The Teaching Point

Metallic embolization microcoils used for transcatheter treatment of gastrointestinal bleeding can extrude through the colonic wall, without adverse clinical sequelae. Recognition of this unusual phenomenon may minimize endoscopic and clinical confusion, and help physicians better identity the frequency with which this event occurs.

Transmural Coil Extrusion After Embolization for Colonic Hemorrhage

Abstract
Transcatheter embolization is increasingly accepted as a safe and effective therapy for acute lower gastrointestinal hemorrhage, but the fate of the coils used for treatment is not entirely known. We report a patient with massive descending colonic bleeding, successfully treated with microcoil occlusion, in whom partially extruded coils were later visualized colonoscopically, but initially misidentified as ingested jewelry. The incidence of this endoscopically enigmatic (but in this case clinically inconsequential) finding is unknown.
