- Abstract
- Helicobacter pylori is known to show an uneven distribution on human gastric mucosa. Endoscopic procedure by phenol red dye spraying
is simple and direct visual method to clarify the presence and the distribution of Helicobacter pylori. After the initiation of Helicobacter
pylori eradication, the prevalence of Helicobacter pylori infection may has been changed. Therefore, we compared the patterns of
Helicobacter pylori distribution by endoscopic phenol red dye spraying method for 10 years. From January 1996 to December 1996, 100
patients and from April 2004 to July 2006, 112 patients with functional dyspepsia were recruited into the study. Functional dyspepsia was
defined according to Rome II criteria. The distributed patterns of Helicobacter pylori were classified into 4 patterns; unstained, patchy,
regional and diffuse pattern. The results were following table. In conclusion, The distributed patterns of Helicobacter pylori by phenol red
dye spraying had been changed for 10 years; Unstained and patchy patterns increased and regional patterns decreased in the gastric
antrum, and patchy pattern increased and regional pattern decreased in the gastric body compared to 10 years ago.
