New technology improves gastric cancer surgical survival rate
Gastric cancer cells are quietly produced, quietly gathering and hiding power. Moreover, they are in the digestive tract, which is an important hub for the body to exchange with the external environment and absorb nutrients. Therefore, they have a very large space for activities. Unless we actively search for them, if they wait for them to initiate an active attack and expose their nature, It is often too late, causing irreparable damage to our health, or even a shift, and their dens have been distributed elsewhere.
Â
At the beginning, our weapons were very single, and they were the lancets that have been rumored on the rivers and lakes. Under the shadowless lamp, the knife light flashes and the lesion is invisible. Although this kind of imagination is very beautiful, I have to admit that in fact, with this weapon alone, we can only win a few battles. Because surgery is like a missile, although it can razor the terrorist nest, it is always difficult to completely eradicate tumor cells. Tumor cells are like a sly terrorist. Although they can destroy the old nest, it is inevitable that some cancer cells have been hidden in other parts of the body, and surgery cannot ensure complete elimination.
Â
Therefore, the doctors have improved on the tactics. We find that if these terrorists want to transfer to other parts, they will first pass through the sentry around the old nest, which is the lymph node of the stomach. Therefore, if the sentinel is also eliminated while removing the old nest of the disease during the operation, the efficiency of the terrorist attack can be greatly improved. The patient's postoperative life can be effectively extended. This is our current standard surgical procedure for gastric cancer: most of the stomach and lymph node dissection.
For a long time, in addition to surgery, we seem to have no better way to target this group of terrorists. The war situation has been deadlocked. Although more patients can get effective treatment, surgery alone is not ideal for some patients, especially those with advanced disease. The emergence of new weapons such as chemotherapy drugs has brought great changes to the war situation.
Â
Cancer cells are always engaged in division: cancer is cancer, and it is precisely because their cell division is not controlled. Therefore, a very effective way is to eliminate the separatist through drugs - chemotherapy drugs play this role. This new weapon has become a routine weapon in modern doctors fighting stomach cancer. According to the characteristics of different types of patients, a variety of tactics such as preoperative, intraoperative and postoperative use were designed, and the drug composition and dosage of chemotherapy were adjusted according to the battle conditions, and a good result was achieved.
Â
Generally speaking, for the stomach cancer, the doctors have been able to adopt a lot of methods, but there is a problem that the damage is large and the removal is not complete. No matter how good the surgery is, it is always necessary to remove some surrounding tissues, and the surgery itself is also a great trauma to the patient; in addition to eliminating the dividing molecules, radiotherapy will inevitably remove the normal proliferating cells together. There is no way to completely eliminate it.
Â
These operations can be done under the gastroscope without surgery. For patients with advanced disease and requiring surgery, we are now increasingly using minimally invasive surgery to ensure efficacy. It is like a high-precision guided missile that reduces civilian casualties while eliminating terrorists, and has a relatively small impact on the body. In the operation, we will also use lymph node developer. This is like labeling the lesions according to the map before the battle. It also labels the tumor sentries in the field to accurately guide the missile attacks, greatly increasing the detection rate of lymph nodes during surgery and improving the surgical results. .
