title: Fever of unknown origin after Angelchik antireflux prosthesis implantation.
abstract: The Angelchik device is a silicone collar placed at the gastroesophageal junction for preventing reflux. Many complications associated with the use of this device have been reported, including disruption, migration, and erosion into the gastrointestinal tract. We report another complication of the device, that of abscess formation presenting as fever of unknown origin. This complication emphasizes the need for careful investigation of any implanted foreign body in the evaluation of a patient who has fever of unknown origin.
