Abstract

Background: Several small series have suggested an increased risk of complications associated with esophageal dilation in patients with eosinophilic esophagitis (EoE). Objective To quantitate the risk and identify risk factors for esophageal complications in dilation in EoE patients. Design Retrospective, uncontrolled, single-center study. Setting Tertiary referral hospital. Patients A total of 161 EoE patients (mean ± standard deviation age 44.3 ± 15.3 years, 112 men, 49 women, 150 white patients, 10 unknown, 1 Asian). Interventions Through-the-scope balloon or Savary dilation of EoE. Main Outcome Measurements The rate of complications defined as deep mucosal tear, major bleeding, or perforation, and determination of risk factors for complications. Results A total of 293 dilations were performed in 161 patients. Complications reported were deep mucosal tear in 9.2% (n = 27), major bleeding in 0.3% (n = 1), and immediate perforation in 1.0% (n = 3). All patients with perforations were successfully treated medically without surgery (mean ± standard deviation hospital stay 5.3 ± 3.2 days). Factors associated with an increased risk of complications were luminal narrowing in the upper (odds ratio [OR], 5.62; 95% CI, 2.07-15.26; P < .001) and middle third of the esophagus (OR, 4.93; 95% CI, 1.64-14.83; P < .005) compared with lower third, luminal stricture unable to be traversed with a standard upper endoscope (OR, 2.48; 95% CI, 1.06-5.83; P = .037), and use of Savary dilator (OR, 2.63; 95% CI, 1.18-5.83; P = .018). Limitations Retrospective design, uncontrolled study. Conclusions Deep mucosal tears are common after dilation (9%), but the risk of immediate transluminal perforation with EoE is approximately 1%. The risk of severe complications is increased in patients with more proximal stricture and strictures that initially prevent endoscope passage.
