It is at the level of T12 and L, veebrae anterior to the crura of the diaphragm. It contains visceral afferent and efferent fibers divided from T5 to T1, by means of greater, lesser and least splanchnic nerves. Celiac plexus innervates most of the abdominal viscera, therefore this procedure blocks the nerves which come from the pancreas, liver, gall bladder, stomach, intestine, spleen, kidney and adrenal glands. A celiac plexus block can be combined with an intercostal block to provide anesthesia for intra-abdominal surgery.

Celiac plexus block can be done by following three approaches : - Retrocrural (classic) approach, anterocrural approach and splanchnic nerve block. Celiac plexus block is given to treat intractable pain in chronic pancreatitis, gastric & pancreatic malignancies. It can be combined with an intercostal block to provide anesthesia for intra-abdomival surgery.
