Transmural coil extrusion after embolization for colonic hemorrhage.

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.
