Ultrasound and Cytological Evaluation 3 Years After Radiofrequency Thermal Ablation of Benign Thyroid Nodules : a Prospective Exploratory Cohort of 180 Nodules

There is no scientific data on post-thermal ablation cytological aspects, but treated nodules that grow back significantly after a procedure justify a new cytology in order not to ignore a neoplastic process. The EU-TIRADS classification usually used to stratify the risk of cancer (and to justify a fine needle aspiration biopsy) of thyroid nodules is not validated for nodules treated by thermal ablation (TA) (post-RF nodules). However, these nodules often acquire ultrasound criteria of suspicion making it necessary to develop an ultrasound stratification of the risk of malignancy specific to nodules treated by TA. The objective of this work is to describe the ultrasound and cytological aspects of these treated nodules by performing a systematic assessment at 3 years after thermal ablation including systematic neck ultrasound and fine needle aspiration biopsy. Thus, an ultrasound and cytological atlas (Bethesda classification 2017) of nodules treated by thermal ablation will be constituted.

The Effect of Virtual Reality Applications

Thyroid nodules are a common health problem in the adult population. Ultrasound-guided fine-needle aspiration biopsy (FNAB) is the standard diagnostic procedure for evaluating suspected thyroid nodules. Although FNAB is generally considered a safe and minimally invasive procedure, it may cause pain, anxiety, and fear. In addition, patients are instructed not to speak or cough during the procedure, and the biopsy may need to be repeated if an insufficient specimen is obtained, which can further increase psychological distress. Therefore, effective non-pharmacological interventions may help improve patient comfort during the procedure. Distraction is a widely used non-pharmacological pain management strategy that reduces patients' perception of pain and distress by redirecting their attention away from the procedure. Virtual reality (VR) is an immersive distraction technique that has shown promise in reducing procedure-related discomfort in various clinical settings. This open-label randomized controlled trial aimed to evaluate the effect of virtual reality on pain as the primary outcome and anxiety and fear of pain as secondary outcomes in patients undergoing ultrasound-guided fine-needle aspiration biopsy of suspected thyroid nodules.
