Long-Term Risk of Reintervention After Surgical Leiomyoma Treatment in an Integrated Health Care System.

OBJECTIVE: To compare long-term risk of reintervention across four uterus-preserving surgical treatments for leiomyomas and to assess effect modification by sociodemographic factors in a prospective cohort study in an integrated health care delivery system. METHODS: We studied a cohort of 10,324 patients aged 18-50 (19.9% Asian, 21.2% Black, 21.3% Hispanic, 32.5% White, 5.2% additional races and ethnicities) who had a first uterus-preserving procedure (abdominal, laparoscopic, or vaginal myomectomy [referred to as myomectomy]; hysteroscopic myomectomy; endometrial ablation; uterine artery embolization) after leiomyoma diagnosis in the 2009-2021 electronic health records of Kaiser Permanente Northern California. We followed up patients until reintervention (second uterus-preserving procedure or hysterectomy) or censoring. We used a Kaplan-Meier estimator to calculate the cumulative incidence of reintervention and Cox regression models to estimate hazard ratios and 95% CIs comparing rates of reintervention across procedures, adjusting for age, parity, race and ethnicity, body mass index (BMI), Neighborhood Deprivation Index, and year. We also assessed effect modification by demographic characteristics. RESULTS: Median follow-up was 3.8 years (interquartile range 1.8-7.4 years). Index procedures were 18.0% (1,857) hysteroscopic myomectomies, 16.2% (1,669) uterine artery embolizations, 21.4% (2,211) endometrial ablations, and 44.4% (4,587) myomectomies. Accounting for censoring, the 7-year reintervention risk was 20.6% for myomectomy, 26.0% for uterine artery embolization, 35.5% for endometrial ablation, and 37.0% for hysteroscopic myomectomy; 63.2% of reinterventions were hysterectomies. Within each procedure type, reintervention rates did not vary by BMI, race and ethnicity, or Neighborhood Deprivation Index. However, rates of reintervention after uterine artery embolization, endometrial ablation, and hysteroscopic myomectomy decreased with age, and reintervention rates for hysteroscopic myomectomy were higher for parous than nulliparous patients. CONCLUSION: Long-term reintervention risks for uterine artery embolization, endometrial ablation, and hysteroscopic myomectomy are greater than for myomectomy, with potential variation by patient age and parity but not BMI, race and ethnicity, or Neighborhood Deprivation Index.

The Median Effective Dose of One Intravenous Bolus of Oxycodone for Postoperative Analgesia After Myomectomy and Hysterectomy With Local Ropivacaine Wound Infiltration: An Up-Down Dose-Finding Study.

BACKGROUND: Oxycodone has been shown to be an effective analgesic for early postoperative analgesia, especially for abdominal operations associated with severe visceral pain. However, the dose needed varies depending on the operation and application of multimodal analgesia, such as local ropivacaine wound infiltration. Therefore, we conducted this study to estimate the median effective dose (ED50) of oxycodone that provides analgesia for hysterectomy and myomectomy with local ropivacaine wound infiltration. METHODS: In this dose-finding study, the ED50 of oxycodone for postoperative analgesia was estimated separately for laparoscopic hysterectomy, transabdominal hysterectomy, laparoscopic myomectomy, and transabdominal myomectomy. We used the sequential allocation designed by Dixon. Trials were conducted simultaneously in the 4 surgical type groups. A predefined dose of oxycodone was injected 30 minutes before the end of the operation with an initial dose of 0.1 mg/kg. A series of trials were performed following the rule of a relative 10% increase in dose after inadequate analgesia and a relative 10% decrease in dose after adequate analgesia. The study was conducted until the collection of 7 crossover points was achieved. Local ropivacaine wound infiltration was administered during abdominal stitching. The mean blood pressure (MBP) and heart rate (HR) were analyzed to assess the hemodynamic changes associated with oxycodone administration. RESULTS: A total of 113 patients were included in the estimation of ED50: 28 each in the laparoscopic hysterectomy group and transabdominal myomectomy group, 27 in the transabdominal hysterectomy group, and 30 in the laparoscopic myomectomy group. The estimated oxycodone ED50 (95% confidence interval [CI]) after laparoscopic hysterectomy, transabdominal hysterectomy, laparoscopic myomectomy, and transabdominal myomectomy was 0.060 mg/kg (0.053-0.068), 0.079 mg/kg (0.072-0.086), 0.060 mg/kg (0.051-0.071), and 0.092 mg/kg (0.086-0.098), respectively, for postoperative analgesia with local ropivacaine wound infiltration. The ED50 of oxycodone was different between laparoscopic surgeries and transabdominal surgeries (P < .001). The MBP and HR before and after oxycodone injection were different, regardless of surgical type. CONCLUSIONS: The oxycodone ED50 for postoperative analgesia was lower for laparoscopic hysterectomy (0.060 mg/kg) and laparoscopic myomectomy (0.060 mg/kg) than for transabdominal hysterectomy (0.079 mg/kg) and transabdominal myomectomy (0.092 mg/kg) when combined with local ropivacaine wound infiltration. A single intravenous injection of oxycodone is associated with an acceptable decrease in MBP and HR within a short time.

Radiofrequency Thermal Ablation for Uterine Myomas: Long-term Clinical Outcomes and Reinterventions.

STUDY OBJECTIVE: To assess the long-term efficacy and rate of reintervention after ultrasound-guided radiofrequency thermal ablation (RFA) for uterine myomas. DESIGN: A retrospective follow-up, cohort study (Canadian Task Force classification II-2). SETTING: University hospitals and private clinics. PATIENTS: Between November 1, 2007, and February 26, 2010, 66 consecutive women underwent ultrasound-guided RFA. INTERVENTIONS: Patients underwent abdominal or vaginal ultrasound-guided RFA and were contacted for a long-term follow-up to complete the Uterine Fibroid Symptom and Quality of Life Score (UFS-QOL) questionnaire and optional ultrasound and examination. MEASUREMENTS AND MAIN RESULTS: Sixty-six consecutive patients (mean age 45 ± 7 years) with type 2 to 5 symptomatic myomas per the International Federation of Gynecology and Obstetrics (median size = 122.5 cm3 [range, 24-675]) were included. Forty of 62 patients recruited for follow-up underwent no/minor hysteroscopic reinterventions; 35 patients from this group completed the UFS-QOL questionnaire and showed sustained and improved symptom severity scores (100-point scale) from baseline (57.2 ± 16.6) to long-term follow-up (23.8 ± 20.8, p < .001). Twenty-two patients (35%) had major reinterventions (15 hysterectomies and 7 myomectomies). Six of the 22 patients underwent major reinterventions for reasons other than myoma-related complaints. The estimated major reintervention rate because of myoma-related symptoms determined by the Kaplan-Meier method was 13.5% (95% confidence interval [CI], 7%-25%) after 2 years and 29.1% (95% CI, 19%-43%) after 5 years. Women ≥45 years of age had a major reintervention rate of 12% (95% CI, 5%-26%) after 2 years and 19% (95% CI, 10%-35%) after 5 years, and women <45 years had a major reintervention rate of 35.0% (95% CI, 19%-60%) and 73.8% (95% CI, 52%-92%) after 2 and 5 years, respectively. Fewer major reinterventions occurred in women with only 1 RFA-treated myoma (volume ≤180 cm3, diameter <7 cm) than women with more than 1 RFA-treated myoma (>180 cm3, p < .01). The Kaplan-Meier estimates for reintervention in women with only 1 RFA-treated myoma with a volume ≤180 cm3 were 13% (95% CI, 6-28%) and 26% (95% CI, 14%-45%) after 2 and 5 years, respectively. No patients with morphologic myoma characteristics underwent reinterventions. CONCLUSION: Ultrasound-guided RFA for uterine myomas is an alternative treatment option especially for women ≥45 years of age with only 1 myoma (volume ≤180 cm3) and warrants further evaluation.

Minilaparotomy Versus Laparoscopic Myomectomy After Cessation of Power Morcellation: Rate of Wound Complications.

STUDY OBJECTIVE: After the US Food and Drug Administration statement warning against electronic morcellation devices, gynecologic surgeons are performing laparoscopic and robotic myomectomies with minilaparotomy incisions for tissue morcellation and removal. No data exist that focus on the superficial wound complications as a result of these larger incisions. The objective of this study is to compare the rate of wound complications for myomectomy via minilaparotomy versus laparoscopic or robotic myomectomy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-2). SETTING: Kaiser Permanente Northern California, a large integrated healthcare delivery system. PATIENTS: Women > 18 years of age who underwent a myomectomy from either complete laparoscopic or robotic approach (LR) were compared with minilaparotomy myomectomy (MM), comprising complete minilaparotomy (ML) and laparoscopic or robotic assisted by a minilaparotomy for morcellation purposes only (LRM) from January 2011 through December 2014. INTERVENTION: Myomectomy via LR, complete ML, and LRM. MEASUREMENTS AND MAIN RESULTS: Medical records were reviewed for outcomes of interest, including superficial wound complications and surgical and demographic data. After exclusion criteria were met, 405 cases were included in the study; 270 cases were classified as MM, which included ML (n = 224), or LRM (n = 46). One hundred thirty-five cases were classified as LR. Parametric and nonparametric analyses were used to compare the 2 groups. There was no significant difference between the groups insofar as patient morbidity, including the primary outcome of wound complications and other postoperative complications; emergency visits; or readmissions. There were 2 (1.5%) wound complications in the LR group and 7 (2.6%) in the MM group (p = .72). Similarly, there were no significant differences in the subcategories of wound complications, including cellulitis, seroma, hematoma, skin separation, wound infection, or postprocedure wound complication. The distribution of estimated blood loss was significantly different between LR and MM groups with an interquartile range of 50 to 150 mL in the LR group versus 50 to 300 mL in the MM group (p < .01). The MM group experienced a shorter procedure time with a median procedure time of 125 minutes compared with 169.5 minutes in LR surgeries (p < .01). The LR group demonstrated a significantly shorter median length of hospital stay (LR 5.0 hours vs MM 23 hours; p < .01). CONCLUSION: Compared with MM, LR is associated with a shorter length of hospital stay and longer operating time but no reduction in wound complication or other patient morbidity.

Magnetic resonance-guided focused ultrasound myomectomy: safety, efficacy, subsequent fertility and quality-of-life improvements, a systematic review.

We performed a systematic review about studies reporting data of myomectomy performed by magnetic resonance-guided focused ultrasound (MRgFUS) technique in order to define its safety, feasibility, indications, complications, and impact on uterine fibroid symptom and health-related quality of life (UFS-QOL) and fertility. Outcomes were considered according to fibroids shrinkage, nonperfused volume (NPV), NPV ratio, and uterine fibroid symptoms assessed with UFS-QOL questionnaire (baseline 3, 4, 6, and 12 months). We analyzed 38 eligible studies reporting outcomes about 2500 patients (mean age 43.67 years). The MRgFUS results a safe, efficient, and cost-effective minimal invasive technique for treatment of uterine fibroids. Increasing experience, device improvements, and availability for a larger number of patients are enhancing the outcomes, while the obstetrical ones should be more extensively explored. The MRgFUS could be considered as a minimal invasive alternative to traditional surgical or radiological procedures for the treatment of symptomatic uterine myomas improving both QOL and subsequent fertility.
