Filter by:Small bowel capsule endoscopy is a test used to investigate for any abnormalities in the small bowel. The small bowel is about 4 meters long. The battery time of the capsule is about 8 hours. During this time the capsule takes pictures as it passes through the small bowel. In about 15-20% of capsule tests the battery expires before the capsule passes through the entire small bowel into the colon. Incomplete tests indicate that a variable portion of small bowel was not visualized. Incomplete tests are associated with potential missing of abnormalities in the portion of small bowel that was not reached. The capsule test may often required to be repeated but the problem of incomplete examination may persist. At present no medication has been approved to increase the rate of complete capsule tests. Prucalopride is a medication that has been approved in Canada and Europe for the treatment of chronic idiopathic constipation. Animal and human studies suggested that prucalopride may enhance the movement of the stomach and the small bowel. A recent presentation at a medical meeting suggested that prucalopride may accelerate the passage of the capsule camera through the small bowel without increasing the chance to miss a lesion in the small bowel. The purpose of this study is to asses if the administration of a single dose of prucalopride is going to decrease the time required by the capsule to move through the small bowel.
Background: Repeated bleeding from gastrointestinal vascular malformations remains to be a major therapeutic challenge. Methods: The investigators performed a randomised, double-blind, placebo-controlled, single centre study to assess the long-term efficacy and safety of thalidomide 100mg qn p.o. or placebo 100 mg qn p.o. administration for 4 months in subjects with recurrent gastrointestinal bleeding due to vascular malformations. Patients with at least six episodes of bleeding in the prior year due to vascular malformation were randomly grouped, prescribed a four-month regimen of either 100mg of thalidomide or 100 mg of placebo orally one time daily, and monitored for at least one year. The primary end point was defined as the patients whose rebleeds decreased from baseline by ≥ 50% at 12 months. Rebleeding was defined based on a positive fecal occult blood test (FOBT) (monoclonal colloidal gold color technology) at any visit after treatment. Secondary outcomes included the changes from baseline in participants dependent on blood transfusions and transfused packed red cell units, bleeding episodes, bleeding durations, and hemoglobin levels at 12 months. Statistical significance was defined at P < 0.05.
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.
The primary aim of this study is to compare efficacy of "early endoscopy" and "non-endoscopic treatment" for management of acute upper gastrointestinal (UGI) bleeding in patients with recent acute coronary syndrome (ACS). This study will also compare rates of surgery, repeated intervention (endoscopy or TAE), rebleeding and complications between two groups.
Acute gastrointestinal bleeding is a common medical problem. When patients with gastrointestinal bleeding present with melena (dark, tarry stool) the blood loss is usually originating in the upper gastrointestinal tract (esophagus, stomach or duodenum) and first step in evaluating the patient is an upper endoscopy; which allows direct visualization of the esophagus, stomach and duodenum. However, the cause of bleeding is located in the small bowel or colon in 20-30% of patients who present with melena. Traditionally colonoscopy has been the next test preformed if upper endoscopy does not identify the cause of melena/ gastrointestinal bleeding, however less than 25% of patients who present with melena have bleeding originating in the colon, and the remainder of patients have bleeding originating in the small intestine, which can only be fully evaluated with video capsule endoscopy (a pill camera which is swallowed and takes pictures while it travels thought the small bowel and colon). Currently patients only undergo video capsule endoscopy if colonoscopy does not identify the cause of bleeding. The investigators are preforming a randomized study which seeks to determine if colonoscopy or video capsule endoscopy is a better way to identify the cause of gastrointestinal bleeding in patients who present with melena and have normal findings on upper endoscopy. To do this the investigators will enroll patients who present with melena prior to their upper endoscopy and if the cause of bleeding is not identified at that time patients will be randomized to video capsule endoscopy (with the capsule being placed into the small bowel during the upper endoscopy) or next day colonoscopy.
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.
Pancreatic ductal adenocarcinoma is the fourth cause of death in the Western world. About 40% of pancreatic cancer patients were diagnosed as locally advanced unresectable status without distant metastasis. Concurrent chemoradiotherapy (CCRT) was a reasonable treatment modality for locally advanced pancreatic cancer. However, several adverse events of chemoradiation could lead unfavorable treatment results, which included unique gastrointestinal (GI) toxicities, such as ulcer and hemorrhage in the stomach and duodenum that are included in the radiation field. According to the study in the investigators hospital, 45% of locally advanced pancreatic cancer patients treated with CCRT suffered from GI ulcers, and among them, 65% of the patients experienced the significant hemorrhage events. Although these GI toxicities, the studies for radioprotective agents were limited. Albis® is a newly developed drug comprised of ranitidine, bismuth and sucralfate. The investigators will investigate the radioprotective effect of Albis® for locally advanced pancreatic cancer patients treated with CCRT.
The non-variceal upper gastrointestinal bleeding is defined as gastrointestinal bleeding located proximal to the angle of Treitz, whose cause is not related to esophagogastric varices or gastropathy of portal hypertension. Animal studies showed no absorption in the GIT and disposal within 48 hours of application, and no reported cases of obstruction. Recently, a prospective study involving 20 patients with upper gastrointestinal bleeding, showed that the application of hemospray ® promoted hemostasis in 95% of cases, confirmed by endoscopic revision 72h after application without any complication.
