This will be a prospective, (NSR), single-center feasibility study of the Olympus VE2 NIR Imaging System to assess perfusion using NIR during minimally invasive esophagectomy and pulmonary segmentectomy. The aims of the study are: 1\. To utilize NIR intraoperative imaging with the Olympus VE2 NIR Imaging System to: i. Characterize gastric conduit perfusion during esophagectomy and, ii. Identify segmental anatomy during sublobar pulmonary resection (segmentectomy) after intraoperative, intravenous delivery of low-dose 0.15 mg/kg of ICG.
