Blue Laser Imaging with a Small-Caliber Endoscope Facilitates Detection of Early Gastric Cancer

Takahashi , Miura Y, Osawa H, Takezawa T, Ino Y, Okada M, Lefor AK, Yamamoto H

Conventional endoscopy often misses early gastric cancers with minimal red discoloration because they cannot be distinguished from inflamed mucosa. We treated a patient with a small early gastric cancer that...

Linked Color Imaging and Blue Laser Imaging for Upper Gastrointestinal Screening

Osawa H, Miura Y, Takezawa T, Ino Y, Khurelbaatar T, Sagara Y, Lefor AK, Yamamoto H

White light imaging (WLI) may not reveal early upper gastrointestinal cancers. Linked color imaging (LCI) produces bright images in the distant view and is performed for the same screening indications...

An Ultrathin Endoscope with a 2.4-mm Working Channel Shortens the Esophagogastroduodenoscopy Time by Shortening the Suction Time

Shinozaki , Miura Y, Ino Y, Shinozaki , Lefor AK, Yamamoto H

BACKGROUND/AIMS: Poor suction ability through a narrow working channel prolongs esophagogastroduodenoscopy (EGD). The aim of this study was to evaluate suction with a new ultrathin endoscope (EG-580NW2; Fujifilm Corp.) having...
