Filter by:Non-variceal acute gastrointestinal bleeding is a common and potentially life-threatening problem. The conventional treatment of this condition is for esophagogastroduodenoscopy (OGD) for haemostasis. Treatment methods include heater probe, clipping and injection of adrenaline. Recently, a new device called the Over-the-scope clip (OTSC) has been device to treat perforations and bleeding in the gastrointestinal tract. Therefore, the aim of the study is to compare between the treatment outcomes between OTSC and conventional endoscopic haemostatic methods in ulcers that are of high risk for rebleeding.
Low-dose aspirin is the mainstay of treatment for patients with coronary heart disease and stroke. However, low-dose aspirin increases the risk of ulcer bleeding. Current evidence indicates that 80 - 100 mg of aspirin daily provides good protection against vascular events and the risk of ulcer bleeding is low (about 1% per year). Since the overall risk of bleeding is low, aspirin users who do not have previous ulcer disease do not require prophylaxis with anti-ulcer drugs. In contrast, aspirin users with a history of ulcer disease have a 2- to 4-fold increased risk of ulcer bleeding. The best strategy for reducing the risk of bleeding in high-risk aspirin users remains unclear. Current strategies for high-risk patients include the use of anti-ulcer drugs, elimination of risk factors (e.g. Helicobacter pylori), or the use of enteric-coated aspirin. Although co-therapy of aspirin with an acid suppressant reduces the risk of ulcer bleeding, drug compliance may limit its clinical usefulness particularly in patients who are already receiving multiple drugs. The efficacy of enteric-coated aspirin in preventing ulcer complications showed conflicting results. One study found that enteric-coated aspirin increases the risk of ulcer bleeding. A recent study showed that enteric-coated aspirin causes minimal acute gastric injury. The investigators postulated that among patients without H. pylori infection and a history of ulcer bleeding who continue to use low-dose aspirin, enteric-coated aspirin reduces the long-term risk of ulcer complications to a level that is comparable to that of average-risk aspirin users.
