ABSTRACT

ObjectiveTo investigate the influencing factors for rebleeding and 5-year survival rate after treatment in patients with liver cirrhosis and spontaneous splenorenal shunt (SSRS), and to provide a basis for clinical prognostic assessment. MethodsA total of 95 patients with liver cirrhosis and SSRS who were admitted to Zhongshan Hospital and Xiamen Branch of Fudan University from June 2014 to June 2018 were enrolled, and all patients were followed up for at least 5 years. According to the presence or absence of gastrointestinal bleeding during follow-up, the patients were divided into rebleeding group with 27 patients and non-rebleeding group with 68 patients. The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. Univariate and multivariate Cox regression analyses were used to investigate the influencing factors for the prognosis of patients with SSRS, and the Kaplan-Meier method was used to describe survival outcomes. A Pearson or Spearman correlation analysis was performed. ResultsCompared with the non-rebleeding group, the rebleeding group had significantly higher splenorenal shunt diameter [4.60(3.20 ‍—‍ 5.90) mm vs 3.45(2.10 ‍—‍ 5.45) mm, Z=1.973, P=0.048] and hepatic venous pressure gradient(18.57±6.60 mmHg vs 15.06±5.82 mmHg, t=2.280, P=0.026) and a significantly lower portal vein diameter(14.04±2.90 mm vs 15.45±2.90 mm, t=2.138, P=0.035). The correlation analysis showed that splenorenal shunt diameter was negatively correlated with portal vein diameter(rs=-0.211, P=0.040). Adverse events within 5 years after treatment included rebleeding(27.4%), portal vein thrombosis(11.6%), infection(4.2%), cerebral hemorrhage(1.1%), and cerebral infarction(1.1%). Splenorenal shunt diameter(risk ratio [RR]=1.173, 95% confidence interval [CI]: 1.001‍ ‍—‍ ‍1.374, P=0.048) and superior mesenteric vein diameter(RR=0.844, 95%CI: 0.746 ‍—‍ 0.956, P=0.007) were independent influencing factors for gastrointestinal rebleeding within 5 years after treatment. Bilirubin(RR=1.028, 95%CI: 1.010 ‍—‍ 1.046, P=0.002) and blood urea nitrogen(RR=1.347, 95%CI: 1.116 ‍—‍ 1.625, P=0.002) were independent risk factors for 5-year survival rate after treatment. ConclusionSplenorenal shunt diameter is closely associated with the prognosis of cirrhotic patients, and it is recommended to enhance imaging follow-up of splenorenal shunt diameter for cirrhotic patients with SSRS.

ABSTRACT

According to the pathophysiological characteristics, upper gastrointestinal bleeding can be divided into acid related disease bleeding and esophageal and gastric varices bleeding. Esophageal and gastric variceal bleeding is a common critical condition of Portal hypertension, with dangerous onset and high mortality. With the improvement of endoscopic treatment technology, endoscopy has become the first line treatment plan for esophageal and gastric variceal bleeding. The commonly used endoscopic management methods for varicose veins include variceal ligation, tissue glue combined with sclerosing agent embolization, ultrasound guided coil combined with tissue glue embolization, and other management measures. Early identification of gastrointestinal bleeding related to varicose veins, stratified diagnosis and treatment of high-risk patients, reasonable selection of endoscopic examination timing, and personalized decision-making of treatment choices are key to improving efficacy.

ABSTRACT

Objective:To evaluate the long-term risk of rebleeding in patients with acute esophageal and gastric variceal bleeding and portal vein thrombosis after endoscopic treatment in liver cirrhosis.Methods:From January to December 2022, 57 patients with acute esophageal and gastric variceal bleeding who were treated by endoscopy in the emergency department of the Zhongshan Hospital affiliated to the Fudan University were included in the study. According to the results of portal vein CT angiography (CTA), the patients were divided into thrombosis group and non thrombosis group. We compared the basic information and endoscopic treatment status of two groups of patients. All patients were followed up until 1 year after endoscopic treatment or April 15, 2023, and re bleeding and survival were recorded during the follow-up period. The influencing factors of rebleeding after 1 year of treatment were analyzed.Results:The patient′s age was (55.9±11.4)years old, mainly male [78.95%(45/57)]. The average time from initial bleeding to endoscopic treatment for all patients was (6.6±2.8)days. There was no statistically significant difference between the two groups in terms of age, sex, combined liver malignancy, Child-pugh score, first bleeding form, ascites, and first laboratory examination results (including hemoglobin, platelet, Prothrombin time, creatinine) (all P>0.05). There was no statistically significant difference in the history of endoscopic treatment, bleeding distance from endoscopic treatment, the proportion of patients with esophageal varices and gastric varices, the proportion of patients with esophageal varices treated with ligation, and the proportion of patients with gastric varices treated with tissue glue between the two groups (all P>0.05). A total of 2 patients died after surgery, and 12 patients experienced rebleeding, including 10 in the thrombotic group and 2 in the non thrombotic group. Kaplan Meier analysis showed that the 1-year rebleeding rate in the thrombotic group was significantly higher than that in the non thrombotic group (59.02% vs 24.71%, RR=6.002, 95% CI: 1.06-34.00, P=0.020 8). Cox multivariate regression analysis suggests that the presence of portal vein thrombosis ( HR=7.669, 95% CI: 1.453-40.472, P=0.016) was an independent risk factor for recurrent bleeding after endoscopic treatment of acute esophageal and gastric variceal bleeding for one year. Conclusions:Portal vein thrombosis in liver cirrhosis increases the risk of recurrent bleeding after endoscopic treatment for acute esophageal and gastric variceal bleeding for one year. For patients with acute Upper gastrointestinal bleeding complicated with portal vein thrombosis, regular endoscopic and ultrasonic follow-up, individualized endoscopic sequential and selective anticoagulation therapy should be carried out.

ABSTRACT

Objective:This study aimed to evaluate the rebleeding risk and prognosis of patients being treated after acute esophageal varices bleeding by two different treatment strategies: sclerosing agent combined with tissue glue injection, esophageal varices ligation (EVL), through comparing the therapeutic effects and securities.Methods:A total of 76 patients who underwent endoscopy and received treatment in Zhongshan Hospital Affiliated to Fudan University due to acute esophageal variceal bleeding were included retrospectively. 6 patients with active bleeding and 70 patients with thrombus in esophagus varices under gastroscopy. Among them, 21 cases were treated with sclerosing agent combined with tissue glue injection (sclerosing tissue glue group), and 55 cases were treated with EVL (EVL group). The emergency endoscopic diagnosis and treatment of the two groups were compared, and the risk factors of rebleeding 6 months after endoscopic treatment were analyzed by univariate and multivariate analysis.Results:All patients received endoscopic treatment successfully. During the follow-up period of 6 months after endoscopic treatment, rebleeding occurred in 13 cases. Kaplan Meier analysis showed that the 6-month rebleeding rate in the sclerosing tissue glue group was significantly higher than that in the EVL group (41.6% vs 12.3%, P=0.011). There were 8 deaths in total. Kaplan Meier analysis showed that there was no significant difference in 6-month mortality between the two groups (17.5% vs 10.1%, P=0.616). Multivariate analysis further showed that malignant tumor ( HR=3.700, 95% CI: 1.187-11.536, P=0.024) and treatment mode of esophageal variceal bleeding ( HR=4.834, 95% CI: 1.443-16.193, P=0.011) were independent risk factors for rebleeding 6 months after endoscopic treatment of acute esophageal variceal bleeding. Conclusions:This study found that EVL and the combining injection of lauromacrogol and cyanoacrylate could be used in emergent hemostatic treatment for acute esophageal varices bleeding. Moreover, EVL is the prioritized approach in endoscopic emergency treatment with a lower rebleeding rate and fewer complications. Sclerotherapy combined with tissue glue can be used as one of the measures of emergency treatment, which is not better than ligation.

ABSTRACT

Objective:In this study, the liver, spleen, and hepatic portal vein in the portal venous phase images of abdominal enhanced computed tomography (CT) are artificially segmented and annotated, and the radiomics features are extracted from them. A model for predicting portal pressure in patients with hepatitis B virus (HBV) related cirrhosis is constructed by combining radiomics features with clinical indicators.Methods:A total of 171 patients who had abdominal enhancement CT examination and trans-jugular hepatic venous pressure gradient (HVPG) measurement at the same time were enrolled from January 2016 to May 2020 in the Zhongshan Hospital Affiliated to Fudan University. The liver, spleen, and hepatic portal vein in the portal venous phase images of the CT were manually labeled by using ITK-SNAP 3.8 software. The radiomics features of these three sites were extracted using Python programming, and an HVPG prediction model was established.Results:A total of 171 patients was included in the study. The average age was (51.1±10.3)years, of which 134(78.4%) were males, and the average HVPG was 16.87±5.695. A total of 2 553 radiomics features were extracted from three sites of the portal venous phase images of abdominal enhanced CT in each patient. The 2 553 features extracted were screened using LASSO, and by combing with clinical features and radiomics features, the predictive model of HVPG was obtained: m_HVPG=31.622+ 0.028 8T×total bile acids-6.31(portal venous wavelet-LHH_glcm_ClusterShade)=0.253(portal venous wavelet-LHL_glszm_LargeAreaLowGrayLevelEmphasis)-20.9(spleen wavelet-LLH_glcm_Correlation)-0.000 127(liver original_shape_SurfaceArea)+ 2.79(liver wavelet-LLH_glcm_ClusterShade). The coefficient of determination R2 was 0.345. Conclusions:The study suggests that radiomics features of the liver, spleen, and portal venous combined with clinical features may be used as a non-invasive method to assess the portal pressure in patients with HBV-related cirrhosis.

ABSTRACT

Objective:To investigate the effect of hepatic venous pressure gradient (HVPG) on the prevention of rebleeding in cirrhotic patients of hepatitis B with gastroesophageal variceal hemorrhage receiving endoscopic therapy, and its influence on prognosis.Methods:Fifty eight patients with esophageal and gastric varices due to cirrhosis of hepatitis B admitted to Minhang Hospital Affiliated to Fudan University (from January 2019 to September 2021, n=18) and Zhongshan Hospital Affiliated to Fudan University (from January to September 2017, n=40) were retrospectively included. All of them underwent HVPG determination and endoscopic treatment. They were divided into HVPG≤18 mmHg group and HVPG>18 mmHg group. The rebleeding and survival status of these patients with endoscopic treatment was compared after a follow-up period of 2 years, and Cox regression was performed to analyze the related factors for rebleeding and survival. Results:A total of 58 individuals were included, which were divided into two groups: HVPG≤18 mmHg group (35) and HVPG>18 mmHg group (23). During the 2-year follow-up after the first endoscopic treatment, 13 patients (22.41%) developed rebleeding, including 4 patients in the HVPG≤18 mmHg group and 9 patients in the HVPG>18 mmHg group. The non-bleeding rate in HVPG≤18 mmHg group was significantly higher than that in HVPG>18 mmHg group (91.3% vs 68.7%, RR=3.54, 95% CI: 1.08-11.60, P=0.026), and the difference was statistically significant. Four patients died, including 1 patient in the HVPG≤18 mmHg group and 3 patients in the HVPG>18 mmHg group. There was no statistically significant difference in 2-year survival between the two groups (96.7% vs 86.5%, RR=4.44, 95% CI: 0.45-43.58, P=0.162). Cox regression multivariate analysis was used to analyze the above data, and the results suggested portal vein thrombosis ( HR=3.826, 95% CI: 1.263-11.585, P=0.018), HVPG>18 mmHg ( HR=4.243, 95% CI: 1.290-13.955, P=0.017) were independent risk factors for rebleeding in 2 years after endoscopic therapy. Conclusions:For patients with high HVPG, it should be fully evaluated and considered to receive other pressure lowering therapy, and treatment conversion should be carried out as soon as possible after endoscopic treatment failure.

ABSTRACT

Objective:To investigate the safety and efficacy of endoscopic ultrasound-guided coil embolization for gastric varices.Methods:Patients with portal hypertension who received endoscopic ultrasound-guided coil embolization for the prophylaxis of gastric variceal bleeding between November 2016 and August 2020 at Zhongshan Hospital, Fudan University were included in the study. The primary evaluation index was the post-operative loss of blood flow in gastric varices, and the secondary indices included the safety of coil embolization, rebleeding rate, portal vein thrombosis changes and patient survival.Results:A total of 13 patients with isolated gastric varices and portal systemic shunt were enrolled, including 6 males and 7 females with the median age of 58 years. The median maximum diameter of the target vessel was 40 mm and the median number of coils used was 2.7. All puncture sites were in the lower part of the esophagus near the cardia, and no active bleeding occurred after deployment of coils. Flow in the gastric varices were confirmed absent by Doppler imaging. In a median follow-up period of 403 days, 2 patients had rebleeding, with the one-year rebleeding rate of 9.1%.Two patients developed portal venous thrombosis after the operation. Two patients died, and the one-year survival rate was 90.0%.Conclusion:Endoscopic ultrasound-guided coil embolization might be an effective option for the treatment of isolated gastric varices with portal systemic shunts.

ABSTRACT

Endoscopic treatment is the main therapy for controlling variceal bleeding and secondary prophylaxis of rebleeding of gastroesophageal varices of portal hypertension. Endoscopic treatment of gastroesophageal varices are developing towards individualization, precision and whole management in recent years. We can diagnose the etiology and characteristic of portal hypertension through medical history, physical examination, laboratory and radiological tests. It is important to identify the etiology of portal hypertension that can control the progress of varices. There is a complex classification of varices. Individualized stratification and treatment selection are based on the results of endoscopic finding, contrast computed tomography (CT), hepatic venous pressure gradient, etc. Modified precise endoscopic injection of cyanoacrylate is important part to improve the efficacy and reduce the complications of endoscopic treatment. We need to pay attention to the complications and comorbidities of portal hypertension, comprehensive management with the multidisciplinary teams, that is the most important thing to improve the efficacy of endoscopic treatment and the prognosis of patients with portal hypertension.

ABSTRACT

Objective:In this study, a simple and easy diagnostic index of sarcopenia based on computed tomography (CT) images, linear skeletal muscle index (LSMI), was proposed and its diagnostic efficiency was verified.Methods:From April 2013 to September 2017, patients with cirrhotic gastroesophageal varices were selected from the Department of Gastroenterology, Zhongshan Hospital, Fudan University. The SMI of the third lumbar lower than 50 cm 2/m 2 in male and 39 cm 2/m 2 in female was defined as sarcopenia. The sensitivity, specificity, positive predictive value, negative predictive value, Youden index and receiver operating characteristic (ROC) curve were used to evaluate the diagnostic efficacy of LSMI in patients with cirrhotic gastroesophageal varices. Results:A total of 115 patients with cirrhotic gastroesophageal varices were finally recruited. All participants were randomly divided into modeling group ( n=58) and validation group ( n=57). In the modeling group, the area under the ROC curve of LSMI was 0.913(95% CI:0.84-0.986, P<0.001) in total population, 0.895(95% CI:0.793-0.997, P<0.001) in male and 0.917(95% CI:0.782-1.000, P<0.008) in female. The cut-off value of LSMI was 24.114 cm 2/m 2 in male and 22.54 cm 2/m 2 in female. According to the diagnostic cut-off value of the modeling group, the area under the ROC curve of LSMI was 0.846(95% CI:0.737-0.954, P<0.001) in the validation group. The sensitivity, specificity, positive predictive value, negative predictive value and Youden index were 88.5%, 80.6%, 79.3%, 89.3% and 0.691, respectively. Conclusions:48.7% of patients with cirrhosis of esophageal and gastric varices have sarcopenia. LSMI is a simple and convenient method for diagnosis of sarcopenia in patients with liver cirrhosis.

ABSTRACT

Objective:The aim of this study was to investigate the prognostic value of vitamin B12 as the non-invasive biomarker to predict long-term rebleeding rate in cirrhotic patients with esophagogastric varices.Methods:From Dec 1, 2016 to Dec 31, 2017, cirrhotic patients with esophagogastric varices who had been admitted to Zhongshan Hospital affiliated to Fudan University were enrolled. All these patients received endoscopic treatment to prevent variceal rebleeding. The serum vitamin B12 and folic acid levels were measured in all of them. The receiver operating characteristic (ROC) analysis, Kaplan-Meier analysis, univariate and multivariate cox regression analysis were conducted to explore the value of vitamin B12 in predicting 3-year variceal rebleeding in cirrhotic patients with esophagogastric varices after endoscopic treatment.Results:115 patients were included. The ROC curve analysis indicated that the optimal cutoff value of vitamin B12 for 3-year variceal rebleeding was 567.25 pg/ml. According to the cut-off value, the patients were divided into high-level vitamin B12 group ( n=49) and low-level vitamin B12 group ( n=66). Compared with the low vitamin B12 group, the high vitamin B12 group had lower albumin level, less male (63.3% vs 80.3%), and higher 3-year rebleeding rate ( P<0.05). Cox analysis showed that vitamin B12 and platelet were independent prognostic factors for 3-year rebleeding in patients with variceal bleeding. Conclusions:Elevated peripheral blood vitamin B12 predicts a higher risk of long-term rebleeding in patients with liver cirrhosis and esophagogastric varices.

ABSTRACT

Objective:To discuss the effects of transjugular intrahepatic portosystemic shunt (TIPS) procedure on hemodynamics in cirrhotic patients.Methods:A total of 23 cirrhotic patients for TIPS insertion were enrolled from January 2018 to October 2018. Serum N-terminal pro-B-type natriuretic peptide (NT-proBNP), transthoracic echocardiography and non-invasive cardiac output measurement based on impedance cardiogram were carried out before and 24h, 1 month, 6 months after TIPS in order to observe cardiac function and hemodynamic changes after TIPS.Results:Significant increases in right atrial area [(17.2±4.0) cm 2 vs. (15.0±3.4) cm 2, P<0.05], right ventricular area [(15.1±3.8) cm 2 vs. (13.7±3.5) cm 2, P<0.05] and left ventricular volume [(97.4±21.5) ml vs. (91.1±22.7) ml, P<0.05] were observed 24 h after TIPS. These changes were accompanied with significant reduction in collapsible index of inferior vena cava [(20.7± 8.1)% vs. (28.6±11.3)%, P<0.01] and elevation in pulmonary arterial systolic pressure [(36.0±8.4) mmHg (1 mmHg=0.133 kPa) vs. (31.8±5.4) mmHg, P<0.01]. There also existed significantly elevated serum NT-proBNP [(551.2±325.1) ng/L vs. (124.2±94.4) ng/L, P<0.01], cardiac output [(5.82±0.96) L/min vs. (5.12±1.28) L/min, P<0.01], cardiac index [(3.47±0.64) L·min -1·m -2 vs. (3.05±0.78) L·min -1·m -2, P<0.01], early diastolic filling rate [(59.0±14.3)% vs. (54.5±11.0)%, P<0.05], and reduced systemic vascular resistance index (SVRi) [(1 798.4±357.3) dyne·s·cm -5·m -2 vs. (2 195.7±508.7) dyne·s·cm -5·m -2, P<0.01] 24 h after TIPS. At the end of 6-month follow-up, all these parameters, but not SVRi, returned towards baseline values. Moreover, peak early to late diastolic tissue velocity ratio at the level of lateral mitral annulus (E′/A′) was significantly higher at the end of 6-month follow-up than that at baseline (1.06±0.32 vs. 0.90±0.45, P<0.05). Neither the right ventricular fractional area changes nor the left ventricular ejection fractions during the follow-up period were different from those at baseline ( P>0.05). Conclusion:Cirrhotic patients who had no cardiovascular pathologies had adequate adaptation and good compensation ability to reach a new hemodynamic homeostasis for the increased volume load after TIPS insertion.

ABSTRACT

Objective:To predict the efficacy of endoscopic tissue adhesives in the treatment of gastric varices in patients with liver cirrhosis by Nomogram model.Methods:From August 2014 to September 2017, 158 patients with liver cirrhosis caused esophagogastric variceal bleeding and received endoscopic tissue adhesives treatment at Zhongshan Hospital, Fudan University were collected. All patients were followed for 12 months. The primary outcome was rebleeding. The factors of rebleeding after endoscopic treatment of esophagogastric varices were analyzed. Nomogram prognostic model was developed and compared with Child-Pugh grading, computed tomography angiography (CTA) and hepatic venous pressure gradient (HVPG) in prognostic accuracy in rebleeding after endoscopic treatment in liver cirrhosis caused esophagogastric varices. Univariate and multivaricate Cox regression analysis, Kaplan-Meier curve and log-rank test were performed for statistical analysis.Results:During the follow-up, rebleading occurred in 18 cases (11.4%), 37 cases (23.4%) and 49 cases (31.0%) at 2, 6, and 12 months after endoscopic treatment. The results of univariate Cox regression analysis showed the risk factors of rebleeding after endoscopic treatment of gastric varices included gender, alcoholic liver cirrhosis, diabetes mellitus, Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence vs. absence) HVPG (<16 mmHg vs. ≥16 mmHg, 1 mmHg = 0.133 kPa), extensive portal embolism, esophageal varices, type 2 gastric varices, injection points of tissue adhesive (≤3 points vs. > 3 points), injection volume of tissue adhesive (≤ 3 mL vs. > 3 mL) (hazard ratio ( HR)=0.575, 2.018, 1.562, 3.433, 2.945, 1.859, 2.743, 0.324, 1.840, 1.477, and 1.716; 95% confidence interval ( CI) 0.305 to 1.084, 0.902 to 4.514, 1.753 to 6.724, 1.663 to 5.217, 1.012 to 3.415, 0.852 to 8.830, 0.079 to 1.335, 1.012 to 3.317, 0.839 to 2.602, and 0.935 to 3.152; all P<0.2). The results of multivariate Cox regression analysis indicated that Child-Pugh grade, extraluminal vessels by CTA, and HVPG ( HR = 2.095, 95% CI 1.099 to 3.995, P = 0.025) were all independent risk factors of rebleeding after endoscopic treatment of gastric varices ( HR=2.665, 2.886, and 2.095; 95% CI 1.339 to 5.300, 1.580 to 5.271, and 1.099 to 3.995; all P<0.05). Kaplan-Meier curves showed that Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence or absent) and HVPG (<16 mmHg vs. ≥16 mmHg) could effectively predict cumulative non-rebleeding rate in one year after endoscopic treatment of gastric varices, and the differences were statistically significant (all P<0.05). Receiver operataring characteristic curve analysis demonstrated that the predictive value of the model combined with Child-Pugh grade, extraluminal vessels on CTA and HVPG was higher than that of Child-Pugh grade and HVPG (AUC=0.746, 0.673 and 0.585; 95% CI 0.662 to 0.829, 0.583 to 0.762, and 0.486 to 0.683; P<0.01, P=0.001 and P=0.089, respectively). Patients were divided into low, medium, and high-risk groups according to the 25th and 75th percentiles of the Nomogram score. The results showed that Nomogram model could effectively distinguish high-risk groups of rebleeding after endoscopic treatment of gastric varices, and the difference was statistically significant ( P <0.01). Conclusions:Extraluminal vessels on CTA, HVPG and Child-Pugh grade are independent prognostic evaluation indexes of rebleeding after endoscopic treatment of gastric varices. The predictive accuracy of Nomogram model based on these three prognostic factors may be better than Child-Pugh grade and HVPG.

The results of univariate Cox regression analysis showed the risk factors of rebleeding after endoscopic treatment of gastric varices included gender, alcoholic liver cirrhosis, diabetes mellitus, Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence vs. absence) HVPG (<16 mmHg vs. ≥16 mmHg, 1 mmHg = 0.133 kPa), extensive portal embolism, esophageal varices, type 2 gastric varices, injection points of tissue adhesive (≤3 points vs. > 3 points), injection volume of tissue adhesive (≤ 3 mL vs. > 3 mL) (hazard ratio (HR)=0.575, 2.018, 1.562, 3.433, 2.945, 1.859, 2.743, 0.324, 1.840, 1.477, and 1.716; 95% confidence interval (CI) 0.305 to 1.084, 0.902 to 4.514, 1.753 to 6.724, 1.663 to 5.217, 1.012 to 3.415, 0.852 to 8.830, 0.079 to 1.335, 1.012 to 3.317, 0.839 to 2.602, and 0.935 to 3.152; all P<0.2). The results of multivariate Cox regression analysis indicated that Child-Pugh grade, extraluminal vessels by CTA, and HVPG (HR = 2.095, 95% CI 1.099 to 3.995, P = 0.025) were all independent risk factors of rebleeding after endoscopic treatment of gastric varices (HR=2.665, 2.886, and 2.095; 95% CI 1.339 to 5.300, 1.580 to 5.271, and 1.099 to 3.995; all P<0.05). Kaplan-Meier curves showed that Child-Pugh grade (Grade A vs. B or C), extraluminal vessels on CTA (presence or absent) and HVPG (<16 mmHg vs. ≥16 mmHg) could effectively predict cumulative non-rebleeding rate in one year after endoscopic treatment of gastric varices, and the differences were statistically significant (all P<0.05). Receiver operataring characteristic curve analysis demonstrated that the predictive value of the model combined with Child-Pugh grade, extraluminal vessels on CTA and HVPG was higher than that of Child-Pugh grade and HVPG (AUC=0.746, 0.673 and 0.585; 95% CI 0.662 to 0.829, 0.583 to 0.762, and 0.486 to 0.683; P<0.01, P=0.001 and P=0.089, respectively). Patients were divided into low, medium, and high-risk groups according to the 25th and 75th percentiles of the Nomogram score. The results showed that Nomogram model could effectively distinguish high-risk groups of rebleeding after endoscopic treatment of gastric varices, and the difference was statistically significant (P <0.01).@*Conclusions@#Extraluminal vessels on CTA, HVPG and Child-Pugh grade are independent prognostic evaluation indexes of rebleeding after endoscopic treatment of gastric varices. The predictive accuracy of Nomogram model based on these three prognostic factors may be better than Child-Pugh grade and HVPG.

ABSTRACT

Objective@#To study the role of virtual gastroscopy simulator in the examination of clinical practice skills of gastrointestinal specialists.@*Methods@#A multi-center empirical study was carried out. In June 2018, ninety participants from three tertiary care teaching hospitals in China, including Zhongshan Hospital of Fudan University, Shanghai Tongji Hospital and Xiangya Hospital of Central South University, took part in the examination. Participants were selected as follows: 30 specialists without any experience of gastroscopy exams, 30 with basic knowledge (gastroscopy exams <500 cases) and 30 with good skill (gastroscopy exams ≥500 cases). These 90 students participated in this empirical study after theoretical study and simulator training. Among them, 50 (55.6%) were undergraduates, 25 (27.8%) masters, and 15 (16.7%) doctors; 42 (46.7%) were residents, 39 (43.3%) attending physicians, and 9 (10.0%) deputy chief physicians. The assessment was divided into two parts. The first part was to use the simulator (GI mentor II) for ballooning within 10 minutes, with a total score of 40 points. The second part was a complete gastroscopy exam on the simulator, including preparation before gastroscopy exam, gastroscopy exam, post - exam management and related knowledge quiz. The difficulty and discrimination of the assessment plan were evaluated by the extreme grouping method parameters (difficulty P definition: <0.3 was difficult, 0.3 to 0.7 was medium, ≥0.7 was easy; discrimination degree D definition: <0 was poor, 0 to 0.2 was medium, ≥0.2 was good), and by comparing the virtual gastroscopy assessment scores of different experience, academic, and professional title groups. The score analysis of the student group was expressed using the mastering rate (the average score divided by the total score). The data of the normal distribution was represented by (mean±SD) (range), and the data of the nonnormal distribution was represented by M (P25, P75). Kruskal-Wallis non-parametric test was used for comparison between groups.@*Results@#The total score of 90 students was (82.9±10.9) (55.8 to 99.0), and the mastering rate was 82.9%. The overall difficulty of the first and the second parts were 0.78 and 0.76, respectively, and the difficulty level was easy. The overall discrimination of the first and the second parts were 0.70 and 0.67, respectively, and the discrimination was good. The stratified analysis was performed according to the professional title. The median score was 83.2 (75.5, 89.0) in the residents, 82.5 (71.7, 93.6) in the attending physicians, and 93.5 (88.5, 99.0) in the deputy chief physicians, and the difference was statistically significant (H=6.213, P=0.045). According to the stratification analysis of academic qualifications, the median score was 81.7 (73.0, 87.5) in participants with undergraduate degree, 91.0 (79.0, 95.0) in those with master degree and 88.0 (81.7, 93.5) in those with doctor degree, whose difference was statistically significant (H=9.233, P=0.010). The stratified analysis of the second part showed that the median scores of the "operational process" part of the low, medium and high basis group were 33.0 (30.5, 36.5), 34.0 (32.0, 36.0) and 37.0 (35.0, 37.5), respectively, whose difference was statistically significant (H=7.603, P=0.022). The median scores of the "operational process" section of the resident, attending physician, and deputy chief physician were 33.0 (30.5, 35.0) points, 36.0 (34.0, 37.5) points and 37.0 (37.0, 37.5) points, respectively, whose difference was statistically significant (H=18.563, P=0.001).@*Conclusions@#The virtual gastroscopy simulator can reflect the true level of gastroscopy exam skills of the students. The examination questions are moderately difficult, and there is a good discrimination of the exam.

ABSTRACT

Objective@#To evaluate Chinese clinical practice guideline/consensus for digestive diseases published in the past five years in order to recommend the high-quality guidelines and help with the promotion and implementation of them.@*Methods@#From January 2013 to June 2018, the officially published Chinese practice guideline/consensus for digestive diseases were selected. The inclusion and exclusion criteria of the guideline/consensus was evaluated by "Evaluation Criteria for Chinese Clinical Practice Guidelines 2017(AGREE-China 2017)" . The guideline/consensus were independently scored by three evaluators and then calculated the average value. Descriptive analysis methods were used to analyze the Chinese clinical practice guideline/consensus for digestive diseases. Those with the total score more than 40.0 points were included in the recommended list.@*Results@#A total of 119 officially published clinical practice guideline/consensus of digestive diseases were retrieved, and 74 clinical practice guideline/consensus for digestive diseases were included in the evaluation. Among them, 18 (24.3%, 18/74) scored over 60.0 points, 31 (41.9%, 31/74) scored between 40.0 and 59.9 points. Finally 48 guideline or consesus were selected for the recommended list 19 cases of esophagus and gastrointestinal diseases, 18 cases of liver diseases, five cases of biliary and pancreafic diseases, and six cases of digestive endoscopy. The three guideline/consensus with the high scores (> 80.0 points) were The Fifth Chinese National Consensus Report on the Maragement of Helicobacter pylori Infection, Consensus on the Diagnosis and Treatmeat of Cholestatic Liver Disease (2015) and Guidelines for the Prevention and Treatment of Chroaic Hepatitis B (2015 Update). The higher the score of the guideline/consensus, the more scientific and rigorous the method, and the clearer the evaluation of evidence grade and the description of the formation of recommendations. Compared with international standards of guideline/consensus development, there are still some problems in Chinese guidelines or consensus such as no explanation of retrieval strategy, no basis of evidence classification and no description of the formation process from evidence to recommendation.@*Conclusions@#The quality of Chinese clinical practice guideline/consensus for digestive diseases has been improved year by year. However the scientific aspects need to be further improved. AGREE-China which demonstrates good validity, realiability and practicability is easy and clear to use.

ABSTRACT

Objective@#To use the meta-analysis in evaluating the hemorrhage-prevention value of second-look endoscopy after endoscopic submucosal dissection (ESD) for early gastric cancer.@*Methods@#A literature search was conducted to identify all relevant studies comparing second-look endoscopy and non-second-look endoscopy after gastric ESD. The Medline/PubMed, Ovid, Elsevier ScienceDirect, EBSCO, CNKI and VIP databases were searched systematically. Literature inclusion criteria: (1) all the patients were diagnosed as early gastric cancer receiving ESD; (2) end point of the study included postoperative bleeding rate of ESD. Exclusion criteria: (1) papers of repeated research, review, comment, guideline, etc; (2) non-control study. Meta-analysis method was used to calculate a pooled odds ratio (OR) for developing post-ESD bleeding.@*Results@#The meta-analysis showed that post-ESD bleeding was observed in 40 of 1287 patients (3.1%) without second-look endoscopy and in 40 of 968 patients (4.1%) with second- look endoscopy (OR=1.25, 95% CI: 0.79-1.98), with no significant difference between these two groups. Subgroup analysis on research method still indicated no significant difference of post-ESD bleeding between RCT group (OR=1.45,95%CI: 0.79-2.65) and non-RCT group (OR=1.02, 95%CI: 0.50-2.08) (all P>0.05).@*Conclusion@#Based on meta analysis, second-look endoscopy can not reduce the rate of postoperative bleeding of ESD. Therefore, routine second-look endoscopy after gastric ESD may not be necessary to prevent delayed postoperative bleeding of ESD.

ABSTRACT

BACKGROUND/AIMS: Gastroesophageal variceal hemorrhage is a common complication of portal hypertension. Endoscopic therapy is currently recommended for preventing gastroesophageal variceal rebleed. However, the rate of variceal rebleed and its associated mortality remain concerning. This study is aimed at differentiating patient response to endoscopic therapy based on endoscopic ultrasound (EUS) findings. METHODS: One-hundred seventy patients previously treated with repeat endoscopic therapy for secondary prophylaxis were enrolled and classified into two groups based on treatment response. Prior to consolidation therapy, all patients received an EUS examination to observe for extraluminal phenomena. All available follow-up endoscopic examination records were retrieved to validate study results. RESULTS: Of the 170 subjects, 106 were poor responders, while 64 were good responders. The presence of para-gastric, gastric perforating, and esophageal perforating veins was associated with poor patient response (p < 0.001). The odds ratio for para-gastric veins was 5.374. Follow-up endoscopic findings for poor responders with incomplete variceal obliteration was closely correlated with the presence of para-gastric veins (p=0.002). CONCLUSIONS: The presence of para-gastric veins is a characteristic of poor response to endoscopic therapy for treating gastroesophageal varices. Early identification of this subgroup necessitates a change in course of treatment to improve overall patient outcome.
