The CP carries afferent innervation of the upper abdominal viscera, from the distal esophagus and stomach to the mid-transverse colon, as well as the pancreas, kidneys, gall bladder, adrenals, and portions of the small bowel. CP blocks are indicated for the diagnosis and treatment of upper abdominal pain as it can be performed to help separate out visceral from somatic pains, and can be used as a treatment for chronic cancer–related pain as well as non-cancer-related pain. It is important to note that pain carried by somatic nerve fibers will not be affected when the CP is blocked.
