Magnetic sphincter augmentation for gastroesophageal reflux disease: review of clinical studies.
Use of the magnetic sphincter augmentation (MSA) device for the laparoscopic treatment of gastroesophageal reflux disease is increasing since the first clinical implant performed a decade ago. The MSA procedure is a minimally invasive and highly standardized surgical option for patients who are partially responders to proton-pump inhibitors, which have troublesome regurgitation or develop progressive symptoms despite continuous medical therapy. ⋯ The device can be easily removed if necessary, thereby preserving the option of fundoplication in the future. The majority of the removals have occurred within 2 years after implant and have been managed non-emergently, with no complications or long-term consequences. "Expanded" indications to MSA (large hiatal hernia and Barrett's esophagus) need to be tested in further comparative studies with classic fundoplication procedures.
