PURPOSE: Tracheoesophageal fistula often need surgery. But some patients can not endure surgery. Recurrence after operation is also troublesome. Airway implantation of stent coated with silicon membrane is useful in treating tracheoesophageal fistula. But sometimes it failed due to thin membrane. Our objectives were to evaluate the efficacy and safety of airway stent with double membranes in treating tracheoesophageal fistula.
METHODS: From 7/2008 to 3/2012, four patients with tracheoesophageal fistulae, 3 due to esophageal cancer and 1 due to surgery for esophageal-cardiac achalasia, received an airway stent implantation. The nickel-titanium alloy stents were coated with inner silicon membrane and outer polytetrafluoroethylene membrane. The outer membrane was sewed to stents on distal side with suture silk. After airway stenting, the patients were followed up. The efficacy and side effects were evaluated.
RESULTS: One patient received airway stent with a silicon membrane only before implantation of stent with double membranes. About 2 months later, the membrane was destroyed. Eating bucking and pulmonary infection recurred. After implantation of stents with double membranes, eating bucking disappeared soon in all four patients. Two patients with esophageal cancer died 3 and 6 months later, the other two patients are still alive. No recurrence occurred in all four patients. Severe complications were not observed.
CONCLUSIONS: Airway stent with double membranes is effective and safe in treating tracheoesophageal fistula. Stents with double membranes may be more useful than one layer of membrane on sealing up fistula.
CLINICAL IMPLICATIONS: Although improvement should be made, our results suggest that airway stent with double membranes is alternative to tracheoesophageal fistula treatments.
