Abstract
Magnetic sphincter-augmentation (MSA) has been proven effective in the treatment of GERD. No consensus exists on whether crural closure should be performed. Our aim was to assess the impact of cruroplasty on reflux-control and quality of life. MSA-Patients treated between 03/2012-03/2017 were classified into those without hiatal hernia ("NHH"), those post-MSA (NHR) and those post-MSA/hiatal repair (HR). GERD-symptoms, PPI-intake, GERD-Health-related-Quality-of-Life (GERD-HRQL) and Alimentary Satisfaction were assessed. Sixty-eight patients underwent MSA, 26 patients had additional crural closure. PH-monitoring was negative in 80% of HR, 73% of NHR and 89% of NHH-patients. GERD-HRQL-total scores decreased significantly in all groups (p < 0.001). Alimentary satisfaction was 8/10 in HR/NHH and 10/10 in NHR-patients. Satisfaction with heartburn relief was high (HR: 96%, NR: 95%, NHH: 94%) as was the elimination of PPI-intake (HR/NHH: 87%, NR: 86%). Heartburn and regurgitations were eliminated in 100% of HR, 88% and 94% of NHR and 87% and 91% of NHH-patients. Endoscopic dilatation or device explantation was performed in 3% each. MSA leads to significant symptom relief, increased quality of life and alimentary satisfaction with low perioperative morbidity. Cruroplasty tends to result in better reflux control and symptom relief than exclusive MSA without increasing dysphagia rates.
