Advanced technology for assessment of endoscopic and histological remission in ulcerative colitis: a systematic review and meta-analysis

Aims Advanced endoscopic technologies led to significant progress in the definition of endoscopic remission of ulcerative colitis (UC), and correlate better with histological changes, compared to standard endoscopy. However, whilst studies have assessed the diagnostic accuracy of endoscope technologies individually, there is current limited data comparing between technologies. As such, the aim of this systematic review was to compare the correlations between endoscopy and histology disease activity scores across endoscope technologies
