Two types of confocal endomicroscopy systems are currently available in the United States. A mini-probe based system (MaunaKeaTechnology, France; upper panel) can be used through the working channel of most conventional endoscopes. In the confocal laser endomicroscope (Pentax, Japan; lower panel), the laser scanner is integrated into the endoscope. Reprinted with permission from Goetz M, Kiesslich R [33].
