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.

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.

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.

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.

A gastric carcinoid is a rare disease that accounts for only 0.3% of all primary gastric tumors. It can be multiple or occur with other types of tumor. However, there has been a recent increase in incidence. While carcinoids of the appendix and rectum are accompanied by adenoma or adenocarcinoma, a gastric carcinoid rarely occurs with an adenocarcinoma, particularly with a gastric adenoma. We encountered a case of a gastric adenoma and carcinoid mixed as a composite tumor, which became a lesion. The lesion resembled a type IIc early gastric cancer at the endoscopic examination and was removed by an endoscopic mucosal resection. We report a composite tumor of the gastric antrum composed of areas of adenoma and carcinoid, with an analysis of the histological components by immunohistochemical staining. Microscopically, the lesion was composed of a gastric adenoma and carcinoid as a composite tumor.

BACKGROUND/AIMS: DA-9701 is a novel prokinetic agent. In the present study, we investigated the effect of DA-9701 on the motility of the gastric antrum in the normal and clonidine-induced hypomotility in an in vivo animal model. METHODS: A strain gauge force transducer was sutured on the gastric antrum to measure the contractile activity in rats. A total of 28 rats were subclassified into the 4 groups: (1) the placebo group, (2) the DA-9701 group, (3) the placebo group in the clonidine-pretreated rats, and (4) the DA-9701 group in the clonidine-pretreated rats. After the basal recording, either placebo (3% [w/v] hydroxypropylmethyl cellulose) or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. In the clonidine-pretreated rats, either placebo or DA-9701 was administered. Contractile signals were measured after the administration and after a meal. RESULTS: Oral administration of DA-9701 did not significantly alter the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the placebo group. The administration of clonidine decreased the motility index of the gastric antrum in the preprandial and postprandial periods, compared with the administration of placebo. This reduction of the antral motility by the administration of clonidine was not observed in the clonidine-pretreated DA-9701 group. The percentage of the motility index in the postprandial period was significantly greater in the clonidine-pretreated DA-9701 group, compared with the clonidine-pretreated placebo group. CONCLUSIONS: DA-9701 improves the hypomotility of the gastric antrum induced by clonidine, suggesting its gastroprokinetic effect in the pathologic condition.

The double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb. Some investigators postulate that the doubling of the pyloric channel is a congenital phenornenon, but others believe that it is an acquired lesion. A 72 year-old-man was admitted to this hospital because of epigastric pain for 1 month. Upper G-I series revealed thickened rnucosal folds of pylorus and duodenal bulb and dilated, deformed duodenal bulb filled with barium materials. Endoscopic findings also showed two ovoid large openings of the pyloric channel divided by smooth thickened septum and multiple gastroduodenal ulcers. We thought that this case was an acquired lesion. The relevant literatures on the subject were reviewed.

It is known that multiple ulcers of the gastric antrum are often accompanied by marked submucosal fibrosis during the healing process, and that this may result in a deformity of the gastric wall. Thus, benign antral ulcers may be misinterpreted as intramural tumors, or even malignant ulcers when the surrounding edema is pronounced and sharply defined. It is possible for an endoscopic ultrasonography (EUS) to detect which layer has a submucosal tumor (SMT) in the five-layer structures of the digestive tract wall. In the diagnosis of SMT of the upper digestive tract, EUS allows for the visualization of the structures underlying the gastrointestinal wall in a noninvasive manner and has a great advantage over conventional modalities such as endoscopy and X-ray examination. The EUS findings of 2 cases of submucosal tumor-like gastric lesion caused by fibrotic ulcer healing are herein reported with a brief review of relevant literature.
