THE IMPORTANCE OF COLONOSCOPY IN INFLAMMATORY BOWEL DISEASES

Area of Science:

• Gastroenterology
• Internal Medicine
• Diagnostic Imaging

Background:

• Inflammatory bowel disease (IBD) management relies heavily on endoscopic evaluation, including macroscopic and histological assessments of ileocolic biopsies.
• Differentiating between Crohn's disease (CD) and ulcerative colitis (UC) solely on endoscopic appearance can be challenging, though certain features suggest one diagnosis over the other.
• Both CD and UC patients face an increased risk of colorectal carcinoma, necessitating surveillance colonoscopies for early detection of neoplastic lesions.

Purpose of the Study:

• To review and update the significance of endoscopy in the evaluation, diagnosis, and prognosis of inflammatory bowel disease.
• To highlight the role of colonoscopy in cancer surveillance for IBD patients.

Main Methods:

• A literature search was conducted using the TRIP database, focusing on clinical questions (PICO).
• Keywords included: "inflammatory bowel disease", "endoscopy/colonoscopy", "Crohn's disease", "ulcerative colitis", and "diagnosis/treatment".

Main Results:

• Endoscopic investigation accurately differentiates between ulcerative colitis and Crohn's disease in patients with chronic colitis.
• Endoscopy is indicated during severe ulcerative colitis crises for its prognostic value and for screening dysplastic lesions in inflammatory bowel disease.
• Ileocolonoscopy achieves up to 90% diagnostic accuracy for Crohn's disease or ulcerative colitis.

Conclusions:

• Endoscopic assessment of mucosal healing is a key indicator for evaluating disease remission in inflammatory bowel disease.
• Colonoscopy is vital for long-term cancer surveillance in IBD patients.
• Confocal Laser Endomicroscopy shows promise for early dysplasia detection in the future.
