	Dr. Koop - Duodenal Diverticula- Health Encyclopedia and Reference
		Duodenal Diverticula are bulging pouch-like herniations (diverticula) in the wall of the duodenum (part of the small intestine).
		Duodenal diverticula are acquired outpouchings of the mucosa and submucosa, 90 percent of which are on the medial aspect of the duodenum.
		Diverticula are not seen in the first portion of the duodenum, where diverticular configurations are due to scarring by peptic ulceration or cholecystitis (inflammation of the gall bladder).

	► Duodenal atresia
		Duodenal atresia is a condition in which the duodenum (the first part of the small bowel) has not developed properly.
		The cause of duodenal atresia is unknown but it is thought that damage to the duodenum from a loss of blood supply during gestation causes the duodenum to narrow and become obstructed.
		Suggestion of duodenal atresia may be seen on routine ultrasound studies of the fetus.

		Duodenal stenosis is an example of an incomplete intrinsic abnormality; however, duodenal extrinsic stenosis can occur in association with malrotation or a preduodenal portal vein.
		Duodenal atresia is not usually regarded as a familial condition despite isolated reports of this condition in multiple siblings.
		Duodenal atresia differs from other atresias of the small and large bowel, which are isolated anomalies likely caused by mesenteric vascular accidents during later stages of development.

		The latter view is suggested by the stable incidence of perforations during this same period, and by the increase in the incidence of duodenitis and esophagitis as the incidence of duodenal ulcer has reportedly declined.
		Many patients with acute duodenal ulcer do not manifest the classic symptoms of the disorder: periodic epigastric pain or discomfort which is alleviated by food intake and/or use of antacids.
		Individuals with suspected duodenal ulcer who report significant weight loss should be investigated further for carcinoma of the stomach, gastric ulcer, or obstructing duodenal ulcer.

	Duodenal Switch - About Duodenal Switch
		The Duodenal Switch procedure (also called vertical gastrectomy with duodenal switch, biliopancreatic diversion with duodenal switch, DS or BPD-DS) is performed by approximately 50 surgeons worldwide.
		It generates weight loss by restricting the amount of food that can be eaten (removal of stomach or vertical gastrectomy) and by limiting the amount of food (specifically fat) that is absorbed into the body (intestinal bypass or duodenal switch).
		Malabsorption (Duodenal Switch): The intestines are divided and rearranged to separate food from the digestive juices, thereby creating malabsorption.

	Stomach and Duodenal Ulcers (Peptic Ulcers) (Site not responding. Last check: 2007-10-16)
		An ulcer is an open sore, or lesion, usually found on the skin or mucous membrane areas of the body.
		Today, research shows that most ulcers (80 percent of gastric ulcers and 90 percent of duodenal ulcers) develop as a result of infection with a bacterium called Helicobacter pylori (H. pylori).
		It is believed that, although all three of these factors - lifestyle, acid and pepsin and H. pylori - play a role in ulcer development, H. pylori is considered to be the primary cause in most cases.
