Assessment of Cone-beam Computed Tomography (CBCT) Assistance to Video-assisted Thoracoscopic Surgery

Not Applicable
Completed
Conditions
Thoracoscopy
Interventions
Procedure: CBCT acquisition
Procedure: Anesthesia and surgery
Registration Number
NCT02966847
Lead Sponsor
Rennes University Hospital
Brief 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.

Detailed 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.

Primary Outcome Measures
NameTimeMethod
Assessment of CBCTthe day following the acquisition

Ability to identify the lesion on CBCT images of unventilated lung. CBCT images are interpreted by 2 senior surgeons.

Secondary Outcome Measures
NameTimeMethod
Feasibility of CBCTAt the end of the surgery

Number of patient excluded because of an inability to achieve CBCT acquisition, whatever the reason.

Assessment of image quality of lesionsthe day following the acquisition

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)

Assessment of global image qualitythe day following the acquisition

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)
