Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Study participants will swallow a capsule endoscope specifically designed to view the oesophagus and upper gastrointestinal tract. Images are transmitted wirelessly to a data recorder worn by the patient. The procedure is expected to take 2 hours. The capsule passes naturally through the bowel and is usually excreted in a bowel motion after 24 to 48 hours.

All patients will have a gastroscopy which is current standard treatment. Gastroscopy takes 15 minutes to perform. This will occur at least 2 hours after capsule ingestion.

Outcomes
Primary outcome [1] 240447 0
The success of capsule endoscopy in diagnosing (or excluding) causes of upper gastrointestinal bleeding.

Images obtained by the capsule endoscopy will be interpreted by two gastroenterologist blinded to the results of the gastroscopy. Consensus agreement will be made if there are major discrepancies between the two reports. The results of capsule endoscopy will be directly compared to the results and diagnosis obtained during the gastroscopy. A standardise reporting sheet will be used for all procedures.
Timepoint [1] 240447 0
24 hours after intervention
Primary outcome [2] 240448 0
Correlation of findings seen on capsule endoscopy compared to gastroscopy.

This will be assessed using reports optained after visual examination of the images taken by both methods.
Timepoint [2] 240448 0
24 hours after intervention
Secondary outcome [1] 244958 0
Compare the patient tolerability and satisfaction between the procedures.

This will be assed by using a patient questionnaire and use of a visual analogue scale.
Timepoint [1] 244958 0
48 hours after intervention
Secondary outcome [2] 244959 0
Safety of upper gastrointestinal capsule endoscopy in the setting of acute gastrointestinal haemorrhage.

Assessment will include adverse events related to adminstration of the capsule. The main adverse event expected is capsule retention within the bowel.

Adverse events will be assessed by direct contact witht he patient at day 14. Where it is not clear that the capsule has passed, an abdominal xray will be performed.
Timepoint [2] 244959 0
14 days after intervention

Summary
Brief summary
Capsule endoscopy has the potential to be used as a fast and minimally invasive tool for the triage of patients presenting to hospital with bleeding from the upper gastrointestinal tract.

This study aims to determine the utility of capsule endoscopy in this setting by comparing its success in finding a diagnosis for the bleeding when compared to findings made at gastroscopy.
