蓝激光内镜在消化道早癌精准诊断中的进展

目前消化道早癌的诊治已经是热点话题,其定义为病灶局限于黏膜层和黏膜下层的癌,包括早期食道癌、早期胃癌、早期结直肠癌。对于消化道早癌的诊断技术已经从单一的普通白光内镜,逐步过渡到色素内镜、电子染色窄带成像技术(NBI)、智能电子分光技术(FICE)、放大内镜和共聚焦光显微内镜(CLE)等,从而不断提高早期癌的检出率,甚至还能提供病变深度、范围和组织病理学等信息,而蓝激光内镜是来源富士公司推出的蓝激光内镜系统(LASEREO),为精准诊断消化道早癌带来更多可能性。该文就蓝激光成像技术(BLI)在消化道早癌精准诊断中的进展作一综述。

Advances in the accurate diagnosis of early carcinoma of digestive tract in blue laser endoscopy

At present, the diagnosis and treatment of early cancer in digestive tract is a hot topic, which is defined as cancer confined to the mucosa layer and submucosa, including early esophageal cancer, early gastric cancer and early colorectal cancer. For gastrointestinal cancer early diagnosis technology has been from a single common white light endoscopy, endoscopic gradually transition to the pigment dyeing narrow-band imaging technology, electronic (narrow band imaging, NBI), intelligent electronic spectroscopic techniques (flexible spectral imaging color enhancement, FICE), magnifying endoscopy, endoscopic confocal optical microscopy, confocal laser endomicroscopy, CLE), etc., so as to improve the early cancer detection rate, can even provide lesions in depth and scope, histopathology, and blue laser endoscope is introduced by the Fuji company blue laser endoscopic system (LASEREO), the more possibility for accurate diagnosis of early carcinoma of digestive tract. In this paper, the progress of blue laser imaging technology (blue laser imaging, BLI) in the accurate diagnosis of early carcinoma of digestive tract was overviewed.
