Placement of the Evolution® Esophageal Stent for benign or malignant strictures, fistulas, perforations or leaks with the intention of removal

Evolution® Esophageal Stent - Fully Covered

John Vargo, M.D., M.P.H.

The CLARITY study is a clinical trial approved by US FDA to study the removal of the Evolution® Esophageal Stent-Fully Covered in malignant and benign indications.

Removal of the Evolution® Esophageal Stent - Fully Covered

Clinical Investigation to Evaluate Removal of the Evolution® Esophageal Stent - Fully Covered

The study design allowed for 130 patients to be enrolled to ensure that 58 patients had an attempted endoscopic stent removal between 7 days and 6 months in order to assess the primary measure as per sample size calculation. Therefore, the first 58 patients (malignant or benign lesions) with data submitted regarding attempted endoscopic stent removal are included in this outcome measure. Successful stent removal is one in which the study stent is completely removed from the patient during a single endoscopic procedure with the wire mesh integrity maintained such that the stent can be removed in one contiguous piece. Additionally, successful stent removal includes no tissue damage or hemorrhage visible during the retrieval procedure that is both related to the endoscopic stent removal and requires immediate treatment.

The rate of clinical success in patients with strictures that showed improvement or relief of dysphagia symptoms or a seal sufficient to enable oral intake in patients with fistulas, perforations, or leaks.
