Filter by:The investigators previously showed that the use of a high-dose intravenous PPI regimen after endoscopic control of bleeding from peptic ulcers reduced rate of recurrent bleeding, decreased the need for endoscopic and surgical interventions and in general improved patients' outcomes. A trend towards reduced mortality associated with the use of high-dose intravenous PPI was also observed. Recent clinical trials from Asia have provided evidence that high-dose oral PPIs are associated with a reduction in rebleeding. Current meta-analysis suggests that both high dose (intravenous) and low dose (oral) PPIs effectively reduce rebleeding vs placebo. However, there has been no clinical study to compare IV infusion to oral PPI in this patient population. The purpose of this clinical study is to compare the efficacy and safety of intravenous and oral Esomeprazole in patients with peptic ulcer hemorrhage who are at risk for recurrent bleeding. The investigators hypothesize that using IV infusion is superior to oral PPI.
The aim of this study is to determine if early angiographic embolization can forestall recurrent bleeding in selected high risk ulcers after their initial endoscopic control; to validate prospectively the investigators proposed in selecting high risk ulcers for recurrent bleeding in spite of maximal endoscopic control and profound acid suppression using high dose intravenous infusion of proton pump inhibitor; to characterize the nature of bleeding arteries in severely bleeding peptic ulcers and determine the efficacy of angiographic embolization in the prevention of recurrent bleeding and to establish safety profile of angiographic embolization as an early elective treatment to bleeding peptic ulcers.
The purpose of this study is to determine tranexamic acid plasma levels in children undergoing cardiac surgery at risk of bleeding and to compare two dosing regimens.
Previous studies showed that combination of endoscopic therapy with vasoconstrictor is better than either vasoconstrictor or endoscopic therapy alone in achieving the successful hemostatsis of acute variceal bleeding. The rationale of using vasoconstrictor is to enhance the efficacy of hemostasis by endoscopic therapy. Nowadays, endoscopic variceal ligation (EVL) has replaced endoscopic injection sclerotherapy (EIS) as the endoscopic treatment of choice in the arresting of acute esophageal variceal hemorrhage. EVL alone can achieve hemotasis up to 97% even in cases of active variceal hemorrhage. However, early rebleeding due to ligation-induced ulcer may be encountered. It appears that prevention of esophageal ulcers and bleeding by a proton pump inhibitor may be more logical than using a vasoconstrictor after cessation of bleeding by EVL.
The aim of the study is to observe the effects of antihemostatic therapy including nonsteroidal antiinflammatory, anticoagulant and antiaggregant therapy and other patient and procedure related factors on the risk of endoscopic biliary sphincterotomy induced bleeding.
The first magnetic resonance-guided focused ultrasound (MRgFUS) treatment of uterine fibroid using the ExAblate 2000 system was performed in 2001. Since then, more than 5000 treatments were done in more than 60 different hospitals around the world. The experience accumulated in this novel treatment was collected by InSightec and implemented into software and hardware updates, clinical tips and guidelines, all aimed to improve the clinical results and their durability, while maintaining a high level of safety. Based on extensive clinical experience and our internal research and development effort goals toward continuous improvement in ExAblate treatment safety and performance, limited changes have been made to the current ExAblate system. This modified ExAblate system version is designated as the ExAblate 2100 UF V2 system. The modifications are believed to improve system's friendliness to the user, without introducing new risks or other issues of safety of the device, and should not have any negative impact on the safety or technical efficacy of the treatments for patients.
MiroCam® is the new video capsule endoscope of IntroMedic®. By using a novel transmission technology it promises a longer battery life expectancy with consequential impact on the length of the video recorded for diagnostic evaluation. As the investigators know about the shortcoming of battery life expectancy from many capsule examinations that were inconclusive because the ileocaecal transit was not filmed, the investigators would appreciate to have a capsule with extended video recording to improve the diagnostic yield of capsule examinations. Therefore the investigators want to compare MiroCam® to our routinely used Olympus® Enteropro EndoCapsule® in the context of a half-year clinical trial. Focussing on the total video length as well as on the rate of video-recorded ileocaecal transitions as surrogate parameters the investigators want to find out whether one of the two products provides superior diagnostic information in order to reduce the amount of inconclusive examinations.
1. Balloon-assisted enteroscopy (BAE) is a new tool to investigate small intestinal diseases. 2. Deep enteroscopy made possible by balloon expansion and manipulation of small intestines. 3. However, whether intestinal barrier injured during BAE predispose patients to bacteremia or clinical relevant infection is not studied. 4. We will also examine relevant patient factors.
Haemorrhoidal artery ligation operation (HALO) is an operation that ties off vessels to piles. This study examines whether the ultrasound (doppler) is necessary to guide this tying off or not.
ASPREE-XT is a post-treatment, longitudinal observational follow-up study of ASPREE participants [ASPREE Investigator Group, 2013; www.aspree.org; McNeil et al 2017]. Although the ASPREE trial medication was ceased, the study activity was not stopped and ASPREE participants are continuing with scheduled visits and phone calls. An observational follow-up phase (ASPREE-XT), began in January, 2018. This will enable the monitoring of possible delayed effects of aspirin treatment, primarily on cancer incidence, metastases and mortality. In addition to monitoring the incidence of malignancy within the ASPREE cohort, the opportunity will be taken to observe any other residual effects of aspirin on the endpoints being monitored in the cohort. Continuity of contact with study participants is the key to retention of the cohort for any ongoing or future studies.
