Active clinical trials for "Gastrointestinal Hemorrhage"

To evaluate the incidence and etiology of small bowel or large bowel bleeding in patients presenting with melena.

A bleeding peptic ulcer remains a serious medical problem with significant morbidity and mortality. Endoscopic therapy significantly reduces further bleeding, surgery, and mortality in patients with bleeding peptic ulcers and is now recommended as the first hemostatic modality for these patients. In the past few years, adjuvant use of a high-dose proton pump inhibitor (PPI) after endoscopic therapy has been endorsed in some studies. However, low dose of PPI has also been supported in the management of these patients. The investigators enroll 130 patients with active bleeding or nonbleeding visible vessels in this study. They are randomly assigned as 40 mg/day or 160mg/day IV nexium group. All patients receive successful endoscopic therapy with heater probe or hemoclip placement. In the low dose group (N=65), 40 mg IV Nexium daily is given for three days. Thereafter, the patients receive 40 mg nexium orally daily for two months. In the large dose group (N=65), 160 mg/day continuous infusion is given for three days. Thereafter, the patients receive 40 mg nexium orally daily for two months. The primary end point is recurrent bleeding before discharge and within 14 days. At day 14, volume of blood transfused, number of surgeries performed, and the mortality rates of the two groups are compared as well.

Primary objective: Evaluation of capsule endoscopy in the emergency setting of severe GI-Bleeding.

In this study, we aimed to investigate the effectiveness of ppi use in upper gastrointestinal bleeding in patients over the age of 18 who underwent endoscopy on mortality, length of hospital stay, rebleeding, and cost. The European Society of Gastrointestinal Endoscopy 2021 recommends the use of preendoscopic ppi in patients with nonvariceal upper gastrointestinal bleeding as it reduces the need for endoscopic treatment. This recommendation is recommended by the British Institute for Health and Care Excellence not to use proton pump inhibitors. Likewise, the 2021 American Gastroenterology Association did not make a recommendation for its use because the benefit of using preendoscopic ppi is uncertain. This has led to confusion about the efficacy of ppi and has questioned the necessity of routinely given high-dose ppi therapy. In this study, we aim to reveal the effectiveness of the treatment by comparing the patients who were given and not given ppi. Our research is a retrospective cohort study. Patients over the age of 18 who applied to the emergency department and had a preliminary diagnosis of upper gastrointestinal bleeding and underwent endoscopy will be included in the study. Patients who underwent endoscopy and were given ppi and those who were not will be compared. In upper gastrointestinal bleeding, patients with a Glasgow Blatchford score of 2 and above are taken to endoscopy. Therefore, patients over the age of 18 who underwent endoscopy will be included in the study.

This study is to determine the feasibility and safety of magnetic-controlled capsule endoscopy system in examination of human colon under the real time monitoring by colonoscopy in the clinical application.

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 is an observational, retrospective, analytical, and multicenter study conducted at 17 hospitals. Our research aims to assess the effectiveness of Hemospray® in patients with gastrointestinal bleeding in clinical practice. Besides, we aim to detect predictors of treatment failure defined as unsuccessful immediate hemostasis or rebleeding.

Problem statement GI bleeding can arise from peptic ulcers, malignancy, angiodysplasia or during endoscopic resection procedures such as endoscopic mucosal resection and endoscopic submucosal dissection. This is conventionally treated using heat therapy or clips. These methods carry a risk of thermal injury or perforation. Purastat® is a novel synthetic haemostatic agent licensed as a CE marked device for use in GI bleeding. It also has the potential to enhance endoscopic mucosal wound healing and may play a role in preventing delayed bleeding. However, clinical data on its effectiveness in the GI tract is limited. Prospective data collection on the range of indications for Purastat® use and outcome data related to clinical effectiveness, safety and feasibility is required to inform clinicians about the best use for this agent. Research question / hypothesis To establish a prospective registry study to collect outcome data related to the use of Purastat® for the clinical management of GI bleeding or prevention of bleeding Study Design Prospective multicentre cohort study Study Participants Adults with GI bleeding or a high risk of bleeding during endoscopic procedures where Purastat® has been used Follow-up duration All patients will be followed up as per standard clinical care where applicable Planned Study Period 2 years Primary Objective To assess the effectiveness of Purastat® as a haemostatic agent when used in the treatment of GI bleeding Secondary Objectives To assess the incidence of delayed bleeding after use of Purastat®, defined as procedure related bleeding up to 28 days following endoscopic resection To evaluate the rate of rebleeding following primary application of Purastat® for haemostasis To assess the technical feasibility and ease of use of Purastat® when used in the treatment or prevention of GI bleeding To monitor any unexpected reactions that may be attributed to the use of Purastat® To describe utilisation patterns in different clinical centres (indication, patient characteristics etc) and to observe trends in utilisation over time

Lower gastrointestinal bleeding occurs distal to the ligament of treitz and may involve the small bowel, colon and rectum . Active lower gastrointestinal bleeding is a common, potentially life threatening medical presentation that can be challenging to localize and treat . There are many diseases that may cause lower gastrointestinal bleeding, including angiodysplasia, diverticulosis, benign or malignant bowel neoplasm, inflammatory bowel disease, ischemic bowel disease, and infectious bowel disease. Often, gastrointestinal bleeding will stop spontaneously, but in approximately 25% of patients, bleeding is massive or recurrent, requiring imaging localization and directed therapy.

Acute nonvariceal upper gastrointestinal bleeding (ANVUGIB) is a common critical disease in gastroenterology. Due to the development of modern medical technology, the incidence rate of ANVUGIB has been decreasing in recent years, but its mortality within 30 days is still 11%. Endoscopic hemostasis and drug therapy are the first choice for the treatment of ANVUGIB. After endoscopic hemostasis, it is very important to treat peptic ulcer bleeding with strong acid suppression therapy to maintain gastric pH above 6.0. This study is to study the effect of endoscopic and drug treatment of ANVUGIB.
