Résumé
Magnetic sphincter augmentation (MSA) is a promising surgical treatment for patients with GERD. The aim of this study was to evaluate the outcomes of MSA in a large cohort of patients with GERD and to determine the factors predicting a favorable outcome. This was a retrospective review of prospectively collected data of 553 patients who underwent MSA at our institution in a 5-year period. Preoperative clinical, endoscopic, manometric, and pH data were used in a univariate analysis. This was followed by a regression multivariable analysis to determine the factors predicting a favorable outcome. Favorable outcome was defined as freedom from proton pump inhibitors and ≥50% improvement in Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) total score. At a mean (SD) follow-up of 10.3 (10.6) months after MSA, 92.7% of the patients were free of proton pump inhibitor use and 84% reported at least 50% improvement in their GERD-HRQL total score. The GERD-HRQL total score was improved from a mean (SD) baseline value of 33.8 (18.7) to 7.2 (9.0) (p < 0.001) and 76.1% of the patients had normalization of their esophageal acid exposure. Independent predictors of a favorable outcome after MSA included age younger than 45 years (odds ratio [OR] 4.2; 95% CI, 1.1 to 15.2; p = 0.0305), male sex (OR 2.5; 95% CI, 1.1 to 5.7; p = 0.0301), GERD-HRQL total score >15 (OR 7.5; 95% CI, 3.3 to 16.8; p < 0.0001), and abnormal DeMeester score (OR, 2.6; 95% CI, 1.1 to 5.7; p = 0.0225). In this largest single-institution series, we demonstrate that MSA implantation is associated with very good clinical and objective outcomes. Age younger than 45 years, male sex, GERD-HRQL total score >15, and abnormal DeMeester score are the 4 preoperative factors predicting a favorable outcome and can be used in patient counseling and MSA use.

BACKGROUND
Magnetic sphincter augmentation (MSA) is a promising surgical treatment for patients with GERD. The aim of this study was to evaluate the outcomes of MSA in a large cohort of patients with GERD and to determine the factors predicting a favorable outcome.
METHODS
This was a retrospective review of prospectively collected data of 553 patients who underwent MSA at our institution in a 5-year period. Preoperative clinical, endoscopic, manometric, and pH data were used in a univariate analysis. This was followed by a regression multivariable analysis to determine the factors predicting a favorable outcome. Favorable outcome was defined as freedom from proton pump inhibitors and ≥50% improvement in Gastroesophageal Reflux Disease-Health-Related Quality of Life (GERD-HRQL) total score.
RESULTS
At a mean (SD) follow-up of 10.3 (10.6) months after MSA, 92.7% of the patients were free of proton pump inhibitor use and 84% reported at least 50% improvement in their GERD-HRQL total score. The GERD-HRQL total score was improved from a mean (SD) baseline value of 33.8 (18.7) to 7.2 (9.0) (p < 0.001) and 76.1% of the patients had normalization of their esophageal acid exposure. Independent predictors of a favorable outcome after MSA included age younger than 45 years (odds ratio [OR] 4.2; 95% CI, 1.1 to 15.2; p = 0.0305), male sex (OR 2.5; 95% CI, 1.1 to 5.7; p = 0.0301), GERD-HRQL total score >15 (OR 7.5; 95% CI, 3.3 to 16.8; p < 0.0001), and abnormal DeMeester score (OR, 2.6; 95% CI, 1.1 to 5.7; p = 0.0225).
CONCLUSIONS
In this largest single-institution series, we demonstrate that MSA implantation is associated with very good clinical and objective outcomes. Age younger than 45 years, male sex, GERD-HRQL total score >15, and abnormal DeMeester score are the 4 preoperative factors predicting a favorable outcome and can be used in patient counseling and MSA use.
