Crystal Violet Staining for Colitis-associated Neoplasia-guided Delineation of Ulcerative Colitis-associated Neoplasia for Endoscopic Submucosal Dissection: A Four-case Report.

Better delineation of dysplastic or neoplastic areas in ulcerative colitis can increase chances of complete endoscopic removal and help detect residual disease that white-light imaging misses.

The Efficacy of Lactobacillous Probiotic and Trace Elements in the Management of Ulcerative Colitis Patients the Patient Will be Recruited From Outpatient Clinic of IBD and Gastroenterology of the National Hepatology and Tropical Medicine Research Institute (NHTMRI), Cairo, Egypt.

The trial tests two low-cost adjuncts — a Lactobacillus probiotic and a multi–trace-element supplement — added to biologic-based standard care to see if they help maintain remission in ulcerative colitis. If effective,...

Prevalence and risk factors of pre-neoplastic polyps in patients with ulcerative colits: a cross-sectional retrospective study.
Einstein (Sao Paulo, Brazil)

Prevalence and risk factors of pre-neoplastic polyps in patients with ulcerative colits: a cross-sectional retrospective study.

Preneoplastic (adenomatous and serrated) polyps can be precursors to colorectal cancer, so knowing how common they are and what raises risk may affect surveillance planning for people with ulcerative colitis.

FreqMamba-Net: a frequency-enhanced state space model for fine-grained mucosal lesion segmentation in colonoscopy.

Better automated segmentation of inflammatory lesions could make colonoscopy assessments more objective and consistent, which matters for monitoring IBD activity and for clinical trials that rely on endoscopic endpoints.

Endocytoscopic Classification Is Associated with Mucosal miR-192-5p Downregulation and CXCL2 Expression in Ulcerative Colitis: An Exploratory Study

If confirmed, an endocytoscopic appearance that corresponds to a specific miRNA and chemokine pattern could help clinicians assess mucosal inflammation during colonoscopy and prioritize biopsies or treatment decisions...
