What Is Involved in Stomach Cancer Surgery?

Radical gastric cancer surgery, also known as curative resection of gastric cancer, refers to surgery in which the primary tumor is removed along with metastatic lymph nodes and affected tissues without residual tumors, making it possible to cure.

Radical gastric cancer

Radical gastric cancer surgery, also known as gastric cancer curative resection, refers to the primary tumor with metastatic lymph nodes and affected infiltration.

Strictly speaking, this surgical naming is based on the nature of the operation, which is a prerequisite. In clinical terms, they can be thoroughly divided into absolute radical surgery and relative radical surgery according to their first capital. The former refers to surgery with a clear and sufficient safety margin. For example, if there is metastasis at the first station, the operation goes beyond this station. Including the removal of lymph nodes at the second station, while the relative radical operation refers to lymph node dissection, only to the stations that have metastasized, but not beyond this station. Strictly speaking, gastric cancer that has been invaded by serosal membranes can only be a relative radical operation because of the possibility of tumor cells escaping and implanting in the abdominal cavity.

Comprehensive treatment of tumor classification is based on the patient's body condition, tumor pathological type, scope of invasion and development trend, and the existing treatment methods are planned and rationally applied to maximize the cure rate and improve the quality of life. It is a new scheme for treating tumors at the current stage, and is the basic principle of most tumor treatments.

Because only a small part of the stomach remains after radical resection of the gastric cancer or the jejunal interstitial is replaced after the total gastrectomy, the eating capacity is significantly reduced than the original. Therefore, patients should develop good eating habits, eat regularly, eat regularly and quantitatively, insist on eating less frequently and more, preferably 5 to 6 meals per day. Staple food and side dishes should be soft and easy to digest. Never overeating.

Prevent anemia

Proper selection of animal livers, fresh vegetables, etc. to increase the availability of various vitamins and minerals. It should be noted that after gastric cancer surgery, patients are prone to iron deficiency anemia, so it is appropriate to eat lean meat, fish, shrimp, animal blood, animal liver, egg yolk, soy products, and jujube, green leafy vegetables, sesame sauce and other proteins. With iron foods, prevent anemia.

Eat more fish

In the early postoperative period, you should eat in the order of water, clear fluid, liquid food, semi-fluid, soft food, and general food. The liquid diet is suitable for rice soup, egg soup, vegetable soup, and rice flour. Foods that can induce flatulence should be avoided. Semi-liquid diet should choose high-protein, high-calorie, high-vitamin, low-fat, fresh and digestible food. The best source of animal protein is fish, because fish is not only rich in protein content, the composition of amino acids and the ratio between them are similar to the human body, the utilization rate of fish protein can reach 96%, and the fat in fish contains unsaturated fatty acids It is high, and it is easy for the human body to digest and absorb, so we encourage eating more fish, such as yellow croaker, catfish and so on. After entering the ordinary diet, you should eat more fiber-containing foods such as vegetables and fruits to maintain smooth stool and promote toxin excretion.

Eat less sweets

1. A high-protein diet should be supplemented. Choose foods that are easy to digest and have a complete range of essential amino acids, such as fish, eggs, shrimp, lean meat, and soy products. Protein energy accounts for 15% to 20% of the total energy, such as a weight of 70 A person with a kilogram can consume 70 to 140 grams of protein per day.

2. Too much sugar intake can easily cause hypertonic dumping syndrome (discomfort after eating caused by gastrectomy). Therefore, sugars should be properly controlled, and energy supply of sugars should account for 50% to 60% of total calories. To avoid ingestion of oversweet foods, starch foods should be the mainstay.

3, fat energy supply does not exceed 35% of the total energy, avoid eating animal fats, should choose digestible and absorbable fats, such as vegetable oil, cream, egg yolk, etc. If a small number of patients have fatty rash after surgery (referring to pulling a lot of fat particles during diarrhea), they should reduce their fat intake.

Chew slowly

The grinding function of the stomach is lacking after surgery, so the chewing function of the teeth should play a more important role. For coarser and less digestible foods, chew slowly. If you want to eat soups or drinks, you should pay attention to the dry and thin, and try to add soups before or 30 minutes after a meal to prevent food from being discharged too quickly and affecting digestion and absorption. After meals, you should rest in the lateral position to extend the emptying time of the food and allow it to fully digest and absorb.

If the diet of postoperative gastric cancer can pay attention to the above matters, it will definitely reduce the pain of patients, promote wound recovery, improve the quality of life, and provide a better physical basis for the next treatment.

Warm reminder: if the postoperative diet of gastric cancer is improper, it will cause harm to the body and induce complications. Therefore, as a family member of gastric cancer patients, it is necessary to provide patients with a reasonable postoperative diet for gastric cancer from a scientific perspective, so that the patient's body can be as early as possible recovery. Studies have shown that patients with gastric cancer combined with a scientific diet can improve patients' immunity and resistance, increase the success rate of surgery, and effectively avoid recurrence and metastasis.
