Active clinical trials for "Esophageal and Gastric Varices"

The purpose of the study is to access the accuracy of the PillCam Eso capsule in identifying the presence of suspected esophageal disease in patients undergoing surveillance or screening for esophageal disease by standard endoscopy

The aim of this study is to evaluate patient and consultant experiences with phone consultations for endoscopy-related outpatient appointments during the COVID-19 outbreak.

Assessment of blood ammonia level as a non-invasive predictor for presence of EV and risk of bleeding

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 aim of the study is to develop and validate a new noninvasive method based on routine examination during clinical practice for predicting high risk esophageal varices in cirrhosis.

Liver cirrhosis is caused by chronic liver diseases, varices exist in 30 - 60% of patients with liver cirrhosis. Variceal bleeding is one of the most important complications of cirrhosis, accelerating the progression of decompensation to a stage at which the patient is at an extremely high risk of death. Endoscopy is the gold standard for the diagnosis of varices, However, periodic endoscopic screening in all cirrhotic patients might unnecessarily induce an invasive and expensive procedure, ultimately increasing not only the medical workload of endoscopy units, but also the financial burden of patients. To avoid unnecessary endoscopy in low- risk patients, some simple, non-invasive and accurate tests have been developed to identify EVs. Such as Transient elastography (TE) , which is a noninvasive tool that measures liver stiffness (LS) correlating to liver fibrosis stage. Moreover, the LS-spleen size-to-platelet ratio score (LSPS), which is a combination of three simple examination methods (LS, spleen size and platelet count) has been established to accurately predict EVs in patients with cirrhosis. Therefore, investigators design this cross-sectional study to assess these non-invasive tests in predicting the presence of EVs in patients with cirrhosis.

This study is intended to include 20 patients with esophageal varices caused by liver cirrhosis who were admitted to the first affiliated hospital of nanjing medical university from May 2019, and randomly select 8 patients with gastric polyps as the control group.General clinical data, imaging data, endoscopic data and laboratory indicators were collected.Electrogastrogram (EGG) and Heart Rate Variability (HRV) were performed before and 24 hours after operation in patients with cirrhotic esophageal varices, and the dyspepsia scale was filled out.Electrogastrogram (EGG) and cardiac variability (HRV) were performed in patients with gastric polyps 24 hours before and after surgery, and the dyspepsia scale was filled.EGG uses the surface electrode to record gastric myoelectric activity, and evaluates the patient's gastric rhythm by normal slow wave ratio, overspeed ratio, overslow ratio, and rhythm disorder ratio.The HRV evaluates the balance state of the patient's autonomic nervous system with High Frequency (HF)/Low Frequency (LF).SPSS software was used for paired sample analysis of experimental results.

The goal of this compassionate access program is to provide early access to REP 2139-Mg for patients with HBV mono-infection or HBV / HDV co-infection who either have advanced (decompensated) cirrhosis or who have failed to response to other other antiviral agents either approved or under development and who are in danger of progressing to decompensated cirrhosis. This compassionate access program will provide access to a once weekly regimen of subcutaneously (SC) administered REP 2139-Mg for a period of 48 weeks with the goal of achieving functional cure of HDV and or HBV, with the reversal of liver disease in the absence of antiviral therapy. The safety, tolerability and efficacy of SC REP 2139-Mg will be monitored during and after therapy

Esophageal capsule endoscopy is sedation-less alternative to upper endoscopy for evaluating esophageal lesions and potentially other upper gastrointestinal lesions. The purpose of this study was to determine whether esophageal capsule endoscopy is convenient and accurate as upper endoscopy for detection of esophageal varices and related lesions.
