Usefulness of Chromoendoscopy for the Early Detection of Colorectal Cancer Associated With Inflammatory Bowel Disease

Usefulness of Chromoendoscopy for the Early Detection of Colorectal Cancer Associated With Inflammatory Bowel Disease

To assess the feasibility and effectiveness of a program in L-IBD patients using CE targeted biopsies

We aim to know the prevalence and incidence of dysplasia and colitis-associated colorectal cancer in patients with longstanding colonic inflammatory bowel disease (N-IBD), in Spain and the usefulness of advanced endoscopy (chromoendoscopy) for the diagnosis and endoscopic differential diagnosis of N-IBD.

Inclusion Criteria:

• Diagnosis of UC or colitis EC corroborated by clinical and histology
• involvement of at least one third of the colon in patients with CD
• involvement proximal to the rectum in patients with UC
• Duration of disease > 10 years
• No clinical activity:
• May Score <6
• CDEIS <3.5

Exclusion Criteria:

• Personal history of CRC
• colectomy
• coagulopathy
• refusal to participate in the study
• known allergy to indigo carmine
• colonoscopy in the last 6 months
