Narrow-Band Imaging in Digestive Endoscopy

Use of narrow band imaging in a group endoscopy practice

BACKGROUND AND STUDY AIM Narrowband imaging (NBI) is an enhanced endoscopic optical technique which filters white light and accentuates imaging of the mucosal vasculature. Potential clinical applications of NBI include endoscopic inspection of Barrett's esophagus and endoscopic diagnosis of colorectal polyps. The degree to which NBI use has been adopted into clinical practice is unknown. The st...

Magnifying endoscopy with narrow-band imaging for gastric heterotopic pancreas

Background and study aims  Heterotopic pancreas is a common subepithelial lesion in the stomach. However, its histological diagnosis is difficult when tissue samples are obtained with a conventional biopsy forceps. This study aimed to describe the magnifying endoscopy with narrow-band imaging (ME-NBI) features of gastric heterotopic pancreas. Patients and methods  We retrospectively analyzed ...

Magnifying endoscopy findings in follicular lymphoma of the rectum using narrow band imaging.

Unique findings on endoscopy with narrow-band imaging in colonic lesions of Henoch-Schönlein purpura.

A 61-year-old woman presented with acute lower abdominal pain, bloody diarrhea, and purpura on the right thigh (●" Fig.1). Urgent sigmoidoscopy revealed edema and multiple hyperemic ecchymotic lesions in the sigmoid colon and rectum (●" Fig.2), which appeared reddish on viewing with conventional white light and cyan on narrow-band imaging (NBI) (●" Fig.3). These lesions were indicative of bleed...

Simplified Classification of Capillary Pattern in Barrett Esophagus Using Magnifying Endoscopy With Narrow Band Imaging

The classification of Barrett esophagus (BE) using magnifying endoscopy with narrow band imaging (ME-NBI) is not widely used in clinical settings because of its complexity. To establish a new simplified available classification using ME-NBI.We conducted a cross-sectional study in a single-referral center. One hundred eight consecutive patients with BE using ME-NBI and crystal violet (CV) chromo...
