BACKGROUND Previous studies of acute lower gastrointestinal bleeding (LGIB) have focused on evaluation and therapy. Measurement of long-term outcome has been rare. The purpose of this study was to document rebleeding and survival rates in patients with acute LGIB. METHODS A retrospective review of all patients undergoing technetium-labeled red blood cell scans for LGIB from January of 1997 to...

BACKGROUND Lower endoscopy (LE) is the standard diagnostic modality for lower gastrointestinal bleeding (LGIB). Conversely, computed tomographic angiography (CTA) offers an immediate non-invasive diagnosis visualizing the entire gastrointestinal tract. The aim of this study was to compare these 2 modalities with regards to diagnostic value and bleeding control. METHODS Tertiary center retrosp...

Lower gastrointestinal bleeding is defined as a bleeding originated from a source distal to the Treitz ligament and the colonoscopy is well established as the diagnostic procedure of choice. Objective: To evaluate the results of colonoscopies performed to diagnose the cause of acute lower gastrointestinal bleeding in a general hospital at Mato Grosso do Sul. Material and methods: Colonoscopy pr...

Dieulafoy lesion should be considered in massive gastrointestinal bleeding that may be difficult to localize. If the endoscopic and angiographic approaches fail, surgery must be considered according to the patient's clinical condition within an appropriate time. Although mostly seen in the stomach of old male patients with co-morbidities, here we presented a Dieulafoy lesion in the jejunum of a...

The primary study objectives were to estimate the frequencies and rates of gastrointestinal bleeding and peptic ulcerative disorder in HIV-positive patients compared with age- and sex-matched HIV-negative subjects. Data from a US insurance claims database was used for this analysis. Among 89,207 patients with HIV, 9.0% had a GI bleed, 1.0% had an upper gastrointestinal bleed, 5.6% had a lower g...

Lower GI bleeding (LGIB) is defined as bleeding that occurs from the bowel distal to the ligament of Treitz. The term ‘’lower gastrointestinal bleeding’’ is therefore a misnomer as it includes both small and large bowel bleed. Advent of capsule and double-balloon endoscopy has revolutionized the management of small bowel bleeding and it is accepted that small bowel bleeding represents a differe...

Autoerythrocyte sensitization syndrome CABS) is a rare purpuric disorder of women characterized by inflammatory and painful ecchymotic lesions unrelated to blood clotting or vascular abnormalities. Gastrointestinal bleeding, hematuria, headache or syncopal attacks may also be observed. Our patient is a 33-year-old woman presenting with recurrent severe painful ecchymotic lesions on both lo...

tc-99m pertechnetate scintigraphy is the modality of choice for diagnosis of meckel's diverticulum. interpretation of meckel's scan identifies a focal area of radiopharmaceutical uptake in the anterior abdomen similar to normal gastric mucosa. the activity must be of the same pattern and intensity as gastric uptake. we present a 13-year-old patient with gastrointestinal bleeding and anemia. tc-...
