View an intraoperative assessment of gastric tube perfusion using both NIRF and iCertainty™.


Esophageal replacement can be indicated for cancer, strictures, perforation, lye ingestion, Barrett’s esophagus, recurrent trachea-esophageal fistulas, and achalasia.

Complications are not uncommon. In an article published in the peer-reviewed Allied Journal of Clinical Pathology Research,* researchers found that 63 percent of esophageal replacement cases experienced post-surgical complication — the most common being leakage, stenosis and poor vascularization.

The video above examines the use of Near-infrared fluorescence (NIRF) and RFPi’s iCertainty™ in evaluating the gastric tube in preparation for esophageal replacement.

During this surgery, NIRF imaging required the injection of ICG dye, which binds to blood proteins and over time circulates to the target the tissue of interest; with NIR illumination, ICG fluoresces in blood in tissues to illustrate perfusion in the gastric tube.

iCertainty™ is a novel non-invasive, no-injection, non-contact, non-ionizing technology solution recently cleared by the U.S. Food and Drug Administration. During this surgery, iCertainty™ images within 10 seconds blood flow and perfusion with real-time visualization and analysis.
