Is magnetic sphincter augmentation indicated in patients with laryngopharyngeal reflux?

Up to 30% of patients with gastroesophageal reflux disease (GERD) suffer from laryngopharyngeal reflux (LPR) with symptoms, as chronic cough, laryngitis, or asthma. Besides life-style modifications and medical acid suppression, laparoscopic fundoplication is an established treatment option. Treatment-related side effects after laparoscopic fundoplication have to be weighted against LPR symptom control in 30-85% of patients after surgery. Magnetic sphincter augmentation (MSA) is described as an effective alternative to fundoplication for surgical treatment of GERD. However, evidence on the efficacy of MSA in patients with LPR is very limited. Preliminary data on the results of MSA treating LPR symptoms in patients with acid and weakly acid reflux are promising; showing comparable results to laparoscopic fundoplication by providing the potential of decrease side effects.
