Diverticulum

Diverticula - sack-like protrusion of the mucous membrane and the submucosal layer into defects in the muscular membrane of the digestive tract. Diverticula are congenital (their wall consists of all layers of the intestine, they are located on the antiblasmic edge of the intestine) and acquired. Acquired diverticula arise due to inflammatory changes in the organ wall and surrounding tissues; Can be pulsed (in the base - increased pressure in the lumen of the organ with subsequent protrusion of the mucosa) and traction (inflammatory periprocesses draws in the organ wall).
