Autofluorescence imaging and magnification endoscopy

Gastric microcarcinoids diagnosed with magnification endoscopy

A 55-year-old lady underwent upper gastrointestinal endoscopy due to dyspeptic symptoms. Endoscopy revealed a diminutive flat reddened lesion measuring less than 2mm which appeared as an erosion in the proximal gastric body and a second diminutive one in the distal part of the gastric body [Fig. 1a, b]. Magnification Endoscopy with and without Narrow Band Imaging demonstrated distinctly differe...

Autofluorescence endoscopy for the gastrointestinal tract

This review focuses on our basic study results and clinical experience of fluorescence endoscopy for the gastrointestinal (GI) tract. Collagen, which fluoresces in the green wavelength range, is one of the major sources of tissue autofluorescence (AF) and AF imaging systems are now available. With their use, however, it is important to take into account tissue changes other than, or in addition...

Microcarcinoid tumor diagnosed with high-resolution magnification endoscopy and narrow band imaging.

Gastric Hyperplastic Polyp Associated with Proliferation of Xanthoma Cells Observed by Magnification Narrow-Band Imaging Endoscopy

A case of gastric hyperplastic polyp with proliferation of xanthoma cells is reported. The patient was a 69-year-old man who visited our hospital for further evaluation of gastric polyps. Endoscopic examination of the upper digestive tract revealed multiple hyperplastic polyps in the gastric antrum. There was a pedunculated polyp with whitish yellow granules, 7 mm in diameter, arising from the ...

Narrow Band Imaging with Magnification Endoscopy for Celiac Disease: Results from a Prospective, Single-Center Study

In celiac disease (CD), the intestinal lesions can be patchy and partial villous atrophy may elude detection at standard endoscopy (SE). Narrow Band Imaging (NBI) system in combination with a magnifying endoscope (ME) is a simple tool able to obtain targeted biopsy specimens. The aim of the study was to assess the correlation between NBI-ME and histology in CD diagnosis and to compare diagnosti...
