Gastritis caused by Helicobacter Pylori Infection

Marscall and WarrenBarry Marschall and Robin Warren (to the right) are the two doctors and scientists, who discovered Helicobacter Pylori in 1983. This picture was taken in Lissabon in 1997.
Antral Gastritis caused by Helicobacter pyloriWith a modern videoendoscope it is possible to see very tiny changes in the gastric mucosa. This mucosal pattern is typical of a gastritis caused by Helicobacter pylori
Helicobacter GastritisThe mucosal changes are not always easy to see, and one should go very close to the mucosa with the endoscope.
 
Helicobacter GastritisThis small but clearly visible granulation of the mucosa in the gastric corpus, here seen with the gastroscope in an inverted position, is due to Helicobacter infection.
Helicobacter Ureas TestThe fastest to prove a Helicobacter infection is by the Helicobacter Urease Test (HUT-test). The urease enzyme produced by the Helicobacter cause a colour change in a small reagence tube, usually within minutes. A-C- = Biopsy from antrum is negative, Corpus is negative. A+C+ = Antrum is positive, Corpus is positive
HUT-testA+C- = Antrum is positive, Corpus is negative. A+C+ = Antrum is positive, Corpus is positive.
Suction mark in the mucosaDuring an endoscopy gastric fluid is suctioned away to improve visibility. A healthy mucosa can withstand suction without lesions. A mucosa injured by Helicobacter infection cannot, and after suction one can see a little lesion like this in the mucosa.
Suction mark in the mucosaIn this picture two typical mucosal suction marks are seen.

The Best Image Library in the World!That is what we would like Gastrolab Image Library and Endoscopic Archives to be.Perhaps We can achieve this together? Many of You have ecxellent endoscopic images just waiting for publication. When published they can be an invaluable resource for young endoscopists and for gastroenterologic education. Images published here can freely be used for noncommercial purposes. So, please email Your images here Together we can make the best and most complete Image Library in the World! |
