Splenectomy for portal hypertension can only alleviate the problem of gastrointestinal bleeding and does not address the causes of portal hypertension such as cirrhosis, so portal hypertension is not solved by splenectomy. Portal hypertension refers to the clinical syndrome caused by elevated pressure in the portal vein system, which is a disorder of blood circulation in the portal vein due to multiple causes. Portal hypertension is not a single disease; all diseases that can cause obstruction, impairment or increased blood flow in the portal vein can cause portal hypertension. Portal hypertension can lead to splenomegaly, hypersplenism, susceptibility to splenic rupture or excessive platelet loss, and susceptibility to bleeding. Therefore, splenectomy for portal hypertension is mainly to prevent splenic rupture and hypersplenism and to alleviate the patient’s risk of gastrointestinal bleeding, but it does not change the nature of portal hypertension, so splenectomy does not resolve portal hypertension. Patients with portal hypertension can take propranolol tablets and other medications according to the doctor’s instructions, serious cases can be shunt surgery, usually pay attention to rest, less residue, low-salt diet, patients with hepatitis should be actively treating hepatitis, for liver protection, liver protection treatment.
