“…Based on the various lesions, different spectral images will be selected (29), which can achieve the purpose of electronic virtual chromoendoscopy. Some researchers have used FICE to diagnose gastrointestinal lesions and received satisfactory results in the world (30)(31)(32). In this study, the best wavelength combinations that we selected were as follows: R=540 nm, G=490 nm, B=420 nm and R=550 nm, G=500 nm, B=470 nm, which could clearly show the lesions.…”

Background/Aims: Esophageal squamous cell carcinoma is a common malignant tumor in recent years, and the key for improving the survival rate is early diagnosis and treatment. Computed virtual chromoendoscopy with the Fujinon intelligent color enhancement (FICE) system was reported to improve visualization of neoplastic and nonneoplastic lesions in gastroscopy and colonoscopy. The purpose of this study was to evaluate the value of FICE in the diagnosis of early esophageal squamous cell carcinoma and precancerous lesions. Materials and Methods: Two hundred fifty-seven patients with suspicious lesions of the esophagus were examined successively by FICE, magnifying FICE, Lugol chromoendoscopy, and magnifying Lugol chromoendoscopy in the hospital. The lesions and the intrapapillary capillary loop (IPCL, microvessels at the surface of esophageal carcinoma) were observed and compared with the pathologic diagnosis that was regarded as the golden standard. Results: The positive rates of early esophageal squamous cell carcinoma were 92.6% and 88.9% as examined by FICE and Lugol chromoendoscopy (p>0.05), and 96.3% and 92.6% as examined by magnifying FICE and magnifying Lugol chromoendoscopy (p>0.05), respectively. The magnifying FICE could observe the IPCL of the esophagus clearly. Early esophageal squamous cell carcinoma and high-grade intraepithelial neoplasia were mainly type IV and type V. Low-grade intraepithelial neoplasia and esophagitis were type II and type III, and normal esophagus was type I; however, the observation of the IPCL by magnifying Lugol chromoendoscopy was not clear. Conclusion: Fujinon intelligent color enhancement and magnifying FICE are complements to Lugol chromoendoscopy and magnifying Lugol chromoendoscopy in the diagnosis of early esophageal lesions.

“…However recent advances with this procedure have been made, and a new endoscope (model EG-580NW, Fuji Film, Co.) were manufactured beginning in October 2011. This endoscope is a trans-nasal model that provides high-quality endoscopic images with a wide field view of (140°) and is equipped with the flexible spectreal imaging color enhancement (FICE) system, which is based on a spectral estimation technique by which the narrow bandwidth is obtained from white light images without optical filters [13][14]. Unfortunately, the FICE system cannot image distinctive microvessels on the tumor surface as sharply as NBI.…”

“…The outer diameter of the endoscope is 5.9 mm. This endoscope is a trans-nasal model that provides high-quality endoscopic images with a wide field view (of 140°), and is equipped with the flexible spectral imaging color enhancement (FICE) system, which enhances images by extracting spectral images at the desired wavelengths via the application of signal processing to the white light generally used by endoscopes [13][14]. However, given the limited ability of conventional white light illumination to achieve high-cotrast imaging of microvessels in the mucosal surface layer, a more effective system was needed.…”

Purpose: We developed a new artificial image enhancement system aimed at intraoperative visibility improvement as a clinical prototype. We examined each optical characteristic and change in intraoperative visibility using brilliant blue G (BBG) staining with various sharp cut filters (SCFs). Method: This was a retrospective and observational study. The system was composed of several filters attached to the operating microscope. Six eyes from 6 patients who presented with macular hole and underwent surgery using this system were studied. As a clinical examination, the intraoperative visibility of BBG staining intensities was compared for 4 kinds of SCFs during vitrectomy. Quantitative evaluation was calculated using the International Commission on Illumination 1976 (L*, a*, b*) color space (CIELAB) method. Furthermore, we evaluated each optical characteristic of 4 types of SCFs using extracted porcine eyes and a spectroradiometer as a clinical simulation. Results: Suitable filter selection was possible for this system. The observed color tone and spectral irradiance changes with SCF insertion changed dynamically. In macular hole cases, the color intensities between BBG-stained and nonstained areas were improved using SCF-455 and SCF-520, which was statistically significant (p < 0.05) by CIELAB. Conclusion: The system improved BBG staining intensity with the use of selective SCFs.

Diagnosis of endoscopic Barrett’s esophagus by transnasal flexible spectral imaging color enhancement

Abstract: The transnasal FICE system enables clear visualization of palisade vessels and provides better contrasting images of the demarcation between the BE mucosa and the gastric mucosa, and thus contributes to easier diagnosis of endoscopic BE.
