Advanced AI for Bronchoscopy Image Recognition
This study successfully developed an AI-based software utilizing YOLOv8 artificial neural networks for real-time recognition of key tracheobronchial structures. The model was trained on 3900 frames extracted from 130 minutes of bronchoscopy videos of a high-fidelity manikin. Data augmentation techniques, including rotations, zoom, translations, and noise addition, were employed to enhance robustness and balance the dataset. The model achieved an average precision-recall AUC of 0.98 and a mean average precision (mAP) of 0.98, demonstrating high accuracy in identifying anatomical landmarks, crucial for flexible bronchoscopy guidance.
Randomized Trial: AI-led vs. Human-led Training
A randomized controlled trial was conducted with 22 second-year anesthesia residents with limited bronchoscopy experience. Participants were divided into two groups: one receiving AI-based unsupervised training (n=11) and the other traditional human-led training (n=11). Both groups underwent 20 minutes of individual training using the AI software or an expert instructor. Bronchoscopy skills were assessed using a modified Bronchoscopy Skill and Task Assessment Tool (BSTAT) before and after training. Both groups showed significant improvement in BSTAT scores (from 30±4 to 53±2, p<0.001) and a reduction in procedural time (from 217±44 to 101±23 seconds, p<0.001), with no significant differences found between the AI-based and expert-led groups.
Enhancing Medical Training and Patient Safety
The developed AI software offers a viable tool for unsupervised medical training in flexible bronchoscopy, addressing the challenge of limited expert trainers and the risks associated with less experienced clinicians. Its real-time guidance capabilities can enhance procedural accuracy and potentially reduce complication rates in critical care settings. Future work involves training the system with human bronchoscopy videos, including both physiological and pathological images, to broaden its applicability and improve navigation software for real clinical use, similar to AI applications in ECG and MRI. The long-term retention of skills and the ideal blend of AI and human instruction remain areas for further investigation.
Study Limitations and Generalizability
Key limitations include the AI software's specificity to the manikin model used, limiting broader applicability until retrained with human images. The study's relatively small sample size (22 residents) and assessment only at Kirkpatrick level 2 (knowledge and skills acquisition) mean the clinical impact and long-term retention of skills require further evaluation. Additionally, the use of a simplified BSTAT version might have introduced a ceiling effect, potentially masking subtle performance differences. Lastly, the current AI was trained only on main tracheobronchial structures, not segmental bronchi.

Case Study: AI-Driven Bronchoscopy Training in Critical Care
This study highlights the successful development and validation of an AI-based image recognition software for flexible bronchoscopy. Deployed in a randomized controlled trial with intensive care residents, the AI system provided real-time guidance during simulation-based training. Crucially, the AI-led unsupervised training achieved comparable improvements in resident skills and procedural efficiency as traditional human-led instruction. This demonstrates a significant step towards scalable, effective, and unsupervised medical training solutions, enhancing both resident competence and ultimately, patient safety in critical airway management scenarios.
