Celiac Plexus Block

A celiac plexus block involves the injection of a local anesthetic into or around the celiac plexus of nerves that envelops the aorta, the primary artery in the abdomen. Normally, these nerves regulate essential nerve functions. However, in certain conditions, they can transmit pain signals from the gastrointestinal tract or abdominal organs to the spinal cord and brain.

What is the Purpose of a Celiac Plexus Block?

The purpose of a celiac plexus block is to block the celiac plexus nerves that innervate various organs and areas of the abdomen. By doing so, it may help alleviate abdominal pain. This procedure is commonly performed as part of the treatment for Chronic Pancreatitis and other forms of Chronic Abdominal Pain.

How Long Does the Celiac Plexus Block Take?

The actual injection typically takes between 10 to 30 minutes to complete.

What Is Administered During the Celiac Plexus Block?

The injection primarily consists of a local anesthetic. In some cases, epinephrine, clonidine, or a steroid medication may be added to extend the duration of the block’s effects.

Will the Celiac Plexus Block Cause Pain?

The procedure involves inserting a needle through the skin and deeper tissues, which can cause some discomfort. However, we may administer a local anesthetic using a very thin needle to numb the skin and deeper tissues before inserting the actual block needle. Additionally, most patients receive intravenous sedation to make the procedure more tolerable.

Will I Be Under General Anesthesia for the Celiac Plexus Block?

No, this procedure is performed under local anesthesia. Most patients also receive sedation to enhance comfort during the procedure. The level of sedation administered is based on each patient’s tolerance, and some may experience amnesia and not remember parts or all of the procedure.

How Is the Celiac Plexus Block Performed?

The patient lies on their stomach during the procedure. EKG, blood pressure, and oxygen-monitoring devices are used to monitor patients throughout the process. The celiac plexus block is conducted under sterile conditions.

The back’s skin is cleaned with an antiseptic solution, and a local anesthetic is used to numb the area. X-ray guidance is employed to position the needle(s) correctly along the outer aspect of the spine.

A test dose of dye is usually utilized to confirm the appropriate spread of the injected medication. Once confirmed, the injection is administered gradually over several minutes. The physician monitors the spread of the medication using X-ray imaging. When an adequate area is covered, the injection is complete. The needle is then removed, and a band-aid is applied.

What Can I Expect After the Celiac Plexus Block?

Immediately after the injection, you may experience warmth or a different sensation in the abdomen. Additionally, you may notice a reduction or absence of abdominal pain. Some patients may also experience temporary weakness or numbness in the abdominal wall or leg, although this is not the desired effect of a celiac plexus block.
