Abstract
Acute upper gastrointestinal bleeding (AUGIB) is a life-threatening emergency that results in a high morbidity and mortality and therefore requires admission to hospital for urgent diagnosis and management. Despite recent advances in endoscopic and pharmacological management, AUGIB is still associated with considerable mortality and morbidity. Urgent proper triage of the patients in emergency departments and risk stratification according to risk scoring systems can help to identify patients for urgent diagnostic and therapeutic procedures. In recent years, several practice guidelines and risk scores that combine clinical and endoscopic parameters have been developed to assist physicians in the early stages of decision making. The aim of this study is to compare the performance of different scoring systems (Rockall scoring system, Glasgow-Blatchford score and AIMS65) in predicting the need for treatment and clinical outcomes (re-bleeding, duration of hospitalization, need for blood transfusion and death) in patients with acute variceal bleeding. We studied one hundred cases (76males & 24females with mean age of 59.39±7.7years) of acute variceal upper GI bleeding, for each case we calculated those three scores and we gave them the appropriate medical & endoscopic management. Then we follow our patients for four outcomes; re-bleeding, need for blood transfusion, duration of hospitalization and death. The study was done within 6 months. According to our study we found that AIMS65 was superior for predicting the re-bleeding, GB score was superior for predicting the need for blood transfusion and no superiority was detected as regards duration of hospitalization and mortality among the three scores used.
