Résumé
Le syndrome de l’ulcère solitaire du rectum (SUSR) est une affection bénigne de la muqueuse rectale. Cliniquement, dyschésie et saignements sont les signes les plus fréquents. Endoscopiquement, l’aspect est très polymorphe: ulcère, érythème ou pseudotumeur. L’histologie est indispensable au diagnostic, retrouvant dystrophie glandulaire et présence de fibres musculaires dans le chorion. Le mécanisme des lésions serait ischémique par traumatisme d’un trouble de la statique rectale sur un obstacle fonctionnel à la défécation.
Abstract
Solitary rectal ulcer syndrome is a benign abnormality of the rectal mucosa. The commonest clinical features are dyschezia and bleeding. Endoscopic appearances are very variable: ulcer, erythema or pseudo-tumour. Histology is essential for the diagnosis. There is glandular dystrophy and muscle fibres are found in the lamina propria. The cause of the lesions might be ischaemia due to trauma resulting from rectal stasis associated with dysfunctional defecation.
