    Abstract:
    BACKGROUND AND AIMS: Esophageal stricture is a common adverse event after endoscopic submucosal dissection (ESD) when it involves the entire circumference of the esophagus. We aimed to assess the effectiveness and safety of endoscopic transplantation of autologous esophageal mucosa in preventing stricture formation after circumferential ESD. METHODS: Nine patients who underwent circumferential ESD for early esophageal cancer were enrolled. After the patients underwent ESD, autologous esophageal mucosal patches were attached to the ulcer surface by using hemoclips and were then fixed with a covered metal mesh stent. The stent was removed 7 days after the procedure. The patients were followed up with endoscopy at scheduled times. RESULTS: Epithelialization occurred within a median of 7.1 days, with a graft survival rate of 96.5%. Strictures occurred at a mean of 24.7 days (range 18-34 days) after the procedure. The median number of endoscopic balloon dilatation sessions was 2.7 (range 0-6). CONCLUSIONS: Transplantation of autologous esophageal mucosa could be a safe way of relieving the severity of esophageal stricture after circumferential ESD.
