Prostheses, Gastroesophageal, Antireflux
Definition : Prostheses designed to be introduced into the esophagogastric sphincter to reduce a sliding hiatal hernia, preventing the reflux of gastric contents into the esophagus. These prostheses typically consist of a toroidal, C-shaped elastomer ring filled with a silicone gel and a polyester tie to secure the ring around the esophagogastric junction. Antireflux prostheses are intended for surgical implantation under the diaphragm to hold the lower esophagus in place as an alternative to traditional surgical fixation of the stomach (i.e., gastropexy) or fundoplication.
