In vivo confocal laser endomicroscopy of the human liver: a novel method for assessing liver microarchitecture in real time

2008

Background and study aims Confocal endomicroscopy is a unique novel tool for in vivo histology in humans. Due to limitations imposed by the form of the equipment and by sterilization workflows, its use has been limited to the gastrointestinal tract so far. We have developed a rigid miniaturized probe for confocal endomicroscopy of the human liver during laparoscopy. Patients and methods To assess the feasibility and potential clinical value of this new system (diameter 6.3 mm), 25 patients with liver disease were examined during routine minilaparoscopy under conscious sedation. Results Subsurface serial images (from surface to 250 microm) were generated in real time after fluorescein inject…
