Abstract
The role of Helicobacter pylori (HP) was studied in 53 cases with gastritis after distal partial gastrectomy. The percentage of HP positive patient of these 53 cases was lower than in other disease (atrophic gastritis, hemorrhagic gastritis and gastric ulcer) . There was no significant difference in endoscopic findings between positive and nagative cases for HP culture. Histologically, gastritis was more severe in positive cases for HP culture than in negative cases. The percentage of bile reflux was higher in negative cases for HP culture. Influences upon HP culture of bile juice, ursodeoxycholic acid and chenodeoxycholic acid were examined, and the results showed that these 3 materials seemed to inhibit HP growth in medium. These results suggest that HP has little influence upon gastritis after gastrectomy.
