Application progress of stent placement in esophageal malignant and benign stenosis

Stent placement is widely used for palliation of dysphagia caused by advanced esophageal carcinoma. As the development of technology, many new stents are being used for clinical therapy. Some stents are added with anti-reflux valve or retrievable device, some are loaded with ¹²⁵I; the biodegradable stent are even invented. Improvement of sents can decrease many complications while elevate survival rates. Several nonsurgical palliative modalities including endoluminal laser therapy, photodynamic therapy, electrocoagulation and brachytherapy are available to recanalize malignant stenosis, but the fastest palliative method is stent placement. Reports about treating benign esophageal stricture with stents are increasing, and temporary and biodegradable stents have a better effect.
