Definition of Diverticular Disease
Diverticula are saclike mucosal pouches that protrude from a tubular structure.
False or pseudo-diverticula are mucosal and submucosal protrusions through the muscular wall of the bowel. Colonic diverticula are pseudodiverticula.
A single pouch is called a diverticulum and ≥ 2 pouches are called diverticula. These terms are occasionally used incorrectly.
Diverticulosis is the presence of one or more diverticula.
Diverticulitis is inflammation and/or infection of a diverticulum.
