The Comparison of Endobronchial Ultrasound-guided Transbronchial Needle Aspiration, Mediastinal Cryobiopsy Via a Tunnel, and Forceps Biopsy Via a Tunnel in Diagnosing Mediastinal Lymphadenopathy: a Multicenter Randomised Controlled Trial.
The goal of this prospective, multi-centre, randomised controlled clinical study is to compare the diagnostic yield and safety of the three biopsy techniques (EBUS-TBNA, EBUS-TBMC via a tunnel, and EBUS-TBFB via a tunnel) in mediastinal/hilar lymph node biopsies. Participants will divided into EBUS-TBNA group, EBUS-TBMC via a tunnel group, and EBUS-TBFB via a tunnel group at a 1:1:1 ratio by using central, computerized random sequence, and then undertake EBUS-TBNA, EBUS-TBMC via a tunnel, or EBUS-TBFB according to the group. Researchers will compare the diagnostic yield and incidence of adverse events of the three biopsy techniques.
• Age ≥ 18 years;
• At least 1 hilar/mediastinal lesion (short axis ≥ 1 cm) requiring diagnostic bronchoscopy procedure;
• Patients who can understand the purpose of the trial, participate voluntarily and sign an informed consent form.
