Abstract

Study objectives: A frequent complication of the widely used Dumon silicone stent is its tendency to migrate when used in tracheal stenosis, We compared the clinical efficacy and complications (including migration) of the Dumon stent with a screw-thread stent, a device with an increased stent-to-wall contact surface and, theoretically, less tendency to migrate. Design: Retrospective case analysis,Setting: Academic hospital. Materials and methods: Forty-six patients with tracheal stenoses (23 benign and 23 malignant) requiring the placement of 50 stents (29 Dumon and 21 screw-thread) were studied, In 26 patients Dumon stents were used, and in 20patients screw-thread stents were used. Both patient groups had comparableclinical and stenosis-related characteristics. Results: Stent insertion and follow-up were uneventful in both the Dumon and the screw-thread insertions, respectively: 62% vs 67% (not significant). There were seven migrations in the Dumon group, compared to only one migration in the screw-dread group, respectively: 24% vs 5%. This difference didnot reach statistical significance (p = 0.1), All of the migrations occurred in the benign stenosis group, and none occurred in the malignant-stenosis group, respectively: 8 of 23 vs 0 of 23, p = 0.004. Within the benign-stenosis group, the Dumon stent had a significantly increased risk for migration when compared to the screw-thread stent, respectively: 7 of 13 vs 1 of 11, p = 0.033. Conclusions: The screw-thread stent and the Dumon stent are equally effective in the management of tracheal stenosis, There is a general trend towarda decreased migration rate, and a significantly lower risk for migration in patients with benign tracheal stenosis. The (less expensive) screw-threadstent may represent an attractive alternative in the management of tracheal stenosis in general, and may be preferable to the Dumon stent in treatingbenign tracheal stenosis.
