In-vivo microvascular imaging of early squamous-cell cancer of the esophagus by confocal laser endomicroscopy

Abstract

We present the case of a 63-year-old man with an early esophageal squamous-cell cancer that was visualized and analyzed by fluorescein-aided confocal laser endomicroscopic imaging. Our findings indicate that endomicroscopy is readily able to provide images of microvessels and to differentiate between normal and abnormal tumor vessels. Endomicroscopy therefore has the potential to characterize microvascular changes in early squamous-cell cancer, suggesting that this technique might have major implications for optimizing treatment strategies in modern endoscopy.
