Refractory benign esophageal strictures: extending the role of expandable stents.

Abstract

It is challenging to manage benign refractory esophageal strictures. We have now moved on from instant dilators to prolonged gradual dilatations using expandable stents that can be removed or biodegradable after a period of time left in situ. Recent published experience and the present study by Dua et al. have demonstrated the feasibility of this technique. However, not all strictures are the same and several issues need to be addressed including stent migration, stent duration, and the sub-group of patients who will benefit most.
