| 1 | Hepatolithiasis and intrahepatic cholangiocarcinoma: A review显示文摘Although the incidence of hepatolithiasis is decreasing as the pattern of gallstone disease changes in Asia, the prevalence of hepatolithiasis is persistently high, especially in Far Eastern countries. Hepatolithiasis is an established risk factor for cholangiocarcinoma(CCA), and chronic proliferative inflammation may be involved in biliary carcinogenesis and in inducing the upregulation of cell-proliferating factors. With the use of advanced imaging modalities, there has been much improvement in the management of hepatolithiasis and the diagnosis of hepatolithiasis-associated CCA(HLCCA). However, there are many problems in managing the strictures in hepatolithiasis and differentiating them from infiltrating types of CCA. Surgical resection is recommended in cases of single lobe hepatolithiasis with atrophy, uncontrolled stricture, symptom duration of more than 10 years, and long history of biliaryenteric anastomosis. Even after resection, patients should be followed with caution for development of HL-CCA, because HL-CCA is an independent prognostic factor for survival. It is not yet clear whether hepatic resection can reduce the occurrence of subsequent HL-CCA. Furthermore, there are no consistent findings regarding prediction of subsequent HL-CCA in patients with hepatolithiasis. In the management of hepatolithiasis, important factors are the reduction of recurrence of cholangitis and suspicion of unrecognized HL-CCA. | Hyo Jung Kim Jae Seon Kim Moon Kyung Joo Beom Jae Lee Ji Hoon Kim Jong Eun Yeon Jong-Jae Park Kwan Soo Byun Young-Tae Bak | 2015 | World Journal of Gastroenterology2015，21，48： | 63 |
| 2 | Review of a challenging clinical issue:Intrahepatic cholestasis of pregnancy显示文摘Intrahepatic cholestasis of pregnancy(ICP) is a reversible pregnancy-specific cholestatic condition characterized by pruritus, elevated liver enzymes, and increased serum bile acids. It commences usually in the late second or third trimester, and quickly resolves after delivery. The incidence is higher in South American and Scandinavian countries(9.2%-15.6% and 1.5%, respectively) than in Europe(0.1%-0.2%). The etiology is multifactorial where genetic, endocrine, and environmental factors interact. Maternal outcome is usually benign, whereas fetal complications such as preterm labor, meconium staining, fetal distress, and sudden intrauterine fetal demise not infrequently lead to considerable perinatal morbidity and mortality. Ursodeoxycholic acid is shown to be the most efficient therapeutic agent with proven safety and efficacy. Management of ICP consists of careful monitoring of maternal hepatic function tests and serum bile acid levels in addition to the assessment of fetal well-being and timely delivery after completion of fetal pulmonary maturity. This review focuses on the current concepts about ICP based on recent literature data and presents an update regarding the diagnosis and management of this challenging issue. | Sebiha Ozkan Yasin Ceylan Orhan Veli Ozkan Sule Yildirim | 2015 | World Journal of Gastroenterology2015，21，23： | 53 |
| 3 | Portal vein thrombosis in cirrhosis: Controversies and latest developments显示文摘Portal vein thrombosis(PVT) is encountered in livercirrhosis, particularly in advanced disease. It has been a feared complication of cirrhosis, attributed to significant worsening of liver disease, poorer clinical outcomes and potential inoperability at liver transplantation; also catastrophic events such as acute intestinal ischaemia. Optimal management of PVT has not yet been addressed in any consensus publication.We review current literature on PVT in cirrhosis; its prevalence, pathophysiology, diagnosis, impact on the natural history of cirrhosis and liver transplantation,and management. Studies were identified by a search strategy using MEDLINE and Google Scholar. The incidence of PVT increases with increasing severity of liver disease: less than 1% in well-compensated cirrhosis, 7.4%-16% in advanced cirrhosis. Prevalence in patients undergoing liver transplantation is 5%-16%.PVT frequently regresses instead of uniform thrombus progression. PVT is not associated with increased risk of mortality. Optimal management has not been addressed in any consensus publication. We propose areas for future research to address unresolved clinical questions. | Damian J Harding M Thamara PR Perera Frederick Chen Simon Olliff Dhiraj Tripathi | 2015 | World Journal of Gastroenterology2015，21，22： | 42 |
| 4 | 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 | Pathological classification of intrahepatic cholangiocarcinoma based on a new concept显示文摘Intrahepatic cholangiocarcinoma (ICC) arises from the lining epithelium and peribiliary glands of the intrahepatic biliary tree and shows variable cholangiocytic dif-f-e-re-ntiation. To date-,ICC was large-ly classifie-d into adenocarcinoma and rare variants. Herein,we propose to subclassify the former,based on recent progress in the-study of-ICC including the-gross classification and hepatic progenitor/stem cells and on the pathological similarities between biliary and pancreatic neoplasms. That is,ICC is classifiable into the conventional (bile duct) type,the bile ductular type,the intraductal neoplasm type and rare variants. The conventional type is further divided into the small duct type (peripheral type) and large bile duct type (perihilar type). The former is a tubular or micropapillary adenocarcinoma while the latter involves the intrahepatic large bile duct. Bile ductular type resembles proliferated bile ductules and shows a replacing growth of the hepatic parenchyma.Hepatic progenitor cell or stem cell phenotypes such as neural cell adhesion molecule expression are frequently expressed in the bile ductular type. Intraductal type includes papillary and tubular neoplasms of the bile duct (IPNBs and ITNBs) and a superficial spreading type. IPNB and ITNB show a spectrum from a preneoplastic borderline lesion to carcinoma and may have pancreatic counterparts. At invasive sites,IPNB is associated with the conventional bile duct ICC and mucinous carcinoma. Biliary mucinous cystic neoplasm with ovarian-like stroma in its wall is different from IPNB,particularly IPNB showing cystic dilatation of the affected ducts. Rare variants of ICC include squamous/adenosquamous cell carcinoma,mucinous/signet ring cell carcinoma,clear cell type,undifferentiated type,neuroendocrine carcinoma and so on. This classification of-ICC may ope-n up a ne-w fie-ld of-re-se-arch of-ICC and contribute-to the-clini cal approach to ICC. | Yasuni Nakanuma Yasunori Sato Kenichi Harada Mokoto Sasaski Hiroko Ikeda | 2010 | World Journal of Hepatology2010，2，12： | 34 |
| 6 | Routine lymph node dissection may be not suitable for all intrahepatic cholangiocarcinoma patients: Results of a monocentric series显示文摘AIM:To investigate the indications for lymph node dissection(LND)in intrahepatic cholangiocarcinoma patients.METHODS:A retrospective analysis was conducted on 124 intrahepatic cholangiocarcinoma(ICC)patients who had undergone surgical resection of ICC from January 2006 to December 2007.Curative resection was attempted for all patients unless there were metastases to lymph nodes(LNs)beyond the hepatoduodenal ligament.Prophylactic LND was performed in patients in whom any enlarged LNs had been suspicious for metastases.The patients were classified according to the LND and LN metastases.Clinicopathologic,operative,and long-term survival data were collected retrospectively.The impact on survival of LND during primary resection was analyzed.RESULTS:Of 53 patients who had undergone hepatic resection with curative intent combined with regional LND,11 had lymph nodes metastases.Whether or not patients without lymph node involvement had undergone LND made no significant difference to their survival(P=0.822).Five patients with multiple tumors and involvement of lymph nodes underwent hepatic resection with LND;their survival curve did not differ significantly from that of the palliative resection group(P=0.744).However,there were significant differences in survival between patients with lymph node involvement and a solitary tumor who underwent hepatic resection with LND and the palliative resection group(median survival time 12 mo vs 6.0 mo,P=0.013).CONCLUSION:ICC patients without lymph node involvement and patients with multiple tumors and lymph node metastases may not benefit from aggressive lymphadenectomy.Routine LND should be considered with discretion. | Dong-Yu Li Hai-Bin Zhang Ning Yang Yuan Quan Guang-Shun Yang | 2013 | World Journal of Gastroenterology2013，19，47： | 31 |

| 8 | TIPS improves liver transplantation-free survival in cirrhotic patients with refractory ascites:An updated meta-analysis显示文摘AIM:To compare the liver transplantation-free(LTF)survival rates between patients who underwent transjugular intrahepatic portosystemic shunts(TIPS)and those who underwent paracentesis by an updated meta-analysis that pools the effects of both number of deaths and time to death.METHODS:MEDLINE,EMBASE,and the Cochrane Library were searched from the inception to October2012.LTF survival,liver transplantation,liver diseaserelated death,non-liver disease-related death,recurrent ascites,hepatic encephalopathy(HE)and severe HE,and hepatorenal syndrome were assessed as outcomes.LTF survival was estimated using a HR with a95%CI.Other outcomes were estimated using OR with95%CIs.Sensitivity analyses were performed to assess the effects of potential outliers in the studies according to the risk of bias and the study characteristics.RESULTS:Six randomized controlled trials with 390patients were included.In comparison to paracentesis,TIPS significantly improved LTF survival(HR=0.61,95%CI:0.46-0.82,P<0.001).TIPS also significantly decreased liver disease-related death(OR=0.62,95%CI:0.39-0.98,P=0.04),recurrent ascites(OR=0.15,95%CI:0.09-0.24,P<0.001)and hepatorenal syndrome(OR=0.32,95%CI:0.12-0.86,P=0.02).However,TIPS increased the risk of HE(OR=2.95,95%CI:1.87-4.66,P=0.02)and severe HE(OR=2.18,95%CI:1.27-3.76,P=0.005).CONCLUSION:TIPS significantly improved the LTF survival of cirrhotic patients with refractory ascites and decreased the risk of recurrent ascites and hepatorenal syndrome with the cost of increased risk of HE compared with paracentesis.Further studies are warranted to validate the survival benefit of TIPS in clinical practice settings. | Ming Bai Xing-Shun Qi Zhi-Ping Yang Man Yang Dai-Ming Fan Guo-Hong Han | 2014 | World Journal of Gastroenterology2014，20，10： | 29 |
| 9 | Clinical effects and complications of TIPS for portal hypertension due to cirrhosis:A single center显示文摘AIM:To determine the clinical effects and complications of transjugular intrahepatic portosystemic shunt(TIPS)for portal hypertension due to cirrhosis.METHODS:Two hundred and eighty patients with portal hypertension due to cirrhosis who underwent TIPS were retrospectively evaluated.Portal trunk pressure was measured before and after surgery.The changes in hemodynamics and the condition of the stent were assessed by ultrasound and the esophageal and fundic veins observed endoscopically.RESULTS:The success rate of TIPS was 99.3%.The portal trunk pressure was 26.8±3.6 cmH2O after surgery and 46.5±3.4 cmH2O before surgery(P<0.01).The velocity of blood flow in the portal vein increased.The internal diameters of the portal and splenic veins were reduced.The short-term hemostasis rate was100%.Esophageal varices disappeared completely in68%of patients and were obviously reduced in 32%.Varices of the stomach fundus disappeared completely in 80%and were obviously reduced in 20%of patients.Ascites disappeared in 62%,were markedly reduced in 24%,but were still apparent in 14%of patients.The total effective rate of ascites reduction was 86%.Hydrothorax completely disappeared in 100%of patients.The incidence of post-operative stent stenosis was 24%at 12 mo and 34%at 24 mo.The incidence of post-operative hepatic encephalopathy was 12%at3 mo,17%at 6 mo and 19%at 12 mo.The incidence of post-operative recurrent hemorrhage was 9%at 12mo,19%at 24 mo and 35%at 36 mo.The cumulative survival rate was 86%at 12 mo,81%at 24 mo,75%at 36 mo,57%at 48 mo and 45%at 60 mo.CONCLUSION:TIPS can effectively lower portal hypertension due to cirrhosis.It is significantly effective for hemorrhage of the digestive tract due to rupture of esophageal and fundic veins and for ascites and hydrothorax caused by portal hypertension. | Jian-Ping Qin Ming-De Jiang Wen Tang Xiao-Ling Wu Xin Yao Wei-Zheng Zeng Hui Xu Qian-Wen He Ming Gu | 2013 | World Journal of Gastroenterology2013，19，44： | 25 |
| 10 | Transjugular intrahepatic portosystemic shunt for the management of acute variceal hemorrhage显示文摘Acute variceal hemorrhage,a life-threatening condition that requires a multidisciplinary approach for effective therapy,is defined as visible bleeding from an esophageal or gastric varix at the time of endoscopy,the presence of large esophageal varices with recent stigmata of bleeding,or fresh blood visible in the stomach with no other source of bleeding identified.Transfusion of blood products,pharmacological treatments and early endoscopic therapy are often effective;however,if primary hemostasis cannot be obtained or if uncontrollable early rebleeding occurs,transjugular intrahepatic portosystemic shunt(TIPS)is recommended as rescue treatment.The TIPS represents a major advance in the treatment of complications of portal hypertension.Acute variceal hemorrhage that is poorly controlled with endoscopic therapy is generally well controlled with TIPS,which has a 90%to 100%success rate.However,TIPS is associated with a mortality of 30%to 50%in such a setting.Emergency TIPS should be considered early in patients with refractory variceal bleeding once medical treatment and endoscopic sclerotherapy failure,before the clinical condition worsens.Furthermore,admission to specialized centers is mandatory in such a setting and regional protocols are essential to be organized effectively.This review article discusses initial management and then focuses on the specific role of TIPS as a primary therapy to control acute variceal hemorrhage,particularly as a rescue therapy following failure of endoscopic approaches. | Romaric Loffroy Louis Estivalet Violaine Cherblanc Sylvain Favelier Pierre Pottecher Samia Hamza Anne Minello Patrick Hillon Pierre Thouant Pierre-Henri Lefevre Denis Krausé Jean-Pierre Cercueil | 2013 | World Journal of Gastroenterology2013，19，37： | 25 |
| 11 | Shunting branch of portal vein and stent position predict survival after transjugular intrahepatic portosystemic shunt显示文摘AIM:To evaluate the effect of the shunting branch of the portal vein(PV)(left or right)and the initial stent position(optimal or suboptimal)of a transjugular intrahepatic portosystemic shunt(TIPS).METHODS:We retrospectively reviewed 307 consecu5tive cirrhotic patients who underwent TIPS placement for variceal bleeding from March 2001 to July 2010 at our center.The left PV was used in 221 patients and the right PV in the remaining 86 patients.And,224 and83 patients have optimal stent position and sub-optimal stent positions,respectively.The patients were followed until October 2011 or their death.Hepatic encephalopathy,shunt dysfunction,and survival were evaluated as outcomes.The difference between the groups was compared by Kaplan-Meier analysis.A Cox regression model was employed to evaluate the predictors.RESULTS:Among the patients who underwent TIPS to the left PV,the risk of hepatic encephalopathy(P=0.002)and mortality were lower(P<0.001)compared to those to the right PV.Patients who underwent TIPS with optimal initial stent position had a higher primary patency(P<0.001)and better survival(P=0.006)than those with suboptimal initial stent position.The shunting branch of the portal vein and the initial stent position were independent predictors of hepatic encephalopathy and shunt dysfunction after TIPS,respectively.And,both were independent predictors of survival.CONCLUSION:TIPS placed to the left portal vein with optimal stent position may reduce the risk of hepatic encephalopathy and improve the primary patency rates,thereby prolonging survival. | Ming Bai Chuang-Ye He Xing-Shun Qi Zhan-Xin Yin Jian-Hong Wang Wen-Gang Guo Jing Niu Jie-Lai Xia Zhuo-Li Zhang Andrew C Larson Kai-Chun Wu Dai-Ming Fan Guo-Hong Han | 2014 | World Journal of Gastroenterology2014，20，3： | 26 |
| 12 | Clinicopathologic features, diagnosis and surgical treatment of intrahepatic cholangiocarcinoma in 104 patients显示文摘BACKGROUND: The outcome of surgical treatment of pa- tients with intrahepatic cholangiocarcinoma (ICC) is poor. This study was designed to analyze the relationship between clinicopathologic features and the survival time after opera- tion. METHODS: The operation was performed in 104 patients with mass-forming type ICC at our hospital between No- vember 1996 and May 2000. Seventy-nine patients (76.0%) were followed up successfully. Sixteen clinicopathological variables including age, sex, history of chronic liver di- sease , HBsAg, operation, adjuvant therapy, ascites, lymph node metastasis, invasion of adjacent organs, tumor size, necrosis of tumor, envelope, intrahepatic metastasis, Inter- national Union Against Cancer (UICC) TNM staging, his- tology, and cirrhosis were selected for univariate and multi- variate analyses to evaluate their influence on the prognosis. RESULTS: The accumulative 1-, 3-, 5-year survival rates of the 79 patients were 49.4%, 17.3%, 9.6% respectively. Univariate analysis revealed that sex (P=0.0221), HBsAg (P=0.0115), operation (P=0.0042), adjuvant therapy (P= 0.0389), ascites (P=0.0001), invasion (P=0.0220), intra- hepatic metastasis (P=0.0000) and TNM stage (P= 0.0001) were related to survival time. Multivariate analysis revealed that HBsAg, ascites and TNM stage were signifi- cantly related to prognosis. CONCLUSION: Early diagnosis and treatment and major hepatectomy are essential to improving the results of surgi- cal treatment of ICC patients. | Xiao-Hui Fu, Zhao-Hui Tang, Ming Zong, Guang-Shun Yang, Xiao-Ping Yao and Meng-Chao Wu Shanghai, China Department of Comprehensive Therapy of Hepatobi- liary Tumors, Eastern Hepatobiliary Surgery Hospital, Shanghai 200438, China | 2004 | Hepatobiliary & Pancreatic Diseases International2004，3，2： | 24 |
| 13 | Different regional distribution of SLC25A13 mutations in Chinese patients with neonatal intrahepatic cholestasis显示文摘AIM: To investigate the differences in the mutation spectra of the SLC25A13 gene mutations from specific regions of China. METHODS: Genetic analyses of SLC25A13 mutations were performed in 535 patients with neonatal intrahepatic cholestasis from our center over eight years. Unrelated infants with at least one mutant allele were enrolled to calculate the proportion of SLC25A13 mutations in different regions of China. The boundary between northern and southern China was drawn at the historical border of the Yangtze River.RESULTS: A total of 63 unrelated patients (about 11% of cases with intrahepatic cholestasis) from 16 provinces or municipalities in China had mutations in the SLC25A13 gene, of these 16 (25%) were homozygotes, 28 (44%) were compound heterozygotes and 19 (30%) were heterozygotes. In addition to four well described common mutations (c.851_854del, c.1638_1660dup23, c.615+5G>A and c.1750+72_17514dup17insNM_138459.3:2667 also known as IVS16ins3kb), 13 other mutation types were identified, including three novel mutations: c.985_986insT, c.287T>C and c.1349A>G. According to the geographical division criteria, 60 mutant alleles were identified in patients from the southern areas of China, 43 alleles were identified in patients from the border, and 4 alleles were identified in patients from the northern areas of China. The proportion of four common mutations was higher in south region (56/60, 93%) than that in the border region (34/43, 79%, χ 2 = 4.621, P = 0.032) and the northern region (2/4, 50%, χ 2 = 8.288, P = 0.041). CONCLUSION: The SLC25A13 mutation spectra among the three regions of China were different, providing a basis for the improvement of diagnostic strategies and interpretation of genetic diagnosis. | Rui Chen Xiao-Hong Wang Hai-Yan Fu Shao-Ren Zhang Kuerbanjiang Abudouxikuer Takeyori Saheki Jian-She Wang | 2013 | World Journal of Gastroenterology2013，19，28： | 23 |
| 14 | Targeted puncture of left branch of intrahepatic portal vein in transjugular intrahepatic portosystemic shunt to reduce hepatic encephalopathy显示文摘BACKGROUND Transjugular intrahepatic portosystemic shunt(TIPS) is currently used for the treatment of complications of portal hypertension. The incidence of hepatic encephalopathy(HE) remains a problem in TIPS placement. It has been reported that the right branch mainly receives superior mesenteric venous blood while the left branch mainly receives blood from the splenic vein. We hypothesized that targeted puncture of the left portal vein would divert the non-nutritive blood from the splenic vein into the TIPS shunt; therefore, targeted puncture of the left branch of the intrahepatic portal vein during TIPS may reduce the risk of HE.AIM To evaluate the influence of targeted puncture of left branch of portal vein in TIPS on HE.METHODS A retrospective analysis of 1244 patients with portal-hypertension-related complications of refractory ascites or variceal bleeding who underwent TIPS from January 2000 to January 2013 was performed. Patients were divided into group A(targeting left branch of portal vein, n = 937) and group B(targeting right branch of portal vein, n = 307). TIPS-related HE and clinical outcomes were analyzed.RESULTS The symptoms of ascites and variceal bleeding disappeared within a short time.By the endpoint of follow-up, recurrent bleeding and ascites did not differ significantly between groups A and B(P = 0.278, P = 0.561, respectively).Incidence of HE differed significantly between groups A and B at 1 mo(14.94% vs36.80%, χ~2 = 4.839, P = 0.028), 3 mo(12.48% vs 34.20%, χ~2 = 5.054, P = 0.025), 6 mo(10.03% vs 32.24%, χ~2 = 6.560, P = 0.010), 9 mo(9.17% vs 31.27%, χ~2 = 5.357, P =0.021), and 12 mo(8.21% vs 28.01, χ~2 = 3.848, P = 0.051). There were no significant differences between groups A and B at 3 years(6.61% vs 7.16%, χ~2 = 1.204, P =0.272) and 5 years(5.01% vs 6.18%, χ~2 = 0.072, P = 0.562). The total survival rate did not differ between groups A and B(χ~2 = 0.226, P = 0.634, log-rank test).CONCLUSION Targeted puncture of the left branch of the intrahepatic portal vein during TIPS may reduce the risk of HE but has no direct influence on prognosis of portalhypertension-related complications. | Shi-Hua Luo Jian-Guo Chu He Huang Guo-Rui Zhao Ke-Chun Yao | 2019 | World Journal of Gastroenterology2019，25，9： | 22 |
| 15 | Preoperative differential diagnosis between intrahepatic biliary cystadenoma and cystadenocarcinoma:A single-center experience显示文摘AIM:To investigate preoperative differential diagnoses made between intrahepatic biliary cystadenoma and intrahepatic biliary cystadenocarcinoma.METHODS:A retrospective analysis of patient data was performed,which included 21 cases of intrahepatic biliary cystadenoma and 25 cases of intrahepatic biliary cystadenocarcinoma diagnosed between April 2003and April 2013 at the General Hospital of PLA.Potential patients were excluded whose diagnoses were not confirmed pathologically.Basic information(including patient age and gender),clinical manifestation,duration of symptoms,serum assay results(including tumor markers and the results of liver function tests),radiological features and pathological results were collected.All patients were followed up.RESULTS:Preoperative levels of cancer antigen 125(12.51±9.31 vs 23.20±21.86,P<0.05)and carbohydrate antigen 19-9(22.56±26.30 vs 72.55±115.99,P<0.05)were higher in the cystadenocarcinoma subgroup than in the cystadenoma subgroup.There were no statistically significant differences in age or gender between the two groups,or in pre-or post-operative levels of alanine aminotransferase,aspartate aminotransferase,total bilirubin(TBIL),and direct bilirubin(DBIL)between the two groups.However,eight of the 21 patients with cystadenoma and six of the 25 patients with cystadenocarcinoma had elevated levels of TBIL and DBIL.There were three cases in the cystadenoma subgroup and six cases in the cystadenocarcinoma subgroup with postoperative complications.CONCLUSION:Preoperative differential diagnosis relies on the integration of information,including clinical symptoms,laboratory findings and imaging results. | Fu-Bo Zhang Ai-Min Zhang Zhi-Bin Zhang Xin Huang Xi-Tao Wang Jia-Hong Dong | 2014 | World Journal of Gastroenterology2014，20，35： | 22 |
| 16 | Risk factors of intrahepatic cholangiocarcinoma in patients with hepatolithiasis:a case-control study显示文摘BACKGROUND:Why 3.3% to 10% of all patients with hepatolithiasis develop intrahepatic cholangiocarcinoma (ICC) remains unknown.We carried out a hospital-based case-control study to identify risk factors for the development of ICC in patients with hepatolithiasis in China.METHODS:Eighty-seven patients with pathologically diagnosed hepatolithiasis associated with ICC and 228 with hepatolithiasis alone matched by sex,age (±2 years),hospital admittance and place of residence were interviewed during the period of 2000-2008.Odds ratios (OR) and 95% confidence intervals (CI) were calculated for each risk factor.RESULTS:Among the patients with hepatolithiasis associated with ICC,the mean age was 57.7 years and 61.0% were female Univariate analysis showed that the significant risk factors for ICC development in hepatolithiasis were smoking,family history of cancer,appendectomy during childhood (under age 20),and duration of symptoms >10 years.In multivariate stepwise logistic regression analysis,smoking (OR=1.931,95% CI:1.000-3.731),family history of cancer (OR=5.175,95% CI:1.216-22.022),and duration of symptoms >10 years (OR=2.348 95% CI:1.394-3.952) were independent factors.CONCLUSION:Smoking,family history of cancer and duration of symptoms >10 years may be risk factors for ICC in patients with hepatolithiasis. | Zhen-Yu Liu,Yan-Ming Zhou,Le-Hua Shi and Zheng-Feng YinAuthor Affiliations:Molecular Oncology Laboratory and Department of Comprehensive Treatment I,Eastern Hepatobiliary Surgery Hospital,Second Military Medical University,Shanghai 200438,China Department of Hepato-Biliary-Pancreato-Vascular Surgery,First Affiliated Hospital,Xiamen University,Xiamen 361003,China | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，6： | 21 |
| 17 | Risk factors associated with early and late recurrence after curative resection of hepatocellular carcinoma: a single institution's experience with 398 consecutive patients显示文摘BACKGROUND: Surgical resection is an important curative treatment for hepatocellular carcinoma (HCC); however, some patients experience an unexpected recurrence even after hepatectomy. The present study aimed to investigate risk factors and predictive criteria for early and late recurrence of HCC after resection.METHODS: A retrospective analysis of 398 Chinese patients who received curative resection for HCC was conducted. Patients were divided into three groups: without recurrence, early recurrence and late recurrence. Prognostic factors and predictive criteria for early and late recurrence were statistically analyzed. RESULTS: The cumulative recurrence-free survival rates at1, 2, 3, 4, and 5 years were 75.5%, 58.2%, 54.1%, 40.5%, and28.7%, respectively. The distribution of the time to recurrence suggested that recurrence could be divided into early phase(before 2 years; n=164) and late phase (after 2 years; n=83)Cox's multivariate proportional hazard model analysis revealed that multiplicity of tumors (P=0.004) and venous infiltration(P=0.002) were independent risk factors associated with early recurrence. In contrast, indocyanine green retention rate at 15minutes (P=0.007), serum albumin level (P=0.045), and HBeAg status ( =0.028) proved to be significant independent adverse prognostic factors for late recurrence. Patients with at least 1of the 2 early recurrence risk factors (multiplicity of tumors ≥2and venous infiltration) or with 2 or more late recurrence risk factors are often susceptible to recurrence (P=1.36e-4 and 1.0e-6respectively).CONCLUSIONS: Early and late recurrences correlate with different risk factors and predictive criteria. Early recurrence primarily results from intrahepatic metastases, while late recurrence may be multicentric in origin. | Zheng-Gui Du Yong-Gang Wei Ke-Fei Chen Bo Li | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，2： | 20 |
| 18 | Surgical treatment of intra hepatic recurrence of hepatocellular carcinoma显示文摘Recurrence after hepatocellular carcinoma(HCC) is frequent.Currently,there are no recommendations on therapeutic strategy after recurrence of HCC.Whereas the 5 year-recurrence rate after resection of HCC is 100%,this drops to 15% after primary liver transplantation.Repeat hepatectomy and salvage liver transplantation(SLT) could be performed in selected patients to treat recurrent HCC and enable prolonged overall survival after treatment of recurrence.Other therapies such as local ablation,chemoembolization or sorafenib could be proposed to those patients unable to benefit from resection or SLT.A clear definition of the place of SLT and 'prophylactic' liver transplantation is required.Indeed,identifying risks factors for recurrence at time of primary liver resection of HCC may help to avoid recurrence beyond Milan criteria and non-resectable situations.In this review,we summarize the recent data available in the literature on the feasibility and outcomes of repeat hepatectomy and SLT as treatment for recurrent HCC. | Laurence Lacaze Michel Scotté | 2015 | World Journal of Hepatology2015，7，13： | 19 |
| 19 | Transjugular Intrahepatic Portosystemic Shunt Versus Surgical Shunting in the Management of Portal Hypertension显示文摘Background: The purpose of this article was to clarify the optimal management concerning transjugular intrahepatic portosystemic shunts (TIPSs) and surgical shunting in treating portal hypertension. Methods: All databases, including CBM, CNKI, WFPD, Medline, EMBASE, PubMed and Cochrane up to February 2014, were searched for randomized controlled trials (RCTs) comparing TIPS with surgical shunting. Four RCTs, which were extracted by two independent investigators and were evaluated in postoperative complications, mortality, 2- and 5-year survival, hospital stay, operating time and hospitalization charges. Results: The morbidity in variceal rehemorrhage was significantly higher in TIPS than in surgical shunts (odds ratio [OR] = 7.45, 95% confidence interval[C/]: (3.93-14.15), P 〈 0.00001), the same outcomes were seen in shunt stenosis (OR = 20.01,95% CI: (6.67-59.99), P 〈 0.000001 ) and in hepatic encephalopathy (OR = 2.50, 95% CI: (1.63-3.84), P 〈 0.0001 ). Significantly better 2-year survival (OR = 0.66; 95% CI: (0.44-0.98), P ~ 0.04) and 5-year survival (OR = 0.44; 95% CI: (0.30-0.66), P 〈 0.00001) were seen in patients undergoing surgical shunting compared with TIPS. Conclusions: Compared with TIPS, postoperative complications and survival after surgical shunting were superior for patients with portal hypertension. Application of surgical shunting was recommended for patients rather than TIPS. | Long Huang Qing-Sheng Yu Qi Zhang Ju-Da Liu Zhen Wang | 2015 | Chinese Medical Journal2015，，6： | 17 |
| 20 | contrast enhanced computed tomography and reconstruction of hepatic vascular system for transjugular intrahepatic portal systemic shunt puncture path planning显示文摘AIM: To describe a method for the transjugular intrahepatic portal systemic shunt(TIPS) placement performed with the aid of contrast-enhanced computed tomography(CECT) and three-dimensional reconstructed vascular images(3D RVIs), and to assess its safety and effectiveness. METHODS: Four hundred and ninety patients were treated with TIPS between January 2005 and December 2012. All patients underwent liver CECT and reconstruction of 3D RVIs of the right hepatic vein to portal vein(PV) prior to the operation. The 3D RVIs were carefully reviewed to plan the puncture path fromthe start to target points for needle pass through the PV in the TIPS procedure. R E S U LTS :The improved TIPS procedure was successful in 483(98.6%) of the 490 patients. The number of punctures attempted was one in 294(60%) patients, 2 to 3 in 147(30%) patients, 4 to 6 in 25(5.1%) patients and more than 6 in 17(3.5%) patients. Seven patients failed. Of the 490 patients, 12 had punctures into the artery, 15 into the bile duct, eight into the gallbladder, and 18 through the liver capsule. Analysis of the portograms from the 483 successful cases indicated that the puncture points were all located distally to the PV bifurcation on anteroposterior images, while the points were located proximally to the bifurcation in the three cases with intraabdominal bleeding. The complications included three cases of bleeding, of whom one died and two needed surgery. CONCLUSION: Use of CECT and 3D RVIs to plan the puncture path for TIPS procedure is safe, simple and effective for clinical use. | Jian-Ping Qin Shan-Hong Tang Ming-De Jiang Qian-Wen He Hong-Bin Chen Xin Yao Wei-Zheng Zeng Ming Gu | 2015 | World Journal of Gastroenterology2015，21，32： | 17 |
