Liver abscess and pseudotumoral gastric lesion caused by chicken bone perforation: laparoscopic management.

The accidental ingestion of a foreign body into the gastrointestinal tract is not uncommon, but the vast majority of foreign bodies pass through the gastrointestinal tract uneventfully within a week. Less than 1% of patients with foreign body ingestion develop complications such as perforation of the gastrointestinal tract. The migration of an ingested foreign body may result in chronic inflammation, a silent clinical course, and radiological features suggestive of a neoplasm. The authors report a case of chicken bone perforation of the gastric wall that leads to hepatic abscess formation and thereafter to submucosal pseudotumor of the gastric wall treated with totally laparoscopic management. Usefulness of endoscopic ultrasonography for a correct diagnosis is also stressed.
