Celiac plexus is a web of nerves that lies in the abdomen near the aorta, it consists of the nerves that innervate the abdominal contents from the lower esophagus to part of the colon. This pain may be caused by irritation, compression or entrapment of the nerve bundles because of tumor invasion, fibrosis, or chronic inflammation resulting from chronic pancreatitis or Crohn’s disease, among others. If unsuccessful by medication management a celiac plexus block can be done in which a long-acting local anesthetic is placed at the celiac plexus to block the transmission of pain from the abdomen.
