<b><i>Introduction:</i></b> The aim of this study was to study the relationship between the formation of gastric fundic gland polyp and gastric hyperplastic polyp (HP) and the changes of gastric juice microenvironment. <b><i>Methods:</i></b> The proton-pump inhibitor (PPI) applications to patients were recorded. Gastric juices and biopsy polyps were collected for pathological examination, <i>H. pylori</i> tests, biomarkers, and <i>MUC1</i>, <i>MUC2</i>, <i>MUC5AC expression</i> measurement. <b><i>Results:</i></b> Among 34,892 patients, the detection rate of gastric fundic gland polyps was significantly higher than that of gastric HPs (<i>p</i> &#x3c; 0.01). The incidence rate of gastric fundic gland polyp and gastric HP in PPI users (<i>n</i> = 3,886) was higher than that of non-PPI users (<i>p</i> &#x3c; 0.01). The occurrence of polyp was positively related to the duration of PPI application and the <i>H. pylori</i>-positive rate. The bile reflux rate between fundic gland polys group (17.61%) and HPs (28.67%) was significantly different (<i>p</i> &#x3c; 0.01). The levels of gastric juice Gastrin-17, epidermal growth factor (EGF) and MUC<sub>2</sub> from patients with gastric fundic gland polyps and gastric HPs were higher than those in the control group (<i>p</i> &#x3c; 0.01). However, patients with gastric fundic gland polyps and HPs had significantly lower gastric juice PGE<sub>2</sub> and MUC5AC (<i>p</i> &#x3c; 0.01). <b><i>Conclusion:</i></b> PPI application, <i>H. pylori</i> infection, and bile reflux are the potential risk factors for formation of fundic gland polyps and HPs. The potential mechanism of polyps’ formation can be related to the levels of Gastrin-17, EGF, MUC<sub>2</sub>, PGE<sub>2</sub>, and MUC5AC in gastric juice.

ABSTRACT Background: Studies with latest technologies such as endoscopy with magnification and chromoendoscopy showed that various endoscopic aspects are clearly related to infection by Helicobacter pylori (HP). The description of different patterns of erythema in gastric body under magnification of images revived interest in identifying these patterns by standard endoscopy. Aim: To validate the morphologic features of gastric mucosa related to H. pylori infection gastritis allowing predictability of their diagnosis as well as proper targeting biopsies. Methods: Prospective study of 339 consecutive patients with the standard videoendoscope image analysis were obtained, recorded and stored in a program database. These images were studied with respect to the presence or absence of H. pylori, diagnosed by rapid urease test and/or by histological analysis. Were studied: a) normal mucosa appearance; b) mucosal nodularity; c) diffuse nonspecific erythema or redness (with or without edema of folds and exudate) of antrum and body; d) mosaic pattern with focal area of hyperemia; e) erythema in streaks or bands (red streak); f) elevated (raised) erosion; g) flat erosions; h) fundic gland polyps. The main exclusion criteria were the use of drugs, HP pre-treatment and other entities that could affect results. Results: Applying the exclusion criteria, were included 170 of the 339 patients, of which 52 (30.58%) were positive for HP and 118 negative. On the positive findings, the most associated with infection were: nodularity in the antrum (26.92%); presence of raised erosion (15.38%) and mosaic mucosa in the body (21.15%). On the negative group the normal appearance of the mucosa was 66.94%; erythema in streaks or bands in 9.32%; flat erosions 11.86%; and fundic gland polyps 11.86%. Conclusion: Endoscopic findings are useful in the predictability of the result and in directing biopsies. The most representative form of HP related gastritis was the nodularity of the antral mucosa. The raised erosion and mucosa in mosaic in the body are suggestive but not specific to the infection. The other forms were not conclusive of the presence of HP.

<b><i>Background:</i></b> Gastric adenocarcinoma of foveolar type (GA-FV) is a raspberry-shaped gastric cancer (RSGC) and garners much attention as <i>H. pylori</i> (<i>Hp</i>)-uninfected gastric cancer. However, the classification and clinicopathological and endoscopic features of RSGCs in <i>Hp</i>-uninfected patients are poorly defined. We designed a new histopathological classification of RSGC and compared them via endoscopic and clinicopathological characteristics. <b><i>Summary:</i></b> From 996 patients with early gastric cancers resected by endoscopy in our hospital, we studied 24 RSGC lesions from 21 (2.4%) <i>Hp</i>-uninfected patients. RSGCs were classified into 3 histological types as follows: GA-FV (<i>n</i> = 19), gastric adenocarcinoma of fundic gland type (GA-FG, <i>n</i> = 2), and gastric adenocarcinoma of fundic gland mucosa type (GA-FGM, <i>n</i> = 3). Most of the lesions were found at the greater curvature of the upper or middle third of the stomach. GA-FV lesions were homogeneously reddish and frequently accompanied with a whitish area around the tumor and an irregular microvascular (MV) pattern; these features were confirmed histopathologically by the presence of homogeneous neoplastic foveolar epithelium with foveolar hyperplasia around the tumors. GA-FG lesions might be heterogeneously reddish with a submucosal tumor shape and regular MV pattern; these were confirmed by the presence of covered or mixed nonneoplastic epithelium on deeper regions of tumors. GA-FGM lesions might be homogeneously reddish and occasionally had a submucosal tumor shape and irregular MV pattern; these were confirmed by the presence of homogeneous neoplastic foveolar epithelium on deeper regions of the tumors. <b><i>Key Messages:</i></b> RSGCs in <i>Hp</i>-uninfected patients are classified into 3 histopathological types. For accurate diagnosis of RSGCs, it may be necessary to fully understand endoscopic features of these lesions based on these histological characteristics and to take a precise biopsy.

Introduction: Since inflammatory cells, such as lymphocytes and plasma cells, normally inhabit the stomach, the border between normal and mild inflammation is difficult to visually determine using the updated Sydney system scale of gastritis. Additionally, eosinophils in the gastric mucosa must be counted to diagnose eosinophilic gastritis. We aimed to determine the normal number of inflammatory cells in patients with endoscopically normal mucosa and without H. pylori infections. Methods: We assessed patients aged 20–79 years, who had undergone upper gastrointestinal endoscopy at Kawasaki Medical School Hospital between January 2010 and December 2014. Inflammatory cells were counted in 1,000 μm2 fields of pyloric and fundic gland mucosal biopsy specimens. We finally included 325 (male, n = 141; female, n = 184; average age = 49.3 years) patients without inflammation who had H. pylori-negative endoscopic results and negative histological findings interpreted based on the updated Sydney System and the Kyoto classification of gastritis. Results: The average numbers of nucleated cells were 83.3 ± 14.2/mm2 and 65.4 ± 12.6/mm2 in the pyloric and fundic gland mucosae, respectively. Inflammatory cells were significantly more abundant in the pyloric mucosa than the fundic gland mucosa (p < 0.05). Age and sex distribution did not significantly differ. Eosinophils were absent or scanty in the gastric mucosae of both glands in all patients. Conclusion: We determined the absolute values of inflammatory cells, including eosinophils, in normal mucosae of pyloric and fundic glands. These findings could be important in defining gastric mucosal inflammation, including eosinophilic gastritis diagnosis.

Background: The prevalence of gastric polyps is unknown in Hungary. Aim: The aim of the authors was to assess the prevalence of polypoid lesions of the stomach in the endoscopic centre of the 2nd Department of Medicine, Semmelweis University. Methods: Results of upper gastrointestinal endoscopies carried out between March 2010 and June 2011 were analysed. Results: 193 cases with polyps were diagnosed in 4174 endoscopies (4.62%). Hyperplastic polyps, fundic gland polyps and malignant lesion were detected in 33.67%, 31.09% and 2.07% of the cases, respectively. Proton pump inhibitor use was more frequent among patients diagnosed with fundus gland polyps (p = 0.007), while hyperplastic polyps were diagnosed more frequently in patients with chronic gastritis (p = 0.032). Conclusions: The frequency of gastric polyps was higher than expected from data published in the literature. Long-term proton pump-inhibitor use and chronic gastritis were associated with fundus gland and hyperplastic polyps, respectively. Orv. Hetil., 2013, 154, 770–774.
