Analysis of scores in diagnosis of acute appendicitis in women.

Acute appendicitis is a common surgical condition that requires prompt diagnosis. Besides modern imaging techniques, scoring systems, based on clinical signs and symptoms and routine laboratory assessments, have been used as a diagnostic aid. However, differences in sensitivities and specificities were observed if the scores were applied to various populations and clinical settings. The purpose of this paper is to assess validity of three scores (modified Alvarado score, Ohmann score and Eskelinen score) for diagnosis of acute appendicitis in women. 126 female patients admitted for suspicion of acute appendicitis in a tertiary hospital emergency department were analyzed prospectively. Modified Alvarado score, Ohmann score and Eskelinen score were calculated at admission and compared to final diagnosis. All patients with modified Alvarado score 7 or more had acute appendicitis (100% specificity) and it can be used to determine the need for immediate appendectomy. Values of Ohmann score greater than 6 resulted in 0.9% rate of overlooked appendicitis. Besides obvious educational role, scores may help to determine the group of patients who require immediate appendectomy, therefore expediting treatment and avoid unnecessary observation or more lengthy diagnostic procedures that require highly educated and skilled senior staff: No single score may be used alone to dictate or decline surgery. Different cut-off points may also be considered for different subpopulations.
