A 50-year-old man with pancreatic cancer is experiencing intractable abdominal pain. He elects to have a diagnostic celiac plexus block. Which of the following is most likely to occur after the block?
Currently, the primary indication for a celiac plexus block is for the treatment of pain due to intraabdominal malignancies. Celiac plexus block is a loosely used term that implies blockade of the celiac plexus or the splanchnic nerves. The celiac plexus is located inferior to the diaphragm, posterior to the stomach, and lies just anterior to the aorta at the level of the L1–2 vertebral bodies. It is the largest prevertebral plexus and contains postganglionic cell bodies of sympathetic efferents that synapse with preganglionic sympathetic efferents with cell bodies originating from T5 to T12. The celiac plexus also contains sensory afferents from the following abdominal viscera: pancreas, stomach, liver, biliary tract, spleen, kidneys, adrenals, omentum, small bowel, and large intestine (to the splenic flexure).
