Celiac Plexus Block and Neurolysis: A Review.

Pain is often associated with chronic pancreatitis and pancreatic cancer. Often times opioids are used to treat pain; however, the use of opioids is frequently difficult. Endoscopic ultrasound-guided celiac plexus block and celiac plexus nuerolysis are safe and effective modalities used to alleviate pain. Celiac plexus block is a transient interruption of the plexus by local anesthetic, while celiac plexus neurolysis is prolonged interruption of the transmission of pain from the celiac plexus using chemical ablation. Celiac plexus block is generally performed in the unilateral position, while celiac plexus neurolysis is performed in the unilateral or bilateral position.
