Gastroesophageal reflux disease (GERD) is a common chronic upper gastrointestinal disease with both objective and subjective components. It is defined as a reflux of gastric contents into the esophagus, which causes symptoms such as heartburn, regurgitation, and dysphagia. Severity of the disease is dependent on both severity of the symptoms and severity of the mucosal damage done by the reflux. While many cases of GERD can be managed with oral medication, persistent and refractory cases require surgical intervention. The purpose of this literature review is to compare the efficacy of GERD’s gold standard surgical technique, the Nissen fundoplication, with a new surgical technique, magnetic sphincter augmentation. Studies were included if they analyzed either procedure against itself or directly compared the two procedures. No specific requirements were set, but special attention was paid to the patient inclusion criteria to assess for common themes between the studies. The data available at this time indicates that in patients who qualify for both procedures, magnetic sphincter augmentation and Nissen fundoplication produce similar levels of efficacy and patient satisfaction.
