Optimal band imaging system: a new tool for enhancing the duodenal villous pattern in celiac disease.
Gastrointest Endosc. 2008 Aug; 68(2):352-7.GE

Abstract

BACKGROUND

The optimal band imaging (OBI) system is a new technology that can select better spectral images decomposed from ordinary endoscopic images. This technology, first introduced as "FUJI Intelligent Color Enhancement," enhances the contrast of the mucosal surface without the use of dyes.

OBJECTIVE

This study aimed to evaluate the potential of OBI for predicting the duodenal villous morphologic characteristics in patients with suspected celiac disease.

DESIGN

This study was designed as an open, prospective, single-center trial. Duodenoscopy was performed with a high-resolution magnification view, in association with OBI spectral processing. Duodenal villous patterns were evaluated and classified as normal, partially atrophic, or markedly atrophic. The endoscopic results were then compared with the histologic diagnosis.

SETTING

Endoscopy unit at the A. Gemelli University Hospital of Rome, Italy.

PATIENTS

Sixty-one patients undergoing upper endoscopy for clinical history of malabsorption or serologic suspicion for celiac disease were included in the study.

RESULTS

From OBI sets using red, green, and blue wavelength combinations that ranged from 400 to 580 nm, the endoscopist was able to find marked villous atrophy of the duodenum in 16 subjects, partial villous atrophy in 9 subjects, and normal villi in the remaining 36 subjects. The sensitivity, specificity, and positive and negative predictive values of the OBI-based duodenoscopy were 100% accurate in the evaluation of villous patterns.

CONCLUSIONS

High-resolution magnification endoscopy with OBI allows clear visualization of the duodenal villous pattern. The OBI system may play a potential role in optimizing the diagnostic accuracy of endoscopy in celiac disease.
