Laparoscopic placement of the LINX Magnetic Sphincter Augmentation (MSA) device, either with or without formal hiatal hernia repair, is an effective alternative to fundoplication in appropriate patients. Formal hiatal hernia repair during MSA implantation provides better control of reflux with reduced dysphagia and postoperative hernia risk compared to no hiatal hernia repair. Systematic crural repair should be performed during MSA implantation regardless of the presence or size of hiatal hernia.
Laparoscopic placement of the LINX Magnetic Sphincter Augmentation (MSA) device has become an accepted alternative to fundoplication in appropriate patients. Initial studies of MSA targeted to patients with 'early' disease allowed for the most minimal dissection of the esophagus to place the device, without hiatal dissection or repair (NoHHR), in patients with no or minimal hernia findings at surgery. Subsequent studies have compared systematic formal hiatal dissection and repair (Formal HHR) with the original minimal dissection technique. Review of published literature on MSA includes discussion on treatment of hiatal hernia at the time of implantation, accompanying the review of the physiology of the crural diaphragm. Formal hiatal hernia repair at the time of MSA implantation results in better control of reflux with less dysphagia and risk of postoperative hernia than NoHHR, regardless of the presence or size of hiatal hernia. Systematic crural repair should accompany any MSA implantation regardless of the presence or size of hiatal hernia.
