| 1 | Transjugular intrahepatic portosystemic shunts and portal hypertension-related complications显示文摘Portal hypertension(PH)plays an important role in the natural history of cirrhosis,and is associated with several clinical consequences.The introduction of transjugular intrahepatic portosystemic shunts(TIPS)in the 1980s has been regarded as a major technical advance in the management of the PH-related complications.At present,polytetrafluoroethylene-covered stents are the preferred option over traditional bare metal stents.TIPS is currently indicated as a salvage therapy in patients with bleeding esophageal varices who fail standard treatment.Recently,applying TIPS early(within 72 h after admission)has been shown to be an effective and life-saving treatment in those with high-risk variceal bleeding.In addition,TIPS is recommended as the second-line treatment for secondary prophylaxis.For bleeding gastric varices,applying TIPS was able to achieve hemostasis in more than 90%of patients.More trials are needed to clarify the efficacy of TIPS compared with other treatment modalities,including cyanoacrylate injection and balloon retrograde transvenous obliteration of gastric varices.TIPS should also be considered in bleeding ectopic varices and refractory portal hypertensive gastropathy.In patients with refractory ascites,there is growing evidence that TIPS not only results in better control of ascites,but also improves long-term survivalin appropriately selected candidates.In addition,TIPS is a promising treatment for refractory hepatic hydrothorax.However,the role of TIPS in the treatment of hepatorenal and hepatopulmonary syndrome is not well defined.The advantage of TIPS is offset by a risk of developing hepatic encephalopathy,the most relevant postprocedural complication.Emerging data are addressing the determination the optimal time and patient selection for TIPS placement aiming at improving long-term treatment outcome.This review is aimed at summarizing the published data regarding the application of TIPS in the management of complications related to PH. | Sith Siramolpiwat | 2014 | World Journal of Gastroenterology2014,20,45: | 41 |

| 5 | Transjugular intrahepatic portosystemic shunt with covered stents for hepatocellular carcinoma with portal vein tumor thrombosis显示文摘AIM: To evaluate transjugular intrahepatic portosystemic shunt(TIPS) with covered stents for hepatocellular carcinoma(HCC) with main portal vein tumor thrombus(PVTT). METHODS: Eleven advanced HCC patients(all male, aged 37-78 years, mean: 54.3 ± 12.7 years) presented with acute massive upper gastrointestinal bleeding(n = 9) or refractory ascites(n = 2) due to tumor thrombus in the main portal vein. The diagnosis of PVTT was based on contrast-enhanced computed tomography and color Doppler sonography. The patients underwent TIPS with covered stents. Clinical characteristics and average survival time of 11 patients were analyzed. Portal vein pressure was assessed before and after TIPS. The follow-up period was 2-18 mo. RESULTS: TIPS with covered stents was successfully completed in all 11 patients. The mean portal vein pressure was reduced from 32.0 to 11.8 mmHg(t = 10.756, P = 0.000). Gastrointestinal bleeding was stopped in nine patients. Refractory ascites completely disappeared in one patient and was alleviated in another. Hepatic encephalopathy was observed in six patients and was resolved with drug therapy. During the follow-up, ultrasound indicated the patency of the shunt and there was no recurrence of symptoms. Death occurred 2-14 mo(mean: 5.67 mo) after TIPS in nine cases, which were all due to multiple organ failure. In the remaining two cases, the patients were still alive at the 16- and 18-mo follow-up, respectively. CONCLUSION: TIPS with covered stents for HCC patients with tumor thrombus in the main portal vein is technically feasible, and short-term efficacy is favorable. | Jian-Bo Zhao Chao Feng Qiao-Hua Zhu Xiao-Feng He Yan-Hao Li Yong Chen | 2014 | World Journal of Gastroenterology2014,20,6: | 12 |

| 7 | 肝硬化伴门静脉血栓经颈静脉肝内门体分流术后分流道失功能的影响因素分析显示文摘目的探讨肝硬化合并门静脉血栓(PVT)经颈静脉肝内门体分流术(TIPS)术后分流道的疗效。方法回顾性分析2015年1月至2018年5月收治的肝硬化伴PVT行TIPS术治疗患者44例,收集患者的临床基线资料,记录手术前后门静脉压力梯度(PVPG),术后随访3、6、12、18、24个月时分流道支架通畅情况,对影响因素进行单因素及多因素分析。结果44例均成功建立肝内门腔分流道,术后PVPG均较术前下降(P值均<0.01)。PVT行TIPS术后分流道狭窄率为18.2%(n=8),术后3、6、12、18、24个月累积分流道支架通畅率分别为95.5%、90.7%、90.7%、86.8%、74.4%。单因素分析显示糖尿病史、血小板水平及凝血酶原时间国际标准化比值与术后分流道失功能有关,多因素分析显示糖尿病史(P=0.007,OR=28.606)是术后分流道失功能的独立风险因素。结论肝硬化PVT行TIPS手术安全可行,可有效降低门静脉压力,糖尿病患者术后分流道失功能风险较高,临床上应加强对高危风险患者的防治干预。 | 李旭 王宏亮 周坦洋 陈圣群 聂春晖 张岳林 余子牛 周官辉 朱统寅 孙军辉 | 2020 | 中华肝脏病杂志2020,28,9: | 9 |
| 8 | Nationwide trends and predictors of inpatient mortality in 83884 transjugular intrahepatic portosystemic shunt显示文摘AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt(TIPS) in 15 years.METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospitalmortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients(OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients(OR = 1.347 vs non-transferred, P < 0.001), emergency admissions(OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region(OR = 1.449 vs West, P < 0.001) had significantly higher odds of inhospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death(OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure(OR = 8.246), acute kidney failure(OR = 4.359), hepatic encephalopathy(OR = 2.217) and esophageal variceal bleeding(OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites(OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders(OR = 2.823), coagulopathy(OR = 2.016), and lymphoma(OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death. | Edward Wolfgang Lee Andrew Kuei Sammy Saab Ronald W Busuttil Francisco Durazo Steven-Huy Han Mohamed M El-Kabany Justin P Mc Williams Stephen T Kee | 2016 | World Journal of Gastroenterology2016,22,25: | 7 |

| 15 | Prostacyclin decreases splanchnic vascular contractility in cirrhotic rats显示文摘BACKGROUND: Prostacyclin has been shown to increase portal hypertension, but the mechanism is unclear. This study aimed to investigate whether the overproduction of prostacyclin(PGI2) in cirrhosis participates in the splanchnic vascular hyporesponsiveness to vasoconstrictors in cirrhotic rats.METHODS: Cirrhotic model was created by subcutaneous injection of 60% carbon tetrachloride(CCl4) corn oil solution combined with intermittent drinking of 5% alcohol, and agematched rats served as controls. The isolated third-generation mesenteric arterioles were used to examine the contractile response to norepinephrine. The changes in vascular diameter were observed under a microscope imaging device. The plasma concentration of 6-ketone-prostaglandin F1α(6-keto-PGF1α, a stable metabolite of PGI2) was tested via enzyme immunoassays and the expression of cyclooxygenase(COX) in mesenteric arteries was detected by Western blotting.RESULTS: In parallel with the increase of plasma 6-ketoPGF1α, the contractile response of arterioles from cirrhotic rats to norepinephrine was significantly impaired compared with that from controls. Inhibition of PGI2 or protein kinase A with indomethacin or Rp-adenosine 3', 5'-cyclic monophosphothioate(Rp-cAMPS) partially reversed the vascular hypo-contractile response to norepinephrine in arterioles from cirrhotic rats.Indomethacin significantly decreased the plasma 6-keto-PGF1α.Furthermore, indomethacin significantly attenuated the effect of Rp-cAMPS on arterioles from cirrhotic rats. COX-1 expression was up-regulated in mesenteric arteries from cirrhotic rats,whereas COX-2 was not detectable in the mesenteric arteries from both cirrhotic and control rats.CONCLUSION: Enhanced COX-1 expression in cirrhotic rats resulted in elevated PGI2 production which partially contributedto the splanchnic vascular hyporesponsiveness to a vasoconstrictor via the protein kinase A pathway. | De-Jun Liu Wei Chen Yan-Miao Huo Wei Liu Jun-Feng Zhang Rong Hua Yong-Wei Sun | 2014 | Hepatobiliary & Pancreatic Diseases International2014,13,4: | 2 |
| 16 | 过氧化氢在肝硬化门静脉高压症内脏高动力循环中的作用显示文摘目的探讨过氧化氢(H2O2)在门静脉高压症内脏高动力循环形成中的作用。方法雄性SD大鼠皮下注射四氯化碳(CCl4)制备肝硬化门静脉高压症(PHT)模型。PHT组大鼠制备完成后随机分为2个亚组:聚乙二醇-过氧化氢酶(PEG-catalase)处理组(PHT+PEG组)和生理盐水(NS)处理组(PHT+NS组),分别用PEG或NS腹腔内注射10 U/(g·d),共14 d。测定大鼠门静脉压力(PP)、肠系膜微动脉对去甲肾上腺素(NE)的反应性、肠系膜动脉内H2O2含量。结果 (1)PHT组PP明显高于非PHT组,PEG对PHT组PP并无明显改善(P>0.05);(2)PHT组肠系膜微动脉对NE的反应性明显低于非PHT组,血管收缩率50%时NE的浓度EC50明显升高(P<0.01),PEG能部分改善这种低反应性(P<0.01);(3)PHT组肠系膜动脉内H2O2明显升高,PEG能使其减少。结论肝硬化PHT中过度生成的H2O2可通过降低肠系膜动脉对NE的反应性参与高动力循环的形成。 | 刘杰凡 刘巍 孙勇伟 | 2014 | 肝胆胰外科杂志2014,26,6: | 1 |
| 17 | 经颈静脉肝内门腔分流术中肝外门静脉穿刺致腹腔出血处理的初步经验显示文摘经颈静脉肝内门腔分流术(transjugular intrahepatic portosystemic shunt,TIPS)可有效控制因门静脉高压导致的急慢性食管胃底静脉曲张破裂出血、顽固性腹水等症状[1-6].肝外门静脉穿刺致腹腔出血是TIPS术中最危重的并发症之一,文献报道发生率为1% ~ 2%[7].以往采用裸支架行TIPS术,如果出现肝外门静脉穿刺引起出血,术中出血量巨大,患者可很快出现失血性休克表现,处理多以球囊压迫的同时转外科开腹修补.覆膜支架的出现则可以较好地处理此种情况.自2005年起,笔者尝试以覆膜材料支架(Fluency支架,Bard公司,德国)作为替代产品行TIPS术,取得了满意疗效[8],同时发现采用Fluency覆膜支架对于TIPS术中出现的肝外门静脉穿刺致腹腔的出血也可以获得满意的效果,现将初步经验整理报道如下. | 冯超 陈勇 李彦豪 何晓峰 曾庆乐 梅雀林 王江云 庞桦进 赵剑波 | 2015 | 中华放射学杂志2015,49,3: | 0 |
