Abstract

Endobronchial ultrasound guided transbronchial needle aspiration (EBUS TBNA) is performed by using special bronchoscope which has an ultrasound probe at its tip that could demonstrate lymph node outside the airway and allow for real time observation of transbronchial needle aspiration. The sensitivity and specificity of EBUS TBNA are high in many studies. However because of the high expense and special training required, the impact of this method on clinical practice guidelines (CPG) needs to be further evaluated. The patients were classified to three groups. Group One included proven lung cancer patients who do not have distant metastasis and no mediastinal lymphadenopathy as demonstrated by computer tomography. Group Two was the same as group One except there was evidence of mediastinal lymphadenopathy. The Third Group included patients who only had mediastinal lymphadenopathy without lung lesion. All lymph node stations were examined by EBUS and their sizes were recorded. Selected puncture of a lymph node was done and tissue was sent for cytological examination. There was no rapid on site cytologic examination. The impact on CPG was calculated from the number of patients who be prevented from mediastinoacopy. There were 158 ...Continue Reading
