Post treatment and 3 month contrast enhanced MRI findings following HIFU of submucosal fibroids: a retrospective study.

PURPOSE: This study used contrast-enhanced MRI (CE-MRI) examination to assess the efficacy of high-intensity focused ultrasound (HIFU) for submucosal fibroids. METHODS: A total of 81 submucosal fibroids, including 33 cases of type 1, 29 cases of type 2, and 19 cases of type 2-5, treated by HIFU were retrospectively reviewed. CE-MRI was performed in all cases immediately after HIFU, the non-perfused volume ratio (NPVR) and the degree of endometrial impairment were recorded. Thereafter, CE-MRI was repeated in all cases after three months, and the change of fibroid volume shrinkage rate (FVSR), NPVR and the degree of endometrial impairment were recorded. RESULTS: The immediate NPVR was 86.4 ± 19.3% in type 1, 90.0 ± 13.3% in type 2 and 90.3 ± 7.2% in type 2-5. Among 81 fibroids, grades 0, 1, 2 and 3 endometrial impairments were observed in 38.3%, 16.1%, 14.8% and 30.9%, respectively. Three months later, NPVR was 68.0 ± 36.4% in type 1, 74.3 ± 27.7% in type 2 and 85.0 ± 16.1% in type 2-5. Grades 0, 1, 2 and 3 endometrial impairments were observed in 64.2%, 23.5%, 9.9% and 2.4%.FVSR was 49.0 ± 1.3% in type 1, 39.6 ± 1.7% in type 2 and 37.2 ± 2.1% in type 2-5. The FVSR in submucosal fibroid type 1 was superior to type 2 and type 2-5 (p < 0.05). The NPVR of submucosal fibroids in type 2-5 were higher than type 1 (p < 0.05) .There was no difference among different types of submucosal fibroids in endometrial impairment (p > 0.05) three months after HIFU. CONCLUSIONS: At three months after HIFU, FVSR was better for submucosal fibroid type 1 than for type 2 and type 2-5. And there was no difference in endometrial impairment among the different types of submucosal fibroid groups.

Optimal treatment options for uterine submucosal fibroids: Percutaneous microwave ablation versus transcervical resection of myoma.

OBJECTIVES: To compare the efficacy and safety of percutaneous microwave ablation (PMWA) and transcervical resection of myoma (TCRM) for submucosal fibroids. METHODS: From January 2019 to January 2021, we conducted a randomized controlled study involving patients with symptomatic uterine submucosal fibroids. Questionnaires were also used to measure the uterine fibroid symptom (UFS) scores and quality of life (QoL) scores before and after treatment at 3, 6, and 12 months. Outcomes, adverse events, hemoglobin recovery, and submucosal fibroid volume of both groups were also compared. Operation time, amount of bleeding, hospital stay time, and occurrence of complications were compared in groups with fibroids of different lengths. RESULTS: Follow-up after surgery showed that UFS scores at 3, 6, and 12 months were significantly lower in each group, while QoL scores increased significantly. For fibroids less than 3 cm, surgical time was 34.2 ± 9.9 min, incidence of perioperative complications was 4.2%, and both decreased significantly, compared to the surgical time of the PMWA group (40.0 ± 8.1 min) and incidence of perioperative complications (24%; p < .05 for both). For uterine submucosal fibroids >5 cm, the operation time in the PMWA group was 92.7 ± 16.0 min, intraoperative bleeding volume was 22.7 ± 6.4 mL, and hospital stay was 2.7 ± 1.1 days, which were significantly less than the procedural time (107 ± 11.9 min), intraoperative bleeding loss (45.9 ± 12.8 mL), and length of hospital stay (5.0 ± 1.1 days) in the TCRM group. The differences were statistically significant (p < .05). CONCLUSIONS: PMWA and TCRM were both effective treatments for uterine submucosal fibroids. For fibroids shorter than 3 cm in length, especially pedicled submucosal fibroids, TCRM has absolute advantages; however, for uterine submucosal fibroids >5 cm, PMWA avoids perioperative complications, such as uterine perforation, water poisoning syndrome, and the need for repeat surgery, and is considered the preferred mode of treatment. Therefore, personalized treatment should be used for different patients with uterine submucosal fibroids.

Comparison of ultrasound-guided high-intensity focused ultrasound ablation and hysteroscopic myomectomy for submucosal fibroids: a retrospective study.

OBJECTIVE: To compare the safety, reintervention and pregnancy outcomes between ultrasound-guided high intensity focused ultrasound (USgHIFU) and hysteroscopic myomectomy (HM) for submucosal fibroids. MATERIALS AND METHODS: A total of 215 patients with a solitary submucosal fibroid treated by USgHIFU or HM at the third Xiangya Hospital were retrospectively reviewed. Among them, 58 treated with USgHIFU, 157 treated with HM. RESULTS: A significant difference was observed in size, location and type of the fibroids, effective rate, and cumulative reintervention rate between the two groups (p < .05). The size of the fibroids was 57.9 ± 1.9 mm in the USgHIFU group, while it was 32.6 ± 1.2 mm in the HM group. The number of the fibroids at horn or fundus/uterine cavity was 16/42 in the USgHIFU group, while it was 21/136 in the HM group. The number of type I/II/2-5 was 16/17/25 in the USgHIFU group, while it was 133/24/0 in the HM group. In the USgHIFU group, the effective rate was 100% and the cumulative reintervention rate at 50 (17-97) months was 19.0%, while in the HM group, it was 94.3% and 7.6%, respectively. During the follow-up period, the pregnancy rate was 22.4% (13/58) and the reintervention rate due to invalid and recurrence was 15.5% (9/58) in the USgHIFU group, while they were 18.5% (29/157) and 7.0% (11/157) in the HM group. No significant difference was observed between the two groups (p > .05). Furthermore, the reintervention rate was positively correlated with age, treatment methods and parity and fertility requirements. No other significant difference was observed between the two groups. CONCLUSIONS: Both USgHIFU and HM are safe and effective in treating submucosal fibroids. Compared with the HM group, the USgHIFU group had lower postoperative complications, but higher reintervention rate, with similar recurrence rate, pregnancy rate and reintervention rate due to invalid and recurrence. Reintervention was related to age, treatment methods, parity and fertility requirements.

Comparison of outcomes of hysteroscopic myomectomy of type 2 submucous fibroids greater than 4 cm in diameter via pretreatment with HIFU or GnRH-a.

OBJECTIVE: To compare the efficacy and safety of high-intensity focused ultrasound (HIFU) and gonadotropin-releasing analogues (GnRH-a) as pretreatments for the hysteroscopic transcervical resection of myoma (TCRM) for type 2 submucosal fibroids greater than 4 centimeters in diameter. MATERIALS AND METHODS: Seventy-nine patients were assigned into two groups according patient preference: 42 in HIFU and 37 in GnRHa. TCRM was performed after 3 months of pretreatment with HIFU or GnRHa. RESULTS: Following pretreatment with HIFU or GnRHa, uterine-fibroid symptom (UFS) scores and hemoglobin levels (HGB) showed improvement. The fibroid maximum diameter, size of fibroids, and volume of the uterus were decreased. Following HIFU pretreatment, one case reported complete vaginal fibroid expulsion, and four reported partial fibroid expulsion. No similar cases were found in the GnRHa group. Eighteen patients were lost to follow-up prior to TCRM. Among the 31 patients in HIFU, the fibroids were downgraded to type 0 in 10 cases and type 1 in 5 cases. Of the 30 patients in GnRHa, the treated fibroids were downgraded to type 1 in 9 cases. The mean operation time and intraoperative blood loss of the HIFU group were significantly lower than those in the GnRHa group. No significant differences were observed in the incidence of intraoperative complications and the one-time resection rate of fibroids between the two groups (p>.05). CONCLUSIONS: HIFU seems to be superior to GnRHa as a pretreatment method prior to TCRM for type 2 submucosal fibroids greater than 4 centimeters in diameter.

The (cost) effectiveness of procedural sedation and analgesia versus general anaesthesia for hysteroscopic myomectomy, a multicentre randomised controlled trial: PROSECCO trial, a study protocol.

BACKGROUND: In women with abnormal uterine bleeding, fibroids are a frequent finding. In case of heavy menstrual bleeding and presence of submucosal type 0-1 fibroids, hysteroscopic resection is the treatment of first choice, as removal of these fibroids is highly effective. Hysteroscopic myomectomy is currently usually performed in the operating theatre. A considerable reduction in costs and a higher patient satisfaction are expected when procedural sedation and analgesia with propofol (PSA) in an outpatient setting is applied. However, both safety and effectiveness - including the necessity for re-intervention due to incomplete resection - have not yet been evaluated. METHODS: This study is a multicentre randomised controlled trial with a non-inferiority design and will be performed in the Netherlands. Women > 18 years with a maximum of 3 symptomatic type 0 or 1 submucosal fibroids with a maximum diameter of 3.5 cm are eligible to participate in the trial. After informed consent, 205 women will be randomised to either hysteroscopic myomectomy using procedural sedation and analgesia with propofol in an outpatient setting or hysteroscopic myomectomy using general anaesthesia in a clinical setting in the operating theatre. Primary outcome will be the percentage of complete resections, based on transvaginal ultrasonography 6 weeks postoperatively. Secondary outcomes are cost effectiveness, menstrual blood loss (Pictorial blood assessment chart), quality of life, pain, return to daily activities/work, hospitalization, (post) operative complications and re-interventions. Women will be followed up to one year after hysteroscopic myomectomy. DISCUSSION: This study may demonstrate comparable effectiveness of hysteroscopic myomectomy under procedural sedation and analgesia versus general anaesthesia in a safe and patient friendly environment, whilst achieving a significant cost reduction. TRIAL REGISTRATION: Dutch trial register, number NTR5357 . Registered 11th of August 2015.

The potential role of elastography in differentiating between endometrial polyps and submucosal fibroids: a preliminary study.

Endometrial polyps and submucosal fibroids are common causes of abnormal uterine bleeding (AUB) and less commonly infertility. The prevalence of such intrauterine lesions increases with age during the reproductive years, and usually decreases after menopause. The first-line imaging examination in the diagnosis of endometrial polyps as well as submucosal fibroidsis ultrasound, but its accuracy is not obvious. Elastography is an ultrasound-based imaging modality that is used to assess the stiffness of examined tissues. Considering the fact that endometrial polyps derive from soft endometrial tissue and submucosal fibroids are made of hard muscle tissue, elastography seems a perfect tool to differentiate between such lesions. I present two groups of patients with AUB and intrauterine lesions suspected on ultrasound. In the first group of patients, elastography showed that the stiffness of the lesion was similar to the endometrium and softer than the myometrium. During hysteroscopies endometrial polyps were removed. In the second group of patients, elastography showed that the stiffness of the lesion was similar to the myometrium and harder than the endometrium. During hysteroscopies submucosal fibroids were removed. In both groups, the diagnosis was confirmed by the pathological examination in all cases. It was demonstrated that with the use of elastography it is possible to assess the stiffness of intrauterine lesions, which may be useful in differentiating between endometrial polyps and submucosal fibroids.

Comparison of Focused Ultrasound Surgery and Hysteroscopic Resection for Treatment of Submucosal Uterine Fibroids (FIGO Type 2).

The aim of the study described here was to compare the effectiveness of focused ultrasound surgery (FUS), which uses high-intensity focused ultrasound to perform tissue ablation, with that of hysteroscopic transcervical resection of myoma (TCRM) for the treatment of type 2 submucosal fibroids. A prospective cohort study was performed in patients who underwent FUS or TCRM from January 2012 to December 2014. Uterine Fibroid Symptom (UFS) and Quality of Life (QoL) questionnaires were used to measure fibroid-related symptoms and quality of life before and at 3, 6 and 12 mo after treatment. Technical results, adverse events and post-operative recovery times of both groups were also compared. A total of 81 patients with at least one type 2 submucosal fibroid were enrolled. The mean diameter of type 2 submucosal fibroids was 3.8 ± 0.9 cm (range: 2.0-5.0 cm) for 39 patients in the FUS group and 3.5 ± 0.8 cm (range: 2.0-4.8 cm) for the 42 patients enrolled in the TCRM group. No major complication occurred in any patients for either treatment. In both groups, the UFS score decreased significantly and the QoL score increased significantly from baseline successively at 3, 6 and 12 mo post-treatment (p < 0.05). Time spent in hospital post-treatment was significantly shorter (2.56 ± 0.98 d) for the FUS group compared with the TCRM group (3.31 ± 0.60 d) (p < 0.05). Time to return to work after treatment was also significantly shorter for the FUS group (3.14 ± 0.83 d) than for the TCRM group (6.09 ± 0.9 d) (p < 0.05). FUS and TCRM are both tolerable and effective treatments with significant improvement of symptom and quality of life for patients with type 2 submucosal fibroids ≤5 cm in diameter.

Operative hysteroscopy in a jamaican cohort / Histeroscopia operatoria en una cohorte jamaicana

OBJECTIVE: The objective of this study is to determine the indications, success, and complications of operative hysteroscopy performed at The University of the West Indies (UWI). METHODS: A five-year retrospective cohort study was done of women undergoing operative hysteroscopy at the Hugh Wynter Fertility Management Unit (HWFMU) of the University of the West Indies from January 1, 2001 to December 31, 2005. The demographics of the patients, indications, complications of the procedure and postoperative follow-up were assessed. Patient's post-procedural quality of life was assessed by a questionnaire. RESULTS: During this period, 92 operative hysteroscopies were performed on 87 patients, with repeat procedures being performed in three patients. The mean age of patients undergoing operative hysteros-copy was 36.65 years with a range of 23 to 50 years. The main indications for operative hysteroscopy at the HWFMU were submucosal fibroids (50%), intrauterine synechiae (26%) and removal of an intrauterine contraceptive device (11%). There were four procedure-related complications, all of which occurred during myomectomy and required hospitalization. CONCLUSION: Operative hysteroscopy is a safe and highly effective therapy for carefully selected women. As a consequence of technological advancements, an increasing number of gynaecological conditions, traditionally treated by laparotomy, can now be treated safely and effectively using outpatient operative hysteroscopy.

OBJETIVO: El objetivo de este estudio es determinar las indicaciones, éxito, y complicaciones de las histeroscopías operatorias realizadas en la Universidad de West Indies (UWI). MÉTODOS: Se realizó un estudio de cohorte retrospectivo de cinco años con mujeres sometidas a Histeroscopia operatoria en la Unidad de Fertilidad "Hugo Wynter", en la Universidad de West Indies (HWFMU), del 1ero de enero de 2001 al 31 de diciembre de 2005. Se evaluaron los datos demográficos de los pacientes, así como las indicaciones, las complicaciones del procedimiento y el seguimiento post-operatorio. Se aplicó un cuestionario para evaluar la calidad de vida del paciente luego del procedimiento. RESULTADOS: Durante este período se realizaron 92 histeroscopías operatorias a 87 pacientes, repitiéndose los procedimientos en tres pacientes. La edad promedio de los pacientes sometidos a Histeroscopia operatoria fue 36.65 años, con una rango de 23 a 50 años. Las indicaciones principales para la histeroscopía operatoria en la Unidad HWFMU fueron los miomas submucosos (50%), las sinéquias intrauterinas (26%) y la extracción del dispositivo anticonceptivo intrauterino (11%). Hubo cuatro complicaciones relacionadas con los procedimientos, todas las cuales tuvieron lugar durante la miomectomía y requirieron hospitalización. CONCLUSIÓN: La histeroscopía operatoria es una terapia segura y altamente efectiva para mujeres cuidadosamente seleccionadas. Como consecuencia de los avances tecnológicos, un número creciente de condiciones ginecológicas, tradicionalmente tratadas mediante laparotomía, pueden ahora ser tratadas con seguridad y efectividad mediante histeroscopía operatoria ambulatoria.
