Gastric erosion occurs when the mucous membrane lining the stomach becomes inflamed. Specifically, the term "erosion," in this context means damage that is limited to the mucosa (which consists of three distinct layers: The epithelium (in the case of a healthy stomach, this is non-ciliated simple columnar epithelium), basement membrane, and lamina propria).
The duodenal bulb is the site of duodenal ulcer occurrence. Duodenal ulcers are more common than gastric ulcers and - unlike gastric ulcers - are caused by increased gastric acid secretion. Duodenal ulcers are commonly located anteriorly, and rarely posteriorly. Anterior ulcers can be complicated by perforation, while the posterior ones bleed.
Cameron lesions. A long linear erosion and smaller non-linear erosions on the crests of inflamed gastric folds at the level of the diaphragm. The diaphragm separates the chest from the abdomen. The esophagus (swallowing tube) passes through the hiatal opening in the diaphragm to reach the stomach. With a hiatal hernia, part of the stomach is ...
Peptic ulcer disease is a break in the inner lining of the stomach, the first part of the small intestine, or sometimes the lower esophagus. [1] [7] An ulcer in the stomach is called a gastric ulcer, while one in the first part of the intestines is a duodenal ulcer. [1]
The first part of the duodenum is the most common location of ulcers since it is where the acidic chyme meets the duodenal mucosa before mixing with the alkaline secretions of the duodenum. [24] Duodenal ulcers may cause recurrent abdominal pain and dyspepsia, and are often investigated using a urea breath test to test for the bacteria, and ...
Duodenal causes: Duodenal ulcer; Vascular malformation, including aorto-enteric fistulae. Fistulae are usually secondary to prior vascular surgery and usually occur at the proximal anastomosis at the third or fourth portion of the duodenum where it is retroperitoneal and near the aorta. [5] [6] [7] Hematobilia, or bleeding from the biliary tree
Occasionally, there may be a large acute ulcer in the duodenum (Curling's ulcer). [4] Generally, there are multiple lesions located mainly in the stomach and occasionally in the duodenum. They range in depth from mere shedding of the superficial epithelium (erosion) to deeper lesions that involve the entire mucosal thickness (ulceration). [5]
Dieulafoy lesions are characterized by a single abnormally large blood vessel beneath the gastrointestinal mucosa that bleeds, [8] in the absence of any ulcer, erosion, or other abnormality in the mucosa. The size of these blood vessels varies from 1–5 mm (more than 10 times the normal diameter of mucosal capillaries).
