Modified Self-Expanding Plastic Stent for the Treatment of Refractory Benign Esophageal Strictures

Abstract

Self-expanding plastic stents (SEPSs) are increasingly used for the treatment of benign gastrointestinal strictures, because they may be extracted with substantially less tissue damage compared with self-expanding metal stents. However, the problem of a high rate of premature dislocation is still unsolved, especially in strictures where there is also extended prestenotic or poststenotic dilatation, or both. Acutely waisted SEPS, which are so far not available, are required to stent these strictures.
