Diverticulum

A diverticulum is a protrusion of the wall of a hollow organ (esophagus, bladder, intestine, less often than other hollow organs), congenital or formed in the weakened area from inside pressure (pulsion diverticulum) or contraction from the outside (traction diverticulum) (Fig.). At first, the small diverticulum is stretched by the contents (food, urine, etc.) that lingers in it, then turns into a bag that communicates with the lumen of the organ.

Overflowing, the diverticulum squeezes the organ, disrupting its function: for the esophagus diverticulum (see) - swallowing, for the urinary bladder diverticulum (see) - urination, etc. ulceration, perforation of the wall of the diverticulum, infection of the cavity of the diverticulum or surrounding tissues.
