Symptoms of pyloric obstruction in gastric cancer

summary

Pyloric is the most narrow part of the digestive tract, the normal diameter is about 1.5cm, so it is prone to obstruction. Due to pyloric obstruction, gastric contents can not enter the intestines smoothly, but a large amount of * retention in the stomach leads to muscular thickening of the gastric wall, enlargement of the gastric cavity and inflammation, edema and erosion of the gastric mucosa. Clinically, the patient could not eat normally for a long time and vomited a lot, leading to severe malnutrition, hypoproteinemia and anemia, and severe dehydration, hypokalemia, alkalosis and other water and electrolyte disorders. Let's talk about the symptoms of pyloric obstruction in gastric cancer

Symptoms of pyloric obstruction in gastric cancer

1. Most patients have a long history of ulcer. With the progress of the disease, the stomachache gradually worsens, and there are belching, nausea and other symptoms. Patients are often anorexic due to gastric distension, and antacids are gradually ineffective. The stomach expanded gradually, the upper abdomen was full, and there were mobile masses. As the frequency of vomiting increased, dehydration became more and more serious and weight loss occurred. Patients with headache, fatigue, thirst, but fear of food, severe cases may appear collapse. Due to excessive loss of gastric juice, tetany and even convulsion may occur. Urine volume decreases gradually, and finally coma occurs.

2. Signs: emaciation, tiredness, dry skin and loss of elasticity, signs of vitamin deficiency, dry lips, tongue with moss, enophthalmos. The stomach type and gastric peristaltic wave moving from left to right could be seen. The upper abdominal drum sound and water vibration sound were obvious. The sound of air passing through the water can be heard, but it is rare. Chvostek's sign and Trousseau's sign were positive.

3. Blood routine examination can find mild anemia caused by malnutrition, blood biochemistry shows that sodium, potassium and chlorine are lower than normal, carbon dioxide binding force and pH value are increased, carbon dioxide partial pressure is also high, showing hypokalemic alkalosis. Non protein nitrogen or urea nitrogen was also higher than normal due to oliguria. Hypoproteinemia may occur due to long-term starvation. If anemia is serious and fecal occult blood is positive, the possibility of malignant ulcer should be considered. Gastric juice examination showed that the acidity of gastric juice in benign ulcer was high. If there is a lack of hydrochloric acid in gastric juice, further cytological examination and other examinations should be performed to exclude the tumor.
