Reduction in Time from Admission to Operation of Women with Suspected Adnexal Torsion During the COVID-19 Pandemic.

BACKGROUND: Data regarding the management of adnexal torsion (AT) during the coronavirus disease 2019 (COVID-19) pandemic are scarce. OBJECTIVES: To study the effects of actions to limit the spread of COVID-19 on AT management. METHODS: We conducted a retrospective cohort study of all women who underwent laparoscopy for suspected AT between March 2011 and February 2021. We compared the COVID-19 pandemic period, (15 March 2020-2 August 2021, group A) to a parallel period (2019-2020, group B), and a 9-year period preceding the pandemic (March 2011-February 2020, group C). RESULTS: We performed 97 laparoscopies in group A, 82 in group B, and 635 in group C. The proportion of women presenting following in vitro fertilization treatment was lower (odds ratio [OR] 0.22, 95% confidence interval ]95%CI] (0.06-0.86), P < 0.023). Time from admission to decision to operate was shorter (2.7 vs. 3.9 hours, P = 0.028) in group A than group B. Time from admission to surgery was shorter (9.1 vs. 12.5 hours, P = 0.005) and the rate of surgically confirmed AT was lower (59 [60.8%] vs. 455 [71.7%], P = 0.030, OR 0.61, 95%CI 0.39-0.95) in group A than group C. Among surgically confirmed AT cases only, mean time from admission to decision was shorter in group A than group B (2.6 vs. 4.6 hours, P = 0.014). CONCLUSIONS: We identified differences in time from admission to clinical decision and from admission to surgery among women with suspected AT during the COVID-19 pandemic.

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.

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 of endometrial closure during cesarean section to the risk of developing uterine scar defect: a randomized control trial.

PURPOSE: The surgical technique for uterine closure following cesarean section influences the healing of the cesarean scar; however, there is still no consensus on the optimal technique regarding the closure of the endometrium layer. The aim of this study was to compare the effect of closure versus non-closure of the endometrium during cesarean section on the risk to develop uterine scar defect and associated symptoms. METHODS: A randomized prospective study was conducted of women undergoing first elective cesarean section at a single tertiary medical center. Exclusion criteria included previous uterine scar, preterm delivery and dysmorphic uterus. Women were randomized for endometrial layer closure versus non-closure. Six months following surgery, women were invited to the ambulatory gynecological clinic for follow-up visit. 2-D transvaginal ultrasound examination was performed to evaluate the cesarean scar characteristics. In addition, women were evaluated for symptoms that might be associated with uterine scar defect. Primary outcome was defined as the residual myometrial thickness (RMT) at the uterine cesarean scar. Data are presented as median and interquartile range. RESULTS: 130 women were recruited to the study, of them follow-up was achieved in 113 (86.9%). 61 (54%) vs. 52 (46%) of the women were included in the endometrial closure vs. non-closure groups, respectively. Groups were comparable for patient's demographic, clinical characteristics and follow-up time for postoperative evaluation. Median RMT was 5.3 (3.0-7.7) vs. 4.6 (3.0-6.5) mm for the endometrial closure and non-closure groups, respectively (p = 0.38). Substantially low RMT (< 2.5 mm) was measured in four (6.6%) women in the endometrial closure group and three (5.8%) of the women in the non-closure group (p = 0.86). All other uterine scar sonographic measurements, as well as dysmenorrhea, pelvic pain and intermenstrual bleeding rates were comparable between the groups. CONCLUSION: Closure versus non-closure of the endometrial layer during cesarean uterine incision repair has no significant difference in cesarean scar characteristics and symptom rates at 6 months follow-up.

Prophylactic salpingectomy with delayed oophorectomy as a two-staged alternative for primary prevention of ovarian cancer in BRCA1/2 mutation carriers: women's point of view.

OBJECTIVE: This study aimed to determine BRCA -mutation carrier women's interest and acceptability of participating in a study examining prophylactic salpingectomy with delayed oophorectomy (PSDO) as an alternative to the current recommendation for bilateral salpingo-oophorectomy for risk reduction. METHODS: This is a cross-sectional questionnaire-based study. All women visiting the high-risk clinics for hereditary breast and ovarian cancer in a single tertiary medical center were asked to complete a questionnaire concerning the two-stage approach from October 2018 to December 2019. Before completing the questionnaire, detailed explanation was given by a senior physician regarding the procedure, related background, possible risks, and benefits. RESULTS: The study population included 293 women, of whom 183 (62.4%) were BRCA1 mutation carriers, 97 (33.1%) were BRCA2 mutation carriers, and 13 (4.4%) had unknown familial mutation. Risk-reducing surgery was completed in 160 (55.17%) of the women. First-degree and second-degree family history was reported in 166 (57.24%) and 52 (17.9%) of the women, respectively. Among women surveyed, more than half of the women (n = 66 [51%]) who had yet to undergo risk-reducing surgery reported interest in having PSDO. Similarly, among those who had already received prophylactic surgery, 64 (40%) also considered PSDO to be an acceptable alternative. Multivariate logistic regression analysis found family history of related malignancies to be the only independent factor associated with reduced interest in a study of PSDO (odds ratio, 0.15 [95% confidence interval, 0.29-0.77]; P = 0.02). CONCLUSIONS: Overall, BRCA -mutation carrier women indicated interest in PSDO risk-reducing surgery, taking into consideration the potential additional risk. These findings suggest that a clinical study exploring the equivalence of PSDO as alternative treatment is feasible.

Proteomic signature for detection of high-grade ovarian cancer in germline BRCA mutation carriers.

No current screening methods for high-grade ovarian cancer (HGOC) guarantee effective early detection for high-risk women such as germline BRCA mutation carriers. Therefore, the standard-of-care remains risk-reducing salpingo-oophorectomy (RRSO) around age 40. Proximal liquid biopsy is a promising source of biomarkers, but sensitivity has not yet qualified for clinical implementation. We aimed to develop a proteomic assay based on proximal liquid biopsy, as a decision support tool for monitoring high-risk population. Ninety Israeli BRCA1 or BRCA2 mutation carriers were included in the training set (17 HGOC patients and 73 asymptomatic women), (BEDOCA trial; ClinicalTrials.gov Identifier: NCT03150121). The proteome of the microvesicle fraction of the samples was profiled by mass spectrometry and a classifier was developed using logistic regression. An independent cohort of 98 BRCA mutation carriers was used for validation. Safety information was collected for all women who opted for uterine lavage in a clinic setting. We present a 7-protein diagnostic signature, with AUC >0.97 and a negative predictive value (NPV) of 100% for detecting HGOC. The AUC of the biomarker in the independent validation set was >0.94 and the NPV >99%. The sampling procedure was clinically acceptable, with favorable pain scores and safety. We conclude that the acquisition of Müllerian tract proximal liquid biopsies in women at high-risk for HGOC and the application of the BRCA-specific diagnostic assay demonstrates high sensitivity, specificity, technical feasibility and safety. Similar classifier for an average-risk population is warranted.

Clinical features of isolated Fallopian tube torsion: evidence from a large series.

We aimed at studying isolated Fallopian tube torsion (IFTT) in a relatively large cohort of women and to evaluate different features of IFTT in comparison to a large cohort of women with non-IFTT adnexal torsion (NIAT). This was a retrospective cohort study. We included women with surgically confirmed ovarian and/or Fallopian tube torsion between March 2011 and June 2020. Fifty-four cases of IFTT were surgically confirmed during the study period and were compared to 422 surgically confirmed NIAT. The rate of controlled ovarian hyperstimulation treatments, current pregnancy, and vomiting was lower in the IFTT group compared with the NIAT group. Cervical tenderness and vaginal discharge were more common in the IFTT group. Oedematous and enlarged ovaries were less common in the IFTT group. In multivariate regression analysis, the following factors were independently associated with IFTT: (i) vaginal discharge [adjusted odds ratio (aOR) 95% CI 8.16, 1.98-33.55]; (ii) cervical motion tenderness (aOR 95% CI 2.71, 1.01-7.29); (iii) fertility treatments (aOR 95% CI 0.26, 0.70-0.77); (iv) previous abdominal surgery (aOR 95% CI 0.46, 0.22-0.96); (v) vomiting (aOR 95% CI 0.38, 0.19-0.76); and (vi) enlarged ovary (aOR 95% CI 0.34, 0.18-0.65). In conclusion, we have identified factors positively and negatively associated with IFTT in a large cohort of women with adnexal torsion.

Pediatric and adolescent females are at higher risk of adnexal torsion recurrence-A large-scale retrospective study.

AIM: Recurrence of adnexal torsion (rAT) is reported mainly in small series. Normal and small appearing ovaries are associated with an increased risk for rAT. Nevertheless, updated data of larger cohorts is lacking. We aimed to investigate the predictors for rAT in a cohort of women who had surgical intervention for primary adnexal torsion (pAT). METHODS: A retrospective case-control study from a single institution between 2011 and 2020. Women with a primary occurrence of surgically proven adnexal torsion were included. We compared those who had experienced rAT to those who had not. Univariate and multivariate analysis were performed to study independent predictors for rAT. RESULTS: Overall, 358 women were included. Of those, 35 (9.8%) had a rAT. Women who experienced rAT were younger (mean age 26 vs. 30 years, p = 0.01). Women experiencing rAT had smaller mean ovarian cyst diameter in the pAT episode (42 vs. 59 mm. p < 0.001). Performance of laparoscopic detorsion was only associated with rAT (odds ration [OR] 95% confidence interval [CI] 2.13 [1.02-4.42], p = 0.03), while the performance of additional cystectomy was negatively associated with rAT (OR 95% CI 0.10 [0.01-0.79], p = 0.006). Multivariate analysis demonstrated that age ≤15 and smaller cyst diameter at pAT were independently associated with the risk for rAT (aOR 95% CI 5.0 [1.09-23.2] and 1.47 [1.08-2.0], for every 10 mm decrease in cyst diameter, respectively). CONCLUSIONS: Adolescents and pediatric females and women with smaller ovarian cysts at pAT are at higher risk for future recurrence of adnexal torsion.

Office Operative Hysteroscopy for the Management of Retained Products of Conception.

The aim of this study was to compare office to conventional operative hysteroscopy for the treatment of retained products of conception (RPOC). This retrospective cohort study included all women who underwent hysteroscopy due to RPOC between January 2018 and December 2019, in a single tertiary medical care center. Exclusion criteria for hysteroscopy included the following: (1) proximity to delivery (up to 3 weeks); (2) hemodynamic instability; (3) active massive bleeding; and (4) genital tract infection. See-and-treat hysteroscopy (study group) outcomes were compared to operative hysteroscopy (controls). Data were collected from women's medical records. Primary outcome was defined as successful removal of all suspected RPOC with no need for additional intervention. Data are presented as median and interquartile range. During the study period, 222 women underwent hysteroscopy due to RPOC. Of them, 138 (62%) and 84 (38%) underwent see-and-treat and operative hysteroscopy, respectively. Symptomatic women were more commonly referred to operative hysteroscopy (60 (71%) vs. 54 (39%); p = 0.001). Maximal diameter of the suspected finding was smaller both by ultrasound examination (13 (10-18) vs. 18 (13-32) mm; p = 0.001) and by surgeon estimation during diagnostic hysteroscopy (12 (8-20) vs. 20 (14-30) mm; p = 0.001), in the see-and-treat compared to the operative hysteroscopy group, respectively. While comparing success rate between groups, no difference was observed. Sub-analysis by the maximal diameter of RPOC findings revealed that see-and-treat success rate is reduced as the RPOC is larger. Success rate was high and comparable to operative hysteroscopy for findings ≤ 2 cm (102/117 (87%) vs. 49/54 (91%); p = 0.79). Nevertheless, for RPOC > 2 cm, success was significantly more frequent in the operative hysteroscopy group (28/30 (93%) vs. 9/16 (57%); p = 0.002). This finding was supported by logistic regression analysis that found maximal diameter of RPOC as the only parameter associated with success rate (B = 0.96; p = 0.03). Office operative hysteroscopy is a feasible treatment option for the removal of RPOC when maximal diameter is taken under consideration due to its association to success rate.Clinical trial registration: The study protocol was approved by the "Sheba Medical Center" Review Board (ID 5200-18 SMC) on June 24, 2018.

A clinical prediction model for adnexal torsion in pediatric and adolescent population.

PURPOSE: To describe the clinical characteristics of children and adolescents that underwent diagnostic laparoscopy for suspected adnexal torsion (AT), and to develop a prediction model for preoperative detection of AT among young women. METHODS: A retrospective cohort study. We included all girls ≤18 years old with clinically suspected AT who underwent a diagnostic laparoscopy between 3/2011 and 6/2020. We compared patients with AT to those without AT and constructed a prediction model. RESULTS: Overall, 120 children and adolescents with suspected AT were included in the study. Of those, AT was identified in 83 (69.2%). In a multivariate analysis, the following risk factors were independently associated with AT and included in the prediction model: absence of right lower quadrant tenderness upon examination [adjusted odds ratio (aOR) (95% Confidence interval (CI)) 3.23 (1.23-8.47), p = 0.017], platelets level >240 K [aOR (95% CI) 3.15 (1.19-8.36), p = 0.021], and neutrophils level >5.4 [aOR (95% CI) 2.71 (1.02-7.52), p = 0.046]. The rate of AT was 12.5% in cases without risk factors for AT, 56.7% with one, 68.8% with two, and 94.1% with three risk factors present, respectively. CONCLUSIONS: We have identified preoperative indicators independently associated with surgically confirmed AT in a large cohort of young women. Level of evidence- III.

The Influence of Cesarean Delivery on Ovarian Reserve: a Prospective Cohort Study.

To assess the association between cesarean delivery and ovarian reserve, as compared to vaginal delivery. A prospective case control study conducted at a single tertiary medical center between June 2018 and June 2019. Study population included women with singleton pregnancy that underwent first cesarean delivery that were compared to women undergoing normal vaginal delivery. Women with low ovarian reserve, endometriosis, previous pelvic surgery, chronic maternal disease, and active labor were excluded. Ovarian reserve was estimated by Anti-Mullerian hormone (AMH) levels that was determined twice for each participant: up to a week before and 3 months after delivery. Primary outcome was defined as the delta in AMH levels. Data were analyzed by non-parametric tests. During the study period, 135 women were enrolled, of them 63 (47%) underwent cesarean delivery and 72 (53%) had vaginal delivery. Women in the cesarean delivery group were older (34 (31-38) vs. 32 (29-35); p = 0.001); nevertheless, AMH levels measured before delivery were comparable between the two groups (0.92 (0.51-1.79) vs. 0.95 (0.51-1.79) pg/mL; p = 0.42). AMH levels measured after delivery were more than doubled in the study and control groups (2.15 (1.24-3.05) vs. 2.62 (1.05-5.09); p = 0.50), and delta AMH levels were also found comparable (1.25 (0.61-2.22) vs. 1.59 (0.63-3.41), respectively; p = 0.43). Linear regression analysis including age, mode of delivery, gestational age at delivery, and delta hemoglobin levels revealed that only maternal age was significantly associated with delta in AMH levels (B = - 0.09, p = 0.04). Cesarean delivery does not decrease ovarian reserve as estimated by AMH.

Placenta accreta spectrum in subsequent pregnancy following myomectomy.

PURPOSE: To compare the prevalence of placental abnormalities in pregnancy following different modes of operative myomectomy. METHODS: A retrospective cohort study, including all women after myomectomy that gave birth in a single tertiary care center from February 2011 to January 2019. Data was collected from the patients' medical files and completed by telephone questionnaire. Patients were stratified to 3 groups, according to the mode of operative myomectomy (laparotomy, laparoscopy, hysteroscopy). Groups were compared for women demographics, fibroid's characteristics, operative management, post-operative placental evaluation and delivery characteristics. Primary outcome was defined as the need for any intervention for placental separation during the third phase of the delivery. RESULTS: Two hundred forty one women met inclusion criteria. Complete follow-up was achieved in 199 (82.57%) women, of whom 82, 89, and 28 underwent laparoscopic, laparotomy and hysteroscopic myomectomy, respectively. There were no in-between groups differences in women's age, BMI, and gravidity. Disruption of the endometrial cavity during laparoscopy and laparotomy was reported in 3 (3.6%) and 7 (7.8%) cases, respectively (p = .21). During the subsequent pregnancy following myomectomy, placenta accreta spectrum disorder was suspected in only one woman in each of the study groups (p = .63). Placenta previa was low and comparable between groups. Vaginal delivery rate was significantly higher in the hysteroscopy group, as compared to the laparoscopy or the laparotomy groups [11 (36.3%) vs. 5 (6.1%) vs. 4 (4.5%); p = .001], with significantly lower need for manual lysis of the placenta [11(39.0%) vs. 51 (62.1%) vs. 62 (69.7%); p = .01] and further interventions for blood loss control. CONCLUSIONS: Subsequent pregnancy following surgical myomectomy was not found to be associated with higher prevalence placental abnormality. Furthermore, other than manual lysis, the different modes of myomectomy did not necessitate any further intervention for complications associated with abnormal placentation requiring intervention. KEY MESSAGE: Subsequent pregnancy following surgical myomectomy is not associated with higher prevalence of placental abnormality.

Cesarean delivery with and without uterine artery embolization for the management of placenta accreta spectrum disorder-A comparative study.

INTRODUCTION: The aim of this study is to compare immediate and long-term obstetrical outcomes of patients who underwent cesarean delivery with and without uterine artery embolization (UAE) for the management of placenta accreta spectrum disorder. MATERIAL AND METHODS: A retrospective case control study including all pregnant women admitted to a single tertiary medical center between December 2001 and May 2018 with a diagnosis of placenta accreta spectrum disorder, who underwent cesarean delivery with and without UAE. Groups were compared for maternal characteristics, operative management, postoperative complication rate and long-term outcomes. Follow up on future obstetrical outcomes was conducted via telephone questionnaire. Non-parametric statistics were used. RESULTS: During the study period, 272 women met the inclusion criteria: 64 (23.53%) and 208 (76.47%) underwent preservative cesarean section with and without UAE, respectively. UAE procedure was associated with a longer operative time (82.5 [68-110] vs 50.5 [39-77] minutes; P = .001), and higher blood loss (2000 (1500-3000) vs 1000 (600-2000) mL; P = .001). Hysterectomy rate was comparable between the groups (9 [14%] vs 35 [16.82%]; P = .88); however, multivariate logistic regression analysis found UAE to be an independent factor associated with lower hysterectomy rate (P = .02). Postoperative complications were more frequent in the UAE group. Follow up was achieved in 29 (59.18%) and 72 (51.79%) of the women with and without UAE, respectively (P = .36). No differences were found in rate of abortions, pregnancy and deliveries between the groups. CONCLUSIONS: Cesarean delivery using UAE in placenta accreta spectrum disorder is associated with a higher rate of operative and postoperative complications. Nevertheless, in cases of severe adherence of the placenta, embolization reduces the need for hysterectomy, allowing future fertility.

Long-term outcome of MR-guided focused ultrasound treatment and laparoscopic myomectomy for symptomatic uterine fibroid tumors.

BACKGROUND: Fibroid tumors are the most common benign tumors in women of reproductive age. Treatment is usually indicated for those who are symptomatic, with different techniques being used. OBJECTIVE: The purpose of this study was to compare the long-term outcome of laparoscopic myomectomy with magnetic resonance-guided focused ultrasound for symptomatic uterine fibroid tumors. STUDY DESIGN: A cohort study was conducted on all patients with symptomatic uterine fibroid tumors who were admitted to a single tertiary care center and treated operatively with laparoscopic myomectomy or treated conservatively with magnetic resonance-guided focused ultrasound from January 2012 until January 2017. Assessment for further interventions and sustained fibroid-associated symptoms was performed, with the use of the Uterine Fibroid Symptom and Quality of Life symptom severity score. RESULTS: One hundred fifty-four women met the inclusion criteria. Complete follow-up evaluation was achieved for 64 women who underwent laparoscopic myomectomy and for 68 women who were treated by magnetic resonance-guided focused ultrasound. Follow-up time was similar for the 2 groups (median, 31 months [interquartile range, 17-51 months] vs 36 months [interquartile range, 24-41]; P=.95). The rate of additional interventions was 5 (7.8%) and 9 (13.2%), respectively (P=0.312). Similarly, the Uterine Fibroid Symptom and Quality of Life symptom severity score questionnaire score at follow-up interviews revealed comparable median scores of 17 (interquartile range, 12-21) vs 17 (interquartile range, 13-22) for laparoscopic myomectomy and magnetic resonance-guided focused ultrasound, respectively (P=.439). Analysis of each of the symptoms separately (bleeding, changes in menstruation, abdominal pain, bladder activity, nocturia, fatigue) did not change these findings, nor did a multivariate analysis. CONCLUSION: Satisfaction with long-term outcome and rate of reinterventions after magnetic resonance-guided focused ultrasound treatment or laparoscopic myomectomy for uterine fibroid tumors was comparable. Further larger randomized trials are needed to confirm these findings.

Outcome of magnetic resonance-Guided focused ultrasound surgery (MRgFUS) for FIGO class 1 fibroids.

OBJECTIVE: Intracavitary uterine fibroids and fibroids that distort the uterine cavity are associated with excessive vaginal bleeding and infertility. While intracavitary fibroids smaller than 4 cm are usually treated safely by operative hysteroscopy, larger fibroids may require multiple surgeries or more extensive surgery with possible damage to the integrity of the uterine wall. Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is a noninvasive approach for treating uterine fibroids, mainly the intramural type. We present the outcome of MRgFUS treatment for intracavitary fibroids (FIGO class 1) in cases that could not be treated by hysteroscopy due to either fibroid size or patient refusal. (Canadian Task Force II-1). STUDY DESIGN: A retrospective cohort study from a single tertiary referral center. A total of 68 patients were treated by MRgFUS for symptomatic uterine fibroids from January 2013 to December 2016. Six of them had FIGO class 1 fibroids. Adverse effects and short- and long-term outcomes (quality of life issues and need for additional surgical intervention) were assessed during ambulatory clinic visits and by phone interviews. RESULTS: The mean ±â€¯SD fibroid volume on MRI screening was 86.3 ±â€¯60.9 cm3. Six of those patients underwent the procedure (mean age 40.5 ±â€¯5.6 years, range 33-48). The follow-up duration was 24.1 ±â€¯12.0 months. Four patients were not interested in future fertility and did not undergo additional treatment, while the two who planned to conceive underwent another surgical intervention (one underwent operative hysteroscopy after reduction of fibroid size and the other underwent laparoscopic myomectomy). CONCLUSION: This preliminary study shows that MRgFUS can be a feasible treatment option for FIGO class 1 uterine fibroids. Shrinkage of fibroids by MRgFUS can obviate or facilitate subsequent surgical intervention in selected cases.
