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。
【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.
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.
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.
Objective To evaluate the efficacy of the subtotal splenectomy versus total splenectomy with gastroesophageal devascularization for patients of hepatic cirrhosis and portal hypertension. Methods We searched the Cochrane Library (Issue 2, 2008), MEDLINE (1966 to August, 2008), EMbase (1966 to August, 2008), the China Biological Medicine Database (1978 to August, 2008), Chinese Sci-tech Periodical Full-text Database (1989 to August, 2008) and Chinese Periodical Full-text Database (1994 to August, 2008), as well as hand-searched several related journals and conference proceedings for the randomized controlled trials involving the comparison of the efficacy of the subtotal splenectomy with the total splenectomy for the patients of the hepatic cirrhosis and portal hypertension. Results Three studies involving 136 patients were identified. The results of two studies indicated that both of the subtotal splenectomy increased less the peripheral platelet count and there was a statistically significant difference between the two groups [WMD= – 39.27, 95%CI (– 62.57, – 15.97)]. Two studies indicated that the serum tuftsin level was increased significantly after the subtotal splenectomy [WMD= 165.28, 95%CI (159.36, 171.21)]. One study indicated that both of the subtotal splenectomy and total splenectomy with gastroesophageal devascularization increased the peripheral white blood cell count and there was statistical difference between the two groups [WMD= – 0.93, 95%CI (– 1.52, – 0.34)]. There was no statistical difference in serum IgA level between the two groups. One study indicated the average fever time after the total splenectomy was longer than the subtotal splenectomy; there was statistical differences in 5 years survival rate between the two groups (Plt;0.05). Conclusions After the subtotal splenectomy the hypersplenism of patients suffered from hepatic cirrhosis and portal hypertension was corrected obviously and the blood cells were increased smoothly so that high blood viscosity was prevented and occurrence of the thrombotic diseases was decreased. And the immune system reserve functions of the patients with hepatic cirrhosis and portal hypertension were maintained. More randomized controlled trials, with large sample sizes, may lead to more accurate results.
Objective To establish the reliable model of hepatocirrhosis with portal hypertension. Methods Carbon tetrachloride was subcutaneous injected after devascularization of the circumference of the left renal vein. The morphology of liver, the extrahepatic portal system and portcaval collateral circulation were observed. Results The liver of rats underwent degeneration and necrosis of hepatocytes, and the normal architecture of the liver lobules was replaced by pseudolobules, which consisted of regenerative hepatocytes and fibrous septa. After 5 weeks, the portal pressure was significantly higher than that of control (Ｐ＜0.05). The diameter of esophageal vein was significantly larger than that of control at 15th week (Ｐ＜0.05). Conclusion This technique is simple and reliable and can be applied for various experimental studies on portal hypertension.
This study was to build a canine portal hypertension model by intra-portal administration of high polymer material polyurethane and organic solvent tetrahydrofuran mixed solutions in order to evaluate the effectiveness of the model. Twelve local crossbreed dogs were selected randomly, with intra-portal administration of 8% (weight/volume) polyurethane-tetrahydrofuran solutions through an incision in the upper abdomen to build the portal hypertension model. We measured the portal vein pressure before modeling, during modeling, and four-, eight-, and twelve-weeks after modeling, respectively. Then we evaluated the effectiveness of the model comparing values of data with those data obtained before modeling started, which were regarded as the normal values. The results showed that the portal vein pressure rose by 2.5 times after the solution administrated instantly as much as that before modeling, and maintained at 1.5 times after 4 weeks. This method presents an easy operation, low animal mortality and reliable model of portal hypertension. Its less abdominal adhesions and its ability in keeping normal anatomic structure specially make it suit for surgical research of portal hypertension.
