Objectives: Bleeding from gastroesophageal varices is the most serious and life-threatening complication of cirrhosis and accounts for 10% of all cases of bleeding from the upper GI tract. It is essential to identify and treat those patients at the highest risk because each episode of variceal hemorrhage carries a 20 percent to 30 percent risk of death, and up to 70 percent of patients who do not receive treatment die within one year of the initial bleeding episode. The aim of this study is to determine the clinical predictors of bleeding esophageal varices and study the role of F VII (factor VII) and vWF (von willebrand factor) in predicting bleeding in patients with eosphogeal varices. Methods: A case control study was done on all patients with esophageal varices admitted at Sohag and Qena faculty of medicine hospitals from January 2012 to August 2013. Various clinical, laboratory and endoscopic variables were tested to determine the predictors of esophageal bleeding. Results: Among 300 patients with esophageal varices, 80 percent was due to hepatitis C virus (HCV), 18 percent was due to hepatitis B virus (HBV), and 2 percent had both HCV and HBV. As an etiologic factor for their liver disease, hemoglobin was 10.12 ± 2.26 g/l, platelet count 135.55 ± 65.94 × l09/l, prothrombin time 14.1 ± 0.92 second, albumin 2.88 ± 0.71 g/dl, ALT 48.25 ± 24.15 u/l, total bilirubin 1.92 ± 1.36 mg/dl. Factor VII was 27.4 ± 8.92 percent and vWF was 188.33 ± 13.66 IU/dl. Splenomegaly was reported 79.6 percent, 90.3 percent had ascites. 35 percent had grade III esophageal varices, 29 percent had four-column esophageal varices on endoscopy, 13.7 percent had concomitant gastric varices and 38.3 percent had portal hypertensive gastropathy. Platelet count, presence of red color sign, the number of columns of esophageal varices, presence of portal gastropathy on eosphagogastroduodenoscopy (EGD) showed a significant positive correlation with bleeding. There is a significant decrease of FVII and a significant increase of vWF in bleeding group in comparison with non bleeding group. Conclusion: Thrombocytopenia, presence of encephalopathy and endoscopic findings of large varices, presence of red color sign, and portal hypertensive gastropathy were found to be predictors of esophageal variceal bleeding. Increase of vWF and decrease of FVII are laboratory predictors of esophageal variceal bleeding.
