Abstract
Foreign body ingestion is not uncommon, but in most patients the object passes without sequelae. In very few patients, the ingested foreign objects may perforate the gastrointestinal tract, causing potentially life-threatening complications. Pointed ingested objects such as toothpicks are the most common. Vascular perforation due to toothpick ingestion has rarely been reported. We present a patient with lower gastrointestinal bleeding secondary to simultaneous perforation of the sigmoid colon and the right iliac limb of an aortobiiliac endograft by an ingested toothpick. This arterioenteric fistula was treated in two stages. First as a bridging operation, a stent graft was inserted into the ipsilateral limb of the previous aortoiliac endograft to control the bleeding. Second, the aortoiliac endograft was removed, the aorta was oversewn, and an extra-anatomic axillobifemoral bypass restored the flow to the lower limbs. The colon perforation was treated with a proximal temporary loop colostomy. To our knowledge, this the first case of aortoiliac endograft-enteric fistula after endovascular abdominal aortic aneurysm repair caused by this extraordinary mechanism.
