Filter by:Conventional supplemental oxygen therapy (COT) during upper gastrointestinal (UGI) endoscopy via nasal catheter is considered the standard practice in maintenance of oxygenation and prevention of hypoxia. However, it is still unclear if this oxygen delivery method is optimal in a prolonged (more than 15 minutes) procedure in patients admitted to the ICU. Because of shortage of data in this concern, this prospective, randomized, controlled clinical trial study will aim to evaluate and compare the efficacy of high-flow nasal cannula (HFNC) oxygen therapy versus COT in patients who will undergo prolonged either diagnostic or therapeutic UGI endoscopy in the intensive care unit (ICU) .
A prospective, randomized, double-blind study will be conducted, including all patients with upper gastrointestinal bleeding, defined as vomiting blood or black bowel movements, within 12 hours prior to admission. Patients will be randomized to receive intravenous metoclopramide 20 mg or placebo, a placebo is a look-alike substance that contains no active drug. Then endoscopy will be performed in the following 120 minutes, evaluating endoscopic visualization with the modified Avgerinos scale.
The purpose of this pilot clinical trial is to confirm the efficacy and safety of Nexpowder™ for hemostasis in pilot cohort of patients with NVUGIB in Singapore
The Comprehensive HHT Outcomes Registry of the United States (CHORUS) is an observational registry of patients diagnosed with Hereditary Hemorrhagic Telangiectasia (HHT). The purpose of this study is to better understand HHT, the symptoms and complications it causes, and the impact the disease has on people's lives. The investigators will collect long-term information about the participant, allowing us to understand how the disease changes over time, and what factors can influence those changes. Ultimately, this should help improve treatments for the disease. Another important goal of the study is to provide a way to contact people to participate in future clinical trials and other research. The registry will be a centralized resource for recruitment for clinical trials. People in the registry will not be obligated to join any of these additional studies, but if interested, can agree to be contacted if they may be eligible for a study. Participants will: - Be asked to provide permission to collect information from their medical records, including things like demographic information, diagnosis information, family history, test results, treatment information, symptoms, complications, lifestyle and other relevant medical information. - Be asked study-related questions by phone or at a clinic visit. - Be asked study-related questions every year after enrollment for up to 10 years or until the study ends. A member of the study team will communicate with participants by phone or at clinic visits to collect information regarding any changes to their health over the previous year/s including new test results, treatment information, symptoms, and complications from HHT.
The main goal of this study is to assess whether the diagnostic efficacy of enema is non-inferior to that of oral polyethylene glycol (PEG) in acute lower gastrointestinal bleeding (ALGIB) patients requiring urgent colonoscopy. The secondary objectives include: 1) evaluating potential differences between the enema and oral PEG groups in terms of the difficulty and safety of colonoscopy, as well as exacerbation of bleeding; 2) conducting subgroup analyses to compare the effectiveness of the two bowel preparation methods in specific populations, exploring potential candidate groups for different bowel preparation strategies, and promoting individualized diagnosis and treatment for ALGIB.
Controlled-randomized trial evaluating single-use versus reusable gastroscopes in patients with upper gastrointestinal bleeding.
This study aim to evaluate the efficacy of metoclopramide for gastric visualization in patients with active UGIB. This is a double-blinded, multicenter RCT. Patients with 'active' UGIB (hematemesis or presence of fresh blood in the nasogastric tube) were enrolled. The eligible patients were randomly assigned in a concealed 1:1 allocation to received either intravenous metoclopramide or placebo before endoscopy. The primary outcome was 'adequate visualization' by objective endoscopic visualized scores(EVS). Secondary outcomes included mean difference in total EVS and EVS at each location , duration of EGD, immediate hemostasis, need for a second look EGD, units of blood transfusion, length of hospital stay and 30-day rebleeding rate.
Safety and effectiveness of a new hemostatic system to prevent delayed bleeding after endoscopic resection in a selected high-risk population (NEXPOWDER- ENDOHS). Indication: Patients with indication of endoscopy resection by endoscopic mucal resection (EMR) or endoscopic submucosal dissection (ESD) with high risk of delayed bleeding (≥5%). Hypotheses: The use of NexpowderTM after upper and lower gastrointestinal ESD or EMR of ≥20mm in high-risk population will prevent and decrease delayed bleeding to less than 5%.
Prospective observational pilot study evaluating the frequency of cow's milk protein allergic prococolitis in newborns hospitalized in neontal medicine at the university hospital of Nice who presented rectal bleeding.
This study will test the hypothesis that azythromycin is efficient and safe in cleansing the upper gastrointestinal tract for endoscopic examination in the case of acute bleeding.
