Some cases of cirrhosis may require spleen removal. Cirrhosis can cause portal hypertension, and portal hypertension can bring a series of problems, such as enlarged spleen, hypersplenism, as well as varices in the peri-oesophago-gastric veins, and in some cases, rupture and bleeding, and cirrhosis can sometimes cause a series of problems such as massive ascites. Once the above problems occur, the spleen may need to be removed for two main reasons: 1. Hypersplenism occurs because after a large spleen, it destroys red blood cells, white blood cells, and platelets, and the patient will show a three-series decline in low white blood cells, low platelets, and low red blood cells. There are a series of methods to solve hypersplenism, one of the more effective methods is to remove the spleen. 2. If there is gastrointestinal bleeding, ruptured esophagus-fundus bleeding, you need to do a dissection surgery and bypass surgery, in which splenectomy is likely to be part of the dissection surgery and bypass surgery. Not all bypass surgery requires splenectomy, for example, distal splenorenal vein bypass or preservation of the spleen, and part of the disconnected bypass surgery requires removal of the spleen.
