Study summary

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

Read the 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.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: 6 months

  2. 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.

    Time frame: 1 day

Secondary outcomes

  1. Esophageal pain, measured with VAS during follow-up after stent placement

    Pain will be measured with the VAS during follow-up

    Time frame: 6 months

  2. Recurrent dysphagia, measured with Ogilvie dysphagia score, during follow-up

    Recurrent dysphagia during follow-up

    Time frame: 6 months
