Filter by:Enteral nutrition can provides prophylaxis against stress ulcer bleeding in critically ill patients and there may be no need to use acid suppressing drugs for stress ulcer bleeding prophylaxis in these patients. Half of the patients on enteral nutrition will not receive any acid suppressing drugs while other half receives it. They will be followed for gastrointestinal bleeding.
This multi-center, randomized controlled trial study is planned to include 162 outpatients with onset of acute lower gastrointestinal bleeding to compare the rate of identification of stigmata of recent hemorrhage (SRH), and other clinical outcomes, including the 30-day rebleeding rate, between 'early' colonoscopy and 'elective' colonoscopy.
The goal of this study is to identify significant clinical and laboratory risk factors in pediatric patients with significant upper gastrointestinal bleeding. This is defined as bleeding that necessitates an upper endoscopic evaluation to either diagnose or treat upper GI bleeding during their hospital admission. If a predictive/risk stratification relationship exists, these data could permit a more effective triaging and intervention scheme in pediatric patients presenting with complaints of gastrointestinal bleeding. In addition we want to get a better understanding of the re-bleeding rate after endoscopic therapy for upper GI bleeding and if there are any identifiable risk factors for re-bleeding. Lastly we want to understand best practice management for upper GI bleeding.
Endoscopic submucosal dissection(ESD) is a prominent minimally invasive operation technique for treating early gastrointestinal tumor. But promoting ESD is uneasy because of its complications such as postoperative bleeding, perforation and so on. So if we decrease the rate of postoperative bleeding, ESD might be better popularized. Some study indicated that hypertension was the independent risk factor of postoperative bleeding. Endoscopic center of Fudan University Zhongshan Hospital is a rich experienced medical unit in doing ESD operation in China. Referring to our experience, if we can use some special methods to find the potential bleeding spot which is not obvious during ESD operation and we coagulate it precisely, then we may control the risk of postoperative bleeding. Based on the above hypothesis, our team designed this study to examine whether increasing blood pressure during gastric ESD could help to control the risk of postoperative bleeding.
The primary specific aim is to perform a randomized controlled trial (RCT) to compare 30 day rebleed rates and other clinical outcomes of patients with severe, non-variceal upper GI hemorrhage (NVUGIH) - ulcers and Dieulafoy's lesions who are randomized as initial treatment with the new large over-the-scope-clip device for endoscopic hemostasis versus standard endoscopic hemostasis.
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.
Upper digestive bleeding. Upper gastrointestinal haemorrhage is a common cause of decompensated cirrhosis and is associated with a high mortality rate among cirrhotic patients. Its leading cause is the rupture of gastro-esophageal varices due to portal hypertension. In cirrhotic patients, the management of acute gastrointestinal haemorrhage is challenging as they often present with coagulation (or haemostasis abnormalities) abnormalities such as hyperfibrinolysis, especially when the cirrhosis is decompensated. Beyond life support measures, therapeutic modalities of upper gastrointestinal bleeding rely on both endoscopic and pharmacological interventions. Tranexamic acid (TA) is an antifibrinolytic that may help control the bleeding in this setting, as it showed an unquestionable benefit in other indications. TA has previously been studied in both upper gastrointestinal haemorrhage from any causes and in liver transplantation of cirrhotic patients. However, there is a lack of data to conclude on its effectiveness (or efficiency) in the early treatment of acute bleeding in cirrhotic patients. Investigators hypothesize that, when given early, TA would be beneficial for cirrhotic patients presenting with acute upper gastrointestinal haemorrhage , by controlling the haemorrhage, avoiding rebleeding episodes and reducing mortality within 5 days after its administration. Moreover, TA could prevent early cirrhosis complications (such as hepatic encephalopathy, sepsis and ascites liquid infection, hepatorenal syndrome), could reduce indications to transjugular portosystemic shunt (TIPS), shorten the length of stay in intensive care unit and the length of hospitalization, and decrease late relapses and one-year mortality.
The purpose of the study is to evaluate the safety and efficacy of Rifaximin in the treatment of cirrhotic gastroesophageal variceal bleeding.

The subject Novel Motorized Spiral Enteroscope (NMSE) represents a new technology which offers all of the advantageous options of spiral enteroscopy with a faster and less invasive approach. The system is similar to other currently marketed endoscopes in that it incorporates a flexible insertion tube, light source, digital imaging, and channels for passing accessories for sample collection or therapeutic interventions. The NMSE system is unique in that it incorporates a user-controlled motor contained in the endoscope's handle to rotate a spiral cuff located on the endoscope's insertion tube. Rotation of this cuff, which has soft spiral-shaped "fins", pleats the small bowel on to the endoscope's insertion tube, thereby allowing rapid and atraumatic access deep into the small bowel. The system also includes a display monitor, a motor control unit, device to display measured motor current and signal torque, and a set of foot pedals. Motorization of the Spiral Enteroscope and limitation of rotation to a short cuff instead of a long overtube promise to accelerate the procedure, to facilitate insertion and to improve maneuvering the instrument in comparison to conventional spiral enteroscopy
