A celiac plexus block targets the group of nerve fibers that surround the main artery in your abdomen. These fibers come from your liver, stomach, pancreas, and part of your bowels, and they carry pain information to the brain. The block procedure injects a numbing medication into the fibers in order the interrupt the pain signals.
What conditions does it treat?
A celiac plexus block is useful for relieving abdominal pain caused by tumors and controls pain caused by the spread of cancer. To make sure that you experience pain relief, a diagnostic block made up of only anesthetic will be used first. If you experience pain relief, then the actual injection will be done.
What can I expect afterward?
You will feel some discomfort for the first few days at the injection site. The pain relief that you feel from the anesthetic will be immediate, but will wear off after several hours. The actual injection leaves you with pain relief for a few months. If the block works well for you, your doctor might recommend repeat injections. The pain relief lasts longer after each subsequent injection.
