A celiac block is an injection of pain medication that will help relieve abdominal pain, commonly due to cancer or chronic pancreatitis.
The celiac plexus is a group of nerves that surrounds the main artery into your abdomen known as the aorta. Blocking these nerves from carrying pain information can help you stop feeling pain in your abdomen.
A celiac block is indicated in pain involving the pancreas, liver, and stomach. This injection is sometimes performed with a CT-scan, but is more commonly done with the help of x-rays. It is widely used in the treatment of pancreatitis and pancreatic cancer.
Initially, the procedure is performed with local anesthetic, such as lidocaine or marcaine. If it is successful, then a solution may be injected to stop the celiac nerves from causing pain. This procedure is also known as a lytic block. Typically, the procedure takes less than 30 minutes and you can go home the same day.
