The colonic pseudo-obstruction pathogenesis is believed to be due to impairment of the autonomic nervous system. The autonomic impairment may involve the parasympathetic fibers of S2-S4 which is responsible for innervation of the distal colon and may lead to atonic colon and proximal obstruction. In few cases,<unk> 's syndrome (colonic pseudo-obstruction) may show atrophic myopathy with thinned colonic wall and intact myenteric plexus.
