		Diverticula cause symptoms in only a minority of patients, but their presence should not be ignored in the differential diagnosis of acute abdominal events.
		The assumption is that extraluminal duodenal diverticula are rare in those under the age of 30, but may be present in up to 20 per cent of the general population with increasing age.
		Ninety per cent of duodenal diverticula are asymptomatic and are detected incidentally during radiological or endoscopic investigation of the upper gastrointestinal tract for an unrelated disease.

	DIVERTICULAR DISEASE OF THE COLON - Patients - American College of Gastroenterology
		While diverticula can be present anywhere in the entire digestive tract, they are most common on the left side of the large intestine, the area known as the descending and sigmoid colon (Figure 1).
		Diverticula as well as polyps and other growths can be seen with this instrument.
		Diverticulitis is an inflammation and/or infection of one of the diverticula.

	Diverticula Diverticulosis Diverticulitis (Site not responding. Last check: 2007-10-09)
		Diverticula occur throughout the gut, but by far the most common and most important are those that occur in the colon.
		The common hypothesis is that relatively high pressures generated within the colon by muscular contractions force the inner mucosa to penetrate through the path of small blood vessels within the colon wall and to bulge with the serosa beyond (Figure 1).
		If diverticula occur in one half of the elderly population and the IBS occurs in 15% of adults, it is not surprising that sometimes they may coexist.

		Diverticula usually occur in the large intestine and rarely in the stomach and small intestine.
		Diverticulosis is the presence of multiple diverticula (sac-like pouches in the wall of the intestine), usually in the large intestine.
		Diverticula may develop anywhere in the large intestine but are more common in the last part of the large intestine just before the rectum.

	What are diverticula?
		In most people with diverticula the intestinal muscle is normal in appearance and thickness, but in some people it becomes thicker than normal and it has an unusual structure when examined under the microscope.
		Diverticula are usually discovered when a problem such as rectal bleeding or abdominal pain is being investigated by X-ray (barium enema) or endoscopy (sigmoidoscopy or colonoscopy).
		As diverticula are so common among older people who are well, it is very important to be sure that they are the cause of the problem and not something else.

	eMedicine - Esophageal Diverticula : Article by Jack Bragg, DO, FACOI (Site not responding. Last check: 2007-10-09)
		Sometimes Zenker diverticula are called pharyngoesophageal diverticula because of their close proximity to the cervical esophagus; however, this is somewhat of a misnomer because the diverticula actually arise from the hypopharynx rather than from the esophagus.
		Zenker diverticula are believed to occur because of an outflow obstruction caused when loss of coordination of the buccal squirt (ie, swallowing movement of the tongue posteriorly with contraction of the oropharyngeal muscles) and opening of the cricopharyngeus (ie, the upper esophageal sphincter) occurs.
		Diverticula of the esophagus may be associated with motility disorders or structural disorders of the esophagus, such as strictures.

	Aren't disorders of motility observed whatever the etiology of these diverticula ? (Site not responding. Last check: 2007-10-09)
		Traction diverticula are likely to be true diverticula possessing a complete muscular layer, whereas pulsion diverticula are false diverticula due to protrusion of the mucosa and submucosa through the muscular layer.
		Traction diverticula of the acquired type are found in association with contracted fibrotic lymph glands and the scar tissue of chronic granulomatous inflammation, often tuberculous in origin.
		Belsey [1] has suggested that parabronchial diverticula unassociated with motility disorders or chronically infected lymph glands may be enterogenous cysts or foregut duplications which have established a communication with the esophageal lumen.

		Diverticular disease is an inflammation or infection in the pouches, known as diverticula, which are located in the colon.
		Physicians do not know what causes the infection that causes diverticulitis, but believe it may begin when stool or bacteria are caught in the diverticula.
		In the past, avoiding foods with small seeds, such as tomatoes or strawberries, was suggested because it was believed that particles could lodge in the diverticula and cause inflammation.

	What Is Diverticular Disease? (Site not responding. Last check: 2007-10-09)
		Diverticular disease is a condition in which small pouches, called diverticula, develop in the wall of the colon, or large intestine.
		In a small number of people who develop diverticula, the diverticula become inflamed or infected.
		In about 10 to 25 percent of the people who have diverticula (small pouches in the wall of the colon), the diverticula become inflamed and infected.

	Diverticulum - Wikipedia, the free encyclopedia
		A diverticulum (plural: diverticula) is medical term for an outpouching of a hollow (or a fluid filled) structure in the body.
		Its use implies that the structure is not normally present, although embryologically, some normal structures begin development as a diverticulum arising off of another structure (for example, the lungs begin as a diverticulum forming off of the ventral foregut).

		These sacs, called diverticula, occur with increasing frequency after the age of 40.
		Diverticula are thought to develop as a result of high pressure or abnormal pressure distribution within the colon.
		High pressure exerted against the colon wall causes pouches of the intestinal lining to bulge outwards through small defects in the colon wall.
