Background: Optimal visualization of the operative field and methods that additionally provide supportive optical information form the basis for target-directed and successful surgery. This article strives to give an overview of current enhanced visualization techniques in visceral surgery and to highlight future developments. Methods: The article ...
A newly proposed classification by the European Laryngological Society (ELS) of glottic lesions by narrow-band imaging (NBI) divides their vascular patterns into longitudinal and perpendicular ones. The latter are further subdivided into the wide and narrow patterns. The longitudinal, wide, and narrow patterns are characteristic of benign disease, ...

Background/Aims: The diagnostic efficacy of magnifying blue laser imaging (M-BLI) and M-BLI in bright mode (M-BLI-bright) in the identification of early gastric cancer (EGC) was evaluated for comparison to that of magnifying narrow-band imaging (M-NBI). Methods: This prospective, multicenter study evaluated 114 gastric lesions examined using M-BLI,...

A 73-year-old woman underwent upper endoscopic screening that revealed a 30-mm superficial elevated lesion in the anterior wall of the upper gastric body. The lesion had a whitish color and coarse granular surface in conventional white light endoscopy. Magnifying narrow-band imaging indicated irregular microvascular and microsurface patterns within...

UC patients with morphological alterations in PPs were at high risk of clinical relapse. Therefore, to predict the clinical course of UC, it may be useful to evaluate NBI-ME images of PPs.

Background/Aims: We established a new colorectal T1 invasion depth sub-classification and evaluated it to determine whether total excisional biopsy can be performed on colorectal carcinoma (CRC) cases using narrow-band imaging (NBI) magnification. Methods: The cases included 73 T1 carcinomas selected from 173 early CRC cases. The T1 invasion depth ...

Biopsies are necessary for the management of duodenal tumors. However, the most suitable targets for biopsy are not known. An 82-year-old woman who regularly visited our hospital for rheumatoid arthritis underwent abdominal ultrasonography. This screening revealed a dilated pancreatic duct. Magnetic resonance cholangiopancreatography was performed,...

Background: Magnifying endoscopy (ME) with narrow-band imaging (NBI) can visualize a white opaque substance (WOS) in gastric epithelial neoplasms, gastric intestinal metaplasias, and colorectal epithelial neoplasms. Histological examination showed the WOS to be lipid droplets accumulated in the epithelium. The white appearance of colorectal hyperpl...
