Stents and bypass surgery for pancreatic cancer
Pancreatic cancer can block the bile duct, causing jaundice. The bile duct is the tube that carries bile from the liver to the duodenum (first part of the small intestines). Bile is a fluid produced by the liver to help digestion. If it blocks the duodenum, it can cause sickness. You may have a stent put in or bypass surgery to relieve these symptoms.
If you have locally advanced or advanced pancreatic cancer it may not be possible to have surgery to remove the cancer. But you may be offered chemotherapy, and sometimes radiotherapy, to control the growth of the cancer and relieve symptoms. And there are treatments to relieve your symptoms.
Stents are small, flexible plastic or metal tubes that are inserted into your bile duct or duodenum to relieve the blockage. A stent used to open the bile duct is called a biliary stent. A stent used to open the duodenum is called a duodenal stent.
Having a stent put in is generally a simple procedure, and your symptoms should start to improve quickly. There can be a few problems with a stent. For example, it can get blocked, move out of place, and there is a risk of an infection. But there are ways to treat these problems.
Bypass surgery for a blocked bile duct is called a choledochojejunstomy. It involves cutting the bile duct above the blockage and attaching it to the small intestines. This bypasses the blockage. Bypass surgery for a blocked duodenum is called a gastro-jejunostomy, where the surgeon will connect the stomach to the small intestines.
You may have bypass surgery if you can’t have a stent, or if a stent hasn’t worked. Sometimes, it may be done if your surgeon started surgery to remove the pancreatic cancer, but found that it wasn’t possible to remove the cancer as it had spread beyond the pancreas.
Bypass surgery is a major operation, and it may take two to three months to recover.
It may take some time to build up your appetite after a stent or bypass surgery. Try starting with small amounts of food, and gradually increase the size of your meals. If you had a stent for a blocked duodenum, you will need to be careful what you eat to make sure the stent doesn’t get blocked. Read more about diet after a stent or bypass surgery.

There is support available to help you cope with pancreatic cancer. You can also speak to our specialist nurses on our free Support Line with any questions or concerns about having a stent inserted or bypass surgery.
