The aim of this study is the assessment of the relative arterial and venous contribution to the total liver blood flow (hepatic perfusion index-HPI), with two methods (S1 and S2), and estimation of their value. With this correction, HPI nonsignificantly increases (p>0.05) in all the groups of patients, with a very high correlation between the HPI(S1) and HPI(S2) values (p<0.01). In comparison to the portal perfusion in controls, values were significantly (p<0,01) lower in chronic active hepatitis and liver cirrhosis and differed between themselves (p<0.01). In the groups of cirrhotic patients with esophageal varices, sclerosated esophageal varices, recanalized umbilical vein, portal thrombosis and cavernous portal vein, portal perfusion was lower (p<0.01) than in controls, chronic active hepatitis and liver cirrhosis without collaterals. Both angioscintigraphic methods are useful for the estimation of the disturbances in the portal system. Because of the more exact estimation of the liver perfusion, S2 is recommended.

BACKGROUND: Many noninvasive surrogate marker for Portal hypertension or for the presence or grade of esophageal varices were studied..Splenomegaly along with splenic congestion secondary to splenic hyperdynamic circulation is seen secondary to Portal hypertension in cirrhotic patients that can be quantified by elastography. AIM:The aim of this study was to investigate whether spleen stiffness, assessed by TE, useful tool for grading chronic liver diseases and to compare its performance in predicting the presence and size of esophageal varices in liver cirrhosis patients. METHODOLOGY:86 patients with cirrhosis and 80 controls underwent transient elastography of liver and spleen for the assessment of liver stiffness (LSM) and spleen stiffness (SSM) . Upper GI endoscopy done in all Cirrhotic patients. RESULTS: Spleen stiffness showed higher values in liver cirrhosis patients as compared with controls: 58.2 kpa vs14.8 kpa (P < 0.0001) and also found to be significantly higher in cirrhotic patients compared with varices and those without varices (69.01 vs 42.05 kpa, P < 0.0001). Liver stiffness was also found to be higher in cirrhotic patients with varices when compared to patients without varices (38.5vs 21.2 kpa). Using both liver and spleen stiffness measurement we can predicted the presence of esophageal varices correctly. CONCLUSION: Spleen stiffness can be assessed using transient elastography, higher value correlated well with liver cirrhosis and presence of esophageal varices although it couldn’t correlate with grade of Esophageal Varix. Combined assessment of spleen and liver stiffness had better prediction of presence of Esophageal Varix.

Background and Study Aims: Portal hypertension is one of the most important complications of liver cirrhosis. The prevalence of varices among cirrhotic patients is variable. Therefore, endoscopic screening of all patients with liver cirrhosis would result in a large number of unnecessary additional burdens to endoscopic units. Our aim was to assess the diagnostic accuracy of spleen stiffness measured by transient elastography (Fibroscan) for prediction of the presence of varices in patients with hepatitis C related cirrhosis. Patients and Methods: The study was carried out on 100 patients with HCV-induced cirrhosis and were divided into 2 groups according to presence or absence of varices by Esophago-gastro-duodenoscopy: Group I: patients with HCV-induced cirrhosis with varices; Group II: patients with HCV-induced cirrhosis without varices. Clinical and laboratory parameters, andominal ultrasonography, Upper gastrointestinal endoscopy and transient elastography to assess the liver and spleen stiffness were carried out to all studied persons. Results: Spleen stiffness had significant diagnostic value to differentiate between cirrhotic patients with varices and cirrhotic patients without varices , it had significant diagnostic value in presence of esophageal varices at cut-off (≥46.4 K Pascal) the sensitivity for detection of esophageal varices was 93%, specificity 100%, positive predictive value (PPV) was 80%, negative predictive value (NPV) was 100%; accuracy was 95% and area under the curve was 0.98 denoting that spleen stiffness is a good predictor of esophageal varices. Conclusion: Spleen stiffness was considered as an excellent predictor of esophageal varices and better than liver stiffness in prediction of esophageal varices presence and had significant diagnostic value to differentiate between the patients with varices and patients without varices at cut off (≥46.4 K Pascal) and it may have a role in variceal grading.

Abstract Background Bleeding esophageal varices is a deadly complication of liver cirrhosis. Guidelines recommend an early diagnosis of esophageal varices before incident bleeding by screening all patients diagnosed with liver cirrhosis. Though it has been reported elsewhere that the presence of esophageal varices varies widely among cirrhotic patients this has not been assessed in Tanzania since endoscopy is not readily available for routine use in our setting. This study was designed to determine the prevalence of esophageal varices and assess the utility of clinical parameters in predicting the presence of varices among cirrhotic patients in northwestern Tanzania. Methods A cross-sectional analysis of adult patients with liver cirrhosis was done at Bugando Medical Centre. Demographic, clinical, laboratory and endoscopic data were collected and analyzed using STATA 13. The presence of esophageal varices was detected using endoscopic examination and associated factors were assessed by logistic regression. The predictive value of clinical predictors was also assessed by calculating sensitivity and specificity. Results A total of 223 patients were enrolled, where 88 (39.5%; 95%CI: 33.0–45.9) had esophageal varices. The varices were independently associated with increased age (OR: 1.02; 95%CI: 1.0–1.04; p = 0.030); increased splenic diameter (OR:1.3; 95%CI:1.2–1.5; p <  0.001), increased portal vein diameter (OR:1.2; 95%CI: 1.07–1.4; p = 0.003), having ascites (OR: 3.0; 95%CI: 1.01–8.7; p = 0.046), and advanced liver disease (OR: 2.9; 95%CI: 1.3–6.7; p = 0.008). PSDR least performed in predicting varices, (AUC: 0.382; 95%CI: 0.304–0.459; cutoff: < 640; Sensitivity: 58.0%; 95%CI: 46.9–68.4; specificity: 57.0%; 95%CI: 48.2–65.5). SPD had better prediction; (AUC: 0.713; 95%CI: 0.646–0.781; cut off: > 15.2 cm; sensitivity: 65.9%; (95% CI: 55–75.7 and specificity:65.2%; 95%CI: 56.5–73.2), followed by PVD, (AUC: 0.6392; 95%CI: 0.566–0.712;cutoff: > 1.45 cm; sensitivity: 62.5%; 95CI: 51.5–72.6; specificity: 61.5%; 95%CI: 52.7–69.7). Conclusion Esophageal varices were prevalent among cirrhotic patients, most of which were at risk of bleeding. The non-invasive prediction of varices was not strong enough to replace endoscopic diagnosis. However, the predictors in this study can potentially assist in the selection of patients at high risk of having varices and prioritize them for endoscopic screening and appropriate management.

Bleeding Episodes

Coagulation abnormalities are among the number of potential risk factors toinitiate the bleeding episodes from gastrcr-esophageal varices in liver cirrhosis. The impairment of liver clearance of activated coagulation factors, the release of thromboplastin-like activity from the necrotic liver cells and the hemodynamic changes due to expanded bollaterals may all contribute to activate the coagulation cascade.However, little is known about the mechanisms leading to this activation. Activated Factor VII (FVIIa) is known totrigger both intrinsec and extrinsec coagulation pathway. Therefore, we measured FVIIa in a group of 33 cirrhotic patients in order to see if a difference between bleeders and non-bleeders patients would correlate with Factor VII activation. The patients were divided in two groups according to the presence or the absence of major bleeding from gastroesophageal varices; haemorragic episodes were confirmed by a gastroscopic examination performed during or immediately after bleeding episodes. Factor VII coagulant assay (VII:C - one stage clotting method) and Factor VII coupled amidolytic assay (VII:CHR) were performed and a factor VII activity ratio (VIIa) was calculated as VII:C/VII:CHR. The results (mean ± S.E.) are summarized in this table:No difference in Vila distribution was seen when the patients were divided on the base of liver impairment (according to Child’s criteria) .Our study shows that FVII activation is related to bleeding from esophageal varices but not to the degree of liver impairment and strongly suggests the existence of an hypercoagulable state in liver cirrhosis, probably related to major bleeding from gastroesophageal varices in cirrhotic patients.

Aims: Non-invasive methods are required to diagnose presence and grading of esophageal varices in patients with he- patic cirrhosis and in this respect we have evaluated the role of transient elastography and abdominal ultrasound parameters. Material and methods: Cirrhotic patients were prospectively evaluated by transient elastography and Doppler ultrasound for diagnosis of presence and grading of esophageal varices, the results being compared with the findings of the esophagogas- troduodenoscopy. Results: Sixty patients with hepatic cirrhosis were analysed. The parameters that reached statistical signifi- cance for diagnosis of esophageal varices were: liver stiffness (LSM) > 15 kPa, hemodynamic liver index (PVr1) ≥ 0.66, portal vascular resistance (PVR) > 17.66 and splenoportal index (SPI) > 4.77. The only parameter that reached statistical power for the diagnosis of large esophageal varices was LSM at a cut-off value of 28.8 kPa. Conclusions: Assessment of LSM in patients with liver cirrhosis can predict both the presence of esophageal varices and of large esophageal varices. The PVr1, PVR and SPI Doppler indexes can be used to diagnose the presence of esophageal varices but have no role in the prediction of large esophageal varices. Further studies are required to confirm these results and offer a stronger clinical significance.

Objective: to evaluate the prospects and role of the methods of imaging (ultrasound and CT) in the diagnosis of the pathogenic aspects of the development and correction of portal hypertension in liver cirrhosis. Material and methods. Patients with liver cirrhosis and portal hypertension, Doppler ultrasound, multislice computed tomography. Conclusion. The combined use of ultrasound and computed tomography facilitates tracing of the dynamics of the disclosure of portocaval anastomoses and predict the course of liver cirrhosis and portal hypertension. The application of the integrated ultrasound to determine the rate of blood flow volume in vessels of portal system and portocaval anastomosis will enable development of differential diagnostic criteria for the early diagnosis of portal hypertension. The detection of recanalized umbilical vein by means of 3D-visualization of its anatomy makes it possible to use it for delivering of therapeutic agents to the liver in its pathology.

AbstractIntroduction: Portal hypertension results from increased resistance to the portal blood flow. The ultrasound represents a noninvasive tool for assessing the structural and hemodynamic abnormalities in this condition.Objectives: The assessment of the hemodynamic blood flow of the liver and spleen by using Doppler ultrasound in patients with portal hypertension compared with healthy subjects and to identify correlations with the severity of liver cirrhosis and esophageal varices.Materials and Method: This study included 50 patients with liver cirrhosis and 20 healthy subjects as controls. Different correlations were carried out between hemodynamic variables obtained from the Doppler examination and the severity of cirrhosis as assessed by the Child score and the degree of esophageal varices at endoscopy.Results: The portal vein diameter was larger in cirrhotic patients compared with the control group. The mean portal vein velocity and the blood flow were significantly lower in advanced forms of liver cirrhosis. The portal vein congestion index, the pulsatility and resistivity indexes of the hepatic artery were significantly increased in patients with CHILD B and C cirrhosis compared with the control group and patients in CHILD class A. There were no statistically significant differences between the pulsatility and resistivity indexes of the splenic artery in patients with cirrhosis. The liver vascular index was significantly lower in patients with advanced cirrhosis.Conclusions: The ultrasound is a valuable noninvasive tool for cirrhotic patients with portal hypertension. However, it is not sufficiently accurate in differentiating between different classes of cirrhosis or degrees of esophageal varices.

Abstract Background: The goal of this study was to determine the diagnostic performance of in vivo quantitative proton magnetic resonance spectroscopy (1H-MRS) to identify the presence of esophageal varices needing treatment (VNT), as well as to investigate its correlation with clinical variables in patients with liver cirrhosis. Methods: Forty cirrhotic patients without VNT showing negative red color sign, and 40 cirrhotic patients with VNT showing positive red color sign underwent laboratory tests, esophago-gastro-duodenoscopy, and 1H-MRS with single-voxel localization in cirrhotic liver parenchyma. Results: The levels of lactate+triglyceride (TG) and choline in cirrhotic patients with VNT were significantly higher than those of cirrhotic patients without VNT. Lactate+TG and choline levels were positively correlated with spleen diameter and negatively correlated with platelet count in the combined group of cirrhotic patients with and without VNT. In cirrhotic patients with VNT, older age, longer spleen diameter, lower platelet counts, and lower ratios of platelet count/spleen diameter were independently associated with an increase of lactate+TG and choline metabolites in the presence of esophageal VNT. Additionally, the area under the curve used to distinguish cirrhotic liver with VNT from cirrhotic liver without VNT was 1.00 (95% confidence interval [CI]: 0.95–1.00) for lactate+TG and 0.67 (95% CI 0.55–0.77) for choline. Conclusions: Our study demonstrated that higher hepatic lactate+TG and choline levels in cirrhotic patients in conjunction with longer spleen diameter, lower platelet counts, and lower ratios of platelet count to spleen diameter were associated with the presence of esophageal VNT and the risk of developing variceal bleeding. Therefore, in vivo, 1H-MRS may be an effective tool for diagnosing and predicting esophageal VNT in patients with liver cirrhosis.
