The Use of Robot Assisted Magnetically Controlled Capsule Endoscopy in Patients With Iron Deficiency Anaemia

In this study the investigators will recruit patients who have already had an upper gastrointestinal (GI) tract endoscopy (OGD) and lower GI tract investigations which did not identify the source of iron deficiency anaemia, and who need the small bowel to be investigated. This will comprise both patients who would have proceeded directly to small bowel capsule endoscopy (SBCE) under standard care and also those from whom an initial 'watch and wait' approach may have been adopted before proceeding to SBCE. The investigators propose to investigate these patients during a single patient visit to Leith Community Treatment Centre, Edinburgh, Scotland, with a CE marked robotic capsule system which can examine both the upper GI tract (i.e. the oesophagus and the stomach) and the small bowel in one investigation using a magnetic guided capsule. The aim of the study is to compare the findings from OGD with the robotic capsule system and to determine if such a system may safely replace OGD - thus examining the upper GI tract and small bowel for IDA in one less invasive investigation. This has the potential to decrease patient discomfort, stress and anxiety, while also reducing pressure on busy endoscopy departments, helping to ensure that the right patients receive the right investigations in a timely manner.
