"The missing LINX" for gastroesophageal reflux disease: Operative techniques video for the Linx magnetic sphincter...

In 2012 the FDA approved a magnetic sphincter augmentation (MSA) device (LINX, Torax Medical, Inc) for placement around the lower esophageal sphincter as an alternative approach to fundoplication for gastroesophageal reflux disease (GERD). This is a relatively new procedure and there is not widespread familiarization with the standard indications and techniques of device placement. We present two operative videos to highlight the standard surgical technique and technical points needed for successful LINX placement. First will be placement in a standard indications setting of uncomplicated GERD with no hiatal hernia. Second will be placement with complicated anatomy due to alterations from prior gastric surgery and a hiatal hernia. Our experience has revealed that the LINX device can be placed safely in patients with normal or significantly altered anatomy but requires adherence to several key principles and technical points. This procedure offers a new option that is anatomically and physiologically unique compared to standard fundoplication, and that offers highly effective control of GERD with a less invasive approach.
