Outcomes of Esophageal Dilation in Eosinophilic Esophagitis: Safety, Efficacy, and Persistence of the Fibrostenotic Phenotype.

ABSTRACT: Esophageal dilation is commonly performed in eosinophilic esophagitis (EoE), but there are few long-term data. The aims of this study were to assess the safety and long-term efficacy of esophageal dilation in a large cohort of EoE cases, and to determine the frequency and predictors of requiring multiple dilations.We conducted a retrospective cohort study in the University of North Carolina EoE Clinicopathological Database from 2002 to 2014. Included subjects met consensus diagnostic criteria for EoE. Clinical, endoscopic, and histologic features were extracted, as were dilation characteristics (dilator type, change in esophageal caliber, and total number of dilations) and complications. Patients with EoE who had undergone dilation were compared with those who did not and also stratified by whether they required single or multiple dilations.Of 509 EoE patients, 164 were dilated a total of 486 times. Those who underwent dilation had a longer duration of symptoms before diagnosis (11.1 vs. 5.4 years, P<0.001). Ninety-five patients (58%) required >1 dilation (417 dilations total, mean of 4.4±4.3 per patient). The only predictor of requiring multiple dilations was a smaller baseline esophageal diameter. Dilation was tolerated well, with no major bleeds, perforations, or deaths. The overall complication rate was 5%, primarily due to post-procedural pain. Of 164 individuals dilated, a majority (58% or 95/164) required a second dilation. Of these individuals, 75% required repeat dilation within 1 year.Dilation in EoE is well-tolerated, with a very low risk of serious complications. Patients with long-standing symptoms before diagnosis are likely to require dilation. More than half of those dilated will require multiple dilations, often needing a second procedure within 1 year. These findings can be used to counsel patients with fibrostenotic complications of EoE.

Project description:ObjectivesEosinophilic esophagitis (EoE) is a chronic inflammatory condition that causes esophageal remodeling and stricture formation. We compared the clinical course of symptoms, endoscopic findings, histology, and changes in phenotype over time in EoE patients with inflammatory and fibrostenotic phenotypes.MethodsData were obtained from EoE patients from three medical centers and followed prospectively. Endoscopic features and histology from index and follow-up endoscopies were recorded. Behavior was classified as inflammatory if endoscopic findings demonstrated furrows or white plaques and as fibrostenotic if endoscopic findings included fixed rings or strictures.ResultsTwo hundred and fifty-six EoE patients were included in the analysis. The mean age was 32±18 years, 25% of patients were <18 years, 89% of patients were Caucasians, and 74% of patients were male. The mean duration of symptoms before diagnosis was 6.8±7.2 years with a follow-up of 1.7±1.9 years (maximum follow-up of 12 years). Fifty-four percent of patients presented with fibrostenotic EoE, whereas 46% presented with inflammatory EoE. Patients with inflammatory disease were younger than those with fibrostenotic disease (24±19 vs. 39±15 years, P<0.001). Patients with fibrostenotic disease had a longer duration of symptoms than those with inflammatory disease (8.1±7.7 vs. 5.3±6.3 years, P=0.002). Over the study period, 47 (18%) had remission of inflammatory EoE, 68 (27%) continued to have inflammatory disease, 74 (29%) continued to have fibrostenotic disease, 65 (25%) fibrostenotic patients had regression of fibrosis, and 2 patients (1%) progressed from inflammatory disease to fibrostenotic disease. Patients who had regression from their fibrostenosis were more likely than patients who continued to demonstrate fibrostenosis to have a decrease in proximal (54% vs. 32%, P<0.001) and distal (70% vs. 38%, P<0.001) eosinophilia.ConclusionsMost EoE patients maintained their phenotype or had an improvement with <1% progressing from inflammatory to fibrostenosis. This suggests that early therapeutic strategies aimed at controlling inflammation may interrupt, decrease, or prevent the remodeling fibrosis in EoE.
