Abstract
BackgroundAnti-reflux mucosectomy is a novel endoscopic treatment for gastroesophageal reflux disease that serves as an intermediate therapy between medical and surgical intervention. We aimed to evaluate outcomes and identify predictors of treatment failure in patients requiring anti-reflux mucosectomy. MethodsA prospective quality database was retrospectively reviewed. Upper endoscopy, pH testing, and functional luminal impedance planimetry were obtained at preop and 1 year post-operation. Quality of life outcomes were assessed by Gastroesophageal Reflux Disease–Health Related Quality of Life, Reflux Symptom Index, and dysphagia scores preoperatively and up to 5 years postoperatively. ResultsFifty-eight patients requiring anti-reflux mucosectomy were analyzed between 2016 and 2023. Preop Gastroesophageal Reflux Disease–Health Related Quality of Life mean scores improved at all time points 3 weeks to 2 years postoperatively (all P < .05). Preop mean Reflux Symptom Index scores also significantly improved at 6-month, 1-year, and 2-year timepoints (all P < .05). Dysphagia at 3 weeks was higher than preop scores (1.2 vs 2.1, P < .01) but returned to baseline. Upon follow-up, 43 patients (74.1%) had symptom improvement off proton pump inhibitors, 29 of whom reported complete symptom resolution. Out of 58 patients, 31 (53.4%) failed treatment due to DeMeester score (n = 22), erosive esophagitis (n = 2), Gastroesophageal Reflux Disease–Health Related Quality of Life ≥13 (n = 4), or <70% symptom resolution in the absence of pH or survey data (n = 3). Current smoking status was predictive of treatment failure (odds ratio 3.52, P < .031). Body mass index, DeMeester score, acid exposure time, and hiatal hernia ≤2 cm were not associated with treatment failure. ConclusionAnti-reflux mucosectomy is associated with significant improvement in quality of life; however, symptom resolution may not correlate with objective reflux control. Smoking is a predictor of treatment failure and should be considered in patient selection.
