Abstract

Background

Laparoscopic magnetic sphincter augmentation (MSA) with the LINX device is a promising new therapy for the treatment of gastroesophageal reflux disease (GERD). Initial studies have demonstrated MSA to be safe and effective. However, no direct comparison between MSA and laparoscopic Nissen fundoplication (LNF), the gold standard surgical therapy for GERD, has been performed.

Methods

A single institution, case–control study was conducted of MSA performed from 2012 to 2013 and a cohort of LNF matched for age, gender, and hiatal hernia size.

Results

MSA and LNF were both effective treatments for reflux with 75 and 83 % of patients, respectively, reporting resolution of GERD at short-term follow-up. Dysphagia was common following both MSA and LNF, but severe dysphagia requiring endoscopic dilation was more frequent after MSA (50 vs. 0 %, p = 0.01). Need for dilation did not correlate with size of the LINX device or any other examined patient factors. A trend toward decreased adverse GI symptoms of bloating, flatulence, and diarrhea was seen after MSA compared to LNF (0 vs. 33 %). MSA had a shorter operative time (64 vs. 90 min, p < 0.01) but other peri-operative outcomes, including pain, morbidity, and re-admissions were equivalent to LNF. MSA patients were more likely to be self-referred (58 vs. 0 %, p < 0.001).

Conclusions

MSA and LNF are both effective and safe treatments for GERD; however, severe dysphagia requiring endoscopic intervention is more common with MSA. Other adverse GI side effects may be less frequent after MSA. Consideration should be paid to these distinct post-operative symptom profiles when selecting a surgical therapy for reflux disease.
