• W2002078043 abstract "BackgroundThe new generation of expandable plastic esophageal stents (Polyflex; Boston Scientific, Natick, MA), combine the features of plastic and self-expanding metallic stents. The main objective of this study is to evaluate our initial experience with Polyflex expandable stents in the treatment of esophageal disease from two institutions.MethodsA total of 58 Polyflex stents were placed in 38 patients over a two-year period. There were 24 men and 14 women, with a median age of 63 years (range, 25 to 83). The most common indication for placement was an esophageal stricture in 25 patients (66%); other causes included leak in 8 (21%) and tracheoesophageal fistula (TEF) in 5 (13%). We evaluated the hospital course, complications, and outcomes.ResultsThe median postoperative stay was one day. Complications included migration in 38 stents (63%) (28 patients; 73%), retrosternal chest discomfort in nine, reflux in four, airway obstruction in one, and food impaction in three. Continued leak or a persistent TEF occurred in five patients (38%). Reintervention was required predominantly due to migration of the stent at a mean interval of 46 days (range, 1 to 353). Patients with dysphagia improved significantly with dysphagia scores (1 = no dysphagia; 5 = unable to swallow saliva) improving from 3.44 to 2.15 (p < 0.0001).ConclusionsPolyflex stents were effective in the relief of dysphagia due to strictures. They were less effective in esophageal perforations or leaks. Their primary disadvantage is a high migration rate and further improvements in design are required to decrease this high incidence of migration.
