Bleeding from the upper gastrointestinal tract (including the esophagus, stomach, duodenum, and upper jejunum) and from the bile duct or pancreatic duct is a common emergency in the elderly, with vomiting of blood or black feces as the main symptom. In case of massive bleeding, it is often accompanied by a series of clinical manifestations. The causes of upper gastrointestinal bleeding in the elderly are: 1. Peptic ulcer: the first one (about 50%). When excessive fatigue, emotional stress, improper diet and taking drugs that damage the gastric mucosa (such as aspirin) can cause peptic ulcer activity and cause bleeding. In elderly patients with upper gastrointestinal bleeding, there are more gastric ulcers than duodenal ulcers, with bleeding as the first symptom. 2, esophageal lesions: such as post-hepatitis cirrhosis or schistosomiasis cirrhosis patients can occur esophageal varices rupture bleeding, gastric acid reflux and corrosion; rough and hard food damage and increased intra-abdominal pressure, can become a cause of bleeding. About 30% of patients with esophageal varices have gastrointestinal bleeding not due to rupture of varices but due to combined ulcer disease or gastric mucosal lesions. In addition, esophageal ulcers and esophageal tumors in the elderly lead to bleeding. 3, hemorrhagic gastritis: long-term application of hormones and other irritating drugs in the elderly can damage the gastric mucosa and cause bleeding. 4.Malignant gastric lesions: such as gastric cancer, gastric sarcoma, etc. With age, the incidence of bleeding caused by gastric cancer increases in the elderly, mainly due to ischemic necrosis of cancer tissue causing erosion or ulcer erosion of blood vessels causing bleeding. 5.Other: such as severe lung heart disease, stroke and other serious illnesses; stress ulcer bleeding caused by poisoning, trauma, etc. Upper gastrointestinal bleeding is an emergency, should be examined while treatment: 1, for acute massive bleeding, should be absolutely bed rest, keep quiet; take a flat position, two knee bending or elevated lower limbs, should avoid low head position affects the respiratory function and blood aspiration into the trachea, and is conducive to maintaining the effective circulation of blood; only black feces can be without fasting. After the vomiting of blood stops, warm and cool rice soup, soybean milk or milk can be fed; patients with ruptured esophageal varices and bleeding should fast. After bleeding occurs, emergency treatment, including immediate fluid transfusion, should be performed along with examination. If necessary, blood transfusion or intragastric administration of cold saline lavage and necessary hemostatic drugs should be given. Drugs can also be sprayed locally through the endoscope, etc. In recent years, new techniques such as high-frequency electrocoagulation and laser hemostasis have been adopted with an efficiency of 94-95%. This method is suitable for those who are not suitable for emergency surgery and for those who have ruptured esophagogastric varices and bleeding in liver cirrhosis. Can also be injected under the endoscope sclerosing agent to stop bleeding. 2, should be under the guidance of doctors to actively treat the primary disease, such as peptic ulcer and liver cirrhosis. 3, life should be regular. Diet should be regular and moderate, do not overeat, avoid alcohol and tobacco, do not drink strong tea and coffee. 4, pay attention to the use of drugs. Should be used as little as possible or do not use drugs that stimulate the stomach, such as the need to use, should be added to protect the gastric mucosa of drugs. 5. Have regular medical checkups to detect early lesions and treat them in time. In case of anemia symptoms such as dizziness, you should go to the hospital for examination as soon as possible.
