The Pinpoint System

  • Jana L. Lewis

Abstract

The Pinpoint system, an endoscopic real-time fluorescence imaging system, incorporates both a high definition (HD) white light and near infra-red (NIR) fluorescence excitation and acquisition systems into a single camera head. The standard white light view and NIR are thus retained throughout the procedure enabling the surgeon to operate with real-time fluorescence guidance. Our group has concentrated on the use of Pinpoint in the assessment of colorectal perfusion and intraoperative cholangiography. In addition, we describe our early experience using Pinpoint for sentinel lymph node dissection in colorectal and gastric malignancies and discuss future applications of this technology.
