Obscure gastrointestinal bleeding (OGIB) refers to gastrointestinal (GI) bleeding of unclear origin that persists or recurs after negative findings on esophagogastroduodenoscopy and colonoscopy. OGIB accounts for approximately 5% of all types of GI bleeding. More than 80% of OGIB cases originate in the small bowel. The ability to detect OGIB in the small bowel has significantly advanced and bee...

Clinical vignette: A 38-year-old man consults you in the GI clinic because of frequent episodes of epigastric pain, nausea, and tiredness. His blood count shows signs of mild iron deficiency anemia. Upper GI endoscopy was normal, but antral and corpus biopsy specimens show evidence of gastric atrophy and Helicobacter pylori infection. Colonoscopy and capsule endoscopy showed no evidence of lesi...

The recent breakthrough of technological innovation has contributed to a tangible advance in endoscopic imaging. Optical diagnosis is an indispensable diagnostic and therapeutic tool for gastrointestinal (GI) disease. Endocytoscopy opens the realm real-time microscopic evaluation GI tract, providing information about cellular subcellular changes during ongoing endoscopy, therapy potentially acc...

Gastrointestinal (GI) bleeding cases in whom source cannot be identified after conventional upper and lower GI endoscopy are defined as potential small bowel bleeding. We aimed to search for lesions in the reach of conventional endoscopy in patients to whom video capsule endoscopy (VCE) had been applied for potential small bowel bleeding. 114 patients who had VCE evaluation for potential small ...

AIM To investigate the association between a recent gastrointestinal (GI) endoscopy and the subsequent risk of pyogenic liver abscess (PLA). METHODS We designed a nested case control study. Using the Taiwan National Health Insurance Research Database, 2135 patients with a first diagnosis of PLA were identified from 1998 to 2011. Another 10675 patients without PLA matched by age and sex were s...

We read with interest the excellent editorial by Michael Jantz (January 2009) 1 that nicely summarized the existing data on the safety of propofol for pulmonary endoscopy. We would like to add that propofol also has an excellent record of safety for GI endoscopy. A recently published study documented the safety of propofolassisted sedation in . 500,000 patients undergoing various GI endoscopies...

BACKGROUND Data on safety of intravenous sedation in pediatric GI endoscopy are sparse. OBJECTIVE To evaluate safety of intravenous sedation for GI endoscopy. DESIGN/SETTING Single-center prospective series of outpatient GI endoscopies performed from February 2003 to February 2004 at The Children's Hospital of Philadelphia. The recorded information included demographic, medication, and adve...

Introduction Dyspepsia is a common symptom with an extensive differential diagnosis. Endoscopy alone may miss serious mucosal lesions in about 15 to 30% of cases. The aim was to determine histopathological features of gastric and duodenal mucosal biopsies in patients with dyspepsia and normal looking upper gastrointestinal (GI) endoscopy. Materials and methods One hundred and five adult patie...

BACKGROUND Levels of endoscopic demand and capacity in West Africa are unclear. OBJECTIVES This paper aims to: 1. describe the current labor and endoscopic capacity, 2. quantify the impact of a mixed-methods endoscopy course on healthcare professionals in West Africa, and 3. quantify the types of diagnoses encountered. METHODS In a three-day course, healthcare professionals were surveyed on...
