Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
With the advances in screening technology for lung cancer tumours, an increasing amount of very small lung cancer tumours are being found, and the demand for segmentectomy is increasing. A segmentectomy is a hard surgery to perform robotically because it is difficult to view the tissue lines that separate each segment within the lobe. As a result, it is difficult for the surgeon to see exactly which pieces of tissue should be removed. Because of these challenges, many patients having robotic surgery will have a lobectomy, even if a full lobectomy is not needed.
Near-Infrared Fluorescence (NIF) using indocyanine green (ICG) fluorescent dye is a recent advancement in the robotic platform of robotic surgery. The surgeon will view the CT scan to determine which segment the tumour is located in. Once identified, the surgeon will isolate the segment by cutting off the blood supply to that segment. Then ICG will be injected into a vein. It is expected that the entire lung, except the isolated segment, which will remain 'dark' as it was isolated from blood supply, will fluoresce, giving off a green hue when viewed with the da Vinci Firefly camera. The surgeon will identify 'dark' segment, and will remove it. A pathologist will examine the excised tissue to ensure that the tumour was removed in its entirety. Once confirmed, the surgeon will end the procedure. If the pathologist determines that the segment removed did not contain the entire tumour, then the surgeon will perform a routine lobectomy. This ensures patient safety and confirms that all participants will have the entire tumour removed from their lung.

indocyanine green
Non-toxic, fluorescent dye
indocyanine green
ICG will be prepared as a sterile solution (2.5 mg/10mL) for injection. After vascular ligation, a 6 to 8mL bolus of ICG solution will be injected into the peripheral vein catheter, followed by a 10mL saline solution bolus. The Firefly camera will then be used for the NIF imaging. It is expected that the entire lung, except the segment which was previously isolated from blood supply, will fluoresce within 30-40 seconds, exhibiting a green hue. The surgeon will perform the pulmonary resection and the resected 'dark' lung segment will be immediately evaluated by a pathologist, depending on the pathologist findings the operation may be concluded or the patient will receive a pulmonary lobectomy.
