Faecal calprotectin and ultrasonography as non-invasive screening tools for detecting colorectal polyps in children with sporadic rectal bleeding. a prospective study
Background: Colorectal polyps are reported in 6,1% of paediatric colonoscopies and in 12% of those performed for
lower gastrointestinal bleeding. Although colonoscopy is widely used in paediatric patients, it requires bowel
preparation and general anaesthesia or deep sedation, and in rare cases, it can cause complications. Non-invasive
screening techniques able to predict polyps in children with isolated and sporadic rectal bleeding may play a key
role in the selection of patients needing colonoscopy.
