Filter by:MCE first algorithm is not inferior to standard of care algorithm in terms of further bleeding in hemodynamically stable patients with acute overt and non-hematochezia GI bleeding.
This study will evaluate the use of the Olympus EndoCapsule EC-10 video capsule compared with the standard of care workup for patients in the Clinical Decision Unit who have symptoms of gastrointestinal (GI) bleeding. Patients will be eligible if they have any symptoms of GI bleeding, either vomiting blood or symptoms without vomiting blood. Patients randomized to the early capsule arm will have an immediate video capsule endoscopy. Patients randomized to the standard of care arm will have no study intervention and will follow the treating physician's diagnostic workup. The primary goal of the study is to compare how often a source of bleeding is identified in patients in the two groups.
Acute upper gastrointestinal bleeding (AUGIB) is a common medical emergency. In an ageing population, antiplatelet drugs are increasingly being prescribed for treatment and prophylaxis against cardiovascular thrombo-embolic events. In many patients, platelet dysfunction mostly acquired is the principal cause of bleeding. To clinicians, the management of patients on antiplatelet drugs or anticoagulants is a challenge. One has to carefully balance the bleeding against thrombo-embolic risks. Therefore measuring platelet function should be integral in the management plan. A quantitative measurement allows titration of platelet function in accordance with bleeding or thromboembolic risk. Platelet function has not been studied in a large cohort of patients with acute upper gastrointestinal bleeding. As a first step, the study will determine if platelet dysfunction is associated with clinical outcome. In this prospective, observational single centre cohort study of consecutive patients with overt signs of acute upper gastrointestinal bleeding, their platelet function by point of care tests (light transmittance aggregometry, verify now p2y12,the platelet function analysis system (PFA-100) upon their admissions. Patients will be followed up for 30 days after trial enrollment. The primary endpoint is defined as significant bleeding that requires interventions (endoscopic, radiologic or surgery). Secondary end points include cardio- and cerebrovascular thrombo-embolic events and all cause deaths. A receiver operating characteristic (ROC) curve analysis is calculated for each point-of-care test to evaluate if individual test can distinguish between patients with and without primary end point. This study aims to evaluate the capability of platelet function tests to predict clinical outcome in patients with AUGIB. Logistic regression models will then be built in search for independent correlates to the primary and secondary endpoints and to adjust for confounding variables.
The objectives of this study are to test whether there are statistically significant differences between the standard of care workup workup of non-hematemesis gastrointestinal bleeding by endoscopy [upper, lower and other tests], compared with deployment of a video capsule as the first test followed by the most appropriate endoscopic procedure based on video capsule findings, if needed. The investigators propose to examine differences in time to diagnosis, reduction in numbers of procedures, and length of stay between a standard of care workup protocol and our proposed protocol of early capsule endoscopy deployment.
The incidence risk of colorectal cancer （CRC） is increasing at 4.2% year by year in China. Most effective way to reduce the death rate of CRC patients is to diagnose in quite an early stage. QiaoKou District is a chemical industry Zone of Wuhan with a long history, which has few data of CRC epidemiology. The investigators design the primary CRC screening for this district by healthy questionnaire, Fecal Occult Blood Test(FOBT) and colonoscopy. HanYang Areo has been chosen as Control for its non-industry environment.The crowd would be screen biennially. The high risk group would be intervened, such as resection of polyps or other specific treatment. A follow-up registration database has been built for analysis the relationship between incidence or death rate to high risk factors, such as age, life environment, lifestyles, base diseases and family history of cancer. This study will provide some epidemiology dates of CRC to the local Government, and assist the governor to built a more effective screening system of CRC.
Comparative, randomized study patients are scheduled to have two capsule endoscopies within 2 to 14 days from each other using two different endoscopies the Pillcam SB2 (Given Imaging, Israel) and the Capsocam (Capso Vision Saratoga United States) The order in which the devices are administered is randomly allocated.
The researcher's primary hypothesis is that VCE allows for safe outpatient management of ED patients with suspected upper GI hemorrhage. A prospective multicenter randomized control trial was designed to investigate the safety of this approach.
Terlipressin and Octreotide are two common agents used as adjuvants in the management of variceal bleeding. Both agents have been claimed equivalent to endoscopic therapy in randomized studies. There are no head to head clinical trials of these two agents available in the literature. We aimed to compare the efficacy and safety of Terlipressin and Octreotide in combination with Endoscopic Variceal band Ligation (EVL)in patients presenting with Esophageal Variceal Bleed (EVB).
The purpose of this study is to determine whether Thalidomide is effective in the treatment of arteriovenous malformations in the gastrointestinal tract.
