Evolution of transbronchial needle aspiration - a hybrid method

Area of Science:

• Pulmonology
• Interventional Pulmonology
• Medical Education

Background:

• Conventional Transbronchial Needle Aspiration (C-TBNA) is an established diagnostic technique but faces underutilization.
• The advent of Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA) has revitalized interest in TBNA.
• Inadequate training in C-TBNA hinders its effective application and competitive edge.

Purpose of the Study:

• To share a junior pulmonary fellow's learning experience with C-TBNA.
• To summarize indications, anatomy, instruments, and techniques for C-TBNA.
• To propose improvements for current C-TBNA practices and outline its future.

Main Methods:

• A systematic training program incorporating slide presentations, video demonstrations, and hands-on practice with a bronchial tree model.
• Development and description of a novel hybrid C-TBNA method inspired by EBUS-TBNA principles.
• Focus on successful lymph node puncture at various stations.

Main Results:

• The described training program enabled successful puncture of lymph nodes across different stations.
• The novel hybrid C-TBNA method demonstrated potential for increased reliability and dependability.
• The study highlights the importance of structured training for C-TBNA proficiency.

Conclusions:

• Systematic training is crucial for mastering C-TBNA and ensuring its effective utilization.
• A hybrid C-TBNA technique offers a promising advancement for improving procedural outcomes.
• Further development and adoption of improved C-TBNA methods are essential for its future.
