BD-Covered Stent for Benign Esophageal Strictures: a Safety and Feasibility Study (BIDARCA)

A non-randomized prospective clinical, pilot study in a single centre assessing the safety and feasibility of the esophageal biodegradable covered stent for refractory benign esophageal strictures with or without fistulae

Study Overview

• Status: Unknown
• Conditions: Benign Esophageal Stricture
• Intervention / Treatment: Device: BD-Covered esophageal stent

Detailed Description

A non-randomized prospective clinical, pilot study in a single centre assessing the safety and feasibility of the esophageal biodegradable covered stent for refractory benign esophageal strictures with or without fistulae. The follow-up will be 6 months form implantation. After 3 months a control endoscopy will take place to evaluate stent and degradation process.

• Study Type: Interventional

Arms and Interventions

Participant Group / Arm	Intervention / Treatment

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Incidence of treatment associated adverse events during follow-up (safety)	Short term (within 7 days after treatment) and long term (after 7 days) major complications and minor complications. Major complications are defined as life threatening and severe complications such as perforation, haemorrhage, fistula formation and severe pain. Minor complications are defined as non-life threatening or moderately severe pain and gastroesophageal reflux.	6 months
BD-Covered stent placement (feasibility): (1) ease of deployment at intended esophageal location and, (2) incidence of device related adverse events at moment of stent placement	Technical success is defined as ease of deployment and placement of the BD-Covered stent at the required esophageal location.	1 day

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Esophageal pain, measured with VAS during follow-up after stent placement	Pain will be measured with the VAS during follow-up	6 months
Recurrent dysphagia, measured with Ogilvie dysphagia score, during follow-up	Recurrent dysphagia during follow-up	6 months
