Real-time margin assessment for video-assisted thoracic surgery: A pilot clinical trial.

ABSTRACT:

Objective

To accurately provide real-time intraoperative guidance on margins despite significant lung deformation. With lung cancer screening programs, smaller, early-stage lung nodules are being detected. Sublobar resection of peripheral small nodules is noinferior to lobar resection in terms of disease-free recurrence and long-term survival while preserving healthy lung function. However, accurately ensuring sufficient resection margin is challenging.

Methods

A novel navigation system with a tumor marker (J-bar), surgical stapler instrumented with a position sensor, and software to compute the distances in real time has been developed and utilized during surgery to resect lung cancer. The software measurement of the J-bar to the tip of the stapler cutline (J-bar-tip) was c
