| [ Summary ] |
Pit pattern analysis through use of magnifying chromoendoscopy (MCE) is considered to be a reliable tool for observation of colorectal lesions. On the other hand, some newly developed tools such as Narrow Band Imaging (NBI) systems and, endocytoscopes have expanded the choice of magnifying endoscopic techniques. To apply these tools and interpret clinical findings precisely, histopathological knowledge and sufficient experience with magnifying endoscopy are required. In addition, it should be kept in mind that the basic operational factor behind magnifying endoscopy is pit pattern analysis with MCE, from which todayʼs diagnostic tools heve been developed. NBI systems are among the most attractive tools in terms of worldwide reports of their diagnostic performance being equal to MCE. Moreover, it is expected that in the future we will be able to explore the possibilities of performing pit pattern analysis in regions where staining is difficult and it is hard to analyze pit patterns, or make predictions of lymphovascular invasion. |
