Gastrostomy is a treatment method for patients with advanced esophageal cancer who cannot eat. Through surgery, a tube is drained into the stomach, and liquid food is delivered to the stomach through the tube, thus solving the problem of diet and enabling the patient's body to maintain a normal nutritional state. After gastrostomy, it is essential to pay attention to the cleaning and disinfection of the tube to prevent blockage. In the late stage of esophageal cancer, the esophagus may be obstructed, resulting in the inability to eat orally, and vomiting may occur after eating. To maintain normal nutritional status and solve the difficulty of eating orally, gastrostomy needs to be performed. Gastrostomy is a surgical procedure that introduces a tube from the outside into the stomach, and then injects liquid or semi-liquid food into the stomach through the tube, thus solving the difficulty of eating orally. Gastrostomy can ensure the normal nutritional status of the body and provide strong support for the next treatment of esophageal cancer. Intravenous nutritional fluid can also be injected through the fistula tube, and there are currently very mature intestinal nutritional fluid formulas that can maintain the nutritional status of the body. Prevention measures: After gastrostomy, patients must receive intravenous infusion, and only after the gastrointestinal motility function returns to normal can they eat some liquid food appropriately. Use physiological saline to clean the catheter every day to prevent blockage.
