[Transbronchial needle aspiration in routine bronchoscope practice].

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Diagnostic Bronchoscopy

Context:

• Transbronchial needle aspiration (TBNA) is a key diagnostic tool in pulmonology.
• Training in TBNA techniques is crucial for effective clinical practice.
• Computed tomography (CT) scanning offers precise guidance for endoscopic procedures.

Purpose:

• To assess the diagnostic yield of transbronchial needle aspiration (TBNA) in routine clinical practice.
• To evaluate the effectiveness of CT-guided training for TBNA procedures.
• To compare the efficacy of CT-guided TBNA with direct CT-guided lymph node aspiration.

Summary:

• This study evaluated 100 patients undergoing diagnostic fiberoptic bronchoscopy with 152 enlarged mediastinal lymph nodes.
• The CT-guided TBNA system achieved a positive yield of 64%, which was comparable to direct CT-guided aspiration (61%).
• The Wang TBNA System, guided by CT, was used to target enlarged mediastinal lymph nodes.

Impact:

• CT-guided TBNA training significantly improves procedural learning and proficiency.
• TBNA, when guided by CT, demonstrates high diagnostic accuracy and is a valuable tool in routine bronchoscopy.
• This approach enhances the utility of bronchoscopy for diagnosing mediastinal lymphadenopathy.
