Other
Other related information In this study, we obtain esophageal specimens using a brush for biliary cytology via endoscopic forceps channel. we are going to perform 16S rRNA gene amplicon sequencing analysis in 5 patients with esophageal squamous cell carcinoma before endoscopic submucosal dissection and 15 patients with achalasia before and after per-oral endoscopic myotomy. We also investigate the relationship between inflammation of the esophageal epithelium and esophageal microbiota in these patients.
