title: [Proposal for a radiologic classification of disorders of the pelvi-rectal angle based on measurement of the posterior rectal inclination. Value of dynamic digitalized rectography].
abstract: The difficulties for evaluation of the perineal descent have always been linked to the choice of references and mostly with the incertitude of the measurement of length on the radiographic film. This present study was carried out to evaluate the perineal descent on the choice of an angular measurement: the posterior rectal inclination. The dynamic digitalized rectography was used to investigate the pelvic floor status of 134 women: 115 patients complaining of idiopathic constipation, and 19 healthy volunteers. Results have shown 3 populations with an increasing graduation of perineal impairment and led to propose a radiologic classification of pelvic floor impairment: stage I, or solid perineum, stage II, or descending perineum and stage III or descended perineum. This study has brought up that the first sign of a pelvic floor abnormality may be increased descent during straining, only later followed by perineal descent at rest. The relationship linking abnormal perineal descent and excessive opening of the ano-rectal angle suggested logically that fecal incontinence may be the end complication of the Descending Perineum Syndrom.
