Ultrasound-guided treatment of predominantly cystic thyroid nodules: a comparative study between lauromacrogol injection therapy and radiofrequency ablation
To explore the efficacy of ultrasound-guided lauromacrogol injection therapy (PLIT) and radiofrequency ablation (RFA) for treating predominantly cystic thyroid nodules.
Methods:
A total of 76 patients with predominantly cystic thyroid nodules admitted to Shuguang Hospital from Feb. 2015 to May. 2018 were treated with PLIT (
N
=51) or RFA (
N
=25). The clinical efficacy and adverse reactions of the patients were analyzed and compared after treatment.
Results:
At 12 months after operation
the total ef
fective rate of RFA group was 100.00% (25/25)
which was higher than that of PLIT group (84.31%
43/51)
and the difference was statistically significant (
P
<0.05). The rate of adverse reactions was 13.73% (7/51) in the PLAT group and 16% (4/25) in the RFA group. There was no significant difference in the rate of adverse reactions between the two groups (
P
>0.05).
Conclusion:
Ultrasound-guided RFA is more effective for predominantly cystic thyroid nodules. The PLIT has economic advantages. Both methods are worthy of clinical promotion.
