Background
Obese patients with gastroesophageal reflux disease (GERD) refractory to medical therapy are a challenging patient population as obesity is a preoperative predictor of failure after antireflux surgery. We therefore sought to evaluate outcomes using one of two commercially available endoluminal therapies in this population.
Methods
Consecutive obese patients (body mass index (BMI) > 30) with GERD (DeMeester >14.5) undergoing either Plicator (NDO) or Stretta (Curon) were identified in our single-institution prospective database. Outcomes assessed were: (1) failure rate (absolutely no symptomatic improvement after procedure and/or need for subsequent antireflux surgery), (2) postoperative vs. preoperative symptom (heartburn, chest pain, regurgitation, dysphagia, cough, hoarseness, and asthma) scores, and (3) proton-pump inhibitor (PPI) medication use.
Results
Twenty-two patients each underwent an endoluminal therapy (ten Plicator patients and 12 Stretta patients) with mean follow-up of 1.5 years. There were no treatment-associated complications. Mean BMI was not different between Plicator and Stretta groups (39.6 vs. 38.6, respectively, p = 0.33). The failure rate for the entire cohort was 28% (10% Plicator vs. 42% Stretta, p = 0.11). The proportion of patients reporting moderate/severe symptoms postop was significantly less than preop: chest pain 9% vs. 13% (p = 0.04), cough 22% vs. 36% preop (p = 0.025), voice changes 9% vs. 36% preop (p = 0.012), and dysphagia 9% vs. 32% preop (p = 0.04). The proportion of patients on PPI medications postop was also less than preop (45% vs. 81%, p = 0.1)
Conclusion
Endoluminal treatment can provide a safe means of improving GERD symptoms for some obese patients, though many will continue to require medication therapy also. Further work aimed at understanding optimal candidates for endoluminal therapy in this patient population is warranted.
