Abstract
BACKGROUND: Eosinophilic esophagitis (EoE) causes esophageal narrowing and strictures, but factors that modify the severity of strictures and requirement for subsequent dilation are not well described. The aim of this study was to identify characteristics that impact the need for repeat (> 1) esophageal dilations in EoE patients. METHODS: This was a single center retrospective cohort study over a 12-year period (September 2005-October 2017). Patients were identified using ICD9, ICD10, and CPT codes for esophageal dilation, eosinophilic esophagitis, and esophageal obstruction. Data for EoE clinical characteristics, treatments, and BMI were extracted and correlated to the number of esophageal dilations and time elapsed between dilations. RESULTS: Of the 21 patients who met inclusion criteria, 11 (52%) had at least two dilations and 9 (43%) had three dilations. There was no differences baseline demographics between patients who needed ≥ 2 vs. those who needed one dilation. However, patients with a BMI > 30 had a significantly longer median time to second dilation compared to non-obese patients (4.9 years vs. 1.8 years; p = 0.027). Stratification by either high dose PPI or inhaled steroid use did not change this result. CONCLUSIONS: EoE patients with strictures who are obese have a reduced requirement for subsequent esophageal dilation. While the mechanism for this is not clear, increased attention of non-obese patients with fibrostenotic EoE is indicated as they are at higher risk for recurrent strictures.
