Splenectomy patients who have undergone laparoscopic splenectomy treatment can usually be considered for a water trial on the first day after surgery when the gastric tube is removed. After the trial of drinking water is normal, if the patient does not have abdominal distension, abdominal pain, you can actively consider taking a semi-fluid or full-fluid diet, such as porridge. If the patient eats a semi-liquid diet for about 2-3 days normally, you can consider transitioning to a normal diet, but be careful not to drink alcohol, do not eat spicy, stimulating food. However, for patients undergoing open splenectomy, it is generally recommended to try drinking water after ventilation and getting out of bed. If the trial water intake is normal, then slowly transition to a semi-liquid diet or normal diet. For one month after surgery, patients are advised to eat a light diet and avoid spicy and stimulating foods and alcohol, especially chili peppers and garlic. After splenectomy, patients should have regular blood tests to check for changes in platelets. If the platelet value exceeds 600/mm^3 or more, the patient should actively consider taking antiplatelet drugs to prevent the formation of blood clots after the platelet is too high.
