Outcomes of Esophageal Self Dilation for Benign Refractory Esophageal Stricture Management
Study Details
Study Description
Brief Summary
Among patients with refractory benign esophageal stricture (RBES) who were treated endoscopically, we hypothesized the following:
-
Compared to a endoscopy as needed approach, esophageal self -dilation therapy (ESDT) decreases the number of endoscopic dilation, prolong dysphagia free interval
-
Esophageal self -dilation therapy is safe and well tolerated therapy
-
ESDT significantly lower the health cost in managing refractory esophageal stricture

Detailed Description
Benign esophageal strictures can be challenging condition to treat. The mainstay of treatment is endoscopic dilations. However, 30 to 40% of these strictures recur despite rigorous dilations. Although a consensus definition does not exist, a stricture is typically termed as a refractory benign esophageal stricture (RBES), when there is a failure to maintain luminal patency after at least 5 endoscopic dilations.
Patients with RBES are extremely difficult to manage and the current armamentarium includes repeated endoscopic dilations, corticosteroid or mitomycin C injections, incisional therapy, and/ or temporary stent placement. These procedures are costly, their efficacy can be short-lived, and are associated with great burden both for the patient and clinician.
Esophageal self -dilation therapy (ESDT) is where the patient learns to pass a polyvinyl dilator orally on a routine basis. In past, smaller studies, ESDT appears to be effective for RBES, reducing the number of endoscopic dilations from an average of 21.7 to an average of 1.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: Endoscopic Dilation Patients randomized to the observation group will undergo repeat upper endoscopy with dilation as needed if their dysphagia relapses. A relapse will be considered if a patient developed solid food dysphagia at least once a week. |
Procedure: Upper Endoscopy with Dilation
Patients will undergo repeat endoscopy and dilation as needed if their dysphagia relapse which is the current standard of care.
|
| Active Comparator: Esophageal Self Dilation Patients will be instructed to start Esophageal self dilation twice a day. If dysphagia is adequately controlled, and there was no resistance with passing the dilator, patients will be asked to decrease the frequency of ESDT to daily, weekly, and monthly over an average period of 6 months. |
Device: Esophageal self dilation
Esophageal self dilation therapy (ESDT), where the patient learns to pass a polyvinyl dilator orally on a routine basis teaching will take over 1-3 training sessions by one of two esophageal physicians and a nurse. Patients will be instructed to start Esophageal self dilation twice a day. If dysphagia is adequately controlled, and there was no resistance with passing the dilator, patients will be asked to decrease the frequency of ESDT to daily, weekly, and monthly over an average period of 6 months as directed by the esophageal care team.

Outcome Measures
Primary Outcome Measures
- The tolerability of esophageal self dilation compared to observation defined as number of endoscopic interventions [6 months]
The number of patients who remained free of endoscopic therapy between the two groups
Secondary Outcome Measures
- Esophagram [6 months]
The esophagram is an x-ray test that assesses the diameter of the esophagus. Patients whose esophagus achieves and remains 10-12mm
- Mayo Dysphagia Questionnaire 30 Day (MDQ-30) [1 year]
The MDQ-30 provides a series of questions for patients regarding their swallowing difficulties over the past 30 days. A total score of 40 or higher indicates positive for dysphagia, and a total score of 15 or lower is considered negative for dysphagia. Scores between 15 and 40 are considered indeterminate for dysphagia.
- Upper endoscopy: Number of endoscopic interventions [6 months]
Participants who experience dysphagia more than once per week will return for an upper endoscopy and dilation
