The gastritis associated with chronic gastric ulcer has been studied by means of biopsy specimens taken under vision through a fibreoptic gastroscope from four standard sites in the stomach. Observations have been made in patients with untreated gastric ulcer and also in patients after medical or surgical treatment of the ulcer. The gastritis is usually widespread in chronic peptic ulcer of the...

The frequency of gastric Crohn's disease has been considered low. This study was undertaken to determine the prevalence of chronic gastritis and Helicobacter pylori infection in patients with Crohn's disease. Oesophagogastroduodenoscopy was performed on 62 consecutive patients suffering from ileocolonic Crohn's disease. Biopsy specimens from the antrum and corpus were processed for both histolo...

A total of 98 patients, who had undergone gastric surgery (23), or who had peptic ulcers (56), or who had normal endoscopic findings (19) underwent gastric biopsy, together with measurement of pH and total bile acid concentration, in their fasting gastric juice. The biopsy specimens were stained by the Warthin-Starry method for Campylobacter like organisms and were also graded "blind," as descr...

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...

BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a common surgical therapeutic option for obese patients, with debate about the value of routine histopathologic examination of LSG specimens. We assessed the following: prevalence of different histopathologic changes in LSG specimens, risk factors associated with premalignant and with frequent histopathologic changes, and whether routine histo...

PURPOSE Histologic assessment of high-risk gastritis for the development of gastric cancer is not well defined. The identification of tissue markers together with the integration of histologic features will be required for this assessment. EXPERIMENTAL DESIGN Matched tumor/nontumor adjacent mucosa (NTAM) of 91 early gastric cancer and 148 chronic gastritis cases were evaluated for histologic ...

BACKGROUND Infection with Helicobacter pylori is considered a potential risk of developing gastric cancer in association with contributing host genetic factor. IL-1β and IL-1RN polymorphisms appear to maintain and promote Helicobacter pylori infection and to stimulate neoplastic growth of the gastric mucosa. OBJECTIVE AND METHODS In order to elucidate the effect of these polymorphisms in comb...

OBJECTIVE To investigate the distribution of H.pylori antigens in the gastric mucosa in patients with H.pylori infection, and the relationship between the distribution and gastric cancer. METHODS Of 112 patients confirmed by pathological study to have chronic superficial gastritis, precancerous changes (chronic atrophic gastritis, intestinal metaplasia or atypical hyperplasia) and gastric can...

BACKGROUND The aim of this study was to determine the value of 18F-FDG uptake on screening PET/CT images for the prediction of Helicobacter pylori (H. pylori) infection and chronic atrophic gastritis. METHODS Among subjects who underwent 18F-FDG PET/CT for cancer screening from April 2005 to November 2015, PET/CT images were analyzed in 88 subjects who had gastrointestinal fiberscopy within 6...
