Digital processing of video-endoscopic images in esophagitis appears to be a useful method for quantifying mucosal color changes, with a potential to provide improved reproducibility in the follow up of individual cases and in comparison between patients and groups of patients. However, the sources of error such as type of equipment, the distance of the endoscope tip to the cardia, axial positioning of the endoscope in the esophagus, and the distance from the endoscope tip to the area of interest must be taken into account.
