Spontaneous resolution of gastric perforation caused by an ingested foreign body: a case report.

Foreign body ingestions are commonly seen and are usually uneventful. Very rarely, ingested foreign bodies will cause perforation of the gastrointestinal tract, which can lead to peritonitis, abscesses or fistulation. This is the case of a patient with vague abdominal pain after voluntary ingestion of bleach and an ink pen. The ink pen was found lodged in the gastric antral wall on esophagogastroduodenoscopy. The foreign body spontaneously migrated into the gastric lumen and was successfully removed with endoscopy.
