Abstract

Objective: To observe clinical efficacy of ultrasound-guided fine-needle aspiration(US-FNA) of benign thyroid cysts or partially cystic thyroid nodules. Methods: Clinical data of 98 patients were divided into different groups according to cystic component and ultrasound features. The clinical efficacy was compared and valued according to the change of cyst size and the postoperative adverse reaction rate. Results: The total effective rate of simple cyst group(94.7%) after US-FNA was higher than that of the complexity cyst group(83.3%), and the difference was statistically significant(P=0.001). The clinical efficacy of the dark bloody(90.0%), yellow jell(80.0%) and yellow sticky group(87.5%) after US-FNA treatment was better than that of yellow/colorless group(50%), and the differences were statistically significant(P=0.001, P=0.001, P=0.023). In the comparison of the recurrence rate among groups according to the degree of aspiration, the recurrence rate of the complete group(7.0%) was obviously lower than that of the other two groups(66.7%, 47.0%), and the difference was statistically significant(P=0.001, P=0.001). In the comparison of the postoperative adverse reactions, the incidence of adverse reactions of simple cyst group(10%) was much lower than that of the complexity group(20%) and the difference was statistically significant(P=0.001). Conclusion: The US-FNA is a relatively safe and feasible treatment for thyroid cyst or partly cystic thyroid nodules, especially for the simple cyst and that with aspirates close to gelatin. The postoperative complications are milder, and most can relieve by itself. Aspiration should be done as thoroughly as possible to reduce the recurrence rate effectively.
