Brief summary
The investigators conduct this phase II study to evaluate safety and effectiveness of EGCG in patients with dysphagia. Swallowing-related dysphagia and pain scores were recorded using the numerical rating scale (NRS) daily . Barium meal radiography was utilized to measure the luminal size and the length of the lesion area both before and after a week of EGCG treatment. The scales are translated into Chinese and guides in Chinese are developed instructing how to use the scales and perform the assessments.
Interventions
Epigallocatechin-3-gallate is administered in a solution with a concentration of 4400 umol/L

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Choking symptom objective response rate | baseline and up to 7 days post-treatment | Choking when swallowing was assessed by Stooler's dysphagia score (0-4, with 0 being none and 4 being completely unable to feed orally) |
| Pain symptom objective response rate | baseline and up to 7 days post-treatment | Pain when swallowing was assessed by numerical rating scale (0-5, with 0 being none and 5 being worst pain imaginable) |
| Imaging objective response rate | Change from Baseline esophageal stenosis size at 7 days | Response rate of esophageal stenosis was determined by X-ray barium meal examination and/or contrast-enhanced CT |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| prealbumin change | baseline and up to 7 days post-treatment | The prealbumin values were tested by biochemical analysis |
| Albumin change | baseline and up to 7 days post-treatment | The albumin values were tested by biochemical analysis |
| Number of Participants with Adverse Events | baseline and up to 7 days post-treatment | participants will be followed for the duration of EGCG treatment |
