Abstract:

Objective

To evaluate the clinical value of sonic division assisted technique in fine needle aspiration biopsy (FNAB) of suspicious papillary thyroid microcarcinoma.

Methods

Patients with suspected papillary thyroid microcarcinoma were divided into control group and experimental group. The control group adopted the in-plane puncture method with bare hands, and the experimental group adopted the non-co-planar puncture method with rubber band sonic division assisted positioning technology. The puncture time, frequency, inadequate diagnostic rate, malignant coincidence rate, and complication rate were compared between the two groups.

Results

There were 60 nodules in 58 cases in the control group and 64 nodules in 58 cases in the experimental group. There were no significant differences in single puncture time, inadequate diagnostic rate, malignant coincidence rate, and complication rate between the two groups (P > 0.05), while the experimental group was less than the control group in the frequency and total time of puncture, and the difference was statistically significant (P < 0.05).

Conclusions

Sonic division assisted non-coplanar puncture is an important supplement to FNAB of thyroid nodules, which can increase the success rate of puncture and shorten the total puncture time.
