Diverticula are saclike mucosal pouches that protrude from a tubular structure.

True diverticula of the GI tract contain all layers of the GI wall. Esophageal diverticula and Meckel diverticula are true diverticula.

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.

Diverticular disease is characterized as symptomatic diverticulosis.

Diverticulitis is inflammation and/or infection of a diverticulum.
