Filter by:The goal of this cross-sectional study is to evaluate the efficacy of current infection marker (CIM) method for H. pylori detection. The main questions it aims to answer are: - To evaluate the efficacy of CIM method for H. pylori detection compared to rapid urease test(RUT), histopathology, polymerase chain reaction (PCR), and urea breath test (UBT) in patients who presented with upper gastrointestinal hemorrhage from peptic ulcer, and their sensitivity, specificity, accuracy, positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio, and negative likelihood ratio. - To evaluate the advantages of CIM method for H. pylori detection comparing to RUT, histopathology, PCR, and UBT in patients who presented with upper gastrointestinal hemorrhage from peptic ulcer as net reclassification index (NRI). - To study the associated factors in false negative value of H. pylori detection methods with CIM, RUT, histopathology, PCR, and UBT.
In managing bleeding gastroduodenal ulcers, endoscopic control of bleeding is the first line treatment-further bleeding after endoscopic hemostasis is associated with a 3-fold increase in mortality. Large ulcer size (> 20 mm) predicts further bleeding. These ulcers erode into arteries of significant size (>2 mm) from either the gastro-duodenal or left gastric arterial complexes. An over-the-scope clip is an endoscopic clamp device with a high tensile strength. It can compress sizeable arteries, and firmly anchor onto the ulcer base avoiding recurrent bleeding from clip dislodgement. It therefore offers secure and durable hemostasis. In the proposed randomized controlled trial, the investigators hypothesize that after initial endoscopic control of bleeding from large gastro-duodenal ulcers (20 mm in size or more), adding an OTSC can prevent recurrent bleeding and improve patients' outcomes. Investigators enroll patients with bleeding from large ulcers as defined. After initial endoscopic control of bleeding using injection with diluted epinephrine, these patients are randomized, during endoscopy, to receive standard treatment (thermo-coagulation or hemo-clips) or an added OTSC. The primary endpoint is recurrent bleeding over 30 days confirmed on endoscopy. Secondary endpoints include the need for rescue treatment; endoscopic, angiographic embolization or surgery, red blood cell (RBC) transfusion, hospitalization, and bleeding related and all-cause mortality.
Find out if there is a significant difference between clinical outcome among the patients with bleeding peptic ulcer treated with oral omeprazole compared to those treated with intravenous omeprazole.
The researcher's primary hypothesis is that VCE allows for safe outpatient management of ED patients with suspected upper GI hemorrhage. A prospective multicenter randomized control trial was designed to investigate the safety of this approach.
