Clinical Trial Summary

We plan the study to explore the application of endoscopic laser speckle imaging and multispectral blood oxygen imaging to observe gastrointestinal lesions, as well as the differences in the morphology, density and functional status of mucosal surfaces and deep blood vessels of different gastrointestinal lesions, also to explore the role of endoscopic multimodal functional imaging in common gastrointestinal diseases, especially in the early diagnosis of gastrointestinal tumors.

Description:

The current focus of electronic endoscopy is on the morphology and fine structure of the mucosal surface, and there is no effective observation method for the deep structure of the mucosa and the function of blood oxygen binding. However, the multilayer morphology and functions of mucosal vessels under different conditions of digestive tract lesions should be different. Therefore, we propose a method of endoscopic multimodal functional imaging to the conventional endoscopic examinations observing the mucosa of the digestive tract, which is based on the existing electronic endoscope, laser speckle contrast imaging and multispectral blood oxygen imaging technology. Laser irradiation was given to obtain the information of coherent light on the mucosal surface and deep scattering of coherent light to obtain multi-level vascular distribution information, and multispectral irradiation imaging was carried out to obtain the oxygenation situation of the mucosa. Finally, we may find the differences of images of deep blood vessels among common gastrointestinal diseases, which could help us to make early diagnosis of gastrointestinal tumors noninvasively.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Image quality rate	The main evaluation index (image quality rate) is based on FAS(Full Analysis Set) and PPS(Per Protocol Set), for statistical description. Image quality rate Calculation formula: image excellent rate = number of cases with excellent or good image quality evaluation ÷ number of subjects undergoing multimodal endoscopy × 100%.	one year
Secondary	Diagnosis accuracy according to image	(1) Endoscopy examinations combined with laser speckle imaging and Doppler blood oxygen imaging can realize multi-level vascular observation and photographing of the mucosa, and the imaging analyzer will analyzes and synthesizes the two-dimensional map of laser speckle and blood oxygen imaging of the mucosa. Endoscopist will make diagnosis according to the image they get. (2) After endoscopic biopsy or endoscopic mucosal resection (EMR), endoscopic submucosal resection (ESD) obtaining tissue specimens, the pathology was observed by conventional HE staining or immunohistochemistry. (3) The results of comparison are divided into conformity, partial conformity and non-conformity.	one year
