Aortogastric Fistula Caused by a Foreign Body in a Hiatal Hernia.

Foreign body ingestion is more common in children than in adults, and sharp foreign body ingestion is extremely rare. We report a 93-year-old woman who was unaware of foreign body ingestion and who presented with sudden hematemesis and circulatory collapse. Computed tomography showed a hiatus hernia and part of the stomach herniating in the posterior mediastinum. Additionally, a needle-shaped object was seen penetrating the aorta through the herniated gastric wall. Therefore, immediate endovascular repair of the aorta was performed. Subsequent endoscopy identified a bamboo stick. Therefore, emergent laparotomy and gastrotomy were performed to retrieve the stick, followed by repair of the hernia. The postoperative recovery was uneventful. Such cases are associated with high morbidity, mandating long-term follow-up.
