A critical literature review allows an analysis on chronic constipation evaluation and on the association with anatomical or functional pelvic perineal disorders, the link with a pudendal neuropathy being frequent. The dyschezia clinical diagnosis must be completed by X-ray and manometric examinations to well determine the respective part of anatomical and/or functional disturbances. ⋯ The diagnosis must be made with a complete electrophysiological assessment and not only with the pudendal nerve latency terminal motor latency measurement. These pelvic-perineal disorders have plurifactorial aetiologies, they are linked together without univoqual chronology, each one may be the cause or the consequence of the other, and self-worsening evolution may occur.
