Helicobacter pylori infection following partial gastrectomy for gastric cancer

Table 1 Differences in the characteristics and manifestations of different gastric resections recently presented

Manifestations	Distal gastrectomy	Proximal gastrectomy
Bile reflux	↑	↓
Polymorphonuclear infiltration (i.e., rate of inflammation)	↑ (60.5%)	↓ (12.9%)
H. pylori infection rate	↑	↓
Chronic and active inflammation	↑	↓
Intestinal metaplasia	↓	↑

It is suggested that the presence of a gastric stump after proximal gastrectomy promotes the progression of intestinal metaplasia and hampers the colonization of Helicobacter pylori (H. pylori). However, this notion is contrary to results from previous studies showing a relatively low H. pylori prevalence in the gastric stump.
