Helicobacter pylori in gastric corpus of patients 20 years after partial gastric resection

Table 1 Histology in the corpus and cardia of partial gastrectomy patients

	corpus			cardia
	HP + n = 25	HP –n = 32	P	HP + n = 25	HP –n = 32	P
Grade of gastritis
Grade 0 or 1, n (%)	24 (96)	32 (100)	-	24 (96)	32 (100)	-
Grade 2 or 3, n (%)	1 (4)	0	0.439	1 (4)	0	0.439
Activity of gastritis
Grade 0 or 1, n (%)	16 (64)	32 (100)	-	16 (64)	32 (100)	-
Grade 2 or 3, n (%)	9 (36)	0	< 0.0005	9 (36)	0	0.007
Regenerative epithelium
Grade 0 or 1, n (%)	25 (100)	32 (100)	-	24 (96)	32 (100)	-
Grade 2 or 3, n (%)	0	0	-	1 (4)	0	0.439
Intestinal metaplasia
Present, n (%)	5 (20)	7 (22)	1.00	4 (16)	4 (12.5)	0.720
Atrophy
Present, n (%)	11 (44)	6 (19)	0.047	0	3 (9.5)	0.248

No partial gastrectomy patient had a grade 2 or 3 regenerative type of epithelium in the corpus. Based upon this result a statistical analysis with regard to regenerative type of epithelium in the corpus was not appropriate.
