abstractintroduction: hyperplastic polyps of the esophago-gastric junction are seen during endoscopic evaluation of upper gastrointestinal tract. they are usually asymptomatic and discovered accidentally during endoscopic evaluation for other problems. these protrusions are mucosal regenerative response to surrounding mucosal injury. case: here we present a 9-year-old boy presenting with abdomi...

Experience of 70 gastroscopies with direct-vision biopsy is favourable and indicates that this instrument will be of great assistance in certain difficult diagnostic problems of gastric pathology.

We developed and evaluated a simple, novel multiplex PCR assay for rapid detection of Helicobacter pylori infection and for the determination of vacA and cagA genotypes directly from gastric biopsy specimens. This assay did not require culturing of strains or extraction of DNA from biopsy samples. This multiplex PCR assay would be of particularly great value for laboratories in developing count...

Helicobacter Pylori (H. pylori) as a gram-negative bacterium is the most common infection of the gastrointestinal tract, and worldwide it affects the children over three years of age. H. pylori could cause gastrointestinal and extra-intestinal manifestations. Antibiotic resistance can happen primarily and occurs during treatment. We aimed to evaluate the resistance gene of H. pylori obtained fr...

Gastric metastasis from ovarian cancer is exceptionally rare and generally occurs in advanced stages. A 71-year-old woman presented with a solitary gastric submucosal mass 8 years after the diagnosis of a stage IA ovarian serous adenocarcinoma. Endoscopy showed a tumor covered with normal gastric mucosa. Initially, a gastrointestinal stromal tumor was suspected, but biopsy revealed a histology ...

BACKGROUND AND STUDY AIMS The HER2 status of small endoscopic biopsies is important for predicting the eligibility of patients with metastatic HER2-positive gastric cancer or gastro-esophageal junction (GEJ) cancer for anti-HER2 therapy approved by the U.S. Food and Drug Administration. The aim of this study was to identify the minimum biopsy set required to evaluate the HER2 status with confid...

gastric adenocarcinoma is the second leading cause of death due to cancer in the world and in advanced stages the prognosis is poor with current therapies. over-expression of her-2/neu has been seen in several cancers such as gastric cancer and its expression is associated with poor prognosis. the aim of this study is to evaluate the over-expression of her-2/neu in gastric biopsy samples of pat...

The gastric mucosal immune response is thought to be comprised predominantly of the Th1 type; however, there are limited data regarding the role of IL-18 in Helicobacter pylori-induced inflammation. We investigated IL-18 levels in gastric mucosal biopsy specimens as well as in isolated gastric epithelial cells and lamina propria mononuclear cells. We also investigated IL-18 levels in gastric ep...

during a regular health check−up in a 59− year−old man. Following barium meal study the SMT was shown to be growing. He visited our hospital for further exami− nation. The upper gastrointestinal endoscopy re− vealed an SMT in the posterior wall of the upper third area of the stomach, with bridging fold and positive cushion sign (l" Figure 1). A focal discoloration of mu− cosa at the top of the ...
