Why is gastric lavage required before surgery for gastric cancer with pyloric obstruction?

Gastric cancer can be said to be a particularly serious malignant tumor. Once it occurs, it will cause various complications. For example, many patients also have pyloric obstruction, which leads to varying degrees of water, electrolyte and acid-base imbalance. For these patients, doctors often require gastric lavage before surgery. So what is the reason for doing this?

Generally speaking, gastric cancer with pyloric obstruction requires gastric lavage before surgery, because after pyloric obstruction occurs, the gastric contents remain in the stomach for a long time. At this time, if the contents of the stomach are not cleaned, it will affect the operation and even lead to failure of the operation. Indigestion of food will also form some toxins, which is not good for health. Hypertonic saline should be used to clean the residual food in the stomach before surgery to correct water and electrolyte disorders. For patients with anemia and hypoproteinemia, timely medication intervention should be carried out, and surgery should be performed after the condition stabilizes.

Gastric cancer with pyloric obstruction, washing the stomach with saline before surgery can reduce mucosal edema, make the procedure more convenient, more conducive to incision recovery, and reduce the probability of postoperative infection. Gastric cancer with pyloric obstruction, must be fully prepared before surgery. In addition to indwelling gastric tube flushing, nutritional support should be given to help regulate the gastric environment so that its various indicators meet the surgical indications. Try to perform the surgery when you are in the best physical condition, the effect will be better, and the harm to the body will be less.

Gastric cancer with pyloric obstruction is itself a particularly serious disease and the risk of surgery is very high, so patients must strictly follow the doctor's instructions and observe various preventive measures and try not to do it, otherwise it will affect the operation and effect of the surgery. Only by active cooperation can the risk be minimized.
