“…The result that BLI and LCI improved the detection of colorectal lesions compared with WLI has been described in previous RCT. 9,11,12 In the present study, we adopted the eye-tracking system to assess the detection of colorectal lesions, and our result was consistent with that of previous RCT. There was no difference in the miss rate and detection time of colorectal lesions between BLI-bright and LCI in our study.…”

“…Third, most of the assessed lesions were flat lesions less than 5 mm. Previous reports demonstrated that significantly higher numbers of diminutive (less than 5 mm) colorectal lesions were detected by using BLI, and that colonoscopy using LCI detected significantly more flat lesions than WLI . It cannot be denied that such “lesion bias” influenced the result of the detection between IEE and WLI.…”

“…10 LCI images are reported to improve the detection of gastrointestinal neoplastic lesions compared to WLI. 11,12 No randomized controlled trial (RCT) has investigated whether BLI-bright or LCI is more useful for the detection of colorectal lesions. In some recent studies, improvement of visibility with LCI compared to BLI-bright has been reported.…”

Background and Aim To assess the visibility of colorectal lesions using blue laser imaging (BLI)‐bright and linked‐color imaging (LCI) with an eye‐tracking system. Methods Eleven endoscopists evaluated 90 images of 30 colorectal lesions. The lesions were randomly selected. Three images of each lesion comprised white light imaging (WLI), BLI‐bright, and LCI in the same position. Participants gazed at the images, and their eye movements were tracked by the eye tracker. We analyzed whether the participants could detect the lesion and how long they took to detect the lesion. We assessed the miss rate and detection time among the imaging modalities. Results One endoscopist was excluded, and 10 endoscopists were assessed. Overall, 12.6% of lesions were missed with WLI, 6.0% with BLI‐bright, and 4.3% with LCI; the miss rate of BLI‐bright and LCI was significantly lower than that of WLI (P < 0.01), with no significant difference between the former modalities (P = 0.54). Mean (± SD) detection times were 1.58 ± 1.60 s for WLI, 1.01 ± 1.21 s for BLI‐bright, and 1.10 ± 1.16 s for LCI. Detection time for BLI‐bright and LCI was significantly shorter than that for WLI (P < 0.0001), with no significant difference between the former modalities (P = 0.34). Regarding the miss rate and detection time between the expert and the non‐experts, there was a significant difference with WLI but not with BLI‐bright and LCI. Conclusion Blue laser imaging‐bright and LCI improved the detection of colorectal lesions compared with WLI using an eye‐tracking system.

“…Linked color imaging (LCI) is a new IEE method, with a laser light source to enhance slight differences in mucosal color, improving the ability to detect mucosal inflammation or atrophy and premalignant changes. LCI has been recently applied to detect early gastric cancer and colorectal polyps or flat lesions . Dohi et al .…”

Important progress is being made in endoscopic methods which allow clinicians to predict the presence of Helicobacter pylori based on characteristics of gastric mucosa and to obtain targeted biopsies. There are also important developments in molecular methods with various techniques derived from standard PCR, applied both on gastric biopsies and stool specimens. Progress is being made in microfluidic systems to get a reliable diagnosis in a very short time. The interest of the C urea breath test has been confirmed as well as stool antigen tests. Attempts are being made to find biological markers of premalignant conditions by serology, other than pepsinogens.

Detection of colorectal lesions during colonoscopy

Owing to its high mortality rate, the prevention of colorectal cancer is of particular importance. The resection of colorectal polyps is reported to drastically reduce colorectal cancer mortality, and examination by endoscopists who had a high adenoma detection rate was found to lower the risk of colorectal cancer, highlighting the importance of identifying lesions. Various devices, imaging techniques, and diagnostic tools aimed at reducing the rate of missed lesions have therefore been developed to improve detection. The distal attachments and devices for improving the endoscopic view angle are intended to help avoid missing blind spots such as folds and flexures in the colon, whereas the imaging techniques represented by image‐enhanced endoscopy contribute to improving lesion visibility. Recent advances in artificial intelligence‐supported detection systems are expected to supplement an endoscopist's eye through the instant diagnosis of the lesions displayed on the monitor. In this review, we provide an outline of each tool and assess its impact on the reduction in the incidence of missed colorectal polyps by summarizing previous clinical research and meta‐analyses. Although useful, the many devices, image‐enhanced endoscopy, and artificial intelligence tools exhibited various limitations. Integrating these tools can improve their shortcomings. Combining artificial intelligence‐based diagnoses with wide‐angle image‐enhanced endoscopy may be particularly useful. Thus, we hope that such tools will be available in the near future.
