Summary
Sonography-guided OK-432 sclerotherapy effectively treats benign thyroid cysts. This safe and useful alternative therapy showed good responses in 73.3% of patients, with no significant complications.
Area of Science:
- Endocrinology
- Interventional Radiology
Background:
- Benign thyroid cysts can be recurrent and symptomatic.
- Traditional treatments like aspiration may have limited long-term efficacy.
Purpose of the Study:
- To evaluate the efficacy and safety of sonography-guided OK-432 sclerotherapy for benign thyroid cysts.
- To assess treatment outcomes in patients with recurrent cystic thyroid nodules.
Main Methods:
- Review of 20 patients with recurrent benign thyroid cysts treated with sonography-guided OK-432 injections.
- OK-432 was administered at 0.05 mg/ml, with repeat treatments up to three times if needed.
- Patients were cytologically negative for malignancy.
Main Results:
- 15 patients completed the study; 11 (73.3%) showed good response (cyst size <10 mm).
- 4 patients (26.7%) exhibited poor responses.
- All patients tolerated the therapy well, with no significant morbidity or complications.
Conclusions:
- Sonography-guided OK-432 sclerotherapy is an effective and safe treatment for benign thyroid cysts.
- It offers a valuable alternative therapeutic option for selected patients with recurrent cystic nodules.
- The procedure demonstrates a favorable safety profile with minimal complications.
