Esophageal Adenocarcinoma After Antireflux Surgery in a Cohort Study From the 5 Nordic Countries
Objective:
We aimed to clarify the long-term risk development of EAC after antireflux surgery.
Summary of Background Data:
Gastroesophageal reflux disease (GERD) increases EAC risk, but whether antireflux surgery prevents EAC is uncertain.
Methods:
Multinational, population-based cohort study including individuals with GERD from all 5 Nordic countries in 1964–2014. First, EAC risk after antireflux surgery in the cohort was compared with the corresponding background population by calculating standardized incidence ratios (SIRs) with 95% confidence intervals (95% CIs). Second, multivariable Cox proportional hazards regression, providing hazard ratios (HRs) with 95% CIs, compared EAC risk in GERD patients with antireflux surgery with those with nonsurgical treatment.
Results:
Among 942,071 GERD patients, 48,863 underwent surgery and 893,208 did not. Compared to the corresponding background population, EAC risk did not decrease after antireflux surgery [SIR 4.90 (95% CI 3.62–6.47) 1–
