Pharmacobezoar in a patient on an oral phosphate binder

摘要

Pharmacobezoars are a rare cause of intestinal obstruction.1 They are usually seen in the setting of altered mo-tility or anatomy of the GI tract, and certain medications including aluminum hydroxide, sucralfate, cholesty-ramine, nifedipine, and psyllium have been implicated in causing bezoars.2 They are difficult to diagnose reliably and usually require endoscopic or surgical management.3 Lanthanum carbonate (Fosrenol) is a chew-able oral phosphate binder used in patients with chronic kidney disease that has previously not been reported as a cause of a pharmacobezoar.
