Why is this study being done?

Esophageal stricture (ES) formation is a widely recognized adverse event of radical EMR and ESD. Indeed, ES is the most common complication of radiofrequency ablation (RFA) for Barrett's esophagus (BE), with a reported incidence ranging from 5% to 12%. A single-center retrospective study reported ES formation in 67% of 73 patients with EMR of at least 50% of their esophageal circumference. Similarly, the incidence of ES development after ESD is between 70-90% when the mucosal defect involves more than three-quarters of the esophageal circumference. In aggregate, the extent of the esophageal mucosal defect following endotherapy appears to be the most consistent predictor of ES formation. Prevention of ES development following endotherapy can significantly improve a patient's quality of life and possibly reduce the potential risks and costs associated with treatment of ES with repeated endoscopic balloon dilations (EBD). Glucocorticoids have been evaluated as a potential preventive therapy for ES based on their anti-inflammatory properties and inhibitory effects on collagen deposition. Oral prednisolone has been shown to be effective as a preventive strategy for ES formation. However, prolonged use of systemic oral steroids can be associated with multiple adverse effects. Budesonide is a synthetic steroid with topical anti-inflammatory properties and high first-pass metabolism; thus, potentially less systemic absorption and side effects. Most recently Mayo Clinic Rochester developed a new budesonide capsule formulation. Alike viscous budesonide the budesonide capsule can be opened and the powder can be mixed with honey or pancake syrup. A similar formulation is currently used in pilot studies for treatment of eosinophilic esophagitis. The advantage of budesonide capsule is the improve taste in comparison to viscous budesonide originating from budesonide respules which is unpalatable. Study aims: 1. The aim of this study is to prospectively record our experience with budesonide for the prevention of esophageal stricture formation after endotherapy (mucosal resection, submucosal dissection) as part of routine medical care. 2. The data will be compared with outcomes with well-annotated historical controls that underwent similar procedure with similar follow up but without budesonide exposure. 3. If sufficient efficacy is seen, these data will be used to plan a prospective controlled clinical trial. All patients in the study group will receive standard medical care and no experimental interventions will be performed.
