Intraoperative Navigation for Surgically Precise Resection of the Chest (INSPIRE)

Not Applicable

Recruiting

• Conditions: Thoracic Wall
• Interventions: Procedure: surgical navigation system

• Registration Number: NCT04328584
• Lead Sponsor: University Health Network, Toronto

Brief Summary

While undergoing chest wall resection, a surgeon's major concern is obtaining an appropriate surgical margin. Difficulty or failure to do so can result in prolonged operative time, need for re-operation due to a positive resection margin, or need for complex chest wall reconstruction due to unnecessarily wide resection. Over the last decades, surgical navigation systems have been developed to improve operative precision in various surgical fields. This is achieved by integrating patient images with intraoperative findings.

Detailed Description

Integration of CT imaging systems into the operating room now provide real-time 3D images of patient anatomy during surgery. This better adjusts for anatomical deformation and tissue excision compared to using preoperative images alone.

Twenty patients scheduled for chest wall resection will be enrolled over the study duration of 2 years. Patients will undergo imaging and surgery in the GTx-OR at Toronto General Hospital, as part of the GTx Program of the TECHNA Institute. All patients will be asked to consent to receiving their care in a research environment. They will also be asked to consent to having the intraoperative image acquired and used to generate a navigation view in the GTx-OR. Instead of resecting the chest wall lesion according to the preoperative images alone with intraoperative findings as per standard-care procedures, the navigation view will be used as an additional reference for surgeons during the operation.

Exclusion Criteria

1. Unresectable lesions or unstable patient condition, for which surgery is not recommended
2. Participants with metallic implantation, such as ribs fixations, a pacemaker, or pedicle screws, which may affect the accuracy of CBCT
3. Excluded at the discretion of the clinical investigator/surgeon, if they are enrolled in other studies that will result in combined radiation exposure exceeding standard of care
4. Pregnant, lactating, or planning to become pregnant during the period of the evaluation
