Abstract Surgery continues to be a mainstay of treatment for patients with symptomatic fibroids. Hysterectomy is an option for those desiring definitive treatment and myomectomy is preferred for those that have not yet completed childbearing or wish to retain their uterus. While open laparotomy remains a viable approach to both hysterectomy and myomectomy, minimally invasive techniques for the surgical management of symptomatic fibroids are preferred options for many due to improved patient outcomes. These include hysteroscopic myomectomy, laparoscopic and robotically assisted myomectomy, and vaginal, laparoscopic, and robotically assisted hysterectomy. Patients have a faster recovery and less postoperative pain compared to a laparotomic approach. More recently, uterine‐sparing outpatient modalities such as ultrasound‐guided radiofrequency ablation and high‐intensity focused ultrasound have emerged as promising alternatives for selected patients. Benefits include clinically significant reduction in fibroid size and menstrual bleeding with small or no abdominal incisions and an expedited convalescence. This article reviews preoperative evaluation and imaging for fibroids, as well as the techniques, approach, indications, patient selection, procedural management, and surgical and fertility outcomes for each surgical and procedural management of uterine fibroids.

History A 30-year-old female patient with a history of infertility and no pregnancy presented to the gynecologic endometriosis clinic for follow-up 1 month after oocyte retrieval, to be evaluated for pelvic optimization before potential embryo transfer, with worsening dysmenorrhea, dyspareunia, and overall pelvic pain. Eleven years prior, the patient had undergone left ovarian cystectomy for treatment of endometrioma, as well as excision of deep infiltrating endometriosis. The oocyte retrieval procedure, where more than 30 eggs were retrieved, was complicated by ovarian hyperstimulation syndrome and intraperitoneal bleeding, which necessitated admission to the intensive care unit (ICU) for 3 days. Following discharge from the ICU, the patient experienced occasional on-and-off pressure of the urinary bladder and persistent aching pelvic pain. At the 1-month follow-up appointment, the patient’s vital signs were assessed (blood pressure, 142/94 mm Hg; pulse rate, 95 per minute; temperature, 96.8 °F [36 °C]). Routine blood investigations, including white blood cell count, were within normal limits. Physical examination showed the abdomen was soft but there was mild pelvic tenderness. The serum β–human chorionic gonadotropin test result was negative for pregnancy, and urinalysis testing showed no leukocyte esterase or nitrites. MRI of the pelvis was performed to evaluate the worsening pain.

ABSTRACT Background Studies have found that women with endometriosis have a higher risk of female sexual dysfunction (FSD). Aim To evaluate the relationship between self-reported endometriosis and FSD utilizing validated surveys. Methods A cross-sectional analysis was conducted among sexually active women aged 18–90 who presented to 3 Mayo Clinic sites from 2015 to 2021. FSD was determined utilizing a combined endpoint of Female Sexual Function Index score ≤ 26.55 and Female Sexual Distress Scale-Revised score ≥ 11. Associations between history of endometriosis and FSD were evaluated by fitting 3 multivariable logistic models and were stratified by menopause status. In the first model, the association was adjusted for age, BMI, race/ethnicity, marital status, and education. The second model adjusted for the variables in Model 1 and hormone therapy, hormonal contraceptive use, self-reported history of abuse within the last year, and co-morbidities including the history of diabetes, heart disease, hypertension, osteoporosis, and stroke. The third model adjusted for the variables in Model 1, Model 2, and anxiety, depression, relationship satisfaction, and SSRI/SNRI use. Outcomes The outcomes included self-reported endometriosis and female sexual dysfunction determined utilizing a combined endpoint of Female Sexual Function Index score ≤ 26.55 and Female Sexual Distress Scale-Revised score ≥ 11. Results Of 7118 patients (mean age 51.3), 92.2% were white, 78.4% were peri- or postmenopausal, 8.7% reported endometriosis history, and 57.2% met the criteria for FSD. Women with endometriosis were more likely to be overweight or obese, be smokers, have had a history of heart disease and osteoporosis, have had anxiety and depressed mood, have had a hysterectomy and bilateral salpingo-oophorectomy, and have used hormone therapy. Compared to those without endometriosis, women with endometriosis were significantly more likely to have FSD only among premenopausal women (74.2% vs 57.4%). Similarly, in multivariable analysis the relationship was only seen for premenopausal women in all 3 models (Model 1: OR 2.74 (95% CI 1.43–5.27); Model 2: OR 2.55 (95% CI 1.30–5.04); Model 3: OR 2.30 (95% CI 1.13–4.68)). Clinical Implications These findings highlight the opportunity for healthcare practitioners to evaluate sexual function in premenopausal women with endometriosis. For peri and postmenopausal women with endometriosis, the risk of FSD was lower than for premenopausal women with endometriosis. Strengths and Limitations This study analyzed the association between endometriosis and FSD in women by menopause status using validated tools that included a measure of distress associated with sexual dysfunction. Limitations include its cross-sectional design which does not allow for determination of the direction of this association. Conclusion The risk for FSD associated with endometriosis depends on menopause status. Endometriosis increased the odds of FSD only in premenopausal women.

Abstract Context Enhanced Recovery After Surgery (ERAS) is a multimodal protocol aimed to improve quality of postoperative recovery, minimize complications, and optimize overall self-regulation. Preoperative gabapentin decreases postoperative pain but can be associated with prolonged postoperative somnolence and respiratory depression risk. Although it is known that gabapentin affects the postoperative course, it is unclear if the timing of preoperative administration affects this finding. Objectives This study aims to assess the optimal preoperative timing for gabapentin administration in patients undergoing gynecologic surgery to minimize postoperative somnolence risk. Methods A retrospective cohort study evaluated patients who underwent major gynecologic surgery and received preoperative gabapentin. Patients were grouped based on timing from gabapentin administration to surgical incision (<4 h group vs. ≥4 h group). Preoperative, intraoperative, and postoperative data were abstracted and compared. Univariate associations between the timing of gabapentin administration and the patient and surgical characteristics and outcomes were tested utilizing two-sample equal-variance t-tests, linear model ANOVA, or Fisher’s exact tests. Associations between the timing of gabapentin administration and the time until the Richmond Agitation Sedation Scale (RASS) score of 0 were modeled utilizing linear regression, adjusted for age, initial postoperative anesthesia care unit (PACU), RASS score, and postoperative narcotics. Results Each group contained 127 patients. Demographics were similar except for age (<4 h group mean=44.2 years; ≥4 h group mean=40.5 years; p=0.021), chronic pain (<4 h group=17.6%; ≥4 h group=43.3%; p<0.001), and surgical indication (<4 h group=pelvic pain [29.1%]; ≥4 h group=pelvic pain [51.2%]; p=0.007). The <4 h group had a similar postoperative narcotic administration (<4 h group mean morphine milligram equivalents [MME]=3.667; ≥4 h group mean MME=4.833; p=0.185). The minutes from surgical closure until the patient received a RASS score of 0 and initial PACU pain score (Visual Analogue Scale [VAS]) were similar. The initial PACU oxygen administration volume, hours from surgical closure until the patient transitioned to room air, and initial PACU respiratory rate were similar. The PACU duration, admission secondary to somnolence, and initial PACU Glasgow Coma Scale (GCS) score showed no difference. Postoperative nausea/vomiting was decreased in the ≥4 h group (<4 h group=24.4%; ≥4 h group=13.4%; p-value=0.036), and urinary retention (<4 h group=14.2%; ≥4 h group=5.5%; p-value=0.033) was decreased in the ≥4 h group. Conclusions The timing of gabapentin administration less than or more than 4 h preoperatively in patients ≥18 years does not significantly affect postoperative somnolence or respiratory depression. Further, it does not have a significant effect on GCS scores or VAS scores.

ObjectivesThe study aim was to evaluate the diagnostic performance of the uterine sliding sign in predicting deeply infiltrating endometriosis in the setting of non‐physician sonographers performing but not interpreting the maneuver. The impact of uterine sliding sign has not been previously demonstrated in this practice setting.MethodsPhysicians' remote interpretations of transvaginal ultrasound examinations in 2016, before uterine sliding sign, were compared to examinations in 2019 after addition of uterine sliding sign to determine the diagnostic rates. Surgical and histopathological results were reviewed to determine sensitivity and specificity of the respective exam techniques.ResultsTwo hundred eighty‐five transvaginal ultrasounds were performed in 2016 and 390 sliding sign ultrasounds in 2019. The number of deeply infiltrating endometriosis cases identified increased significantly from 2% to 6% during the study period (chi‐square, Fisher's exact test p = .012). The sensitivity and specificity of routine pelvic sonography for detecting deeply infiltrating endometriosis improved from 36%/94% to 68%/98%.ConclusionsUterine sliding sign videos should be included in the standard sonographic protocol for patients presenting with chronic pelvic pain, endometriosis history, or sonographic evidence of endometriosis in the setting of physicians interpreting sonographic images obtained by non‐physicians.
