BACKGROUND AND AIMS

BougieCap (Ovesco Endoscopy AG, Tübingen, Germany) is a new device that allows optical and tactile feedback during stricture dilation of the upper gastrointestinal tract. We evaluated the technical feasibility, clinical efficacy, and safety of a one-time esophageal stricture dilation using BougieCap in adults with eosinophilic esophagitis (EoE).

METHODS

EoE patients prospectively included in the Swiss EoE Cohort were dilated with BougieCap in case of the presence of esophageal strictures (esophageal diameter ≤14 mm) and stricture-related symptoms. Symptoms were assessed before and 2 weeks after a single dilation session using the validated Eosinophilic Esophagitis Activity Index Patient Reported Outcomes (EEsAI PRO)instrument (score ranges from 0-100 points).

RESULTS

Fifty patients (70% male, median age 41 years, median disease duration of 4 years, 50% treated with swallowed topical corticosteroids, 10% with proton pump inhibitors, 14% with combined swallowed topical corticosteroids plus proton pump inhibitors, 14% with elimination diet, 12% without anti-eosinophil therapy) were evaluated. Endoscopic bougienage was technically successful in 100%. Median esophageal diameter increased from 12 mm (IQR 12-13) to 16 mm (IQR 16-16, p<0.001)). Median symptom severity dropped from 32 points (IQR 27-41) to 0 (IQR 0-10, p<0.001) at 2 weeks post dilation. In one patient the BougieCap was temporarily lost after stricture dilation in the hypopharynx but could be retrieved. No severe adverse events were reported.

CONCLUSIONS

In adults with EoE, endoscopic treatment of esophageal strictures using BougieCap is technically feasible, safe and offers significant symptomatic improvement in the short term.
