Antral

Introduction to antral sinusitis Antralgastritis (antrumgastrititis) refers to a chronic inflammation that is confined to the antrum of the stomach. The main lesions are mostly confined to the mucosa, but also to the muscular or serosal layer. In the lesion part, edema, inflammatory cell infiltration and fibrous tissue hyperplasia, local thickening, and even stenosis; in some cases, mucosal surface erosion and intestinal glandularization may change. Gastric sinusitis occurs mostly in men over the age of 30. basic knowledge The proportion of illness: 0.003% Susceptible people: no special people Mode of infection: non-infectious Complications: bloating, abdominal pain, nausea and vomiting

Cause of sinusitis

Cause of disease (30%):

When suffering from chronic stomach diseases and gastrointestinal diseases, the local defense function of the gastric mucosa is lowered, and gastric dysfunction occurs, and gastritis occurs. In addition, tonsillitis caused by tonsillitis, sinusitis, caries infection, etc., can often reduce the barrier function of the gastric mucosa and induce antral sinusitis.

Mental factors (10%):

Gastric sinusitis is closely related to mental factors, and when symptoms are fluctuating or fearful, the symptoms can be exacerbated. The parasympathetic nervous system is also prone to attack when excited. Some patients with antral sinusitis have symptoms of upper abdominal pain similar to duodenal ulcer

Alcohol and tobacco stimulation (20%):

Long-term smoking can also cause excessive secretion of gastric acid; refluxing bile into the stomach and destroying the gastric mucosa; alcohol can stimulate gastric acid secretion and directly damage the gastric mucosa.

Irregular diet (25%):

Overeating or irregular eating can affect the digestive function of the stomach, causing indigestion and malnutrition, and malnutrition can weaken the barrier function of the gastric mucosa.

Gastric sinusitis prevention

1, excessive stomach acid should avoid eating foods that stimulate gastric acid secretion, such as flavor spices, alcohol, sour agents.

2, should not eat too hot too spicy, too salty, overheated, too rough and irritating food, diet is regular, food should be rich in nutritious, digestible soft food, eat more plant protein, vitamins More food.

3, lack of stomach acid, avoid dilute gastric juice, diet should be added vinegar, lemon juice, acid seasonings, eat less difficult to digest, easy to flatulence food, eat and drink as much as possible after meals.

4, avoid tobacco and alcohol. After smoking, nicotine can stimulate the gastric mucosa to increase gastric acid secretion, causing harmful stimulation to the gastric mucosa, damage the gastric mucosa, and affect the blood supply of the gastric mucosa and the repair and regeneration of gastric mucosal cells.

5, avoid life irregular and overworked, pay attention to proper rest, exercise, physical exercise can promote gastrointestinal motility and emptying, so that gastrointestinal secretion function, digestive power, and help the recovery of gastritis.

Gastric sinusitis complications Complications, abdominal distension, abdominal pain, nausea and vomiting

Gastric sinusitis is a chronic inflammation that occurs in the antrum of the stomach. It can be divided into superficial and atrophic. Through years of observation and research, it has been found that there is a close relationship between gastric cancer and atrophic antral sinusitis. Many scholars have reported that the cancer rate of patients with atrophic gastritis is about 10%, and the risk of cancerous atrophic antral sinusitis is 20 times higher than that of normal people. In China, from the investigation of high and low incidence areas of gastric cancer, atrophic gastritis is found. The incidence rate is significantly increased in the high incidence area of gastric cancer. For the mechanism of atrophic antral sinusitis evolved into gastric cancer, it is generally believed that atrophic gastritis, abnormal changes in gastric mucosal function and structure, decreased gastric acid free acid, increased pH, increased bacterial bacteria in the stomach, especially in nitrates In the presence of enzyme-positive bacteria, nitro (NO3-) is reduced to nitroso (NO2-), which increases the content of nitroso (NO2-) in gastric juice, providing carcinogenicity to the synthesis of nitroso compounds in the stomach. The necessary conditions, but to what extent, how long it takes to become cancerous, is still unclear. In general, gastric mucosal biopsy is accompanied by severe intestinal gland metaplasia and metamorphosis, which is more likely to become cancerous.

Symptoms of antral sinus symptoms Common symptoms Stomach pain, stomach cramps, fullness, loss, nausea, vomiting, burning heart, loss of appetite

1, abdominal distension and abdominal pain: sinusitis is more common in men over the age of 30, upper abdominal bulging feeling, upper abdominal pain or severe pain, often a periodic attack, may be associated with hernia, acid reflux, upper abdomen burning, nausea , vomiting, weight loss, etc., a small number may have bleeding, there are asymptomatic. The disease is closely related to mental factors, and the tension of emotions, anger, stress or fear of malignant disease can exacerbate the symptoms.

2, causing gastric malignant transformation: antral sinusitis is a chronic inflammation that occurs in the antrum of the stomach, generally can be divided into superficial and atrophic. Observational studies have found a close relationship between gastric malignancy and atrophic antral sinusitis and antral sinusitis. The risk of malignant transformation of atrophic antral sinusitis is 20 times higher than that of normal people. The incidence of atrophic gastritis is significantly increased in the high incidence area of gastric malignant transformation.

3, leading to mental disorders: antral sinusitis and mental factors are closely related, emotional fluctuations or fear of tension, can make symptoms worse. The parasympathetic nervous system is also prone to attack when excited.

Examination of antral sinusitis

Imaging findings of antral sinusitis

1, antral irritability, the pyloric anterior region is often in a semi-contracted state, can not be as normal as the peristaltic wave will arrive when the capsule, but can be reduced to the stomach cavity is linear.

2, mucosal thickening, disorder, can be as wide as 1cm, the gastric antrum mucosa is mostly horizontal, the contour of the stomach wall is regular jagged, the edge of the serrated is also very smooth.

3, when the lesion develops to the muscular layer of hypertrophy, often manifested as antral centripetal stenosis, the shape is relatively fixed, generally can be contracted to very fine, but can not relax, and the normal segment is gradually transition or boundary is clear. The narrow section can show mucosal lines, most of which are longitudinal.

Diagnosis and differentiation of gastric antrum

Self-diagnosis of antral sinusitis

1, bloating: feel the stomach is swollen, food is not digested, or flatulence, appetite blocked, food can not go. About 70% of patients with antral sinusitis have this symptom.

2, stomach pain: sometimes pain before meals, sometimes pain after meals, and some people in the middle of the night three more pain. The feeling of stomach pain may not be severe, but it is dull pain, tenderness or dullness. The site of stomach pain is below the heart to the belly. About 85% of patients with antral sinusitis have this symptom.

3, heartburn: gastric mucosal congestion, too much stomach acid, will cause heartburn feeling, mainly the burning and fever of the stomach.

4, acid reflux: too much stomach acid, often acid reflux, there is a feeling of stomach acid from the stomach or full of up. About 50% of patients with antral sinusitis have this symptom.

5, loss of appetite: no appetite, can not eat, or see food, want to eat and dare not eat.

6. Weight loss: Some patients with stomach problems can feel appetite and can eat, but people lose weight and lose weight every day. This shows that the digestive function is not good. Although it is eaten, it is not fully absorbed.

7, nausea and vomiting: chronic gastritis patients often have nausea and other symptoms, especially chronic atrophic gastritis, nausea and vomiting is more prominent.

8, stomach cold: Many patients with stomach disease do not dare to eat cold, cold food, or the weather becomes cold, the temperature drops, the stomach is painful, diarrhea.

9, listless, poor color, poor sleep: patients with stomach problems often face sick, no spirit during the day, sleep at night, work efficiency, decreased interest in many things.

10, bad breath, black tongue coating: stomach disease patients often bad breath, mouth bitter, black tongue and other symptoms, accompanied by stomach pain, bloating.
