ABSTRACT
Objective To explore the clinical value of untrasonographically guided fine needle puncture ab -sorbing cytology examination in the diagnosis of cervical lymph node tuberculosis .Methods In March 2013 to June 2015 454 cases of suspected cervical lymph node tuberculosis cases were selected , and 454 suspected cases according to the voluntary principle were divided into two groups : US -FNAC groups: 326 cases with US -FNAC detection;FNAC groups: 128 cases, using FNAC.Statistical degree of two groups of detection sensitivity , specific, positive predictive value, negative predictive value and accuracy , and follow -up of two groups of complications .Results In US -FNAC group 326 cases, after the US -FNAC tested positie 308 cases, 304 cases confirmed by pathology after true positive and false positive 4 cases, through US -FNAC tested negatie 18 cases, were confirmed by pathology af -ter true negative, 15 cases of false negative in 3 cases; FNAC in the group of 128 cases of FNAC tested positie 107 cases, 102 cases confirmed by pathology after true positive and false positive in 5 cases, by FNAC tested negatie 21 cases, 12 cases confirmed by pathology after really negative , 9 cases of false negative.US -FNAC, the sensitivity of the detection of cervical lymph node tuberculosis (99.02%) than FNAC (91.89%), the difference was statisti-cally significant (p 0.05); US -FNAC, the accuracy of the detection of cervical lymph node tuberculosis (95.30%) than FNAC (89.47%), the difference was statistically significant (p <0.05); US - FNAC, incidence of complications (1.23%) is lower than the FNAC group (4.69%), and the difference was statistically significant (chi -square =5.1095, p =5.1095,p <0.05). Conclusion US -FNAC is used for the diagnosis of cervical lymph node tuberculosis , and has the advantages of high sensitivity, high accuracy.So US -FNAC diagnosis in cervical lymph node tuberculosis suspected cases has the important clinical value.
