Duodenal stricture
Introduction
Introduction The lateral wall of the duodenum is caused by sacral contraction or scar formation due to post-balloon ulceration, resulting in narrowing of the lumen and eccentricity.
Cause
Cause
The protective mechanism of the gastric duodenal mucosa of normal people is sufficient to resist the erosion of gastric acid and pepsin. However, when certain factors impair a certain part of the protective mechanism, gastric acid and protease may erode the mucosa and cause ulcer formation. Excessive gastric acid secretion far exceeds the defense and repair of the mucosa and may also cause ulceration. Recent studies have shown that Helicobacter pylori and non-steroidal anti-inflammatory drugs are the most common cause of ulcer damage caused by gastrointestinal protective mechanisms, and gastric acid plays a key role in ulcer formation. In addition, drugs, stress, hormones can also lead to the emergence of ulcers, a variety of psychological factors and poor eating habits can induce the emergence of ulcers.

Diagnosis
Differential diagnosis
Duodenal stenosis should be identified as being caused by tuberculosis or by ulcers.
Duodenal tuberculosis is a rare disease. Duodenal obstruction is the most common type of duodenal tuberculosis, mainly showing abdominal pain and vomiting. Mostly after eating, there is a feeling of fullness or pain in the upper abdomen, nausea, vomiting, and pain in the upper abdomen or a feeling of fullness after vomiting.
Duodenal ulcer is a common disease of the digestive tract. It is generally believed that the cerebral cortex is exposed to external irritations, causing sputum in the blood vessels and muscles of the stomach and duodenum, causing dystrophic dysfunction and gastrointestinal gastrointestinal cells. The resistance of the mucosa is reduced, causing the gastrointestinal mucosa to be easily digested by gastric juice to form an ulcer.
