Brief Summary:
To perform the use of radiofrequency myolysis (RFM) for the treatment of intra-uterine fibroids through less invasive access by combining trans-vaginal ultrasound, hysteroscopy and laparoscopy

Condition or disease Intervention/treatment Phase

Detailed Description:
Given that the RF ablation of solid tumors of the liver and other organs is successfully used as a usual approach, the investigators have decided to transfer this technology to an original treatment of uterine fibroids. The access to each individual fibroid was determined considering passage of the needle towards its centre through only compromised tissue and by the shortest possible route by combining trans-vaginal ultrasound, hysteroscopy and laparoscopy. To optimize radiofrequency myolysis, in fact, the investigators decided to improve the procedure by inserting three innovative elements: application of a virtual needle tracking system to follow the RF electrode during the ablation session, real-time monitoring of RF ablation by contrast-enhanced ultrasound and systematic biopsy of the lesions before electro-coagulation.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 54 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective Study on Radiofrequency Ablation of Uterine Fibroids (Myolysis) Under Ultrasound and Endoscopic Guidance, in Single or Combined Approach
Actual Study Start Date : March 1, 2017
Actual Primary Completion Date : March 1, 2019
Actual Study Completion Date : March 31, 2019

Arm Intervention/treatment
Experimental: Radiofrequency myolysis of uterine fibroids
54 premenopausal participants with symptomatic uterine myomas
The ablation device consisted of an radiofrequency (RF) energy generator (STARmed, RF generator VRS01) and an electric pump for the continuous cooling of the electrode tip. The RF generator to which the electrode (STARmed Gyeonggi-Do, Korea) is connected displays simultaneously the temperature of the electrode tip, the tissue impedance characteristics, the power and the ablation time. A 35 cm long 18Gauge internally cooled electrode with an exposed tip of 10 mm or a variable exposed tip was used
Other Names:
  • Radiofrequency myolysis (RFM)
  • RF lesion generator for tissue ablation during surgical procedures. Sterile single-use RF coagulation monopolar electrode.

Primary Outcome Measures :
  1. Myoma volumes after radiofrequency myolysis (RFM) [ Time Frame: 12 months ]
    The outcomes evaluated after RFM were myoma volumes (cubic centimeters)

  2. Myoma diameters after radiofrequency myolysis (RFM) [ Time Frame: 12 months ]
    The outcomes evaluated after RFM were myoma diameters (centimeters)

  3. Uterine Fibroid Symptom and Quality of Life (UFS-QOL) score after radiofrequency myolysis (RFM) [ Time Frame: 12 months ]
    Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire with scores ranging from 0 to 100, were higher QOL scores mean a better health-related QOL 1 and a 10-point scale used for each reported symptom.

Secondary Outcome Measures :
  1. Surgical time of radiofrequency myolysis (RFM) [ Time Frame: 12 months ]
    The surgical time (minutes) for each different type of surgical access

  2. Surgical time of radiofrequency myolysis (RFM) assisted by new technologies [ Time Frame: 12 months ]
    The reduction of surgical time (minutes) with the use of a virtual global positioning system (GPS) track system or a contrast-enhanced ultrasound during the ablation

  3. Pre-intervention biopsy associated to radiofrequency myolysis (RFM) [ Time Frame: 12 months ]
    The number of biopsies for treated fibroma
