LINX Reflux Management System or Fundoplication Clinical Study in Patients With Hiatal Hernia >3 cm

The cohort registry is both retrospective and prospective, multicenter surveillance of subjects who underwent a prior hiatal hernia repair and Magnetic Sphincter Augmentation or fundoplication construction more than 2 years prior to initial study visit.

The cohort registry is both retrospective and prospective, multicenter surveillance of subjects who underwent a prior hiatal hernia repair and anti-reflux surgery with either Magnetic Sphincter Augmentation (MSA) using LINX placement or fundoplication construction more than 2 years prior to initial study visit. Subjects will be enrolled by invitation only by participating investigators. Enrollment will consist of 300 LINX MSA patients and 150 fundoplication patients with a total of 450 from 4 sites within the United States. Data will be collected for up to 6 years.The primary objective of this study is to determine the long-term incidence of hiatal hernia recurrence in patients who undergo hiatal hernia repair of a large (\>3 cm) hernia with LINX® device placement, and to compare this with hiatal hernia recurrence rates in patients who underwent hiatal hernia repair with fundoplication.
