Abstract:
Objective To investigate the efficacy,safety and operation time of ultrasound-guided percutaneous polidocanol injection chemical ablation through 17 G coaxial needle for predominantly cystic thyroid nodules.Methods The clinical data of 176 patients with predominantly cystic thyroid nodules,who received ultrasound-guided percutaneous polidocanol injection chemical ablation at authors'hospital from January 2020 to June 2023,were retrospectively analyzed.Of the 176 patients,20 mL syringe needle was used in 96(control group)and 17 G coaxial needle was used in 80(study group).The clinical safety,efficacy,and operation time were compared between the two groups.Results After the chemical ablation therapy,the volume of thyroid nodules was obviously decreased in both groups,but the difference in the volume reduction ratio(VRR)between the two groups was not statistically significant(P＞0.05).The incidence of complications and the operation time in the study group were remarkably lower than those in the control group(both P＜0.05).Conclusion In treating predominantly cystic thyroid nodules with ultrasound-guided percutaneous polidocanol injection chemical ablation,the use of 17 G coaxial needle is superior to the use of 20 mL syringe needle in reducing the incidence of complications and in shortening the operation time,therefore,this technique is suitable for beginners to adopt.
