Celiac plexus neurolysis (guided by imaging/contrast study)
This procedure involves the use of imaging guidance to deliver a local anesthetic or sclerosing agent directly to the celiac plexus nerves, which may help manage chronic pain conditions like abdominal or back pain.

What Is the Purpose of This Procedure?
The celiac plexus is a network of nerves located near the abdomen that can send pain signals to the upper body. If you experience persistent pain (e.g., from conditions like pancreatitis, cancer-related pain, or chronic abdominal discomfort), this procedure may be recommended to block or reduce nerve signals. It’s typically performed under imaging guidance (like fluoroscopy or CT scan) to ensure accuracy and minimize risks.
How Is the Procedure Performed?
You’ll likely receive sedation or anesthesia to stay comfortable during the procedure. A needle or catheter is inserted under imaging guidance into the celiac plexus area. A contrast dye or anesthetic may be injected to confirm placement. Rarely, a sclerosing agent (to permanently damage nerves) may be used. The procedure usually takes 30–90 minutes and is done in a hospital or imaging center.
Recovery and Risks
Recovery varies: some patients feel pain relief within days, while others may need weeks. Mild side effects (e.g., bruising, temporary numbness) are common but usually resolve quickly. Rare risks include nerve damage, infection, or allergic reactions to contrast dye. Follow your doctor’s post-procedure care instructions.
When Might This Procedure Be Recommended?
This procedure is often considered for patients with chronic abdominal or back pain linked to nerve-related causes (e.g., after surgery, cancer treatment, or idiopathic pain). It’s not a cure but may provide temporary or long-term relief for specific pain patterns.
