The clinical value of high frequency color ultrasound-guided biopsy in neck mass

Abstract

Objective To explore the biopsy success rate and safety of high frequency color ultrasoundguided biopsy in neck mass.Methods Four hundred and fifty cases of high frequency color ultrasound-guided biopsy in neck mass were analyzed retrospectively.According to histopathologic results,the biopsy success rate was discussed,and complications were recorded.Results ①Biopsy success rate was lower in smaller mass.Biopsy success rate of three groups were:86.27％ in group A(＜1cm),96.93 ％ in group B(1 ～ 2 cm),and 97.08％ in group C(＞2cm).There was significant difference between group A and group B(86.27％ vs 96.93％,x2= 7.818,P =0.005),and there was no significant difference between group B and group C (96.93％ vs 97.08％,x2 = 0.007,P = 0.933).②There was significant difference between 15 mm and 22 mm sample( 88.62％ vs 98.47％,x2= 21.457,P ＜ 0.001).③There was no significant difference between 16G and 18G needle(96.68％vs 94.41％,x2=1.368,P =0.242).④The complication was pain slightly in part of patients,and no severe complication was found.ConclusionHigh frequency color ultrasound-guided biopsy in neck mass is a safety,easy,inexpensive and minimally invasive sampling method.It can provide important information in the diagnosis and treatment of the neck mass.
