[Indication of appendectomy in the recurrent abdominal pain].
BACKGROUND
The frequency of the recurrent abdominal pain without demonstrable pathology is high and in occasions it takes to the surgeon to practice an appendectomy. In most of the cases the pain disappears. This performance although subjective, it doesn't base on objective data, what takes us to carry out this work.


METHODS
The study is carried out in 47 patients with recurrent abdominal pain and subjected to appendectomy, 17 were excluded by diverse causes. The vermiform appendixes were studied by morphological and immunohistochemical methods, using the monoclonal antibodies, valuing morphologic sing of a chronic inflammation of the appendix.


RESULTS
100% of the samples studied presented microscopically chronic inflammatory changes microscopically. We observe fibrose in 100%, lympho-plasmocytic inflammatory infiltrate in 60% and a lymphocytes T prevalence has more than enough lymphocytes B.


CONCLUSIONS
Our results support the existence of a clinical-pathological condition that can be defined as chronic appendicitis and therefore it justifies the appendectomy in recurrent abdominal pain when another disease has been excluded.
