Three-year clinical experience with magnetic sphincter augmentation and laparoscopic fundoplication

Area of Science:

• Gastroenterology
• Surgical Innovation
• Clinical Outcomes Research

Background:

• Gastroesophageal reflux disease (GERD) management often requires surgical intervention.
• Magnetic sphincter augmentation (MSA) and laparoscopic fundoplication (LF) are surgical options for GERD.
• Long-term effectiveness data comparing MSA and LF are crucial for clinical decision-making.

Purpose of the Study:

• To evaluate the 3-year clinical outcomes of Magnetic Sphincter Augmentation (MSA) compared to Laparoscopic Fundoplication (LF) in patients with GERD.
• To assess patient satisfaction, symptom improvement, medication use, and complication rates for both procedures over a 3-year period.

Main Methods:

• A prospective, multi-center, observational registry study (ClinicalTrials.gov identifier: NCT01624506) followed 631 patients (465 MSA, 166 LF) for 3 years.
• Data collected included baseline characteristics, reflux symptoms (GERD-HRQL), medication use, satisfaction, and complications.
• Post-surgical evaluations were conducted at yearly intervals.

Main Results:

• Both MSA and LF significantly improved GERD-HRQL scores and patient satisfaction by year 3.
• Most patients in both groups could belch as needed; MSA showed a higher ability to vomit as needed (91.2% vs. 68.0%).
• Proton pump inhibitor (PPI) usage decreased significantly post-surgery for both groups, with low complication rates (≤2%) for both MSA and LF.

Conclusions:

• This 3-year registry study supports the effectiveness and safety of both MSA and LF for GERD management.
• Clinical outcomes for MSA and LF were favorable, even in the LF group with more severe GERD.
• MSA offers comparable effectiveness to LF with potential advantages in physiological function and procedure efficiency.
