“…The combination of strong 410-nm laser light, weak 450-nm laser light, and fluorescent light enables blue laser imaging (BLI) via narrow-band light observation. Magnifying endoscopy with BLI (M-BLI) is useful for evaluating mucosal surface information such as surface blood vessel and structure patterns [13][14][15][16].…”

Background Blue laser imaging (BLI) is a new image-enhanced endoscopy technique that utilizes a laser light source developed for narrow-band light observation. The aim of this study was to evaluate the usefulness of BLI for the diagnosis of early gastric cancer. Methods This single center prospective study analyzed 530 patients. The patients were examined with both conventional endoscopy with white-light imaging (C-WLI) and magnifying endoscopy with BLI (M-BLI) at Kyoto Prefectural University of Medicine between November 2012 and March 2015. The diagnostic criteria for gastric cancer using M-BLI included an irregular microvascular pattern and/or irregular microsurface pattern, with a demarcation line according to the vessel plus surface classification system. Biopsies of the lesions were taken after C-WLI and M-BLI observation. The primary end point of this study was to compare the diagnostic performance between C-WLI and M-BLI. Results We analyzed 127 detected lesions (32 cancers and 95 non-cancers). The accuracy, sensitivity, and specificity of M-BLI diagnoses were 92.1, 93.8, and 91.6 %, respectively. On the other hand, the accuracy, sensitivity, and specificity of C-WLI diagnoses were 71.7, 46.9, and 80.0 %, respectively.Conclusions M-BLI had improved diagnostic performance for early gastric cancer compared with C-WLI. These results suggested that the diagnostic effectiveness of M-BLI is similar to that of magnifying endoscopy with narrow-band imaging (M-NBI).

“…At first, we perform a pre-check colonoscopy before ESD for the accurate diagnosis ( Figure 2A). Regularly, we adopt magnifying observation using narrow band imaging, blue laser imaging, and chromoendoscopy ( Figure 2B) (15)(16)(17)(18)(19). We also determine the status of manipulation about endoscope.…”

In Japan, endoscopic submucosal dissection (ESD) becomes one of standard therapies for large colorectal tumors. Recently, the efficacy of ESD has been reported all over the world. However, it is still difficult even for Japanese experts in some situations. Right-sided location, large tumor size, high degree of fibrosis, difficult manipulation is related with the difficulty. However, improvements on ESD devices, suitable strategies, and increase of operators' experiences enable us to solve these problems. In this chapter, we introduce recent topics about various difficult factors of colorectal ESD and the tips such as strategy, devices, injection, and traction method [Pocketcreation method (PCM) etc.].

“…BLI may be able to compensate for FICE because it uses narrow-band laser light combined with white light. Indeed BLI endoscopy has been shown to produce a new type of bright, high-resolution images of the digestive tract mucosa [9][10].…”

“…It is equipped with not only a white light observation but also a new narrow-band light observation function that takes advantage of the characteristics of laser light. Blue laser imaging observation (BLI) using the LASERIO system has successfully achieved a bright and clear image even at a distance [9][10]. In 2014, the EG-L580NW was released by Fuji film Corporation.…”

The ability of a novel blue laser imaging system for the diagnosis of invasion depth of colorectal neoplasms

Abstract: BLI magnification by laser source could predict histopathological diagnosis and invasion depth of colorectal neoplasms. The diagnostic effectiveness of this method was similar to that of NBI magnification.
