Filter by:The aim of this retrospective study is to investigate the relationship between factor XIII activity and the outcome of gastrointestinal bleedings. Since factor XIII is of great importance in haemostasis and plays a key role in stabilizing the fibrin clot, it can be assumed that a deficiency of factor XIII leads to an unfavorable course of gastrointestinal bleedings. Our hypothesis is that early detection of such a deficiency can prevent a more severe course and that substitution of factor XIII contributes to faster cessation of bleeding, improves patient outcome and reduces the number of red cell concentrates required.
Bleeding from the gastrointestinal tract can originate from the small bowel. Typically, upper and lower endoscopies are unable to identify the site of bleeding and patients need to undergo special endoscopies with longer cameras to examine the small bowel and find the bleeding site. One of the most commonly used scopes to investigate the first part of the small intestinal is called "push enteroscopy". This is an upper endoscopy that uses a pediatric colonoscope, which is longer. To date, it is unknown what percentage of small bowel can be observed with this technique. Hence, this study aimed to determine the extent of small bowel examined by push enteroscopy. Consecutive patients with suspected bleeding from the small intestine will undergo a push enteroscopy and the depth of the examination will be marked with metallic clips. Subsequently, patients will have a capsule endoscopy, which is a little camera that will take multiple pictures of the whole small intestine. The percentage of small bowel that the push enteroscopy examined will be determined by the percentage of small bowel corresponding to the location of the clips visualized on capsule endoscopy.
The RE-BLEED feasibility study aims to develop and test a real-time digital platform, whereby bleeding patients in-hospital can be identified and approached for their consent to participate in future research studies.
Hp infection is closely related to upper gastrointestinal bleeding in patients who need dual-antiplatelet after PCI. Taking anti-Hp treatment has the effect of reducing bleeding risk. Thus, we propose a scientific hypothesis: the C13 breath test may be used to assess the risk of upper gastrointestinal bleeding in patients who need dual- antiplatelet after PCI.
Title: The efficacy of hemostatic powder TC-325 versus standard endoscopic treatment for gastrointestinal bleeding from malignancy; a multi-center randomized trial Background: Gastrointestinal (GI) bleeding arising from malignant tumors is increasingly recognized as a result of oncological advances and improved detection methods. However, conventional endoscopic hemostatic methods are not reliable to control bleeding. It has a trend to be an effective hemostasis method for active GI bleeding from tumor, however, in view of the lack of RCTs and large-scale studies, the efficacy of TC-325 is still inconclusive. Objective: To evaluate the efficacy of TC325 in endoscopic hemostasis treatment for malignant gastrointestinal hemorrhage.The 24-hour, 72-hour, 30-day, 90-day and 180-day rebleeding rate were assessed as the outcomes of treatment as well as 6-month mortality. Study design: Single-blinded, multi-center, randomized-control trial study The intervention (experimental) arm: TC-325 alone (define failure if continued bleeding despite application of 1 syringes) The control arm: Standard of (traditional) endoscopic treatments ** Crossover is possible. Inclusion criteria: Patients with acute upper or lower GIB from a lesion that is actively bleeding at index endoscopy (spurting or oozing) and is suspected to be malignant or diagnosed as malignancy from previous tissue diagnosis. Exclusion criteria: Patients less than 18 years old, previously included in the trial, ECOG score 3 or 4, pregnancy/lactation, and/or bleeding from GI sources suspected of not being malignant. If an endoscopist is unsure of the malignant likelihood of the lesion, he/she will not be enrolled. Sample size: 112 in total Duration of participation for each volunteer: 180 days
This phase II trial studies how well isatuximab works in treating patients with primary amyloidosis that has come back or does not respond to treatment. Monoclonal antibodies, such as isatuximab, may interfere with the ability of cancer cells to grow and spread.
Endoscopic Injection Sclerotherapy vs N-butyl-2-cyanoacrylate Injection
The purpose of this study is to determine whether long-acting octreotide is safe and effective in the treatment of patients with Rendu-Osler-Weber (e.g. HHT). The study hypothesis is that octreotide is safe and will reduce transfusion requirements and endoscopy frequency in ROW patients with refractory anaemia due to bleeding gastrointestinal telangiectasias.
Unlike the management of patients with various forms of accidents (e.g. polytrauma), only a few data exists for the emergency management of patients with acute gastrointestinal bleeding. The aim of our study is to develop optimal diagnostic and therapeutic algorithms for the management of acute upper and lower gastrointestinal bleedings.
The researchers will investigate whether erythromycin infusion is better than gastric lavage prior to emergency endoscopy to improve the quality of examination in patients with upper gastrointestinal bleeding.
