Does anti-reflux mucosal ablation (ARMA) improve refractory GERD in patients after Roux-en-Y gastric bypass?
Anti-reflux mucosal ablation may be a viable treatment option for refractory GERD following Roux-en-Y gastric bypass.
Roux-en-Y gastric bypass (RYGB) is the gold standard bariatric surgical intervention in obese patients with pre-operative gastroesophageal reflux disease (GERD) 1. Several hypotheses have been proposed to explain GERD recurrence postoperatively, including retained acid-secreting parietal cells in the pouch 2, dysmotility of the Roux limb, and herniation of the gastric pouch through the hiatus. We report the successful treatment of refractory GERD following RYGB using anti-reflux mucosal ablation (ARMA) (Fig. 1).
