Percutaneous Interventional Radiology-Operated Endoscopy for Foreign Body Removal

Image-guided retrieval of endovascular devices such as inferior vena cava filters, guidewires, and stents is well reported, though there is a paucity of published reports on biliary, genitourinary, or gastrointestinal foreign body retrieval utilizing percutaneous endoscopy, particularly when it is performed solely by interventional radiologists. In cases of failed traditional endoscopic techniques or to evade more invasive surgical options, percutaneous endoscopy can be an adjunctive tool employed by interventional radiologists to extract foreign bodies. In this article, clinical evaluation, perioperative management, and procedural techniques for biliary, genitourinary, and gastrointestinal endoscopy for foreign body retrieval are reviewed

Percutaneous transgastrostomic interventional radiology-operated endoscopy facilitates foreign body removal using rigid endobronchial forceps

Retained foreign bodies within the stomach and proximal small bowel may be problematic in patients with prior cerebrovascular injury or head, neck and esophageal malignancy, given the increased vulnerability of this patient population to complications from aspiration and increased difficulty of esophagogastroduodenoscopy in cases of tumoral obstruction. This article presents an alternative method for foreign body retrieval through an existing gastrostomy tract, which offers the benefits of fast procedure times, reduction in radiation dose and fluoroscopy time, and allows for safer retrieval of foreign bodies by using direct visualization. This technique may be performed entirely by interventional radiologists

Bleeding diverticulum of the colon treated with CT-guided percutaneous injection of epinephrine and cyanoacrylate

Hematochezia may be a result of anatomic, vascular, inflammatory, infectious, or neoplastic diseases. Colonoscopic evaluation and therapy may be limited because of intermittent bleeding in the setting of numerous diverticula. This report describes a patient with diverticulosis who presented with hematochezia and hemodynamic instability with failed colonoscopic and arteriographic evaluations, and was treated with percutaneous transcolonic diverticular cyanoacrylate and epinephrine injection.
