The efficacy of gastric X-ray findings in assessing
Helicobacter pylori (H. pylori) eradication was investigated by studying X-ray findings before and after successful
H. pylori eradication. Prior to and one year following successful
H. pylori eradication, double contrast gastrography in the supine position were examined for mucosal fold width; gastric area at the fundic gland mucosa; the fundic-pyloric gland border ; and contrast medium adhesion to the gastric wall.
Subjects were eight patients in whom successful
H. pylori eradication was confirmed. There were four men with an average age of 44.5 years and four women with an average age of 41.7 years. Prior to eradication, one patient had gastric ulcer, five patients had duodenal ulcer or ulcer scar, one patient had chronic gastritis, and one patient had gastric erosion.
Of the eight patients, mucosal fold width was measured before and after eradication in seven patients, and the width decreased in all seven patients. Gastric area was assessed before and after eradication in six patients, and a decrease was seen in four patients : from F
1 type (large) to F
2 or F
3 type (small) . However, there was no change in the fundic-pyloric gland border in any of the patients before and after eradication. Contrast medium adhesion did not exacerbate after eradication in any of the patients. Of the eight patients, adhesion was favorable in four patients before eradication and in seven patients after eradication.
These findings suggest that it is possible to assess
H. pylori eradication by determining mucosal fold width, gastric area of the fundic gland mucosa, and contrast medium adhesion on double contrast gastrography.
