Researchers will compare use rabeprazole alone as routine therapy to see if Yiwei JiaoHuang Ointment can accelerate the conversion to negative results in fecal occult blood tests. Participants will ： Take Yiwei JiaoHuang Ointment every day for 2 weeks. Return to the hospital for a fecal occult blood test after 3 days, 1 week, and 2 weeks of medication.

Management of Gastrointestinal Bleeding Under Direct Oral Anticoagulants

Gastrointestinal bleeding (GIB) is a common emergency in hepatology and gastroenterology, with an overall mortality rate ranging from 5% to 10% depending on the study. GIB is classified into two categories: upper GIB (80% of cases) and lower GIB (20% of cases). There are many risk factors for GIB, including anticoagulants. In cases of GD under anticoagulants, there are specific management recommendations. In particular, in cases of severe bleeding under direct oral anticoagulants (DOACs), it is recommended to stop treatment and correct coagulation parameters according to the severity of the bleeding and the associated thrombotic risk. Various treatments can be used for this purpose, including specific antidotes, fresh frozen plasma, and prothrombin complex concentrate (PCC). However, the role of PCC in this indication is uncertain, as is the efficacy and safety data for this drug, due to significant methodological limitations in the few studies conducted on the subject.

How Often Does the Fecal Test for Occult Blood Turn Positive After Using Blood Thinners?

Blood thinner medications used for cardiovascular disease can cause gastrointestinal bleeding. Early detection of invisible bleeding by performing occult fecal blood test (called fecal immunochemical test, or FIT) can uncover serious disease in the stomach and intestine and enable the treating physician to refer the patient for further evaluation.

Pediatric GI Endoscopy at Assiut University

1. To evaluate the diagnostic role, and outcomes of upper and lower gastrointestinal (GI) endoscopy in identifying gastrointestinal disorders among infants and pediatric patients attending Assiut University Children Hospital. 2. To determine which pediatric patients require endoscopy as part of the diagnostic process. 3. To assess the safety and effectiveness of endoscopic procedures in the detection and management of various gastrointestinal disorders among pediatric patients at Assiut University Children Hospital.

A Study to Evaluate the Performance of a Wireless Optical Sensor Capsule in Detection of UGIB

Upper gastrointestinal bleeding (UGIB) is a common and potentially lethal medical emergency, which requires hospitalization and healthcare resources. Despite the changing epidemiology and advancement of endoscopic therapy in the recent decade, the all-cause mortality of UGIB remains high (\>2%). An accurate risk stratification is necessary to triage patients into low- or high-risk groups, in order to inform clinicians for the necessity and timing of urgent endoscopy. However, existing pre-endoscopy risk scores, such as the Glasgow-Blatchford score (GBS), Rockall score and AIMS65 score, are suboptimal in predicting relevant clinical outcomes. An alternative strategy for risk stratification is urgently warranted in patients with UGIB to guide the next step of management. In a pre-clinical study, the sensitivity and specificity of HemoPill® prototype were 95% and 87.5% respectively, when the sensors were positioned close to the bleeding point. Furthermore, several human clinical studies have proven the feasibility and accuracy of HemoPill® in healthy volunteers and patients with suspected UGIB. Capsule ingestion was well tolerated with no device-related adverse event or capsule retention. All patients with negative HI were found to have no active endoscopic bleeding (true negative, 100%, 17/17). In patients with bleeding \>20ml, true positive HI signals were detected (100%, 2/2) In a retrospective multi-center study, 61 patients with suspected UGIB were recruited to use HemoPill®. Among the capsule-positive cases, subsequent endoscopy confirmed active bleeding in 57% (20/35) of them. None of the capsule-negative patients rebled (0%, 0/25), which prevented unnecessary emergent endoscopy in 72% of them (18/25).

MCE Identifying Bleeding Lesions in Patients with Antiplatelet Drugs-Related Acute Non-Hematochezia Gastrointestinal Bleeding

The goal of this clinical trial is to explore the diagnostic efficacy of detachable string magnetically controlled capsule endoscopy (ds-MCE) for identification of bleeding lesions in patients with antiplatelet drugs-related acute non-hematochezia gastrointestinal bleeding. The main questions it aims to answer are: Compared to the conventional esophagogastroduodenoscopy, does ds-MCE accurately detect bleeding lesions in the upper gastrointestinal tract in patients with antiplatelet drugs-related acute non-hematochezia gastrointestinal bleeding? Recording bleeding lesions in the small bowel detected by ds-MCE in patients with antiplatelet drugs-related acute non-hematochezia gastrointestinal bleeding. Participants will: Undergo ds-MCE first and subsequently EGD within 24 hours. Receive follow-up in the following 30days.

Australian and New Zealand Massive Transfusion Registry

Severe and un-stopped blood loss can occur for a number of different reasons including after a serious injury, delivery of a baby and following other medical and surgical emergencies. The investigators understanding of how to best treat people with serious bleeding is still incomplete, with many questions remaining. These include questions regarding how many people have serious bleeding events, what happens to them and the best way to treat them. The Massive Transfusion Registry (MTR) is a register of patients who have experienced major blood loss that required a massive transfusion in any clinical setting. The MTR uses electronic data extraction and data linkage methodologies. Pre-existing clinical data from hospital data sources, including Laboratory Information Systems (for transfusion history and laboratory results) and Health Information Services databases (for Patient demographics and admission data), are electronically extracted by staff employed at the participating hospitals. The data is then sent to the MTR Research Team, located at Monash University, where it is then linked, analysed and stored. The establishment of a Massive Transfusion Registry will be a unique and important resource for clinicians in Australia, New Zealand and internationally, for Blood Services and for the broader community. It will provide valuable observational data regarding the types and frequency of conditions associated with critical bleeding requiring massive transfusion, the use of blood component therapy (i.e. ratios and quantities of different types of red cell to non- red cell components) and patient outcomes.
