Purpose: Laparoscopic wedge resection of gastric submucosal tumor may be difficult in case of the endophytic mass or the mass located unreachable area such as cardia, and intragastric approach can be useful. We would present the experiences of the intragastric wedge resection. Materials and Methods: There were 7 patients diagnosed as gastric submucosal tumor and underwent the intragastric wedge resection at Surgery, Chungnam National University Hospital. We reviewed medical record. Results: There were 3 male and 4 female. Mean age was 65 years-old (57~73). Mean body mass index was 26.28 kg/$m^2$ (21.28~35.30). Location of lesions was 4 cardia, 2 fundus and 1 midbody, respectively. Mean operation time was 83.6 minutes (70~105). All patients were healed without any complication. Mean postoperative hospital stay was 5.4 days (4~6). Mean size was 2.7 cm (2.3~3.8). Pathologic finding was 5 gastrointestinal stromal tumor and 2 leiomyoma. Conclusions: The single incision intragastric wedge resection of gastric submucosal tumor is feasible and acceptable, especially in mass of gastric upper part.

Gastric wall abscess, a localized form of phlegmonous gastritis, is a rare complication of endoscopic resection. We report the first case of gastric wall abscess developing after endoscopic submucosal dissection in Korea. A 72-year-old woman visited our clinic to receive treatment for gastric adenoma. The patient successfully underwent endoscopic submucosal dissection with no complications. The final diagnosis was well-differentiated tubular adenocarcinoma. We performed follow-up endoscopy 10 weeks later and found a large subepithelial lesion on the posterior wall of the gastric antrum. Abdominal computed tomography revealed hypodense wall thickening and a 5 cm heterogenous multilobular mass in the submucosal layer of the gastric antrum. Submucosal invasion with mucin-producing adenocarcinomas could therefore not be excluded. The patient agreed to undergo additional gastrectomy due to the possibility of a highly malignant lesion. The final diagnosis was acute suppurative inflammation with the formation of multiple abscesses in the mural layers and omentum. The patient was discharged with no complications.

Anisakiasis is a parasitic disease caused by ingestion of raw fish infected with anisakid larvae. Endoscopic changing patterns of submucosal lesions in chronic gastric anisakiasis have not been known yet. Here we report 4 cases of suspected gastric anisakiasis which were improved during follow-up periods without surgical treatment. The patients presented with abdominal pain, nausea and vomiting after consuming raw marine fish, and visited our gastroenterology outpatient department. Their endoscopic findings showed firm and yellowish submucosal masses accompanied with eccentric erosions. Histologic findings showed severe eosinophilic infiltrations. In blood tests, peripheral eosinophil counts and total IgE levels were elevated. We believed that all cases were caused by larval anisakid infections. The submucosal mass lesions disappeared during the follow-up periods of 2 to 4 mo.

Co-existing pyloric submucosal masses with hypertrophic pyloric stenosis (HPS) are very rare and treating these lesions is always a problem. A 20-day-old boy presented with recurrent episodes of projectile non-bilious vomiting lasting for 5 days. HPS was suspected due to the presenting age and the symptoms. The sonography demonstrated not only circumferential wall thickening of the pylorus, but also a pyloric submucosal mass. At laparotomy, a 0.8 cm sized pyloric submucosal mass was identified along with a hypertrophied pylorus. Pyloric excision was performed due to the possibility of sustaining the symptoms and malignancy. The pathological report of the submucosal mass was ectopic pancreas. Coexisting pyloric lesions can be diagnosed along with HPS, and surgical excision, not just pyloromyotomy, should be considered in these circumstances. To the best of our knowledge, this is the first case report of pyloric ectopic pancreas and HPS to be diagnosed concurrently.

저자들은 위의 하부 체부에 지방 성분으로 둘러싸여 있는 분엽성 형태의 점막하 종괴로 나타난 이소성 췌장의 1예를 경험하였다. 지방 성분을 포함한 이소성 췌장은 매우 드물지만, 이 증례를 바탕으로 병변 주위 지방 침윤을 보이는 위 점막하 종괴가 있을 때 이소성 췌장의 가능성을 감별해야 하므로 이를 보고하는 바이다.

Gastric glomus tumor is a rare mesenchymal tumor that originates from modified smooth muscle cells of the glomus body. Glomus tumors are commonly observed in peripheral soft tissue, such as dennis or subungal region, but rarely in the gastrointestinal tract. A 39-year-old woman was admitted due to epigastric soreness. Upper gastrointestinal endoscopy revealed a subepithelial mass measuring 3.5 cm with central ulceration at the lesser curvature-posterior wall of the antrum. Characteristically, contrast enhanced abdominal computed tomography scan demonstrated high enhancement of the submucosal mass up to the same level of the abdominal aorta in the arterial phase; this enhancement persisted to delayed phase. Due to the risk of bleeding and malignancy, wedge resection of the submucosal tumor was performed. Histologic findings were compatible with a glomus tumor.

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 $4{\times}4$ 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.

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.

We describe a case of a 48-year-old Korean woman who had a subepithelial mass incidentally discovered by endoscopic examination. Endoscopic mucosal resection revealed a well-circumscribed whitish solid mass within the submucosal space. Microscopically, the tumor was comprised of sparse spindle cells in the dense collagenous stroma with several calcifications and lymphoid aggregates. Immunohistochemical analysis showed that the tumor cells are negative for c-kit, smooth muscle actin, desmin, S-100 and CD34. Based on these findings, the tumor was diagnosed with calcifying fibrous tumor.

암컷, 8년령, 3.2 kg의 시츄견이 간헐적인 구토를 주증으로 내원하였다. 기본 혈액검사 및 방사선 검사에서 특별한 이상 소견은 관찰되지 않았다. 복부 초음파 검사에서 위벽에서 유래한 것으로 생각되는 저에코의 둥근 종괴가 관찰되었다. 위 내시경 검사에서 둥근 종괴가 유문동 벽에서 내강으로 돌출되어 있고, 종괴 및 주변 점막의 비정상적인 소견은 관찰되지 않았다. 이에 위 종괴 절제술을 실시하였고, 면역 염색을 포함한 조직학적 검사에서 extramedullary plasmacytoma로 진단되었다. 환자는 임상 증상이 개선되었으며, 약 2년 동안 재발 및 전이 소견 없이 건강한 상태이다.
