Summary
Brief summary (as posted)
cytosponge has good diagnostic efficacy in the diagnosis of esophageal cancer, and is more safe, economic and comfortable. It is expected to replace gastroscope in the surveillance after endoscopic submucosal dissection to a certain extent. At present, there is no relevant research at home and abroad. This study plans to establish a large sample cohort based on the collaborative research network established earlier, prospectively include 1000 patients who received endoscopic submucosal dissection for esophageal squamous cell carcinoma and compare the effectiveness and safety of cytosponge and gastroscope in surveillance after endoscopic submucosal dissection for esophageal squamous cell carcinoma through self -comparison.

- description
- Participants were instructed to place the capsule near the root of the tongue and fold the string in their mouths, leaving approximately 20 cm of string outside, with a blue mark on the string right at the lips. The capsule was then swallowed with water, and the end of the string was held out of the mouth. Participants were then asked to slowly drink 150-200 mL of 50°C water in approximately 2 minutes to allow the capsule to dissolve so that the sponge mesh inside was released. The device was then slowly withdrawn up the esophagus by pulling the string. The retrieved and expanded cell collection material was put in preservative fluid (Froeasy Technology, Nanjing, China) and transferred to the cytology laboratory at room temperature.
