acute gastric mucosal lesions
Introduction
Introduction to acute gastric mucosal lesions Acute gastric mucosal lesions are characterized by different degrees of erosion, shallow ulcers and hemorrhage in the gastric mucosa. Acute mucosal erosion is mainly called acute erosive gastritis; mucosal hemorrhage is mainly called acute hemorrhagic gastritis. It occurs in a stress state, and a person with multiple ulcers may be called a stress ulcer. This disease is one of the common causes of upper gastrointestinal bleeding, accounting for about 20-30%. basic knowledge Proportion of disease: the probability of illness in the population is 0.04% Susceptible people: no specific population Mode of infection: non-infectious Complications: shock peritonitis
Cause
Causes of acute gastric mucosal lesions
First, drugs: a variety of drugs, common non-sterol anti-inflammatory drugs such as aspirin, indomethacin, phenylbutazone and other adrenocortical hormones, aspirin in the acidic environment is non-ionic and relative It is fat-soluble and can destroy the lipoprotein layer of gastric epithelial cells, weaken the mucosal barrier and cause hydrogen ions to reverse osmosis into the mucosa, causing inflammatory exudation, edema, erosion, hemorrhage or shallow ulcer. Other drugs such as digitalis, antibiotics, potassium salts , caffeine, etc. can also cause the disease.
Second, alcoholism: It is also a common cause of this disease, a large number of alcohol abuse caused by acute gastric mucosal erosion, bleeding.
Prevention
Acute gastric mucosal lesion prevention
Pay attention to diet, eat clean and digestible food, quit smoking, alcohol, drugs that have a stimulating effect on the gastric mucosa, preferably after meals.
Complication
Complications of acute gastric mucosal lesions Complications, shock peritonitis
Often accompanied by hemorrhagic shock, peritonitis and water, electrolyte metabolism disorders and other complications.
Symptom
Symptoms of acute gastric mucosal lesions Common symptoms Upper gastrointestinal bleeding, nausea, gastric mucosa, hyperemia, abdominal discomfort
Upper gastrointestinal bleeding is the most prominent symptom, which can be manifested as hematemesis or black feces. It is characterized by: 1 history of taking drugs, alcohol abuse or stress, 2 sudden onset, sudden hematemesis, black feces It can occur several hours or days after stressful lesions. 3 There are many bleedings, which can be intermittent, repeated many times, often leading to hemorrhagic shock. It can also be accompanied by upper abdominal discomfort, burning sensation, pain, and onset. Nausea, vomiting and acid reflux.
Examine
Examination of acute gastric mucosal lesions
1, X-ray barium meal test is often negative.
2, acute fiber endoscopy (24-48 hours), visible gastric mucosal localized or extensive patchy hemorrhage, clustered distribution, multiple erosion, shallow ulcers, occur in the bottom of the stomach, simply involved Gastric antrum is rare, and the lesion often disappears after 48 hours without leaving scars.
Diagnosis
Diagnosis and differentiation of acute gastric mucosal lesions
diagnosis
Can be diagnosed based on clinical performance and laboratory tests.
Differential diagnosis
First, acute corrosive gastritis is served with strong acid (sulfate, hydrochloric acid, nitric acid), strong alkali (sodium hydroxide, potassium hydroxide) or come to Sur, and other history, after the service caused by gastrointestinal burns, the mouth, throat, sternum and Severe pain in the upper abdomen, accompanied by swallowing pain, difficulty in swallowing, frequent nausea, vomiting, severe vomiting of blood, vomiting of mucous membranes with blood, prolapse, shock or symptoms of esophagus, gastric perforation, oral cavity, throat Inflammation at the site of contact, congestion, edema, erosion, necrotic mucosal exfoliation, ulceration or visible black, white sputum.
Second, acute appendicitis This disease may occur in the early stage of abdominal pain, nausea, vomiting, but as the disease progresses, the pain gradually turns to the right lower abdomen, and there is fixed tenderness and rebound tenderness, more with fever, white blood cells, neutrophils Significantly increased.
Third, cholecystitis, cholelithiasis has repeated abdominal pain, often in the right upper abdomen, can be radiated to the right shoulder, back, check the sclera, skin jaundice, right upper abdomen tenderness, Mo Fei's sign positive, or can be touched The enlarged gallbladder, the blood biliary redness, and the urinary triad test are helpful for diagnosis.
Fourth, other lobar pneumonia, myocardial infarction and other early stages of the disease may have different degrees of abdominal pain, nausea, vomiting, such as detailed medical history, physical examination and necessary auxiliary examination, it is not difficult to identify.
