Improving accuracy in percutaneous lung puncture using thoracic respiratory synchronization and laser angle guidance

Area of Science:

• Medical Imaging and Interventional Radiology
• Pulmonary Medicine
• Surgical Techniques

Background:

• Percutaneous lung puncture is crucial for diagnosing pulmonary nodules but faces accuracy challenges.
• Conventional methods may lead to suboptimal outcomes and increased complications.
• Improving precision in minimally invasive lung procedures is an ongoing area of research.

Purpose of the Study:

• To evaluate the effectiveness of matching thoracic respiratory activity and laser guidance in percutaneous lung puncture.
• To compare the accuracy and complication rates of this novel technique against conventional methods.
• To determine the feasibility of enhancing percutaneous lung puncture accuracy.

Main Methods:

• A retrospective case-control study involving 277 patients with pulmonary nodules.
• Patients were divided into three groups: conventional puncture, laser guidance, and thoracic respiratory activity matching (Ram).
• Data on puncture accuracy, CT scans, procedure time, and complications were analyzed.

Main Results:

• The thoracic respiratory activity matching group demonstrated a higher rate of reaching the target on the first puncture (67.05%) compared to the laser group (37.63%) and conventional group (23.96%).
• The Ram group also showed significantly reduced procedure times and fewer required CT scans.
• Complication rates were sequentially lower in the Ram group, though not statistically significant (7.95%).

Conclusions:

• Matching thoracic respiratory activity, particularly with laser guidance, significantly enhances percutaneous lung puncture accuracy.
• This technique reduces the number of interventions and procedure duration, potentially lowering complication risks.
• The straightforward nature of this method warrants further investigation in larger prospective trials.
