An 80-year-old woman presented with recurrent occult gastrointestinal bleeding requiring blood transfusions. She underwent endoscopy and colonoscopy that failed to identify the cause of bleeding. An enteroscopy revealed duodenal arteriovenous malformation that was cauterized. However, anemia and occult gastrointestinal bleeding recurred. A repeat enteroscopy was negative. A wireless capsule end...

An 86-year-old woman with a history of cardiac and chronic renal failure was referred to our gastroenterology outpatient clinic because of an iron deficiency anemia and intermittent, self-limited hematochezia episodes. Colonoscopy and upper endoscopy revealed no alterations. A capsule endoscopy showed a nonbleeding angioectasia in the proximal ileum. Single-balloon enteroscopy was proposed to t...

Conventional algorithms for diagnosis and treatment of gastrointestinal bleeding (GIB) in patients with nonpulsatile ventricular assist devices (VADs) may take days to perform while patients require transfusions. We developed a new algorithm based on deep overtube-assisted enteroscopy (DOAE) to facilitate a rapid diagnosis and treatment. From 2004 to 2012, 84 patients who underwent VAD placemen...

Enteropathy-type T-cell lymphoma (ETL) is a rare primary intestinal disorder, particularly in Japan, and there have been few reports on the endoscopic findings of the disease. Here we report detailed endoscopic findings of ETL based on double-balloon enteroscopy and capsule endoscopy. Double-balloon enteroscopy and capsule endoscopy may be useful tools for diagnosing and monitoring the effects ...

Management of small bowel diseases has evolved since the advent of capsule endoscopy (CE) and balloon-assisted enteroscopy (BAE). One of the most common indications for enteroscopy is obscure gastrointestinal bleeding (OGIB), followed by small bowel stenosis, tumors, and inflammatory bowel disease. Although enteroscopes have been regarded as useful tools, correct guidelines are required to ensu...

BACKGROUND Occult gastrointestinal blood loss is generally investigated with colonoscopy and esophagogastroduodenoscopy in patients with iron-deficiency anemia. The aim of this study was to prospectively measure the additional diagnostic yield of examining the jejunum at the time of upper endoscopy in patients with iron-deficiency anemia. METHODS Asymptomatic patients with newly diagnosed iro...

SG The through-the-scope balloon system consists of a balloon catheter that is placed through the end of a colonoscope and allows the endoscopist to advance deep into the small intestine via the stomach or the colon. The balloon is pushed out in front of the colonoscope, anchored in the small bowel, and inflated. Through a series of balloon inflations and deflations, the colonoscope advances al...
