This study is designed as a multicenter prospective data recording study to document the performance of the DAT clip as part of standard medical care of patients. No experimental interventions will be performed.

Hematological Disorders in Patients With GI Angiodysplasia

The aim of this study will be to assess the association between GIT angiodysplasia with any hematological disorders as von Willebrand factor and Prognostic value of von Willebrand factor on patient's outcomes as risk of rebleeding and hospital mortality

High Dose Oral Omeprazole in High Risk UGIB

Peptic ulcer bleeding is the most common etiology in upper gastrointestinal bleeding all over the world. After endoscopic treatment, proton pump inhibitor (PPI) is recommended to prevent re-bleeding. Intravenous PPI is recommended as a standard treatment. In the past, there were many trials showing the efficacy of high-dose oral PPI after endoscopic hemostasis but most were industrial sponsor which assessing an expensive PPI. Moreover, the number of patients in those studies were insufficient to confirm a non-inferiority outcome in term of rebleeding by using oral PPI. This study will evaluate a high-dose, local-made PPI (omeprazole) in peptic ulcer treatment after successful endoscopic hemostasis compared to standard IV PPI continuous drip in term of rebleeding, as well as 24-hour gastric pH monitoring.
