ABSTRACT

Introduction: Appendicitis is the most frequent reason of surgical abdominal pathology in pediatrics. The aim of this work is to know the incidence of appendicitis and the correlation between surgical finds with previous cases, clinical information and paraclinic, as well as determine the correlation of the appendicular phase with the histopatologic diagnosis.
Material and Methods: Retrospective study, descriptive observation. Between 2004 and 2008 it was revised 817 files that diagnosed appendicitis, 562 filled the criteria of incorporation. It was used descriptive statistics, analysis of variance, logistic and statistical regression non parametric.
Results: Of the 562 cases, 352 (63 %) were males’, whose average age was 10.4 years. The average time of evolution was 34.6 hours and 53 % received treatment before the diagnosis. The frequent symptoms are pain (98 %), nausea (89 %) and vomit (56 %). The sensibility for pain was 88 %, McBurney 92 % and Psoas 51 %. However, it was discovered that it existed significant difference between the amount of leukocytes in the phase of appendicitis (P=0.0009) and a coefficient of association of 0.3. Nevertheless, it exists a correlation between the time of evolution, the phase of appendicitis and the age group among each group. The phases of appendicitis are not influenced with the treatment before the diagnosis (chi squared P ‹ 0.9) but with the time of evolution (chi squared ‹ 0.0001). It was observed a correlation of the previous treatment with the time of evolution (hours) which is major when there it is received medicine (t of student P ‹ 0.0001). As for the degree of conformity between the appendicular phase with the diagnosis histopatologic, the coefficient kappa is of 0.2543.
Discussion: Appendicitis affects with major frequency the teen and school groups. More than half of the patients’ received some form of treatment before the diagnosis. There exists a high sensibility, proof of diagnostic pain and McBurney. There is a significant difference between the amount of leukocytes and the phase of appendicitis. There are variations in the correlations between the time of evolution, phase of appendicular and age groups. The previous established treatment significantly modifies the time of evolution. As a result, there is a difference between the phase of appendicitis and pathological diagnosis.
