Capsule Endoscopy in Iron Deficiency Anaemia

IDA is common and 90-95% of cases are caused by bleeding from ulcers, tumours or vascular malformations in the oesophagus, stomach, duodenum, small intestine or the large bowel.Bleeding from more than one localisation is common. International guidelines recommend bidirectional endoscopy(gastro- and colonoscopy) to detect and treat the source of bleeding. Our hypothesis is that WCE is non-inferior to the combination of gastroscopy and colonoscopy in locating GI-bleeding and that complete examinations will be achieved in ≥90% of the examinations.
