Clinical Trial Summary

The investigators will compare endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) with intranodal forceps biopsy (EBUS-IFB) as it relates to the rate of diagnosis of suspected sarcoidosis.


Description:

This is prospective, single center randomized comparative study to determine the diagnostic yield and specimen quality of endobronchial ultrasound guided intranodal forceps biopsy of patients with suspected sarcoidosis based solely on imaging. This will be a single group study and will compare transbronchial needle aspiration via 19 or 21-gauge needle with intranodal forceps biopsy. The study aims to answer a knowledge gap a as to whether the diagnostic yield and specimen quality of EBUS-TBNA with a 19G needle is less than those obtained by 1.9mm or greater intranodal forceps biopsy. The study proposed here will add to the field by further elucidating whether this procedure is beneficial for the diagnosis as it pertains to suspected sarcoidosis. The anticipated required enrollment is 55 patients to achieve an α of 0.05 and β of 0.2. This assumes an unassisted diagnostic yield of 62.5% with standard of care EBUS-TBNA as reported in Ray et al, and a diagnostic supplementation to 80% yield with intranodal forceps biopsies.

Study Design


Intervention

Procedure:
Endobronchial Ultrasound-Guided Intranodal Forceps Biopsy
Patients with mediastinal adenopathy will undergo EBUS-IFB and EBUS-TBNA during the same procedure to compare the yield of this procedure with EBUS-TBNA alone.
