Is appendicitis a place for clinical judgement?
Acceptable rates of negative appendix and complicated appendicitis can be obtained from clinical data. The presence of complicated appendicitis is primarily associated with a longer delay before first medical consultation.
Traditional indices of SBE, BE(UA,) lactate, pH, AG, and APACHE II all discriminated well between survivors and non-survivors. In this group of patients the SIG, SIDeff, and SIGapp appear to offer no advantage in prediction of outcome and their use as prognostic markers can therefore not be advocated.
