Outcomes of surgical management of severe GERD in patients with cystic fibrosis

Abstract

Background Patients with cystic fibrosis (CF) are at high risk for gastroesophageal reflux disease (GERD) and medical management of GERD improves pulmonary symptoms. Some patients with worsening CF and GERD symptoms undergo Nissen fundoplication, but the extent to which surgical management of GERD improves respiratory symptoms is not well studied. The purpose of this retrospective study was to evaluate the safety and efficacy of Nissen fundoplication in 48 patients with CF and uncontrolled GERD. Results Patients exhibited significantly fewer pulmonary exacerbations, increased weight gain and slower decline in % predicted FEV1 at 2 years after the surgery, compared to 2 years before surgery. Mean change in % predicted FEV1 in 2 years before surgery was -13.57% and mean change in % predicted FEV1 in 2 years after the surgery was +1.5% and difference was significant P = 0.001. Better pulmonary and nutritional outcomes were noted among patients with milder lung disease compared to those with severe lung disease, and among patients who received gastrostomy tube feedings for ≥6 months compared to those with no G-tube or tube feedings for <6 months. There was no mortality associated with surgery. Conclusion In CF patients with worsening lung disease and uncontrolled GERD, Nissen fundoplication not only slows the decline in lung function but leads to significant improvement in weight, and decrease in CF exacerbations. Patients with milder disease and patients receiving G-tube feedings for ≥6 months after surgery benefited the most. Pediatr Pulmonol. 2013; 48:556-562. © 2012 Wiley Periodicals, Inc.
