Short- and long-term antireflux and asthma medication use in children after nissen fundoplication.

PURPOSE We sought to determine antireflux and asthma medication use after Nissen fundoplication (NF). METHODS We performed a retrospective study using hospital discharge and pharmacy data from 1996 through 2005. A total of 342 pediatric patients had ≥1 NF; 336 of those had complete medication data. Use of antireflux medications and asthma medications were reviewed before and after NF. RESULTS Short-term (one year after NF) use of antireflux medications decreased (odds ratio [OR] = 0.35; 95% confidence interval [CI], 0.26-0.45). During the entire study period, the decrease in antireflux medication use after NF remained in place (233 to 197 patients; OR = 0.63; 95% CI, 0.47-0.84). Use of antireflux medications decreased in neurologically healthy patients (n = 186) after NF but remained the same in neurologically impaired patients. Short-term use of inhaled and systemic asthma medications did not change (OR = 1.16 [95% CI, 0.89-1.51] and 0.90 [95% CI, 0.69-1.18]), respectively. During the entire study period, inhaled and systemic asthma medication use increased after NF (OR = 2.11 [95% CI, 1.63-2.74] and 1.85 [95% CI, 1.43-2.41]), respectively. Inhaled and systemic asthma medication use increased in both neurologically healthy and impaired children. In older children (age >5 years), short-term use of inhaled and systemic asthma medications decreased after NF (OR = 0.39 [95% CI, 0.25-0.60] and 0.31 [95% CI, 0.19-0.53]), respectively. However, during the entire study period, inhaled and systemic asthma medication use in older children remained the same. CONCLUSION NF decreased antireflux medication use in the short and long term, particularly in neurologically healthy children. Inhaled and systemic asthma medication use increased after NF in neurologically healthy and impaired children. NF provided a short-term decrease in inhaled and systemic asthma medication use in older children but showed no change in the long term.
