PURPOSE: A transbronchial biopsy (TBB) using a radiographic fluoroscopy is one of the most generally accepted methods for diagnosing lung mass. However, it has disadvantages of excessive radiation exposure for patients and medical workers. The aim of this study was to compare the diagnostic yield of TBB between EBUS-GS without radiographic fluoroscopy and radiographic fluoroscopy guided examinations for lung mass.
METHODS: Patients with confirmed lung mass were included in this prospective, randomized study and assigned to undergo TBB and brushing under radiographic fluoroscopy or EBUS-GS without radiographic fluoroscopy.
RESULTS: A total of 46 patients were enrolled and randomized, of whom 41 patients (22 EBUS-GS without radiographic fluoroscopy; 19 radiographic fluoroscopy guided method) were included in the analysis. The diagnostic yield was not significantly different between the EBUS-GS without radiographic fluoroscopy method and the fluoroscopy guided method (59.1 vs. 63.2%, respectively; p = 1.0). The mean fluoroscopic time and radiation exposure dose was 81 seconds and 3.5 mGy respectively in the fluoroscopy guided group. There was no complication during the procedure in both groups.
CONCLUSIONS: The diagnostic yield of EBUS-GS without radiographic fluoroscopy was not different to conventional radiographic fluoroscopy method for the diagnosis of lung mass and reduced radiation exposure on patients and staff.
CLINICAL IMPLICATIONS: EBUS-GS without radiographic fluoroscopy can be an alternative technique used for diagnosis lung mass.
