Duodenal ulcer (DU) is a common condition characterized by the presence of a well-demarcated break in the mucosa that may extend into the muscularis propria of the duodenum. More than 95% of DUs are found in the first part of the duodenum; most are less than 1 cm in diameter.

Pathophysiology: The duodenal mucosa resists damage from the effect of aggressive factors, such as gastric acid and the proteolytic enzyme pepsin, with the help of several protective factors such as a mucous layer, bicarbonate secretion, and protective prostaglandins.

Multiple Ulcers of the duodenal bulb.
Duodenal ulcer (DU) is a common condition characterized by the presence of a well-demarcated break in the mucosa that may extend into the muscularis propria of the duodenum. More than 95% of DUs are found in the first part of the duodenum; most are less than 1 cm in diameter Causes: The understanding of the etiology of DU has changed dramatically in the latter part of the 20th century. Historically, DU was thought to be a disease related to diet and environmental stress alone. Subsequent studies revealed the importance of pepsin and acid secretion in the pathogenesis of DU. The most revolutionary change in the knowledge of DU was the discovery in 1982 that the bacterium H pylori was present in most patients with DU.

Duodenal Ulcer and Pseudo Diverticulae.
H pylori
- H pylori are small, microaerophilic, spiral-shaped, gram-negative rods. The presence of H pylori in the stomach and duodenum probably is the most common bacterial infection in the world. H pylori infection is generally regarded as the most important etiologic factor in the development of DU. Most authors regard H pylori as the cause of 85-95% of DUs.
- H pylori can be cultured from up to 95% of DUs. Moreover, areas with a higher prevalence of H pylori infection have a higher incidence of DU. Several mechanisms exist by which the bacterium can induce duodenal mucosal damage. All evidence supports the assertion that H pylori is the major cause of DU. However, the risk of developing a DU in an individual infected with H pylori is only about 1% per year, and only 10-15% of individuals with H pylori infection develop a DU at any point in life. Therefore, other pathogenic factors must function either independently or in concert with H pylori to produce DUs.

Brunner Gland Hyperplasia.
Brunner gland hyperplasia in the duodenal bulb with associated giardia lamblia infection. Giardia lamblia is prevalent throughout the world. In the developing countries the prevalence rates are high. These organism infects the small intestine and may cause acute diarrhea. Frequently there is sudden of explosive, watery, foul-smelling diarrhea accompanied by abdominal distention and flatulence or chronic malabsorption, abdominal pain or any class of dyspepsia.

After suction of the blood, the image becomes more clearly. The ulcer is seen with some blood inside. Endoscopic treatment of an exposed or visible vessel in a large, deeply penetrating, posterior duodenal bulb ulcer may cause significant bleeding if a large serosal artery, the gastroduodenal artery, is involved.

Successfully injected, bleeding did not recur. The control of upper gastrointestinal bleeding is one of the fields in therapeutic endoscopy. It is critical that the endoscopist determine whether an ulcer is in the anterior or posterior wall. To inject a vasodestructive solucion (alcohol) is intended to destroy a bleeding vessel.

Lymphocytic Duodenitis.
This is a type of Duodenitis. with dense infiltration of the surface and foveolar epithelium by T lymphocytes, and associated chronic infiltrates are in the lamina propria Because of similar histopathology relative to celiac disease, lymphocytic gastritis has been proposed to result from intraluminal antigens. High anti–H pylori antibody titers have been found in patients with lymphocytic duodenitis and, in limited studies, the inflammation disappeared after H pylori eradication. However, many patients with lymphocytic gastritis are serologically negative for H pylori. A number of cases may develop secondary to intolerance to gluten and drugs such as ticlopidine.
