[ Summary ] |
It is important for us to pay attention to and diagnose the high degree of nuclear enlargement and multilayered nuclei findings in addition to the form of the glandular lumens for the endocyto (EC) diagnosis of depressed-type tumors. In addition, the fine granular structures in the EC image may correlate with the desmoplastic reaction of the invasive cancer; therefore, future studies to clarify these points are necessary. Furthermore, there is a possibility that the morphological types of colorectal tumors have a considerable effect on the precision of EC diagnosis because EC diagnosis must contact the scope tip with the surface of the lesion. In our retrospective study, there was no significant difference in the accuracies of pit pattern and EC diagnosis. However, there was a significant difference in the results of the protruding type and LST-NG, respectively, and it is required that we achieve a better sense of the characteristics of EC diagnosis and effectively combine it with the pit pattern diagnosis in the clinical cases. |
