LungPoint--a new approach to peripheral lesions.

Area of Science:

• Pulmonology
• Medical Devices
• Diagnostic Imaging

Background:

• Flexible bronchoscopy has limitations in accessing peripheral lung lesions, especially those smaller than 30 mm or not visible on fluoroscopy.
• Peripheral lung lesions pose diagnostic challenges due to limitations in current bronchoscopic sampling techniques.

Purpose of the Study:

• To evaluate the utility of a novel bronchoscopic navigation system for accessing peripheral lung airways.
• To assess the system's effectiveness in enabling lesion sampling and diagnosis in patients with peripheral pulmonary lesions.

Main Methods:

• A pilot study utilized the LungPoint navigation system, generating virtual bronchoscopic pathways registered with real-time video.
• A thin bronchoscope was advanced to target peripheral lesions (<42 mm) under direct visualization, without fluoroscopy.
• Biopsies were performed on consecutive patients at a tertiary teaching hospital.

Main Results:

• The navigation system successfully guided the bronchoscope along the planned route in all 25 patients.
• The bronchoscope reached the target lesion bronchus in 56% of cases (14/25).
• A definitive diagnosis was achieved in 80% of cases (20/25) with minimal complications (one small pneumothorax).

Conclusions:

• The LungPoint navigation system demonstrates utility for bronchoscopic procedures targeting peripheral pulmonary lesions.
• This technology offers a promising approach to improve diagnostic capabilities for difficult-to-reach lung abnormalities.
