Role of digital chromoendoscopy and confocal laser endomicroscopy for gastric intestinal metaplasia and cancer surveillance

Table 1 Sensitivities of different endoscopic technologies for gastric intestinal metaplasia detection

Endoscopy in GIM	Ref.	Sensitivity (%)
White light endoscopy	Sauerbruch et al[19]	< 50
Digital chromoendoscopy (NBI)	Capelle et al[5]	71
Methylene blue magnified chromoendoscopy	Dinis-Ribeiro et al[22]	76
Digital magnified chromoendoscopy (Non-sequential-NBI)	Rerknimitr et al[7]	91
Digital magnified chromoendoscopy (sequential-NBI)	Uedo et al[4]	89
Endoscopic-based confocal laser endomicroscopy	Guo et al[40]	98

GIM: Gastric intestinal metaplasia; NBI: Narrow-band Imaging.
