Abstract
Backgroud: Acute non- variceal upper gastrointestinal bleeding (ANVUGIB) is a common problem in everyday clinical practice. Among its most frequent causes are duodenal and gastric ulcers, erosive esophagitis, gastritis, duodenitis, Mallory-Weiss syn¬drome, and the upper gastrointestinal tract tumors. Mortality in this group of patients accounts for 5-15% .Rebleeding is considered the most important risk factor for mortality and occurs in 10–30% of those successfully treated. Aim of the work: The aim of current work was to assess the predictive value of Rockall Score when dealing with patients with ANVUGIB at Mansoura university hospital,The primary outcome was a composite endpoint of inpatient mortality, rebleeding, need for blood transfusion, or need for surgical intervention. Patients&Methods: Patients_Inclusion criteria:Patients with a primary diagnosis of acute upper gastrointestinal bleeding. Exclusion criteria: patients with acute variceal or obscure upper gastrointestinal bleeding. Methods_1.Complete history taking: 2.Through clinical examination: 3. Laboratoryinvestigation, including:Complete blood count ,Cross match blood,Coagulation profile,Liver profile,Renal function test and electrolytes (creatinine, sodium, potassium), Hepatitis markers: (HBsAge),HBcAb and (HCV Ab) 4- Abdominal ultrasonography.5-ECG 6-Pre-endoscopic Management by Initial patient evaluation and hemodynamic resuscitation. 7-Emergency Esophagogastroduodenoscopy. Treatment after first or failed endoscopic treatment and calculate of Rockall score. Results: The current study concluded that the area under curve (ROC) was 0.904 (p˂0.001) with the highest sensitivity and specificity revealed the Rockall result in the diagnosis of recurrent bleeding was more than 5.5 points cut with 94.1% and 65.4%. (5.3%) of the patients during the study period; 5 cases (33.3%) in the high-risk group, 3 cases (2.8%) in the moderate risk group, and no cases in the low-risk group = 0.002). There were statistically significant differences (p˂0.05) between the risk of Rackall-based outcome in active bleeding, recurrent bleeding, and compliance with the highest frequencies recorded in risk groups. Conclusions: In our results suggest that the Rockall risk scoring system had satisfactory validity for the prediction of rebleeding and mortality in patients with acute non-variceal UGIB, and was validated as a useful scoring system for stratifying patients into high-risk and low-risk categories for mortality and in-hospital rebleeding.
