Gastric lipomatosis is an extremely rare condition. We present a case of a 69-year-old woman admitted with epigastric soreness. Computerized tomography (CT) revealed extrinsically compressing, fat-containing mass lesions on the entire gastric wall of the antrum and body except for the lesser curvature. A subtotal gastrectomy was performed. Pathology findings confirmed a gastric lipomatosis with multiple gastric ulcerations and extensive disruptions of the muscular layers. This case and reports of other gastric lipomatosis cases indicate that CT should be used to characterize large submucosal masses because CT can show the specific nature and extent of the disease. We believe that surgical treatment is the most appropriate treatment for symptomatic gastric lipomatosis that shows extensive gastric involvement, or when there are multiple gastric lipomas.

Background: Treatment of Helicobacter pylori (H. pylori) decreases the prevalence of gastric cancer, and may inhibit gastric precancerous lesions progression into gastric cancer. The aim of this study was to determine the effect of treatment on subsequent gastric precancerous lesion development. Materials and Methods: We prospectively studied 27 patients who had low grade dysplasia at the time of enrollment, in addition to dysplasia atrophic gastritis and intestinal metaplasia observed in all patients. All were prescribed quadruple therapy to treat H. Pylori infection for 10 days. Patients underwent endoscopy with biopsy at enrollment and then at follow up two years later. Biopsy samples included five biopsies from the antrum of lesser curvature, antrum of greater curvature, angularis, body of stomach and fundus. Results of these biopsies were compared before and after treatment. Results: Overall, the successful eradication rate after two years was 15/27 (55.6%). After antibiotic therapy, the number of patients with low grade dysplasia decreased significantly (p=0.03), also with reduction of the atrophic lesions (p=0.01), but not metaplasia. Conclusions: Treatment of H. pylori likely is an effective therapy in preventing the development of subsequent gastric premalignant lesions.

Gastroduodenal intussusception, an invagination of a part of the gastric wall through the pyloric canal into the duodenum is a rare condition. Gastroduodenal intussusception is caused by a mobile usually benign gastric tumor. However, gastroduodenal intussusception by gastric submucosal hemangiomatosis is not documented. We have managed a case of gastric submucosal tumor leading to gastroduodenal intussusception in 2 years and 10 months old boy. The tumor was $10{\times}5{\times}3cm$ in size in posterior wall of gastric antrum. Laparotomy, manual reduction of the intussusception, and wedge resection of posterior gastric wall including the tumor were performed. Pathologic diagnosis was a submucosal hemangiomatosis.

We report a case of long term survival on trastuzumab based treatment. A 51-year-old man with dyspepsia received esophagogastroduodenoscopy on another hospital and was transferred for further evaluation under the impression of advanced gastric cancer, Borrmann type III, antrum, lesser curvature. After further studies in our hospital, the patient was diagnosed with advanced gastric cancer, adenocarcinoma, moderately differentiated with pancreas invasion and lymph node metastasis. Though he was recommended with chemotherapy, he refused and left for oriental herbal medicine. After 4 months, the patient was admitted through emergency room for hematemesis. Diagnosed with gastric outlet obstruction due to gastric cancer in the antrum, he underwent the placement of pyloric metal stent insertion. Immunohistochemical staining showed HER2-positive finding, and he was treated with palliative chemotherapy of trastuzumab, capecitabine, and cisplatin, 16 times during 11 months. The patient showed neutropenia after the therapy, so cisplatin was left out, and he received combination chemotherapy of trastuzumab and capecitabine, 34 times during 25 months. Response evaluation showed no remarkable change in extent of primary stomach cancer, lymph node metastasis, and regression of metastasis site, and the patient is continuing chemotherapy.

Neurofibromas are benign tumors that originate from the peripheral nerves, including neurites and fibroblasts. Generally, a solitary neurofibroma is located in the skin and rarely in other places. A 72-year-old female suffered from epigastric discomfort for 2 months. Endoscopic findings showed an early gastric cancer type IIc at the antrum. Abdominal computed tomography revealed early gastric cancer with a 1.6 cm-sized metastatic node posterior to the duodenum. Laparoscopic assisted distal gastrectomy and retro-pancreatic dissection were performed uneventfully. Histological examination revealed gastric adenocarcinoma, invading the mucosa without nodal metastasis, and a neurofibroma. Herein, we present a case of a gastric cancer patient with a solitary retroperitoneal neurofibroma which mimicked a distant metastatic node.

Gastric metastasis from ovarian carcinoma is extremely rare and the prognosis for patients is poor. We report a case of multimodal treatment improving the survival time of a patient with gastric metastasis from ovarian cancer. A 73-year-old woman with known serous ovarian cancer was admitted to the hospital due to epigastric pain and dyspepsia. On esophagogastroduodenoscopy, a protruding mass was noted at the gastric antrum. She underwent distal gastrectomy with Billroth I anastomosis and lymph node dissection, including the para-aortic lymph nodes. The final pathology revealed gastric metastasis from ovarian serous adenocarcinoma. In this case, after cytoreductive surgery, chemotherapy was performed each time a recurrence was diagnosed, and remission was accomplished. She survived for 108 months after the first diagnosis of the metastatic tumor in the stomach. Multimodal treatment of metastatic lesions since the first diagnosis allowed the patient to survive longer than those in previous reports.

Helicobacter species have been identified in or isolated from domestic carnivores, but their prevalence in different population of animals and their clinical significance are still unknown. This study was peformed to evaluate the prevalence of Helicobacter in clinically healthy dogs by urease test, culture, morphological examination and polymerase chain reaction (PCR) technique. Tissue samples from 70 dogs in Kangwon and Kyunggi areas from August 1998 to April, 1999, were examined. The detection rates of Helicobacter by urease activity of tissue-samples were 84.6%, 61.3% and 4.8 % in the fundus, the antrum and the duodenum, respectively. One strain of Helicobacter was isolated from the duodenum. It was identified as H canis by biochemical and morphorogical examination. The detection rates of Helicobacter by histological examination were 92.3%, 79.0% and 4.8% in the fundus, antrum and the duodenum, respectively. Helicobacter organisms were colonized more in the gastric pits than in the surface of epithelium, the gastric gland or the parietal cell. Although most of dogs were colonized with Helicobacter in tissue, gross lesions and specific histopathological lesions caused by Helicobacter in these tissues were not observed. The detection rate of Helicobacter by PCR was 78.6%. The histological examination was more sensitive than urease test, culture or PCR technique for the detection of Helicobacter.

Antral web is a rare cause of gastric outlet obstruction in neonate. It is a 2-4 mm thin mucous membrane that can be found anywhere from 1 to 7 cm proximal to the pylorus. The baby was born at gestational age of $32^{+1}$ weeks with 1,880 g as 2nd baby of dizygotic twin. After birth, the baby had constant non-bilious vomiting without feeding while he didn't show abdominal distension or discoloration. The infantogram showed distended stomach with distal small bowel gas. Upper gastrointestinal series revealed that the antrum was abruptly narrowed at 1 cm proximal to pylorus. We performed laparotomy at the 10th day after birth and excised the 2 mm-thick web circumferentially. He began milk feeding after 6 days and discharged uneventfully at postoperative 35 days with corrected age of $38^{+4}$ weeks with body weight 2,420 g. The antral web should be considered in the case of non-bilious vomiting in neonate.

Early gastric cancer (EGC) is defined as a carcinoma confined to the mucosa or submucosa of the stomach, with or without lymph-node metastasis. Synchronous liver metastasis is 5. $12.8\%$ in advanced gastric cancer, but is very low in EGC. A 64-year-old woman was admitted to St. Vincent's Hospital with a complaint of epigastric pain. Gastrofiberscopic examination showed a polypoid mass on the gastric antrum. Abdominal computed tomography demonstrated an intraluminal polypoid mass in the gastric antrum, but no tumor mass in the liver. A laparotomy revealed a solitary liver metastasis, we performed a distal partial gastrectomy with a group-2 lymph-node dissection and resection of metastatic liver tumor. Histologic examination showed a tubular adenoma with a focal carcinomatous change, Which was confined to the gastric mucosa and to the metastatic adenocarcinoma in the liver. We present a case of early gastric mucosal cancer associated with synchronous liver metastasis, along with a review of the literature.

The aim of this report is showing the case that we could give exact navigation of perigastric vessels for gastrectomy with 3D CTA. A 74-year-old male patient visited hospital with gastric cancer. Early gastric cancer, type IIb was found at stomach antrum great curvature side. Before surgery, he underwent 3D CT angiography. 3D volume rendering images and MIP images were made by post processing. He had replaced Lt. hepatic artery arising from Lt. gastric artery. Surgeon could get patient's specific vascular anatomy before surgery including surgically relevant anatomical distance and direction and could finish gastrectomy within 4 hours and just 53ml blood loss.
