title: Removable, fully covered, self-expandable metal stents for the treatment of refractory benign esophagogastric anastomotic strictures.
abstract: The use of metal stents for malignant esophageal strictures for palliation is well accepted. However, utilization of metal stents for benign esophageal diseases has been controversial. Given the availability of removable, fully covered, self-expandable metal stents (RFCSEMSs), this study was undertaken to evaluate the effectiveness and safety of RFCSEMSs in patients with refractory benign esophagogastric anastomotic strictures. Twenty-four patients with RFCSEMSs were enrolled in this study. All patients had undergone endoscopic Savary-Gilliard bougie dilatation five times or more but there was no significant improvement in symptoms. For all 24 patients, the symptom of dysphagia was alleviated significantly while the stent was in place and for a short time after stent removal, and dysphagia scores decreased from 3-4 to 0-1. After 12 months of follow-up, 18 patients were free from dysphagia but the other 6 patients still suffered obvious dysphagia. RFCSEMSs are still not perfect and can induce some complications. The treatment failure rate of restenting was remarkably high after the first failure. Given that effective methods for treating refractory stricture have not been found, RFCSEMSs could be considered for treating refractory benign esophagogastric anastomotic stricture.
