stomach tumor
Introduction
Introduction to gastric tumors Symptoms of gastric tumors rarely occur, and some symptoms occur after complications or malignant tumor growth, so they are easily ignored. Benign tumors in the pyloric area may have pyloric obstruction or pyloric obstruction or pedicled adenomas slide into the pyloric canal and duodenum, most of which are self-relieving. A few may have congestion, edema, and even intussusception, necrosis, and perforation. Peritonitis occurs. If the tumor shows ulcers, stomach upset, pain, and even bleeding may occur. Acute major bleeding can occur in leiomyomas and neurofibromas. Traditional Chinese medicine is the most important treatment for cancer treatment. According to the physiological characteristics and developmental rules of gastric cancer, the TCM expert group has heterogeneity, variability and metastasis. The combination of modern medicine and traditional Chinese medicine is used to induce Chinese medicine to break through the tumor tissue, block the blood circulation of the tumor tissue, order the normal cells to be ordered, directly enter the tumor to eliminate the phagocytosis, improve the microcirculation, and make the blood Increased oxygen metabolism, softened and reduced lesions. According to different conditions, different treatment methods are adopted, and the treatment is divided into several stages. It is suitable for patients who have not undergone surgery or have undergone surgical resection and postoperative recurrence of radiotherapy and chemotherapy. basic knowledge The proportion of illness: 0.0025% Susceptible people: no special people Mode of infection: non-infectious Complications: dysphagia, pyloric obstruction, peritonitis
Cause
Stomach tumor cause
Dietary factors (25%):
It is thought to play a role in the development of gastric cancer. These risk factors include high-salt, high-carbohydrate diets and large intakes of nitrates used as food preservatives. Inadequate intake of green leafy vegetables and fruits is also considered to be one of the risk factors. However, it has not been fully proven that these factors can cause gastric cancer.
Gastric polyps (20%):
It is an uncommon benign round neoplasm in the stomach and is considered to be a precancerous lesion and should be removed. Certain types of polyps, polyps larger than 12 mm, or multiple polyps are more susceptible to cancer.
Chronic disease (15%):
Refers to some stomach diseases that are prone to stomach cancer. Although gastric ulcer can be cancerous, the malignant rate is not high. In the past, many patients diagnosed with gastric ulcer were actually cancerous patients. After drug treatment, the symptoms can temporarily disappear, and even the ulcer can be reduced. Mistaken to think of benign gastric ulcer.
Prevention
Stomach cancer prevention
1. Develop good living habits, stop smoking and limit alcohol, and smoke. The World Health Organization predicts that if people no longer smoke, after 5 years, the world's cancer will be reduced by 1/3, and secondly, no alcohol, tobacco and alcohol. It is a very acidic acid substance. People who smoke and drink for a long time can easily lead to acidic body.
2, do not eat too much salty and spicy food, do not eat food that is too hot, too cold, expired and deteriorated, old and frail or have a certain genetics of the disease, as appropriate, eat some anti-tumor foods and high alkali content Alkaline foods maintain a good mental state.
Complication
Gastric tumor complications Complications, dysphagia, pyloric obstruction, peritonitis
Common complications are:
1. Benign tumors near the cardia may present with symptoms of dysphagia.
2. Benign tumors in the pyloric area may have pyloric obstruction or pyloric obstruction or pedicled adenoma slide into the pyloric canal and duodenum, most of which are self-relieving, a few may have congestion, edema, and even intussusception, necrosis, Peritonitis occurs after perforation.
3. If the tumor shows ulcers, stomach discomfort, pain, and even bleeding may occur.
4. Leiomyoma and neurofibroma can cause acute major bleeding.
Symptom
Stomach tumor symptoms Common symptoms Stomach pain, diarrhea, black stool, thin stool, deep stagnation, thin, poor, unexplained, fever, upper abdominal pain, upper abdominal mass
Early symptoms of gastric cancer are not obvious and are easily overlooked. Further development of the symptoms may indicate where the gastric cancer may be located. For example, after eating, fullness and abdominal discomfort, suggesting that the cancerous part is in the lower part of the stomach. Difficulties in eating, poor absorption of vitamins and minerals can cause weight loss and weakness in patients. Even if no other symptoms are caused, a small amount of blood loss will cause anemia. In rare cases, the patient can vomit a lot of blood or tar-like black stool.
Examine
Stomach tumor examination
(a) x-ray barium meal inspection
The examination is painless and easy for the patient to accept. X-ray barium meal double contrast angiography not only can make a qualitative diagnosis of gastric cancer (whether it is gastric cancer), but also can be used for quantitative diagnosis (the size, softness and mucosal fold changes of gastric cancer), which is one of the main methods for early diagnosis of gastric cancer. The diagnosis rate was 86.2%.
(two) fiber gastroscopy
The effective method for diagnosing early gastric cancer, combined with cytological examination and pathological examination, can greatly improve the positive rate of diagnosis. The use of Congo red and methylene blue in vivo staining under fiber endoscopy can help to improve the diagnosis rate of small gastric cancer and small gastric cancer. .
(3) Ultrasound diagnosis
1. Abdominal B-ultrasound: For the extra-abdominal mass, a thickened stomach wall can be seen on the surface. For the submucosal mass, 1 to 3 layers of gastric wall structure can be seen on the surface, and gastric leiomyoma or sarcoma can be identified. Divided into five layers, it can judge the depth and breadth of gastric wall infiltration of gastric cancer, and can judge the extragastric invasion of gastric cancer and the metastasis of liver and lymph nodes.
2. Ultrasound gastroscopy: While observing the original image of the endoscope, ultrasound images of the various layers below the gastric mucosa and adjacent organs around the stomach can be observed. At the same time, under the guidance of ultrasound, the deep tissue and the external organs can be puncture under the direct vision of the gastroscope, and the diagnosis of histological cytology can be achieved, and the lymph nodes around the stomach can be clearly metastasized.
Diagnosis
Stomach tumor diagnosis
It is difficult to diagnose a stomach tumor by clinical symptoms. X-ray tincture examination showed a rounded filling defect with a neat edge in the stomach, and the tumor showed signs of ulceration. However, X-ray barium examination does not identify the benign and malignant tumors, especially the early malignant tumors. Therefore, the examination of the gastroscope is particularly important. Under the gastroscope, the polypoid lesions are spherical, single or multiple, pedicled or broad-based. If the surface of the adenocarcinoma has nodules, erosions, ulcers or cauliflower-like changes, the color is paler than the surrounding mucosa, and the broad-based and surrounding gastric mucosa are more hypertrophic, it is mostly malignant. Leiomyoma is the most common in mesenchymal tumors. It is often small, has obvious boundaries, is not invaded to surrounding tissues, and can be treated with local excision. Because the benign tumor of the stomach has few symptoms in the clinic, once the symptoms appear, most of the tumors grow with complications or malignant changes. Therefore, once the diagnosis is confirmed, surgery must often be considered.
