- BACKGROUND AND OBJECTIVE: Aspiration pneumonia is a common and serious complication to gastroesophageal reflux disease (GERD) among neurologically impaired children. Medication of GERD does not effectively prevent aspiration pneumonia, and whether antireflux surgery with fundoplication is better in this respect is uncertain. The objective was to determine whether fundoplication prevents aspiration pneumonia among children with neurological impairment and GERD.METHODS: This was a population-based cohort study from Denmark, Finland, Norway and Sweden, consisting of neurologically impaired children with GERD who underwent fundoplication. The risk of aspiration pneumonia before fundoplication (preoperative person-time) was compared with the risk after surgery (postoperative person-time). Multivariable Cox regression provided hazard ratios (HRs) with 95% confidence intervals (CIs). Except for confounding adjusted for by means of the "crossover like" design, the HRs were adjusted for age, sex, year of entry and respiratory diseases.RESULTS: Among 578 patients (median age 3.5 years), the preoperative person-time was 956 years and the postoperative person-time was 3324 years. Fundoplication was associated with 56% decreased overall HR of aspiration pneumonia (HR 0.44, 95% CI 0.27-0.72), and the HRs decreased over time after surgery. The risk of other types of pneumonia than aspiration pneumonia was not clearly decreased after fundoplication (HR 0.79, 95% CI 0.59-1.08). The 30-day mortality rate was 0.7% and the complication rate was 3.6%.CONCLUSIONS: Antireflux surgery decreases, but does not eliminate, the risk of aspiration pneumonia among neurologically impaired children with GERD. Fundoplication may be a treatment option when aspiration pneumonia is a recurrent problem in these children.TYPE OF STUDY: Cohort study.LEVEL OF EVIDENCE: Prognosis study-level I.

- Objective: To test the hypothesis that higher hospital volume decreases endoscopic and surgical re-intervention rates after antireflux surgery.Background: Antireflux surgery for gastro-esophageal reflux disease is followed by varying rates of re-interventions. Whether hospital volume influences re-intervention rates is uncertain.Methods: This population-based cohort study used nationwide data from Denmark, Finland, and Sweden for patients having undergone primary antireflux surgery. Hospitals were divided into tertiles based upon annual volume, that is, 3 equal-sized groups. The outcomes were 30-day surgical re-intervention, endoscopic re-intervention, and secondary antireflux surgery. Multivariable Cox regression provided hazard ratios (HRs) with 95% confidence intervals (CIs) for risk of the first outcome occurrence. Incidence rate ratios were calculated to count all outcome occurrences. All risk estimates were adjusted for age, sex, comorbidity, type of antireflux surgery, year of surgery, and country.Results: Among 33,060 patients and a median follow-up of 12 years after antireflux surgery, the frequencies of 30-day re-intervention, endoscopic re-intervention, and secondary antireflux surgery were 1.2%, 4.6%, and 7.0%, respectively. When comparing the highest with the lowest tertiles, higher hospital volume did not decrease HRs of 30-day re-intervention (adjusted HR = 1.14, 95% CI 0.73-1.77), endoscopic re-intervention (HR = 1.21, 95% CI 0.96-1.51), or secondary antireflux surgery (HR = 1.28, 95% CI 1.05-1.54), but rather increased point estimates. The incidence rate ratios showed similar patterns.Conclusions: Higher hospital volume of primary antireflux surgery may not decrease risk of endoscopic or surgical re-intervention, suggesting that centralization will not decrease rates of postoperative complications or recurrence of gastro-esophageal reflux disease.
