Résumé
Les explorations électrophysiologiques périnéales peuvent être utiles dans l’évaluation des constipations terminales. En effet, ces dernières, souvent secondaires à un anisme, peuvent déterminer une dénervation du plancher pelvien, en raison d’une neuropathie pudendale d’étirement. Cette neuropathie peut déterminer sur le long terme une incontinence fécale. L’électromyographie de détection des muscles périnéaux, l’analyse des latences sacrées et des latences motrices terminales des nerfs pudendaux sont les tests principaux mettant en évidence de telles neuropathies.
Abstract
Perineal electrophysiologic testing may be useful in case of a distal constipation. Indeed, distal constipation, frequently due to anismus, can lead to a pelvic floor denervation, often secondary to a stretch pudendal neuropathy. This neuropathy can induce faecal incontinence in the long term. Electromyographic investigations of the perineal muscles, sacral latencies and pudendal nerve terminal motor latencies are the main tests which demonstrate such neuropathy.
