Abstract

Small bowel follow through (SBFT) and enteroclysis have low sensitivity in picking up lesions in obscure gastrointestinal bleed (OGIB). Computed tomographic enterography (CT-EG), performed with 64-slice multiphase CT system by using large volumes of ingested neutral enteric contrast material, has high spatial and temporal resolution in visualization of the small bowel wall and lumen. The role of 64-slice multiphase CT-EG in the evaluation of OGIB is still evolving, and data on this role are scarce. We evaluated the efficacy of 64-slice multiphase CT-EG using polyethylene glycol (PEG) electrolyte solution as neutral contrast in patients of OGIB. CT-EG was performed with 64-slice multiphase CT system using large volume (2,000 mL) of PEG electrolyte solution as oral contrast in patients of OGIB. Thirty-five patients (21 men, age 41.4 [13.5] y, range 19-70 year) with OGIB underwent CT-EG; 20 patients had overt OGIB whereas 15 patients had occult OGIB. Among 15 patients with occult OGIB, 10 patients had iron deficiency anemia (IDA) with fecal occult blood test (FOBT) positive and 5 had IDA with FOBT negative. Thirty-two patients (92 %) completed the procedure successfully. The total time taken for the ingestion of 2,000 mL of PEG el...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
