Small intestine polypoid arteriovenous malformation: a stepwise approach to diagnosis in a paediatric case

We report a case of acute gastrointestinal haemorrhage due to a small intestine polypoid arteriovenous malformation (AVM) in a patient with a remote history of obscure gastrointestinal bleeding (OGIB) 8 years earlier. The diagnosis of a small intestine AVM was made using video capsule endoscopy (VCE) and confirmed using single-balloon push enteroscopy. The lesion was marked with submucosal tattoo to aid in subsequent surgical resection of the lesion with primary duodenoduodenostomy. Since our patient's initial bleeding episode, a variety of advanced tools have become widely available to aid in the localisation of OGIB. This case illustrates the use of a stepwise approach using new medical technology to identify and manage OGIB in children. VCE and push enteroscopy proved to be important diagnostic modalities in this paediatric case.
