An extraluminal migration of a gastrointestinal foreign body to the anterior abdominal wall: A rare case report.

Ingested foreign bodies fail to pass spontaneously through the gastrointestinal tract in about 20 % of the cases and result in complications in about 1 % of the cases. One of the complications is the migration of the foreign body to the adjacent structure. A 25-year-old female lady presented to our hospital with a 15-cm-long coilable and insulated electrical wire foreign body in her abdomen, which extended from the descending colon to the right upper quadrant abdominal wall. Intra-abdominally, the object was located in the general peritoneum without penetrating the bowel or vascular structure. It was complicated by an abdominal wall abscess without any collection in the general peritoneum. The foreign body was then successfully retracted from the abdomen through a right upper quadrant incision without any complications thereafter. The uncomplicated passage of foreign bodies through the gastrointestinal tract largely depends on the types of objects. Sharp, elongated objects are more likely to be arrested in the bowel commonly at the point of acute angulation and narrowing. The stacked foreign body may then result in different complications, including penetration and migration of the object. Migration of an insulated electrical wire to the anterior abdominal wall, which we encountered, is extremely rare and can pose a difficulty and dilemma in deciding on management options. For an externally accessible, migrated intra-abdominal foreign body that does not result in peritonitis and is confirmed to be located out of the bowel, an exploratory laparotomy could be avoided.
