    Abstract:
    Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is recommended for the diagnosis of mediastinal lymph nodes by the American College of Chest Physicians guidelines; however, the guidelines state that this procedure should only be performed by a trained bronchoscopist. Complications related to needle malfunction during the EBUS-TBNA procedure have recently been reported. We herein describe a rare case involving the successful management of a needle breakage that occurred as an unusual complication of EBUS-TBNA. An 81-year-old male patient with a medical history of myocardial infarction was introduced to our institution to undergo an evaluation for mediastinal and right hilar lymphadenopathy on chest computed tomography (CT). We performed EBUS-TBNA in a 14×10 mm subcarinal lymph node station using a 22 G aspiration needle (NA-201SX-4022, Vizishot®, Olympus, Japan) for diagnosing and staging of the patient's lung cancer. After the second aspiration, we noticed that the needle tip was broken and that it was stuck in the right main bronchus. We immediately removed the broken needle tip from the right main bronchus by flexible bronchoscopy using an ID 8.5 mm tracheal tube without cuff inflation. The length of the needle tip was 13 mm and it was considerably bent. The EBUS scope did not suffer any apparent damage. The patient did not have any other procedure-related complications. Needle breakage during EBUS-TBNA is rare; however, inhaling or swallowing of a broken needle tip has the potential to cause serious complications. Bronchoscopists should therefore be aware of the possibility of needle breakage, which is an important complication during EBUS-TBNA.
