An oesophageal stent is a flexible mesh tube that is placed through the constricted area of your oesophagus (food tube) to allow food and beverages to pass from your mouth to your stomach for digestion and absorption of nutrients. Constrictions of the oesophagus are often caused by a tumour or radiotherapy treatment. The stent is inserted down the oesophagus and through the blockage, where it expands to open up the passage. The stent may only need to stay in a short time or, depending on the reason it may need to stay in permanently. If a biodegradable stent is used, this will usually dissolve in approximately 3-4 months.
