Hepatic migration of metallic wire from gastrointestinal tract: a rare case report

The translocation of gastrointestinal (GI) foreign bodies to hepatic tissue is exceptionally rare, occurring in less than 1% of foreign body ingestion cases. Most ingested objects either remain within the GI tract or are naturally eliminated.

We present a 57-year-old man with 24-hour acute upper abdominal pain. Despite denying intentional foreign object ingestion, computed tomography (CT) revealed a linear metallic structure (3.5 cm) in the second hepatic segment. Laboratory analysis showed mild leukocytosis and elevated interleukin-6 levels. The patient underwent successful laparoscopic extraction of a 1.5 cm metallic wire with no complications and was discharged on postoperative day 7.

Hepatic foreign body migration mechanisms include direct gastroduodenal wall penetration, portal circulation migration, or hepatoduodenal ligament translocation. CT imaging is crucial for detection and localization, though metallic artifacts can overestimate size. Laparoscopic surgery is preferred for managing hepatic foreign bodies due to reduced trauma, shorter hospital stays, and faster recovery compared to open surgery.

This case highlights the rare but possible migration of grill brush bristles to the liver parenchyma, expanding the range of potential injuries associated with such incidents. As a result, early detection and prompt intervention are crucial, with minimally invasive approaches being particularly advantageous in managing these complex cases.
