Abstract
BACKGROUND: The widespread use of proton pump inhibitors for gastro-oesophageal reflux disease could result in a decline in new as well as recurrent gastro-oesophageal reflux disease-related oesophageal strictures. The temporal trends of strictures have not been examined in population-based studies. METHODS: To examine the temporal trends in strictures, we calculated the age-adjusted incidence rates of new oesophageal strictures with or without oesophageal dilation in a sample of Medicare beneficiaries between 1992 and 2000. We also examined recurrent dilations recorded at least 3 months after a new stricture or the preceding recurrent stricture. RESULTS: The age-adjusted rates for strictures accompanied with dilation declined by approximately 11% from 215 per million to 192 per million. New oesophageal strictures with dilation declined as a proportion of all upper endoscopies procedures (from 2.6% to 1.9%). Recurrent dilation within 1 year declined dramatically from 16% (9.5% CI: 12.5-20.3) in 1992 to 8% (95% CI: 4.43-10.62) in 2000. In multivariable proportional hazards model, there was a 30% risk reduction of recurrent oesophageal strictures. CONCLUSIONS: This population-based study indicates that the incidence of new as well as recurrent oesophageal strictures has been declining. In the face of rising incidence of other gastro-oesophageal reflux disease-related complications, it is important to understand the explanation of the present observations.
