Magnifying endoscopy with novel image enhancement technology for gastrointestinal tumors.

Abstract

<h4>Background and aims</h4>A new magnifying endoscope system applying novel endoscopic image enhancement technology of spectral focused imaging (SFI) and versatile intelligent staining technology (VIST) has been developed. This study aimed to evaluate the technical feasibility and the utility of the detection and diagnosis of gastrointestinal tumors.<h4>Methods</h4>We retrospectively reviewed and analyzed the endoscopic images of 6 digestive tract lesions in 4 patients detected with a SonoScape magnifying endoscope (SonoScape Medical Corp, Guangdong, China). The demographics, endoscopic and histopathologic features, and outcomes of the cases were analyzed.<h4>Results</h4>By varying the imaging mode of SFI and VIST, we could obtain enhanced endoscopic images clearly revealing esophageal intraepithelial capillary loop, gastric microvascular and microsurface, and colorectal pit pattern. These images significantly improved the efficiency of clinical diagnosis and were consistent with pathologic diagnoses.<h4>Conclusions</h4>Our study demonstrated that a novel magnifying endoscope system using SFI/VIST may be useful for diagnosis of gastrointestinal tumors.
