Menetrier's disease is a rare disease of the stomach generally described as hypertrophic gastropathy associated with hypoproteinemia. Gastric resection is still the most definitive treatment for the disease, but the appropriate extent of resection has not been determined. One of the major factors that would determine the extent of gastric resection in Menetrier's disease is its malignant potential. We present two recent cases of Menetrier's disease treated in our institution and review cases of the disease reported in Korea where the incidence of gastric cancer is one of the highest in the world.

OBJECTIVETo study the rule of development of early cancer of gastric cardia in vivo in public screening.

METHODSA prospective cohort study on gastric cardiac cancer was held in the high incidence area of cancer of esophagus and stomach in China. 106 subjects had been examined regularly by endoscopy to observe the change of mucosa in high incidence area of gastric cardiac carcinoma developing at the root of gastric cardiac ridge by taking serial biopsy specimens. All specimens were diagnosed through the normal pathological processes to study the prognosis of pre-cancerous lesion of gastric cardia.

RESULTSThe result of 106 subjects who had been observed for four years were: 1. Of 8 normal persons, 3 stayed normal, 4 turned to chronic gastritis, 1 developed early gastric cardiac cancer. 2. Of 61 persons chronic gastritis, 11 was observed to have glandular atrophy, 4 with mild atypical hyperplasia, and 2 with highly atypical hyperplasia. 3. Of 9 subjects showing atrophic chronic gastritis, 5 revealed no change, and 4 became chronic gastritis. 4. Of 22 subjects who revealed mild atypical hyperplasia, 17 resolved, 4 showed no change, and 1 advanced to highly atypical hyperplasia. 5. One person with highly atypical hyperplasia reverted to mild atypical hyperplasia. 6. Of 5 subjects with early gastric cardiac cancer without any treatment, 1 became advanced cancer, 1 still stayed in early stage, and 3 turned to atypical hyperplasia.

CONCLUSION1. The development of early cancer of gastric cardia would proceed through the stages of chronic gastritis, glandular atrophy, and atypical hyperplasia. 2. The early cancer and pre-cancerous lesion of gastric cardia is reversible, though possessing malignant possibility.

BACKGROUND/AIMS: Focally enhanced gastritis (FEG) has been suggested as a specific diagnostic marker for patients with Crohn's disease (CD). However, the usefulness of FEG for distinguishing CD from ulcerative colitis (UC) is uncertain and the incidence or prevalence of FEG for inflammatory bowel disease (IBD) patients in Korea has not been defined yet. In this study, we investigated the frequency of FEG and other gastric histological abnormalities in Korean patients with CD and UC. METHODS: We evaluated 37 patients with known CD, 43 patients with UC and 41 non-IBD control group; all underwent upper gastrointestinal endoscopy followed by biopsy from the antrum and the body. The pathology of the gastric biopsy specimens and the presence of Helicobacter pylori (H. pylori) were evaluated. FEG was characterized by a focal perifoveolar or periglandular inflammatory cell infiltrates. RESULTS: H. pylori positive gastritis was found in 10 of 37 (27.0%) of CD patients, in 16 of 43 (37.2%) of UC patients, and in 22 of 41 (53.7%) of non-IBD control group (p=0.054). In H. pylori-negative patients, FEG was found in 8 of 27 patients (29.6%) of CD patients, 6 of 27 (22.2%) patients with UC, and 2 of 9 (10.5%) of non-IBD control group (p=0.324). CONCLUSIONS: In H. pylori-negative patients, there was no statistically significant difference in the occurrence of FEG among CD, UC and control groups in Korea.

OBJECTIVES: The objective of this study was to evaluate the prevalence of atrophic gastritis and intestinal metaplasia according to gender, age and Helicobacter pylori infection in a rural population in Korea. METHODS: Between April 2003 and January 2007, 713 subjects (298 men and 415 women, age range: 18-85) among the 2,161 adults who participated in a populationbased survey received gastrointestinal endoscopy. All the subjects provided informed consent. Multiple biopsy specimens were evaluated for the presence of atrophic gastritis and intestinal metaplasia. The presence of Helicobacter pylori was determined using CLO and histology testing. RESULTS: The age-adjusted prevalence of atrophic gastritis was 42.7% for men and 38.1% for women and the prevalence of intestinal metaplasia was 42.5% for men and 32.7% for women. The prevalence of atrophic gastritis and intestinal metaplasia increased significantly with age for both men and women (p for trend<0.001). The ageadjusted prevalence of Helicobacter pylori was similar for men (59.0%) and women (56.7%). The subjects with Helicobacter pylori infection showed a significantly higher prevalence of intestinal metaplasia (44.3%) compared with that (26.8%) of the noninfected subjects (p<0.001). However, the prevalence of atrophic gastritis was not statistically different between the Helicobacter pyloriinfected subjects and the noninfected individuals. CONCLUSIONS: Our findings suggest that the prevalence of atrophic gastritis and intestinal metaplasia is higher for a Korean rural population than that for a Western population; this may be related to the high incidence of gastric cancer in Koreans. Especially, the prevalence of intestinal metaplasia was high for the subjects with Helicobacter pylori infection. The multistep process of gastric carcinogenesis and the various factors contributing to each step of this process need to be determined by conducting future follow-up studies.

The concordance between endoscopic and histological gastritis was determined in 52 patients referred for upper gastrointestinal endoscopy. The study was conducted in Northeastern Peninsular Malaysia, an area with a low background prevalence of H. pylori infection. Endoscopic and histological gastritis were assessed in accordance with the Sydney System. The results showed poor concordance between endoscopic and histological gastritis even after reclassifying mild endoscopic gastritis as normal. The low prevalence of H. pylori was validated in this study.

BACKGROUND: Reflux esophagitis is inversely associated with the presence of atrophic gastritis, and endoscopic grading of atrophic gastritis correlates with histological evaluation. The aim of this study was to investigate the association of the endoscopic grade of atrophic gastritis with gastroesophageal and gastropharyngeal reflux. METHDOS: A total of 627 patients, who underwent endoscopy and ambulatory 24-hour dual-probe pH monitoring, were included in this study. The grade of atrophic gastritis was endoscopically classified into 2 types with the atrophic pattern system: the closed-type (C-type) and the open-type (O-type). We compared the findings from endoscopy and ambulatory pH monitoring for these 2 types. RESULTS: The O-type was significantly associated with a lower prevalence of reflux esophagitis (p=0.001). All variables showing gastroesophageal reflux in the distal probe were significantly lower in the O-type than in the C-type (p<0.05). Similarly for the proximal probe, all variables, except the supine time of pH<4, were significantly lower in the O-type than in the C-type (p<0.05). The frequency of gastroesophageal reflux disease and gastropharyngeal reflux disease was in significantly lower in the O-type than in the C-type (p<0.001, p=0.012, respectively). CONCLUSIONS: Endoscopic grading of atrophic gastritis is easy and is inversely associated with gastroesophageal and gastropharyngeal reflux.

INTRODUCTIONWe aimed to examine the turnover of chronic atrophic gastritis (CAG) pathologically and endoscopically and explore its potential causes.

METHODSA retrospective analysis was conducted of prospective data collected from 1,592 patients who underwent gastroscopy three times or more during the period 1985-2009 at Renji Hospital, Shanghai, China. Pathological and endoscopic findings were analysed. Data collected included gender, age, length of follow-up period, family history, past medical history, history of Helicobacter (H.) pylori infection, drug history for the use of proton pump inhibitors (PPIs), antacids and non-steroidal anti-inflammatory drugs [NSAIDs], and lifestyle history, including the patients' eating habits.

RESULTS23 (1.44%) patients presented with gastric cancers resulting from CAG and 349 (21.92%) patients had dysplasia. Pathological and endoscopic findings suggested that the proportion of patients with worsening gastric mucosa during the atrophic and intestinal metaplasia (IM) phases was over 35% with increasing age. Gastric mucosa was found to be pathologically aggravated by carbonated drinks and fast food, and pathologically degenerated by H. pylori infection. Smoking deteriorated the gastric mucosa. Side dishes of vegetables may benefit the gastric mucosa even in the atrophic and IM phases.

CONCLUSIONOur findings support the consensus that CAG is a progressive disease. Potential factors that were found to affect the state of the gastric mucosa in our patient group were gender, H. pylori infection, use of PPIs or NSAIDs, and intake of vegetable side dishes, spicy food, carbonated drinks and fast food.

Helicobacter pylori has been strongly associated with gastritis, gastric and duodenal ulcers, and it is a risk factor for gastric cancer. Two major virulence factors of H. pylori have been described: the cytotoxin-associated gene product (cagA) and the vacuolating toxin (vacA). Since considerable geographic diversity in the prevalence of H. pylori virulence factors has been reported, the aim of this work was to determine if there is a significant correlation between different H. pylori virulence genes (cagA and vacA) in 68 patients, from Saudi Arabia, and gastric clinical outcomes. H. pylor was recognized in cultures of gastric biopsies. vacA and cagA genes were detected by polymerase chain reaction (PCR). The cagA gene was obtained with 42 isolates (61.8%). The vacA s- and m- region genotypes were determined in all strains studied. Three genotypes were found: s1/m1 (28%), s1/m2 (40%) and s2/m2 (26%). The s2/m1 genotype was not found in this study. The relation of the presence of cagA and the development of cases to gastritis and ulcer was statistically significant (P < 0.05). The study showed a significant correlation between the vacA s1/m2 genotype and gastritis cases, and a significant correlation between vacA s1/m1 genotype and peptic ulcer cases. The results of this study might be used for the identification of high-risk patients who are infected by vacA s1/m1 genotype of H. pylori strains. In conclusion, H. pylori strains of vacA type s1 and the combination of s1/m1 were associated with peptic ulceration and the presence of cagA gene.
