AbstractThe addition of posterior cruroplasty to magnetic sphincter augmentation (MSA-PC) has been shown to be effective in treating gastroesophageal reflux disease (GERD). This study evaluates the predictors of persistent postoperative dysphagia, one of the major complaints after MSA-PC. From August 2015 to February 2018 the medical records of 118 patients (male=59, female=59) receiving MSA-PC for GERD were reviewed. Postoperative dysphagia was present in 80 patients (67.8%), with 20 (16.9%) requiring dilation for persistent dysphagia. Three patients (2.5%) had the magnetic sphincter augmentation device removed for persistent dysphagia, one was converted to a Nissen fundoplication. The median number of dilations was 1, mean time from surgery to dilation was 5.6 months, and 15/20 (75%) had symptom resolution after 1 to 2 dilations. Dilated patients were more likely than nondilated patients to have atypical GERD symptoms preoperatively (70% vs. 44.7%, P=0.042). After dilation, 93.3% of patients reported a good quality of life.
