Examination of the upper gastrointestinal tract (oesophagus, stomach and duodenum) involves passing a flexible tubular endoscope through the mouth into the stomach. It is commonly performed to identify the cause of abdominal pain, indigestion, diarrhoea and anaemia. As it is an invasive and uncomfortable test, it is usually performed under general anaesthetic in children. However, children and their parents worry about the nature of the procedure which does incur a small risk of both the anaesthetic and the endoscopy.
A capsule endoscope is a large pill-sized device containing a battery powered camera which can be swallowed. It was first devised to examine the small bowel (which begins with the duodenum and ends in the colon or large bowel) which is difficult to reach with conventional endoscopes and has been used in children aged over eight years since at least 2005. It is extremely well tolerated. However, it does not provide a comprehensive view of the whole surface area of the stomach which has a convoluted shape, large volume and is collapsed in the fasted state.
Recent research in adults shows that a capsule can be steered around a water-filled stomach using two joysticks to control the polarity and distance of an external robot magnet from the patient. This is much better tolerated and appears to be almost as good a diagnostic tool as conventional endoscopy. It has yet to be studied in children. We intend to compare patient acceptability of capsule endoscopy and gastroscopy and see if it is cost effective.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Abdominal pain requiring investigation by OGD
* Participant must be willing to undergo both procedures (i.e. ingestion of the capsule and standard of care Oesophago-gastro duodenoscopy (OGD)
* Age 11-16 years inclusive
Exclusion Criteria:
* Dysphagia
* Inability to swallow capsule
* Small bowel stricture
* Disease associated with small bowel stricturing (Crohn's disease, previous small bowel surgery, previous abdominal or pelvic radiation therapy, long term daily (\>6 months) non-steroidal anti-inflammatory drug consumption)
* Pacemaker or other implantable electrical cardiac or neurological device

* Participants who are pregnant or who have implantable electronic devices cannot take part in the study. Depending on their age and pubertal status the female patients will be offered a pregnancy test prior to any examinations. Capsule endoscopy is not advised during pregnancy.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
