NCT ID: NCT05515861 Not yet recruiting - Liver Cirrhosis Clinical Trials

Evaluation of EUS in Preventing Rebleeding After Endoscopic Cyanoacrylate Injection for Gastric Varices

Start date: September 2022
Phase: N/A
Study type: Interventional

The aim of this study is to explore whether using endoscopic ultrasound (EUS) to assess gastric varices (GV) and giving additional treatment according to the diameter and blood flow of residual after endoscopic cyanoacrylate injection for GV can reduce the rate of GV rebleeding, mortality, the risk of adverse events, and cost-effectiveness. This study is a multicenter prospective, open-label, randomized controlled study, including 5 study centers: Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The Southwest Hospital of Army Medical University, Affiliated Hospital of Zunyi Medical University and Shanxi Coal Center Hospital. The total sample size is 150 patients, with 75 patients in the EUS evaluation group and 75 patients in the control group, respectively. The patients who meet the inclusion and exclusion criteria are randomly assigned to EUS evaluation group and control group by using block randomization. The EUS evaluation group uses EUS to observe the diameter and blood flow of residual variceal veins after endoscopic cyanoacrylate injection for GV to evaluate the embolization effect. Endoscopic cyanoacrylate injection is performed again if the diameter of variceal vein is larger than 5 mm and with blood flow signal. After the injection, the blood flow signal is confirmed disappear by EUS. The control group return to the ward after endoscopic cyanoacrylate injection, without EUS evaluation. During the study, the patients are followed up for at least 12 months, and they are requested to return to the hospital for follow-up at 1 month, 3 months, 6 months and 12 months after the treatment, respectively. The data of baseline, treatment, postoperative and follow-up of the two groups are need to collect. The primary outcome of this study is rebleeding rate. Secondary outcomes are eradication rate of GV, mortality rate, retreatment, and cost-effectiveness.

NCT ID: NCT05508581 Not yet recruiting - Varicose Veins Clinical Trials

Microwaves Ablation of Varicose Veins

Start date: October 15, 2023
Phase: N/A
Study type: Interventional

Lower-limb varicose veins (VVs) are the most common of vascular diseases and affect up to one-third of the population, severely affecting the quality of life (QoL) of patients. In past decades, traditional surgical ligation and stripping were the gold standard therapy for patients with VVs; however, traditional methods have demonstrated high complication and recurrence rates. Thus, the practices are moving toward minimally invasive alternatives.

NCT ID: NCT05500625 Not yet recruiting - Gastric Varix Clinical Trials

Endoscopic Ultrasound-guided Coil With Cyanoacrylate Injection Versus Balloon-Occluded Retrograde Transvenous Obliteration in Managing Patients With Gastric Varices

Start date: August 30, 2022
Phase: N/A
Study type: Interventional

Gastrointestinal bleeding is a common complication of liver cirrhosis which caused by esophageal and gastric varices. The risk of bleeding from gastric varices is relatively low. However, the bleeding is usually significant and severe. Current guidelines recommend endoscopic glue injection as the first line of treatment for gastric variceal bleeding. Although this technique has been shown to be effective, it is associated with many severe adverse events including systemic embolization, fever, chest pain, and even death. The rate of hemostasis has been reported to be as high as 91-100% but the rebleeding rate from gastric varices still present. Endoscopic ultrasound (EUS) guided therapy has recently been introduced as a more effective and safer option than endoscopic therapy for gastric varices. EUS-guided therapy includes EUS guided Cyanoacrylate injection alone or in combination with EUS-guided coiling. It offers the advantage of directly visualizing the varices and delivering targeted therapy. A standard endoscopic examination only allows the evaluation of superficial varices. The use of Endoscopic ultrasound facilitates evaluation of peri-gastric and perforating vessels, which are directly involved in variceal development. EUS also facilitates accurate placement of the coil and preserves the naturally formed splenorenal shunt. Balloon-occluded retrograde transvenous obliteration(BRTO) has been reported to achieve satisfactory bleeding control rates for isolated gastric varices with High hemostasis rates and low rebleeding rate. Despite all these promising results, there are scarce studies describing and comparing the efficacy of EUS-guided therapy and BRTO in patients with gastric varices. Further prospective comparative studies are needed.

NCT ID: NCT05485714 Completed - Esophageal Varices Clinical Trials

Non-invasive Prediction of Esophageal Varices in Patients With Non-Alcoholic Fatty Liver Disease With Advanced Fibrosis

Start date: October 5, 2022
Phase:
Study type: Observational

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.

NCT ID: NCT05410912 Active, not recruiting - Varicose Veins Clinical Trials

Varicose Vein in Patients Under the Age of 40

Start date: January 1, 2021
Phase:
Study type: Observational

Varicose veins are a result of valvular insufficiency and presented with twisted, enlarged veins. They not only cause cosmetic concerns but also lead to limb edema, skin pigmentation/lipodermatosclerosis, and even venous ulcers. This disease affects a large percentage of the population. Although there have been several researches on the risk factors for varicose veins and the outcomes of alternative therapies , there is currently limited data focusing on varicose veins in young patients. In this case-control study, we wanted to assess the risk factors for varicose veins in patients under the age of 40, as well as their long-term results of surgery.

NCT ID: NCT05398458 Completed - Varicose Veins Clinical Trials

Management of a Giant Lymphocele Following Varicose Vein Surgery - A Case Report

Start date: January 1, 2019
Phase:
Study type: Observational

A 48-year-old female presented to the plastic surgery outpatient department (OPD) with a history of painful, progressive swelling of the right groin and medial aspect of the right thigh for 4 months. After investigation, it was diagnosed as a giant lymphocele. A pedicled gracilis muscle flap was used to reconstruct and obliterate the cavity. There was no recurrence of the swelling. : Lymphocele is a common complication after extensive vascular surgeries. In the unfortunately case of its development, prompt intervention must be done to prevent its growth and ensuing complications.

NCT ID: NCT05380895 Not yet recruiting - Varicose Veins Clinical Trials

Comparison of Daytime Surgery in Varicose Veins Patients With and Without Superficial Venous Thrombosis

Start date: June 10, 2022
Phase:
Study type: Observational

Varicose veins of lower extremities are the most common disease in vascular surgery, and daytime surgery has gradually become the mainstream of varicose veins of lower extremities. Superficial venous thrombosis is one of the common complications of varicose veins of lower limbs. Current consensus is that patients with superficial venous thrombosis should be treated with standardized anticoagulant therapy to prevent their progression to venous thrombotic disease.SVT patients need standardized anticoagulant therapy for a period of time, while DS is current mainstream treatment of VV. Will the existence of SVT affect the safety and efficacy of DS of VV, leading a need of changing the treatment strategy and carrying out anticoagulant treatment for SVT before DS on VV patients? To date, there is no research on this issue. Therefore, we conducted this study to comprehensively evaluate the safety, feasibility, perioperative and long-term efficacy of DS in VV patients complicated with SVT, and systematically compared patients who had VV only.
