title: Obscure gastrointestinal bleeding due to carcinoid tumours of the small bowel: problems in diagnosis and localisation.
abstract: Patients with obscure gastrointestinal bleeding are often difficult to manage and frequently undergo extensive investigations. The diagnosis is particularly difficult when the bleeding arises from small lesions in the small bowel that is not easily accessible for direct visualisation. We report two patients with obscure gastrointestinal bleeding from carcinoid tumours of the small bowel, highlighting the problems in diagnosis and localisation.
