Study Procedure and Outcomes
Patients presented 24 hours prior to surgery for intravenous infusion of 5mg/kg ICG (Akorn Pharmaceuticals, Illinois, USA). At the time of TORS, an endoscope attachment was used for primary tumor evaluation under white light. Tumors were coded yes/no for visualization under white light based on the surgeon’s impression. The primary lesion was then imaged using both the systems. Videos of tumor resection were recorded and analyzed postoperatively. Cases were evaluated for the presence/absence of NIR signal and tumor margin delineation as visualized by the two platforms.
