What is the success rate of using intestinal stents in cancer patients?

The success rate of using intestinal stents in cancer patients is generally high, especially for relieving malignant bowel obstructions. Here are some key points regarding their success:

1. **Technical Success**: This refers to the successful placement of the stent in the correct location within the intestine. Studies report that the technical success rate of intestinal stenting in cancer patients ranges from **90% to 95%**.

2. **Clinical Success**: Clinical success means that the stent effectively relieves symptoms and restores bowel function. For malignant bowel obstructions, the clinical success rate is reported to be between **70% and 90%**. This rate can vary based on factors such as the size and location of the tumor, the patient’s overall health, and the stage of the cancer.

3. **Complications**: While stents are effective, complications can occur in about **20% to 30%** of cases. Common complications include stent migration (movement), perforation of the bowel, or re-blockage due to tumor growth.

4. **Palliative Use**: Intestinal stents are often used as a palliative option for cancer patients with advanced-stage tumors, particularly when surgery is too risky. They help improve quality of life by reducing symptoms like pain, vomiting, and inability to eat.

Stents are widely considered effective and less invasive than surgery, providing relief from bowel obstructions in cancer patients with relatively high success rates.
