Clinical relevance of endoscopic assessment of inflammation in ulcerative colitis: Can endoscopic evaluation predict outcomes?

Figure 1 Assessment of inflamed colon with white light endoscopy, narrow band imaging and chromoendoscopy. A: White light assessment with standard definition endosocpe reveals areas with superficial ulceration interspersed with areas of patchy obliteration of mucosal vascular pattern; B: High resolution endoscope allows more detailed assessment including crypt openings and disrupted vascular architecture; C: NBI assessment of moderately active UC shows obscured vascular pattern; white mucosal spots which represent mucous exudates giving the characteristic appearance of “Coral reaf” like mucosa; D: Chromoendoscopy shows the mucosal damage with disruption of pit pattern and complete destruction of vascular pattern. Ulcer margins are seen more prominent with contrast enhancement.
