Ulcer niche
Introduction
Introduction Ulceration is a direct sign of stomach and duodenal ulcers. Gastric, duodenal ulcer (hepatitis ulcer, duodenal ulcer) is a common disease, which occurs in 20-50 years old. The incidence of duodenal ulcers is about five times that of gastric ulcers. More common in small bends, the tangent position is papillary, tapered or other shape, the edges are smooth and uniform, and the density is uniform. The bottom is flat or slightly uneven.
Cause
Cause
Gastric ulcer and duodenal ulcer are both peptic ulcers. Because of their common epidemiology, pathogenesis and clinical manifestations, they are generally referred to as peptic ulcers. But after all, it is two independent diseases, each with its own characteristics in terms of clinical manifestations, and it is necessary to identify them.
(1) Age of onset: Generally, duodenal ulcers occur in young and middle-aged people, while gastric ulcers occur at a later age, mostly in middle-aged and young adults. Clinical duodenal ulcers are significantly more than gastric ulcers, the ratio of the two is about 3:1, mostly male.
(2) Clinical symptoms: Gastric and duodenal ulcers can have regular upper abdominal pain. Gastric ulcers can cause pain in 1/2 to 1 hour after a meal, and disappear spontaneously before the next meal. Some cases can cause abdominal pain after eating, especially the pyloric canal ulcer is more obvious, often accompanied by postprandial fullness discomfort. Or nausea and vomiting. Duodenal ulcer pain often occurs 1 to 3 hours after a meal, and the pain is relieved after the next meal. About half of the patients had midnight pain.
(3) Signs: During the onset of gastric ulcer, the patient has a fixed and limited tenderness point to the left under the xiphoid process. The tender point of duodenal ulcer was mostly right under the xiphoid process, and there was no obvious positive sign when remission.
(4) analysis of gastric juice: gastric acid secretion in patients with gastric ulcer is normal or slightly lower than normal; duodenal ulcer is often too high in gastric acid secretion.
(5) Prognosis: a small number of patients with gastric ulcer can develop cancer. If there is a history of chronic gastric ulcer, if the age is over 45 years old, the symptoms are stubborn and the strict 8 weeks medical treatment is invalid, and the fecal occult blood continues to be positive, the cancer may be considered. Should be highly vigilant and further inspection. Duodenal ulcers do not develop cancer.
If you are not diagnosed, you can make a gastrointestinal dialysis or gastroscopy to confirm the diagnosis early.

Ulcer disease belongs to the categories of "stomach cramps", "liver stomach pain", "heartache", "swallowing acid" and so on. The folks are often referred to as "heartache", "stomach pain", "stomach pain", "hunger and hunger".
Ulcer disease is characterized by recurrent rhythmic upper abdominal pain, often accompanied by feelings of heating, acid reflux, burning, noisy, and even nausea, vomiting, hematemesis, and blood in the stool. There are round, oval chronic ulcers in the gastrointestinal area.
1. Shadow is a direct sign of ulcer disease. The tangential position, which is protruding from the contour of the inner wall of the stomach, is papillary or semi-circular; in the positive position, the shadow is circular or elliptical, and the edges are smooth and tidy.
2. The mucosa around the shadow: the tangential position, the transparent thin line shadow of 1~2mm is displayed at the junction of the shadow and the stomach, which is found on the upper edge or the lower edge of the shadow, or the entire edge of the shadow.
3. "Narrow neck sign": the tangential position, the mouth of the mouth and the stomach cavity has a diameter of about 0.5 ~ 1cm narrower than the shadow, called the "neck sign".
4. "Coat sign": There is a thin and thin line density reduction area at the mouth of the shadow, such as the collar worn by the neck.
5. "Day halo sign" around the shadow: the position, the wide and narrow inconsistent translucent band around the shadow, the edge is smooth.
6. The mucosal folds centered on the shadow are gathered; they are distributed radially, and the periphery is gradually thinned and disappeared, which is another sign of chronic ulcer.
