Abstract

Image enhanced endoscopy (IEE) is a combination of different advanced endoscopic methods which help to provide optical real time diagnosis for the luminal lesions. Traditional biopsy may have a disadvantage of sampling error since biopsy usually provide a small portion of lesion except the total excisional biopsy provided by small advanced excisional technique e.g, endoscopic submucosal dissection. Methods for IEE in general included special lighting e.g, narrow band imaging or blue laser imaging, both optical or digital magnification, chromoendoscopy and endoscopic ultrasound. Although different sites in luminal tract will have differences in terms of interpretion of IEE. In general, the purpose of IEE is to provide an optical diagnosis for a specific lesion regarding of the nature of lesion i.e., benign or malignant, and if the lesion is likely to have malignant component, the information about the depth of invasion can be provided. The approach of IEE start with the macroscopic appearance of the lesion in term of the color, shape, surface, consistency. The surface pattern and vascular pattern under the special light or chromoendoscopy are then observed to provide more information of the nature of the lesion and depth of invasion. Endoscopic ultrasound can provide more details of the depth of invasion. Good quality IEE is a must before any endoscopic treatment for the luminal lesion especially in the era of endoscopic submucosal dissection for good case selection.
