精准肝蒂解剖技术辅助腹腔镜肝癌切除术的效果及对炎症免疫应激、肝功能的影响

Effect of Precise Hepatic Pedicle Dissection Assisted Laparoscopic Hepatectomy and Its Impact on Inflammatory Immune Stress and Liver Function

目的探讨精准肝蒂解剖技术辅助腹腔镜肝癌切除术的效果及对炎症免疫应激、肝功能的影响。方法选取达州市中心医院2019年10月至2022年6月114例原发性肝癌患者,按照随机数字表法分为常规组(n=57)与精准组(n=57)。2组均行腹腔镜肝癌切除术,常规组采用常规方法切除肝脏,精准组采用精准肝蒂解剖技术切除肝脏。比较2组手术指标、手术前后炎症-免疫指标[白介素-6(IL-6)、C反应蛋白(CRP)、肿瘤坏死因子-α(TNF-α)、免疫球蛋白A(IgA)、IgM、IgG]、肝功能[丙氨酸氨基转移酶(ALT)、天冬氨酸氨基转移酶(AST)、γ谷氨酰转肽酶(γ-GT)、总胆红素(TBIL)]、肿瘤因子[甲胎蛋白(AFP)、糖类抗原19-9(CA19-9)、胸苷激酶1(TK1)]水平、并发症发生率,并随访1 a,统计2组1 a复发率、生存率。结果2组手术时间、切缘阳性率差异无统计学意义(P>0.05);精准组术中出血量、术后引流量少于常规组,术后拔管时间、住院时间短于常规组(P<0.05);2组术后1 d、3 d、7 d血清IL-6、CRP、TNF-α、ALT、AST、γ-GT、TBIL水平呈升高后降低趋势,且精准组低于常规组(P<0.05),血清IgA、IgM、IgG水平呈降低后升高趋势,且精准组高于常规组(P<0.05);2组术后3个月血清AFP、CA19-9、TK1水平低于术前,精准组低于常规组(P<0.05);精准组并发症发生率5.26%(3/57)低于常规组17.54%(10/57)(P<0.05);随访1 a,精准组失访2例,常规组失访1例,精准组1 a复发率25.45%(14/55)低于常规组44.64%(25/56),1a生存率85.45%(47/55)高于常规组62.50%(35/56)(P<0.05)。结论精准肝蒂解剖技术应用于原发性肝癌腹腔镜肝切除术中能优化手术情况,减轻炎症免疫应激与肝功能损伤,减少并发症,还可明显抑制肿瘤因子表达,降低复发率,提高生存率。

Objective To explore the effect of precise liver pedicle dissection technique assisted laparoscopic hepatectomy on inflammatory immune stress and liver function.Methods A total of 114 patients with primary liver cancer in Dazhou Central Hospital from October 2019 to June 2022 were selected and divided into 57 patients each according to random number table method.Both groups underwent laparoscopic hepatectomy for liver cancer.The conventional group underwent routine liver resection,while the precision group underwent precise liver pedicle dissection.The surgical indicators,inflammatory-immune indicators[interleukin-6(IL-6),C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),immunoglobulin A(IgA),IgM,IgG],liver function[alanine aminotransferase(ALT),aspartate aminotransferase(AST),γ-glutamyltranspeptidase(γ-GT),total bilirubin(TBIL)],tumor factors[alpha-fetoprotein(AFP),carbohydrate antigen 19-9(CA19-9),thymidine kinase 1(TK1)],complication rate were compared between the two groups,and follow-up was conducted for 1 year.The recurrence rate and survival rate were statistically analyzed for both groups.Results There was no significant difference in operation time and positive rate of resection margin between the two groups(P>0.05).The intraoperative blood loss and postoperative drainage volume in the precision group were less than those in the conventional group,and the postoperative extubation time and hospital stay were shorter than those in the conventional group(P<0.05).After 1 day,3 days,and 7 days post-operation,the levels of serum IL-6,CRP,TNF-α,ALT,AST,γ-GT,and TBIL showed a decreasing trend after an initial increase.The precision group had lower levels compared to the standard group.The serum levels of IgA,IgM,and IgG showed an increasing trend after an initial decrease,with the precision group having higher levels than the standard group(P<0.05).After 3 months,the serum levels of AFP,CA19-9,and TK1 were lower than pre-operation levels,with the precision group showing lower levels compared to the standard group(P<0.05).The precision group had a lower complication rate of 5.26%(3/57)compared to the standard group's 17.54%(10/57)(P<0.05).During a 1-year follow-up,2 cases were lost to follow-up in the precision group,while 1 case was lost in the standard group.The precision group had a recurrence rate of 25.45%(14/55)after 1 year,lower than the standard group's 44.64%(25/56),with a survival rate of 85.45%(47/55)higher than the standard group's 62.50%(35/56)(P<0.05).Conclusion The application of precise liver pedicle dissection techniques in laparoscopic hepatectomy for primary liver cancer can optimize surgical conditions,reduce inflammatory immune stress and liver function injury,reduce complications,significantly inhibit tumor factor expression,reduce recurrence rate,and improve survival rate.
