2 Approach to Flat Lesions Approaching the lesion, we place the tip of the hood lightly against the non-lesion mucosa and look for the lesion demarcation line (DL) under low magnification (Fig. 12). Once the DL has been identified, we increase the magnification, and with the tip of the hood in contact with the non-lesion mucosa, aspirate intragastric air to draw the mucosa up into close contact with the hood (Fig. 13). This is the best tip for obtaining images in focus at the maximal magnifying ratio.

Muto et al. 1 Magnifying Image of Normal Esophageal Mucosa A schematic drawing of the superficial vascular network of the normal esophageal mucosa and submucosa is shown in Fig. 9 [1]. With a non-magnifying endoscope, as we draw close to the normal mucosa, we can discern the branching vascular network. Most of this network is located immediately above the muscularis mucosae. The intraepithelial papillary capillary loops (IPCLs), rising perpendicularly from the branching vascular network, are rarely discernible during non-magnifying examinations.

The recent advent of NBI has enabled us to distinguish ICPLs even more clearly as brownish dots. With M-NBI, the esophageal superficial vascular network appears green and the ICPLs as brownish looping lines. Intraepithelial papillary capillary loops (IPCLs) can be seen within the epithelial papillae. 2 Use of the IPCL Pattern Classification in Evaluation of the Endoscopic Degree of Atypia In regions with squamous epithelium, such as the pharynx and esophagus, with magnifying endoscopy, we can evaluate the endoscopic degree of atypia of a lesion through observation of changes in the IPCL pattern (Fig.
