A 55-year-old male swallowed fish bone accidentally and subsequently developed retrosternal pain. He underwent chest computed tomography at his local hospital on October 23, 2023, showing esophageal foreign body with suspected esophageal rupture. One day later, he underwent endoscopy at our department, showing a fish bone penetrated into the esophageal wall. After consultation with cardiothoracic surgeons, endoscopy-guided removal of this foreign body was performed under anesthesia. An esophageal ulcer with a length of 2cm was left with overflowing air bubbles, and was closed by three metal clips. Two days later, retrosternal pain disappeared. A tube was intubated to duodenal distal segment under endoscopy, via which enteral nutritional suspension was given. Then, he was discharged.
