Filter by:This study aims to characterize the diagnostic performance of immunological testing of occult gastrointestinal bleeding in stool in the population aged over 75 years with iron deficiency anemia. As secondary objectives, the study aims to: - determine a threshold of positivity optimizing the immunoassay performance for the study population, in accordance with the probabilities of error (false positives, false negatives) and weights (defined by expert consensus) allocated to these errors. - Assess the benefit of a double measure of bleeding (two stools) by immunoassay compared to a single measure.
Acute upper gastrointestinal hemorrhage (UGIH) is a common condition that leads to hospital admission, and has significant associated morbidity and mortality, especially in the elderly. The most common causes of acute UGIH are nonvariceal. Although up 70% of non-variceal bleeds settle with conservative measures, endoscopic therapy is the established method for treating those bleeds for which this is not sufficient. Despite advances and increased expertise in managing upper gastrointestinal bleeding, the associated mortality of up to 15% has remained unchanged for several years. EndoClot is a novel topical hemostatic powder approved for use in non-variceal upper gastrointestinal bleeding. This study examines its efficacy for endoscopic hemostasis in non-variceal upper gastrointestinal bleeding. This is a multicenter, prospective, randomized study.
This study compared Ulcer healing rate of Ilaprazole 20mg or Rabeprazole 20mg in the patients undergone Endoscopic Submucosal Dissection for Gastric Adenoma or Early Gastric Cancer and investigated Prevention of gastrointestinal bleeding.
Hemospray™ is a new endoscopic hemostatic powder. Aims of this multicenter prospective study is to determine effectiveness of Hemospray™ on short and medium term in different clinical situations, predictive factors of rebleeding after Hemospray™ application, and feasibility of the application of hemostatic powder in routine clinical practice studying in a large sample of patients.
Acute upper gastrointestinal bleeding is a common medical emergency. Bleeding peptic ulcers and other non-variceal causes constitute to about 95% of all cases of bleeding. Endoscopic treatment stops active bleeding, reduces rate of further bleeding and leads to improved patients outcomes. Endoscopic treatment can be technically demanding especially with lesions in difficult anatomic positions and to endoscopists with less experience. TC-325 is a propriety mineral blend hemostatic powder used to compress external civilian and military traumatic injuries. Investigators reported the first endoscopic application of TC-325 in 20 patients with actively bleeding gastro-duodenal ulcers. Investigators were able to stop bleeding in 19 of them. Subsequent case series from others reported a similar rate in the acute control of bleeding. To further define the role of TC-325 as a mono-therapy, a comparison to the current standard in endoscopic treatment is required. A non-inferiority randomized trial is being proposed to compare endoscopic use of TC-325 as a mono-therapy to current standards (i.e. hemoclips or thermo-coagulation with or without pre-injection with diluted epinephrine) in hemostatic treatment in patients with acute upper gastrointestinal bleeding from non-variceal causes. The non-inferiority primary endpoint is control of bleeding over 30 days from randomization. Other outcome endpoints include further endoscopic, angiographic or surgical treatments, hospitalization, blood transfusion and mortality. Investigators also compare ease of therapy measured by procedure time and a 10 cm visual analogue scale rated by endoscopists. Endoscopic application of TC-325 is a simple and less skill dependent technique. It may prove useful in bleeding from anatomically challenging sites of the gastro-duodenal tract.
This is a prospective and observational study to evaluate oncologic patients that presented upper gastrointestinal bleeding with the use of some prognostic scores.
Stress ulcer prophylaxis (SUP) is standard of care in the intensive care unit (ICU), however the quantity and quality of evidence is low and potential harm has been reported. The aim of the SUP-ICU trial is to asses the overall benefits and harms of SUP with proton pump inhibitor in adult critically ill patients in the ICU.
Video capsule endoscopy is an important procedure that can be used by doctors to find abnormalities in the small intestine, especially those that can cause bleeding. The procedure uses a tiny wireless camera to take pictures of the digestive tract. The camera sits inside a vitamin-sized capsule that a person can swallow. As the capsule travels through the digestive tract, the camera takes thousands of pictures that are transmitted to a recorder worn on a belt around a person's waist or over his/her shoulder. However, abnormalities can be missed partly because the normal dark liquids present in the intestine can prevent abnormalities from being recorded, hiding them from the physician who reviews the video. The current method used to clear these dark liquids from your small intestine is to follow a clear liquid diet and drink approximately 2 quarts of polyethylene glycol (Golytely®) the day before the video endoscopy and take simethicone (a medication used to treat symptoms of gas such as uncomfortable or painful pressure, fullness, and bloating) the morning of the test. Some of the current preparations to clear these dark liquids are not able to entirely prevent abnormalities from being missed and most have an unpleasant taste or involve drinking a lot of fluid. Linaclotide (Linzess®) is a medication approved by the Food and Drug Administration (FDA) for the treatment of constipation and irritable bowel syndrome. It is not approved by the FDA for use as an aid for clearing dark liquid from the small intestine prior to a video endoscopy. A recent presentation at a medical meeting proposed using one-dose of linaclotide (Linzess®) to improve cleansing of the small intestine for capsule endoscopy preparation to supplement fasting and clear liquid diet. This report claimed a noticeably better quality of small intestine cleansing and a 20% shorter transit time for the capsule by taking one dose of linaclotide one hour before patients swallowed the video capsule. The purpose of this study is to assess the use of one dose of linaclotide in terms of the total time it takes the capsule to move through the small bowel, and image quality as compared to the current method. The results of this study will be compared to previous patients who drank the preparation that is currently used
Background - Patients presented to hospital with coffee ground vomiting and black stool may not be actually having upper gastrointestinal bleeding (UGIB) - Hospital admission can be avoided if serious UGIB can be excluded - To date, the only useful tool to triage patient for hospital admission in UGIB is by using clinical score such as Rockall score or Blatchford score - These scores are cumbersome and only exclude the most benign cases, but they are not useful in differentiating those who needs intervention - In our pilot study, investigators found that capsule endoscopy can be used to identify patients with fresh blood and real coffee ground substance in the stomach and it is superior to nasogastric tube - Most of UGI lesions leading to bleeding can be diagnosed by capsule endoscopy Objectives The current study is designed 1. to validate capsule endoscopy is an effective method in identifying patients with UGIB 2. to study whether the capsule endoscopy can reduce requirement of hospital admission in patients with suspected UGIB 3. to study if capsule endoscopy can help to identify patients with UGIB that may require urgent (within 24 hours) endoscopy and intervention 4. to study the cost-effectiveness of capsule endoscopy being used as a triaging tool in the management of UGIB 5. to compare the effectiveness of capsule endoscopy against Blatchford score in identifying patients with UGIB that may require endoscopic intervention.
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.
