Summary: Based on systematic review and network meta-analysis, it was found that CADe has a higher detection rate for colorectal neoplasia compared to other techniques (such as chromoendoscopy or tools that increase mucosal visualization), supporting greater incorporation of CADe strategies into community endoscopy services.

Summary: Narrow-band imaging (NBI) is an optical digital enhancement method that allows the observation of vascular and surface structures of colorectal lesions. Despite some issues in earlier models, NBI has evolved and the newest endoscopic platform offers significantly brighter and detailed images. Increased visualization and universal compatibility across all scopes are expected to improve the detection and diagnosis of polyps and promote global standardization. Knowledge of NBI and magnifying colonoscopy will become essential for future endoscopic practice.

Summary: This study compared the effectiveness of LCI and NBI in detecting colorectal SSLs, and found no significant difference between the two methods. Both LCI and NBI were equally effective in detecting polyps and adenomas. Factors associated with SSL detection were bowel preparation score, withdrawal time, and operator experience.

Summary: This study investigated the diagnostic yields of brown slits for adenomas. The results showed that brown slits had high sensitivity, specificity, and accuracy for adenoma diagnosis, making it an effective method for diagnosing colorectal adenomas.

Summary: Computer-assisted detection (CADe) is a promising technologic advance that enhances adenoma detection during colonoscopy, but its role in reducing missed colonic lesions is uncertain. This study found that CADe can improve the detection rates of proximal adenomas and polyps, but may not reduce the number of missed proximal colonic lesions.

Summary: This meta-analysis demonstrates that Endocuff-assisted colonoscopy is associated with a significant improvement in adenoma detection rate and polyp detection rate compared to standard colonoscopy.

Summary: In this study, the use of improved narrow-band imaging (190-NBI) was associated with a lower adenoma detection rate (ADR) compared to high-definition white light colonoscopy (HD-WLC). However, this difference was only observed in inexperienced endoscopists. Therefore, more intensive training should be provided before implementing 190-NBI technology in daily clinical care.

Summary: Meta-analysis of randomized controlled trials (RCTs) showed that dye-based chromoendoscopy (DBC) increases key quality parameters in colonoscopy, supporting its use in everyday clinical practice.

Summary: Linked color imaging is significantly superior to white light imaging in terms of mean adenoma number per patient, and performs better in detecting small polyps.

Summary: The study showed that the sensitivity of NBI during flexible endoscopy was comparable to WLI during rigid endoscopy, with higher tumor extension observed using NBI. NBI during flexible laryngoscopy led to upstaging and downstaging of T classification, improving visualization of tumor extension and accuracy of staging.

Summary: This study found that colonoscopies performed by surgeons or other endoscopists were associated with poorer quality metrics and outcomes compared with those performed by gastroenterologists, suggesting targeted quality improvement efforts may be warranted.

Summary: A prospective randomized study was conducted on 138 patients with suspicious SSA, finding that NBI was not superior to WLE in detecting remnant SSA tissue after EMR and could not decrease the proportion of incomplete resection of SSA.

Summary: Compared with white-light colonoscopy, linked colour imaging showed improved performance in detecting flat-type colorectal polyps, significantly increasing adenoma and polyp detection rates, especially in the detection of polyps in the right colon.

Summary: Based on a systematic review of multiple meta-analyses, this study concludes that artificial intelligence-aided colonoscopy (AIC) is superior to conventional colonoscopy (CC) in the detection of polyps and adenomas, especially in terms of polyp detection rate and adenoma detection rate.

Summary: In the evaluation of non-polypoid colorectal lesions, the use of TXI showed improved visibility and color difference compared to WLI. However, NBI still had comparable performance. TXI may be effective in improving polyp detection.
