目的探讨肝癌手术切除后的序贯综合治疗,以达到有效防治肿瘤复发的目的。方法从我科收治的肝癌患者中挑选3例手术治疗后进行序贯综合治疗并取得良好效果病例，对其临床资料进行分析，从中获取有关肝癌术后治疗的经验。结果3例肝癌患者在我科手术后接受了积极的预防复发措施，虽最终均出现复发，但对待复发的肿瘤均采取积极的应对措施，获得了长期生存。结论对于肝癌手术切除后的患者进行积极的序贯性综合治疗有较好的临床意义，鼓励对术后复发病例进行积极序贯综合治疗。
Objective To summarize the research progress of programmed cell death protein 1 (PD-1)/programmed cell death protein-ligand 1 (PD-L1) inhibitors before liver transplantation of liver cancer. Method The literatures on the application of PD-1/PD-L1 inhibitors before liver transplantation of liver cancer were collected and reviewed. Results PD-1/PD-L1 inhibitors preoperatively treated liver transplantation recipients had a low incidence of postoperative rejection, and routine usage of hormone and immune tolerance induction therapy in liver transplantation recipients might reduce the incidence of rejection caused by PD-1/PD-L1 inhibitors. Conclusion Preoperative usage of PD-1/PD-L1 inhibitors have more benefits than risks for patients with advanced liver cancer.
ObjectiveTo investigate pathological changes of liver and risk factors for hepatic injury after trauma, in order to provide the instructions for clinical liver transplantation and accumulate the pathological data. MethodsWe retrospectively analyzed the clinical data of 142 patients who died after trauma between January 2010 and December 2014. Based on whether the patients had acute liver damage before dying, they were divided into two groups. The observation group had liver damage before dying, while the control group had not. Combined with the details of trauma, clinical data and autopsy results, we statistically analyzed the pathological changes of liver and risk factors for acute liver damage, including age, gender, trauma kind, trauma site, interval between trauma and hospitalization, damage degree, length of hypotension, the use of more than two vasopressors, large amount of blood transfusion, and complication of shock, infection, or underlying diseases. According to injury severity score (ISS) system, the damage degree was divided into mild damage (ISS<16), moderate damage (ISS≥16 and<25), and severe damage (ISS≥25). ResultsAmong the 142 patients, there were 45 in the observation group with varying degrees of liver cell necrosis, among whom there were 8 mild cases, 14 moderate and 23 severe. There were 97 patients in the control group without acute liver damage, and no significant changes were found in their hepatic tissue. Liver damage was not correlated with age, gender, damage kind, damage site, or pre-hospital time (P>0.05), while it was corrected with the degree of damage, time of hypotension (≥0.5 hour), the use of more than two vasopressors, large amount of blood transfusion (2 000 mL/24 hours), and combination of shock, infection, and other disease except for cardiac and pulmonary diseases (P<0.05). ConclusionWhen using donor livers from patients dying from trauma for transplantation, physicians should be alert to the factors discussed previously which can increase the risk of hepatic injury. Biopsy is useful to assess the suitability of donor livers prior to transplantation.
【摘要】目的探讨肝移植术后再次腹部手术的围手术期处理。方法对7例肝移植术后再次腹部手术患者的资料进行回顾性分析。结果5例择期手术患者围手术期平稳，痊愈出院。2例急诊手术患者中1例术后因并发上消化道应激穿孔、出血和切口感染自动出院。结论肝移植术后再次腹部择期手术的风险较急诊手术者低，与非肝移植行类似手术者相仿。
【Abstract】ObjectiveTo establish the stable model of orthtopic liver transplantation in rats.MethodsIn the light of Kamada’s method, the donor’s liver was perfused through portal vein before it was harvested,and the anastomosis was modified as continous suture with one suture for the suprahepatic inferior vena cava. Two hundred and ten orthotopic liver transplantations were performed in Wistar male rats according to this method. ResultsThe mean time of donor operation was 35 min, and that of recipient operation was 51 min. The mean cold preserving time of graft was 60 min.The anhepatic phase was about 17 min 〔(17.6±4.5) min〕. Nineteen rats died during operation. The causes of death included: bleeding of suprahepatic inferior vena cava, infrahepatic vena cava thrombosis, biliary obstruction, portal vein constriction and thrombosis, liver injury, bleeding of left subphrenic vein, infection, excessively deep anesthesia and respiratory failure. The 24hour survival was 91.0%(191/210),and the oneweek survival was 85.2%（179/210）.ConclusionThrough the modification of the anastomosis of suprahepatic inferior vena cava, the nonhepatic time of the recipients could be shortened,and the complications could be decreased. In this way, the survival of recipient rats after liver transplantation could be increased.
【摘要】目的 总结分析原位背驮式肝移植手术后并发症与供肝修整的关系。方法 回顾性分析我院12例行原位背驮式同种异体肝移植患者的资料。结果 本组12例肝移植围手术期无死亡； 手术成功率为100%。12例中行动脉血管变异整形2例，门静脉搭桥吻合1例； 各韧带修剪后缝合7例，未缝合5例。手术后发生腹腔内出血3例，其中2例与供肝修整有关，即修肝时各韧带未仔细缝合及结扎而导致细小血管出血，另1例系凝血功能障碍所致； 在供肝修整中注意了血管的变异整形及胆管的血供，术后无动脉及门静脉血管并发症和胆道并发症发生。结论 修肝质量的好坏，直接关系到术中植肝时手术操作的难度、术后供肝的存活质量、并发症的发生和患者的康复。
Objective To observe the effects of Thymosin α1 （Tα1） on acute rejection after liver transplantation and immune function of T cells. Methods Twenty recipients of liver transplantation due to primary hepatic carcinoma were divided into two groups: Tα1 group (n=10) and control group (n=10). Tα1 group received subcutaneous injection of Tα1 1.6 mg on the first day after liver transplantation and then twice a week for at least one month. Both Tα1 group and control group took same immunodepressants. Core biopsies were carried to compare the incidence rate of acute rejection between Tα1 group and control group. Peripheral T cellular immune function in these two groups was detected on 1 d before, 1 week, 2 weeks and 1 month after transplantation. Results There was not significant difference of incidence rate of acute rejection between Tα1 group and control group (Pgt;0.05). In the Tα1 group, CD4+, CD8+ lymphocyte cell counts and the CD4+/CD8+ ratio were significantly higher than those in the control group in 2 weeks and 1 month after transplantation (P＜0.05). Conclusion Use of Tα1 in recipients who also takes rountine immunosuppressants dose not increase the risk of occurring acute rejection after liver transplantation. Tα1 can significantly increase CD4+, CD8+ counts and CD4+/CD8+ ratio, which shows that Tα1 may improve recipients’ cellular immune function.
近年国内肝移植发展迅猛，已自然形成几大中心，在手术方式上也自有特色［1］。除转流条件下的经典肝移植，还有非转流条件下的经典肝移植及背驮式肝移植。各种手术方式都有其长处及不足之处，主要取决于术者经验及习惯。一般来讲背驮式对全身循环干扰较小，但切除病肝有时较困难，特别对乙肝肝硬变患者，因肝周的炎症、纤维化，肝组织常将肝后下腔静脉包绕，分离极为困难，出血较多。近年欧美及国内一些中心主张非转流下的经典肝移植［2，3］，优点是可减少手术时间，避免一些因转流产生的并发症，但缺点是可能造成循环不稳定及肾功损害，因此要求选择合适的病例，方能安全手术。我院仍习用转流条件下的肝移植术，并在此基础上提出了先转流后游离肝脏的手术方法，取得满意效果，现介绍讨论如下。
