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

Not Applicable

Not yet recruiting

• Conditions: Iron Deficiency Anaemia

• Registration Number: NCT07197424
• Lead Sponsor: University of Edinburgh

Brief Summary

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.

Primary Outcome Measures

Name	Time	Method
Non-inferiority of robot assisted magnetically controlled capsule endoscopy compared to upper GI endoscopy (OGD)	From individual patient enrolment to completion and reporting of capsule endoscopy examination	The principal research objective that this study seeks to address is if robot assisted magnetically controlled capsule endoscopy may be safely and effectively used as an alternative to upper GI endoscopy (OGD) (i.e. it is non-inferior when compared to OGD) in the investigation of patients with iron deficiency anaemia.; This will be achieved through a review of OGD reports, the findings of which will be recorded. These will be directly compared to the findings at robot assisted magnetically controlled capsule endoscopy and any differences noted. Cohen's kappa coefficient will be used to assess the degree of diagnostic agreement between OGD and robot assisted magnetically controlled capsule endoscopy, with reference to the total number of lesions and specific pathology detected.
