Abstract: The spleen is the most important immune organ of the human body,playing an important role in maintaining the immune balance of the body.More and more studies have shown that the body's specific and nonspecific immune function decreases after splenectomy,and as a result,infection and tumor susceptibility increases.Laparoscopic partial splenectomy,a new surgical method of spleen preservation,has gotten increasing clinical application.Laparoscopic partial splenectomy is minimally invasive and is associated with quick recovery;however,this operation is difficult to perform and often causes bleeding.In recent years,our department has used bipolar radiofrequency Habib 4X in laparoscopic partial splenectomy to achieve good results.This article focuses on the methods and techniques of laparoscopic partial splenectomy.
