Clinical Trial Summary

In the coming years, an increase in lung nodule resection is expected, particularly in Video-assisted thoracoscopic surgery (VATS). In some situations, it is necessary to use a device for locating these nodules. Meanwhile, the Cone Beam Computed Tomography (CBCT) is a tool whose use is constantly spreading.

Description:

The aim of this study is to evaluate the feasibility of using intraoperative CBCT to develop a new procedure for intraoperative localization of pulmonary nodules in video-assisted thoracoscopic surgery.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Assessment of CBCT	Ability to identify the lesion on CBCT images of unventilated lung. CBCT images are interpreted by 2 senior surgeons.	the day following the acquisition
Secondary	Feasibility of CBCT	Number of patient excluded because of an inability to achieve CBCT acquisition, whatever the reason.	At the end of the surgery
Secondary	Assessment of global image quality	Assessment of image quality is based on an "open label" interpretation of CBCT images by two senior surgeons who score images from 0 (uninterpretable) to 10 (same quality as CT images)	the day following the acquisition
Secondary	Assessment of image quality of lesions	Assessment of image quality depending on the type of lesion and their location. Interpretation of CBCT images are performed by two senior surgeons who score images from 0 (uninterpretable) to 10 (same quality as CT images)	the day following the acquisition
