Comparison of PENTAX EB-1970UK and EB19-J10U ultrasound bronchoscopes for EBUS-TBNA in the diagnosis of mediastinal lymphadenopathy.

ABSTRACT:

Background and aim

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a widely used technique for evaluating mediastinal lymphadenopathy. However, limited data exist regarding the impact of different ultrasound bronchoscope models on procedural outcomes. This study assessed the technical performance, diagnostic efficacy, and safety of two PENTAX bronchoscopes-EB-1970UK and EB19-J10U-in EBUS-TBNA.

Patients and methods

This retrospective study included patients with mediastinal lymphadenopathy who underwent EBUS-TBNA at Shengjing Hospital, China Medical University between January 2023 and March 2024. Patients were divided into two groups based on the bronchoscope used: EB-1970UK (n=73) and EB19-J10U (n=75). The groups were compared for specimen ade
