Diagnostic conundrum: an elusive bleeding source in patient with recurrent gastrointestinal bleeding

Abstract

Over a 6-month period, a 69-year-old woman presented with recurrent symptomatic anaemia, melaena and haematochezia. Extensive investigations were carried out, including CT of the abdomen and pelvis, oesophagogastroduodenoscopy, colonoscopy, two capsule endoscopies and two CT angiograms. The lack of active bleeding at the time of both CT angiograms meant a diagnosis was only made following retrospective examination of images by interventional radiology once fresh ampullary bleeding was identified on capsule endoscopy. The unifying diagnosis was haemosuccus pancreaticus given the combination of the left gastric artery pseudoaneurysm, fresh bleeding identified from ampulla and the patient’s history of chronic alcohol-related pancreatitis. Subsequent coil embolisation was performed to an optimal result with no recurrence of symptoms to date.
