目的 评价选择性介入治疗在原发性肝癌（HCC）门脉高压症中的应用价值。 方法 2008年11月－2011年3月，收治65例临床明确诊断的HCC伴门脉高压症患者，选择性使用肝动脉化学疗法（化疗）栓塞术、脾栓塞术、门静脉化疗栓塞术、门静脉支架、胃冠状静脉栓塞术等介入术式，术后通过观察临床指标、定期复查影像检查等了解病变转归，随访生存期并评价疗效。 结果 65例HCC患者均合并不同程度门静脉高压，其中门静脉癌栓46例中有37例显示肝动脉-门静脉分流，通过肝动脉及门静脉化疗栓塞术进行主瘤体及癌栓治疗。11例行门静脉支架置入术，支架置入后门静脉压较术前明显下降（P＜0.01），支架中位通畅时间为5.8个月。39例行胃冠状静脉和（或）胃短静脉栓塞术，术后有4例再次发生门脉高压性出血，再出血率10.26%。18例行脾动脉栓塞术，术后3个月血小板较术前显著升高（P＜0.01）。随访术后3、6、12及24个月的生存率分别为90.77%、69.23%、35.38%及13.85%。 结论 选择性联合使用各种介入术式是治疗HCC及其相关性门脉高压症的一种有效方法，可有效预防高危风险，延长患者生存期。
目的:探讨肝硬化门脉高压性结肠病与肝功能分级、食管静脉曲张、下消化道出血的关系以及内镜下特征,为诊治该类疾病提供一些依据。方法:回顾性分析48例肝硬化门脉高压患者临床表现及内镜特征,并对其并发的肝硬化门脉高压性结肠病进行分析。结果:48例肝硬化门脉高压患者中, 肝硬化门脉高压性结肠病发生率542%。 随着肝硬化门脉高压病程的延长,其门脉高压性结肠病的发生率明显增加,下消化道出血的机会也明显增加;而门脉高压性结肠病的发生与肝功能分级无关。结论:肝硬化门脉高压患者常出现门脉高压性结肠病。门脉高压性结肠病是肝硬化门脉高压患者下消化道出血的主要原因,但不是唯一原因。
门脉高压性胃病是肝硬变门脉高压症患者的主要并发症之一，病变几乎累及全部消化道，现就门脉高压性胃病的临床表现、病理特点、发病机理、诊断与治疗讨论如下……
【摘要】目的 探讨肝硬变门静脉高压症患者术前肝脏备功能的评估方法。方法 用Logistic多元回归法分析了78例门静脉高压症行断流术患者术后出现肝功能不全的相关因素，从中筛选与肝功不全关系最密切的危险因子。结果 术后发生肝功不全影响最大的因素依次为： 肝性脑病（EN）、血浆吲哚氰绿潴留试验（ICGR15 min）及门静脉充血指数（PCI）等，而术前的血清总胆红素（TBIL）、白蛋白（A）、凝血酶原时间（PT）、门静脉内径（dp）、门静脉流速（Vp）及门静脉流量（Qp）等因素，在多元回归中所占比例不大。结论 综合分析术前患者临床指标和肝功能实验室检查有助于评价肝硬变患者肝储备功能，预测手术风险及术后转归。
Objective To study the diagnosis and treatment of portal hypertension in secondary biliary cirrhosis(PHSBC). MethodsTwenty-five cases of PHSBC within recent 16 years in our hospital were analyzed. Their clinical, pathological and follow-up data were reviewed retrospectively. They were divided into 4 groups according to their primary diseases:13 patients with hepatolithiasis, 6 with postoperative stricture of biliary duct, 4 with malignancy of biliary duct and 2 with others.Results All patients were diagnosed clinically, and 4 were further pathologically confirmed. Eight cases were treated conservatively, while the remaining 17 underwent operations according to their primary diseases, and one combined with splenectomy and esophagogastric devascularization. The rate of discharge with improvement by surgical and non-surgical treatment was 64.7% and 37.5%, and hospital mortality was 17.6% and 12.5% respectively. Conclusion The diagnosis of PHSBC mainly depends on its characteristic clinical manifestations. The early surgical resolution of bile duct obstruction is the key to good prognosis. If complicated with rupture and hemorrhage of oesophagofundal varices, the surgical procedure should be considered carefully.
To investigate the change of the portal venous pressure (PVP), conjugated glycocholic acid (CGA) and pancreatic glucagon (PG) concentration in rats peripheral and portal venous blood in the course of experimental liver cirrhosis induced with carbon tetrachloride and to investigate the mentioned changes after portalazygous devascularization. The authors found that in the early stage of cirrhosis the PVP and the concentration of CGA and PG in peripheral venous blood were increased markedly, CGA in portal vein was decreased and PG in portal vein was increased in early stage of liver cirrhosis.With the extent of liver cirrhosis the indexes above changed more markedly. After portalazygous devascularization the concentration of CGA in peripheral vein in the cirrhotic rats was increased but PVP, the concentration of CGA in portal vein and PG in peripheral and portal vein did not change.There was no change in nornal rats. The results suggest that the variation in CGA in peripheral vein can accurately reflect the degree of damage to liver cells, thus making the diagnosis of liver cirrhosis earlier and judging the degree and prognosis of liver cirrhosis.The concentration of PG in portal venous and peripheral vein relate to PVP in liver cirrhosis.Portalazygous devascularization can maintain PVP and PG in portal vein and do not affect liver function of the control rats but it can damage liver cell in cirrhotic rats.
After analysising 15 patients with portal hypertension (PHT) in secondary biliary cirrhosis due to hepatolithiasis, the authors consider that the surgical procedure depends on indivedual’s specificity: majority of patients with PHT but no hemorrhage may be treated by removing the hepatobiliary stone, resolving the bile duct stricture and then reconstructing it as the first step. Whether or not to dispose of PHT depended on the postoperative condition. If the patient had previous hemorrhage and is accompanied by severe obstructive jaundice, splenectomy with shunt and simple biliary external drainage is the choice and removal of stone with biliary tract reconstruction will be performed in the second stage. Meanwhile, it is very important to monitor perioperative condition of the patient and treat the complications.
Electron spin resonance (ESR) spectroscopy and spin trapping agent PBN were applied to measure directly the changes of oxygen free redicals (OFR) in gastric mucosa of rats with portal hypertension (PHT) injured by shockreperfusion, and treated with superoxide dismutase (SOD), radix salviae miltiorrhizae (RSM), with concomitant monitoring activity of SOD and pathology of gastric mucosa. Results showed that the amount of OFR increased markedly in gastric mucosa of PHT rats during the shock-reperfusion. The pathological changes were in accordance with alteration of the amount of OFR and the activity of SOD. Gastric mucosa in PHT was more susceptible to shock-reperfusion insult than normal controls. The anti-oxidant SOD, RSM used at early stage exerted mild gastric mucosal insult through different mechanisms.
In the treatment of portal hypertension, association of both hassab operation and splenorenal shunt was performed selectively on six cases by authors from 1987 to 1994, and better results were obtatined in five patients. In this article, the experience and operative Techniques are introduced in detail, and he advantages of this procedure are evaluated.
