[Appendicitis in childhood: correlation of clinical data with histopathological findings].
BACKGROUND
Quantifying the histopathological diagnoses of appendectomies in daily routine paidopathology results in a high percentage of appendices without histomorphological sign of acute inflammation. To identify clinical factors significantly associated with the morphological diagnosis, histopathological findings and clinical data--documented in patients' files--were examined.


METHODS
All 856 children (age: 5 m-15 yrs) whose appendix had been resected within a 7-year-period were--depending on the histopathological diagnoses--allocated to the group "appendix without" resp. "appendix with signs of acute inflammation".


METHODS
All files were examined concerning anamnestic data, clinical signs of acute appendicitis and laboratory parameters. The data were analysed by χ(2)-test and Wilcoxon-test concerning differences between the 2 groups with regard to the anamnestic and clinical facts and parameters. Using binary logistic regression, these clinical parameters were analyzed in correlation with the histopathological diagnoses.


RESULTS
By consideration of the factors "leucocyte count", "vomiting" and "percussion tenderness" 75% of the children would have been allocated to the accurate postoperative pathomorphological diagnosis.


CONCLUSIONS
There was a significant correlation of "leucocyte count", "vomiting" and "percussion tenderness" with histopathology in 75% of the children. As hence 25% were not allocated correctly this combination is no unequivocal combination for prediction or exclusion of an acute appendicitis. Hence, even with these statistically significant parameters a comparably high percentage of falsely-positive appendectomies has to be anticipated.
