Abstract
The etiology of lower gastrointestinal bleeding is different in children from that of adults. The causes are usually simple, and require little or no treatment, for example, anal fissure, juvenile polyps, but sometimes these symptoms may indicate more severe and life threatening conditions. Once the bleeding is suspected to be coming from a lower GI source, it warrants an evaluation in all cases by procto-sigmoidoscopy followed by colonoscopy which is the examination of choice for diagnosis and treatment; it is also the most accurate method of imaging the lower gastrointestinal tract. This study was conducted on 75 patients (51 males & 24 females with age ranges from 3 years to 12 years) presented with lower gastrointestinal bleeding. All patients were collected from Pediatric Gastroenterology Unit, Pediatric Department, Menoufiya University Hospital in the period from 2010 to 201.
