title: Impact of a self-expanding, plastic esophageal stent on various esophageal stenoses, fistulas, and leakages: a single-center experience in 39 patients.
abstract: BACKGROUND
  In this study, we describe our experience with the use of a self-expanding, covered, plastic esophageal stent (SEPS). The majority of placements were difficult to treat situations, i.e., proximal or extremely proximal stent release or emergency cases in the intensive care unit.
  
  
  METHODS
  Thirty-nine patients were treated by insertion of a SEPS by endoscopic or radiologic guidance for the following: malignant stenosis (n = 22), malignant fistula (n = 8), benign stenosis after treatment for malignant disease (n = 6), benign fistula (n = 2), and perforation or leakage after surgery of the esophagus (n = 5).
  
  
  RESULTS
  Stent placement was technically feasible in all patients. In patients with a stenosis, esophageal passage was achieved in 92.8%. Fistulas, perforations, and leakages were sealed in 73.3%. In 6 patients (15.4%), the stent was electively removed because of the completion of the therapy. Complications included respiratory insufficiency, mediastinal emphysema, and tracheal impression in one patient each; a new fistula in two patients; bleeding in 3 patients; stent-induced ulcers in two patients; and stent migration in 8 patients.
  
  
  CONCLUSIONS
  The therapeutical success and the complication rate after SEPS placement are similar to that reported for self-expanding metal stents. In addition, the SEPS can be readily removed, and the costs are significantly lower.
