AI-driven Narrow-band Imaging Score for Disease Assessment and Outcome Prediction in Ulcerative Colitis

Colonoscopy will be performed using HD-WLE; TXI; RDI and NBI.

During colonoscopy, at least 2 biopsies from each segment will be taken as standard of care to assess inflammation in UC

Blood samples will be taken for standard of care by appropriately trained members of the clinical research team. The results of the standard of care blood will be used in the research.

The stool sample will be sent to the laboratory for Faecal Calprotectin (FCP) as a marker of disease activity.

Patients will be followed-up at 6 and 12 months after index endoscopy. Patients will be evaluated in clinic or by telephone call and the disease will be reassessed. Partial Mayo Score (PMS) and occurrence of clinical outcomes will be evaluated.
