Abstract
Background Portal hypertension commonly occurs due to liver cirrhosis, and esophageal varices (EV) is one of the major complications associated with it. The most common cause of death in liver cirrhosis is EV bleeding. Hence, GE screening for EV is required, which is an invasive procedure. Regular use of endoscopy results in low compliance due to cost and discomfort for patients. Hence, identifying non-invasive markers that could grade EV provides a useful screening tool for family physicians and primary health centers (PHCs) by referring the patient to higher centers for definitive treatment, which could reduce mortality due to variceal bleeding in cirrhotic patients. Aims To assess non-invasive predictors of grade EV in patients diagnosed with liver cirrhosis. Settings and Design Cross-sectional study. Methods and Material A total of 109 patients with liver cirrhosis underwent clinical and biochemical evaluation, USG abdomen with spleen bipolar diameter, ascitic fluid analysis, and upper GE with a grade of EV are recorded. Statistical Analysis Used SPSS software with Student t-test, Chi-square t-test, analysis of variance, receiver operator characteristic (ROC) curves, and Spearman correlation with 95% CI is used. P <0.05 is considered significant. Results Aminotransferase to Platelet count Ratio Index (APRI) score >1.815, PC/SD ≤909, and SAAG >1.1g/dl showed EV in liver cirrhosis (P < 0.05). The order of prediction with ROC curves shows APRI score > PC/SD > SAAG. In grading EV, APRI scores of 1.9-2.5 and >2.5 showed small and large EV, respectively (P < 0.05). Conclusions APRI score may be used in PHC as an early intervention to grade EV and refer the patient to higher centers for definitive treatment. This would prevent the progression of varices to rupture and reduce mortality due to variceal bleeds in liver cirrhosis patients.

Correlation of non-invasive parameters with upper gastrointestinal endoscopy findings for presence and grading of gastroesophageal varices in liver cirrhosis patients. J Family Med Prim Care 2024; 13:1347-1353.

Abstract
Background Development of esophageal varices is one of the major complications of liver cirrhosis, and endoscopy is used to see the presence, grading, and long-term monitoring of esophageal varices which is an invasive and unpleasant procedure. There is no adequate data available showing noninvasive methods can be used for the same. Methods Seventy patients with liver cirrhosis participated in the study. Factors like portal vein diameter, spleen size, platelet count, serum bilirubin, Child-Pugh score, prothrombin time (PT), and PT INR were observed and correlated endoscopically with the presence and grading of esophageal varices in all patients. Results The platelet count, portal vein diameter, serum bilirubin, spleen bipolar diameter, and PT had statistically significant correlations with the presence of varices. Among them, platelet count, portal vein diameter, and serum bilirubin also had statistically significant correlations with the grading of varices. Monitoring of these noninvasive parameters can help in monitoring variceal growth. Conclusions Noninvasive parameters can be used effectively to predict the presence and grading of esophageal varices and at the same time keep the rate of undiagnosed varices acceptably low. By using noninvasive parameters, patients can be benefited by decreasing the requirement of repeated endoscopic evaluation which is an unpleasant procedure and availability is also limited.

Abstract
BACKGROUND Chronic liver infections and diseases lead to chronic liver injury, which results in fibrosis. Due to this continuous scarring and regeneration, cirrhosis occurs, which is also responsible for several adverse sequelae, including but not limited to esophageal varices. Cirrhosis has resulted in patients' increased morbidity and mortality, especially in low socioeconomic settings such as Pakistan. Endoscopy is the gold standard for measuring the presence or absence of esophageal varices, along with their grade. Currently, some non-invasive markers (aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), fibrosis 4 (FIB-4), AAR to platelet ratio index (AARPRI), aspartate aminotransferase-to-platelet ratio index (APRI), S-index, King's score) are being established that make use of laboratory tests, such as a complete blood profile, liver function profile, and coagulation profile, to estimate the extent of hepatic fibrosis. OBJECTIVES The objective of this study is to establish a correlation between non-invasive markers of fibrosis and the presence of esophageal varices and to assess their potential as a substitute for gastrointestinal endoscopy screening. Additionally, the study aims to compare these six scores, thereby generating data on their individual and relative accuracy. METHODOLOGY This was a cross-sectional study conducted at the Shalamar Institute of Health Sciences, Lahore, Pakistan. Outpatient (OPD) data were obtained from the Shalamar online portal system from June 2022 to December 2022. Laboratory tests, abdominal ultrasounds, and endoscopy results were accessed and recorded in the questionnaire. The patient's medical records and contact numbers were also noted in case further questions arose. Data were then compiled into a Microsoft Excel spreadsheet (Microsoft Corp., Redmond, WA) and analyzed after computing the non-invasive procedure formulas. It was analyzed using IBM SPSS Statistics for Windows, version 20.0 (IBM Corp., Armonk, NY). P-values were calculated, and conclusions were drawn. RESULTS Of the sample size of 100 patients with liver damage and injury, 60% were male and 40% were female. Among males, 15% had a milder (grade 1) degree of esophageal varices, and 45% had a moderate to advanced degree (grades 2-3) of esophageal varices. Among females, 19% had mild (grade 1) varices, while 21% had severe (grade 3) varices. The most common cause of varices in patients who had developed fibrosis and/or cirrhosis was hepatitis C, with a wide margin of other causes. The p-values obtained showed that from the selected list of non-invasive markers of fibrosis, only FIB-4 and AARPRI were statistically significant with p-values of 0.036 and 0.022, respectively. PRACTICAL IMPLICATIONS Though endoscopy is currently the gold-standard procedure for detecting the presence or absence and grade of esophageal varices, it is invasive, which makes the patients extremely uncomfortable and apprehensive. It can also lead to post-procedure infection, internal hemorrhages, and trauma due to instrument use. Due to its invasive nature, some patients also tend to refuse this procedure. Non-invasive fibrosis markers can help make a diagnosis without undergoing an endoscopy, which in turn will improve patient compliance and satisfaction. CONCLUSION It was observed that FIB-4 and AARPRI can be used together as reliable markers to assess the presence or absence of esophageal varices.

Abstract
Background The presence and extent of severity of esophageal varices (EV) in patients with liver cirrhosis (LC) are predicted using noninvasive clinical, biochemical, and imaging parameters. The aim of this study was to investigate the accuracy of noninvasive predictors of EV, such as the platelet count-to-spleen diameter ratio (PSR), platelet count-to-spleen volume ratio (PSVR), spleen size (SZ), and a combination of these markers in determining the severity of EV in patients with cirrhosis. Methods We recruited 82 inpatients with LC from the Department of Gastroenterology at the First Affiliated Hospital of Guangxi Medical University between January 2018 and December 2019 for this diagnostic investigation. All patients underwent endoscopy, ultrasound, computed tomography, and routine laboratory investigations. For the study, we evaluated and compared the diagnostic accuracy of PSR, PSVR, SZ, and their combinations. Results There were significant differences in the area under the receiver operating characteristic (ROC) curve (AUC) in the prediction of severe and moderate/severe EV for all the variables. PSR+PSVR had the highest AUC at 0.735 (95% CI: 0.626-0.826) and 0.765 (95% CI: 0.659-0.852) for predicting severe and moderate/severe EV, respectively. There were statistically significant differences in the AUCs (95% CI) for PSR, PSVR, and PSR+PSVR in predicting the existence of EV. As per the overall model quality chart, the combination of PSR+PSVR was the best indicator for detecting the presence of EV (AUC, 0.696; 95% CI: 0.584-0.792). Conclusion In our study, we found that these noninvasive parameters could predict the extent of severity of EV in patients with LC. We anticipate the use of a combination of PSR + PSVR to emerge as the superior indicator as studies progress.

Abstract
INTRODUCTION Variceal haemorrhage is a life-threatening complication that occurs in up to 40% of patients with chronic liver disease including cirrhosis. It is associated with a mortality rate of 20% with each episode of variceal bleeding. Esophagogastroduodenoscopy is the gold standard for the detection of esophageal varices but is an invasive procedure and not very cost-effective. Our study was designed to correlate the presence of esophageal varices on endoscopy with the liver stiffness measurement using liver elastography in patients with chronic liver disease. We also compared various non-invasive predictors like laboratory parameters and ultrasound features and correlated them with the presence of varices in patients with chronic liver disease. METHODOLOGY This prospective observational study was conducted in a tertiary-care hospital in South India from November 2017 to April 2019. All patients with chronic liver disease were subjected to endoscopy, and the presence of esophageal varices and their grading was noted. The predictive efficacy of ultrasound elastography using Toshiba Aplio 500 ultrasound two-dimensional shear wave elastography (2D-SWE) in predicting esophageal varices was calculated and compared with the efficacy of predicting esophageal varices by other non-invasive parameters like laboratory investigations, abdominal ultrasound, and liver scores like Child-Turcotte-Pugh (CTP) score, model for end-stage liver disease (MELD) score, fibrosis 4 (FIB-4) score, aspartate aminotransferase-to-platelet ratio index (APRI) score, and aspartate aminotransferase/alanine aminotransferase ratio (AAR). RESULTS The study included a total of 168 patients out of which 57% (96 patients) had no varices. About 52 patients (72.2%) had F1/Grade I varices, 9 (12.5%) had F2/Grade II varices, and 11 (15.3%) had F3/Grade III varices. The greatest predictive value for esophageal varices was liver stiffness with a diagnostic accuracy of 81.7%. Ultrasound features like coarse echotexture of the liver (66.7%), splenomegaly (67%), dilated portal vein (78.6%), and presence of moderate ascites (66.7%) had a significant statistical association with the presence of esophageal varices. Laboratory parameters like thrombocytopenia of less than 1.5 lakhs/cu.mm (52.8%), albumin <3 g/dL (60.4%), and reversal of albumin/globulin ratio (52.4%) were significant predictors of esophageal varices. The odds ratio for significant scores in predicting oesophageal varices using binary logistic regression was significant in patients whose liver elastography grade was more than F4, CTP score was B, MELD score was >11, and FIB-4 scores was >3.25 and between 1.46 and 3.25. CONCLUSION Liver elastography is a non-invasive procedure that can be a useful tool in predicting esophageal varices in chronic liver disease. Other non-invasive predictors like ultrasound abdomen and laboratory parameters can also be considered a replacement for repeated invasive endoscopy, thus facilitating early intervention and avoiding unfavourable outcomes in patients with chronic liver disease.

Abstract
Objective. To identify any concomitant complications other than bleeding (COTB) before and after endoscopic treatment of esophagogastric variceal bleeding (EGVB) in liver cirrhosis patients and explore the underlying risk factors. Materials and Methods. Cirrhotic patients complicated with EGVB, who underwent interventional endoscopic treatments in our hospital from November 2017 to August 2020, were enrolled in this study. Clinical data were retrospectively analyzed for COTB at admission and within 2 years of the first endoscopic treatment. Patients were screened for potential risk factors of COTB before and after the treatment. Univariate analysis was performed to identify clinical factors of secondary complications, and statistically significant factors were included in the multivariate Cox and logistic regression analyses. Results. Of the 547 patients with cirrhosis, 361 individuals had COTB in the first endoscopic treatment. In this cohort, the top 3 prevalent incidences were portal vein thrombosis (PVT) or spongiosis, cholelithiasis, and pathogenic infections. The COTB did not occur at admission in 171 liver cirrhosis patients but happened at the follow-up. Higher Child-Pugh scores indicated potential risks of multiple concurrent complications, including bleeding. Risk factors for concomitant PVT or cavernous changes after endoscopic treatment of EGVB, pathogenic infections, and cholelithiasis could prolong the cirrhosis symptoms, while noncholestatic cirrhosis patients might have a lower risk than posthepatitis B cirrhosis patients, in the context of a higher degree of EGV and serum level of D-D and a lower blood calcium level. Conclusions. Clinical treatment and interventions can be tailored to avoid other complications during and after EGVB treatment, which can affect the outcome and prognosis of bleeding symptoms.

Abstract
Abstract
Background
Esophagogastroduodenoscopy (EGD) is currently considered the first-line diagnostic procedure of choice for upper gastrointestinal bleeding (UGIB); however, the etiology of bleeding remains unknown in a subset of patients. This study aimed to evaluate the diagnostic yield of EGD in UGIB in pediatrics and determine the clinical predictors for positive endoscopic diagnosis.
Methods
A cross-sectional study was conducted at the pediatrics endoscopy unit, Ain Shams University, Cairo, Egypt, where 100 children were included. They were referred for EGD due to overt UGIB in the form of hematemesis and/or melena. Full medical history, thorough physical examination, laboratory investigations, and endoscopic and histopathologic findings were documented.
Results
Forty-seven males and 54 females were included. Their ages ranged from 3 months to 15 years, with a median age of 4 years. Sixty-five percent presented with hematemesis only, 7% presented with melena only, and 28% presented with hematemesis and melena. An endoscopic diagnosis could be reached in 62% of cases, with Helicobacter pylori (H. pylori) gastritis (23%) and reflux esophagitis (11%) as the most common endoscopic diagnoses, with the former being the most common in children above 4 years and the latter for younger ones. Other diagnoses included non-specific gastritis (8%) and esophageal varices (4%). Presentation with melena only was a negative predictor to reach a diagnosis by EGD, while splenomegaly and thrombocytopenia were independent predictors of variceal bleeding.
Conclusion
EGD is the investigation of choice in children suffering from hematemesis especially in older age groups. Clinical and laboratory parameters might help in the prediction of the underlying etiology.

Abstract
Abstract
Background
Esophageal varices (EV) is the most common apprehensive complication of portal hypertension in patients with cirrhotic liver. Guidelines recommend Upper gastro-intestinal endoscopic screening for EV in patients with newly diagnosed chronic cirrhosis (Imperiale et al. in Hepatology 45(4):870–878, 2007). Yet, it is invasive, time consuming and costly. To avoid unnecessary endoscopy, some studies have suggested Doppler ultrasound examination as simple, and noninvasive tool in prediction and assessment of severity of EV (Agha et al. in Dig Dis Sci 54(3):654–660, 2009). Our study was to assess the role of different Doppler indices of portal vein, hepatic and splenic arteries as a noninvasive tool for prediction of esophageal varices in cirrhotic patients.
Results
This prospective case control study was conducted on 100 cirrhotic liver patients and 100 of healthy volunteers as control group. Patients were subjected to clinical examination, upper gastrointestinal tract endoscopy, abdominal ultrasonography with duplex Doppler evaluation of different portal Doppler hemodynamic indices were done for each patient. The results revealed that portal vein diameter, hepatic artery pulsatility index, portal hypertensive index, portal vein flow velocity, portal congestion index have high sensitivity for prediction of EV. However, Splenic artery resistance index, hepatic artery resistance index HARI, liver vascular index and platelet count/spleen diameter have less sensitivity for prediction of EV.
Conclusion
Measuring the portal hemodynamic indices can help physicians as noninvasive predictors of EV in cirrhotic patients to restrict the need for unnecessary endoscopic screening especially when endoscopic facilities are limited.

Abstract
Background: Bleeding from esophageal varices is a life-threatening complication in cirrhosis. Screening endoscopy is recommended in cirrhotic patients to identify patients at risk of variceal hemorrhage, but this is an invasive procedure and has limitations. Therefore, thrombocytopenia has been proposed to predict the existence and grade of esophageal varices. The aim of the current study was to determine a correlation between platelet count and grades of esophageal varices in patients with liver cirrhosis. Methods: This cross-sectional study was conducted at the POF Hospital, Wah Cantt from 1 st October, 2017 to 30 th May, 2018. Newly diagnosed cases of cirrhosis having varices of any grade on endoscopy were included. Endoscopic findings of patients were standardized using Paquet grading system. On the basis of platelet count, patients were divided into four subgroups. Platelet count groups were correlated with grading of esophageal varices using Spearman rank correlations. Chi Square test was used to see association between the platelet count and grade of esophageal varices. Results: 110 patients were included in the study, 55.5% (n=61) were male. Mean age of the patients was 59.89±9.01 years. Platelet count was <50,000/uL in 35.5% patients, 50,000-99,000/uL in 26.4%, 100,000-150000 in 12.7%, and >150,000/uL in 25.5% patients. Grade I esophageal varices were found in 23.6% of patients, whereas grade II, III and IV were found in 24.5%, 33.6% and 18.2% of patients, respectively. Mean platelet count was 213884.62/mm 3 in patients with grade I varices, whereas it was 119518.52/mm 3, 58386.49/mm 3 and 21600.00/mm 3 in patients with grade II, III and IV varices, respectively (p=<0.0001). A significant negative correlation between platelet count and grades of esophageal varices was found (p<0.001). Conclusion: Platelet count can predict the grade of esophageal varices in cirrhotic patients. There is significant negative correlation between platelet count and grades of esophageal varices.

Liu H, Chen P, Jiang B, Li F, Han T. The value of platelet parameters and related scoring system in predicting esophageal varices and collateral veins in patients with liver cirrhosis. J Clin Lab Anal 2021; 35:e23694. [PMID: 33389784 PMCID: PMC7957998 DOI: 10.1002/jcla.23694] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2020] [Revised: 12/16/2020] [Accepted: 12/17/2020] [Indexed: 12/12/2022] Open
Abstract
Objective To explore the value of platelet parameters and related scoring system in predicting esophageal varices and collateral veins in patients with liver cirrhosis. Method A total of 94 patients with liver cirrhosis diagnosed in our hospital from March 2017 to July 2018 were divided into without esophageal varices group (NEV) and esophageal varices group (EV) into mild, moderate, and severe subgroups according to the results of general gastroscopy. The differences of biological indexes among different degrees of esophageal varices and collateral veins were analyzed, and the related factors of esophageal varices and collateral veins were analyzed. Results PLT count and PCT decreased gradually with the increase of esophageal varices in EV group. There were significant differences in PLT count and PCT, which were negatively correlated with the degree of collateral vein in esophageal collateral vein group. The maximum cross‐sectional diameter and mean diameter of esophageal collateral veins in EV group were wider than those in NEV group. Further study showed that the maximum cross‐sectional total diameter and mean diameter of esophageal collateral veins in severe esophageal varices group were wider than those in NEV group and mild esophageal varices group. Sequential Logistic regression analysis showed that PCT could effectively predict the existence of esophageal varices. Platelet parameters had no significant diagnostic value in predicting peri‐ECV and Para‐ECV. For platelet‐related FI, APRI, FIB‐4, King, Lok, GUCI, and FibroQ scoring systems, multivariate Logistic regression showed that FI, FIB‐4, Lok and FibroQ scoring systems could effectively predict the presence of EV and Para‐ECV (P<0.05), and its Lok Index is better than other rating systems, with AUROC values of 0.773 and 0.747, respectively. There is no significant predictive value for above scoring systems of peri‐ECV. Conclusions PCT and LOK index can effectively predict the existence of esophageal varices and para‐esophageal veins in patients with liver cirrhosis, and can be used as an effective filling method for common gastroscopy and endoscopic ultrasonography to detect EV and ECV in liver cirrhosis.

Abstract
BACKGROUND The diagnosis of esophageal varices (EV) is based on the findings of esophagogastroduodenoscopy (EGD), biopsy, and serum markers. Thus, noninvasive cost-effective tests through which high-risk EV children can be diagnosed are needed. PURPOSE This cross-sectional study aimed to identify the noninvasive markers for EV in children with liver cirrhosis. METHODS A total of 98 children with liver cirrhosis were evaluated in this study. The spleen size, platelet count, serum albumin, liver function test results, and risk scores were evaluated prior to endoscopy. The endoscopic investigations aimed to identify the presence of EV and red signs, and determine varices sizes. RESULTS Endoscopy revealed varices in 43 subjects (43.9%). The spleen size, platelet count, international normalized ratio, aspartate aminotransferase to platelet ratio index (APRI), platelet count to spleen size ratio, and risk score differed significantly between patients with and without EV on univariate analysis; however, the logistic regression analysis showed no differences, indicating that none of these parameters were independently associated with the presence of EV. CONCLUSION Platelet count, risk score, platelet count to spleen size, and APRI can be useful tools for the identification of highrisk patients with EV and might reduce the need for invasive methods like EGD.

Abstract
In the past decade, numerous studies have evaluated the roles of noninvasive methods for diagnosing or excluding varices and high-risk varices in patients with liver cirrhosis. The Baveno VI criteria recommend the use of a simple algorithm based on a liver stiffness measurement < 20 kPa through transient elastography and a platelet count > 150 × 109/L for ruling out high-risk varices in patients with compensated advanced chronic liver disease. A large number of studies have validated the clinical usefulness of Baveno VI criteria for excluding high-risk varices. Several strategies have been proposed to refine the Baveno VI criteria; however, currently there is no review to summarize the diagnostic accuracy and limitations of the Baveno VI criteria after extensive validation. In this review, we summarize the diagnostic accuracy and limitations of the Baveno VI criteria after extensive validation. We also discuss methods to refine these criteria.

Outcomes of oesophageal variceal bleeding among patients with atrial fibrillation: a propensity-matched analysis of a nationwide inpatient sample. Arch Med Sci Atheroscler Dis 2020; 5:e255-e262. [PMID: 33305064 PMCID: PMC7717439 DOI: 10.5114/amsad.2020.98949] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Accepted: 08/23/2020] [Indexed: 11/27/2022] Open
Abstract
Introduction We aimed to determine the influence of atrial fibrillation (AF) on mortality, morbidity, length of hospital stay, and resource utilisation in patients with oesophageal variceal bleeding (OVB). Material and methods The National Inpatient Sample database (2016 and 2017) was used for data analysis using the International Classification of Diseases, Tenth Revision codes to identify patients with the principal diagnosis of OVB and AF. We assessed the all-cause in-hospital mortality, morbidity, predictors of mortality, length of hospital stay (LOS), and total costs between propensity-matched groups of OVB with AF vs. OVB alone. Results We identified 80,325 patients with OVB, of whom 4285 had OVB with AF, and 76,040 had OVB only. The in-hospital mortality was higher in OVB with AF (OR = 1.4, 95% CI: 1.09–1.83; p < 0.001). OVB with AF had higher odds of sepsis (OR = 1.4, 95% CI: 1.1–1.8; p = 0.007), acute kidney injury (OR = 1.2, 95% CI: 1.12–1.32; p < 0.001), and mechanical ventilation (OR = 1.2, 95% CI: 1.12–1.32; p < 0.001). Advanced age (OR = 1.06, 95% CI: 1.05–1.07; p < 0.001), congestive heart failure (OR = 1.7, 95% CI: 1.3–2.3; p < 0.001), coronary artery disease (OR = 1.4, 95% CI: 1.03–1.92; p = 0.02), and sepsis (OR = 1.3, 95% CI: 1.06–1.70; p = 0.01) were identified as predictors of mortality in OVB with AF. Mean LOS (7.5 ±7.4 vs. 6.0 ±7.2, p < 0.001) and mean total costs ($25,452 vs. $21,109, p < 0.001) were also higher. Conclusions In this propensity-matched analysis, OVB with AF was associated with higher odds of in-hospital mortality, sepsis, acute kidney injury, and mechanical ventilation.

Abstract
Background and Aim Esophagogastroduodenoscopy (EGD) is the gold standard tool in both screening/diagnosis and management of varices in cirrhotic patients; however, its invasive nature may be uncomfortable to some patients, and in addition, it may be unavailable in some centers that cannot afford it. Therefore, to decrease the economic and physical burden on patients, multiple noninvasive clinical, laboratory, and radiological parameters are evaluated as triage screening predictors of varices before patients' referral to endoscopy. In this respect, we tried to evaluate the validity of portal vein velocity (PVV) as a noninvasive screening tool of esophageal varices (EV). Methods One hundred thirty‐five cirrhotic patients were consecutively enrolled in this cross‐sectional study. All patients were evaluated independently and blindly by EGD as the gold standard and then by Doppler ultrasound on portal vein (PV). Results Univariate regression showed significant coefficients for PVV, platelet (PLT), albumin, bilirubin, international normalized ratio (INR), portal vein diameter, and ascites; however, multivariable regression showed significant coefficients only for PVV, PLT, and albumin; (P = 0.000, 0.000, and 0.006, respectively). Area under the receiver operating characteristic curve (AUROC), sensitivity, specificity, LR+, and LR− values were then calculated and validated using bootstrap analysis. PVV was more accurate than other evaluated parameters (AUROC: 0.927 and P = 0.000). The most accurate rule out cutoff value for PVV was ≥19 cm/s with the sensitivity of 97% and LR− of 0.05. Conclusion PVV may be useful as a noninvasive triage test for selection of the high‐risk cirrhotic patients who should be referred to and could benefit from EGD. We could highlight using PVV to rule out EV at a cutoff value ≥19 cm/s, reserving EGD only for patients with the PVV value <19 cm/s.

Abstract
The assessment of non-invasive parameters for the prediction of large esophageal varices among patients with liver cirrhosisis is of utmost importance. In this study, non-invasive parameters for prediction of large esophageal varices were retrospectively evaluated. The presence of esophageal varices grade III and IV was classified as large esophageal varices positive while no varices or grade I and II were classified as large esophageal varices negative. There were 473 (90.09%) patients with ascites [mild 38 (8.03%), moderate 257 (54.33%) and severe 178 (37.63%)]. Frequency of esophageal varices was found to be higher (n=415, 79.04%). Whereas, large esophageal varices were found in 251 (47.81%) patients. The sensitivity, specificity, positive predicted value, negative predicted value and test accuracy of thrombocytopenia in predicting large esophageal varices were found to be 88.05%, 59.85%, 66.77%, 84.54% and 73.33% respectively. A significant association for large esophageal varices was observed for low platelet counts (AOR : 0.98, 95% CI : 0.97-0.99), high bilirubin level (AOR : 1.22, 95% CI : 1.07-1.39), ascites (AOR : 1.98, CI : 1.02-3.85) and Child score A (AOR : 0.26, 95% CI : 0.09-0.75) and Child Score B (AOR : 0.42, 95% CI : 0.28-0.61). In conclusion, low platelet count, high bilirubin level and ascites are found to be non-invasive predictive factor for large esophageal varices. J. Med. Invest. 66 : 248-251, August, 2019.

Abstract
Introduction Esophageal varices develop as a consequence of portal hypertension (PHT) in patients with chronic liver disease. Hence, screening of all cirrhotic patients with upper gastrointestinal endoscopy to detect the presence of significant esophageal varices implies a number of unnecessary endoscopies and has its limitation where such facilities are not available, especially in the rural part of country. Method Patients with either sex, aged between 18 and 60 years with diagnosis of cirrhosis were studied. Detailed history, physical examination along with relevant investigations were recorded and upper gastrointestinal endoscopy was done within 2-3 days of investigation. Esophageal varices were graded as I-IV, using the Paquet grading system and patients were classified dichotomously either as having large esophageal varices (LEV) group A (Grade III-IV) and no varices group B (grade I-II). Result A total of 50 patients with cirrhosis of liver were recruited in the study. Among hematological markers, only low platelet count was significantly associated with the presence of LEV (P value <0.05). None of the biochemical markers were found to be significantly associated with LEV. All the ultrasonographic parameters, i.e. spleen size, splenic vein size, portal vein size, and the presence of portosystemic collaterals were found to be significantly associated with the presence of LEV (P value <0.05). Conclusion Though upper gastrointestinal endoscopy remains the gold standard for the diagnosis of esophageal varices in cirrhotic patients,those patients at high risk of having LEV can be screened by using clinical, hematological, biochemical, and radiological markers.

Acoustic radiation forced impulse-based splenic prediction model using data mining for the noninvasive prediction of esophageal varices in hepatitis C virus advanced fibrosis. Eur J Gastroenterol Hepatol 2019; 31:1533-1539.

Abstract
BACKGROUND Esophageal varices (EV) are serious complications of hepatitis C virus (HCV) cirrhosis. Endoscopic screening is expensive, invasive, and uncomfortable. Accordingly, noninvasive methods are mandatory to avoid unnecessary endoscopy. Acoustic radiation forced impulse (ARFI) imaging using point shear wave elastography as demonstrated with virtual touch quantification is a possible noninvasive EV predictor. We aimed to validate the reliability of liver stiffness (LS) and spleen stiffness (SS) by an ARFI-based study together with other noninvasive parameters for EV prediction in HCV patients. Also, we aimed to evaluate the diagnostic performance of a new simple prediction model (incorporating SS) using data mining analysis. PATIENTS AND METHODS This cross-sectional study included 200 HCV patients with advanced fibrosis. Labs, endoscopic, ultrasonographic, LS, and SS data were collected. Their accuracy in diagnosing EV was assessed and a data mining analysis was carried out. RESULTS Ninety patients (22/46% of F3/F4 patients) had EV (39/30/18/3 patients had grade I/II/III/IV, respectively). LS and SS by ARFI showed high significance in differentiating not only patients with/without EV (P = 0.000 for both) but also correlated with the grading of varices (R = 0.31 and 0.45, respectively; P = 0.000 for both). Spleen longitudinal diameter (SD), splenic vein diameter (SVD), platelets to spleen diameter ratio, LOK index, and FIB-4 score were the best ultrasonographic and biochemical predictors for the prediction of EV [area under receiver operating characteristic (AUROC) 0.79, 0.76, 0.76, 0.74, and 0.71, respectively]. SS (using ARFI) had better diagnostic performance than LS for the prediction of EV (AUROC = 0.76 and 0.70, respectively). The diagnostic performance increased using data mining to construct a simple prediction model: high probability for EV if [(SD cm) × 0.17 + (SVD mm) × 0.06 + (SS) × 0.97] more than 6.35 with AUROC 0.85. CONCLUSION SS by ARFI represents a reliable noninvasive tool for the prediction of EV in HCV patients, especially when incorporated into a new data mining-based prediction model.

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.

Non-endoscopic predictors of esophageal varices in children with chronic liver disease and their utility in resource-constrained countries. Indian J Gastroenterol 2019; 38:310-316.

Abstract
BACKGROUND Although endoscopy is the standard diagnostic screening test to identify esophageal varices in patients with chronic liver disease (CLD), selective endoscopy in patients who are at higher risk of having varices may be cost-effective in a resource-constrained country. The aim of this prospective study was to identify non-endoscopic parameters that may predict the presence of varices, especially high-risk esophageal varices in children with CLD. METHODS From January 2016 through March 2018, consecutive children with CLD without a history of variceal bleeding were prospectively included. Esophagogastroduodenoscopy was done in all the children to detect and to grade esophageal varices. Both univariate and multivariate logistic regression analyses were done using SPSS version 22 to identify factors associated with esophageal varices. RESULTS The mean age of 84 children was 9.7 ± 3.2 years (male 44). Esophageal varices were present in 71.4% of children and 55% of them had large varices. On univariate analysis, low platelet count (< 100,000/mm3) and splenomegaly were found to be associated with the presence of esophageal varices (p = 0.006 and 0.001, respectively) and large varices (p = 0.03 and 0.01, respectively). On multivariate analysis, both low platelet count and splenomegaly were independent predictors for the presence of esophageal varices (respectively, OR 11.21, 95% CI 1.2-96.9; and OR 11.39, 95% CI 3.19-40.59). CONCLUSIONS Splenomegaly and low platelet count independently predict the presence of any grade of esophageal varices and can be used as screening tests to select children for endoscopy. This strategy may help in relieving medical, social, and economic costs in resource-constrained countries.

Abstract
BACKGROUND Current guidelines recommend screening of people with oesophageal varices via oesophago-gastro-duodenoscopy at the time of diagnosis of hepatic cirrhosis. This requires that people repeatedly undergo unpleasant invasive procedures with their attendant risks, although half of these people have no identifiable oesophageal varices 10 years after the initial diagnosis of cirrhosis. Platelet count, spleen length, and platelet count-to-spleen length ratio are non-invasive tests proposed as triage tests for the diagnosis of oesophageal varices. OBJECTIVES Primary objectives To determine the diagnostic accuracy of platelet count, spleen length, and platelet count-to-spleen length ratio for the diagnosis of oesophageal varices of any size in paediatric or adult patients with chronic liver disease or portal vein thrombosis, irrespective of aetiology. To investigate the accuracy of these non-invasive tests as triage or replacement of oesophago-gastro-duodenoscopy. Secondary objectives To compare the diagnostic accuracy of these same tests for the diagnosis of high-risk oesophageal varices in paediatric or adult patients with chronic liver disease or portal vein thrombosis, irrespective of aetiology.We aimed to perform pair-wise comparisons between the three index tests, while considering predefined cut-off values.We investigated sources of heterogeneity. SEARCH METHODS The Cochrane Hepato-Biliary Group Controlled Trials Register, the Cochrane Hepato-Biliary Group Diagnostic Test Accuracy Studies Register, the Cochrane Library, MEDLINE (OvidSP), Embase (OvidSP), and Science Citation Index - Expanded (Web of Science) (14 June 2016). We applied no language or document-type restrictions. SELECTION CRITERIA Studies evaluating the diagnostic accuracy of platelet count, spleen length, and platelet count-to-spleen length ratio for the diagnosis of oesophageal varices via oesophago-gastro-duodenoscopy as the reference standard in children or adults of any age with chronic liver disease or portal vein thrombosis, who did not have variceal bleeding. DATA COLLECTION AND ANALYSIS Standard Cochrane methods as outlined in the Cochrane Handbook for Diagnostic Test of Accuracy Reviews. MAIN RESULTS We included 71 studies, 67 of which enrolled only adults and four only children. All included studies were cross-sectional and were undertaken at a tertiary care centre. Eight studies reported study results in abstracts or letters. We considered all but one of the included studies to be at high risk of bias. We had major concerns about defining the cut-off value for the three index tests; most included studies derived the best cut-off values a posteriori, thus overestimating accuracy; 16 studies were designed to validate the 909 (n/mm3)/mm cut-off value for platelet count-to-spleen length ratio. Enrolment of participants was not consecutive in six studies and was unclear in 31 studies. Thirty-four studies assessed enrolment consecutively. Eleven studies excluded some included participants from the analyses, and in only one study, the time interval between index tests and the reference standard was longer than three months. Diagnosis of varices of any size. Platelet count showed sensitivity of 0.71 (95% confidence interval (CI) 0.63 to 0.77) and specificity of 0.80 (95% CI 0.69 to 0.88) (cut-off value of around 150,000/mm3 from 140,000 to 150,000/mm3; 10 studies, 2054 participants). When examining potential sources of heterogeneity, we found that of all predefined factors, only aetiology had a role: studies including participants with chronic hepatitis C reported different results when compared with studies including participants with mixed aetiologies (P = 0.036). Spleen length showed sensitivity of 0.85 (95% CI 0.75 to 0.91) and specificity of 0.54 (95% CI 0.46 to 0.62) (cut-off values of around 110 mm, from 110 to 112.5 mm; 13 studies, 1489 participants). Summary estimates for detection of varices of any size showed sensitivity of 0.93 (95% CI 0.83 to 0.97) and specificity of 0.84 (95% CI 0.75 to 0.91) in 17 studies, and 2637 participants had a cut-off value for platelet count-to-spleen length ratio of 909 (n/mm3)/mm. We found no effect of predefined sources of heterogeneity. An overall indirect comparison of the HSROCs of the three index tests showed that platelet count-to-spleen length ratio was the most accurate index test when compared with platelet count (P < 0.001) and spleen length (P < 0.001). Diagnosis of varices at high risk of bleeding. Platelet count showed sensitivity of 0.80 (95% CI 0.73 to 0.85) and specificity of 0.68 (95% CI 0.57 to 0.77) (cut-off value of around 150,000/mm3 from 140,000 to 160,000/mm3; seven studies, 1671 participants). For spleen length, we obtained only a summary ROC curve as we found no common cut-off between studies (six studies, 883 participants). Platelet count-to-spleen length ratio showed sensitivity of 0.85 (95% CI 0.72 to 0.93) and specificity of 0.66 (95% CI 0.52 to 0.77) (cut-off value of around 909 (n/mm3)/mm; from 897 to 921 (n/mm3)/mm; seven studies, 642 participants). An overall indirect comparison of the HSROCs of the three index tests showed that platelet count-to-spleen length ratio was the most accurate index test when compared with platelet count (P = 0.003) and spleen length (P < 0.001). DIagnosis of varices of any size in children. We found four studies including 277 children with different liver diseases and or portal vein thrombosis. Platelet count showed sensitivity of 0.71 (95% CI 0.60 to 0.80) and specificity of 0.83 (95% CI 0.70 to 0.91) (cut-off value of around 115,000/mm3; four studies, 277 participants). Platelet count-to-spleen length z-score ratio showed sensitivity of 0.74 (95% CI 0.65 to 0.81) and specificity of 0.64 (95% CI 0.36 to 0.84) (cut-off value of 25; two studies, 197 participants). AUTHORS' CONCLUSIONS Platelet count-to-spleen length ratio could be used to stratify the risk of oesophageal varices. This test can be used as a triage test before endoscopy, thus ruling out adults without varices. In the case of a ratio > 909 (n/mm3)/mm, the presence of oesophageal varices of any size can be excluded and only 7% of adults with varices of any size would be missed, allowing investigators to spare the number of oesophago-gastro-duodenoscopy examinations. This test is not accurate enough for identification of oesophageal varices at high risk of bleeding that require primary prophylaxis. Future studies should assess the diagnostic accuracy of this test in specific subgroups of patients, as well as its ability to predict variceal bleeding. New non-invasive tests should be examined.

Platelet Count to Spleen Diameter Ratio for the Diagnosis of Gastroesophageal Varices in Liver Cirrhosis: A Systematic Review and Meta-Analysis. Gastroenterol Res Pract 2017; 2017:7407506. [PMID: 28270848 PMCID: PMC5320338 DOI: 10.1155/2017/7407506] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/03/2016] [Accepted: 11/30/2016] [Indexed: 12/15/2022] Open
Abstract
Platelet count to spleen diameter ratio (PSR) was studied extensively as a noninvasive method of diagnosis for varices. The present study aimed to systematically assess the performance of PSR in the diagnosis of varices. PubMed, EMBASE, and article references were searched. The summary receiver operating characteristic curves (AUSROCs), sensitivities, specificities, positive and negative likelihood ratio, and diagnostic odds ratio were calculated. The heterogeneity, quality, and publication bias of studies were evaluated. Subgroup and sensitivity analyses were performed. A total of 49 papers were included. The AUSROCs of PSR for any varices and high-risk varices were 0.8719 and 0.8132, respectively. The summary sensitivities of PSR for any varices and high-risk varices were 0.84 and 0.78, respectively. The summary specificities of PSR for any varices and high-risk varices were 0.78 and 0.67, respectively. The AUSROC of PSR for any varices at the threshold of 909 was 0.8867. The AUSROC of PSR for any varices in viral liver cirrhosis was 0.8675. The overall quality of studies was moderate. Significant heterogeneity and publication bias existed in the study. In conclusion, PSR can be used to identify varices in liver cirrhosis. PSR had a high sensitivity in viral liver cirrhosis.

Abstract
BACKGROUND/AIMS Cirrhosis and portal hypertension are characterised by a hyperdynamic circulation, which is independently associated with variceal size. Non-invasive techniques for measurement of systemic haemodynamics are now available. The aim of the study was to prospectively assess the accuracy of systemic haemodynamics measured non-invasively for the detection of oesophageal varices in cirrhotic patients as compared to other currently available non-invasive methods. METHODS In a study of 29 cirrhotic patients, systemic haemodynamics were studied non-invasively using the Finometer® (mean arterial pressure (MAP), cardiac output (CO)/index, heart rate (HR), peripheral vascular resistance) and portal pressure was assessed by hepatic venous pressure gradient. Sensitivity, specificity, predictive values and area under the receiver operating characteristic (ROC) curves were assessed for predicting presence of varices and large oesophageal varices. Results were compared to child's classification, platelet/spleen ratio and ALT/AST ratios as predictors of the presence of large varices. RESULTS Using finometry large oesophageal varices were correctly predicted in 83% of patients compared to other non-invasive techniques (range 66-76%). CONCLUSIONS Non-invasive assessment of systemic haemodynamics using finometry could aid the identification of patients who do not immediately require variceal surveillance reducing the numbers of endoscopies and ensuring services are provided to those most likely to benefit.

Abstract
Japan Gastroenterological Endoscopy Society (JGES) has compiled a set of guidelines for endoscopic management of non-variceal upper gastrointestinal bleeding using evidence-based methods. The major cause of non-variceal upper gastrointestinal bleeding is peptic gastroduodenal ulcer bleeding. As a result, these guidelines mainly focus on peptic gastroduodenal ulcer bleeding, although bleeding from other causes is also overviewed. From the epidemiological aspect, in recent years in Japan, bleeding from drug-related ulcers has become predominant in comparison with bleeding from Helicobacter pylori (HP)-related ulcers, owing to an increase in the aging population and coverage of HP eradication therapy by national health insurance. As for treatment, endoscopic hemostasis, in which there are a variety of methods, is considered to be the first-line treatment for bleeding from almost all causes. It is very important to precisely evaluate the severity of the patient's condition and stabilize the patient's vital signs with intensive care for successful endoscopic hemostasis. Additionally, use of antisecretory agents is recommended to prevent rebleeding after endoscopic hemostasis, especially for gastroduodenal ulcer bleeding. Eighteen statements with evidence and recommendation levels have been made by the JGES committee of these guidelines according to evidence obtained from clinical research studies. However, some of the statements that are supported by a low level of evidence must be confirmed by further clinical research.

Abstract
OBJECTIVE At present, there is no perfect noninvasive method to assess portal hypertension and esophageal varices. Early predicting esophageal varices can provide evidence for managing cirrhotic patients. We aimed to further investigate von Willebrand factor (vWF) as a noninvasive predictor of portal hypertension, especially of esophageal varices. MATERIAL AND METHODS A total of 60 hepatitis B patients with cirrhosis and 45 healthy subjects were enrolled in this study. Levels of six markers were examined. All patients underwent hepatic venous pressure gradient (HVPG) and esophagogastroduodenoscopy. We evaluated the performance of six factors for diagnosis of portal hypertension and esophageal varices. The vWF levels in liver tissues were observed by immunohistochemistry. Correlations between the level of vWF in liver tissues and HVPG and between levels of vWF in tissues and plasma were examined. RESULTS Cutoff values of plasma vWF (1510.5 mU/mL and 1701 mU/mL) showed high positive predictive value (PPV, 90.2% and 87.5%) in predicting clinically significant portal hypertension and severe portal hypertension. Cutoff values of vWF (1414 mU/ml and 1990 mU/mL, PPV 90.3% and 86.3%, respectively) were provided to detect the presence and degree of esophageal varices. Linear correlations were observed between levels of vWF in liver tissues and HVPG (r(2) = 0.552, p < 0.001) and between the level of vWF in liver tissues and in plasma (r(2) = 0.461, p < 0.001). CONCLUSION The vWF is a noninvasive predictor of portal hypertension and esophageal varices in hepatitis B patients with cirrhosis. Increased levels of vWF in liver tissues may induce the elevated plasma vWF levels, but molecular mechanism is needed for further study.

Abstract
Owing to the high prevalence of various chronic liver diseases, cirrhosis is one of the leading causes of morbidity and mortality worldwide. In recent years, the development of non-invasive tests of fibrosis allows accurate diagnosis of cirrhosis and reduces the need for liver biopsy. In this review, we discuss the application of these non-invasive tests beyond the diagnosis of cirrhosis. In particular, their role in the selection of patients for hepatocellular carcinoma surveillance and varices screening is highlighted.

Abstract
Predicting the presence and the grade of varices by non-invasive methods is likely to predict the need for prophylactic beta blockers or endoscopic variceal ligation. The factors related to the presence of varices are not well-defined. Therefore, the present study has been undertaken to determine the appropriateness of the various factors in predicting the existence and also the grade of esophageal varices. Patients with diagnosis of liver cirrhosis due to hepatitis C or B were included in a retrospective study between January 2001 and January 2010. All the patients underwent detailed clinical evaluation, appropriate investigations, imaging studies (ultrasound with Doppler) and endoscopy at our center. Five variables considered relevant to the presence and grade of varices were tested using univariate and multivariate analysis (logistic regression). Three hundred and seventy two patients with viral liver cirrhosis were included, with 192 (51.6%) males. Platelet count and abundance of ascites were significantly associated with the presence of esophageal varices. However, abundance of ascites, prothrombin time, diameter of the spleen and portal vein were significantly associated with a large varice. In multivariate analysis, platelet count inferior to 100000 was associated with presence of varices (p = 0.04) and only abundance of ascites was associated with large varice. Low Platelet count (< or equal 100000) is associated with the presence of varices in viral cirrhotic patients and abundance of ascites is correlated with the presence of large varices.

Abstract
AIM: To investigate risk factors for esophageal variceal bleeding (EVB) in patients with liver cirrhosis.
METHODS: Clinical data for 178 esophageal varices patients with liver cirrhosis were analyzed retrospectively. The patients were divided into either an EVB group (n = 118) or a non-EVB group (n = 60). Twenty-four potential factors were analyzed by t-test, chi-square test and multivariate Logistic regression analysis to identify the risk factors for EVB.
RESULTS: Red blood cell (RBC) count, hemoglobin (Hb), albumin (ALB), prothrombin time activity (PTA), Child-Pugh class B and C hepatic function, history of EVB, portal vein width, splenic vein width, splenic thickness, and red-color sign demonstrated statistically significant differences between the EVB group and the non-EVB group. Multivariate Logistic regression analysis showed and Hb (OR = 0.204, P = 0.001) and ALB (OR = 0.126, P = 0.000) were correlated negatively with EVB, while history of EVB (OR = 3.622, P = 0.01), portal vein width (OR = 2.619, P = 0.032) and red-color sign (OR = 4.647, P = 0.001) were correlated positively with EVB.
CONCLUSION: Anemia, hypoalbuminemia, history of EVB, extended portal vein width, and positive red-color sign are independent risk factors for EVB.

Abstract
OBJECTIVE The aim of this study was to identify ultrasonographic predictors of esophageal varices (EVs) in children and adolescents with chronic liver disease (CLD) and extrahepatic portal venous obstruction (EHPVO). METHODS This study evaluates 53 patients younger than 20 years with CLD or EHPVO and no history of bleeding or prophylactic EVs treatment. They were divided into 2 groups: group I (35 with CLD) and group II (18 with EHPVO). Splenorenal shunt (SS), gallbladder wall varices, gallbladder wall thickening (GT), and lesser omental thickness (LOT) were compared with the presence of EVs, gastric varices, and portal hypertensive gastropathy (PHG). Univariate (χ² test, Fisher exact test, and Wilcoxon signed rank test) and multivariate (logistic regression) analyses were performed. The area under the receiver operating curve was calculated. RESULTS EVs were observed in 48.5% of patients with CLD and in 83.3% of patients with EHPVO. SS (P = 0.0329) and LOT (P = 0.0151) predicted EV among patients with CLD. A median of 5.3 mm of LOT was considered a predictor of EVs among these patients. Multivariate analysis showed SS as an independent predictor of EVs in patients with EHPVO (odds ratio 15). Gallbladder varices (P = 0.0245) and GT (P = 0.0289) predicted EVs among patients with EHPVO. PHG occurred more often among patients with CLD who had SS (P = 0.0384) and greater LOT (P = 0.0226). CONCLUSIONS SS and a greater LOT were indicative of EV among children and adolescents with CLD. Gallbladder varices and GT were indicative of EVs among patients with EHPVO. SS and a greater LOT were indicative of PHG among patients with CLD.

Abstract
BACKGROUND AND STUDY AIMS Variceal bleeding is a frequent and life-threatening complication of portal hypertension. The aim of this study was to evaluate multidetector computed tomographic (MDCT) oesophagography as an alternative to endoscopy for screening oesophageal varices (EVs) and predicting bleeding risk. PATIENTS AND METHODS A total of 137 cirrhotic patients underwent MDCT followed by endoscopy and EVs were graded independently. The screening ability of CT for EV was evaluated by comparing the grades of EV at CT and at endoscopy. Prediction of bleeding risk by CT was determined by correlating the CT variceal grades, diameters and palisade vein dilatation with the endoscopic red colour (RC) sign. Extra-oesophageal findings were assessed by CT. Patients' acceptance for both examinations were compared. RESULTS At endoscopy, 47 (34%) patients had grade 0 EV, 52 (38%) patients had grade 1 EV, 29 (21%) patients had grade 2 EV and nine (7%) patients had grade 3 EV. The sensitivity, specificity, positive and negative predictive values and accuracy of CT oesophagography for defining EV in all grades were 99%, 98%, 99%, 98% and 99%, respectively. The MDCT variceal grades, diameters and palisade vein dilatation were correlated with the severity of the RC sign. Important extra-oesophageal findings were determined by CT only. The acceptance of patients for CT oesophagography was significantly more than that for endoscopy (p<0.001). CONCLUSION MDCT is a reliable, preliminary or adjunctive method that can be used for routine screening for EVs and the prediction of variceal bleeding.

Abstract
BACKGROUND Bleeding from esophageal varices is a major potential concern during transesophageal echocardiography (TEE) in patients with cirrhosis of the liver. As there are limited data on its risk in these patients, this was retrospectively assessed at our institution. METHODS The hospital electronic medical record database at our university affiliated teaching hospital was searched for all patients with esophageal varices undergoing TEE from 2000 to 2012 and patient charts were reviewed for procedure-related bleeding complications. RESULTS Twenty-four patients with esophageal varices were found (18 men, 57 ± 14 years). Nine patients had grade 2 esophageal varices, 15 patients had grade 1 varices, and 12 patients had portal hypertensive gastropathy. Alcoholic liver disease (9) and hepatitis C (8) were the most common etiologies of the cirrhosis with an average MELD score of 15. The most common indication for TEE was for possible endocarditis (15). Medications potentially increasing bleeding risk included warfarin in 2 and aspirin in 7 patients. Twelve patients were taking β-blockers for portal hypertension. There were no immediate bleeding complications and none of these patients were readmitted with bleeding. CONCLUSIONS TEE can be performed without serious bleeding risk in patients with grade 1 or 2 esophageal varices.

Abstract
BACKGROUND Platelet count/spleen diameter ratio (PSR) is a non-invasive method for the assessment of esophageal varices (EV), developed as an alternative to endoscopy. AIM To assess the performance of PSR for diagnosis of EV using meta-analysis. METHODS PubMed, EMBASE, the Cochrane Library, ISI web of Knowledge, China National Knowledge Infrastructure, and article references were searched. We included studies using endoscopy as a reference standard, with the data necessary to calculate the true and false positive, true and false negative diagnostic results of PSR for EV. The quality of the studies was rated with the QUADAS tool. The hierarchical summary receiver operating characteristic (HSROC) was used to examine the PSR accuracy for the diagnosis of EV. Heterogeneity was explored using meta-regression. Clinical utility of PSR for EV was evaluated by a Fagan plot. RESULTS In 20 studies (n = 3,063), the HSROC of the PSR for EV was 0.95 at various thresholds. At the threshold of 909, the summary sensitivities and specificities were 0.92 (95% CI, 0.79-0.97) and 0.87 (95% CI, 0.76-0.93), respectively. The HSROC was also 0.95 at the threshold of 909. If PSR was below 909 for EV ("positive" result), the post-test probability (if pre-test probability was 50%) was 87%, while if PSR was at or over 909 ("negative" result), the post-test probability was only 9%. PSR also had a high accuracy in diagnosis of EV in patients with compensated cirrhosis. CONCLUSIONS PSR can identify EV in cirrhosis with a high accuracy. Application of this index may decrease the need for endoscopy among cirrhotic patients.

Improving survival in decompensated cirrhosis. Int J Hepatol 2012; 2012:318627. [PMID: 22811919 PMCID: PMC3395145 DOI: 10.1155/2012/318627] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/05/2012] [Revised: 04/30/2012] [Accepted: 05/03/2012] [Indexed: 12/11/2022] Open
Abstract
Mortality in cirrhosis is consequent of decompensation, only treatment being timely liver transplantation. Organ allocation is prioritized for the sickest patients based on Model for End Stage Liver Disease (MELD) score. In order to improve survival in patients with high MELD score it is imperative to preserve them in suitable condition till transplantation. Here we examine means to prolong life in high MELD score patients till a suitable liver is available. We specially emphasize protection of airways by avoidance of sedatives, avoidance of Bilevel Positive Airway Pressure, elective intubation in grade III or higher encephalopathy, maintaining a low threshold for intubation with lesser grades of encephalopathy when undergoing upper endoscopy or colonoscopy as pre transplant evaluation or transferring patient to a transplant center. Consider post-pyloric tube feeding in encephalopathy to maintain muscle mass and minimize risk of aspiration. In non intubated and well controlled encephalopathy, frequent physical mobility by active and passive exercises are recommended. When renal replacement therapy is needed, night-time Continuous Veno-Venous Hemodialysis may be useful in keeping the daytime free for mobility. Sparing and judicious use of steroids needs to be borne in mind in treatment of ARDS and acute hepatitis from alcohol or autoimmune process.

Galal GM, Amin NF, Abdel Hafeez HA, El-Baz MAH. Can serum fibrosis markers predict medium/large oesophageal varices in patients with liver cirrhosis? Arab J Gastroenterol 2011; 12:62-7. [PMID: 21684475 DOI: 10.1016/j.ajg.2011.04.003] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2010] [Revised: 03/15/2011] [Accepted: 04/06/2011] [Indexed: 12/26/2022]
Abstract
BACKGROUND AND STUDY AIMS Non-invasive predictors of medium/large oesophageal varices (LOVs) could reduce the number of screening endoscopies. As portal hypertension is a consequence of liver fibrosis, serum fibrosis markers were evaluated together with other variables as possible non-invasive predictors of medium OV/LOV. PATIENTS AND METHODS A total of 154 cirrhotic patients with splenomegaly and 30 healthy control subjects were recruited in a prospective study in two gastroenterology centres in Upper Egypt. Clinical parameters assessed included Child-Pugh class, liver size and ascites. Laboratory parameters included complete blood count, liver function tests, and aspartate aminotransferase (AST)/platelet ratio. Transforming growth factor-β(1) (TGF-β(1)), alpha(2) macroglobulin (A(2)M) and hyaluronic acid (HA) were assayed. Ultrasonographic examination was done for assessment of liver span, portal vein diameter and detection of minimal ascites. Oesophageal varices were diagnosed and graded by oesophagogastroduodenoscopy. RESULTS Fifty-four patients (35%) had no or small varices and 100 (65%) patients had medium OV/LOV by endoscopy. On multivariate analysis, the independent predictors of medium OV/LOV were the presence of ascites (β=0.258, p=0.047) and serum HA (β=0.449, p=0.009). The receiver operating characteristic curve for HA showed the area under the curve to be 0.916. The sensitivity, specificity, positive and negative predictive values and diagnostic accuracy of HA at a cut-off value of 207μgl(-1) were 94%, 77.8%, 88.7%, 87.5% and 88.3%, respectively. CONCLUSIONS The presence of ascites and serum HA level higher than 207μgl(-1) can predict the presence of medium OV/LOV in cirrhotic patients. This would help physicians to identify patients who would most likely benefit from screening endoscopy and thus, reduce costs and discomfort from unnecessary endoscopic procedures.
