“…Moreover, LCI improved the visibility in diffuse redness, spotty redness, map‐like redness, patchy redness, red streaks, and an atrophic border compared with WLI, while BLI‐bright improved the visibility in intestinal metaplasia . In a cross‐sectional study for the risk of EGC after successful H. pylori eradication according to the Kyoto classification of gastritis using WLI and LCI, map‐like redness and the absence of RAC were associated with EGC after H. pylori eradication in multivariate analysis . LCI was more efficient for evaluating map‐like redness than WLI, because LCI could identify map‐like redness more frequently than WLI (Fig.…”

“…However, the total score of this grading system after H. pylori eradication therapy may not reflect the accurate risk of gastric cancer because of the disappearance of diffuse redness, nodularity, and enlarged folds. Furthermore, map‐like redness and the absence of RAC were identified as independent risks of gastric cancer after H. pylori eradication . Therefore, a new grading system, which includes the findings of mucosal atrophy, intestinal metaplasia, map‐like redness and RAC, will be required to determine a risk of gastric cancer in patients with past H. pylori infection.…”

Endoscopic diagnosis of Helicobacter pylori (H. pylori) infection, the most common cause of gastric cancer, is very important to clarify high-risk patients of gastric cancer for reducing morbidity and mortality of gastric cancer. Recently, the Kyoto classification of gastritis was developed based on the endoscopic characteristics of H. pylori infection-associated gastritis for clarifying H. pylori infection status and evaluating risk factors of gastric cancer. Recently, magnifying endoscopy with narrow-band imaging (NBI) has reported benefits of the accuracy and reproducibility of endoscopic diagnosis for H. pylori-related premalignant lesions. In addition to NBI, various types of image-enhanced endoscopies (IEEs) are available including autofluorescence imaging, blue laser imaging, and linked color imaging. This review focuses on understanding the clinical applications and the corresponding evidences shown to improve the diagnosis of gastritis based on Kyoto classification using currently available advanced technologies of IEEs.

Current status and future perspective of linked color imaging for gastric cancer screening: a literature review

et al. 2022

Screening endoscopy has advanced to facilitate improvements in the detection and prognosis of gastric cancer. However, most early gastric cancers (EGCs) have subtle morphological or color features that are difficult to detect by white-light imaging (WLI); thus, even well-trained endoscopists can miss EGC when using this conventional endoscopic approach. This review summarizes the current and future status of linked color imaging (LCI), a new image-enhancing endoscopy (IEE) method, for gastric screening. LCI has been shown to produce bright images even at a distant view and provide excellent visibility of gastric cancer due to high color contrast relative to the surrounding tissue. LCI delineates EGC as orange-red and intestinal metaplasia as purple, regardless of a history of Helicobacter pylori (Hp) eradication, and contributes to the detection of superficial EGC. Moreover, LCI assists in the determination of Hp infection status, which is closely related to the risk of developing gastric cancer. Transnasal endoscopy (ultra-thin) using LCI is also useful for identifying gastric neoplastic lesions. Recently, several prospective studies have demonstrated that LCI has a higher detection ratio for gastric cancer than WLI. We believe that LCI should be used in routine upper gastrointestinal endoscopies.
