This procedure is performed to diagnose and reduce abdominal pain caused by conditions such as cancer or pancreatitis. An injection is used to block the nerves serving the abdomen. An intravenous (IV) line may be used to administer medication to relax the patient. After numbing the skin of the back with a local anesthetic, the physician slides one or two needles through the body to the celiac plexus nerves. The physician uses X‑ray or CT scan guidance to position the needles correctly. Before injecting medication, the physician may inject a dye solution to confirm that the needles are correctly positioned. Anesthetic medicine is injected around the nerves to block pain signals from reaching the brain. The initial injection may be a test injection. If pain relief follows, a permanent block injection may be administered. The needles are removed. Many patients feel immediate pain relief from this procedure.
