Fertility after expanded polytetrafluoroethylene use after endometrioma cystectomy: a pilot study.

Introduction: Pregnancy rates after the placement of expanded polytetrafluoroethylene (ePTFE, trade name Gore-Tex®) for adhesion prevention following cystectomy of endometriomas ≥3 cm and excision of endometriosis were analyzed in this pilot study. Methods: A prospective cohort study was performed at a single tertiary care center. 56 women qualified for the study and underwent surgery. Expanded polytetrafluoroethylene placement around affected ovaries was self-selected. Inclusion criteria for analysis were pathology-confirmed endometrioma ≥3 cm, no hysterectomy at time of surgery, ≥1 year of postoperative survey completion, and absence of strategies to avoid pregnancy. 18 women in the ePTFE group and 11 women in the control group met inclusion criteria for analysis. 16 of the 18 women in the ePTFE group and 7 of the 11 women in the control group were affected by infertility. Absolute pregnancy rates and cumulative 4-year pregnancy rates, which are based on survival analysis using lifetables and adjust for varying follow-up times, were calculated for all women as well as for women with infertility only. Results: High cumulative 4-year pregnancy rates were observed for women with expanded polytetrafluoroethylene compared to women without (85% vs. 65%, p = 0.69). High cumulative 4-year pregnancy rates for women with infertility prior to surgery were observed for women with expanded polytetrafluoroethylene compared to women without (83% vs. 33%, p = 0.89). Discussion: There are consistent trends, although not statistically significant, seen in pregnancy rates for women with ePTFE compared to women without, particularly in those with a history of infertility prior to ePTFE use. This is the first study examining how adhesion prevention strategy targeting the adnexa during surgery for endometriosis affects pregnancy rates. The trend towards increased pregnancy rates with expanded polytetrafluoroethylene use, particularly in patients with a history of infertility, is promising and warrants further study with larger groups.

Residency match interview scheduling: quantifying the applicant experience.

BACKGROUND: The process of offering and scheduling residency interviews varies widely among programmes. Applicants report distress and have advocated for reform. However, there is a paucity of quantitative data to characterise applicant concerns. OBJECTIVE: We quantified the interview scheduling experience for US allopathic medical students in the 2020 main residency match. METHODS: An anonymous, 13 question survey was sent to student representatives from each Association of American Medical Colleges member institution. Recipients were asked to forward the survey to their entire fourth-year class. RESULTS: Of 4314 applicants to whom the survey was sent, 786 (18.2%) responded. Overall, 20.4% reported missing the opportunity to interview at a programme because they did not have adequate time to respond to an invitation; applicants into surgical specialties were significantly more likely than their non-surgical peers to report this experience (26.4% vs 18.4%, p<0.05). Most (57.4%) respondents scheduled an interview knowing they would likely cancel it in the future. The most commonly cited reason for this behaviour was concern that applicants would not receive invitations from other programmes (85.6%). A majority (56.4%) of respondents did not believe the match interview process functions based on equity and merit. CONCLUSIONS: About one in five respondents missed the opportunity to interview at a programme because they did not respond to an invitation in time. Most respondents scheduled interviews knowing that they were likely to cancel them in the future. Standardisation of the interview invitation timeline would address these concerns.

Cystoscopic findings in women with minimal and maximal lower urinary tract symptoms.

BACKGROUND: Glomerulations are not specific for interstitial cystitis/bladder pain syndrome (IC/BPS). Controversy exists about whether cystoscopic findings differ between patients with and without lower urinary tract symptoms. We sought to compare the prevalence of cystoscopic findings in women with "no or minimal" urinary symptoms to those with a "high" symptom burden. METHODS: This is a secondary analysis of a prospective cohort study performed at a University Educational Facility. Participants in this study were part of a larger prospective study, in which female patients scheduled to undergo routine gynecologic procedures were all consented for cystoscopy with hydrodistension (CWHD). We defined the "minimally symptomatic group" as those with ≤1 on each of the O'Leary/Sant Interstitial Cystitis Symptom Index (ICSI) subscores and without history of IC/BPS. The "highly symptomatic" cohort of women had composite ICSI score ≥12 and a Burning/Pain subscore of 4 or 5. All were non-smokers. RESULTS: A total of 84 women underwent CWHD, with 33 having minimal symptoms and 51 being highly symptomatic. The two groups were not statistically different when assessing for 'any glomerulations' compared to 'no glomerulations.' However, minimally symptomatic women had an eight-fold lower prevalence of significant glomerulations than highly symptomatic women (3.0% minimally symptomatic vs. 23.5% highly symptomatic, P<0.05.). CONCLUSIONS: Extensive glomerulations (≥10 in 3 or 4 quadrants) are rare in women with minimal urinary symptoms. These findings contrast with prior limited prospective data which quoted similar incidence of glomerulations in IC/BPS patients and asymptomatic patients. This study highlights the importance of evaluating objective evidence on CWHD and merits further investigation as part of the ongoing conversation regarding the definition of bladder health and pathology.

Closing the knowledge gap in pelvic neuroanatomy: assessment of a cadaveric training program.

BACKGROUND: The objective of this study is to characterize participants in a laparoscopic cadaveric neuroanatomy course and assess knowledge of pelvic neuroanatomy before and after this course. METHODS: This is a survey-based cohort study with a setting in a university educational facility. The participants are surgeons in a multiday laparoscopic cadaveric pelvic neuroanatomy course. Participants completed a precourse survey, including demographics and comfort with laparoscopic surgery. They then completed an identical precourse and postcourse anatomic knowledge test. Main outcomes are scores on the anatomic knowledge test precourse and postcourse. RESULTS: 44 respondents were included: 25 completed fellowship, 15 completed residency, 2 were residents, and 2 were fellows. Participants were on average 11.09 years post training, with an average of 8.67 years from training if they completed fellowship and 18.62 years if they completed residency only. 22 of 42 respondents strongly agreed or agreed they are comfortable performing complex laparoscopic hysterectomies. The average precourse score was 32.18/50 points and the mean difference score (MDS, defined as mean of Postcourse scores minus Precourse scores) was 9.80, showing significant improvement (p <  0.001). Precourse and MDS scores were not significantly different when comparing country of practice, level of training, or time since training. CONCLUSION: Baseline knowledge of pelvic neuroanatomy was similar among groups when comparing fellowship status, place of training, or time since training. There was significant improvement in knowledge after training in this dissection method. This course garnered interest from surgeons with broad training backgrounds.

Maternity homes and social support: A cross-sectional survey stratifying outcomes.

Poor social support is associated with adverse obstetric outcomes. Maternity group homes (MGHs), residential programs for pregnant women, have been found to improve social support in small studies. The present study aimed to verify these previous studies, discover whether there is a group of women whom MGHs most benefit, identify what services offer that benefit, and identify how to predict who will most benefit from MGH admission. Forty-three US MGHs from 14 states were surveyed from August 2015 to February 2017. The primary outcome was self-reported social support before and during MGH admission. The secondary outcome was the perception that MGH admission would help current and future relationships. Among 95 respondents, 54% perceived better in-MGH support compared to pre-MGH support. Women with poor pre-MGH support reported improvement; the converse was true of high pre-MGH support (P < 0.001). A total of 77% to 82% of participants anticipated that MGH admission would help current and future relationships, including 91% to 92% of women with stable or increased in-MGH support (P = 0.07 current, P < 0.01 future). Participants with increased in-MGH support reported more services as helpful (P < 0.05). In summary, MGHs are associated with improved support and relationships for most residents. The support score may identify which women may benefit most from MGH admission.

Concordance Rates Between Resident-Performed Ultrasound Measurements and Certified Sonographer Measurements.

OBJECTIVES: To evaluate the accuracy of ultrasound (US) estimated fetal weight (EFW) measurement compared with neonatal birth weight when performed by residents versus certified sonographers. The hypothesis tested was that residents and certified sonographers would not differ significantly in EFW or in EFW compared with neonatal birth weight. METHODS: A retrospective chart review of 142 inpatients from July 2010 to May 2011 was conducted. Ultrasound examinations were performed by a resident physician and a certified sonographer within 7 days after the resident. Standard US measurements obtained were head circumference, biparietal diameter, abdominal circumference, femur length, estimated gestational age, and EFW. Gestational age ranged from 20 to 39 weeks. The time from US to delivery, residency year, and birth weight were collected. Measurements were compared by paired t tests, the Wilcoxon signed rank test, and repeated-measures analysis of variance. RESULTS: The US EFW by residents and sonographers showed excellent concordance with each other regardless of the neonatal birth weight. The resident and sonographer EFW each showed excellent concordance with the neonatal birth weight, and this concordance did not differ significantly between residents and sonographers for neonates weighing less than 1000 g (P = .61) and neonates weighing greater than or equal to 1000 to less than 2000 g (P = .93). The resident EFW (P < .05) and sonographer EFW (P < .01), however, were less than the neonatal birth weight for larger neonates (≥2000 g), but the degree of underestimation was not significantly different between residents and sonographers (P = .51). CONCLUSIONS: Accurate EFW is critical for prenatal management. These data support the value of a dedicated month of US training in residency programs.

Metoclopramide and Diphenhydramine: A Randomized Controlled Trial of a Treatment for Headache in Pregnancy when Acetaminophen Alone Is Ineffective (MAD Headache Study).

OBJECTIVE: We investigated whether metoclopramide administered with diphenhydramine (MAD) relieves headache in pregnant women when acetaminophen alone is ineffective, using codeine for comparison. STUDY DESIGN: Normotensive pregnant women in the second or third trimester were randomized to MAD intravenously (10 mg and 25 mg, respectively) or codeine orally (30 mg) for headache after 650 to 1,000 mg of acetaminophen failed to relieve their headaches. Headache severity (pain score 0-10) was noted at intervals over 24 hours. The primary outcome was reduction in pain score 6 hours after medication administration. A sample size calculation of 35 patients per group was based on estimated reduction in headache pain score by at least two points, with an α of 0.05 and a power of 80%. RESULTS: No difference was seen in the primary outcome. MAD pain scores were lower at 30 minutes (3 ± 2.8 versus 5.8 ± 2.3, p < 0.001), 1 hour (2.2 ± 2.3 vs. 4.1 ± 3; p < 0.01), and 12 hours (1.3 ± 2.5 vs. 2.7 ± 3; p < 0.05), but not at 6 hours. Time to perceived headache relief was shorter for MAD than for codeine (20.2 ± 13.4 vs. 62.4 ± 62.2 minutes; p < 0.001). More patients in the MAD group reported full headache relief within 24 hours (76.5 vs. 37.5%; p < 0.01). CONCLUSION: MAD effectively relieves headaches in pregnant women when acetaminophen fails.

Endometriosis in Hydatid Cysts of Morgagni: A Retrospective Cohort Study of Another Atypical Manifestation of Endometriosis.

STUDY OBJECTIVE: To report on the presence and rate of endometriosis in hydatid cysts of Morgagni found at the time of excision surgery for endometriosis and to describe any association of endometriosis in hydatid cysts of Morgagni with preoperative or operative factors. DESIGN: A retrospective cohort study (Canadian Task Force Classification II-2). SETTING: The Center for Endometriosis at Saint Louis University, a tertiary referral center for endometriosis. PATIENTS: Women who underwent optimal excision surgery for suspected endometriosis because of chronic pelvic pain and/or infertility and who also had hydatid cysts of Morgagni removed at the time of surgery when found. INTERVENTIONS: Preoperative and operative data were collected prospectively. MAIN OUTCOME MEASURES: The rate of endometriosis in hydatid cysts of Morgagni. Secondary measures included are the rate of hydatid cysts of Morgagni in patients with pelvic pain or infertility with and without endometriosis in the cysts. RESULTS: The overall prevalence of endometriosis in hydatid cysts of Morgagni was 11.3%. Patients with pelvic pain had a higher rate (although not statistically significant) of hydatid cysts of Morgagni compared with those without pain (21.1% vs 12.5 %, p = .54). Patients with infertility had a higher rate of hydatid cysts of Morgagni compared with those without infertility (38.1% vs 16.7%, p < .001), and there was a higher rate of endometriosis in the hydatid cysts of Morgagni in patients with infertility compared with those without (11.1% vs 0.0%, p < .001). CONCLUSIONS: This study is the first known report of endometriosis found within hydatid cysts of Morgagni. With a rate of 11.3% of cysts of Morgagni having endometriosis within them, this study supports a practice of removing hydatid cysts of Morgagni at the time of surgery in order to achieve optimal excision of endometriosis. The rates of hydatid cysts of Morgagni and of endometriosis found within hydatid cysts of Morgagni were higher in patients with infertility. Further studies are needed to evaluate whether excising cysts of Morgagni affects clinical outcomes.

Gestational Weight Gain and Maternal and Neonatal Outcomes in Underweight Pregnant Women: A Population-Based Historical Cohort Study.

Objective Limited data are available that estimate the effect of gestational weight gain on maternal and neonatal outcomes in underweight women according to revised 2009 Institute of Medicine (IOM) guidelines. Methods A population-based historical cohort study of 21,674 underweight women in Missouri delivering liveborn, singleton, term infants in 2002-2008 was conducted. Adjusted odds ratios were calculated for gestational weight gain categories with multiple logistic regression, using the 2009 IOM recommended 28-40 pounds as the reference group. Results Women gaining >40 pounds compared to women gaining 28-40 pounds had significantly higher odds for preeclampsia (aOR 1.94, 95% CI 1.56-2.42, p < 0.001), cesarean delivery (aOR 1.40, 95% CI 1.28-1.53, p < 0.001), large-for-gestational-age (LGA) infant (aOR 2.32, 95% CI 2.00-2.70, p < 0.001), and 1 min APGAR score <4 (aOR 1.36, 95% CI 1.01-1.83, p < 0.05) and significantly lower odds for small-for-gestational-age (SGA) infant (aOR 0.53, 95% CI 0.48-0.59, p < 0.001). Women gaining <28 pounds compared to women gaining 28-40 pounds had significantly higher odds for SGA infant (aOR 1.85, 95% CI 1.69-2.03, p < 0.001) and significantly lower odds for preeclampsia (aOR 0.72, 95% CI 0.53-0.96, p < 0.05) and LGA infant (aOR 0.50, 95% CI 0.39-0.63, p < 0.001). Conclusion Women gaining more than the IOM recommendation were at higher risk for many adverse outcomes, but at lower risk for SGA infants. Women gaining less than the IOM recommendation were at higher risk for SGA infants but were protective for preeclampsia and LGA infants. Prospective studies of other short- and long-term maternal/infant outcomes are needed to evaluate the efficacy of the IOM guideline.

Tension compared to no tension on a Foley transcervical catheter for cervical ripening: a randomized controlled trial.

BACKGROUND: Cervical ripening of an unfavorable cervix can be achieved by placement of a transcervical catheter. Advantages of this method include both lower cost and lower risk of tachysystole than other methods. Despite widespread use with varying degrees of applied tension, an unanswered question is whether there is an advantage to placing the transcervical catheter to tension compared with placement without tension. OBJECTIVE: The purpose of this study was to determine whether tension placed on a transcervical balloon catheter that is inserted for cervical ripening results in a faster time to delivery. STUDY DESIGN: This was a prospective, randomized controlled trial; 140 women who underwent cervical ripening (Bishop score, ≤6) were assigned randomly to a balloon catheter with applied tension vs no tension. Tension was created when the catheter was taped to the patient's thigh and tension was reapplied in 30-minute increments. There were 67 patients in the tension group and 73 patients in the no tension group. Low-dose oxytocin (maximum, 6 mU/min) was administered after catheter placement. The primary outcome was time from catheter insertion to delivery. A secondary outcome was time from insertion to catheter expulsion. The Kolmogorov-Smirnov test was used to determine whether the data were distributed normally. Survival curves that used lifetables were constructed from time of catheter insertion to delivery and from time of catheter insertion to catheter expulsion and were compared with the use of the Wilcoxon (Gehan) Breslow statistic. A probability value of <.05 was set to denote statistical significance. RESULTS: Baseline characteristics were similar between groups. The median time from catheter insertion to delivery was not significantly different between the tension group and the no tension group (16.2 vs 16.9 hours; P=.814). The median time from catheter insertion to expulsion, however, was significantly less in the tension group vs the no tension group (2.6 vs 4.6 hours; P<.001), respectively. Vaginal delivery within 24 hours was not significantly different between the tension and no tension groups (41/52 [79%] vs 37/52 [71%]; P=.365) nor were there significant differences in cesarean delivery rates between the tension and no tension groups (17/67 [25%] vs 27/73 [37%]; P=.139). CONCLUSION: Application of tension did not result in faster delivery times but did result in faster times to catheter expulsion.

Standard External Doppler Fetal Heart Tracings versus External Fetal Electrocardiogram in Very Preterm Gestation: A Pilot Study.

Introduction Very preterm babies can be difficult to monitor using standard external Doppler fetal heart tracings (eFHR). External fetal electrocardiogram (fECG) is a potential alternative. Methods This was a prospective observational pilot study of hospitalized patients at 24 to 28 weeks' gestation. A total of 30 women were traced for up to 2 hours using eFHR followed by up to 2 hours using fECG. The percentage of time the fetal heart rate was traced during the 2-hour window for each modality was calculated. Differences of ≥ 60, ≥ 80, and ≥ 90% total time traced were compared between modalities using McNemar's test. Differences were also assessed for each method between nonobese (body mass index [BMI] < 30 kg/m2) and obese (BMI ≥ 30 kg/m2) women using chi-square and Fisher's exact tests. Results Superior performance was found with eFHR at ≥ 60% (93.3 vs. 46.7%, p < 0.001), ≥ 80% (80.0 vs. 30.0%, p < 0.001), and ≥ 90% (60.0 vs. 23.3%, p < 0.01) total time traced. There was a statistically significant finding favoring nonobese women at ≥ 80% total time traced using fECG (7.1 vs. 50.0%, p = 0.017). Conclusion With current technology fECG performance in very preterm gestation was worse than conventional eFHR, although fECG may have a role in nonobese patients.

Effect of Vestibulectomy for Intractable Vulvodynia.

STUDY OBJECTIVE: To assess the effectiveness of vestibulectomy in treating vulvodynia for patients with inadequate response to vulvar care guidelines and medical management. DESIGN: Retrospective case series (Canadian Task Force classification II-2). PATIENTS: All patients who underwent a vestibulectomy from 2004 to 2013 for vulvodynia. INTERVENTIONS: All patients in this study underwent a vestibulectomy. MEASUREMENTS AND MAIN RESULTS: In this study we analyzed 31 patients' overall reported pain scores and Q-tip test scores before and after vestibulectomy. The efficacy of vestibulectomy on reduction of pain was then analyzed after surgical management. There was no significant difference in pain scores from initial visit compared with the last visit before vestibulectomy after vulvar care guidelines and medical management were initiated (p = .48-.94). However, mean subjective pain scores before and after vestibulectomy decreased by 67% (p < .001). Q-tip testing showed reductions of pain by 63% (p < .001) and 73% (p < .001) at the right and left Bartholin gland areas, respectively. There was approximately a 60% decrease of pain scored around the bilateral periurethral areas (p < .05). CONCLUSIONS: Vestibulectomy is an effective treatment for vulvodynia. For those with intractable pain, vestibulectomy is an appropriate next step after unsuccessful medical treatment. The surgery leads to a significant decrease in patients' pain scores, nearly eliminating it in most cases.

Deep Retraction Pockets, Endometriosis, and Quality of Life.

OBJECTIVE: The purpose of this study was to examine if deep retraction pockets (DRPs) in the posterior cul-de-sac and uterosacral ligaments could be a manifestation of endometriosis and if excision of these pockets improves pain symptoms and quality of life. STUDY DESIGN: Prospective cohort study Canadian Task Force Classification, II-3. MATERIALS AND METHODS: Preoperative data, operative data, and follow-up data were collected prospectively at the Center for Endometriosis at Saint Louis University, a referral center for the surgical management of endometriosis. RESULTS: The 107 consecutive patients who presented with preoperative deep dyspareunia were included in the study, and the median postoperative follow-up was 13 months. Endometriosis was confirmed histologically in any location excised in 88/107 (82.2%) of the women, and 31 DRPs were excised from 25 women with DRPs in the posterior cul-de-sac or uterosacral ligaments, of which 15/31 (48.4%) had endometriosis. Of the 10 DRPs without visible surface lesions, 3 (30.0%) had endometriosis on histology. Pain symptoms and quality of life significantly improved after excision surgery, whether or not DRPs were present. Women who had endometriosis in their DRP also had significant improvement in deep dyspareunia and chronic pelvic pain and quality of life. Results did not differ when patients who took postoperative hormonal suppression were removed from the analyses. CONCLUSION: Patients had significantly improved pain symptoms and quality of life after excision surgery, whether or not DRPs were present. This study demonstrated that a DRP may be a manifestation of endometriosis (even with a clear surface of the pocket), so that DRPs should be excised to achieve optimal excision of endometriosis.

Characteristics of Recurrent Large-for-Gestational-Age Infants in Obese Women.

Objective The objective of this study was to identify characteristics associated with recurrent large-for-gestational-age (LGA) infants in obese women and to explore the relationship between interpregnancy weight change and gestational weight gain (GWG) on risk of recurrence. Study Design We conducted a population-based historical cohort study of 1,190 obese women in Missouri who delivered LGA infants in their first pregnancy with two consecutive pregnancies resulting in singleton live births during 1998 to 2005. Adjusted odds ratios (aORs) for recurrent LGA infants were calculated with multiple logistic regression. Population-attributable risk assessed the relative importance of specific characteristics. Results A second LGA infant was delivered by 501 women (42%). Recurrence of LGA infants was associated with GWG (aOR, 1.03 [per pound]; 95% confidence interval [CI], 1.02-1.04), maternal age (aOR, 1.05 [per year]; 95% CI, 1.02-1.08), birth weight of the first LGA infant (aOR, 1.001 [per gram]; 95% CI, 1.000-1.001), being married (aOR, 1.71; 95% CI, 1.02-2.49), diabetes (aOR, 1.79; 95% CI, 1.24-2.59), and pre-pregnancy body mass index (BMI) (aOR, 1.04 [per unit BMI]; 95% CI, 1.02-1.06). Excessive GWG contributed the most to LGA infant recurrence (13%). Interpregnancy weight change was not significantly associated with LGA infant recurrence. Conclusion Lower pre-pregnancy BMI and reduced GWG may mitigate the risk of recurrent LGA infants in obese women.

Incidence of successful voiding and predictors of early voiding dysfunction after retropubic sling.

INTRODUCTION AND HYPOTHESIS: There is a paucity of literature on resumption of normal voiding predictors after synthetic retropubic sling insertion and lack of a standardized method of determination. Our goals were to determine the incidence of a successful voiding trial; whether clinical, operative, or urodynamic variables predict discharge with a catheter; and incidence of later retention in those who were initially successful. METHODS: We performed an internal-review-board (IRB)-approved retrospective chart review of 229 consecutive patients who underwent retropubic sling (TVT, Boston Scientific, Natick, MA, USA)) from 2001 to 2010. Exclusions were concomitant surgery or cystotomy at the time of retropubic sling insertion. All participants underwent a voiding trial in recovery consisting of 300 cc sterile-water retrograde fill and were discharged home without a catheter after single void of at least 200 cc following catheter removal. RESULTS: Of 170 patients, 136 (80 %) passed the voiding trial the same day, with 165 (97 %) passing within 1 day. Factors associated with delayed voiding were age ≥65 years (p < 0.05), presence of Valsalva voiding (p < 0.01), lower body mass index (BMI) (p < 0.05), and higher gravidity (p < 0.05) and parity (p < 0.01). Age ≥65 years [adjusted odds ratio (aOR) 3.72, 95 % confidence interval (CI) 1.40-9.90, p < 0.01] and Valsalva voiding (aOR 3.89, 95 % CI 1.56-9.69, p < 0.01) remained significant independent predictors in multivariate analysis. CONCLUSIONS: The majority of patients with retropubic sling can be safely discharged home the same day without a catheter after retrograde fill. Women >65 years or Valsalva voiders had nearly four times the odds of being discharged with a catheter. Most patients resume normal voiding within 24 h after retropubic sling insertion, but >65 years and Valsalva voiding are risk factors for voiding inability at discharge.

A barrier retractor to reduce surgical site infections and wound disruptions in obese patients undergoing cesarean delivery: a randomized controlled trial.

BACKGROUND: Surgical site infections (SSIs) are an important cause of morbidity following cesarean delivery, particularly in obese patients. Methods to reduce SSIs after cesarean delivery would have an important impact in obese obstetric patients. OBJECTIVE: The purpose of this study was to determine whether the Alexis O cesarean delivery retractor, a barrier self-retaining retractor, reduces SSIs and wound disruptions in obese patients undergoing cesarean delivery. STUDY DESIGN: This was a randomized controlled trial of obese women (body mass index ≥ 30 kg/m(2)) undergoing nonemergent cesarean delivery. Patients were randomized to the treatment group (using the Alexis O cesarean delivery retractor) or to the control group (using conventional handheld retractors). The primary outcome was SSI or wound disruption during the 30 day postoperative period. Secondary outcomes included operative time, estimated blood loss, change in hemoglobin, antiemetic use, length of postoperative hospital stay, hospital readmission, and other postoperative complications. RESULTS: A total of 301 patients were enrolled in the study. One hundred forty-four patients were randomized to the treatment group and 157 to the control group. Baseline characteristics and indications for cesarean delivery were similar between the 2 groups. Median body mass index was 40.1 kg/m(2). There were no significant differences between the treatment and the control group in the primary outcome of SSI or wound disruption rates at the 30 day assessment (20.6% vs 17.6%, P = .62), during the postoperative inpatient hospitalization or at the 1-2 week postoperative visit. There were also no differences in the primary outcome when adjusting for obesity class or thickness of the subcuticular layer. Patients in the treatment group had lower rates of uterine exteriorization (54.3% vs 87.3%, P < .001), but there were no differences in all other outcomes. CONCLUSION: Use of the Alexis retractor in cesarean delivery deliveries did not decrease SSI or wound disruption rates in an obese population. Its use as a retractor should be left to the discretion of the surgeon and clinical circumstances.

Single-Use Energy Sources and Operating Room Time for Laparoscopic Hysterectomy: A Randomized Controlled Trial.

STUDY OBJECTIVES: To compare the intraoperative direct costs of a single-use energy device with reusable energy devices during laparoscopic hysterectomy. DESIGN: A randomized controlled trial (Canadian Task Force Classification I). SETTING: An academic hospital. PATIENTS: Forty-six women who underwent laparoscopic hysterectomy from March 2013 to September 2013. INTERVENTIONS: Each patient served as her own control. One side of the uterine attachments was desiccated and transected with the single-use device (Ligasure 5-mm Blunt Tip LF1537 with the Force Triad generator). The other side was desiccated and transected with reusable bipolar forceps (RoBi 5 mm), and transected with monopolar scissors using the same Covidien Force Triad generator. The instrument approach used was randomized to the attending physician who was always on the patient's left side. Resident physicians always operated on the patient's right side and used the converse instruments of the attending physician. MEASUREMENTS AND MAIN RESULTS: Start time was recorded at the utero-ovarian pedicle and end time was recorded after transection of the uterine artery on the same side. Costs included the single-use device; amortized costs of the generator, reusable instruments, and cords; cleaning and packaging of reusable instruments; and disposal of the single-use device. Operating room time was $94.14/min. We estimated that our single use-device cost $630.14 and had a total time savings of 6.7 min per case, or 3.35 min per side, which could justify the expense of the device. The single-use energy device had significant median time savings (-4.7 min per side, p < .001) and total intraoperative direct cost savings ($254.16 per case). CONCLUSIONS: A single-use energy device that both desiccates and cuts significantly reduced operating room time to justify its own cost, and it also reduced total intraoperative direct costs during laparoscopic hysterectomy in our institution. Operating room cost per minute varies between institutions and must be considered before generalizing our results.

Women's Perceptions Regarding Obesity and Comorbidities and Provider Interaction.

OBJECTIVE: To assess women's perceptions of current body mass index (BMI) category, evaluate their knowledge of medical and surgical conditions associated with obesity, and assess their previous exposure to counseling on obesity. DESIGN: Questionnaire-based survey. SETTING: Gynecology clinics in a large midwestern city. PARTICIPANTS: Non-pregnant women age 18 to 65 years. METHODS: Descriptive design with distribution of anonymous questionnaires pertaining to demographics, current medical conditions, perceived weight, medical conditions associated with obesity, surgical complications from obesity, and previous weight loss counseling. All data were analyzed using chi-squared tests, and statistical significance was set at a p value of <.05. RESULTS: The majority of the sample (65%) was overweight or obese, and 44% of participants underestimated their BMI categories. The relationship of perceived versus actual BMI differed significantly by race (p < .001), income (p < .05), and education (p < .05); African American women and women with less education tended to underestimate their BMI categories. Increasing actual BMI was inversely correlated with the ability to identify obesity as a risk factor for medical conditions (p < .01). Only 43% of participants discussed their weight or related concerns with medical professionals. CONCLUSION: A significant number of participants were unaware of their BMI status as well as the relationship between obesity and other comorbidities. Counseling and patient education efforts by health care providers are essential.

Transvaginal cervical length and amniotic fluid index: can it predict delivery latency following preterm premature rupture of membranes?

OBJECTIVE: We sought to determine whether transvaginal cervical length (TVCL), amniotic fluid index (AFI), or a combination of both can predict delivery latency within 7 days in women presenting with preterm premature rupture of membranes (PPROM). STUDY DESIGN: This was a prospective observational study of TVCL measurements in 106 singleton pregnancies with PPROM between 23-33 weeks. Delivery latency was defined as the period (in days) from the initial TVCL after PPROM to delivery of the infant, with our primary outcome being delivery within 7 days of TVCL. The independent predictability of significant characteristics for delivery within 7 days was determined using multiple logistic regression. Sensitivity, specificity, and predictive values were used to examine whether the presence of a short TVCL, AFI, or a combination of both affected the risk of delivery within 7 days. RESULTS: Delivery within 7 days occurred in 51/106 (48%) of pregnancies. Median duration (interquartile range) from PPROM to delivery and TVCL to delivery was 8 days (4.0-16.0) and 8 days (3.0-15.0), respectively. Using multiple regression TVCL as a continuous variable (odds ratio, 0.65; 95% confidence interval, 0.44-0.97; P < .05), AFI ≤5 cm (odds ratio, 4.69; 95% confidence interval, 1.58-13.93; P < .01) were determined to be independent predictors of delivery within 7 days. In all, 42 women (40%) had a TVCL ≤2 cm, while 62 (59%) had AFI ≤5 cm. A total of 26 women (25%) had a combination of both TVCL ≤2 cm and AFI ≤5 cm, while 28 women (27%) had neither characteristic. The predictive value of delivery within 7 days for a TVCL ≤2 cm was 62%, and for an AFI ≤5 cm was 58%. Having a combination of low TVCL and low AFI did not increase the predictive value of delivery within 7 days (58%). In contrast, only 3 of 27 women (11%) with neither characteristic delivered within 7 days. The predictive value of delivery >7 days for TVCL >2 cm alone was 61%. This predictive value changed when analyzed in conjunction with an AFI ≤5 cm and >5 cm at 42% and 89%, respectively. CONCLUSION: A shorter TVCL and an AFI ≤5 cm independently predict delivery within 7 days in women presenting with PPROM. The combination of an AFI >5 cm and TVCL >2 cm greatly improved the potential to remain undelivered at 7 days following cervical length assessment. These findings may be helpful for counseling and optimizing maternal and neonatal care in women with PPROM.

Gestational weight gain and maternal and neonatal outcomes in term twin pregnancies in obese women.

Limited data is available that estimates the effect of gestational weight gain on maternal and neonatal outcomes in term twin pregnancies in obese women. A historical cohort study of 831 obese (BMI ≥30.0 kg/m2) women in Missouri delivering 1,662 liveborn, term (≥37 weeks gestation) twin infants in 1998-2005 was conducted. Three gestational weight gain categories were examined: <25 pounds, 25-42 pounds, and >42 pounds. Adjusted odds ratios were calculated with multiple logistic regression, using the 2009 Institute of Medicine provisional guideline of 25-42 pounds as the reference group. Significant increasing trends with gestational weight gain were found for preeclampsia (p < .05), larger twin birth weight (p < .01), smaller twin birth weight (p < .001), and infants weighing >2,500 grams (p < .001). Significant increasing trends for preeclampsia and for cesarean delivery were found in concordant twin pairs (smaller twin >80% of birth weight of larger twin). Women who gained >42 pounds had a borderline significantly higher odds of preeclampsia than women who gained 25-42 pounds (adjusted OR 1.72; 95% CI 1.00-2.99, p = .052). No significant differences were found for 1-min Apgar score <4, 5-min Apgar score <7, or infant mortality ≤1 year. Our study suggests that increasing gestational weight gain is associated with larger infants but increased risk of preeclampsia and cesarean delivery in term twin pregnancies in obese women. Limiting gestational weight gain could reduce the risk of preeclampsia and cesarean delivery. Prospective studies of other study populations and maternal/infant outcomes are needed to evaluate the efficacy of the Institute of Medicine guideline.
