Official title
Early Versus Late Endoscopic Temporary Stenting for Management of Refractory Benign Esophageal Strictures
Overview
This project is being done to compare two current treatment clinical options for management of RBES: 1) Frequent dilations followed by temporary esophageal stent placement if dilations fail, or 2) Early stent placement followed by dilations
Detailed description
This study aims to explore the safety and effectiveness of two clinical treatment approaches used to manage RBES patients-Temporary early-stent placement versus late stenting.
For normal swallowing, the esophagus (food pipe) lumen should be equal to or more than 14 mm in diameter. In those with stricture (narrowing) of the esophagus from benign causes, initial endoscopic management is serial sessions of dilation (stretching) to achieve and maintain a diameter of ≥14mm. Many strictures may not respond to this approach (refractory). Esophageal stents (18 mm - 23 mm diameter) temporarily placed for 2 weeks using an endoscope are also used dilate and remold the stricture. While in place, patients can swallow. This can save the patient from undergoing repeated dilations. Stents can be placed either late in the process of management after several traditional dilations have failed or early in the management to rapidly achieve a diameter of ≥14 mm and then continuing traditional dilations.
Although either of above two approaches can be used for the clinical management of RBES, in this study the investigators plan to randomly assign patients to start with one of the two approaches and compare outcomes.
Interventions
- Device Fully covered self-expandable metal esophageal stent
Esophageal stent placement for patients with benign esophageal strictures not responding to endoscopic dilations.
Primary outcome measures
- Time to achieve esophageal luminal diameter to ≥14 mm [Time frame: From enrollment to follow up, up to 2 years]
Secondary outcome measures (2)
- Adverse event rate [Time frame: From enrollment to follow up, up to 2 years]
- Recurrence rate of esophageal stricture [Time frame: From enrollment to follow up, up to 2 years]
