BOUGIE CAP Cohort Study, Esophageal Strictures
Summary
The NIH ClinicalTrials.gov registry has posted an observational cohort study (NCT07534800) evaluating the BougieCap™ device (Ovesco Endoscopy AG) for treating benign and short esophageal strictures. The study aims to assess the device's performance and short-term effectiveness on dysphagia. This is an informational registration entry for an ongoing clinical study.
What changed
The NIH ClinicalTrials.gov registry added a new observational cohort study (NCT07534800) examining the BougieCap™ device manufactured by Ovesco Endoscopy AG for endoscopic dilation of short benign esophageal strictures. The study will evaluate device performance and short-term effectiveness on dysphagia symptoms.\n\nHealthcare providers and clinical investigators conducting gastroenterology or gastrointestinal research may use this registry information to identify related studies, understand current research landscapes for esophageal stricture treatments, or consider patient referrals. The study does not create compliance obligations for manufacturers, providers, or patients—its purpose is research documentation and transparency under clinical trial registration requirements.

Cohort Study on the Use of the BOUGIE CAP™ Device for the Treatment of Benign and Short Esophageal Strictures
Observational NCT07534800 Kind: OBSERVATIONAL Apr 16, 2026
Abstract
Benign esophageal strictures are a common condition with multiple and varied causes. Esophageal strictures are manifested by the appearance of dysphagia, usually when the reduction in the esophageal lumen is greater than 50%. Malnutrition and aspiration pneumonia can also occur. Quality of life can thus be significantly impaired. To date, there are multiple techniques for treating strictures. Dilation (hydrostatic or bougie) is the historical first-line treatment. The effectiveness of the 2 historical dilation methods (balloon vs bougie) is comparable, with no difference in terms of adverse effects, with robust literature on the subject. There is a new device called the BougieCap™ (Ovesco Endoscopy AG, Tubingen, Germany). It is a short, tapered, conical-shaped transparent cap that attaches to the end of the endoscope. This cap allows the treatment of short strictures, with direct visualization during dilation.
The results of this research will be used to better evaluate the performance of the Bougie Cap™ in the endoscopic dilation of short benign esophageal strictures as well as its short-term effectiveness on dysphagia. Another advantage of this device, particularly compared to older techniques, is its ecological potential (lower packaging weight).
