Material and Methods
We retrospectively reviewed prospectively collected data on consecutive patients who underwent laparoscopic implantation of a magnetic sphincter at Swedish Medical Center from September 2012 to December 2013. The Institutional Review Board of Swedish Medical Center approved this study and waived the need to implant the devices under a research protocol. Magnetic sphincters were placed as part of clinical care, and patient consent was provided for implantation; however, individual patient
Results
Of the 34 patients who underwent MSA, 24 completed the 6-month follow-up. For comparison, 32 patients underwent LNF. The baseline demographic and GERD characteristics of both groups were similar, except MSA patients were older, and LNF patients had a higher body mass index (Table 1).
The operative time for MSA was 73 minutes compared with 118 minutes for LNF (p = 0.001). There were no operative deaths. In the MSA group, there were no major morbidities. Minor morbidities included symptomatic
Comment
The main finding in this study is that patients with GERD, with or without a hiatal hernia smaller than 3 cm, undergoing MSA with the LINX device (Torax Medical Inc, Shoreview, MN) have equivalent outcomes compared with patients with similar characteristics undergoing LNF. MSA alleviates typical and atypical symptoms of GERD, improves quality of life, and normalizes distal esophageal acid exposure. Our MSA results are similar compared with previous published studies and add to the growing
