We experienced three young patients with diffuse lymphoid hyperplasia of the gastric antrum. The peculiar nodularity of the stomach in tliese patients is another cause of etat mammelanne in addition to hypertrophic gastritis and prominence of the areae gastricae. The etiology of the diffuse lymphoid hyperplasia of the gastric antrum is not known. The symptqm is not specific and not related to hitologic and gastroscopic finding but rather to psychological disturbance. We propose longstanding observation for the change of the nodularity.

Gastritis cystica profunda is an uncommon benign mass that usually occurs on the gastric side of the site of a gastroenterostomy, but has also been known to develop in which has not been operated on. We report the case of stomach a 51-years-old man with pathologically proven gastritis cystica profunda. This patient had not undergone gastric surgery and CT showed a well-defined, 3 cm sized, cystic mass at the gastric antrum.

Gastroduodenal intussusception is a rare condition and an invagination of a part of the gastric wall through the pyloric canal and into the duodenum. Gastroduodenal intussusception is always caused by a mobile gastric tumor, usually benign. However, gastroduodenal intussusception which was caused by gastric submucosal hemangiomatosis is not documented. We have maneged a case of gastric submucosal tumor leading to gastroduodenal intussusception in 2 years and 10 months old boy. He had a 10 x 5 x 3 cm sized submucosal tumor in posterior wall of gastric antrum. Laparotomy, manual reduction of intussusecption, and wedge resection of posterior gastric wall including the submucosal tumor were performed. Pathologic diagnosis showed a submucosal hemangiomatosis. We report a case of gastric submucosal tumor leading to gastroduodenal intussusception, and review the literature.

Double pylorus is a rare disease. It is described by a double communication between the gastric antrum and the duodenal bulb. The cause of double pylorus is either a congenital abnormality or an acquired condition. It is believed to be mostly a complication of peptic ulcer disease. Most reports revealed conditions only for the gastric antrum. However, case reports describing the involvement of the gastric body are extremely rare. Herein, we report a case of a double pylorus that developed on the gastric body and we present a review of the literature.

Gastroduodenal fistula or double pylorus is a very rare condition. It is a fistulous communication between gastric antrum and duodenal bulb. It can be either congenital or acquired. In most cases it is thought to be a complication of gastric ulcer. We recently experienced a case of gastroduodenal fistula in 70 year-old man presenting as epigastric pain. He was diagnosed with non ST elevation myocardial infarction previously, and was taking aspirin. Gastroduodenal communication was revealed by endoscopy. We report a case of gastroduodenal fistula that developed in man who was taking aspirin, with review of the literature.

Gastric antral vascular ectasia ("watermelon stomach") is characterized by a prominent longitudinalerythematous fold of gastric antrum. Because it has usually been diagnosed by gastroscopy and biopsy, itsradiologic findings have not been well described. We report a case of gastric antral vascular ectasia, anddescribe its findings, as seen on UGIS, ultrasonography, and computed tomography.

Gastric lipoma is a typical benign submucosal tumor that is usually asymptomatic and is generally detected incidentally when performing gastroscopy. However, depending on its size and location, an atypical gastrointestinal lipoma can cause abdominal pain, diarrhea, constipation, intestinal obstruction, intussuception and life-threatening gastrointestinal bleeding. We report herein a case of gastric lipoma with bleeding in a 43-year-old man. The gastroscopy showed a 4x4 cm ulcero-fungating submucosal mass at the anterior wall of the gastric antrum. Laparoscopic gastric wedge resection was performed and the lesion was diagnosed as gastric lipoma.

BACKGROUND: The purpose of this study was to investigate the ultrastructural relation of H. pylori and gastric epithelial cells in their adhesion. METHODS: Endoscopic biopsy of gastric antrum and body was performed from 15 patients (9 men, 6 women) with chronic gastritis. These specimens were processed and observed by transmission electron microscope (Hitachi H-600). RESULTS: On the basis of morphological appearances, the different types of adhesion of the organism with the epithelial cells were categorized as filamentous connection, adhesion pedestals, membrane fusion. Coccoid and intermediate forms were associated with filamentous connection whereas bacillary forms were associated with adhesion pedestals and membrane fusion. CONCLUSION: Various types of adhesion were associated with H. pylori and gastric epithelium. Further studies are needed to investigate biophysiologic influence to epithelial cells by ultrastructural relationship.(Korean J Med 60:16-21, 2001)

PURPOSE: To demonstrate the two-phase spiral CT features of pseudo-wall thickening and tumor in the gastricantrum, and to evaluate the possibility of differential diagnosis by analyzing two-phase spiral CT scans. MATERIALS AND METHODS: We retrospectively reviewed 120 cases in which two-phase spiral CT scans showed focal wallthickening in the prepyloric antrum of the stomach. Our series included 60 cases of gastric cancer (includingseven of early gastric cancer) and 60 cases of normal prepyloric antrum. All patients underwent two-phase spiralCT and upper gastrointestinal series (n=83) and/or gastric endoscopy (n=80). All cancer cases were confirmed bybiopsy (n=60). We evaluated the differential points between gastric cancer and pseudo-wall thickening of thegastric antrum. RESULTS: The mean thickness of the antral wall was 19.0mm in the cancer group and 12.5mm in thenormal group. Thirty-one cases (51.7%) in the cancer group and 51 (85.0%) in the normal group showed concentricwall thickening, while in each group, the remainder showed eccentric wall thickening. The common enhancementpatterns of thickened wall in the cancer group were 1) a thick enhanced mucosal layer during the arterial phase,with diffusely enhanced whole wall thickness during the venous phase (n=21); 2) a thick enhanced mucosal layerduring the arterial phase, with thicker and more intense enhancement of the same area during the venous phase(n=18). In the normal group, the common enhancement pattern was a thin enhanced mucosal layer during both thearterial and venous phase (n=34). In the cancer group, the common associated findings were regionallymphadenopathy (n=43) and food remnants in the stomach (n=15), and in the normal group, intraluminal normalmucosal folds in the thickened segment (n=50). The findings of food remnants despite overnight fasting andintraluminal normal folds occurred only in the cancer and normal group, respectively. CONCLUSION: Pseudo-wallthickening frequently showed thin enhancement of the mucosal layer on both the arterial and venous phases oftwo-phase spiral CT scan; a tumor frequently showed a thick enhanced mucosal layer during the arterial phase, withdiffusely enhanced whole-wall thickness during the venous phase or a thick enhanced mucosal layer during thearterial phase, with thicker and more intense enhancement of the same area during the venous phase. The finding ofthin and homogeneously enhanced intraluminal normal mucosal folds in the thickened segment strongly suggested thatthe lesion was a pseudo-lesion.

BACKGROUND: Helicobacter pylori is present mainly in the gastric mucous layer. However, the mucous layer, along with the bacteria, is lost during conventional tissue processing in which formalin is used for fixation. The purpose of this study is to ascertain - if the mucous layer is preserved by using Carnoy solution as a fixative - whether the detection rate of H. pylori is increased in pediatric patients. METHODS: Five pieces of gastric mucosal tissue were obtained from the gastric antrum and the body of one hundred pediatric patients. One of the specimens was fixed with formalin. Another specimen was fixed with Carnoy solution. The tissue sections were stained with hematoxylin-eosin and immunohistochemically stained for H. pylori. For reference, a rapid urease test was performed on the remaining three specimens. RESULTS: In the formalin-fixed tissue, the detection rate of H. pylori was 13% in the gastric antrum and 12% in the body (overall 16%). In the Carnoy solution-fixed tissue, the mucous layer was preserved and the detection rate of H. pylori was 23% in the antrum and 27% in the body (overall 28%). The positive rate of the rapid urease test was 26% in the antrum and 28% in the body (overall 29%). CONCLUSIONS: When the number of H. pylori is small in the gastric mucosa, the bacteria may not be detected by conventional histologic methods. In that case, the detection rate of H. pylori may be increased by using Carnoy solution, rather than formalin, as a tissue fixative.
