16853 Celiac Plexus Block

Overview

A celiac plexus block is a pain-relief procedure. The celiac plexus is a group of nerves near the spine and upper belly that carries pain signals from organs such as the pancreas, stomach, liver, and bowel. A specialist uses a thin needle, usually guided by imaging, to inject medicine near these nerves. The medicine can quiet or block pain signals for a time. It does not treat the cause of the pain.

It is not an everyday procedure. It is a specialist option for selected people with severe upper belly pain, often from pancreatic cancer or long-term pancreatitis.

It is mostly considered for adults with severe pain from pancreatic cancer or chronic pancreatitis. It is used rarely in children, and only by specialist teams.

Symptoms

Common symptoms

• Severe pain in the upper belly that may spread to the back
• Pain from pancreatic cancer or chronic pancreatitis (long-term inflammation of the pancreas)
• Pain that has not eased enough with other pain care
• Pain that makes eating, sleeping, or daily life hard

Symptoms in children

• The procedure is rarely used in children. Specialist teams decide if it is safe and may help.

Symptoms in older adults

• It is more often considered for older adults with long-term pancreatitis or cancer-related pain. The care team checks overall health and medicines that affect bleeding.

Causes

Main causes

• Cancer in the pancreas or other upper belly organs
• Chronic pancreatitis, which is long-term inflammation of the pancreas
• Other long-term upper belly pain conditions chosen by a specialist pain team

Risk factors

• Advanced cancer in the upper belly
• Long-term pancreatitis
• Severe pain that has lasted a long time
• Health problems that affect blood pressure or bleeding
• Medicines that affect bleeding; your care team will review these

When to see a doctor

See a doctor urgently if:

• Fever, spreading redness, or pus at the needle site
• Worsening belly or back pain after the procedure
• Dizziness, fainting, or feeling very weak
• New leg numbness or weakness
• Vomiting that will not stop or trouble passing urine

Book a routine appointment if:

• Before the procedure, if you have questions about benefits, risks, or what to expect
• If your pain is not controlled after the procedure
• If you need to change your appointment or have new health changes
• If you feel anxious or worried about the procedure

Diagnosis

There is no single test that diagnoses a need for a celiac plexus block. Your doctor and a pain specialist review your pain, health history, and test results to decide whether this procedure is safe and may help.

Tests that may be done

• Review of your pain and medical history
• Physical exam
• Imaging such as CT, MRI, or ultrasound
• Blood tests to check safety
• Sometimes a short test block to see if it helps

What to expect at your appointment

You may be asked not to eat for a few hours before the procedure. Arrange for someone to take you home. The procedure often takes about 30 to 60 minutes, and you are watched afterward before you leave.

Treatment

A celiac plexus block is one part of pain care. It may be combined with treating the underlying condition, physical therapy, emotional support, and other pain approaches. Relief can last weeks to months, and the procedure can sometimes be repeated.

Self-care at home

• Follow your care team's instructions about eating and drinking before the procedure
• Rest and avoid heavy lifting for a day, or as advised
• Keep the needle site clean and dry
• Drink fluids and eat gently as you feel able
• Write down your pain levels and any side effects
• Do not drive until your care team says it is safe

Medical treatments

A pain specialist cleans the skin, numbs it, and guides a thin needle near the celiac plexus using imaging. A numbing and blocking medicine is injected. You may feel pressure or a brief sting. The team watches your blood pressure and how you feel. Most people go home the same day after observation.

When is surgery considered?

A celiac plexus block is not surgery. It is usually an outpatient needle procedure. Surgery may be considered only for the underlying condition, not for the block itself.

Living with this condition

Keep a simple pain diary and plan activities around your energy. Some people need small, frequent meals if nausea or pain affects eating. Follow up with your pain team to review how well the block worked.

Lifestyle tips

• Gentle walking and light activity can help you feel steadier
• Avoid heavy lifting for a day, or as your team advises
• Follow advice about alcohol and diet from your care team
• Get regular sleep and rest when needed
• Ask for help with chores or travel on procedure day

Diet and exercise

Eat regular, balanced meals. If you have pancreatitis, follow any diet plan from your specialist. Gentle movement, such as short walks, is usually helpful. Ask your team before starting harder exercise.

Mental health and emotional wellbeing

Long-term pain and medical procedures can cause worry, low mood, or feeling alone. These feelings are common. Talk with your care team. If you have thoughts of harming yourself, contact your local emergency services or a crisis support service right away.

Prevention

You cannot prevent the need for a celiac plexus block, because it is a chosen pain treatment. You can lower the chance of problems by following your care team's instructions before and after the procedure.

Vaccines

Vaccines are not part of this procedure. Keep routine vaccines up to date as advised by your healthcare provider.

Screening programmes

There is no screening test for needing a celiac plexus block. A specialist assesses whether it is safe and suitable based on your pain, health, and imaging.

Complications

If left untreated

• Severe pain may continue and affect sleep, eating, mood, and daily life
• The underlying condition may progress
• Less activity can lead to weakness and loss of stamina

Long-term outlook

Many people get useful pain relief from a celiac plexus block, but it is not permanent and works differently for each person. Your care team can adjust your pain plan over time. Ask questions and keep them updated on how you feel.
