What investigations are recommended for a patient with recurrent episodes of haematemesis?

For a patient experiencing recurrent episodes of haematemesis, a non-urgent, direct access upper gastrointestinal endoscopy should be considered NICE NG12. If the patient re-bleeds after initial treatment for upper gastrointestinal bleeding, a repeat endoscopy should be offered with a view to further endoscopic treatment or emergency surgery NICE CG141. A repeat endoscopy should also be considered for all patients at high risk of re-bleeding, particularly if there is doubt about adequate haemostasis at the first endoscopy NICE CG141.
