Treatment of Airway and Esophagus Stenosis with Stent Review. Stent Placement in Patients with Benign Pharynx and Cervical Esophageal Stenosis.

Over a 3-year period in our department, 7 patients underwent stent treatment for a benign stenosis of the pharynx and cervical esophagus. The most common complication of an expandable metallic stent is stent-induced stenosis caused by granulation tissue. The use of expandable metallic stents should be until 2 weeks because of the granulation tissue obstruction at the terminal ends. The through-bougie esophageal prosthesis can be used over 3 years without complication. The authors recommend the through-bougie esophageal prosthesis for cervical esophageal fistula. Esophagus-friendly materials may well include new stents, such as an expandable silicon stent.
