Esophageal Stricture
Conditions
Keywords
Esophageal stricture, Mitomycin, Triamcinolone, Dysphagia
Brief summary
To compare the efficacy of steroid injection versus topical mitomycin-C in the treatment of pediatric benign recurrent esophageal strictures. The rationale for this study is to compare the two therapeutic options in order to measure their effectiveness, in terms of improvement of Dysphagia Severity Score (DSS).
Detailed description
After taking approval from the Institutional Review Board of the university; and taking the informed consent from parents, patients fulfilling the inclusion and exclusion criteria will be enrolled in the study. They will be then randomly allocated into two groups; group A and group B. Patients in Group A will be treated with esophageal dilation with a CRE balloon (controlled radial expansion balloon). After adequate dilation of stricture, injection Mitomycin will be applied to the narrowest portion of the stricture. Patients in Group B will be treated with esophageal dilation with a CRE balloon in the same manner. After adequate dilation of stricture, Triamcinolone injection will be injected into the narrowest portion of the stricture, using a sclerotherapy injector. Dysphagia Severity Score will be noted at start of intervention, at 2 weeks after intervention and at 6 weeks post- intervention.
Interventions
PROCEDUREBalloon Dilation + Topical Mitomycin
Patients with recurrent esophageal strictures in Group A will undergo endoscopy and balloon dilation with a CRE balloon, followed by injection Mitomycin applied topically at stricture site (post dilation)
PROCEDUREBalloon Dilation + Injection Triamcinolone
Patients with recurrent esophageal strictures in Group B will undergo endoscopy and balloon dilation with a CRE balloon, followed by injection Triamcinolone, injected with a sclerotherapy injector, at stricture site (post dilation)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Effectiveness measured in terms of improvement in Dysphagia Severity Score (DSS) | 6 weeks | Patients in both groups (group A and group B) will be followed and mean dysphagia severity score will be noted at 0, 2 and 6 weeks of intervention in both the groups. Improvement in dysphagia will be monitored via a validated Dysphagia Severity Score (DSS). It is as follows: 0 Able to eat normal diet/no dysphagia 1. Able to swallow some solid foods 2. Able to swallow only semi solid foods 3. Able to swallow liquids only 4. Unable to swallow anything/total dysphagia |
