What is a Celiac Plexus Block?
The celiac plexus is a bundle of nerves located in your upper abdomen, behind the stomach near the celiac artery and the abdominal aorta. It connects nerves from the liver, pancreas, gallbladder, stomach, spleen, and kidneys to your brain and spinal cord. When pain occurs in one of these organs, often due to a tumor or other damage, a celiac plexus block can help relieve that pain. A celiac plexus block is an injection that delivers pain medication as well as a medication that destroys or damages the nerves for longer-lasting pain relief. The procedure is a low-risk, non-surgical treatment that, if successful the first time, will most likely continue to provide pain relief with repeated treatmentsWhy is a Celiac Plexus Block performed?
Celiac plexus blocks are a minimally invasive treatment option that can relieve severe pain for many people, allowing many to resume their normal daily activities. Celiac plexus blocks are commonly used to relieve upper abdominal pain, including pain related to:- Metastatic cancer in the abdomen
- Chronic pancreatitis
- Liver tumors
- Cancer pain that is intractable and has been unresponsive to most pain treatments. For patients with pain that is unresponsive to other treatments, or who suffer from serious side effects from cancer treatments, celiac plexus blocks reduce pain and can increase your overall quality of life.
How is a Celiac Plexus Block performed?
For the procedure itself, you lie flat on your belly on an examination table. Your doctor will apply a topical anesthetic to numb the area. Sometimes your doctor may recommend intravenous sedation to make the procedure more comfortable. Using X-ray guidance, your doctor inserts a thin needle next to your spine. When the tip is in the correct position, a second needle is placed on the opposite side of the vertebrae. Contrast dye and local anesthetic are injected. If the needle and the block are properly administered, you will experience nearly instantaneous and profound pain relief. Your doctor may also inject another medication that destroys the celiac nerves for longer-lasting pain relief. The entire procedure usually takes less than 30 minutes. Your physician will monitor your pain and vital signs (pulse, blood pressure, temperature) after the procedure. For many patients experiencing severe abdominal pain, Celiac plexus blocks are an appropriate non-surgical, low risk treatment. As with any procedure, there can be side effects. Most of these are due to misplacement of the needle and could include the following:- Bleeding
- Infection
- Collapsed lung (pneumothorax)
- Puncture of surrounding organs
- Puncture of adjacent vessels
- Drug allergy
- Nerve damage
- Paralysis
