Comparative Application of 5 mL Syringe and 22G PTC Needles in Thyroid Nodule Fine-Needle Aspiration

This study aims to compare the differences in sampling satisfaction rates between 5 mL syringe and 22G percutaneous transhepatic cholangiography (PTC) needles fine-needle aspiration (FNA) provide economical reasonable needle selection. From January 2021 March 2022, 187 patients with thyroid nodules (a total of 200 nodules) who underwent ultrasound-guided FNA were punctured using PTC once for each nodule, sample was sent pathological examination. The rate two methods statistically analyzed, factors affecting determined. Results demonstrated that overall syringes 83% 85% ( P >0.05), respectively. specimens 92.6% 91.1% P> 0.05) among 136 poor blood supply. For 64 rich supply, both significantly lower than nodule supply <0.05), latter (62.5% vs. 71.8%, <0.05). results suggest satisfactory can be obtained either a or needles. is more likely yield if
