“…The phenomenon of colonic dilatation has aroused considerable interest and comment as to its aetiology. Some suggest that it is caused by hypokalaemia (Cohn, Copit and Turner, 1956), or the destruction of the autonomic nerve plexuses in the bowel wall (Bockus, Roth, Buchman, and Kalser, 1958), or smooth muscle toxic destruction (Walker and Curtis, 1965), although as Gallagher et al (1962) have pointed out, and in the present series this is confirmed, often the dilatation of the colon is most evident in areas that are not so grossly diseased, as in the right-sided colonic dilatation where there is advanced disease principally on the left side.…”
