In all outcome measures the APACHE scores generate small and of similar extent changes in probability. The Balthazar score is superior to other scoring systems in predicting acute pancreatitis severity and pancreatic necrosis. However the Ranson and APACHE scores perform slightly better with respect to organ failure prediction.

The APACHE III offers little, if any, advantage over the APACHE II score. Ranson criteria proved to be as powerful a prognostic model as the more complicated APACHE II and III scoring systems, but with the disadvantage of a 24-hour delay.

Background: Intestinal tuberculosis is a rare disease in western countries, affecting mainly immigrants and immunocompromised patients. Intestinal tuberculosis is a diagnostic challenge, especially when active pulmonary infection is absent. It may mimic many other abdominal diseases.
