A fatal aorto-oesophageal fistula due to a mutton bone: A case report.

introduction and importance of the caseAorto-oesophageal fistula (AEF) following foreign body ingestion is rare and conservative management is always fatal. The delayed presentation further confounds poor outcomes. PRESENTATION OF CASE: A 46-year-old South-Asian woman presented with pain and difficulty in swallowing following ingestion of a mutton-containing meal. The patient refused urgent upper GI endoscopy and was initially managed conservatively on the basis of the resolution of symptoms and hemodynamic stability and was discharged home. On review a week later, the patient did not consent to a UGIE. She presented the next day with a severe upper GI bleed. Due to profuse haemorrhage, a bleeding point could not be identified, and she suffered a cardiac arrest. Attempts at resuscitation were unsuccessful. The autopsy revealed an AEF caused by a sharp mutton bone lodged in the lower oesophagus. CLINICAL DISCUSSION: High-risk food bolus impactions such as the ones caused by sharp objects need urgent endoscopy to confirm the position and extraction if safe. AEF occurs with time and could result in massive haemorrhage and mediastinitis. Endoscopic stenting, thoracoscopic surgery, and open repair are methods of emergent and definite management that still carry significant mortality.

conclusionManagement of AEF requires early diagnosis with a high index of suspicion, endoscopic and CT-based angiography studies, and surgical interventions tailored to patients based on the available expertise. High-risk patients should be similarly educated on the probable complications and the symptomatology.
