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...

Endoscopic forceps biopsy is essential before planning an endoscopic resection of upper gastrointestinal epithelial tumors. However, forceps biopsy is limited by its superficiality and frequency of sampling errors. Histologic discrepancies between endoscopic forceps biopsies and resected specimens are frequent. Factors associated with such histologic discrepancies are tumor size, macroscopic ty...

An audit of upper gastrointestinal endoscopy in HIV infected patients with gastrointestinal symptoms assessed the frequency of disease detected by endoscopy and routine laboratory analysis of surveillance biopsy specimens. Sixty nine consecutive endoscopies were performed in 59 HIV infected patients. Endoscopic biopsy specimens were taken from the lower oesophagus, gastric antrum, and third par...

background : many  helicobacter pylori strains express adhesin proteins that bind to specific  host-cell  macromolecule  receptors,  like sialic acid binding adhesion ( saba ).    saba-expressing  strains have been associated with gastric cancer  and  negatively  associated   with  duodenal   ulcers. the  aim  of  this study  was  to  determine   the  status  of   saba   gene  of   h.  pylori  ...

Campylobacter pyloridis is strongly associated with the presence of histological gastritis,1 2 but its role in the aetiology of peptic ulcer disease and non-ulcer dyspepsia has yet to be determined. Its detection in antral mucosal biopsy specimens usually entails histo-logical or microbiological methods that may require several days for a result. In a previous study3 we found that direct examin...

Background and Objective: Helicobacter Pylori (H. pylori) is one of the reasons for the gastric inflammation and peptic ulcers. It is a predisposing factor of gastric adenocarcinoma. Cytotoxin A encoded by the cagA gene is one of the major virulence factors in bacterial pathogenicity, which is of special importance due to genetic diversity in different geographical areas. The purpose of this st...

Gastric adenocarcinoma after gastric bypass for morbid obesity is rare but has been described. The diet restriction, weight loss, and difficult assessment of the bypassed stomach, after this procedure, hinder and delay its diagnosis. We present a 52-year-old man who underwent Roux-en-Y gastric bypass 2 years ago and whose previous upper digestive endoscopy was considered normal. He presented wi...

The sequence of events in the gastric mucosa that precede the manifestation of gastric cancer has been shown to begin decades earlier. Typically, it begins with chronic non-atrophic gastritis that progresses to chronic atrophic gastritis, which may eventually lead to intestinal metaplasia, dysplasia, and finally adenocarcinoma (Kuipers, 1999). Helicobacter pylori infection is accepted as the pr...
