Splenectomy reduces portal vein pressure reduces gastrointestinal bleeding and improves hypersplenism and can be a prudent option. Why is it a cautious choice? Because there are also many problems after splenectomy, such as: 1. low immune mechanism, prone to infectious disease infection crisis and high risk. 2, after splenectomy, the normal function of the spleen to remove senescent cells is lost, which will lead to hyperplateletemia, body blood vessels are prone to thrombosis, especially portal vein system thrombosis, and even hemorrhagic intestinal necrosis. 3. Other normal functions of the spleen are also lost. Therefore, the best ending is to reduce the size of the enlarged spleen while preserving part of the spleen, which can also reduce portal pressure to reduce gastrointestinal bleeding, improve hypersplenism and preserve the normal function of the spleen to remove senile pathological cells, and at the same time avoid vascular thrombosis. If the purpose is simply to prevent variceal bleeding, a combination of vein ligation, bonding, and sclerosis can be used. Of course, there are times when splenectomy should again be an option, such as when acute blood loss cannot be stopped by internal medicine or endoscopy, then peripancreatic vascular dissection with simultaneous splenectomy can be performed, or when for some reason partial splenic embolization cannot be performed.
