An uncommon source of upper gastrointestinal bleeding: epiphrenic esophageal diverticulum

Esophageal diverticula are rare findings that have an estimated incidence of 1 per 500 000 people per year, even though acute upper gastrointestinal bleeding is a relatively common medical emergency with an incidence of up to 150 per 100 000 people per year and a mortality rate of 7–14%. An 83-year-old man presented with hematemesis and melena. Urgent upper endoscopy revealed an esophageal diverticulum, within which was an adherent clot. Removal of the clot identified a bleeding vessel within the diverticulum; this was successfully clipped and hemostasis was achieved. To the best of our knowledge, this is the first case report of a bleeding epiphrenic esophageal diverticulum that was successfully managed endoscopically with hemostatic clips alone. While rare, our case serves as a reminder that bleeding epiphrenic esophageal diverticula can present as massive upper gastrointestinal bleeding and urgent endoscopic therapy can be life-saving.
