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.

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.

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.

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.

Double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb; in most cases it is a complication of penetrating ulcer, and sometimes it is a congenital abnormality. The prevalence of this rare anomaly ranges from 0.02% to 0.13%; the male: female ratio is about 2: 1. A case of double pylorus, in 41 year-old male, was diagnosed by gastrofiberscopy and UGIS. Two ovoid and crescent pits of the pyloric canal divided by smooth thickened septum were observed endoscopically. The upper GI series showed gastroduodenal fistula connecting the leeser curve of distal antrum with the duodenal bulb. The relevant literatures on the subject were reviewed.

Although most persons infected with Helicobacter pylori harbor a single strain of the organism, multiple strain colonization in the same patient is also occasionally reported in developed countries. The aims of this study were to determine the prevalence of multiple strain colonization in Korean patients and to detect the cagA, iceA1, and babA status of H. pylori isolated from the antrum and body of the stomach. H. pylori was obtained from 35 patients from the antrum and body of the stomach. The genomic diversity of H. pylori was determined by random amplified polymorphic DNA analysis. The status of cagA, iceA1, and babA genes of H. pylori was assessed by polymerase chain reaction with appropriate primers. Clearly different diversity patterns were identified among the isolates from 35 individual patients. Eighteen (51.4%) patients had a single strain of H. pylori. Eight (22.9%) and nine (25.7%) patients had subtypically (one or two bands difference) and typically (clearly different pattern) different strains of H. pylori in the antrum and body, respectively. Among the 70 isolates of H. pylori from 35 patients, the positive rates of 349-bp and 208-bp cagA gene fragments and the iceA1 gene were 68/70 (97.1%), 68/70 (97.1%), and 58/70 (82.9%), respectively. However, the babA gene was found in 22/66 cases (31.4%). In five out of 18 patients with a single strain, the genetic status of cagA, iceA1, and babA varied between the isolates from the antrum and the body. In 8/17 patients with subtypically or typically different strains, the gene status differed between antrum and body isolates. The prevalence of co-colonization with typically or subtypically different strains is high in Korea, and sub-clones with different pathogenic gene status exist within strains of identical RAPD patterns.

Malignant transformation of heterotopic pancreas is extremely rare. We report a case of ductal adenocarcinoma arising from heterotopic pancreas in the stomach of a 64-year-old man. Preoperative CT scans showed the lesion as a submucosal mass along the greater curvature of the pyloric antrum and protruding into the pyloric canal. After gastric surgery, the resected tumor was histopathologically diagnosed as a ductal adenocarcinoma arising from heterotopic pancreas with cystic dilatation of aberrant pancreatic duct.
