| 1 | Gastric adenocarcinoma of the fundic gland(chief cell-predominant type): A review of endoscopic and clinicopathological features显示文摘Gastric adenocarcinoma of the fundic gland(chief cellpredominant type, GA-FG-CCP) is a rare variant of welldifferentiated adenocarcinoma, and has been proposed to be a novel disease entity. GA-FG-CCP originates from the gastric mucosa of the fundic gland region without chronic gastritis or intestinal metaplasia. The majority of GA-FG-CCPs exhibit either a submucosal tumor-like superficial elevated shape or a flat shape on macroscopic examination. Narrow-band imaging with endoscopic magnification may reveal a regular or an irregular microvascular pattern, depending on the degree of tumor exposure to the mucosal surface. Pathological analysis of GA-FG-CCPs is characterized by a high frequency of submucosal invasion, rare occurrences of lymphatic and venous invasion, and low-grade malignancy. Detection of diffuse positivity for pepsinogen-I by immunohistochemistry is specific for GA-FG-CCP. Careful endoscopic examination and detailed pathological evaluation are essential for early and accurate diagnosis of GA-FG-CCP. Nearly all GA-FG-CCPs are treated by endoscopic resection due to their small tumor size and low risk of recurrence or metastasis. | Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda | 2016 | World Journal of Gastroenterology2016，22，48： | 26 |
| 2 | Gastric adenocarcinoma of fundic gland type: Five cases treated with endoscopic resection显示文摘Recently,a new disease entity termed gastric adenocarcinoma of fundic gland type(GA-FG) was proposed.We treated five cases of GA-FG with endoscopic submucosal dissection.All tumors were small and located in the upper third of the stomach.Four tumors were macroscopically identified as 0-IIa and one was identified as 0-Ⅱb.Narrow-band imaging with magnifying endoscopy showed an irregular microvascular pattern in 2 cases and a regular microvascular pattern in the remainder.All tumors arose from the deep layer of the lamina propria mucosae and showed submucosal invasion.Lymphatic invasion was seen only in one case,while no venous invasion was recognized.All tumors were positive for pepsinogen-Ⅰ and MUC6 by immunohistochemistry.None showed p53 overexpression,and the labeling index of Ki-67 was low in all cases.All cases have been free from recurrence or metastasis.Herein,we discussed the clinicopathological features of GA-FG in comparison with past reports. | Masaki Miyazawa Mitsuru Matsuda Masaaki Yano Yasumasa Hara Fumitaka Arihara Yosuke Horita Koichiro Matsuda Akito Sakai Yatsugi Noda | 2015 | World Journal of Gastroenterology2015，21，26： | 16 |
| 3 | A pedunculated polyp-shaped small-bowel lymphangioma causing gastrointestinal bleeding and treated by double-balloon enteroscopy显示文摘We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI) bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE). An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital. She was suspected of having bleeding from the jejunum, and was referred to our department for diagnosis and treatment. An oral DBE revealed a 20 mm × 10 mm, regularly surfaced, white to yellowish, elongated, pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz. Since no other source of bleeding was identified by endoscopy in the deep jejunum, anendoscopic polypectomy (EP) was performed for this lesion. A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae. These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions. Although clip-ping hemostasis was performed during EP, re-bleeding occurred. Finally, a complete hemostasis was achieved by performing an additional argon plasma coagulation. | Akihiko Kida Koichiro Matsuda Satoshi Hirai Akiyoshi Shimatani Yousuke Horita Katsushi Hiramatsu Mitsuru Matsuda Hidero Ogino Shin Ishizawa Yatsugi Noda | 2012 | World Journal of Gastroenterology2012，18，34： | 5 |
