Non-alcoholic fatty liver disease (NAFLD) is defined as accumulation of fat in the liver which is not related to either alcohol excess or other causes such viral infection, immune-mediated, or medication related which can lead to fibrosis and later-on, cirrhosis. Over the last years NAFLD related liver cirrhosis has become the commonest cause of chronic liver disease worldwide. Portal hypertension is the major complication caused by increased splanchnic blood flow which leads to development of oesophageal varices (OV). Almost all of the patients with portal hypertension can develop OV sometime in their life and one third of those will bleed, hence identifying the presence of OV is a an important aspect of diagnostic workup of these patients with portal hypertension. Upper digestive camera test/endoscopy is the only means to diagnose and grade OV but endoscopy is an invasive procedure and its cost effectiveness for screening is also questionable. These limitations and the ever-increasing workload on endoscopy units has led many researchers to identify some parameters that can non-invasively diagnose OV. Researchers have proposed use of platelet count/spleen diameter ratio, liver stiffness on Fibroscan among many non-invasive tools to predict OV in patients with portal hypertension with success. Recently criteria proposed in Baveno VI conference, (Baveno-IV Criteria) recommended that screening endoscopy can be avoided in patients with compensated advanced chronic liver disease (cACLD) with liver stiffness measurement (LSM) less than 20 kPa and a platelet count more than than 150,000/μL with an expanded Baveno-IV criteria suggesting platelet count >110 × 109 cells/L and LSM <25 kPa can spare even more endoscopies with a risk of missing varices needing treatment (VNT) being minimal.
In the Western world, liver cirrhosis is a significant issue. Acute variceal bleeding (AVB) is a considerable complication of cirrhosis associated with high mortality. Still, the combination of endoscopic variceal ligation and terlipressin-like treatment decreases the risks of rebleeding and mortality. This therapy with terlipressin usually was used for 72 hours. However, there are some studies demostrating that using terlipressin for 24 hours could control variceal bleeding with fewer side effects.
Patients with chronic liver disease (CLD) are at risk of developing clinically significant portal hypertension (CSPH). In the Baveno VI consensus a new term "compensated advanced chronic liver disease (cACLD)'' has been proposed to better reflect that the spectrum of severe fibrosis and cirrhosis is a continuum in asymptomatic patients. Liver stiffness by TE is sufficient to suspect cACLD in asymptomatic subjects with known causes of CLD. TE values <10 kPa in the absence of other known clinical signs rule out cACLD; values between 10 and 15 kPa are suggestive of cACLD but need further test for confirmation; values >15 kPa are highly suggestive of cACLD. Patients with a liver stiffness <20 kPa and with a platelet count >150,000 have a < 5 % risk of having varices requiring treatment, and can avoid screening endoscopy. SSM can also predict the presence of CSPH and varices requiring treatment. Some studies have shown superiority of splenic stiffness over liver stiffness in predicting varices requiring treatment likely attributable to the better performance of SSM compared with LSM in more severe portal hypertension because it reflects better the hemodynamic component of portal hypertension. However, there are few studies on NAFLD and most are on viral hepatitis related cACLD. Moreover, very few studies are published on splenic stiffness from Indian subcontinent. Similarly baseline HVPG is an important predictor of disease progression patients of NAFLD related cACLD, but requires invasive hepatic vein catheterization. Hence, we intend to do the study assessing diagnostic utility of splenic and liver stiffness in predicting varices needing treatment in NAFLD related cACLD and compare from other noninvasive markers and its correlation with HVPG.
Monitoring and Assessment: Transient Elastography will be performed in morning hours using the FibroScan apparatus (Echosens), which consists of a 5-MHz ultrasound transducer probe mounted on the axis of a vibrator. The tip of the transducer (M-or XL probe) will be covered with a drop of gel and placed perpendicularly in the intercostal space, with the patient lying in dorsal decubitus position with the right arm in the maximal abduction. Under control, in time motion and in A-mode, the operator will choose a liver portion within the right liver lobe, at least 6-cm thick and free of large vascular structures, and the gallbladder. Liver stiffness (LS) will be measured on a cylinder of hepatic tissue of 1 cm of diameter and 4 cm of length. For assessing the splenic stiffness (SS), the patient will be in supine position with left arm in maximum abduction. Ultrasonography will be used to identify and locate the spleen parenchyma, to choose the right place for SS measurement, and to measure the spleen diameter (long axis). Transducer will be placed in the left intercostal spaces, with location indicated by the ultrasound. A median value of 10 successful acquisitions, expressed in kPa, will be kept as a representative of the LS and SS measurements. The LS and SS measurement failure will be recorded when no value will be obtained after at least 10 shots. The results will be considered unreliable in the following circumstances: valid shots fewer than 10, success rate < 60%, or interquartile range / LS >30 %. Liver and splenic stiffness, LSPS score (LS measurement × spleen diameter / platelet count), Platelet count to spleen diameter ratio (PSR) will be calculated. Patient will also undergo upper g.i. endoscopy on same day. HVPG and TJLB will be done if indicated. The study will assess whether the stiffness scores correlate with presence of esophageal varices. Optimum cutoffs will be calculated for predicting the presence of esophageal varices. - Study design: A Cross-Sectional Study - Study period: 12 months - Sample size with justification: Consecutive Patients of ACLF from approval of study to 12 months. ACLF patients will be screened and eligible patients will be taken in to the study. - Intervention: Patients of ACLF will undergo upper g.i. endoscopy, liver and splenic stiffness measurement. HVPG and TJLB will be done in the patients only if clinically indicated.
The investigators aimed to verify the efficacy and safety of nadroparin calcium warfarin sequential (NWS) anticoagulation therapy after endoscopic therapy in PVT patients with cirrhosis and AVB.
This study is a retrospective, multi-center and observational clinical study. Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The fifth medical center of PLA General Hospital, Zhongshan Hospital, Fudan University, Shanghai, Nanjing Drum Tower Hospital affiliated Nanjing University Medical School and Xiangyang Central Hospital will participate in the study. Investigators would like to provide evidence-based medical evidence by evaluating and comparing the efficacy and safety of endoscopic ultrasound (EUS)-guided coil embolization combined with endoscopic cyanoacrylate injection and balloon-occluded retrograde transvenous obliteration (BRTO) in the treatment of gastric varices (GV) with spontaneous portosystemic shunt (SPSS). Between January 2014 and December 2020, patients with GV secondary to portal hypertension admitted to a tertiary medical center, are enrolled consecutively according to the following criteria: (1) age≥18 years; (2)endoscopic examination confirms the presence of GV; (3) CTA of the portal system and EUS revealed the presence of SPSS, the diameter was between 5 mm to 15 mm; (4) treatment with EUS-guided coil combined with endoscopic cyanoacrylate injection or BRTO. Exclusion criteria are as follows: (1)malignant tumors; (2) hepatic encephalopathy, hepatorenal syndrome or multiple organ failure; (3) previously received esophagus or stomach surgery; (4) pregnant. Investigators will collect patients' data of baseline character, treatment, postoperative and follow-up. All patients will be followed up until the progress of the disease or the end of the study. And rebleeding, ectopic embolism, survival, and sequential treatment will be recorded during the follow-up period. The primary endpoint are five-day rebleeding rate and six-week mortality rate. The secondary endpoint are: technical success rate, incidence of ectopic embolism, eradication of GV, one-year rebleeding rate, one-year mortality rate, and cost-effectiveness ratio. All data and information use SPSS statistical software to complete all statistical analysis.
