Abstract
Endoscopic endoprosthesis is well established as a cheap, fast and durable procedure for palliation of malignant dysphagia. But the placement of conventional endoprosthesis is difficult and is associated with significant complications such as hemorrhage, perforation and dysfunction of the prosthesis. Recently, self -expand- able metal prosthesis have also been utilized for malignant esophageal stenosis, and palliation of this modality seems to be more effective than other modalities. However the main problems with these metal stents are tumor ingrowth leading to reobstruction, migration, and eophageal trauma by the distal, hard skirt of the stent. EsophaCoil stent is a simple coil with close loops made from a single flat wire of nickel titanium alloy. The radial force of this material is much stronger than stainless steel, expansion time is faster and the stent is able to dilate even extremely resistant strictures. This new metalic stent seems to have several advantages over the current commnerically available ones. We report our experiences with this EsophaCoil stent and review of literature.
