How to manage the @entity1 with unsatisfactory results after XXXX ablation for thyroid nodules: role of radiofrequency ablation.

@entity1 @entity1068 @entity353
PURPOSE: Although @entity1068 ablation (EA) is effective in the treatment of cystic thyroid nodules, it is less effective in nodules with solid component. Therefore refractory cases with solid component require another treatment modality such as radiofrequency ablation (RFA), which is effective in both solid and cystic thyroid nodules. We prospectively evaluated the efficacy of additional RFA and factors related to @entity353 in @entity1 showing unsatisfactory results after a single session of EA. MATERIALS AND METHODS: Of 94 @entity1 with predominantly cystic thyroid nodules who underwent EA, 20 @entity1 underwent additional RFA because of incompletely resolved clinical problems (symptomatic score reduction <50%) and presence of residual solid component at 1-month follow-up on ultrasonography. Improvement of clinical symptoms and nodule @entity353 were evaluated 6 month later. We evaluated factors related to nodule @entity353 after EA and RFA. RESULTS: RFA after a single session of EA was effective in reducing mean symptom score from 4.8 to 1.1 (p<0.001), mean cosmetic score from 3.5 to 1.4 (p<0.001) and mean nodule volume from 11.3 to 0.9 mL (p<0.001). The only independent factor related to @entity353 after EA was the presence of a solid component (p<0.001), and EA was less effective in nodules when solid component >20% (p=0.001). We identified no factors related to @entity353 after RFA. CONCLUSION: RFA is effective in treatment of benign predominantly cystic thyroid nodules in @entity1 whose clinical problems were incompletely resolved after EA.
