- Cancer in the food pipe (oesophagus) can partly or completely cause a blockage and make it difficult to swallow.
- The oesophagus can also get narrower after treatment such as surgery or radiotherapy. In addition to this nutritional intake can be limited and interventional radiology can provide a number of treatment options.
- Cancer within the oesophagus can limit food intake, a metal stent can open the oesophagus improving oral intake and nutrition.
- The stent is inserted under X-ray guidance. A fine wire down into the oesophagus until it reaches the blockage. Images are then taken to deline the blockage. A stent is passed down the wire until it is in the right position. The stent is then deployed and the position confirmed with an X-ray.
- X-ray dye is then instilled to ensure the blockage has opened.
- The oesophagus can become narrow after radiotherapy or surgery. This can again limit food intake and an oesophageal dilation can be performed to open the oesophagus.
- This procedure is performed under X-ray guidance with the passage of a fine wire through the blockage, similar process to a stent insertion. Once the position of the blockage is confirmed a balloon is passed and the narrowing is opened.
- Dye is then passed down a tube to assess the blockage ensuring success of the procedure.
Biodegradable stent insertion
- An alternative to balloon dilation is the insertion of a biodegradable stent. This is inserted in the same way as a metal stent however, the stent dissolves over a period of three months.
- The stent applied a consistent period of dilation which in selected cases will provide successful opening of the oesophageal narrowing.
- Maintaining enough nutrition may not always be possibly relying on oral intake alone. A feeding tube inserted directly into the stomach provides nutritional access sustaining calorific intake through chemo or radiotherapy regimes.
- The tube is inserted using X-ray guidance under sedation. Once the tube has been placed the position is confirmed using X-ray dye.
- Feeding can then commence through the tube increasing much needed nutritional intake.
- Similar to the oesophagusa tumour in the colon can cause a blockage or severe narrowing which, can result in bowel obstruction. This can be a serious complication and prompt treatment is paramount.
- With the aid of a flexible tube called and endoscopy passed through the rectum the position of the blockage is found. Once the position is confirmed using X-ray a fine wire is passed into position and a stent is deployed. This allows relief of the obstruction.
- This is a minimally invasive alternative to surgical treatment and allows immediate relief of the blockage without the risks associated with alternative surgical treatment.
