Celiac Plexus Block

Overview

Celiac Plexus Block is a procedure used to treat chronic conditions such as chronic pancreatitis, chronic abdominal pain caused by cancer, and adhesions. It involves injecting local anesthetics into a group of nerves called the Celiac Plexus, which surrounds the aorta. These nerves not only control basic functions of the abdomen but also relay pain signals from organ tissues to the spinal cord and brain. The objective of the procedure is to block the transmission of pain signals from the celiac plexus to the brain, providing relief from chronic abdominal pain

Procedure

The Celiac Plexus Block procedure typically lasts between 10 to 30 minutes and involves the use of local anesthetics. To prolong the block’s duration, other medications such as epinephrine, clonidine, or steroids may be used. Like any procedure involving injections, some pain may be experienced during needle insertion. Local anesthetics are used to numb the skin and underlying tissues to reduce this pain. In some cases, patients may also receive IV sedation to make the procedure more comfortable. It’s important to note that due to possible amnesia from the sedation, patients may not remember parts or all of the procedure.

During a Celiac Plexus Block procedure, patients are typically positioned lying on their stomachs. Monitoring devices such as an EKG, blood pressure cuff, and oxygen-monitoring machines are used to monitor their condition throughout the procedure.

The skin is numbed at the injection site, and the area is sterilized with an antiseptic solution. Using an x-ray guidance machine, the needle is inserted just outside of the spine. A dye-like material is injected to ensure that the medication spreads to the appropriate area. The injection is then administered over a few minutes.

What to expect afterwards:

After a Celiac Plexus Block procedure, patients may experience reduced pain and possible weakness and numbness in the abdomen or leg. However, it’s important to note that these sensations are not the intended result of the block.

Patients can usually return to work the day after the procedure and may experience some soreness in the back where the injection was administered. While the local anesthetic wears off after a few hours, the actual block may last longer, possibly for several hours or even days.

If there is a positive response to the first injection, patients may be recommended for a series of further injections to provide longer-lasting relief.
