), but no differences in plasma fasting glucose or insulin concentrations. CONCLUSION: Among postpartum women with recent gestational diabetes mellitus, breastfeeding an infant during the 2-hour 75-g OGTT may modestly lower plasma 2-hour glucose (5% lower on average) as well as insulin concentrations in response to ingestion of glucose.

Ovarian Burkitt lymphoma: pelvic pain in a woman with AIDS.

Background Non-Hodgkin lymphomas, a common, AIDS-defining manifestation of human immunodeficiency virus (HIV), are aggressive, advanced at diagnosis, and tend to involve extranodal sites. Burkitt lymphoma comprises approximately 20% of AIDS-related non-Hodgkin lymphomas. Sites frequently affected by the disease include the central nervous system, bone marrow, gastrointestinal tract, and mucocutaneous tissue. Gonadal involvement is less common; reports of testicular lymphomas in adult males with AIDS have been sporadic. Ovarian involvement in AIDS-related lymphoma is exceedingly rare and usually involves pediatric patients. Case We report an unusual case in which disseminated Burkitt lymphoma presented as pelvic pain in a 32-year-old woman with AIDS. At laparoscopy, the ovaries were unremarkable in appearance but at the upper limits of normal size. However, extreme friability of the left ovary led to hemorrhage and oophorectomy. Pathologic evaluation of the ovary resulted in the diagnosis of Burkitt lymphoma. Conclusion With improved survival because of antiretroviral therapy, the incidence of AIDS-related lymphomas is expected to rise. Lymphoma should be considered in the differential diagnosis of women with AIDS with perplexing abdominal or pelvic symptoms.

Society of gynecologic surgeons' survey: mesh use in vaginal prolapse surgery.

Objective: To evaluate the practice patterns of the Society of Gynecologic Surgeons (SGS) members and guests regarding the use of synthetic mesh in vaginal prolapse repair. Methods: A 26-item questionnaire regarding synthetic mesh use in vaginal prolapse repair was placed on the desks of those SGS attendees present at the fourth scientific session of the 2008 annual scientific meeting. Voluntary participation was requested and the survey questionnaires were retrieved at the sessions conclusion. Descriptive statistics and cross-tabulation using &khgr;2 tests were performed with SPSS. Results: One hundred twenty-eight of the 180 scientific session attendees completed the surveys. Sixty-nine percent (88/128) of the respondents identified themselves as urogynecologists and 45% (83/128) were male. Forty-five percent (58/128) were SGS members. Sixty-six percent (84/128) described their practice setting as academic, 28% (36/128) as community-based, and 6% (8/128) as other. The majority of the urogynecologists, 65% (64/88), used mesh at the time of survey completion versus 40% (8/18) of the obstetrician/gynecologists (P < 0.001). Fifty-nine percent (74/125) respondents were currently using mesh and 11% (14/125) reported using mesh at one time. Fifty-six percent (48/86) used mesh in both primary and recurrent repairs. For anterior repair, 97% (82/86) used mesh; of these, 31% (26/86) used only mesh kits, 33% (28/86) used only free mesh and 33% (28/86) reported using both. For posterior repair, 70% (62/88) used mesh; of these 18% (16/88) used only mesh kits, 26% (23/88) used only free mesh and 26% (23/88) used both. For anterior repair, 84% (71/85) dissected full-thickness and 43% (35/85) plicated connective tissue prior to inserting the mesh. The respondents had excised mesh for indications including: persistent drainage (59%), persistent pain (21%), hispareunia (21%), dyspareunia (16%), and asymptomatic exposure (11%). Fifty percent (44/88) initially managed mesh erosion with estrogen cream whereas 29% (26/88) started with mesh excision. Conclusions: This survey suggests that the majority of urogynecologists attending the 34th SGS annual scientific meeting have used vaginal mesh for prolapse repair, and they more commonly used it in the anterior as compared to the posterior compartment. This has occurred in the absence of prospective, controlled, high-quality studies supporting its efficacy and safety. Research is clearly needed in this area.
