Abstract
Objective. The mortality associated with malignant complications of gastroesophageal reflux disease (GERD) is well recognized. The aim of this systematic review was to assess the less well-examined mortality associated with GERD and its non-malignant complications, including esophageal erosions, ulcers, bleeding, perforation and strictures. Material and methods. Studies reporting mortality in GERD and its non-malignant complications were identified via systematic PubMed searches, and previously unpublished population mortality statistics from public access databases. Results. Three countries were examined (USA, UK, Finland). Cohort studies (n=3) in the UK showed a 1.16- to 1.6-fold increase in risk of death in individuals with GERD compared with the general population, the majority of deaths being due to cardiac disease. Population data indicate that GERD and its likely esophageal complications were the cause of death in 685 and 521 cases, respectively, in the USA (year: 2003) (age-adjusted mortality: 2.3/million and 1.8/million, respectively), and in 36 and 349 cases, respectively, in England and Wales (2004) (0.6/million and 5.4/million, respectively). In Finland (2000), GERD-related mortality was 4.6/million. Mortality from GERD and its likely esophageal complications increased with age, and was between 1.2-fold and 1.8-fold higher in men than in women. Cohort studies in the USA are inconsistent on mortality risk associated with surgical therapy. Time-trend data suggest that mortality from GERD and its non-malignant complications has been increasing. Conclusions. Data from Europe and the USA show that GERD and its non-malignant complications can on rare occasions cause death.
