Trauma has been called the neglected disease of modern society and the most common cause of death under 45 years. The majority of cases being non-penetrating, the so-called blunt abdominal trauma(BAT). Abdominal findings may be absent in 40% of patients with hemoperitoneum as long as radiological investigations are overpriced, not available all the time and .Therefore, there is an essential need for a rapid evaluating method to define patients requiring surgical intervention based on clinical signs as called CASS(CLINICAL ABDOMINAL SCORING SYSTEM).
The aim of the study is to evaluate the accuracy, sensitivity and specificity of CASS in predicting of the necessity of laparotomy in BAT
Zagazig University Hospitals in the period from November 2017 to May 2018 on 46 patients with only blunt abdominal trauma grouped into three categories:Priority (1) : 12 or above, Priority (2) :9-11 & Priority (3) :8 or less according to the CASS
We found that CASS shows both higher sensitivity and specificity over other modalities such as; U/S and CT .scan in BAT patient
