Abstract Uterine fibroids (leiomyomas) and adenomyosis are among the most common benign gynecological conditions affecting women of reproductive age. These disorders are frequently associated with abnormal uterine bleeding, pelvic pain, pressure symptoms on adjacent pelvic organs, and potential infertility. The incidence of fibroids increases as women enter their third and fourth decades of life. In parallel, recent trends in delayed childbearing have further emphasized the need for fertility‐preserving treatment options. Notably, fibroids have a higher prevalence in African‐American women, highlighting a significant disparity in health needs compared to white women. Historically, hysterectomy and myomectomy were considered definitive treatments. However, these procedures carry inherent surgical risks, longer recovery periods, and, in the case of hysterectomy, a complete loss of reproductive potential. Consequently, there is increasing demand for uterus‐sparing, minimally invasive alternatives that provide effective symptom control with lower morbidity and preservation of fertility. Among the evolving treatment options, three image‐guided, minimally invasive therapies have gained particular attention: Uterine Artery Embolization (UAE), Radiofrequency Ablation (RFA), and High‐Intensity Focused Ultrasound (HIFU). Uterine Artery Embolization (UAE), also known as uterine fibroid embolization (UFE), is a well‐established endovascular procedure in which embolic agents are introduced via catheterization of the uterine arteries, inducing ischemia and infarction of fibroids. Performed under conscious sedation or regional anesthesia, UAE has demonstrated significant reductions in fibroid volume and symptom relief in over 80% of appropriately selected patients. All image‐guided techniques are especially beneficial for women who desire uterine preservation, have contraindications to surgery, or wish to avoid major operative interventions. In comparison with UAE, Radiofrequency Ablation (RFA) uses targeted thermal energy to induce coagulative necrosis within fibroid tissue. This approach can be delivered via laparoscopic, transcervical, or transvaginal routes, depending on the platform. The Sonata® System integrates intrauterine ultrasound guidance with energy delivery, enabling precise fibroid targeting with minimal myometrial damage. RFA is associated with shorter recovery and less intraoperative blood loss, though it is more suitable for smaller or fewer fibroids and may be less ideal for extensive disease. Together, these advancements reflect a paradigm shift in fibroid management—driven by demographic trends, racial disparities, patient preferences, and technological innovations—toward evidence‐based, uterus‐preserving therapies tailored to individual patient needs. This article discusses details of each technique including the procedure, benefits and complications and also the impact on particular situations such as pregnancy. Some key points common to each technique are also mentioned.

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.
