An extremely dangerous case of acute massive upper gastrointestinal bleeding: a case report

Upper gastrointestinal (GI) bleeding is a severe acute disease of gastroenterology department. Fish bone is the most common food-related foreign body. However, fish bone piercing the esophagus, causing the mediastinal abscess that corroded the left subclavian artery, resulting delayed but high-risk massive upper gastrointestinal bleeding is very rare.

We report a 54-year-old man who was diagnosed with delayed but high-risk massive upper GI bleeding that was the result of a fish bone piercing the esophagus, causing a mediastinal abscess that corroded the left subclavian artery. He was saved effectively by early and timely multidisciplinary collaboration.

A fish bone-caused mediastinal abscess that corrodes the left subclavian artery and induces delayed but high-risk massive upper GI bleeding is very rare. In addition to routine consideration of upper GI bleeding, medical history, endoscopy and CT are helpful for achieving a diagnosis. Importantly, early and timely multidisciplinary collaboration can effectively save critically ill patients.
