Effect of Preoperative Bilateral Ultrasound-guided Quadratus Lumborum Nerve Block on Quality of Recovery after Minimally Invasive Hysterectomy in an Enhanced Recovery after Surgery (ERAS) Setting.

STUDY OBJECTIVE: To assess the effect of preoperative bilateral ultrasound-guided quadratus lumborum nerve block (QLB) on quality of recovery after minimally invasive hysterectomy, in an enhanced recovery after surgery setting. DESIGN: Randomized, controlled, double-blinded trial (Canadian Task Force level I). SETTING: University-affiliated tertiary medical center. PATIENTS: All women undergoing an elective robotic or laparoscopic hysterectomy. Women with chronic pain, chronic anticoagulation, and body mass index >50 kg/m2 were excluded. INTERVENTION: Patients were randomized with a 1:1 allocation, to one of the following 2 arms, and stratified based on robotic versus laparoscopic approach. 1. QLB: QLB (bupivacaine) + sham local trocar sites infiltration (normal saline) 2. Local infiltration: sham QLB (normal saline) + local infiltration (bupivacaine) MEASUREMENTS AND MAIN RESULTS: The primary outcome was defined as the quality of recovery score based on the validated questionnaire Quality of Recovery, completed 24 hours postoperatively. Secondary outcomes included dynamic pain scores, accumulated opioid consumption up to 24 hours, postoperative nausea and vomiting, surgical complications, length of hospital stay, time to first pain medication administration in the postanesthesia care unit, and adverse events. A total of 76 women were included in the study. Demographic characteristics were similar in both groups. Median age was 44 years (interquartile range 39-50), 47% of the participants were African American, and mean body mass index was 32.8 kg/m2 (standard deviation [SD] 8.1). The mean Quality of Recovery score was 179.1 (SD ± 10.3) in the QLB and 175.6 (SD ± 9.7) for the local anesthesia group (p = .072). All secondary outcomes were comparable between groups. CONCLUSIONS: QLBs do not significantly improve quality of recovery after elective robotic or laparoscopic hysterectomy compared with local anesthetic port site infiltration.

The association between BMI and continuity of etonogestrel (ENG)-releasing implant.

OBJECTIVE: The etonogestrel-releasing implant is a long-acting reversible contraception that is recommended by the Food and Drug Administration for 3 years and has been proven to be highly effective and convenient. Adverse effects including irregular bleeding patterns, weight gain, and acne are reported to be the main reasons for treatment discontinuation. The aim of this study is to learn the association between body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) and the incidence of side effects and adherence to treatment. METHODS: This is a retrospective cohort study, conducted at a single university-affiliated medical clinic, including all women who underwent etonogestrel-releasing implant (Nexplanon®; New Jersey, USA, Organon USA Inc., Merck and Co) insertion between January 2019 and December 2021. Cases where abnormalities were reported during the insertion procedure or missing data were excluded from the study. Information on patients' demographic, medical history, obstetric and gynecological history, and follow-up was collected from electronic medical files. The primary outcome was defined as the rate of implant removal in the different obesity classes. Data are presented as median and interquartile range. The study was approved by institutional review board. RESULTS: The study population included 1318 women, of whom 466 (35%) requested early removal of the implant. Women's demographic and clinical characteristics were comparable between women who requested early removal and those with full-length treatment. The median time for early removal was 12 (6-20) months from insertion. Irregular bleeding was the most frequent reason for early removal in both groups and was more than twice as prevalent in the early removal group (239 [51.29%] vs 193 [22%], P = 0.001). The early removal group had fewer obese women (BMI ≥30) compared with women who had full-length treatment (163 [31.8%] vs 350 [68.2%], P = 0.03), with comparable rates of class 3 obesity women (BMI ≥40) (P = 0.68). Multi-regression logistic analysis including age, BMI, parity and side effects found that the presence of side effects is the only independent predictor significantly associated with early implant removal (B = 1.74, P = 0.04). CONCLUSIONS: Continuation of etonogestrel-releasing implant contraception treatment was associated with the presence of side effects that were more often reported in non-obese women. BMI was not found to be a significant factor influencing adherence to treatment.

Excess use of surgical supplies in minimally invasive benign gynecology surgery: an observational study.

BACKGROUND: Single-use materials and equipment are regularly opened by the surgical team during procedures but left unused, potentially resulting in superfluous costs and excess environmental waste. OBJECTIVE: This study aimed to estimate the excess use of surgical supplies in minimally invasive benign gynecologic surgeries. STUDY DESIGN: This is a prospective observational study conducted at a university-affiliated single tertiary medical center. Designated study personnel were assigned to observe surgical procedures performed during July to September 2022. Surgical teams were observed while performing surgeries for benign indications. The teams were not informed of the purpose of the observation to avoid potential bias. Disposable materials and equipment opened during the procedure were documented. Excess supplies were defined as those opened but left unused before being discarded. Costs per item of the excess supplies were estimated on the basis of material and equipment costs provided by the hospital. RESULTS: A total of 99 surgeries were observed, including laparoscopic (32%), robotic (39%), hysteroscopic (14%), vaginal (11%), and laparotomy procedures (3%). Excess use of surgical supplies was documented in all but one procedure. The total cost across all surgeries reached $6357. The contained tissue extraction bag was the most expensive item not used (Applied Medical, Rancho Santa Margarita, CA; $390 per unit) in 4 procedures, contributing 25.54% to the total cost. Raytec was the most common surgical waste, with a total of n=583 opened but unused (average n=5.95 per surgery). A significant difference was found in the rate of excess supplies across the surgical approaches, with robotic surgery contributing 52.19% of the total cost (P=.01). CONCLUSION: Excess use of disposable materials and equipment is common in minimally invasive benign gynecologic surgeries and contributes to superfluous costs and excess environmental waste. It is predominantly attributed to the opening of inexpensive materials that are left unused during the procedure. Increased awareness of costs and generated waste may reduce excess use of surgical supplies and should be further explored in future research.

Preterm cesarean delivery for nonreassuring fetal heart rate tracing: Risk factors and predictability of adverse outcomes.

OBJECTIVE: To compare adverse outcomes among preterm births that underwent cesarean delivery (CD) for non-reassuring fetal heart rate tracing (NRFHT) versus those that did not. STUDY DESIGN: Consortium on Safe Labor Database was utilized for this secondary analysis. Inclusion criteria were non-anomalous, singleton at 23.0 to 36.6 weeks who labored for at least 2 h. Composite adverse neonatal outcomes included any of the following intraventricular hemorrhage grade III or IV, seizures, mechanical ventilation, sepsis, necrotizing enterocolitis 2 or 3, or neonatal death. Composite adverse maternal outcomes included any of the following postpartum hemorrhage, endometritis, blood transfusion, chorioamnionitis, admission to intensive care unit, thromboembolism, or death. RESULTS: Of 228,438 births, 29,592 (13.0%) delivered preterm, and 16,679 (56.4%) labored for at least 2 hrs. CD for NR FHRT was done in 1,220 (7.3%). The rate of composite adverse neonatal outcome was different among those that had CD for NR FHRT (26.7%) versus those that did not (16.6%; aRR 1.59, 95% CI 1.43-1.76). Composite adverse maternal outcomes did not differ between the groups. The area under the curve for risk factors to identify composite adverse neonatal outcome was 0.81, and for composite adverse maternal outcomes, 0.64. CONCLUSIONS: Subsequent to CD for NR FHRT, composite adverse neonatal outcome is 59% higher among preterm births when compared to delivery with reassuring tracing; composite adverse maternal outcomes did not differ between the groups.

Utility of Vaginal Natural Orifice Transluminal Endoscopic Surgery for Permanent Sterilization after Failed Attempt at Bilateral Tubal Ligation at the Time of Previous Cesarean Section.

STUDY OBJECTIVE: To demonstrate the utility of vaginal natural orifice transluminal endoscopic surgery (vNOTES) for opportunistic bilateral salpingectomy for permanent sterilization after a failed attempt at bilateral tubal ligation at the time of previous cesarean section. DESIGN: Stepwise demonstration with narrated video footage. SETTING: There is evidence to support the statistically significant superiority of vNOTES compared with conventional laparoscopy (CL) in terms of patient satisfaction, postoperative pain, time to recovery, and cosmetic results in bilateral salpingectomies for permanent sterilization [1]. Limited studies demonstrate the ease and safety of access to the abdominal cavity in vNOTES while avoiding passage through the abdominal wall, port site complications (infection, hernia, etc.), and those associated with peritoneal adhesions during abdominal laparoscopy or laparotomy [2]. To the best of our knowledge, this would be the first published video of a vNOTES bilateral salpingectomy performed specifically in a patient whose previously attempted bilateral tubal ligation was unsuccessful owing to adhesive disease from 4 previous cesarean sections. INTERVENTIONS: Institutional review board approval was not required. We describe a case of a 31-year-old female, with a history of 4 previous cesarean deliveries and a cholecystectomy, who desired permanent sterilization 3 months after the previous cesarean section. During previous cesarean section, bilateral adnexa were unable to be accessed owing to dense adhesions from previous surgeries. The patient was counseled on various forms of reversible contraceptive methods; however, she desired permanent sterilization with a surgical procedure. She was counseled on the various routes for opportunistic salpingectomy. Risks, benefits, and alternatives of each surgical approach were discussed. The patient consented for vNOTES opportunistic salpingectomy and possible CL. She was aware that she had significant adhesive disease at the time of previous cesarean section, so may potentially require a laparotomy for the procedure. However, she refused a laparotomy if the surgery was unable to be performed minimally invasively. (1) Demonstrate setup of transvaginal access platform for vNOTES bilateral salpingectomy. (2) Abdominal survey and appreciation of severe adhesive disease through posterior cul-de-sac. (3) Bilateral salpingectomy through single-site vaginal natural orifice surgery. CONCLUSION: vNOTES bilateral salpingectomy can be considered as a reasonable alternative to CL in patients with severe abdominal adhesive disease from previous surgeries.

Remdesivir use in pregnancy during the SARS-CoV-2 pandemic.

OBJECTIVE: To ascertain the composite maternal and neonatal outcomes in pregnant individuals with moderate, severe, or critical coronavirus disease 2019 (COVID-19) treated with remdesivir. MATERIALS AND METHODS: This is a secondary analysis of the COVID in Pregnancy Registry in Houston, Texas. Women were included if they met the criteria of moderate, severe or critical COVID-19 illness. Composite adverse maternal outcome was defined as any of the following outcomes: placental abruption, pregnancy-related hypertension, chorioamnionitis, stroke, delivery with estimated blood loss >1000 mL, diagnosis of pulmonary embolism or deep venous thromboembolism, or maternal death. Composite adverse neonatal outcome was defined as any of the following: Apgar score ≤3 at 5 min, arterial cord pH <7.0, positive SAR-CoV-2 test, intraventricular hemorrhage, periventricular leukomalacia, stillbirth, or neonatal death. Comparative analyses between participants receiving remdesivir versus those not exposed were performed. RESULTS: A total of 994 patients were diagnosed with COVID-19 infection. Of these, 95 (9.6%) met criteria for moderate, severe, or critical disease. Forty-one percent of these patients (n = 39) received remdesivir. Baseline demographic characteristics were not different between groups. No patients reported an allergic reaction with the administration of remdesivir; however, 16.7% of the patients had the medication discontinued due to transaminitis. Patients receiving the drug were more likely to have a longer illness duration on admission, more likely to require oxygen support on arrival and have a longer hospital stay. CONCLUSIONS: Remdesivir appears to be safe, well tolerated within our cohort with no cases of recorded adverse reaction.

Chorioamnionitis and adverse outcomes in low-risk pregnancies: a population-based study.

OBJECTIVE: To compare the composite neonatal and maternal adverse outcomes among low-risk pregnancies with versus without chorioamnionitis. METHODS: We conducted a retrospective cohort study using U.S. Vital Statistics Data. The study population was restricted to full term, low-risk, singleton pregnancies. Pregnancies were categorized into those affected and unaffected by chorioamnionitis. The primary outcome was composite neonatal adverse outcome and the secondary outcome was composite maternal adverse outcome. Multivariable Poisson regression models with robust error variance were used to examine the factors associated with chorioamnionitis and to evaluate the association between chorioamnionitis and adverse outcomes [using adjusted relative risk (aRR) and 95% confidence interval (CI)]. RESULTS: Of 19.7 million live births, 59.4% met inclusion criteria; among them, 1.7% were complicated by chorioamnionitis. The risk of composite neonatal adverse outcome was higher in newborns delivered by women with chorioamnionitis (aRR = 3.40; 95% CI = 3.30-3.49). Compared to women without chorioamnionitis, those with chorioamnionitis had a higher risk of composite maternal adverse outcome (aRR = 2.42; 95% CI = 2.31-2.55). Infant mortality was also higher in affected pregnancies (aRR = 1.23; 95% CI = 1.09-1.38). CONCLUSION: Among low-risk pregnancies, chorioamnionitis is associated with a higher risk of composite neonatal and maternal adverse outcomes. Infant death is also increased.

Cesarean delivery at term for non-reassuring fetal heart rate tracing: risk factors and predictability.

OBJECTIVE: To delineate risk factors for adverse outcomes among those who underwent cesarean delivery (CD) for non-reassuring fetal heart rate tracing (NRFHT) and ascertain whether neonatal or maternal morbidity can be predicted accurately. METHODS: The Consortium on Safe Labor Database was utilized for this secondary analysis. Inclusion criteria were non-anomalous, singleton gestations between 37.0 and 41.6 weeks who underwent CD for NRFHT. Composite adverse neonatal outcomes (CANO) included Apgar <5 at 5 min, seizures, mechanical ventilation, sepsis, intraventricular hemorrhage, necrotizing enterocolitis or neonatal death. Composite adverse maternal outcomes (CAMO) included endometritis, blood transfusion, wound complication, admission to intensive care unit, thromboembolism, hysterectomy or death. Bivariable analysis and multivariable Poisson regression were used to identify risk factors independently associated with adverse outcomes. Receiver operating characteristic (ROC) curves were created to evaluate the predictive value of the models for adverse outcomes. RESULTS: Of 228,438 births in the database, 7310 individuals (3.7%) met inclusion criteria. Among this cohort, CANO occurred 3.8% of the time. CANO was less common among people over 35 years (9.8% versus 18.4% p < .01) but was more common among those with at least high-school education (15.3% versus 11.2%; p < .01), varying by ethnicity (p < .01). CAMO occurred in 3.4% and was less common among those undergoing induction of labor (37.3% versus 49.4%; p < .01) and more common among those with clinical chorioamnionitis (8.4% versus 4.3%; p < .01). The area under the curve (AUC) for ROC curve to identify CANO was 0.63 implying a limited ability to predict neonatal adverse outcomes. The AUC for identifying women with maternal adverse outcomes was 0.69 also indicating a moderate prediction ability. CONCLUSIONS: Among singletons between 37 and 41 weeks who labored, the rate of CD for NRFHT was about 3.7% and among them CANO occurred in 3.8%. While risk factors for adverse neonatal outcomes following CD for NRFHT are identifiable, they do not suffice to predict them.

Management and reproductive counseling in cervical, caesarean scar and interstitial ectopic pregnancies over 11 years: identifying the need for a modern management algorithm.

STUDY QUESTION: Do management strategies (treatment type and order), including provision of reproductive counseling, differ in patients with non-tubal pregnancies? SUMMARY ANSWER: Medical and surgical treatment strategies varied widely for each type of non-tubal pregnancy and reproductive counseling in this patient population is lacking. WHAT IS KNOWN ALREADY: Owing to the rarity of non-tubal pregnancies, there is no consensus regarding treatment strategies or protocol. Furthermore, there is limited data on how patients with a non-tubal pregnancy are counseled about future fertility. STUDY DESIGN SIZE DURATION: This is a descriptive retrospective study. Data were collected from January 2006 to December 2017. A total of 50 patients were included in the study. PARTICIPANTS/MATERIALS SETTING METHODS: Patients with an ultrasound diagnosis of a non-tubal ectopic pregnancy (e.g. cervical ectopic pregnancy [CEP], Caesarean scar pregnancy [CSP] or interstitial ectopic pregnancy [IEP]) were included. This study was performed at a university-based institution tertiary referral center. Demographic and clinical characteristics, treatment type and order, reproductive counseling and outcomes were collected. Descriptive statistics were used for analyses. MAIN RESULTS AND THE ROLE OF CHANCE: Of the 50 patients identified, 13 were CEP (26%), 8 were CSP (16%) and 29 were IEP (58%). Patients with a CSP had a higher parity (median = 3, P = 0.02) and number of prior Caesarean deliveries (mean = 2.1, P < 0.001). A total of 66% (23/35) of patients expressed a desire for future fertility prior to treatment and only 56% (28/50) of patients received reproductive counseling according to the electronic medical records. Among all non-tubal pregnancies, there were variations in the type and the order of treatments that patients received. LIMITATIONS REASONS FOR CAUTION: This study was performed in a tertiary referral center therefore the management strategy could have been influenced by the prior interventions and patient response. The descriptive retrospective design precluded any assumption of causation. WIDER IMPLICATIONS OF THE FINDINGS: The management for non-tubal pregnancies has wide variations. Reproductive counseling in this patient population is lacking. The findings highlight the need for the development of a treatment algorithm and a reproductive counseling protocol for each non-tubal pregnancy to better standardize treatment strategy. STUDY FUNDING/COMPETING INTERESTS: There was no funding for this study. The authors have no conflict of interest to report.

Obstetric Emergencies: Shoulder Dystocia and Postpartum Hemorrhage.

Shoulder dystocia and postpartum hemorrhage represent two of the most common emergencies faced in obstetric clinical practice, both requiring prompt recognition and management to avoid significant morbidity or mortality. Shoulder dystocia is an uncommon, unpredictable, and unpreventable obstetric emergency and can be managed with appropriate intervention. Postpartum hemorrhage occurs more commonly and carries significant risk of maternal morbidity. Institutional protocols and algorithms for the prevention and management of shoulder dystocia and postpartum hemorrhage have become mainstays for clinicians. The goal of this review is to summarize the diagnosis, incidence, risk factors, and management of shoulder dystocia and postpartum hemorrhage.

Carcinoma of the Bartholin Gland: A Review of 33 Cases.

OBJECTIVE: Primary carcinoma of the Bartholin gland is a rare malignancy that accounts for approximately 5% of vulvar carcinomas. The aim of the study was to compare the outcomes of women with primary Bartholin gland carcinoma (BGC) with those with non-Bartholin gland-related vulvar carcinoma. MATERIALS AND METHODS: A retrospective chart review of 429 patients with invasive vulvar carcinoma evaluated at a single institution between 1993 and 2011 was performed. Medical records were reviewed for demographic data, pathologic information, treatment type, and recurrence/outcome information. These variables were compared between patients with primary BGC and patients with non-Bartholin gland-related vulvar carcinoma. RESULTS: Thirty-three (7.7%) of the 429 patients with invasive vulvar carcinoma had primary carcinoma of the Bartholin gland. Twenty-nine patients (87.9%) had squamous cell histology and 4 patients (12.1%) had adenocarcinoma. When compared with non-Bartholin gland-related vulvar carcinoma, patients with primary BGC had a younger age at diagnosis (median, 57 vs 63 years; P = 0.045), had a higher rate of stage III/IV disease (60.6% vs 35.8%; P = 0.008), and were more likely to receive radiation therapy (78.8% vs 43.9%; P < 0.001). However, there were no significant differences between the 2 groups with regard to histologic subtype, lymphovascular space involvement, perineural invasion, positive margins, recurrence-free survival, or overall survival. CONCLUSIONS: Despite being diagnosed at a more advanced stage, patients with primary carcinoma of the Bartholin gland seem to have similar oncologic outcomes and survival rates to patients with non-Bartholin gland-related vulvar carcinoma.
