Abstract
Acute upper gastrointestinal bleeding (AUGIB) is a life-threatening emergency that results in high morbidity and mortality. The mortality rate varies between 4% and 14%.
It requires careful evaluation from the very first episode as an attempt to predict and reduce the risk of re-bleeding or death.
It is known that the outcome of a patient with AUGIB depends on first evaluation and resuscitation measures taken in the ED and that a clinically sensible & ideal tool to stratify the risk may safely reduce health care costs.
Different risk stratification systems were developed in last few years to distinguish between severe cases requiring admission & intervention and low-risk patients with AUGIB who can be managed as outpatients.
Admission Rockall score (pre-endoscopy Rockall score) and GBS Score can all be used for risk stratification in ED in patients presenting with AUGIB. Numerous comparative retrospective and prospective studies published so far have demonstrated differently variable accuracy and use of these scoring systems.
The aim of this study is to evaluate pre-endoscopic risk scoring systems (GBS and pre-endoscopic Rockall score) in risk stratification patients presented to ED with AUGIB to identify the need for admission & intervention or to discharge patients safely.
This study was conducted on One hundred (100) patients presented to ED with AUGIB of Menoufia University Hospital from August 2016 to August 2017.
All patients selected according to inclusion and exclusion criteria. All patients were evaluated and resuscitated in the Emergency Unit by emergency physicians then all patients were divided in to two groups: high risk &low risk group according to vital signs &need for blood transfusion. The GBS and pre-endoscopic Rockall score were applied, then data was collected to evaluate whether the patient is low risk or high risk according to the scores, then the results were compared with the result of endoscope which was collected with the aid of The Gastroenterology and Endoscopy Unit.
