3 Timing and Sequence of NBI Examination Immediately after NBI examination of the pharyngeal and laryngeal regions, we insert the endoscope into the esophagus, so we can see that continued use of NBI allows for a smoother procedure. During scope insertion, examination for the cervical esophagus (approximately 16–18 cm from the incisors) is difficult, so this region must be examined at the time of scope withdrawal. Accordingly, during scope insertion, examination commences approximately 18 cm from the incisors in the upper esophagus.

4S lesions correspond to LPM cancer, 4M to MM or SM1 cancers, and 4L to SM2 and SM3 cancers. Saucer-shaped lesions with raised edges form a surrounding area with stretched irregular vessels (SSIVs). The depth of invasion can be evaluated using the vessels enclosed by the SSIV; if they are type 3, it is type 4 around type 3 (ard 3), and if they are type 4, it is type 4 around type 4 (ard 4, Fig. 12f). On the other hand, non-AVA type 4R lesions that do not form an AVA are often poorly differentiated cancers that do not form a distinct tumor mass, lesions that exhibit infiltrative growth pattern c (INFc), or cancers of a specific histological type with fine honeycomb pattern of invasion.

In this section, we will examine the correlation between endoscopic images and anatomical subsites, with the emphasis on the hypopharynx. 2 Regional Classification of the Pharynx The pharynx is divided into the epipharynx (nasopharynx), mesopharynx (oropharynx), and hypopharynx (laryngopharynx), as shown in Fig.
