title: Prevention of Esophageal Strictures After Endoscopic Submucosal Dissection: A Promising Therapy Using Carboxymethyl Cellulose Sheets.
abstract: Esophageal stricture is one of the serious adverse events following endoscopic submucosal dissection (ESD). However, optimum preventive techniques are still lacking.
  
  
  
  Our primary objective was to evaluate the incidence of post-ESD esophageal stricture with the application of carboxymethyl cellulose (CMC) sheets. Secondary objectives were to determine the number of sessions of endoscopic balloon dilatation (EBD) required to resolve post-ESD strictures and the incidence rate of peri-operative adverse events.
  
  
  
  This was a pilot, single-center, prospective study. Seven patients who had high risks of developing post-ESD esophageal stricture were enrolled into our study. CMC sheets were applied to the mucosal defects immediately after the completion of ESD. Patients were monitored and reviewed after ESD to detect any adverse events.
  
  
  
  The incidence rate of post-operative stricture was 57 % (4/7 patients). Among patients who required EBD, the number of sessions performed was 2.8 ± 2.2. No serious post-operative adverse events were reported.
  
  
  
  The use of CMC sheets appears to be a safe and effective prophylactic treatment for esophageal stricture following extensive ESD.
