Abstract:【Objective】 To study the influence of laparoscopic splenectomy on the early postoperative immune function with traumatic spleen rupture. 【Methods】 32 cases with traumatic spleen rupture were randomly divided into the laparoscopic splenectomy (LS) group and open splenectomy (OS) group. The changes of interleukin-2 (IL-2) and human leukocyte antigen-DR (HLA-DR) on the surface of mononuclear cells in peripheral blood were compared between the two groups perioperative. 【Results】 The levels of IL-2 and HLA-DR show no significant difference 30 minutes after surgery between both groups (P >0.05); The level of IL-2: at first day after surgery: there were significant decreases in both groups (P <0.05), but the OS group'level was significantly reduced relative to the LS group'level (P <0.05); At day 4 postoperative : the OS group'level was increased, but still significantly lower than the preoperative level (P <0.05), and the LS group'level returned to the preoperative level (P >0.05), but was significantly higher than the OS group'level (P <0.05); The expression of HLA-DR: At first day after surgery: The levels of the two groups both were significant decreased relative to the preoperative levels (P <0.05), but had no significant difference between groups (P >0.05); At the fourth day postoperative: the levels of the two groups both were increased, but the LS group'level was significantly higher than the OS group'level (P <0.05). 【Conclusion】 The LS and OS both have a certain degree of inhibition on the immune function of early postoperative body, but the LS caused inhibition is smaller.
