For relieving malignant esophageal strictures especially in the middle and lower part of the esophagus, consider the unique delivery system that FerX-ELLA Esophageal Stent - BOUBELLA brings. We suggest you get the optional anti-reflux valve to prevent gastric juices reflux especially if the stent is deployed in the lower part of the esophagus close to the cardia. Implantation of the stent over-the-wire can be performed under fluoroscopic guidance. The indications include : palliation of malignant esophageal strictures if a standard surgery is contraindicated, treatment of benign esophageal strictures which are refractory to standard therapy, and treatment of esophagorespiratory fistulas while contraindications are malign or benign strictures in the upper part of esophagus close to the cricopharyngeal muscle. Other features of the system are its excellent radial force, outstanding radiopacity and acid-resistant retrieval loop.
