Transcervical fibroid ablation with the Sonata™ system for treatment of submucous and large uterine fibroids

Outcomes of transvaginal radiofrequency ablation for symptomatic leiomyomas

OBJECTIVE

Describe the effect of transvaginal radiofrequency ablation for leiomyoma in symptomatic patients and post procedure follow-up.

MATERIAL AND METHODS

A retrospective forward-looking observational study was performed including 63 patients who underwent transvaginal radiofrequency ablation between January 2016 and December 2022 at San Cecilio University Hospital in Granada, Spain. The variables registered were: age, parity, the clinical features that lead to the medical visit and pre-surgical treatment. Prior to the procedure, leiomyoma location and volume were determined by transvaginal ultrasound. Follow-ups were scheduled at 6 and 12 months to evaluate symptom improvement, adverse outcomes, leiomyoma volume and if any necessary post-surgical treatment was required.

RESULTS

Mean leiomyoma volume at baseline, 6 months and 12 months was 83.3 (24.9-130.7), 42.4 (4.7-89.0) and 19.2 (1.9-80.4) cm3, respectively (p < .001). Significant differences were found between the baseline and 12 month visits (p < .001). At the annual follow-up, the mean rate of volume reduction was 79.5 %, being higher in women who reported symptom improvement compared to those who reported no change in symptom intensity from baseline (84.6% vs. 30.8 %). Patients with a lower initial volume and age over 40 were more likely to have treatment efficacy. 8 pregnancies were registered post procedure.

CONCLUSION

Radiofrequency is well tolerated, allowing for same-day discharge, rapid recovery and a safe approach for women who want to preserve their reproductive potential. Initial volume and age over 40 appear to be factors that should be considered in patient selection. Further studies are needed to continue evaluating the outcomes and identifying predictive factors.

The Future of Minimal-Access Myoma Surgery with In-Bag Contained Morcellation

Contained electromechanical morcellation has emerged as a safety approach for laparoscopic myomatous tissue retrieval. This retrospective single-center analysis evaluated the bag deployment practicability and safety of electromechanical in-bag morcellation when used for big surgical benign specimens. The main age of patients was 39.3 years (range 21 to 71); 804 myomectomies, 242 supracervical hysterectomies, 73 total hysterectomies, and 1 retroperitoneal tumor extirpation were performed. A total of 78.7% of specimens weighed more than 250 g (n = 881) and 9% more than 1000 g. The largest specimens, weighing 2933 g, 3183 g, and 4780 g, required two bags for complete morcellation. Neither difficulties nor complications related to bag manipulation were recorded. Small bag puncture was detected in two cases, but peritoneal washing cytology was free of debris. One retroperitoneal angioleiomyomatosis and three malignancies were detected in histology (leiomyosarcoma = 2; sarcoma = 1); therefore, patients underwent radical surgery. All patients were disease-free at 3 years follow-up, but one patient presented multiple abdominal metastases of the leiomyosarcoma in the third year; she refused subsequent surgery and was lost from follow-up. This large series demonstrates that laparoscopic bag morcellation is a safe and comfortable method to remove large and giant uterine tumors. Bag manipulation takes only a few minutes, and perforations rarely occur and are easy to detect intraoperatively. This technique did not result in the spread of debris during myoma surgery, potentially avoiding the additional risk of parasitic fibroma or peritoneal sarcoma.

Application Effect of Laparoscopic Myomectomy and Comprehensive Rehabilitation Nursing on Patients with Uterine Fibroids

Background. Uterine fibroids are most common in women aged 30-50 and are the most common benign gynecological tumors. Relevant data suggest that about 25% of patients with uterine fibroids are at childbearing age. Uterine fibroids not only cause the discomfort symptoms, and affect the pregnancy, but also have certain malignant transformation risk, thus needed to be treated positively and promptly. Aim. This study is aimed at exploring the effect of laparoscopic myomectomy and comprehensive rehabilitation nursing on patients with uterine fibroids. Methods. The clinical data of 110 cases of uterine fibroids admitted to our hospital from August 2019 to December 2021 were analyzed retrospectively, and they were divided into two groups according to postoperative rehabilitation strategies. Both groups were treated with laparoscopic myomectomy. The A group was treated with routine rehabilitation strategy, while the B group was treated with comprehensive rehabilitation nursing strategy. The differences in operation-related indicators, stress factors, inflammatory factors, nutritional indicators, knowledge mastery, occurrence of adverse symptoms and pain scores, negative emotion scores, nursing satisfaction, and simplified comfort status scale (GCQ) scores between the two groups under nursing strategies were compared. Results. The postoperative exhaust time ( $13.14\pm 2.03$ ) h, bed time ( $9.86\pm 1.94$ ) h, postoperative hospital stay ( $4.37\pm 1.31$ ) d, and total hospital stay ( $6.78\pm 1.69$ ) d in the B group were shorter than those in the A group, and the hospitalization expenses ( $0.74\pm 0.25$ ) million were less than those in the A group ( $P<0.05$ ). Before operation, stress factors, inflammatory factors, and nutritional indexes were compared between the two groups ( $P>0.05$ ). On the 3rd day after operation, tumor necrosis factor-α (TNF-α), cortisol (Cor), norepinephrine (NE), and interleukin-1β (IL-1β) in the two groups showed a significantly upward trend compared with those before operation, and albumin and transferrin were significantly fell compared with those before operation. However, the values of stress factor and inflammatory factor in the B group were significantly lower than those in the A group, and the values after the decrease of nutritional index were significantly higher than those in the A group ( $P<0.05$ ). The pain scores at 24 h, 48 h, and 72 h after operation in the B group were significantly lower than those in the A group ( $P<0.05$ ). Negative emotions, nursing satisfaction, and GCQ scores were compared between the two groups before intervention ( $P>0.05$ ). After the intervention, the scores of Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) in the two groups were significantly lower than those before the intervention, and the scores of nursing satisfaction and GCQ were higher than those before the intervention. The values of negative emotions in the B group after the decline were significantly lower than those in the A group, while the values of nursing satisfaction and GCQ after the increase were higher than those in the A group ( $P<0.05$ ). The excellent and good rate of knowledge acquisition in the B group was 94.55% (52/55), which was significantly higher than 78.18% (43/55) in the A group ( $P<0.05$ ). The incidence of adverse symptoms in the B group was 9.09% (5/55), which was lower than 21.82% (12/55) in the A group, while the difference was not statistically significant ( $P>0.05$ ). Conclusion. Laparoscopic myomectomy combined with comprehensive rehabilitation nursing can reduce the postoperative stress state of patients with uterine fibroids, improve patient satisfaction, reduce adverse emotions, and promote rehabilitation.

Radiofrequency ablation methods for uterine sparing fibroid treatment

PURPOSE OF REVIEW

This article provides a clinical review of radiofrequency ablation (RFA) for the treatment of uterine leiomyomas.

RECENT FINDINGS

RFA is an effective and durable treatment for fibroids with sustained improvements in fibroid volume, bleeding, and patient reported outcomes with low reintervention rates. Although fertility data is limited, it is overall positive and may represent a uterine conserving and fertility preserving treatment modality.

SUMMARY

RFA is a safe and effective uterine preserving treatment option for symptomatic leiomyomas.

Transcervical radiofrequency ablation of fibroids that are 5 cm or larger in women with abnormal uterine bleeding

INTRODUCTION

Fibroids are the most common benign uterine tumors. Transcervical radiofrequency ablation with the Sonata® System offers a minimally invasive, incisionfree, organ-preserving therapy, with intraoperative visualization of fibroids using intrauterine ultrasound guidance. To demonstrate the effectiveness of transcervical radiofrequency ablation of fibroids that are 5 cm or larger using the Sonata® System, this retrospective analysis was collected.

METHOD

151 patients have been treated with this method in our department up to the time of this analysis. Only patients with at least one fibroid of ≥5 cm and with bleeding symptoms, who were treated with the Sonata® System were included in this retrospective study. A total of 50 patients were included in the study and 57 fibroids were treated.

RESULTS

A total of 57 fibroids were detected and treated, however FIGO 1 and 2 fibroids (in total three fibroids were excluded). The smallest fibroid was 4 cm and the largest fibroid was 12 cm. A single ablation was performed in 18 cases, two ablation steps in 16 cases, three ablation steps in 13 cases, and more than three ablation steps in three cases. Depending on ablation steps, the shortest ablation time was 3 min 15 s and the longest ablation time was 25 min 6 s, with an average time of 9 min 12 s. 86% of patients reported an improvement of symptoms Conclusion: Thus, the Sonata® System is a simple, minimally invasive, rapid and successful method that shows significant improvement of symptoms even in large myomas from ≥5 cm.

Pregnancy Outcomes After Transcervical Radiofrequency Ablation of Uterine Fibroids with the Sonata System

Objective:

To describe pregnancy outcomes in women who conceived after undergoing transcervical fibroid ablation (TFA) as treatment for symptomatic uterine fibroids.

Materials and Methods:

TFA was used to treat symptomatic uterine fibroids with radiofrequency energy, both under clinical trial protocol and commercial usage in hospitals in Europe, the United Kingdom, Mexico, and the United States. All women who reported pregnancies to their physicians after undergoing TFA with the Sonata^® System and provided consent for use of their data were included.

Results:

There have been 36 pregnancies representing 20 deliveries among 28 women who were treated with TFA. Five women conceived more than once postablation, and four conceived as a result of assisted reproductive technology (ART). Outcomes include 8 vaginal deliveries, 12 Cesarean sections, 3 therapeutic abortions, and 8 first trimester spontaneous abortions (four occurring in a patient with a history of recurrent pregnancy loss and an immunologic disorder). Five women are currently pregnant, two of whom previously delivered after TFA. There were no 5-minute Apgar scores <7, and all neonates weighed >2500 g. All deliveries occurred at ≥37 weeks except for one delivery at 35 6/7 weeks. There were no uterine ruptures or abnormal placentation and no reports of postpartum hemorrhage or stillbirths. Ablated fibroids included transmural, submucous, and intramural myomata up to 7 cm in diameter.

Conclusions:

Normal pregnancy outcomes at term have occurred after TFA with the Sonata System, including in women with recurrent abortion and in those undergoing ART. There were no instances of low Apgar scores, low birthweight, stillbirth, postpartum hemorrhage, or uterine rupture (FAST-EU, NCT01226290; SONATA, NCT02228174; SAGE, NCT03 118037).
