Aims and objectives

Background: Diagnosis of thyroid’s nodules detected is increasing. Alternative technics are developed to treat benign nodules without surgery. The most popular alternative technic is US-guided RadioFrequency, done in Surgery or Interventional Room, with local anesthesia and from time to time short total anesthesia. Thepurposeof our study is toevaluate prospectively, morphological and clinical responseof ultrasound guidedRadioFrequency in benign thyroid nodules inducing discomfort.

Methods and materials

Technic: By transisthmic approach, we are going to treat all the nodule by successively spots of radiofrequency deposit. This approach permits to stay far away from main vascular or nervous structure, oesophagus and trachea. It is the « Moving shot technic» described by Professor Baek from South Korea more than 10 years ago. In our study we used Monopolar 18G (1,01mm), cooled, tipactive 10mm RF electrode and Generator VIVA RF (35-45 W). Patients: From Oct 2016 to June 2018,52 patients (41 F. / 11 M.)...

Results

Volumic analysis : The volume decrease was about 40% after 1 month, 70% after 6 months and near 95% for the best response after 1 year. Clinical Analysis: The objective response measured by Visual Analogical Scale showsclear improvement of the discomfort and most of the patients are satisfied of the treatmenteven only few of them are at 1 year after treatment. No serious complication is to deplored. Biological Analysis: TSH at 2 months is normal for all patients, even in those with Autonomously Thyroid Functioning...

Conclusion

This french multicentric study shows that us-guided radiofrequency of benign thyroid nodules appears safe and efficient and should be an alternative to thyroidectomy.
