En-bloc resection is desirable for accurate histopathological assessment of tissue specimens obtained using endoscopic mucosal (EMR). A new EMR method sodium hyaluronate and a small-caliber-tip transparent hood has been developed. This peeling-off needle-knife submucosal incisions. Long-lasting thickening resulting from an injection hyaluronate, good visualization the with aid hood, make cutting procedures easy safe. large superficial gastric cancer villous tumor sigmoid colon were...
Management of small bowel diseases has evolved since the advent capsule endoscopy (CE) and balloon-assisted enteroscopy (BAE). One most common indications for is obscure gastrointestinal bleeding (OGIB), followed by stenosis, tumors, inflammatory disease. Although enteroscopes have been regarded as useful tools, correct guidelines are required to ensure that we manipulate these safely efficiently in clinical practice. Herein, Japanese Gastroenterological Endoscopy Society developed 'Clinical...
OBJECTIVES: To evaluate the utility and safety of a short-type double-balloon endoscope (DBE) in treatment biliary disease patients with surgically altered gastrointestinal (GI) anatomy. METHODS: This study was conducted as multicenter, single-arm, prospective trial at five tertiary academic care centers three community-based hospitals Japan. Consecutive GI anatomy were prospectively included this study. RESULTS: A total 311 underwent endoscopic retrograde cholangiography (ERC). The success...
Objective. Capsule endoscopy has shown that non-steroidal anti-inflammatory drugs (NSAIDs) can damage the small intestine. The aim of this study was to determine prevalence NSAIDs enteropathy in subjects indicated for double-balloon (DBE). Material and methods. Japanese Study Group Double-Balloon Endoscopy (JSG-DBE) established a database practical use DBE population during 2-year period from 2004 2005. Using database, we identified who had been taking within month prior (NSAIDs group) those...
Crohn's disease (CD) strictures of the small intestine are a feared complication and difficult to treat because difficulty gaining access stricture site. The development double-balloon endoscopy (DBE) enabled entire with interventional capabilities. aim this study was assess long-term outcomes in patients intestinal secondary CD after DBE-assisted endoscopic balloon dilation (EBD).In retrospective cohort study, EBD performed 85 consecutive from 2002 2014. Follow-up data were available for...
Dysbiotic microbiota contributes to the pathogenesis of Crohn's disease (CD) by regulating immune system. Although pro-inflammatory microbes are probably enriched in small intestinal (SI) mucosa, most studies have focused on fecal microbiota. This study aimed examine jejunal and ileal mucosal specimens from patients with CD via double-balloon enteroscopy. Comparative microbiome analysis revealed that composition SI mucosa differs non-CD controls, an increased population several families,...
The safety and efficacy of double-balloon enteroscopy (DBE) in pediatric patients has not been well documented. We aimed to evaluate the clinical DBE children, especially those under 10.We retrospectively analyzed our database procedures performed between September 2000 2013. Procedures (under 18) were selected from a total 3980, including endoscopic retrograde cholangioscopy (DBERC).Two hundred fifty-seven 117 (median age 12.5 years). Antegrade (oral-route) was 166 104 DBERC (lowest body...
During endoscopy, especially in patients with gastrointestinal bleeding, it is often difficult to secure the visual field. Although water immersion techniques are sometimes used mitigate this situation [1] [2] [3], maintenance of field because infused/injected rapidly mixes any luminal blood and/or residue. Poor preparation before colonoscopy also makes when using or exchange techniques. The use gas insufflation displace contents can cause significant discomfort and endoscope insertion. It...
Abstract Objectives Patients with Peutz–Jeghers syndrome (PJS) require continuous medical management throughout their lives. However, few case series regarding the clinical course, polyp surveillance, and treatment, including endoscopic ischemic polypectomy (EIP) for pediatric patients PJS, were reported. We analyzed current status course of PJS under our institute, those treated EIP. Methods Medical information on double‐balloon enteroscopy (DBE) performed between January 2006 December 2023...
Underwater endoscopic mucosal resection (UEMR) is the standard method for superficial non-ampullary duodenal tumors (SNADETs). We developed a novel UEMR technique that creates an anchor by protruding distal fold with saline injection (UEMR-A). The aim of this study was to clarify usefulness UEMR-A compared conventional (UEMR-C). This retrospective observational included patients who underwent SNADETs. A total 141 were and divided into (n=54) UEMR-C (n=87) groups. Lesion performed...
Background Esophageal stricture causes severe distress to patients. However, there are no established treatments for refractory esophageal anastomotic endoscopic balloon dilation (EBD). Steroid injection added EBD and radial incision cutting (RIC) effective such strictures, but it is unclear which more effective. The objective of this study was investigate the safety efficacy RIC with steroid compared patients after esophagectomy. Methods This a multicenter, randomized phase II/III trial....
