目的探究腹腔镜辅助远端胃癌D2根治术与传统开腹术对老年患者免疫功能及临床疗效的影响。方法 160例胃癌患者,随机分为腹腔镜辅助远端胃癌D2根治术组和传统开腹术组,各80例。对比分析两组患者的免疫功能及相关临床疗效。结果腹腔镜辅助远端胃癌D2根治术组患者的各项免疫功能情况及临床疗效均优于传统开腹术组(P<0.05)。结论采用腹腔镜辅助远端胃癌D2根治术对胃癌患者进行治疗,可有效减少并发症,提高治疗效果,值得临床推广使用。 Objective To investigate the effect of laparoscopic-assisted D2 distal root canal surgery and traditional laparotomy on immune function and clinical efficacy in elderly patients. Methods A total of 160 patients with gastric cancer were randomly divided into laparoscopic-assisted radical D2 group and distal laparotomy group, 80 cases each. Comparative analysis of two groups of patients with immune function and related clinical efficacy. Results All the immunological functions and clinical effects of laparoscopic D2-assisted radical gastrectomy in distal gastric cancer patients were better than that of the conventional open surgery group (P <0.05). Conclusion laparoscopic-assisted D2 distal root canal cancer treatment of patients with gastric cancer treatment, which can effectively reduce complications and improve the therapeutic effect, it is worth promoting the use of the clinic.
