Abstract Gastric cancer at the fundus of the stomach extends to the cardia or esophagus, causing obstruction of the lower end of the esophagus, and tumors adjacent to the pylorus are prone to cause pyloric obstruction. Vomiting may occur, a dilated stomach can be seen in the upper abdomen, and the sound of shaking water can be heard.
High-risk groups for gastric cancer are mainly men who have been infected with Helicobacter pylori, especially men with a weight of 20-25 kg over normal, aged between 50 and 80, who often eat salted vegetables or smoked meat and fish, etc. Smoking and alcoholism People who have undergone gastric surgery, gastric polyps, family neoplastic diseases, family history of gastric cancer, pernicious anemia, blood type A and have long-term work in an environment containing a lot of smoke, asbestos and nickel.
What are the complications of gastric cancer high-risk groups
1. When gastrointestinal bleeding is complicated, it is generally a small amount of bleeding, and major bleeding is relatively rare. About 5% of patients may experience massive bleeding, manifested as hematemesis and/or melena, occasionally as the first symptom. Dizziness, palpitations, tarry stools, and vomiting of brown matter may occur.
2. When the common bile duct is compressed by abdominal metastasis of gastric cancer, jaundice and clay-colored stool may occur.
3. Combined with pyloric obstruction, it is more common in gastric cancer originating from the pylorus and cardia. Gastric cancer at the fundus of the stomach extends to the cardia or esophagus, causing obstruction at the lower end of the esophagus, and tumors adjacent to the pylorus are prone to cause pyloric obstruction. Vomiting may occur, a dilated stomach can be seen in the upper abdomen, and the sound of shaking water can be heard.
4. Diffuse peritonitis caused by cancer perforation is less common than benign ulcer. It can be seen in ulcerative gastric cancer, mostly in ulcerative carcinoma with pyloric precursor. When the perforation is not covered by adhesions, it can cause peritonitis. Peritoneal irritation such as abdominal muscle stiffness and abdominal tenderness may occur.
5. Gastrointestinal fistula is formed, see discharge of indigestible food.
