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(More)
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(More)
BACKGROUND Recently, a method for detecting Helicobacter pylori-specific antigens in the stool (HpSA) has been proposed to be useful clinically. The aim of this study was to determine the accuracy of HpSA for the diagnosis of H. pylori infection, including early assessment after eradication treatment, and the potential for quantitative evaluation of H.(More)
A mass lesion presenting difficulty in differential diagnosis between a tumor in the lateral segment of the liver and a gastric submucosal tumor (SMT) was found in a 59-year-old man with chronic hepatitis B. For differential diagnosis between the 2 lesions, endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) was performed. EUS showed a tumor(More)
We herein describe the case of a 68-year-old man who developed overt diabetes mellitus following the topical administration of dexamethasone 0.1%-containing ointment over a five-month period to treat oral lichen planus. The topical dexamethasone therapy was discontinued gradually, and the patient was subsequently treated with insulin for one month without(More)
A 71-year-old man with diabetes mellitus visited our hospital with complaints of anorexia and weight loss (12 kg/3 months). He had megaloblastic anemia, cobalamin level was low, and autoantibody to intrinsic factor was positive. He was treated with intramuscular cyanocobalamin, and he was able to consume meals. GAD autoantibody and ICA were positive, and he(More)
Gastric adenocarcinoma of the fundic gland (chief cell-predominant type, GA-FG-CCP) is a rare variant of well-differentiated 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(More)
