Benefits of the Seattle biopsy protocol in the diagnosis of Barrett’s esophagus in a Chinese population

Table 3 Results of the two different biopsy protocols n (%)

	NBI-targeted biopsy	Seattle protocol-guided biopsy	P-value
IM (n = 65)	45 (69.2)	51 (78.5)	0.2312
Dysplastic tissue
Group A (n = 20)	0 (0.0)	2 (10.0)2	0.4871
Group B (n = 31)	1 (3.2)2	3 (9.6)1	0.6121
Group C (n = 14)	0 (0.0)	0 (0.0)	1.0001

¹P-values were analyzed with Fisher’s exact test;

²P-values were analyzed with Pearson’s χ² test. All dysplastic tissues were low-grade dysplasia except one adenocarcinoma in Group B detected via Seattle protocol guided biopsy. IM: Intestinal metaplasia; NBI: Narrow-band imaging.
