Patients with hepatocellular carcinoma have a very short life expectancy if they receive no surgical interven- tion. A relatively new surgical technique termed ＂Associating Liver Partition and Portal Vein Ligation for Staged Hepa- tectomy＂（ALPPS） has been employed for inducing rapid hypertrophy of the future liver remnant for patients waiting for hepatectomy. As portal vein embolization may not result in satisfactory hypertrophy before tumor progression occurs, ALPPS can be an alternative for patients with advanced hepa- tocellular carcinoma. Herein we describe an ALPPS procedure with tumor thrombectomy for a patient who had a small left liver lobe and a large hepatocellular carcinoma involving the whole right liver lobe and the middle hepatic vein and extend- ing into the inferior vena cava. In the first-stage operation, the right portal vein was controlled and divided with a Hemolock. The right hepatic artery was well protected. Hepatic transec- tion was performed with a 1-cm margin from the tumor. The middle hepatic vein trunk was preserved. Ten days afterwards, there was significant hypertrophy of the left lateral section of the liver, and the second-stage operation was conducted. Ex- tended right hepatectomy and tumor thrombectomy were per- formed under sternotomy and total vascular exclusion. The patient had good recovery and was free of disease 10 months after the operation. ALPPS may be a good treatment option even for patients with advanced disease if carried out at high- volume centers.

AIM: To analyze the combined treatment of resection and intraoperative radiofrequency ablation (RFA) for multifocal hepatocellular carcinoma in terms of prognosis and surgical ***: This study was a retrospective case comparison study using prospectively collected data. The study covered the period from April 2001 to December 2006. The data of 200 patients with histologically confirmed hepatocellular carcinoma were reviewed. Nineteen patients (17 men and 2 women) having received resection in combination with RFA were chosen as subjects of the study (the combination group). Fiftyfour patients (43 men and 11 women) having received resection alone were selected for comparison (the resection group). The two groups matched tumor number and tumor size, and all the patients in the two groups displayed no tumor rupture, major vascular involvement and distant metastasis. Their demographics, preoperative assessment, disease recurrence patterns, overall survival and diseasefree survival were ***: In the combination group, the medianage was 65 years (range, 3477 years), the median tumor number was 3 (range, 29), and the median tumor size was 6 cm (range, 1.214 cm). In the resection group, the median age was 51.5 years (range, 2780 years, P = 0.003), the median tumor number was 3 (range, 29, P = 0.574), and the median tumor size was 6 cm (range, 114 cm, P = 0.782). The two groups were similar in characteristics of tumors and comorbidities, and had comparable results in preoperative liver function tests. All patients had ChildPugh class A status. Bilobar involvement occurred in 14 patients (73.6%) in the combination group and 3 patients (5.5%) in the resection group (P = 0.04). Six patients (32%) in the combination group and 35 patients (65%) in the resection group underwent major hepatectomy. Thirteen patients (68%) in the combination group and 19 patients (35%) in the resection group underwent minor hepatectomy (P = 0.012). The combination group had few

BACkGROUND: Living donor liver transplantation is a complex surgical operation. Treatment policies and operative techniques evolved in the last two decades. DATA SOURCES: Our center's experience in living donor liver transplantation was reviewed in conjunction with relevant publications in the literature. RESULTS: The surgical techniques and perioperative surgical therapeutics could be modified towards simplicity. Examples include regular inclusion of the middle hepatic vein without compromising the venous outflow of the donor's remnant left liver. This provides excellent venous outflow, which is crucial for a small-for-size graft. Immunosuppression and hepatitis B suppression are steroid free and hepatitis B immunoglobulin free respectively. CONCLUSION: The most practical way to achieve high graft and recipient survival rates with an acceptably low donor risk is through design of a protocol that simplifies the surgery and postoperative management.

智能机器人将人类带入了自原子弹、电灯或是印刷术以来最伟大的科技革命之中,同时智能机器也能走火入魔这一构思也向来是科幻作品的核心想象。纵观媒体发明的历史长河,对人工智能的恐慌并不新鲜,人们曾认为书写的发明和照相术将扼杀记忆和绘画,现在又照例指责数码正在毁灭模拟技术的独一性。人类应该冷静下来,采取对症下药的态度。有必要解构关于人与机器之差异的想象,而毋需躲避与智能机器人的交互谈话。人类物种虽然在作茧自缚,但同时又以进化与生态智能为基础,努力建设可持续全球体系。图像学研究的图像和文字同时包括了机器和人类的作品,因而相关的研究者应明确自己的任务:就文字与图像和智能机器人展开对话,在上述人类的生存努力中谋求与智能机器人携手合作。
