A recent review of the MBSAQIP (Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program) by authors Clapp, et al.n observed that magnetic sphincter augmentation (MSA) is being performed prophylactically for gastroesophageal reflux disease  (GERD) at the time of primary bariatric surgery (18 in laparoscopic sleeve gastrectomy  [LSG] and 6 in Roux-en-Y gastric bypass [RYGB] patients).

The American Foregut Society Bariatric Committee has reviewed this paper at length and the observation is notable.  The Society agrees with the comments that this is off label use and needs oversight.  More importantly, the committee has several concerns about this combination from clinical and physiologic perspective; especially in the context of this limited study design.
