Fishbone foreign body ingestion in duodenal papilla: a cause of abdominal pain resembling gastric ulcer.

BACKGROUND

Foreign body ingestion is a common clinical problem. The upper esophagus is the most common site of foreign body, accounting for more than 75% of all cases, but cases with a foreign body in the duodenal papilla or common bile duct are rarely reported.

CASE PRESENTATION: Herein, we report a rare case that a patient's abdominal pain resembling gastric ulcer was caused by a 3 cm long fishbone inserted into the duodenal papilla.

CONCLUSION

Fishbone inserted into the duodenal papilla can cause an abdominal pain resembling gastric ulcer. Endoscopy is useful for the diagnosis and treatment of fishbone ingestion in clinical.
