気管·気管支周囲病変に対する新たな生検法コンペックス走査式超音波気管支鏡ガイド下針生検

摘要

The convex-probe endobronchial ultrasound is a new ultrasound guided puncture bronchoscope that is used for endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) . EBUS-TBNA can be used for (a) lymph node staging in lung cancer patients ; (b) diagnosis of intrapulmonary tumors ; (c) diagnosis of unknown hilar and/or mediastinal lymphadenopathy ; and (d) diagnosis of mediastinal tumors. EBUS-TBNA is a novel approach that is safe and has a good diagnostic yield.
