104th Meeting of Japan Society of Gastroenterology in 2018

Date: 19 April, 2018

Place: Keio Plaza Hotel, Tokyo

Panel discussion 3: Long-term results after eradication of Helicobacter pylori

Abstracts: Journal of Japanese Socirty of Gastroenterology 2018; 115: A80-82.

PD3-2
Risk factor of reflux esophagitis after eradication of H. pylori

Yoshida Y, et al. Matsuyama Red Cross Hospital

Number of subjects: 1575

Observation period: 8.5 years

The rate of newly developing reflux esophagitis in the patient after eradication of H. pylori is 10.1%. Risk factors were sex (male), obese, and hiatal hernia.

PD3-3
Changes of gastritis after eradicating Helicobacter pylori: relationship with age

Raku H, et al. Okayama University

Number of subjects: 300

Observation period: 2-3 years

In the group of young people with low grade atrophic gastritis and intestinal metaplasia, grade of gastritis was improved.

PD3-4
Risk assessment of gastric cancer after eradicating H. pylori;

Endoscopic atrophic gastritis or histological intestinal metaplasia: Which is useful?

Niikura R, et al. Tokyo University

Number of subjects: 655

At the average 6.8 after eradication, in 25 patients, new gastric cancer was occured. Histological intestinal metaplasia was related with the risk of developing gastric cancer than endoscopic findings.

PD3-5
Irregular gastric mucosa which occurred after eradicating H.pylori, makes it difficult to detect new gastric cancer

Yamazaki T, et al. Tokyo Jikei Medical School

Due to eradicating H. pylori, endoscopic findings diversify, making diagnosis of gastric cancer might be difficult.

PD3-6
Newly Gastric cancer after eradicating H. pylori often occurs in the intermediate zone

Yagi K, et al. Niigata University

PD3-7
Characteristics of new gastric cancer after eradication of pylori

Satoh T, et al. Yokohama City University

Number of cancers: 201 of gastric cancer after eradication of pylori

Observation period: 33 month

The morphological features of gastric cancer after eradicationg  H.pylori were small and depressive. Gastric cancer after eradication occurred statistically significantly more than non-eradicating group.

PD3-8
Characteristics of gastric cancer after eradicating H. pylori

Nakano K, et al. Cancer Institute Ariake Hospital of JFCR

Gastric cancer after eradicating H. pylori is increasing. 152 patients with early gastric cancer who were eradicated H.pylori were treated within 2.5 years in their institution.They were found on average 4.5 years after eradicating H. pylori. The morphological features of gastric cancer after eradicationg H.Pylori were small, red, and depressive. The size of gastric cancers which found after 10 years or more were larger than within 10 years.

Comment by Uno

Gastric cancer after eradicating H pylori is increasing in Japan (PD3-8). Such new cancer is very difficult to find (PD3-5). Even in endoscopists of high-level research facilities, this problem is serious (PD3-5,PD3-6, PD3-7, PD3-8). This problem is an issue for the entire Japanese citizen. Due to a lack of information, patients tend to believe that gastric cancer cannot occur after H. pylori eradication without a follow-up. What should we do to save the patient? By accepting the truth and pursuing the cause, we can open a new door.
