Clinical and endoscopic features of aorto-duodenal fistula resulting in its definitive diagnosis: an observational study

Abstract Background Upper gastrointestinal (GI) bleeding is the most important presentation of an aorto-duodenal fistula (ADF). Early diagnosis difficult, and disease associated with high mortality. The present study aimed to examine clinical endoscopic characteristics ADF in eight patients who presented our hospital. We also sought clarify diagnostic approach towards disease. Methods examined endoscopic/computed tomography (CT) were definitively diagnosed this condition a 12-year period at Results comprised five men three women, mean age 69.8 years. was chief complaint for all patients. Out these, two shock. patients’ haemoglobin 7.09 g/dL, number blood transfusions 7.5. All had undergone intervention manage aortic pathology past. As first investigation, upper GI endoscopy 5 CT scan 3 performed. In cases where performed first, no definitive obtained, confirmed by performing endoscopy. made only one case, other scan. some cases, tip attachments, converting long endoscopes, marking clips found useful. Conclusions have episodes bleeding, cannot be investigation. addition, when suspected, attachment, endoscope, using can helpful.
