This paper discusses the generic view of defaecation and examines the mechanisms contributing to constipation. Although it is recognised that there are specific causes that will require medical intervention, for the purpose of this paper only the general clinical management will be addressed.
A case of craniopagus parasiticus is described in which the parasitic twin is more fully developed anatomically than in any of the previous reports. Somatic and placental vascular anastomoses between the twins and hypoplasia of the umbilical cord of the parasite were also observed. These findings support the hypothesis that craniopagus parasiticus results from compromise of the blood supply to one of a pair of craniopagus conjoined twins.
