Pak J Med Health Sci Jan ;7(4):1140-2.

Aim: To determine the validity of upper gastrointestinal bleeding etiology score for determining variceal bleeding by doing esophagoduodenoscopy as gold standard. Study design: Cross sectional validation survey Study setting: Department of Medicine, Aviceena Teaching Hospital, Lahore and Department of Medicine Services Hospital Lahore. Duration of study: Six months after approval of synopsis (From Jan 2013 to June 2013) Results: The results of the study reveal majority of the patients i.e. 30.83%(n=37) between 51-60 years of age, mean and standard deviation was recorded as 35.64+7.75 years, 55.83%(n=67) female and 44.17%(n=53) were male patients, frequency of variceal bleeding (on esophagoduodenoscopy as gold standard) was recorded in 13.33%(n=16) while 86.67%(n=104) had no variceal bleeding, the validity of upper gastrointestinal bleeding etiology score for determining variceal bleeding by doing esophagoduodenoscopy as gold standard shows sensitivity, specificity, positive predictive value, negative predictive value and accuracy rate was calculated as 78.57%, 95.28%,68.75%, 97.12% and 93.33% respectively. Conclusion: The result of the study determined that etiology score for determining variceal bleeding by doing esophagoduodenoscopy as gold standard is valid and having considerable specificity and sensitivity in patients presenting with upper gastrointestinal bleeding.
