髋膝关节置换时治疗老年骨性关节炎的有效方法,既往研究表明肝硬化患者由于肝细胞不可逆的改变会出现凝血功能异常、白蛋白下降等情况,是髋膝关节置换术后并发症的危险因素之一。终末期肝病评分(MELD The Model for End-stage Liver Disease)最初是用于评估预测接受经颈静脉肝内门体分流术的肝病患者的生存期,随后被用来判断患者肝病的严重程度。但是MELD对于肝硬化患者髋膝

髋膝关节置换时治疗老年骨性关节炎的有效方法,既往研究表明肝硬化患者由于肝细胞不可逆的改变会出现凝血功能异常、白蛋白下降等情况,是髋膝关节置换术后并发症的危险因素之一。终末期肝病评分(MELD The Model for End-stage Liver Disease)最初是用于评估预测接受经颈静脉肝内门体分流术的肝病患者的生存期,随后被用来判断患者肝病的严重程度。但是MELD对于肝硬化患者髋膝关节置换术后的意义尚未得到研究。

美国波士顿的John V. Tiberi III 医生采用MELD评分评估预测肝硬化患者接受髋膝关节置换手术后的并发症情况,最终发现和没有肝硬化的病人相比,肝硬化的患者接受髋膝关节置换手术后内科并发症、手术并发症以及死亡的风险明显增高,当MELD评分超过10的患者并发症发生率显著增加,其研究结果发表在2014年9月的Clinical Orthopaedics and Related Research杂志上。

作者回顾性研究2000年1月1日至2012年11月30日之间合并肝硬化的择期髋膝关节置换患者,共115例,男性59例,女性56例,平均年龄62.9岁,平均随访4.4年,其中全髋关节置换60例,全膝关节置换55例。与此同时,在病例数据库中按照年龄、性别、手术年份等条件以1:1的比例抽取115例无肝硬化的患者作为对照组配对进行比较研究。

最终发现:和无肝硬化的患者相比,肝硬化患者的住院时间、转去护理中心的比例、90天内再入院率、泌尿系感染、肾衰竭、输血率、胃肠道出血、假体脱位、感染、90天内返修率、总体死亡率等情况均明显较差。和MELD评分小于10的患者相比,MELD评分超过10分的患者发生各种并发症的风险提高了接近三倍,而死亡的风险增加了4.1倍。

EASL 2014:3D+RBV治疗HCV1型感染非肝硬化者SVR率高

非初治丙肝病毒(HCV)感染者的治疗效果如何,与该患者既往治疗史有关。之前治疗过程中对聚乙二醇干扰素(IFN)/利巴韦林(RBV)无应答反应者,其接受再治疗的效果最不理想。为此,AbbVie和Enanta正稳步推进“丙肝鸡尾酒疗法”,其中包括了ABT-267、ABT-333和ABT-450。 三种药分别具有不同的作用机制:ABT-450是一种HCV NS3/4A蛋白酶抑制剂,由AbbVie和En

二步法切除术(ALPPS)用于传统意义上不可切除的肝硬化肝癌

中南大学湘雅医院肝脏外科王志明教授团队,采用世界肝脏外科最新技术,对1例原发性肝癌合并肝炎、肝硬化患者实施联合肝脏离断和门静脉结扎的“二步肝切除术”(ALPPS)获得成功。术后,患者康复良好并已于4月15日出院。据介绍,该手术的成功探索,为传统意义上不可切除的肝癌寻找到手术治疗的新途径。 据王志明介绍,2007年德国专家汉斯?施利特首创了ALPPS。该手术的原理是通过调整改变肝脏

EASL 2014:抗凝治疗不影响肝硬化患者上消化道出血预后

近期研究表明,肝硬化患者的高凝状态是发生血栓栓塞的危险因素,因此多采用抗凝治疗。曲张静脉破裂出血则是肝硬化的严重并发症。目前对于抗凝治疗是否会影响这类患者的预尚不知晓。 该研究纳入了52位正在接受抗凝治疗的上消化道出血患者。其中14位因门静脉血栓接受抗凝治疗,其余38位则因其他病因接受抗凝治疗。 研究匹配了104位未接受抗凝治疗的上消化道出血肝硬化患者,以肝硬化程度、年龄、性别、上消化道出血来源和
