Summary: | Gastroesophageal reflux disease (GERD) and aspiration of enteric contents are associated with worse outcomes after lung transplantation. The purpose of this study was to elucidate populations of patients who benefit the most from fundoplication after lung transplantation.
Lung transplantations from 2001 to 2019 (n = 971) were retrospectively reviewed and stratified by fundoplication before (n = 128) or after (n = 24) chronic lung allograft dysfunction (CLAD) development vs patients who did not undergo fundoplication. Patients with a fundoplication before CLAD were propensity matched to patients without a fundoplication. The primary outcome of interest was posttransplant survival. Time-to-event rates were calculated using a multivariable Cox proportional hazards model and Kaplan-Meier functions.
Fundoplication before CLAD improved posttransplant survival before and after propensity matching, and it remained a significant predictor after adjusting for baseline characteristics (hazard ratio [HR],0.57; 95 % confidence interval [CI], 0.4 to 0.8; P = .001). Transplant recipients with a restrictive disorder (HR, 0.46; 95 % CI, 0.3 to 0.73; P = .001), age younger than 65 years (HR, 0.48; 95 % CI, 0.32 to 0.71; P < ;0.001), and with both single (HR, 0.47; 95 % CI, 0.28 to 0.79; P = .005) and double (HR, 0.55; 95 % CI, 0.32 to 0.93; P = .027) lung transplants had a significant decrease in mortality after fundoplication. The effect was present after excluding early deaths and CLAD diagnoses. Gastroesophageal reflux disease diagnosed by pH, impedance, or esophagogastroduodenoscopy was not associated with worse outcomes. Among patients with CLAD, a fundoplication was an independent predictor of post-CLAD survival (HR, 0.27; 95 % CI; 0.12 to 0.61; P = .002).
Fundoplication before or after CLAD development is an independent predictor of survival. Younger patients with restrictive disease, independent of the type of transplant, have a survival benefit. Gastroesophageal reflux disease diagnosed by conventional methods was not associated with worse survival.
