Successful block of the celiac plexus denervates the denervatives of the foregut and therefore can successfully interrupt nociceptive stimuli from the pancreas, stomach, liver, etc. Although permanent neurolytic block is much less successful for malignant chronic pancreatitis syndrome, it is specifically useful for treatment of intractable pain that often accompanies carcinoma of the pancreas or other upper abdominal visceral tumors. This was a case report in which intractable pain due to malignant gastric cancer was successfuly controlled by the permanent neurolytic celiac plexus block.
