Diverticule




Définition

Dilatation ou hernies sacciformes dans la muqueuse du côlon.

Physiopathologie

Pression intracavitaire causée par un déficit en fibre qui ralenti le transit intestinal qui
accroît l’absorption d’eau dans les selles qui se durcissent et se déplacent donc plus
difficilement dans l’intestin. La lumière de l’intestin diminue et augmente la pression
intracavitaire et favorise la formation de diverticules.

Étiologie

pressions intracavitaires élevées.

Facteurs de risque

Vieillesse
Alimentation pauvre en fibre et riche en glucides raffinées (pâtisseries par
exemple)
Troubles hydroélectrolytiques
Constipation et selles dures
