Analysis of influencing factors on satisfaction of fine needle biopsy specimens of thyroid nodules / 中国医师杂志

ABSTRACT

Objective:To explore the influencing factors of satisfaction with thyroid nodule fine needle biopsy (FNA).Methods:The ultrasonic images of 88 patients with thyroid nodules (95 nodules) in Dongguan Binhai Bay Central Hospital from September 2016 to January 2019 were analyzed retrospectively. According to Bethesda cytological classification standard, Bethesda class Ⅰ cytological specimens were defined as unsatisfactory, and Bethesda class Ⅱ-Ⅵ cytological specimens were defined as satisfactory. The thyroid nodule location, composition, internal echo, morphology, aspect ratio, calcification, blood supply mode and American College of Radiology Thyroid Imaging Reporting and Data System(ACR TI-RADS) classification on the satisfaction rate of thyroid nodule FNA samples were evaluated, and then the meaningful influencing factors were analyzed by logistic regression.Results:The overall satisfaction of the sample in this study was 84.2% (80/95). The results of univariate analysis showed that the location, aspect ratio and ACR TI-RADS classification of thyroid nodules were the related factors affecting the satisfaction of FNA specimens of thyroid nodules, with statistically significant difference ( P<0.05). Logistic regression analysis showed that the aspect ratio of thyroid nodules was an independent factor affecting the satisfaction of FNA specimens of thyroid nodules ( OR=13.5, P=0.02). Conclusions:The main factor affecting the satisfaction rate of FNA specimens of thyroid nodules may lie in the characteristics of the aspect ratio of the nodules themselves. Optimizing the puncture route may help to reduce the dissatisfaction rate of FNA specimens of thyroid nodules.
