Filter by:The purpose of this study is to determine whether a long-term prophylactic use of esomeprazole 20 mg twice daily or once daily has prevention effectiveness in reducing the recurrence of peptic ulcer bleeding after ulcer healed with 16-week oral esomeprazole therapy in high-risk patients whose Rockall score ≥ 6.
The present study is a randomized controlled trial (RCT) that examines if the outcome of peptic ulcer bleeding could be improved by use of doppler-guided endoscopic treatment.
Bleeding peptic ulcer is a common medical emergency. Endoscopic treatment stops bleeding in those actively bleeding from their peptic ulcers, reduces further bleeding, transfusion, surgery and deaths. After initial endoscopic control of bleeding, approximately 10% of them will develop recurrent bleeding. Mortality rate in this group of patients is at least 4 fold higher. In the few who need surgery, mortality approaches 30%. Prevention of further bleeding is therefore a major treatment objective. Currently the investigators use a high dose infusion of proton pump inhibitor (PPI) for 72 hours to render gastric pH neutral. In a previous randomized trial, the investigators showed that the rate of bleeding in 30 days was around 7% with such an approach. In a small subgroup of high risk patients defined by presentation with shock and ulcers > 2 cm in size, 1 in 6 would re-bleed. An alternate strategy is to select those at especially high risk of further bleeding and repeat endoscopic treatment the next morning. The investigators have shown that persistence of major bleeding stigmata, i.e. a visible vessel, during a second endoscopy predicts further bleeding. It is therefore logical that by repeating endoscopic treatment the next morning, the investigators can prevent further bleeding and possibly surgery and deaths. The current study proposes to develop a score to identify those at risk of further bleeding after endoscopy. The investigators used a historical cohort with carefully collected clinical data to derive a risk score. In this derivation phase of 939 patients, the investigators have developed a 9 point risk score which consists of the following parameters (Age>60, Male sex, ulcer>2cm, posterior bulbar in location, spurting or Forrest Ia bleeding and admission hemoglobin of < 8 g/dl). Using AUROC and Youden J statistics, a score of 5 or above has been shown to highly predictive of further bleeding. The score will then be validated in a prospective cohort of patients with bleeding peptic ulcers. In the final phase of this study, the investigators propose a randomized controlled trial to test the hypothesis that a second look endoscopy with treatment in selected high risk patients can further reduce bleeding and improve their outcomes. After endoscopic hemostasis to their bleeding peptic ulcers, patients are risk stratified based on the score. Those with a score of 5 or more are randomized to receive the standard treatment (a high dose PPI infusion) or a second look endoscopy with treatment in addition to PPI infusion. The primary outcome to the trial is further significant clinical bleeding.
This study aimed to validate CU prediction model on mortality for patients with high risk bleeding peptic ulcers after therapeutic endoscopy.
Background: A second endoscopic method added to injection therapy is recommended for high-risk bleeding peptic ulcers. Many endoscopic devices have been proved as useful hemostatic instruments, whereas the hemostatic efficacy of argon plasma coagulation (APC) has not been widely investigated. Aim: This study was designed to know whether additional APC treatment could influence the hemostatic efficacy after endoscopic injection therapy in treating high-risk bleeding ulcers. Methods: From October 2010 to January 2012, eligible patients who had high-risk bleeding ulcers were admitted to our hospital. They prospectively randomly underwent either APC therapy plus distilled water injection or distilled water injection alone. Pantoprazole infusion was conducted during the fasting period after endoscopy and orally for 8 weeks to encourage ulcer healing. Episodes of rebleeding were retreated with endoscopic combination therapy. Patients who did not benefit from retreatment underwent emergency surgery or transarterial embolization (TAE).
The purpose of this prospective study is to identify risk factors which could predict poor fading of SRH or early recurrent bleeding of peptic ulcer hemorrhage after successful endoscopic hemostasis and high-dose PPI infusion. These risk factors will be the selection criteria for patients who are indicated to receive second-look endoscopy.
The purpose of the investigators study is to investigate the factors associated with rebleeding in patients with peptic ulcer bleeding.
Hemospray (TC-325, Cook Medical Inc, Winston-Salem, NC, USA), a new adsorptive nanopowder hemostatic agent for endoscopic treatment of high-risk bleeding peptic ulcers, provides significant ease of administration compared to the combined conventional technique of saline-adrenaline injection with mechanical clip or heater probe applications. The Hemospray powder is easily applied on ulcers at difficult endoscopic positions and ulcers with fibrotic bases, where the combined conventional technique has limited efficacy. Building up on preliminary work from small single-arm studies, the investigators aim to establish the efficacy and safety of Hemospray in treating bleeding peptic ulcers in comparison with the combined conventional technique. The investigators propose a pilot study to establish our centre's feasibility of performing a prospective, randomized, parallel group trial, which compares the efficacy of Hemospray with the combined conventional technique, in the endoscopic treatment of high-risk bleeding peptic ulcers. Patients with high-risk bleeding peptic ulcers will be treated with Hemospray to determine its initial hemostasis rate (defined as endoscopically verified cessation of bleeding for at least 5 minutes after endoscopic treatment), rebleeding rate (recurrent hemorrhage during a 4-week period following the initial hemostasis) and its safety profile.
Endoscopic high-frequency soft coagulation is available for the management of bleeding or nonbleeding visible vessels during endoscopic submucosal dissection. However, its efficacy on peptic ulcer bleeding has not been elucidated so far. The aim of this study was to evaluate the efficacy of hemostasis with soft coagulation using hemostatic forceps by comparing it with argon plasma coagulation (APC) in a prospective, randomized trial.
The purpose of this study is to investigate if a computerised decision-support tool used in general practice, can reduce the frequency of peptic ulcer bleeding related to the use of NSAIDs (Non-Steroidal-antiinflammatory-drug) and ASA( Acetylsalicylic acid) . On the basis of "The Danish general medical database" it is possible to develope a computerised decision-support tool, which enables the general practitioner (GP) in a "pop-up" window to get information on each patients risk-factors, when prescribing NSAID and aspirin to a patient at risk. This will give the general practitioner the oppurtunity to choose a different type of preparation or prescribe ulcer-preventive medicine at the same time. The decision-support tool will be tested in a randomized trial among general practitioners. The aim is to reduce the occurence of peptic ulcer bleeding. The expected outcome is a reduction in half of the total numbers of peptic ulcers.
