A celiac plexus block is a procedure performed to relieve severe abdominal pain by blocking the signals of nerves in the stomach, intestines, liver, pancreas, adrenal glands and other organs around the midsection. The injection will provide a dose of anesthetic to numb the area and produce immediate pain relief as well as a medication such as a corticosteroid or alcohol that will provide much longer-term respite from pain and related symptoms.
A celiac plexus block is generally conducted with the patient lying on his or her stomach. The skin surrounding the affected area will be cleaned. With the assistance of an X-ray and contrast dye, the needle is inserted. Once the needle is situated properly, the medicine is injected. The procedure typically lasts for 30 minutes. You will be monitored after the procedure is completed. The pain you have been experiencing should be reduced almost immediately, but the length of time it lasts varies from patient to patient
