Objective The usefulness of measurement of nuclear DNA content elevation for diagnosis of early hepatocellular carcinoma was evaluated by a study of 186 patients with liver cirrhosis. Methods Nuclear DNA content was measured using an automatic image analysis system.Results ①Hepatocellular carcinoma was found in 37 patients during 10 years follow-up, the cumulative incidence of hepatocellular carcinoma was 19.89%. ②The incidence of hepatocellular carcinoma increased with the increase of the patterns of α-fetoprotein (AFP), 5c exceeding rate (5cER), FORM PE, but positive predictive value of 5cER was the highest of three parameters, the difference among all groups was significant by the χ2 test (Ｐ＜0.05). ③When 5cER joined AFP for monitoring development of hepatocellular carcinoma, the incidence of hepatocellular carcinoma was 72.00%, which was significantly higher than that of 5cER or AFP alone, the difference between groups was highly significant (Ｐ＜0.01). Conclusion Patients who had 5cER levels of 3%-5% or more, who had transient increases in 5cER or who had both, should be treated as being in a super-highrisk group for hepatocellular carcinoma. Frequent and careful examination by ultrasonography of such patients is recommended. It is important that measurement of 5cER join with AFP in cirrhotic patients monitored for early development of hepatocellular carcinoma.
Objective To compare the difference of the changes of platelet counts after splenectomy between the patients with splenic rupture and patients with cirrhosis and portal hypertension, and to analyze the possible reasons and clinical significance. Methods The platelet count of 47 splenic rupture patients and 36 cirrhosis patients who had been carried out splenectomy from July 2008 to December 2009 in our hospital were counted, and the differences in platelet count and it’s change tendency of two groups were compared. Results In the splenic rupture group，the platelet count of all 47 patients increased abnormally after operation, the maxlmum value of platelet count among 300×109/L-600×109/L in 6 cases，600×109/L-900×109/L in 21 cases，and above 900×109/L in 20 cases. In the cirrhosis group，the maxlmum value of platelet count after operation was above 300×109/L in 26 cases，100×109/L-300×109/L in 8 cases，and below 100×109/L in 2 cases. The difference of maxlmum value of platelet count in the two groups had statistic significance（P=0.00）. Compared with the cirrhosis group, the platelet count increased more significant and decreased more slow in splenic rupture group（P＜0.05）.The abnormal days and rising range of platelet count were higher in patient with Child A than Child B and C（P=0.006，P=0.002）. Conclusions The change of platelet count after operation in splenic rupture group was obviously different from cirrhosis group because of the difference of the liver function and body situation of patients. To patients with splenic rupture or cirrhosis, appropriate treatment based on the platelet count and liver function could obtain good therapeutic effect.
ObjectiveTo investigate the hotspots and frontiers and to reveal research trends of cirrhosis with portal vein thrombosis (PVT) by visual analysis.MethodsWe explored the distributions, key citations and research trends of articles on cirrhosis with PVT published from 1991 to 2020 by citation analysis, co-word analysis, and burst detection by information visual software CiteSpace.ResultsThe quantity of articles on cirrhosis with PVT had been increasing over time. The management of PVT remained the hotspots, while the efficacy and prognosis of anticoagulation of PVT as well as the risk factors and underlying mechanisms of PVT had been frontiers in recent years.ConclusionsAnticoagulation and risk factors have been hotspots and frontiers in recent years.
ObjectivesTo systematically review the efficacy of laparoscopic hepatectomy (LH) and open hepatectomy (OH) on the hepatocellular carcinoma patients with cirrhosis.MethodsPubMed, EMbase, Web of Science, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases were searched online to collect the cohort studies of LHvs.OH on hepatocellular carcinoma patients with cirrhosis from inception to November 31st, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 15 cohort studies involving 1 720 patients were included. The results of meta-analysis showed that: compared with OH, LH had less blood loss (MD=–226.94, 95%CI –339.87 to –114.01, P<0.000 1), lower transfusion rate (OR=0.48, 95%CI 0.27 to 0.83,P=0.009), less occurrence of complications (OR=0.32, 95%CI 0.23 to 0.45, P<0.000 01), shorter postoperative hospital stay (MD=–3.66, 95%CI –5.19 to –2.14,P<0.000 01), lower mortality rate (OR=0.47, 95%CI 0.24 to 0.92,P=0.03), wider surgical margin (OR=0.78, 95%CI 0.20 to 1.36, P=0.009), higher 1, 3 and 5-year survival rate (OR=2.47, 95%CI 1.35 to 4.51, P=0.003; OR=1.62, 95%CI 1.11 to 2.36, P=0.01; OR=1.58, 95%CI 1.19 to 2.10, P=0.002, respectively) and 1-year disease free survival rate (OR=1.69, 95%CI=1.20 to 2.39, P=0.003). There were no significant differences in operation time (MD=28.64, 95%CI –7.53 to 64.82, P=0.12), tumor size (MD=–0.37, 95%CI –0.75 to 0.02, P=0.06), 3-year disease free survival rate (OR=1.14, 95%CI 0.86 to 1.51, P=0.36) and 5-year disease free survival rate (OR=0.99, 95%CI 0.77 to 1.28, P=0.97) between the two groups.ConclusionsThe perioperation and short-term postoperative outcomes of LH are significant in HCC patients with cirrhosis, and which have good long-term prognosis. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To investigate the efficacy and safety of abdominal indwelling catheterization for the patients with large-volume ascites. Methods A total of 84 patients with liver cirrhosis complicated with large-volume ascites admitted in the first affiliated hospital of Xi’an Jiaotong University from January 2015 to December 2015 were retrospectively analyzed. Patients were divided into two groups, one was the puncture group and another was the catheterization group. The efficacy and safety were evaluated. Results Forty-four patients were enrolled in catheterization group, whereas forty patients were enrolled in puncture group. Symptoms associated with ascites had been eased and patients’ qualities of life had been improved in 2 weeks in each group. The tube fell out rate was 27.3% for patients in catheterization group. There was no operation related complications such as death, bleeding and intestinal perforation occurred. Either Child B stage or Child C stage, the dynamic changes of liver function and renal function in catheterization group were comparable to those in puncture group. No adverse event such as catheterization-related or puncture-related infection was observed. Conclusion Abdominal catheterization is effective and safe in management of large amount of ascites complicated with cirrhosis, however, the high rate of tube-fell-out should be paid more attention.
ObjectiveTo explore an individualized treatment program to prevent the initial bleeding of a patient with cirrhosis and esophageal varices by the methods of evidence-based medicine. MethodsOne patient with cirrhosis and esophageal varices was admitted into our hospital on November 2, 2013. After evaluating the patient's condition adequately, we proposed the problem according to the PICOS principles. Then, we assessed the clinical evidence from the Cochrane Library (1990-2012), Medline (1950-2012), Embase (1991-2012), VIP (1989-2013), and CBM (1990-2013). The individualized treatment plan was made through doctors' experiences and analysis of those high-quality evidences from the databases. ResultsEight studies (randomized controlled trials and 5 meta-analysis) were included. We evaluated a series of associated problems:whether we should take measurement to prevent initial bleeding of esophageal varices; which one (β-blockers or ligation of esophageal varices) was the best method to prevent the initial bleeding based on efficacy, complication and cost-effectiveness. Then, according to the evidences and the patient's view, we gave non-selectiveβ-blocker as the primary prevention. After one-year followed-up, the initial bleeding of the patient did not occur. ConclusionMaking the prevention plan for a patient with cirrhosis and esophageal varices can not only find out the individualized program, but also push the patient to make decision for their own health.
The aim of this study is to assess ischemia/reperfusion injury in carbon tetrachloride induced cirrhotic liver as compared to normal liver in the rats. Results showed that in cirrhotic liver, instead of diminishing the hepatic vein nitric oxide level increased significantly after ischemia from 8.04 μmol/L to 11.52 μmol/L and remained high till 5 hrs after reperfusion. The hepatic adenosine triphosphate (ATP) contents decreased as that seen in normal rat but did not restore to normal till the end of 5 hrs after reperfusion. Based on these findings, it is postulated that in cirrhotic liver, ischemia/reperfusion injury is aggrvated as evidenced by of nitric oxide, and extended diminishing in ATP.
Twelve patients with multiple vavices were found adjacent to the common bile duct during cholecystectomy and exploration of the common blie duct in the presence of stones. Eleven of them were with cirrhosis. The authors recommend that retrograde cholecystecotomy, or partial cholecystestomy with electrical cauterization of the remaining gallbladder mucosa ,or even cholecystostomy be the optimal selection in the presence of a large venous channel in calot’s triangle. Multiple fine-needle puncture of the bile duct can be performed over the vascullar area until bile is aspirated; extracting the choledocholith from a transduodenal sphincterotomy is another selective maneuver; and if bleeding occurs, suturing for hemostasis can be placed on the connective tissue over both sides of the lacerated vessel instead of the wall of varices.
ObjectiveTo investigate impact of splenectomy plus pericardial devascularization on liver hemodynamics and liver function for liver cirrhosis patients with portal hypertension. MethodsThe internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of portal vein and hepatic artery of 42 cases of liver cirrhosis with portal hypertension were measured by Doppler ultrasonic instrument on day 1 before operation and on day 7 after operation. The free portal pressures at different phases (after open abdomen, after splenic artery ligation, after splenectomy, and after devasculanrization) were read from the disposable pressure sensor. Twenty-four healthy people through physical examination were selected as control. Results① The free portal pressure of liver cirrhosis patients with portal hypertension was decreased from (29.12±1.40) mm Hg after open abdomen to (22.71±1.21) mm Hg after splenic artery ligation, and further decreased to (21.32±1.12) mm Hg after splenectomy, but increased to (22.42±1.15) mm Hg after devasculanrization, the difference was statisticly different (all P < 0.01). ② Compared with the healthy people, for the liver cirrhosis patients with portal hypertension, the internal diameter, maximum velocity, minimum velocity, and flow volume of portal vein were significantly enlarged (all P < 0.01), which of hepatic artery were significantly reduced (all P < 0.01) on day 1 before operation; On day 7 after operation, the internal diameter of portal vein was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, and mean velocity of portal vein were significantly enlarged (all P < 0.01), but the internal diameter of hepatic artery was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01). For the liver cirrhosis patients with portal hypertension, compared with the values on day 1 before operation, the internal diameter and the flow volume of portal vein were significantly reduced (all P < 0.01) on day 7 after operation; the internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01) on day 7 after operation. ③ The Child-Pugh classification of liver function between before and after surgery had no significant difference (χ2=1.050, P > 0.05). ④ No death and no hepatic encephalopathy occurred, no thrombosis of splenic vein or portal vein was observed on day 7 after surgery. Conclusionsplenectomy plus pericardial devascularization could decrease portal vein pressure and reduce blood flow of portal vein, while increase blood flow of hepatic artery, it doesn't affect liver function.
Objective To study the expression of proapoptosis gene bax in hepatocellular carcinoma (HCC) and its clinical significance.Methods The protein expression levels of bax were determined by immunohistochemistry with Envision system; bax mRNA was detected by in situ hybridizition. Results Using immunohistochemistry and in situ hybridizition method, bax protein was detectable in 47.50% of HCC and in 78.57% of cirrhosis (Ｐ＜0.05); there was significant relationship between bax expression and grades of differentiation, between bax expression and clinical stages, and between bax expression and AFP levels (Ｐ＜0.05, Ｐ＜0.01, respectively). However, they were no statistical difference between the male and female or the old and young patient (Ｐ＞0.05, respectively). The expression of bax mRNA by in situ hybridizition were corresponding to immunohistochemistry, and there were no statistical difference between them. Conclusion Proapoptotic gene bax participates partially apoptosis regulation in HCC, the expressions show some correlation with grades, clinical stages and levels of AFP.
