Abstract
”Upper GI bleeding is a medical emergency that results in substantial morbidity, mortality. It can present as hematemesis, melena or hematochezia. Upper GI bleeding is classified as Non-variceal UGIB and Variceal UGIB. The mortality of our study is 9%. The most common predictors of in-hospital mortality include: hemodynamic instability; Mean Arterial Pressure (MAP <70), severe bleeding, presence of sepsis (Mean TLC=13.15) and presence of risk factors as old age, CKD and advanced liver disease. The aim of this study was to characterize patients with UGIB, to evaluate the risk factors for UGIB, to describe the clinical features of patients and to identify the predictors of in-hospital mortality. It carried out in the Hematemesis and melena unit on 322 patients at Mansoura Emergency Hospital. All patients of the study subjected to the following: Complete history taking, Clinical examination and U/S findings. Laboratory investigations.Need for transfusion of blood, platelets and fresh frozen plasma.Upper gastrointestinalendoscopy (findings and interventions).Severity assessment according to (Rockall Score).Out-comes of patients.The results of this study showed that: Findings of current endoscopy including oesophageal varices (OVs) in 74.5%, fundal varices (IGV) in 12.1%, moderate PHG in 40.4%, severe PHG in 31.7%, esophageal mass in 1.2%, gastritis in 15.5%, duodenal ulcer in 14.9%, gastric ulcer in 6.5%, Cameron ulcer in 2.2%, gastric mass in 2.2%, dieulafoy lesion in 0.3% and GAVE in 2.5% of the cases. The most common predictors of in-hospital mortality include; hemodynamic instability, (MAP <70), severe bleeding and presence of sepsis (cut off for mortality is TLC≥18.6/mm3. Presence of risk factors as (CKD), old age, malignancy and advanced liver disease.
