Adjusting models to better predict obstetric anal sphincter injury (OASIS) in forceps-assisted vaginal deliveries: Aretrospective cross-sectional trial.

Obesity and maternal age are increasing among pregnant patients. The understood effect of body mass index (BMI), advanced maternal age (AMA), and second stage of labor on obstetric anal sphincter injury (OASIS) at delivery is varied. The objective of this study was to assess whether incorporating BMI, second stage of labor length, and AMA into a model for predicting OASIS among forceps-assisted vaginal deliveries (FAVD) had a higher predictivity value compared to models without these additions. This was an IRB-approved retrospective cohort study of singleton gestations who underwent a FAVD between 2017 and 2021. The primary outcome was prediction of OASIS via established models versus models including the addition of new predictive factors. A total of 979 patients met inclusionary criteria and were included in the final analysis. 20.4% of patients had an OASIS laceration, 11.3% of neonates had NICU admissions, 23.7% had a composite all neonatal outcome, and 8% had a composite subgaleal/cephalohematoma outcome. Comparisons of known factors that predict OASIS (nulliparity, race, episiotomy status) to known factors with additional predictors (BMI, AMA, and length of second stage in labor) were explored. After comparing each model's AUC to one another (a total of 3 comparisons made), there was no statistically significant difference between the models (all P > 0.62). Including BMI, AMA, and second stage of labor length does not improve the predictivity of OASIS in patients with successful FAVD. These factors should not impact a provider's decision to perform a FAVD when solely considering increased odds of OASIS.

Pregnancy Outcomes in Patients with Obstructed Hemivagina Ipsilateral Renal Agenesis

Study ObjectiveObstructed hemivagina with ipsilateral renal agenesis (OHVIRA) is a rare congenital Müllerian anomaly. We sought to explore the impact of OHVIRA on pregnancy outcomes. MethodsA retrospective chart review identified 8 patients with an OHVIRA diagnosis and at least 1 documented pregnancy. Data collected included demographic characteristics, age at diagnosis and repair, gynecologic history, and pregnancy outcomes. Descriptive analysis was performed. ResultsTwenty-three pregnancies were identified among the 8 patients (range 1-5 pregnancies per patient), resulting in 9 term births, 6 preterm births, and 8 first-trimester spontaneous abortions. The most common pregnancy complications were fetal growth restriction (2/15) and preeclampsia with severe features (2/15). The average gestational age at delivery was 37 2/7 weeks; however, 60% (9/15) of live births were at term. Two patients delivered after going into preterm labor, one of whom also had preterm premature rupture of membranes. Of the 15 live births, there were 10 cesarean deliveries, 4 vaginal deliveries, and 1 forceps-assisted vaginal delivery. Three patients (30%) underwent primary cesarean deliveries due to fetal malpresentation. Five live births were repeat cesarean deliveries, and 2 were unscheduled cesareans, at 34 and 36 weeks, due to preeclampsia with severe features. ConclusionThis study is among the first to examine pregnancy outcomes in patients with OHVIRA. Among these patients, there were 23 total pregnancies, with higher incidences of spontaneous abortion, preterm birth, breech presentation, and cesarean delivery compared with the general population. This descriptive data set addresses a knowledge gap to help clinicians more effectively advise patients with OHVIRA about pregnancy outcomes.

Risk factors accounting for anal incontinence during the first year after vaginal delivery-A case control study in China.

Anal incontinence (AI) is a prevalent postpartum disorder. This study aims to investigate and quantify the risk factors for AI in the Chinese population during the first year following vaginal delivery. The case control study was conducted at Peking University Third Hospital, including all women who delivered vaginally between January 1, 2014, and June 30, 2018. Participants were followed up by telephone interviews 1 year after delivery. AI was defined as the involuntary loss of flatus or feces using a retrospective Jorge and Wexner score above 0. Clinical data were retrieved from the medical record system. Univariate and multivariate analyses were applied to identify potential risk factors accounting for AI. Based on the logistic regression model, a nomogram was constructed to predict the probability of AI postpartum. Restricted cubic spline was utilized to explore potential non-linear relationships between birth weight and AI postpartum. Among the 140 AI and 421 none AI cases, we observed antepartum factors like every 100 g of birth weight gain (OR 1.39, 95% CI 1.30-1.49), while intrapartum factors like forceps-assisted vaginal delivery (OR 7.11, 95% CI 2.60-19.45), midline episiotomy (OR 13.11, 95% CI 1.71-100.89), second-degree perineal tear (OR 6.51, 95% CI 1.16-36.68), and third to fourth-degree perineal tear were independent risk factors for postpartum AI. Significantly, infant weighing over 3,400 g at birth increased the risk of AI postpartum. Based on logistic regression model, we constructed a nomogram to estimate the risk of AI 1 year after vaginal delivery. Our findings indicated that during the first year following vaginal delivery, infant with birth weight of 3,400 g or more, forceps-assisted vaginal delivery, midline episiotomy, and second to fourth-degree perineal tear increased the risk of AI. As a result, it is essential to limit the routine use of forceps and midline episiotomy and to monitor fetal weight during prenatal care.

The Effect of Advanced Maternal Age on Adverse Outcomes Among Forceps-Assisted Vaginal Deliveries [ID: 1355950

INTRODUCTION: Delivery rates among patients of advanced maternal age (AMA) are increasing. Prior studies have shown that AMA is associated with increased pregnancy risks and adverse outcomes. This study’s objective was to evaluate whether AMA is associated with an increase in obstetric anal sphincter injury (OASIS) rates among patients who undergo forceps-assisted vaginal deliveries (FAVDs). METHODS: This was an IRB-approved, retrospective cohort study of singleton gestations with FAVD at a single institution between 2017 and 2021. Primary outcome was rate of OASIS among patients with and without AMA. Secondary outcomes included quantitative blood loss (QBL), neonatal composite of subgaleal and cephalohematoma (adverse neonatal composite), and neonatal intensive care unit (NICU) admission. Quantitative blood loss was assessed using Mann-Whitney U test. Remaining outcomes were assessed using multivariate logistic regression models while adjusting for provider clustering and confounding patient characteristics including episiotomy and birth weight. RESULTS: Nine hundred eighty-three records were included, 704 non-AMA and 279 AMA. Patients of AMA were more likely to be Caucasian and were less likely to be Hispanic, nulliparous, experience spontaneous labor, and undergo episiotomy. Patients of AMA did not demonstrate increased odds of OASIS compared to non-AMA patients (odds ratio [OR] 1.21 [0.78, 1.89]). When age was assessed continuously, there was no association between increasing age and rates of OASIS (OR 1.02 [0.98, 1.06]). There was no statistically significant difference in QBL among the two groups (357.0 versus 350.0 cc, P=.20), NICU admission or adverse neonatal composite. CONCLUSION: Advanced maternal age does not appear to be a risk factor for OASIS or other adverse outcomes in patients undergoing FAVD.

Effects of Different Indications for Forceps Delivery on Pelvic Floor Muscle Surface Electromyography and Early Postpartum Pelvic Floor Function in Primiparas

Background: Forceps-assisted vaginal delivery is closely associated with postpartum pelvic floor muscle (PFM) injury and postpartum pelvic floor dysfunction. The present study utilized Glazer PFM surface electromyography (sEMG) and International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF) for the objective assessment of postpartum PFM function to determine the effects of different forceps delivery indications on early postpartum pelvic floor function in primiparas. Methods: Four hundred primiparas whose pregnancies had been terminated by forceps delivery were divided into three groups based on the indication for forceps delivery: fetal distress (FD) (n = 260), prolonged second stage of labor (PSSL) (n = 30), and intrapartum fever combined with fetal distress (IFFD) (n = 110). Pelvic floor muscle surface electromyography (EMG) performed according to the Glazer protocol at 42–60 days postpartum was the primary outcome measure. Results: The overall Glazer assessment scores of the PSSL (54.4 ± 18.6) and IFFD (54.6 ± 15.8) groups were significantly lower than that of the FD group (59.3 ± 17.0) (p = 0.019). The peak EMG value during the fast-twitch stage for the FD, PSSL, and IFFD groups was 32.4 ± 17.7, 31.7 ± 26.1, and 26.5 ± 12.2 μV, respectively; the IFFD and FD groups were significantly different (p < 0.05). The incidence of postpartum stress urinary incontinence (SUI) was significantly higher in the IFFD and PSSL groups; the IFFD and FD groups were significantly different (p < 0.05). Conclusions: Intrapartum fever probably affects the early postpartum pelvic floor function of primiparas who underwent forceps delivery, which mainly manifests in the short term as reduced fast-twitch muscle strength and SUI.

Is second stage of labor duration associated with adverse outcomes among forceps assisted vaginal deliveries?

Previous studies have suggested that both precipitous labor and increased duration of second stage of labor are risk factors for obstetric anal sphincter injury (OASIS) at time of vaginal delivery. We sought to assess if increasing duration of second stage of labor is associated with OASIS in patients undergoing forceps assisted vaginal delivery (FAVD).

Operative Vaginal Birth: Neonatal Implications for Vacuum and Forceps-Assisted Vaginal Delivery

Rapid Cycle Deliberate Practice Versus Traditional Simulation to Improve Resident Performance in Forceps Deliveries

This study aimed to assess the effectiveness of rapid cycle deliberate practice (RCDP) in improving obstetrics and gynaecology residents’ performance and skill retention in forceps-assisted vaginal deliveries. Thirty-three residents were randomly assigned to RCDP or traditional debriefing. Performance was evaluated using an objective structured assessment of technical skills (OSATS) tool. There were no significant differences in immediate performance scores between groups (P = 0.082). At 4–6 months, both groups demonstrated improved performance scores (traditional, P = 0.001; RCDP, P = 0.001). Seventy-six percent of residents in the RCDP group indicated “real-time” feedback was advantageous. Three residents suggested this method was less beneficial at a senior level.

Rapid Cycle Deliberate Practice Versus Traditional Simulation to Improve Resident Performance in Obstetrical Emergencies

Rapid Cycle Deliberate Practice (RCDP) is a novel simulation strategy wherein participants cycle between deliberate practice and feedback within the simulation scenario to achieve skill acquisition. Our aim was to assess the effectiveness and feasibility of RCDP in improving obstetrics and gynaecology residents’ performance and skill retention compared to traditional debriefing in a forceps assisted vaginal delivery (FAVD) simulation.

Identification of Essential Steps in Outlet Forceps-Assisted Vaginal Delivery: A Delphi Study

ObjectiveTo achieve expert consensus using the Delphi methodology on the sub-steps considered essential in an outlet forceps-assisted vaginal delivery (FAVD). The purpose of this work is to help inform a framework for standardized training and objective assessment in the procedure. MethodsA Delphi survey was conducted with an international panel of experts in FAVD. Using an online platform, experts rated sub-steps of FAVD on a 5-point Likert scale to indicate whether they considered them essential. Responses were returned to the panel until consensus was reached (Cronbach α ≥ 0.80) with an intraclass correlation coefficient ≥0.75. All sub-steps with a rate of agreement ≥80% are proposed to be included in a future evaluation instrument. ResultsAfter the first iteration of the Delphi procedure, a response rate of 42% was reached (n = 21); the second iteration was only sent to those who had participated in the initial iteration, reaching a response rate of 100%. Of 42 sub-steps rated in the first round, 24 (57.1%) achieved consensus, 8 (19%) were rejected, and 10 (23.8%) were re-rated in the second round. After 2 iterations, 28 sub-steps were agreed upon by the experts to be essential in FAVD. ConclusionsA panel of experts identified a total of 28 sub-steps essential to FAVD. This list could inform the development of an objective assessment framework and evaluation tool for this procedure. Further research should focus on the standardization, applicability, validation, and introduction of this tool in medical training, with a focus on real-life, high-fidelity simulation and online educational tools.

Association between second stage of labour length and risk of obstetrical anal sphincter injury in nulliparous women: a population-based retrospective cohort study.

Obstetrical anal sphincter injury (OASIS) is a common consequence of vaginal delivery in nulliparas and carries the risk of short- and long-term morbidity. The objective of this study was to estimate the association between the duration of the second stage of labour and OASIS risk. A population-based, retrospective cohort of nulliparas delivering singleton, vertex, non-anomalous fetuses at term in Nova Scotia, Canada, from 2005 to 2019, were identified using the Nova Scotia Atlee Perinatal Database. Poisson regression models were used to estimate risk ratios (RR) with robust 95% confidence intervals (CI) adjusting for confounding variables to investigate the association between the length of the second stage and OASIS in the entire cohort and in operative vaginal deliveries. Of 36,662 participants, 7.6% sustained an OASIS (6.8% third-degree, 0.8% fourth-degree tear). The proportion of participants who sustained an OASIS increased over the study period. For each 30-min increase in the length of second stage, the OASIS risk increased by 11% (RR 1.11, 95% CI 1.10-1.12). When stratified by mode of delivery, second stage length ≥ 90min was associated with an increased OASIS risk in spontaneous (RR 1.35, 95% CI 1.15-1.58) and vacuum-assisted vaginal deliveries (RR 1.42, 95% CI 1.11-1.81). In forceps-assisted vaginal deliveries, OASIS risk was increased, with shorter and longer durations of the second stage. Increasing length of the second stage of labour was associated with increasing risk of OASIS overall, but the association was heterogeneous between modes of delivery. Length of the second stage should be considered in counseling about OASIS risk.

Resident and program director confidence in resident preparedness for operative vaginal deliveries in Obstetrics and Gynecology Training Programs in the United States

Operative vaginal delivery is used to expedite a safe vaginal delivery in the second stage of labor and is considered an essential part of residency training in obstetrics and gynecology. To assess the self-reported readiness of obstetrics and gynecology residents in the United States to perform vacuum-assisted vaginal delivery and forceps-assisted vaginal delivery compared with the perceptions of program directors. The Council on Resident Education in Obstetrics and Gynecology surveyed the residents in all US training programs about their readiness to perform forceps-assisted and vacuum-assisted deliveries. The program directors were simultaneously surveyed about the readiness of their cohort to perform operative deliveries with and without attending oversight. The primary outcome of the survey was the residents' self-reported confidence in their ability to autonomously and independently perform operative deliveries. Α total of 5084 out of 5514 (92.9%) resident physicians and 241 out of the 292 (83%) residency program directors completed the survey. Eighty-seven percent (95% confidence interval, 84.9-88.9) of the graduating residents reported feeling that they could autonomously perform a vacuum-assisted vaginal delivery, compared with 49.5% (95% confidence interval, 46.6-52.4) for forceps-assisted vaginal delivery (P<.01). Similarly, whereas 95.9% (95% confidence interval, 94.6-97.0) of the residents felt that they could confidently perform an emergency vacuum-assisted vaginal delivery, only 42.3% (95% confidence interval, 39.4-45.2) felt confident performing an emergency forceps-assisted vaginal delivery (P<.01). The residency program directors significantly overestimated their residents' confidence in independently performing an emergency forceps-assisted vaginal delivery or vacuum-assisted vaginal delivery than the residents themselves (54% [95% confidence interval, 47.1-60.5] vs 24% [95% confidence interval, 22.5-24.9] and 98.6% [95% confidence interval, 97.0-100] vs 71.9 [95% confidence interval, 70.6-73.2] respectively P<.01). Trainees in military-based residency programs and those interested in pursuing a career as generalists or maternal-fetal medicine specialists reported significantly higher preparedness to perform a forceps-assisted vaginal delivery. Graduating obstetrics and gynecology residents report feeling less prepared to independently perform a forceps-assisted vaginal delivery than a vacuum-assisted vaginal delivery. The program directors had more confidence in the ability of their residents to perform an operative vaginal delivery than the residents themselves.

Reported case numbers and variability in delivery route and volume by obstetrics and gynecology residents from 2003 to 2019

The obstetrical landscape in the United States has changed over the past several decades, during which there has been a decline in the number of operative vaginal deliveries performed. Procedural cases of obstetrics and gynecology residents are tracked in the Accreditation Council for Graduate Medical Education database, with a minimum requirement of 15 operative vaginal deliveries before graduation. Nowadays, it is unknown whether the decreasing numbers of operative vaginal deliveries are affecting the delivery case volume and experience of obstetrics and gynecology residents. This study aimed to analyze the trends in the number and route of obstetrical deliveries, including operative vaginal deliveries, performed by graduating obstetrics and gynecology residents in the United States as logged within the Accreditation Council for Graduate Medical Education database. The Accreditation Council for Graduate Medical Education case log data were examined for graduating obstetrics and gynecology residents between 2003 and 2019. Delivery case volume numbers for spontaneous vaginal delivery, cesarean delivery, forceps-assisted vaginal delivery, and vacuum-assisted vaginal delivery were extracted and analyzed over time using linear regression. To compare the variability in logged cases, residents at the 70th percentile for number of cases logged were compared with residents at the 30th percentile for number of cases logged for each delivery type (spontaneous vaginal delivery, cesarean delivery, forceps-assisted vaginal delivery, and vacuum-assisted vaginal delivery). Overall, obstetrical delivery data for 20,268 obstetrics and gynecology residents were collected from 2003 to 2019. Over this period, the mean number of spontaneous vaginal deliveries significantly decreased over time by 20% from 320.8±138.7 to 256.1±75.6 (slope, -2.6; P<.001); however, no significant difference was noted in the reported cesarean delivery cases, with an 8% increase from 191.8±80.1 to 206.8±69.7 per graduating resident (slope, 0.136; P=.873). Notably, the mean reported cases of forceps-assisted vaginal deliveries decreased by 75% from 23.8±21.9 to 6±6.8 per graduating resident (slope, -0.851; P<.001). Similarly, the mean logs of vacuum-assisted vaginal delivery decreased by 37% from 23.8±17.1 to 15±9.5 (slope, -0.542; P<.001). The ratio of reported resident case logs comparing the volume at the 70th percentile with the volume at the 30th percentile demonstrated a significant decrease over time for spontaneous vaginal delivery (slope, -0.015; P<.001), cesarean delivery (slope, -0.015; P<.001), and vacuum-assisted vaginal delivery (slope, -0.033; P<.001) but was significantly increased for forceps-assisted vaginal delivery (slope, 0.07, P=.0065). In the reported Accreditation Council for Graduate Medical Education case logs, we identified that the reported number of obstetrical deliveries performed by obstetrics and gynecology residents in the United States is changing, with a significant decline recognized from 2003 to 2019 in logged numbers of spontaneous vaginal deliveries, vacuum-assisted vaginal deliveries, and forceps-assisted vaginal deliveries, without a difference in reported cesarean delivery cases per graduating resident. Furthermore, substantial variation is seen among resident volume nationwide, with the difference in high- and low-volume resident forceps-assisted vaginal delivery experience increasing over time. Awareness of these data should notify the Accreditation Council for Graduate Medical Education and educators about reasonable targets, increased need for simulation, and new ways to teach all modes of deliveries effectively in all residency programs.

Using Motion Tracking to Analyze Forceps Paths During Simulated Forceps-Assisted Vaginal Deliveries.

The purpose of this study was to evaluate the ability of motion tracking to discern variation in forceps paths during standardized simulated forceps-assisted vaginal deliveries among experienced and inexperienced obstetric providers. This is a pilot study involving 24 obstetrics and gynecology residents and 6 faculty at a single institution. Each participant was filmed performing standardized simulated forceps-assisted vaginal deliveries on a high-fidelity model. Motion tracking software (Kinovea, Medoc, France) was used to track the path of the forceps shank. Data were analyzed for total path length, total x-plane displacement, total y-plane displacement, and final forceps angle. One-way analysis of variance was used to evaluate for statistically significant differences between groups based on education year, with Turkey HSD post hoc test to identify interactions. Statistically significant differences were noted between groups in the total path length (F = 7.57, P < 0.001) and total y-plane displacement (F = 5.79, P < 0.001). On pairwise comparison, significant differences were noted between faculty and postgraduate year 1 as well as faculty and postgraduate year 2 for total y-plane displacement and total path length. Significant differences were not observed between groups for total x-plane displacement (F = 0.89, P = 0.475) and final forceps angle (F = 2.45, P = 0.052). Motion tracking of standardized simulated forceps-assisted vaginal deliveries identifies statistically significant differences between experienced and inexperienced obstetric providers. Our findings suggest that motion tracking can be used to design an educational intervention to improve forceps technique among obstetrics and gynecology residents.

Congenital Facial Palsy- A Rare Case Report

Congenital facial palsy is a very rare entity with an incidence of 2 per 1000 live births. It can be congenital, traumatic associated with birth trauma in the form of forceps delivery or developmental. We present the case of a 1-year-old girl who presented to the eye department of our tertiary care hospital with a deviation of face to the right side since birth along with watering of left eye and difficulty in taking feeds. There was a history of forceps-assisted vaginal delivery; a provisional diagnosis of congenital facial palsy was done with the probable cause of trauma.

Adding Insult to Injury: Levator Ani Avulsion in Women With Obstetric Anal Sphincter Injuries.

In women with obstetric anal sphincter injuries, we compared the rate of major levator ani avulsion after forceps-assisted delivery versus spontaneous vaginal delivery. Prospective cohort of primiparous women with obstetric anal sphincter injuries. The primary outcome was the rate of major levator ani avulsion as measured by 3-dimensional transvaginal ultrasonography performed between 1 and 2 weeks postpartum. Secondary outcomes included ultrasonographic anteroposterior hiatal diameter, levator hiatal area, and levator-urethra gap, and differences in validated pelvic disorder questionnaires scores at 1 to 2 and 13 weeks postpartum. Sixty-two women (30 spontaneous deliveries, 32 forceps deliveries) were included in the final analysis. After controlling for delivery variables, women who underwent forceps-assisted delivery were more likely to experience a major avulsion as compared with those who underwent spontaneous delivery (21/32, [65.6%] vs 8/30 [26.7%]; odds ratio, 5.9; 95% confidence interval, 1.5-24.5; P = 0.014). They were also more likely to have larger levator-urethra gaps bilaterally (P = 0.012, 0.016). After controlling for potential confounders, levator ani avulsion was independently associated with persistent anal incontinence symptoms at 13 weeks postpartum (P = 0.02). In women with obstetric anal sphincter injuries, the risk of levator ani avulsion is almost 6 times higher after forceps-assisted vaginal delivery as compared with spontaneous vaginal delivery. In those with avulsion, recovery of anal continence is compromised, suggesting that adding insult (avulsion) to injury (obstetric anal sphincter injury) may have negative functional consequences.

Early Secondary Repair of Obstetric Anal Sphincter Injury Breakdown: Contemporary Surgical Techniques and Experiences From a Peripartum Subspecialty Clinic.

To describe surgical technique and outcomes of early secondary repair of obstetric anal sphincter injury (OASIS) breakdown. This was a case series of all women presenting to a subspecialty peripartum clinic within 2 months of an OASIS, who ultimately underwent secondary surgical repair between September 2013 and January 2018. Cases were identified using the following CPT codes: 57308 (transperineal fistula repair), 56910 (repair of the perineum), and 46750 (repair of anal sphincter). Four board-certified urogynecologists performed all surgical procedures using the same technique: demographics, delivery data, and preoperative and postoperative data were collected. Eighteen women were identified. The majority (16 [88.9%] of 18) were primiparous; 9 (50%) women underwent spontaneous vaginal delivery and 9 (50%) women underwent forceps-assisted vaginal delivery. Over 70% (13 [72.2%] of 18) suffered a 3rd-degree tear, whereas 5 (27.8%) of 18 had a 4th-degree laceration. The median time after delivery to specialty clinic presentation was 10 days (interquartile range, 5.3-52.5 days). All women were diagnosed with wound breakdown at their initial visit. Seven (38.9%) also had a concomitant rectovaginal fistula.Median time from diagnosis of wound breakdown to secondary operative revision was 19.5 days (interquartile range, 12-26.8 days). Seventeen (94.4%) of the 18 women underwent overlapping external anal sphincteroplasty with perineorrhaphy; of these, 7 (41.2%) also underwent concurrent repair of their rectovaginal fistula. One woman underwent perineorrhaphy alone. At 3 months postoperatively, no women had a wound breakdown or recurrent fistula. In women with OASIS breakdown, early secondary repair is both feasible and successful with meticulous surgical technique.

Preferences and comfort of maternal fetal medicine fellows in the United States with operative vaginal deliveries

Objective The objective of this study was to determine the current landscape of vacuum and forceps-assisted vaginal delivery (FAVD) preferences and comfort across maternal fetal medicine (MFM) fellows in the United States (U.S.). Methods A survey was sent to MFM fellowship program directors for distribution to current MFM fellows across U.S. Geographic regions, as determined using Census Bureau-designated regions. The survey looked at comfort and experience with FAVDs and vacuum-assisted vaginal deliveries (VAVD) throughout their post-graduate training. Descriptive statistics were used to analyze survey responses. Respondents were compared by post-graduate year (PGY) and region. Results One hundred six MFM fellows (32%) completed the survey. 22.6% of MFM fellows had performed greater than 30 FAVDs, with 33% having performed ≤10 FAVDs. In comparison, 35.8% of fellows had performed more than 30 VAVDs. While 95.2% of fellows feel prepared to perform a VAVD independently, only 59.4% feel prepared to do FAVDs independently. Never the less, 53% of MFM fellows favor performing a FAVD. While some regional differences were seen, there was no significant difference in the percent of fellows by geographic region who have performed >30 FAVD (p = .87). MFM fellows in the West are most likely to have performed >30 FAVD at 57.8%, compared to 42.3, 35, and 11.4% in the Midwest, South, and Northeast, respectively. Conclusion MFM fellows are more confident with VAVD compared to FAVD. Despite feeling less confident performing FAVD (versus VAVD), the majority of MFM fellows feel comfortable performing FAVDs independently. Region of training fellowship training does not significantly affect one’s confidence in FAVDs. A coordinated nationwide effort to increase exposure to and confidence for FAVDs should be considered.

Episiotomy-site clear cell carcinoma

A 54-year-old woman complained of a 7 cm posterior vulvoperineal mass, initially labeled as a Bartholin’s gland cancer. Her obstetric history revealed a forceps-assisted vaginal delivery with a large episiotomy. Physical exam showed a partially mobile tumor with normal overlying skin and absent inflammatory signs, sparing both the anus and vagina (Figure 1). No enlarged inguinal lymph nodes were identified. Magnetic resonance imaging confirmed a complex lesion located at the right ischioanal fossa, suggestive of malignancy (Figure 2).

Resident Operative Vaginal Delivery Volume after Educational Curriculum Implementation.

The percentage of operative vaginal deliveries (OVDs) in the United States has sharply declined. In May 2016, our institution's obstetrics and gynecology (OB/GYN) residency program implemented a twice-yearly OVD curriculum consisting of didactics and simulation. We sought to evaluate the impact of this curriculum. We performed a retrospective cohort study of all deliveries at our institution from July 2011 to May 2018. Deliveries were evaluated quarterly for the pre- (July 2011-April 2016) and postcurriculum (July 2016-May 2018) periods. Forceps-assisted vaginal delivery (FAVD), vacuum-assisted vaginal delivery (VAVD), and total OVD percentages, and the ratio of forceps to vacuums were calculated. Pre- and postcurriculum percentages were compared using Wilcoxon's rank-sum test. Cubic regression curves were fit to quarterly percentages to illustrate trends over time. The quarterly OVD percentage was unchanged following curriculum implementation (mean 3.2% [Q1-Q3: 2.6-3.5%] pre- vs. 3.1% [2.5-3.8%] post-, p > 0.99). The FAVD percentage was increased (1.2% [0.8-1.5%] vs. 2.0% [1.4-2.6%], p = 0.027) and the VAVD percentage was decreased (2.0% [1.6-2.2%] vs. 1.2% [0.9-1.3%], p < 0.001). This was accompanied by an increase in the ratio of FAVD to VAVD (0.6 [0.4-0.8] vs. 1.7 [1.3-2.2], p < 0.001). FAVD percentage (3.1%) was higher in the last quarter than any other quarter in the 7-year study period, and total OVD percentage (3.9%) was higher in 2018 than any other calendar year. The implementation of an OVD curriculum in our OB/GYN residency program resulted in an increase in the percentage of FAVD and the ratio of FAVD to VAVD. · OVD utilization in the United States continues to decline.. · We demonstrate real-world impact of an OVD curriculum.. · OVD curriculum implementation increases usage of FAVD..
