Endoscopic and blood test findings for gastritis based on actual cases

If the status of Helicobacter pylori infection was classified into current infection, past infection, and non-infection and reported to the examinee after the gastroscopy, all citizens over the age of 40 would not have to undergo gastroscopy every two years.
Patients with autoimmune gastritis or Helicobacter pylori infection, which have a high incidence of gastric cancer, should undergo regular gastroscopy after eradication treatment, but those without infection have a low incidence of gastric cancer and thus do not need gastroscopy.

This book was written under the assumption that readers are familiar with the contents of the book 『Endoscopic Findings of Gastritis』 written in 2019.
I think this is essential knowledge in these times when gastroscopy is performed so frequently.
By organizing the endoscopic findings together with the blood test results, we also included information on how to interpret the values ​​after gastrectomy or eradication treatment, or when taking acid suppressants, which are relative contraindications to the pepsinogen test.
As you come across cases, you will realize that “an accurate diagnosis of gastritis is completed through a blood test.”
