    ABSTRACT: To investigate the predictive value of hepatic venous pressure gradient (HVPG) for early bleeding after esophageal variceal ligation (EVL) by analyzing the differences in HVPG in patients with and without post-EVL bleeding. The medical records of patients who had been diagnosed with cirrhosis and esophageal varices and who had pre-EVL HVPG measurement data were surveyed. The study population included 105 patients from October 2010 to March 2014. Data of HVPG value, previous treatment history, endoscopic manifestation, and whether bleeding and serious complications occurred within 2 weeks after the ligation procedure were investigated as independent risk factors.Statistical METHODS: included the chi-square test and Wilcoxon test, logistic regression modeling and receiver operating characteristic (ROC) analysis using the SPSS software version 16. Only HVPG value was identified as an independent risk factor of early bleeding after EVL.According to the ROC analysis, the area under the curve (AUC) of HVPG for early bleeding after EVL was 0.866; when HVPG was more than or equal to 16 mmHg, AUC was 0.838. The sensitivity was 90.9% and the specificity was 76.4%. HVPG is an independent factor of early bleeding after EVL and when HVPG cut-off value of more than or equal to 16 mmHg is used the predictive ability has certain accuracy and high sensitivity and specificity.

    ABSTRACT: Although the therapy of varices in liver cirrhosis has improved, the mortality during a variceal hemorrhage episode remains high. Patients with hepatic venous pressure gradient (HVPG) greater than 12 mmHg have been identified as being at a higher risk for the first hemorrhage episode. The aim of this study was to find an accurate method to predict HVPG greater than 12 mmHg. A total of 150 hepatitis B patients with liver cirrhosis were enrolled and analyzed retrospectively. The patients were randomly divided into the experiment group and the validation group. The experiment group was used to construct a model to predict HVPG greater than 12 mmHg. The validation group was used to verify the predictive equation. The predictive model combined with the liver/spleen volume ratio and classification of varices was constructed to predict HVPG greater than 12 mmHg. The area under the curve of this predictive equation was 0.919. The values of sensitivity, specificity, positive predictive value, and negative predictive value were 92.9, 87.0, 89.7, and 90.9%, respectively. The following equation was used to calculate the HVPG score: \eqalignno{ {\hskip-12pt\rm HVPG}\,{\rm score}={\rm 13}.{\rm 651}-{\rm 6}.{\rm 187}{\times}{\rm ln}\,\left( {{\rm liver}/{\rm spleen}\,{\rm volume}} \right){\plus}\cr &{\hskip-19.2pc{\rm 2}.{\rm 755}\cr &{\times}\left[ {{\rm classification}\,{\rm of}\,{\rm varices} \cr & {\ \rm score}\cr & \,\left( {{\rm classification}\,{\rm of}\,{\hskip-1pt{\vskip-6pt{\rm varices:}\,{\rm small,}\,{\rm 1;}\,{\rm large,}\,{\rm 2}{\vskip-6pt} \right)} {\vskip-6pt\right]. \cr} CONCLUSION: The new model combining the liver/spleen volume ratio and classification of varices can accurately predict HVPG in hepatitis B patients with cirrhosis.

    ABSTRACT: To investigate the risk factors for 6-wk rebleeding and mortality in acute variceal hemorrhage (AVH) patients treated by percutaneous transhepatic variceal embolization (PTVE). A retrospective cohort study of AVH patients who had undergone PTVE treatment was conducted between January 2010 and December 2012. Demographic information, medical histories, physical examination findings, and laboratory test results were collected. The PTVE procedure was performed as a rescue therapy for patients who failed endoscopic and pharmacologic treatment. Survival analysis was estimated using the Kaplan-Meier method and compared using the log-rank test. The multivariate analysis was performed using the Cox regression test to identify independent risk factors for rebleeding and mortality. One hundred and one patients were included; 71 were males and the average age was 51 years. Twenty-one patients rebled within 6 wk. Patients with high-risk stigmata, PTVE with trunk obliteration, and a hepatic vein pressure gradient (HVPG) ≥ 20 mmHg were at increased risk for rebleeding (OR = 5.279, 95%CI: 2.782-38.454, P = 0.003; OR = 4.309, 95%CI: = 2.144-11.793, P < 0.001; and OR = 1.534, 95%CI: 1.062-2.216, P = 0.022, respectively). Thirteen patients died within 6 wk. A model for end-stage liver disease (MELD) score ≥ 18 and an HVPG ≥ 20 mmHg were associated with 6-wk mortality (OR = 2.162, 95%CI: 1.145-4.084, P = 0.017 and OR = 1.423, 95%CI: 1.222-1.657, P < 0.001, respectively). MELD score and HVPG in combination allow for early identification of patients with AVH who are at substantially increased risk of death over the short term.

    ABSTRACT: To evaluate the role of multi-detector row computed tomography (MDCT) angiography for assessing the therapeutic effects of percutaneous transhepatic variceal embolization (PTVE) for esophageal varices (EVs). The subjects of this prospective study were 156 patients who underwent PTVE with cyanoacrylate for EVs. Patients were divided into three groups according to the filling range of cyanoacrylate in EVs and their feeding vessels: (1) group A, complete obliteration, with at least 3 cm of the lower EVs and peri-/EVs, as well as the adventitial plexus of the gastric cardia and fundus filled with cyanoacrylate; (2) group B, partial obliteration of varices surrounding the gastric cardia and fundus, with their feeding vessels being obliterated with cyanoacrylate, but without reaching lower EVs; and (3) group C, trunk obliteration, with the main branch of the left gastric vein being filled with cyanoacrylate, but without reaching varices surrounding the gastric cardia or fundus. We performed chart reviews and a prospective follow-up using MDCT images, angiography, and gastrointestinal endoscopy. The median follow-up period was 34 mo. The rate of eradication of varices for all patients was 56.4% (88/156) and the rate of relapse was 31.3% (41/131). The rates of variceal eradication at 1, 3, and 5 years after PTVE were 90.2%, 84.1% and 81.7%, respectively, for the complete group; 61.2%, 49% and 42.9%, respectively, for the partial group; with no varices disappearing in the trunk group. The relapse-free rates at 1, 3 and 5 years after PTVE were 91.5%, 86.6% and 81.7%, respectively, for the complete group; 71.1%, 55.6% and 51.1%, respectively, for the partial group; and all EVs recurred in the trunk group. Kaplan-Meier analysis showed P values of 0.000 and 0.000, and odds ratios of 3.824 and 3.603 for the rates of variceal eradication and relapse free rates, respectively. Cyanoacrylate in EVs disappeared with time, but those in the EVs and other feeding vessels remained permanently in the vessels without a decrease with time, which is important for the continued obliteration of the feeding vessels and prevention of EV relapse. MDCT provides excellent visualization of cyanoacrylate obliteration in EV and their feeding veins after PTVE. It confirms that PTVE is effective for treating EVs.

    ABSTRACT: To compare the efficacy of modified percutaneous transhepatic variceal embolization (PTVE) with 2-octyl-cyanoacrylate (2-OCA) and endoscopic variceal obturation (EVO) with an injection of 2-OCA for prophylaxis of gastric variceal rebleeding. In this retrospective study, the medical records of liver cirrhosis patients with gastric variceal bleeding who underwent either endoscopic 2-OCA (EVO) or modified PTVE using 2-OCA at Shandong Provincial Hospital from January 2006 to December 2008 were reviewed. Patient demographics, rebleeding rate, survival rate, and complications were compared between the two groups (PTVE and EVO). All results were expressed as mean ± SD, or as a percentage. Quantitative variables were compared by two sample Student t tests, and qualitative variables were compared by the Fisher exact test or the χ(2) test (with Yates correction) where appropriate. A P value less than 0.05 was considered significant. Statistical computation was performed using SPSS 13.0 software. A total of 77 patients were included; 45 patients who underwent EVO and 32 patients who received PTVE. During the follow-up (19.78 ± 7.70 mo in the EVO group, vs 21.53 ± 8.56 mo in the PTVE group) rebleeding occurred in 17 patients in the EVO group and in 4 patients in the PTVE group (37.78% vs 12.5%, P = 0.028). The cumulative rebleeding-free rate was 75%, 59%, and 49% in 1, 2, and 3 years respectively for EVO, and 93%, 84%, and 84% for PTVE (P = 0.011). Cox analysis was used to identify independent factors that predicted rebleeding after treatment. Variables including age, gender, cause, Child-Pugh classification, size of gastric varices (GV), location of GV, and treatment methods were analyzed. It was revealed that Child-Pugh classification [risk ratio (RR) 2.10, 95%CI: 1.03-4.28, P = 0.040], choice of treatment (RR 0.25, 95%CI: 0.08-0.80, P = 0.019), and size of GV (RR 2.14, 95%CI: 1.07-4.28, P = 0.032) were the independent factors for predicting rebleeding. Follow-up computed tomography revealed that cyanoacrylate was retained in the varices and in the feeding veins of PTVE patients. During the follow-up, eight patients in the EVO group and four patients in the PTVE group died. The cumulative survival rates at 1, 2, and 3 years were 93%, 84%, and 67% respectively in the EVO group, and 97%, 88%, and 74% respectively in the PTVE group. The survival rates were not significantly different between the two groups (P = 0.432). Cox analysis showed that the Child-Pugh classification was the most significant prognostic factor of survival (RR 2.77, 95%CI: 1.12-6.80, P = 0.027). The incidence of complications was similar in both groups. With extensive and permanent obliteration of gastric varices and its feeding veins, PTVE with 2-OCA is superior to endoscopic 2-OCA injection for preventing gastric variceal rebleeding.

    ABSTRACT: To evaluate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) plus embolotherapy in the treatment of patients with gastroesophageal varices. A total of 36 patients with gastroesophageal varices underwent the therapies of TIPS plus embolotherapy from July 2005 to March 2011 at Provincial Hospital Affiliated to Shandong University. The rechecked items included abdominal ultrasound examination, liver function test and blood routine examination at Day 7 post-operation. All received endoscopic examinations at Month 1. The technical success rate of TIPS plus embolotherapy was 100%. The portal vein pressures declined from (28 ± 8) mm Hg (1 mm Hg = 0.133 kPa) to (14 ± 7) mm Hg at post-operation. Angiography showed gastroesophageal varices disappeared in all patients. Both liver function and gastroesophageal varices markedly improved. During the follow-up period of 3 - 6 months, 4 cases had hepatic encephalopathy and 1 case stent restenosis at post-operation. And most cases were resolved after treatment. No rebleeding occurred during the follow-up period. The combined modality of TIPS plus embolotherapy can effectively lower portal vein pressure and cure esophageal and gastric varice bleeding. As a safe and excellent interventional procedure with fewer complications and a lower recurrence rate of portal hypertension, it has great clinical values in the treatment of portal hypertension and gastroesophageal varices.

    ABSTRACT: To test the safety and validity of percutaneous transhepatic variceal embolization (PTVE) with tissue adhesive cyanoacrylate. PTVE with cyanoacrylate was performed on 92 patients with gastroesophageal varices, 53 males and 39 females, aged 62.5 (7-84): cyanoacrylate was injected into the varices and the afferent veins. Endoscopy and CT were performed to evaluate the embolization. PTVE was successfully completed in 89 of the 92 patients with a technical success rate of 96.7%, and 3 patients died within 1 month. Among the other 86 patients 3 types of cyanoacrylate embolization were achieved: embolization of coronary vein, vessels around gastric fundus, and variceal lower esophagus veins in 40 patients, embolization of coronary vein, gastric fundus and pericardial varices in 33 patients, and embolization of sole gastric coronary vein stem in 13 patients. Acute variceal bleeding in 18 patients was immediately arrested after the procedure, with an acute bleeding control rate of 100%. Eighty-six patients were followed up for 31.5 (6-52) months. The general variceal recurrence rate was 14.1% (10/71), and the variceal recurrence rate of the coronary vein embolization group was 100% (2/2), significantly higher than those of the groups of esophagus and fundus embolization and gastric fundus and cardia varices embolization [7.5% (3/40) and 17.2% (5/29) respectively, P = 0.006]. The general rebleeding rate was 16.3% (14/86), and the rebleeding rates of the group of coronary vein embolization was 69.2% (9/13), significantly higher than those of the groups of esophagus and fundus embolization and gastric fundus and cardia varices embolization [7.5% (3/40) and 15. 2% (5/33) respectively, P = 0.0092]. No obvious ectopic embolization was found. The mortality was 24.7% (22/89). The cause of rebleeding in coronary vein embolization was mainly recurrent variceal bleeding, whereas that in the group of fundus and esophagus variceal embolization was mainly hypertensive gastropathy. PTVE with cyanoacrylate is safe and effective for the obliteration of gastroesophageal varices in cirrhotic patients.

    ABSTRACT: To study the clinical efficacy of TH glue (cyanoacrylate) obliteration of esophageal varices and partial spleen embolization (PSE) in the treatment of esophageal varices bleeding. TH glue was injected into the gastroesophageal varices and their feeder veins in 84 patients. According to the size of the varices and their blood flow, the TH glue was injected alone or after a steel coil was placed at the ostium of the feeder vein. Sometimes absolute alcohol was also injected into the varices. PSE was performed after the TH glue obliteration in all patients. (1) The TH glue obliteration was performed on 81 patients with a success rate of 96.4%. Three patients died from the procedure. (2) The left gastric vein coronary, gastric varices, pericardial varices, and lower esophageal veins were obliterated in 38 patients (group 1). Left gastric vein, gastric varices, and pericardial veins were obliterated in 31 patients (group 2). Only the main gastric coronary vein was obliterated in 9 patients (group 3). The disappearance rate of the esophageal varices was 71.1% (27/38), 35.5% (11/31) and 0% (0/9) in the three groups. (3) During a follow-up of 6-49 months, rebleeding occurred in 13 of all 78 (16.7%) patients, and it was 7.9% (3/38), 12.9% (4/31) and 66.7% (6/9) respectively in the three groups. Our results suggest percutaneous transhepatic TH glue obliteration of esophageal varices and PSE are safe and effective in treating gastroesophageal varicose bleeding.

    ABSTRACT: To evaluate the effect of Ginkgo biloba extract (EGb) on hepatic microcirculation and portal hypertension in CCl4 treated rats. Twenty-five male Wistar rats were divided into a blank, a CCl4 treated and a CCl4 plus EGb treated group, and all were treated for 10 weeks. The free portal vein pressures were measured through catheterizations. Hepatic sinusoidal endothelial cells and other parameters of hepatic microcirculation were studied with transmission electron microscopy. The amounts of malondialdehyde (MDA), endothelin (ET-1), platelet-activating factor (PAF), nitric oxide (NO), cNOS and iNOS in the liver tissues were determined. The portal vein pressure of the CCl4 plus EGb treated group was (7.4 +/- 0.6) mm Hg while the pressure of the CCl4 treated group was (8.7 +/- 0.8) mm Hg. Aggregation of blood cells or microthrombosis in hepatic sinusoids, deposition of collagen in hepatic sinusoids and spaces of Disse, injury of endothelial cells and capillarization of hepatic sinusoid were significantly milder in the EGb group. The amounts of MDA, ET-1, PAF, NO and iNOS were markedly lower in the CCl4 plus EGb treated group than in the CCl4 treated group. The results demonstrated that EGb can decrease the portal vein pressure and improve hepatic microcirculation in CCl4 treated rats. The mechanisms of this effect may involve its inhibition on ET-1, PAF, lipid peroxidation, and down regulation of the hepatic iNOS and NO expressions.
