摘要
目的:比较腹腔镜手术和开腹手术对结直肠癌根治术后机体免疫功能的影响。方法系统检索PubMed、Embase、the Cochrane Library、CNKI和万方数据库等有关腹腔镜和开腹结直肠癌根治术对机体免疫功能影响比较的随机对照研究,检索截至2013年8月。数据提取由2名评价员独立进行,采用RevMan 4.3.1统计软件进行数据分析。结果12项随机对照研究纳入分析,病例总数638例,其中腹腔镜组307例,开腹组331例。合并分析结果显示,两组术后24 h内血液C反应蛋白(CRP)水平(P=0.40)、术后1~3 d和术后4~7 d血浆淋巴细胞数量(P=0.92;P=0.64)、术后1~7 d血浆CD4+T细胞水平(P=0.63)、术后4~7 d血浆CD8+T细胞水平(P=0.09)和术后1~7 d血浆自然杀伤(NK)细胞水平(P=0.23)的差异均无统计学意义。但腹腔镜组术后24 h血清IL-6水平明显低于开腹组(WMD=-25.03,95%CI:-34.06~-15.99,P=0.000),术后1~3 d血浆CD8+T细胞水平腹腔镜组明显高于开腹组(WMD=0.05,95%CI:0.01~0.08,P=0.004)。结论相对于开腹结直肠癌根治手术,腹腔镜手术患者在术后急性炎性反应期内可能具有改善术后体液免疫的趋势,但急性反应期后,两者对机体免疫影响的差别不大。
Objective To compare the immune function after laparoscopic surgery (LS) and conventional open surgery (OS) for colorectal cancer (CRC). Methods PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), and Wanfang Database were systematically searched for randomized controlled trials published before August 2013 concerning the immunological difference between LS and OS. Data extraction was performed independently by two reviewers and data analysis was performed using Review Manager ver. 4.3.1. Results Twelve studies including 638 patients (307 in LS group and 331 in OS group) were eligible for analysis. Overall analysis demonstrated that no significant differences were identified for blood C-reactive protein level on postoperative days (POD) 0-1 (P=0.40), plasma lymphocyte count on POD 1-3 (P=0.92) and POD 4-7 (P=0.64), plasma CD4+ T cell count on POD 1-7(P=0.63), plasma CD8+ T cell count on POD 4-7 (P=0.09), and plasma NK cell count POD 1-3 (P=0.34) as well as POD 4-7 (P=0.46). Data analysis also showed that a significantly lower serum level of IL-6 on POD 0-1 after LS (WMD=-25.03, 95%CI:-34.06 to-15.99, P=0.000), and a significantly higher plasma level of CD8+ T cell count onPOD 1-3 after LS(WMD=0.05, 95%CI:0.01 to 0.08, P=0.004). Conclusions Although postoperatively short-term humoral immune function trends to be better after LS for CRC compared to OS, there is no sufficient evidence to support superior preservation of global immune function after acute reactive phase.
