Abstract

Introduction

Sampling of non-palpable thyroid nodule under ultrasound guidance has been widely used, however less studies done in comparing the efficacy of technique between fine needle aspiration cytology (FNAC) and fine needle capillary sampling (FNCS) under ultrasound guidance.

 

Objectives

This study aimed to determine the cytologic adequacy rates and sample quality obtained by both techniques under ultrasound guidance.

 

Methods

Ultrasound‐guided thyroid nodule samplings were performed on 88 patients, 44 of them had FNAC and another 44 FNCS technique. The slides obtained were scored using a predetermined scoring system comparing five parameters: background blood; amount of cellular material; appropriate architecture retention, degree of cellular degeneration and cellular trauma. The results were analysed using chi square and binary logistic regression test.

 

Results

Patient who underwent FNCS technique was 0.61times (95%CI) less likely to have large amount of background blood sample; 0.39times less likely to have sample with excellent architecture retention; 2.31times and 1.13times more likely to have sample with minimal cellular degeneration and minimal cellular trauma respectively when compare to FNAC. These were however not statistically significant. FNCS was 0.23times less likely to obtain sample with abundant cellular material compared to FNAC and it was statistically significant. Diagnostic adequacy rate was similar in both techniques and it was statistically significant.

 

Conclusions 
Ultrasound‐guided FNAC and FNCS yielded comparable diagnostic adequacy rates. Our study did not prove a clear superiority of FNCS over FNAC or vice versa. Both techniques could be use in tandem to achieve better diagnostic accuracy.
