Visceral artery embolization after endoscopic injection of Enteryx for gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) can be difficult to manage medically and may require endoscopic or surgical interventions. The Enteryx procedure was designed to enhance the gastroesophageal barrier function by endoscopic injection of a copolymer into the lower esophageal sphincter. We present a rare case of a patient who was found to have migration of the copolymer into the celiac trunk and bilateral renal arteries during a work-up for persistent intermittent hematuria, which began shortly after Enteryx therapy for GERD.
