Summary: The study evaluated the effectiveness of Sound Speed Correction (SSC) in diagnosing colorectal neoplasms and determining the depth of invasion. Results showed that SSC can accurately differentiate between neoplasms and normal mucosa based on sound speed measurements, making it a potentially useful modality in clinical practice.

Summary: Lugol chromoendoscopy (LCE) is a technique for screening esophageal neoplastic lesions with high sensitivity but limited specificity. This study identified risk characteristics related to false-positive results for LCE, including vascular network, appearance, size, and color of the lesions.

Summary: The study evaluated the efficacy and safety of cap-assisted EMR for benign nonlifting colorectal polyps, finding that EMR-C can effectively remove polyp tissue and reduce recurrence rates, with deep mural injuries successfully treated with clips.

Summary: The multitarget stool DNA test (sDNA-FIT) is recommended as an option for colorectal cancer screening, with high sensitivity but low specificity. It includes a patient navigation system for education and reminders. The cost is covered by insurance.

Summary: After training and testing, endoscopists showed higher sensitivity but lower specificity compared to the automated software algorithm for ESCN detection. With knowledge of the software algorithm, endoscopists improved their specificity significantly while maintaining high sensitivity and accuracy, especially among novices. The use of computer-assisted diagnosis could facilitate widespread adoption of HRME technology in resource-poor areas.

Summary: This study aimed to explore the additional value of magnifying chromoendoscopy (MCE) in the optical diagnosis of colorectal polyps. The results showed that MCE had higher sensitivity for predicting colorectal cancer with deep invasion. It is recommended to perform additional MCE in lesions with low confidence or diagnosed as deep invasion colorectal cancer by M-NBI.

Summary: This expert review provides best practice advice for the chemoprevention of colorectal neoplasia, recommending the use of low-dose aspirin, metformin, and advising against the use of non-aspirin NSAIDs, calcium, vitamin D for prevention.

Summary: This study characterizes the alteration of the gut virome in azoxymethane-induced colorectal neoplasia in mice and identifies important viruses associated with tumor growth. The research shows that there is a significant shift in viral profile when tumors first appear, and certain viruses from the genera Brunovirus, Hpunavirus are positively associated with tumor growth, while viruses from Lubbockvirus show a negative correlation with tumor growth. These findings provide strong evidence of the potential role of bacteriophage in the development of colorectal neoplasia.

Summary: Improvements in disease management, endoscopic technology, and quality have significantly transformed the conceptualization and management of inflammatory bowel disease-related dysplasia over the past 20 years. A conceptual model and best practice advice have been proposed for the prevention, detection, and management of colorectal dysplasia in individuals with inflammatory bowel disease. This expert review, commissioned by the American Gastroenterological Association, aims to provide timely guidance on a topic of high clinical importance to its membership.

Summary: This study aimed to describe the main diagnostic patterns for ulcerative colitis-associated neoplasia (UCAN), including lateral extension surrounding flat lesions. Through dye chromoendoscopy (DCE) imaging analysis, it was found that lesions with small round or mesh structures were more likely to have high-grade dysplasia or carcinoma. Therefore, when these characteristic mucosal patterns are found in DCE, the possibility of UCAN should be considered.

Summary: The use of high-definition white-light imaging and virtual chromoendoscopy may be sufficient for predicting submucosal invasive cancer in large nonpedunculated colorectal polyps. Additionally, the absence of a demarcated area strongly predicts the absence of submucosal invasive cancer, regardless of the use of dye-based chromoendoscopy.

Summary: The study demonstrated that blue light imaging technology can be taught to endoscopy trainees, and significantly improves the diagnostic accuracy of colorectal polyps after training. With increasing years of training, endoscopy trainees showed significant improvement in the accuracy of polyp characterization.

Summary: This study evaluated the usefulness of acetic acid spray with narrow-band imaging (A-NBI) in visualizing the margin of sessile serrated lesions (SSLs). The study found that A-NBI performed better in terms of visibility score and color differences compared to white-light imaging (WLI), narrow-band imaging (NBI), and indigo-carmine (IC). Conclusion: A-NBI may be a useful modality for identifying the margin of SSLs.

Summary: This study compared the efficacy of narrow-band imaging (NBI) and Lugol chromoendoscopy in screening for esophageal neoplasia among patients with a history of treatment for head and neck squamous cell cancer (HNSCC). The results showed that NBI outperformed Lugol chromoendoscopy in terms of biopsy rate, examination time, and patient tolerance.
